Abstract
A surgical stapler having a supporting frame, including a stationary jaw having an anvil, a movable jaw, a replaceable staple cartridge carried by the movable jaw, a mechanism for approximating the cartridge relative to the anvil, and a mechanism for firing the device so as to crimp the staples against the anvil in a manner to enable the surgeon to substantially simultaneously place one or more rows of surgical staples in organs or tissues. The device includes interrelated, cooperating first and second locking mechanisms for positively preventing refiring if the staple cartridge is spent and for providing a tactile sensation to the surgeon to indicate that a spent staple cartridge is present within the instrument.
Description
0 2 iB f i i o BACKGROUND OF THE INVENTION
Field of the invention The present invention relates generally to surgical stapling devices. More particularly, the invention concerns a novel surgical stapler that embodies first and second cooperative, interrelated safety mechanisms that positively prevent the surgeon from refiring the instrument after the staples have been fired, the tissue clamping jaws reopened and =the movable jaw guide pin withdrawn.
Discussion of the Invention Surgical staplers are frequently used in surgical procedures for suturing body tissue as, for example, intestinal and gastric walls. Such devices typically include a staple holder, or cartridge, which is disposed on one side of the tissue to be fastened and an anvil assembly on the other side of the tissue. During the surgical procedure, the staples are driven from the cartridge by some type of actuator so that the ends of the staples pass through the tissue and then are bent inwardly by the anvil so as to produce an array of finished fasteners in the tissue. During the typical suturing process, pusher members associated with the cartridge are controllably advanced by the operating mechanism of the instrument in a manner to urge the staples out of the cartridge, through the tissue and forcibly against the anvi.l.
Possibly the most frequently used type of surgical stapler is the linear stapler, which is a device that enables the surgeon to simultaneously place one or more rows of surgical staples in body tissue or organs. By way of example, a typical procedure is a pneumectomy, that is a removal of a portion of a patient's lungs. The linear stapler can be used several times during this procedure, including for the occlusion of the pulmonary artery prior to its resection. For this later use, the surgeon first clamps the jaws of the stapler across the 02h181310 artery, then forms the staples and, prior to reopening the stapler jaws, cuts the artery using the edge of the staple jaws as a guide.
Some prior art linear staplers of conventional design embody a stationary jaw including a staple forming anvil, a movable jaw which carries the staple cartridge and a movable lever which, when initially actuated, causes the stapling cartridge to be moved into an approximated position wherein the cartridge is adjacent to the anvil against which the staples are formed. A retractable guide pin, which typically extends through a guideway in the staple cartridge, guides travel of the movable jaw and staple cartridge and functions to retain the tissue between the jaws during the approximation step. In the approximated position the tissue is captured and compressed between the cartridge and the anvil to a thickness small enough to ensure: proper staple formation.
When the operating lever on the handle of the instrument is squeezed a second time, the staples are fired, that is the staples are forcefully urged toward the anvil thereby penetrating the tissues to be stapled and causing the staples to be formed into a"B"-shaped configuration which ensures tissues coaptation and hemostasis. After the staples are formed, the surgeon can, if desired, cut the tissue using the edge of the staple jaws as a guide and then retract the guide pin and reopen the instrument. As the instrument opens, the stapled tissues are freed and the instrument is returned to its original starting configuration. One such prior art linear staple is sold by 3M Health Care of St. Paul, Minnesota under the name "PI-55".
The environment in the operating room during a surgical procedure can be, at times, complex and confusing, even for experienced operating room staff. For example, after the first staple line has been placed by the surgeon, the stapling ~~~~13 10 instrument is passed back to the scrub nurse, whose job it is to remove and discard the empty cartridge, and replace it with a fresh one, prior to passing it back to the surgeon for another application. If the scrub nurse becomes accidentally distracted, he or she may forget to do so, and might simply pass the instrument containing the empty cartridge back to the surgeon. In prior art surgical staplers, the surgeon can determine that the instrument has been approximated by merely observing the instrument. However, nothing in the appearance of some of the prior art instruments indicates that the staples have been fired. Other prior art instruments, such as the "PI-55" offer a visual indicator, but this indicator is located next to the tissues, i.e., in an area where visibility might be limited. If the stapler is misused in this manner, a potentially serious situation can arise since frequently, prior to reopening the inst:rument, the surgeon cuts the stapled tissues. Should the surgeon erroneously conclude that he has fired the staples when, in fact, he has only approximated the cartridge to the anvil and, therefore, proceed to cut unstapled tissues, a hemorrhage could occur when the surgeon reopens the instrument. This situation is further aggravated by the fact that, as a general rule, the prior art staplers provide so much mechanical advantage tc> the user that the force needed to be applied on the lever to form the staples is often no greater than the force required to approximate the cartridge to the anvil. Accordingly, the prior art devices fail to provide any tactile feedback that the instrument has, in fact, been fired.
In an application filed by the present inventors on March 7, 1995, two approaches to preventing the surgeon from refiring a spent cartridge are disclosed. United States Letters Patent No. 5,413,267 issued to Solyntjes et al. discloses an alternate means for indicating that the staple cartridge contained within the instrument has been fired. However, unlike the apparatus 0 ~ 3 of the present invention, the Solyntjes et al. apparatus does not include first and second cooperatively, interrelated safety mechanisms which provide an effective means for indicating to the surgeon that the staple cartridge then in place within the instrument has been fired.
The thrust of the present invention is to provide interrelated locking mechanisms which cooperate to positively indicate to the surgeon that the staples have, in fact, been fired from the cartridge which is in place within the device and to mechanically prevent operation of the staple firing mechanism. As will be better understood from the description that follows, once the stapl.es have been fired, the clamping jaws opened and the guide pin withdrawn, the first and second locking mechanisms cooperate in a highly novel manner to effectively disable the device until a filled staple cartridge is in place within the instrument and the guide pin moved into a fully advanced position relative to the stationary jaw. So long as a fresh staple cartridge is present within the instrument, the device can be used in normal fashion to clamp the tissue and fire the staples, but once the staples have been fired, the instrument is effectively disabled until the spent cartridge is replaced with a fresh, unfired cartridge.
In one embodiment of the invention, the first locking mechanism is carried by the staple cartridge, while in another form of the invention, the mechanism is connected to the movable jaw of the instrument. In either case the first locking mechanism functions to positively prevent complete advancement of the retractable guide pin. Unless and until the guide pin is fully advanced, the first locking mechanism will cooperatively interact with the second backup locking mechanism in a manner to prevent operation of the staple driving mechanism.

Referring to the drawings and particularly to Figures 1 through 3, one form of the apparatus of the invention for simultaneously emplacing a plurality of surgical staples into tissues and organs is there shown and generally designated by the numeral 12. The apparatus comprises an elongated supporting frame 14 having first and second longitudinally extending spaced walls 16 and 18 defining an interior space 20 (Figure 3). Forming an integral part of frame 14 is a stationary jaw assembly 21 which includes an anvil portion 22 having a staple-engaging face 24.
Slidably movable within frame 14 from a first retracted position to a second forward position is a movable jaw assembly 26. Removably deployed within movable jaw assembly 26 is a staple cartridge 27 (Figure 7) which contains a plurality of surgical staplers that are adapted to pass through the tissue to be stapled and then crimped against face 24 of anvil 22 in a manner. presently to be described.
As indicated in Figure 7, a pusher member 28 is associated with cartridge 27 for movement relative to the cartridge housing 27a between a first extended position as shown in Figures 7 and 9 to a second stapled fir.ed position shown in Figure 10. During the firing step, pusher member 28 engages the staples contained within the staple cartridge and drives them forwardly into pressural engagement with face 24 of anvil portion 22. As the staples are simultaneously driven from the staple cartridge, they will engage the anvil face and typically crimp into a crimped shaped roughly corresponding to the shape A'A .2 1 of the letter "B". As the staples are appropriately crimped, they will, of course, join together the layers of tissue or organ "T" between face 24 of the anvil and the forward face of the staple cartridge.
In operating the instrument, when the staple cartridge, along with its cooperating pusher member, is disposed in the spaced-apart relationship with anvil 22 as shown in Figure 7, tissue or human organ can be placed in the open space between the staple cartridge and face 24 of the anvil. After the tissue has been appropriately positioned between the staple cartridge and the anvil, guide means, which here includes an elongated retractable guide pin 29, is moved forwardly to the second advanced position shown by the phantom lines in Figure 7. Next, using the approximation means of the invention, movable jaw assembly 26 along with staple cartridge 27, is moved forwardly of the apparatus to a location where it is closely adjacent face 24 of anvil 22 (see Figure 9). During travel of jaw assembly 26 and staple cartridge 27, guide pin 29 maintains proper alignment of the components and also functions to retain the tissue "T" in position between jaw assemblies 21 and 26.
As can best be seen by referring to Figures 1, 2, and 3, movable jaw assembly 26 includes a pair of spaced-apart approximation members 30 and 32, the forward portions of which define the cartridge receiving portion 26a (Figure 2). Members and 32 are disposed between side walls 16 and 18 and, in a manner presently to be described, are slidably movable with respect thereto from a first retracted position shown in Figures 2 and 7 to a forward, approximated position shown in 30 Figure 9.
In the embodiment of the invention shown in Figures 1 through 10, the means for moving the movable jaw assembly toward the stationary jaw includes a handle assembly 34 which comprises a fixed handle portion 36 and a movable handle portion, or actuating lever 37, which is pivotally connected to fixed handle portion 36 in the manner best seen in Figures 1 and 4. Additionally, these approximation means further include an operating linkage 34a made up of pivotally interconnected first and second operating links 38 and 40 (Figure 4). The first end 38a of link 38 is pivotally interconnected both with frame 14 and with a third link member 42 by a pivot pin 39. The second end 38b of link 38 is pivotal:ly connected to link 40 proximate its first end 40a by a pivot pin 39a. The second end 40b of link 40 is operably associated with members 30 and 32 and moves these members forwardly as the linkage is moved into the collapsed, overcenter configuration shown in Figures 9 and 10. With this construction, when actuating lever 37 is moved from the first position shown in Figure 1 to the second position shown in phantom lines in Figure 9, linkage assembly 34a will be moved by lever 37 from the extended position shown in Figure 1 to the collapsed position shown in Figure 9. As linkage 34a moves into this collapsed, overcenter position, members 30 and 32 are urged forwardly to the position shown in Figure 9. A first biasing means, shown here as an enlongated coil spring 45 (Figure 4) yieldably resists depression of lever 37. Simi-larly, a second biasing means, here provided as a torsion spring 46, yieldably resists movement of linkage assembly 34a from the upraised position shown in Figure 1 to the collapsed or closed position shown in Figure 9. As will be discussed in the paragraphs which follow, spring 46 tends to automatically return linkage 34a to the upraised position when it is moved by a novel release means from the downward, overcenter position shown in Figure 9 toward the open, upstanding position shown in Figure 1.
It is to be noted that movement of the generally "T"
1 685 1 A, 1 1) shaped members 30 and 32, which are slidably received within spaced-apart walls 16 and 18 of frame 14, is yieldably resisted by a third biasing means which comprises an elongated coil spring 47 having an end 47a connected to the supporting frame and an end 47b connected to the members 30 and 32 (Figure 4).
Formed proximate the forward end of members 30 and 32 is the previously identified movable jaw assembly 26 which removably receives staple cartridge 27. With this construction, it is apparent that the forward movement of members 30 and 32 caused by the initial closing of lever 37 will result in the staple cartridge moving into the approxi-mated position wherein it is located adjacent anvil 22 (Figure 9). The device will remain in this approximated position until it is x=eleased by the release means of the invention in a manner presently to be described.
Following the approximation step, the staples can be driven through the tissue "T" and into pressural engagement with the anvil 22 by the operating means of the invention. In the form of the invention shown in the drawings, the operating means comprises a generally "T" shaped operating bar 56 which is slidably movable between members 30 and 32 from a first retracted position shown in Figures 2 and 9 to a second staple fired position shown in Figure 10. The operating means also comprises an operating member or link 52 which is pivotally connected to handle portion 37 for pivotal movement between first and second positions. As best seen in Figure 10, operating link 52 includes an end portion 52a which is movable into engagement with operating bar 56 following movement of lever 37 to its third retracted position shown by the phantom lines in Figure 10.
As can be observed by also referring to Figure 1, prior to the approximation step, operating link 52 is maintained in its first upraised position by the rearwardly positioned 4e :
A
members 30 and 32. However, upon movement of these members forwardly of the apparatus into the approximated position shown in Figure 9, and upon movement of handle portion 37 from its second downward position shown by the phantom lines in Figure 9 to its third upward position shown by the phantom lines in Figure 10, member 52 will pivot downwardly due to the urging of a fourth biasing means shown here as a torsion spring 56 (Figure 4). With member 52 in this downward position, movement of handle 37 into the fourth downward position shown by the solid lines in Figure 10 will cause end 52a of member 52 to engage the T-shaped bar 56 and cause it to move forwardly between member 30 and 32 from the position shown in Figure 9 to the forward staple fired position shown in Figure 10. As the T-shaped bar moves forwardly toward staple cartridge 27, it will engage the pusher members and force the staples from the cartridge through the tissue to be coapted and into pressural engagement with anvil 22. In the prior art staplers, spring 45 would then tend to urge lever 28 into its normal upraised position. Visual. observation of the device after firing would, therefore, require that the surgeon both remember to, and have the opportunity to, observe whether carriage pusher members 28 have disappeared from the field of view created by a hole XX (Figure 10) . If the pusher members are not visible, the surgeon could conclude that the cartridge had been fired. On the other hand, if the pusher members are still visible, the surgeon could conclude that the cartridge has not yet been fired. While this is better than no feedback at all, it is not ideally suited for the busy environment of the operatirig room nor to the lack of visibility associated with many procedures in which the stapler is used.
After the staples have been fired, the release means of the device is used to return the linkage assembly to its starting position. The release means shown in Figures 1 0 2 18' 1 '5 10 through 10 comprises a manually operated release pin assembly 66 which is movable within a slot 67 formed in the handle portion of the apparatus from a first downward position to a second upward release position (Figures 5 and 9). The release pin assembly 66 here includes a knob portion 68 which is interconnected with a shaft portion 70 that extends through and is guided by slot 67. The inboard end of shaft 70 is interconnected with linkage assembly 34a so that an upward movement exerted on knob 68 will move the linkage assembly from the downward, overcenter position shown in Figure 9 toward the upward, starting position shown in Figure 1. As knob 68 is moved upwardly, the linkage assembly will rapidly snap into the upward starting position as a result of the action of torsion spring 46.
Forming an important aspect of the present invention is the provision of cooperating, interrelated first and second locking means which function to effectively disable the instrument unless a fresh staple cartridge is in position within the movable jaw of the device. Tn the present form of the invention, the first lockout locking means functions to engage guide pin 28 in a manner to positively prevent its advancement toward the second advanced position shown by the phantom lines of Figure 7 wherein it is seated within bore 21a provided in stationary jaw 21. In a manner presently to be described, this first locking means uniquely cooperates with the second lockout locking means to prevent a staple firing advancement of operating bar 56 unless a fresh staple cartridge is in place within the instrument and the guide pin is fully advanced into its second advanced position. This unique backup feature provides a clear and unmistakable signal to the surgeon as to the condition of the cartridge that is in place within the instrument.
Turning to Figures 11 through 15 one form of the first locking means of the invention is there illustrated. This first locking means here comprises a novel locking mechanism 75 of the character best seen in Figures 11 and 15. Mechanism 75 is carried by movable jaw 26 and comprises a uniquely channelled platform 76 which is connected to movable jaw 26.
Carried by platform 76 is a first member 78, which includes a generally triangularly shaped pusher engaging extremity 80, and a second cooperating member 82 (Figure 5). Member 82 includes a yoke-like locking extremity 82a which, in a manner presently to be described, is receivable within a guideway 84 formed in pin 29 and is movable therewithin into locking engagement with longitudinally spaced apart locking shoulders formed at the opposite ends of the guideway (Figure 14). As best seen in Figures 14 and 14a, guideway 84 is formed by milling or otherwise forming the opposing sides of pin 29 in a manner to provide longitudinally extending, generally flat surfaces which define the guideway. Formed at one extremity of the guideway 84 is a shoulder 85 and formed at the opposite end thereof is a shoulder 86 (Figure 14).
Also comprising a part of the locking mechanism of this form of the invention is a biasing means for urging first member 78 outwardly of platform 76 and into engagement with pusher members 28a in the manner shown in Figure 11. The biasing means also functions to simultaneously urge second locking member 82 upwardly into engagement with guide pin 29 in the manner shown in Figure 11. In the embodiment of the invention shown in the drawings, the biasing means is provided in the form of a clip-type spring 89, the configuration of which is best seen by referring to Figure 15. When spring 89 is in position within block 76, leg 89a of the spring engages the inboard end 78a of member 78 and urges the member outwardly of the housing in a direction toward the pusher members 28.
In similar fashion, leg 89b of spring 89 engages the inboard end 82b of member 82 and tends to urge the member upwardly into pressural engagement with guide pin 29. Member 78 is provided with a generally V-shaped cutout portion 78c which lockably engages a fulcrum-like member 82c provided on member 82 when member 78 is moved by spring 89 into the extended position best seen in Figure 14.
Turning once again to Figure 11, it can be observed that with the movable jaw in the approximated position and with pusher members 28 extending rearwardly from the fresh staple cartridge 27 that is deployed within the movable jaw, forward movement of locking member 78, due to the urging of spring 89, will be prevented by the rearwardly extending pusher members 28. Similarly, in this configuration, the second locking pin 82 will be retained in its retracted position within block 76 by the fulcrum-like protuberance 82c of member 82 engaging member 78 in the manner shown in Figures 11 and 12A. However, upon operating bar 56 moving forwardly in a manner shown in Figure 13 to urge pusher members 26 into firing engagement with the staples disposed within staple cartridge 27, the pusher members will no longer impede forward movement of locking member 78. Accordingly, leg 89a of spring 89 will urge member 78 forwardly of the platform 76 in the direction of the arrow in Figure 13. As member 78 moves forwardly, or to the right as viewed in Figure 13, V-shaped slot 76c will move into register with the fulcrum-like protuberance 82a provided on member 82 thereby causing spring leg 84b to urge member 82 upwardly into the position shown in Figure 13 wherein yoke-shaped end portion 82a engages the outer cylindrical surface of guide pin 29. Following the staple firing step and during the subsequent retraction of guide pin 29, the yoke-shaped extremity 82a of member 82 will move into the guideway 84 formed on pin 29 and then into engagement with shoulder 85 in the manner shown in Figure 14.
~ ~ ~ a 11 ~a~,~ 10 If the surgeon attempts to advance the guide pin without replacing the spent cartridge, extremity 82a of locking pin 82 will move into engagement with shoulder 86 thereby blocking further advancement of the guide pin and providing a tactile sensation to the surgeon. In this regard, it is to be noted that the length of guideway 84 is such that the guide pin cannot be fully advanced to its forward most second position so long as locking pin 82 is in the extended position. Thus the tactile indication given to the surgeon as pin 82 engages shoulder 86 advises the surgeon that forward travel of the pin is blocked thereby providing a positive input that a spent cartridge is in place within the instrument.
Upon insertion of a fresh cartridge into the movable jaw assembly of the instrument, the extended pusher members of the fresh cartridge will move locking pin 78 to the left as viewed in Figure 14 against the urging of leg 89a of spring 89. This rearward movement of member 78 will also cause member 82 to be cammed downwardly against the urging of leg 89b of spring 89 so that the locking mechanism will be returned to the starting configuration shown in Figures 11 and 12A. With the component parts in this position and with blocking member 82 in its retracted location, it is apparent that guide pin 29 can be freely moved forwardly of the device and into its fully advanced second position. This freedom of movement of guide pin 29 into its fully advanced second position indicates to the surgeon that a fresh cartridge is in place within the instrument and that use of the instrument can safely proceed.
Referring particularly to Figures 1, 3A, and 6, one form of the second locking means of the invention is there illustrated and can be seen to comprise a locking gate 90 which is carried by handle portion 36 for movement between a first locking position shown in Figure 6 and a second release position shown in Figure 9B. In the present form of the 11 p i "~10 invention, the release means comprises an elongated release segment or member 92 which is slidably receivable within a central aperture 90a formed in locking gate 90 (Figure 3A).
Member 92 includes a camming extremity 92a for engagement with gate 90 to move the gate into the second release position shown in Figures 9 and 9A upon movement of guide pin 29 into its second forward most advanced position shown in Figure 9 wherein the forward extremity of the guide pin is received within bore 21a formed in stationary jaw 21.
As best seen by referring to Figures 3A, 8 and 9, release segment 92 as well as pin 29 are connected to a slide member 94 which is slidably movable relative to frame 14 in the manner shown by the arrow in Figure 8. With this construction, when slide member 94 is in its rearward most position adjacent handle portion 36 release segment 92 fully extends into handle 36 (Figure 1). However, as slide member 94 is moved forwardly in the manner indicated in Figure 8, segment 92 will be withdrawn from handle portion 36 in a manner such that the camming segment 92 moves forwardly in a direction toward locking gate 90. When slide member 94 is moved to its furthermost forward position (as shown in Figure 9), segment 92 will be substantially entirely withdrawn from handle 36 and camming extremity 92a will move into engagement with locking gate 92 so as to urge it downwardly into a recess 36a formed proximate the forward end of handle portion 36 in the direction of the arrow shown in Figure 9A.
it is to be understood that when the elongated release segment 92 is in this forward most position, guide pin 29 is also in its forward most position with the forward extremity of the pin extending into bore 21a of fixed jaw 21. When, and only when, the components are in the position indicated in Figure 9, will the operating bar 56 be free to move into engagement with pusher members 28 in a manner to urge them into driving engagement with the staples contained within staple cartridge 27.
Referring particularly to Figures 6, 6A, 6B, 9 and 9A, it is to be observed that, operating or T-bar member 56, is provided with an elongated slot 96 within which gate 90 can travel. Slot 96 terminates at its forward end in a shoulder 96a and in its rearward end in a shoulder 96b. Prior to gate 94 being cammed downwardly into the release position shown in Figure 9A, forward movement of the T-bar 56 is limited by gate 90 moving into blocking engagement with locking surface or shoulder 96b. Only after the locking gate has been moved into its release position by camming extremity 92a moving into the position shown in Figures 9 and 9A will further forward travel of operating bar 56 be possible. Consequently, with this novel construction, it is readily apparent that unless and until guide pin 29 is advanced fully into its second position, locking gate 90 will limit the forward travel of the operating member 56 and prevent its advancement into the staple firing positiori shown in Figure 10.
So long as a spent cartridge is deployed within the instrument, the first locking means of the invention will prevent advancement of' guide pin 29 into its second, forward most position. When this is the case, the second locking means, which includes gate 90, will positively prevent advancement of operating bar 56 into the staple firing configur=ation. This cooperative interaction between the first and second locking means of the invention provides an indication to the surgeon that a spent cartridge is deployed within the instrument and that the spent cartridge must be replaced with a fresh cartridge before proceeding with its use.
It is to be observed that, although locking gate 90 effectively prevents movement of operating bar 56 into the staple firing position shown in Figure 10, the novel design of 0 the second locking means (see Figures 6, 6A and 6B) does not prevent forward movement of members 30 and 32. More particularly, as shown in Figures 6, 6A and 6B, members 30 and 32 are provided with elongated slots 30a and 33a which permit advancement of these members past gate 90 into a forward approximated position. Accordingly, the jaws of the instrument can be approximated even though guide pin 29 is not in its forward most position. However, for the reasons discussed in the preceding paragraphs, the surgeon is positively prevented from moving the actuating ':C-bar 56 forwardly to the position shown in Figure 9. only when pin 29 is fully seated thereby permitting release segments 92 to cam gate 90 downwardly in the manner shown in Figure 9A, will the surgeon be able to advance the operating T-bar 56 into the staple driving configuration shown in Figure 10.
Turning next to Figures 16 through 19, an alternate form of the first locking means of the invention is there illustrated. In this embodiment of the invention, the second locking means comprises a riovel guide pin interference means for blocking the advancement of the guide pin. This means is here provided as a novel mechanism 100 which forms a part of a modified staple cartridge assembly 102 having a body portion 102a which is provided with a pin receiving bore 102b.
Mechanism 100 includes a pin interference member 104 having a cover portion 104a an integrally formed leg-like locking portion, or member 104b. Member 104 is movable from the first retracted position shown in Figure 16 to the second pin interfering position shown in Figure 18 wherein cover portion 104 covers the pin receiving bore 102b. Also forming a part of the interference mechanism of this form of the invention is a biasing means for continuously urging interference member 104 toward the second interfering position shown in Figure 18. The biasing means is here provided in the form of a generally U-2 if8 '13 10 shaped spring 108, a first leg 108a of which is connected to staple cartridge 102 and a second leg 108b of which is connected to member 104 in 'the manner shown in Figure 16.
With the apparatus in the configuration shown in Figure 16, leg 104b engages an edge 28a formed on the outwardly protruding pusher member 28 (see also Figure 17). Referring to Figures 18 and 19, it is to be observed that, during the staple firing step in which the pusher member 28 is moved inwardly of cartridge 102, edge 28a of the pusher member will move inwardly out of the way of locking segment 104b thereby permitting spring 108 to move the interference member from the first position shown in Figure 16 to the second interfering positiori shown in Figure 18. In this pin interfering position, advancement of the guide pin, which is shown in Figure 19 by the phantom lines, will be blocked by cover portion 104a of the interference member thereby preventing the guide pin from entering bore 102b and advancing into its second forward most position in engagement. with stationary jaw 21.
When the alternate form of first locking means of the invention is used in connection wi.th an instrument which embodies the previously described, second locking means of the invention, the inability of the surgeon to advance guide pin 29 into its forward most second position will also prevent the full advancement of release segment 92 of the second locking means. Accordingly, locking gate 90 will remain in an upraised locking position blocking forward movement of operating T-bar 56 into a staple firing configuration. Once again, this cooperative interaction between the first and second locking means of the invention effectively disables the instrument unless and until a fresh staple cartridge is deployed within the device so that the guide pin 29 can be advanced by the surgeon into its second fully advanced position.
Turning to Figures 20 and 21 still, another form of the 2 ii 8 first locking means of the invention is there illustrated.
This locking means is similar in many respects to the form shown in Figures 16 through 19 and like numerals are used to identify like components. In this embodiment of the invention, the first locking means also comprises a novel guide pin interference means for blocking the advancement of the guide pin. This means, like the means shown in Figures 16 through 19 comprises mechanism 100 which forms a part of an alternate type of modified staple cartridge assembly 111 having a body portion 111a which is provided with a guide pin receiving bore 1l1b.
Modified staple cartridge 111 is of a character adapted for use with a surgical stapler in which the pusher members that engage the staples form a part of the operating assembly of the instrument rather than a part of the staple cartridge.
As before, mechanism 100 includes a guide pin interference member 104 having a cover portion 104a, an integrally formed leg-like locking portion, or member 104b. Member 104 is movable from the first retracted position shown in the solid lines of Figure 20 to the second, pin interfering position shown in the phantom lines of Figure 20 wherein cover portion 104a covers the pin receiving bore 111b. Also forming a part of the interference mechanism of this form of the invention is a biasing for continuously urging interference member 104 toward the second interfering position shown in the phantom lines in Figure 20. The biasing means is here provided in the form of a generally U-shaped spring 108, a first leg 108a of which is connected to staple cartridge 111 and a second leg 108b of which is connected to member 104 in the manner shown in Figure 20.
With the apparatus in the configuration shown in the solid lines of Figure 20, leg 104b engages an edge 113a formed on an outwardly protruding locking pin or member 113 which is telescopically receivable into a second bore 114 formed in body portion l11a. During the staple firing step in which the operating bar is advanced, the pusher assembly that is connected to the operating bar is moved inwardly of cartridge 111. As the pusher assembly moves inwardly, it will contact member 113 causing it to move inwardly out of the way of locking segment 104b in the manner shown by the arrow and the phantom lines of Figure 21. With member 113 out of the way, spring 108 will move the interference member 104 from the first position shown by the solid lines in Figure 20 to the second interfering position shown by the phantom lines in Figure 20.
In this guide pin interfering position, advancement of the guide pin, which is stiown in Figure 21 by the phantom lines, will be blocked by cover portion 104a of the interference member thereby preventing the guide pin from entering bore lllb and advancing into .its second forward most position in engagement with stationary jaw 21.
When this latest form of first locking means of the invention is used in connection with an instrument which embodies the previously described, second locking means of the invention, the inability of the surgeon to advance guide pin 29 into its forward most second position will also prevent the full advancement of release segment 92 of the second locking means. Accordingly, locking gate 90 will remain in an upraised locking position (see Figure 6) blocking forward movement of operating T-bar 56 into a staple firing configuration. As before, this cooperative interaction between the first and second locking means of the invention effectively disables the instrument unless and until a fresh staple cartridge is deployed within the device so that the guide pin 29 can be advanced by the surgeon into its second fully advanced position.
Referring next to Figures 22, 22A, 22B, 22C, 23, and 23A, an alternate form of the second locking means of the invention is there illustrated. This form of second locking means is somewhat similar to that shown in Figures 1 through 10 and like numbers are used to identify like components. This second locking means uniquely functions to selectively disable the operating linkage of the apparatus and here comprises a guide pin assembly which, as shown in Figure 22C, is similar in many respects to that shown in Figure 3A. However, this modified assembly includes an elongated linkage blocking means or segment 122 which is connected to a slide member 124 and is slidably receivable within handle portion 36. Segment 122 includes a blocking extremity 122a for blocking engagement with linkage 34a. More particularly, following staple firing and upon movement of guide pin 29 into the first retracted position shown in Figure 23, blocking extremity 122a moves to a location below linkage assembly 34a preventing movement thereof into the overcenter, locked position shown in Figure 22.
Referring particularly to Figures 22, 22A and 22C, it can be seen that linkage blocking segment 122 as well as pin 29 are connected to a slide member 124 which, as before, is slidably movable relative to frame 14 from a forward guide pin advanced position to the guide pin retracted position shown in Figure 22. As indicated in Figures 23 and 23A, when slide member 124 is moved into its rearward most position linkage blocking segment 122 extends into handle 36 and extremity 122A engages the linkage assembly and, with the aid of spring 46 (Figure 4), will urge the assembly into its upwardly extending starting position. This being the case, the release means or release assembly 66 present in the earlier described embodiment is not here required.
So long as segment 122 is in the rearmost position shown in Figure 23, linkage assembly 34a cannot be moved in the overcenter, locked position. However, if slide member 124 is moved forwardly to its fully advanced position, wherein guide pin 29 engages stationary jaw 21, segment 122 will be withdrawn from handle portion 36 in a manner such that extremity 122a clears the linkage assembly and no longer blocks downward movement of the assembly into the overcenter locking position thereby permitting approximation of jaws 21 and 26. However, if the first locking means of the invention, as for example that shown in Figures 11 through 15, prevents movement of guide pin 29 to its fully advanced second position, segment 122 will block normal downward movement of the linkage assembly so that the instrument can neither be locked in the approximated position nor fired. Stated another way, when, and only when, the components are in the position indicated in Figure 22, can the instrument be locked in the approximated position, and upon the subsequent operation of the handle assembly, will the operatirig bar 56 be free to move into engagement with pusher members 28 in a manner to urge them into driving engagement with the staples contained within staple cartridge 27.
Turning now to Figures 24 through 26, still another form of the second locking means of the invention is there illustrated. This form of second locking means is somewhat similar to that just described and like numbers are used to identify like components. This latest form of second locking means also functions to selectively disable the operating linkage 34a of the apparatus and here comprises a guide pin assembly which is similar to that shown in Figure 22C.
However, this assembly includes not only an elongated, rearwardly extending segment 127, which is connected to a slide member 129, but also includes a novel shuttle member 131. (See also Figures 24B and 24D) . In this latest form of the invention, it is this shuttle member that is selectively movable into blocking engagement with linkage 34a. More particularly, following staple firing and upon movement of Q 2~~ ~~ ~~ 1 guide pin 29 into the first retracted position shown in Figure 24, segment 127 engages and slidably moves shuttle member 131 to the location shown in Figure 24 where it is directly below linkage assembly 34a thereby preventing movement of the assembly into the overcenter locked position shown in Figure 26.
Referring particularly to Figures 24A and 24B, it is to be noted that segment 127 as well as pin 29 are connected to a slide member 129 which, as before, is slidably movable relative to frame 14 fr=om a forward guide pin advanced position shown in Figure 26 to the guide pin retracted position shown in Figure 24. When slide member 129 is moved into its rearward most position closely adjacent to handle portion 36, (Figure 24A) segment 127 extends into handle 36 to its maximum extent and urges shuttle 131 to its rearward most, first position shown in Figure 24A. However, because of the cooperative interaction between segment 127 and shuttle 131, when the slide member 129, along with guide pin 29, is moved to the forward most second position shown in Figures 26 and 26A, shuttle 131 is moved forwardly by segment 127 to the non-interfering second position shown in Figure 26 wherein the linkage can move into a recess 132 formed in the shuttle. In this regard it is to be noted that segment 127 includes an elongated dwell slot 133 (Figure 24B) within which an engagement pin 135 provided on shuttle 131 is slidably received. With this construction, when, and only when, guide pin 29 is in its forward most position will the end wall 133a of slot. 133 engage engagement pin 135 and urge the shuttle forwardly to the position shown in Figure 26. It should be noted that this feature allows the surgeon who has completed the firing-reopening-pin withdrawal cycle to use the stapler as a clamp. In this form, the instrument could function as an additional clamp, spring-biased in the open position, unless the surgeon squeezes the lever against the handle.
As best seen in Figure 25, as guide pin 29 is initially advanced a partial distance toward stationary jaw 21, shoulder 133a moves along a slot 131a formed in shuttle 131. However, in this position the shuttle itself remains in a stationary linkage blocking position so that an upstanding shoulder 131c formed on the shuttle prevents movement of linkage 34a into the overcenter position. Only after end wall 133a engages pin 135 will shuttle 131 start to move forwardly to the position shown in Figure 26 so that the linkage assembly can move into an overcenter position.
It is apparent that when this latest form of second locking means is used with. one of the first locking means previously described herein, such as for example, that shown in Figures 11 through 15, the existence of a spent cartridge in the instrument will once again prevent full advancement of the guide pin which, in turn, will prevent movement of shuttle 131 into the non-interfering positiori shown on Figure 26.
Therefore, until the spent staple cartridge is replaced with a fresh cartridge, the instrument will remain inoperable.
Similarly, after the instrument is fired and the guide pin retracted to remove the stapled tissue, shuttle 131 will block complete downward movement of the linkage assembly. To render the instrument operable, the spent staple cartridge must be replaced with a fresh cartridge to enable complete forward movement of the guide pin and advancement of the shuttle into a non-interfering forward position.
Having now described the invention in detail in accordance with the requirement of the patent statutes, those skilled in this art will have no difficulty in making changes and modifications in the individual parts or their relative assembly in order to meet specific requirements or conditions.
Such changes and modifications may be made without departing from the scope and spirit of the invention, as set forth in the following claims.

Referring to the drawings and particularly to Figures 1 through 3, one form of the apparatus of the invention for simultaneously emplacing a plurality of surgical staples into tissues and organs is there shown and generally designated by the numeral 12. The apparatus comprises an elongated supporting frame 14 having first and second longitudinally extending spaced walls 16 and 18 defining an interior space 20 (Figure 3). Forming an integral part of frame 14 is a stationary jaw assembly 21 which includes an anvil portion 22 having a staple-engaging face 24.
Slidably movable within frame 14 from a first retracted position to a second forward position is a movable jaw assembly 26. Removably deployed within movable jaw assembly 26 is a staple cartridge 27 (Figure 7) which contains a plurality of surgical staplers that are adapted to pass through the tissue to be stapled and then crimped against face 24 of anvil 22 in a manner. presently to be described.
As indicated in Figure 7, a pusher member 28 is associated with cartridge 27 for movement relative to the cartridge housing 27a between a first extended position as shown in Figures 7 and 9 to a second stapled fir.ed position shown in Figure 10. During the firing step, pusher member 28 engages the staples contained within the staple cartridge and drives them forwardly into pressural engagement with face 24 of anvil portion 22. As the staples are simultaneously driven from the staple cartridge, they will engage the anvil face and typically crimp into a crimped shaped roughly corresponding to the shape A'A .2 1 of the letter "B". As the staples are appropriately crimped, they will, of course, join together the layers of tissue or organ "T" between face 24 of the anvil and the forward face of the staple cartridge.
In operating the instrument, when the staple cartridge, along with its cooperating pusher member, is disposed in the spaced-apart relationship with anvil 22 as shown in Figure 7, tissue or human organ can be placed in the open space between the staple cartridge and face 24 of the anvil. After the tissue has been appropriately positioned between the staple cartridge and the anvil, guide means, which here includes an elongated retractable guide pin 29, is moved forwardly to the second advanced position shown by the phantom lines in Figure 7. Next, using the approximation means of the invention, movable jaw assembly 26 along with staple cartridge 27, is moved forwardly of the apparatus to a location where it is closely adjacent face 24 of anvil 22 (see Figure 9). During travel of jaw assembly 26 and staple cartridge 27, guide pin 29 maintains proper alignment of the components and also functions to retain the tissue "T" in position between jaw assemblies 21 and 26.
As can best be seen by referring to Figures 1, 2, and 3, movable jaw assembly 26 includes a pair of spaced-apart approximation members 30 and 32, the forward portions of which define the cartridge receiving portion 26a (Figure 2). Members and 32 are disposed between side walls 16 and 18 and, in a manner presently to be described, are slidably movable with respect thereto from a first retracted position shown in Figures 2 and 7 to a forward, approximated position shown in 30 Figure 9.
In the embodiment of the invention shown in Figures 1 through 10, the means for moving the movable jaw assembly toward the stationary jaw includes a handle assembly 34 which comprises a fixed handle portion 36 and a movable handle portion, or actuating lever 37, which is pivotally connected to fixed handle portion 36 in the manner best seen in Figures 1 and 4. Additionally, these approximation means further include an operating linkage 34a made up of pivotally interconnected first and second operating links 38 and 40 (Figure 4). The first end 38a of link 38 is pivotally interconnected both with frame 14 and with a third link member 42 by a pivot pin 39. The second end 38b of link 38 is pivotal:ly connected to link 40 proximate its first end 40a by a pivot pin 39a. The second end 40b of link 40 is operably associated with members 30 and 32 and moves these members forwardly as the linkage is moved into the collapsed, overcenter configuration shown in Figures 9 and 10. With this construction, when actuating lever 37 is moved from the first position shown in Figure 1 to the second position shown in phantom lines in Figure 9, linkage assembly 34a will be moved by lever 37 from the extended position shown in Figure 1 to the collapsed position shown in Figure 9. As linkage 34a moves into this collapsed, overcenter position, members 30 and 32 are urged forwardly to the position shown in Figure 9. A first biasing means, shown here as an enlongated coil spring 45 (Figure 4) yieldably resists depression of lever 37. Simi-larly, a second biasing means, here provided as a torsion spring 46, yieldably resists movement of linkage assembly 34a from the upraised position shown in Figure 1 to the collapsed or closed position shown in Figure 9. As will be discussed in the paragraphs which follow, spring 46 tends to automatically return linkage 34a to the upraised position when it is moved by a novel release means from the downward, overcenter position shown in Figure 9 toward the open, upstanding position shown in Figure 1.
It is to be noted that movement of the generally "T"
1 685 1 A, 1 1) shaped members 30 and 32, which are slidably received within spaced-apart walls 16 and 18 of frame 14, is yieldably resisted by a third biasing means which comprises an elongated coil spring 47 having an end 47a connected to the supporting frame and an end 47b connected to the members 30 and 32 (Figure 4).
Formed proximate the forward end of members 30 and 32 is the previously identified movable jaw assembly 26 which removably receives staple cartridge 27. With this construction, it is apparent that the forward movement of members 30 and 32 caused by the initial closing of lever 37 will result in the staple cartridge moving into the approxi-mated position wherein it is located adjacent anvil 22 (Figure 9). The device will remain in this approximated position until it is x=eleased by the release means of the invention in a manner presently to be described.
Following the approximation step, the staples can be driven through the tissue "T" and into pressural engagement with the anvil 22 by the operating means of the invention. In the form of the invention shown in the drawings, the operating means comprises a generally "T" shaped operating bar 56 which is slidably movable between members 30 and 32 from a first retracted position shown in Figures 2 and 9 to a second staple fired position shown in Figure 10. The operating means also comprises an operating member or link 52 which is pivotally connected to handle portion 37 for pivotal movement between first and second positions. As best seen in Figure 10, operating link 52 includes an end portion 52a which is movable into engagement with operating bar 56 following movement of lever 37 to its third retracted position shown by the phantom lines in Figure 10.
As can be observed by also referring to Figure 1, prior to the approximation step, operating link 52 is maintained in its first upraised position by the rearwardly positioned 4e :
A
members 30 and 32. However, upon movement of these members forwardly of the apparatus into the approximated position shown in Figure 9, and upon movement of handle portion 37 from its second downward position shown by the phantom lines in Figure 9 to its third upward position shown by the phantom lines in Figure 10, member 52 will pivot downwardly due to the urging of a fourth biasing means shown here as a torsion spring 56 (Figure 4). With member 52 in this downward position, movement of handle 37 into the fourth downward position shown by the solid lines in Figure 10 will cause end 52a of member 52 to engage the T-shaped bar 56 and cause it to move forwardly between member 30 and 32 from the position shown in Figure 9 to the forward staple fired position shown in Figure 10. As the T-shaped bar moves forwardly toward staple cartridge 27, it will engage the pusher members and force the staples from the cartridge through the tissue to be coapted and into pressural engagement with anvil 22. In the prior art staplers, spring 45 would then tend to urge lever 28 into its normal upraised position. Visual. observation of the device after firing would, therefore, require that the surgeon both remember to, and have the opportunity to, observe whether carriage pusher members 28 have disappeared from the field of view created by a hole XX (Figure 10) . If the pusher members are not visible, the surgeon could conclude that the cartridge had been fired. On the other hand, if the pusher members are still visible, the surgeon could conclude that the cartridge has not yet been fired. While this is better than no feedback at all, it is not ideally suited for the busy environment of the operatirig room nor to the lack of visibility associated with many procedures in which the stapler is used.
After the staples have been fired, the release means of the device is used to return the linkage assembly to its starting position. The release means shown in Figures 1 0 2 18' 1 '5 10 through 10 comprises a manually operated release pin assembly 66 which is movable within a slot 67 formed in the handle portion of the apparatus from a first downward position to a second upward release position (Figures 5 and 9). The release pin assembly 66 here includes a knob portion 68 which is interconnected with a shaft portion 70 that extends through and is guided by slot 67. The inboard end of shaft 70 is interconnected with linkage assembly 34a so that an upward movement exerted on knob 68 will move the linkage assembly from the downward, overcenter position shown in Figure 9 toward the upward, starting position shown in Figure 1. As knob 68 is moved upwardly, the linkage assembly will rapidly snap into the upward starting position as a result of the action of torsion spring 46.
Forming an important aspect of the present invention is the provision of cooperating, interrelated first and second locking means which function to effectively disable the instrument unless a fresh staple cartridge is in position within the movable jaw of the device. Tn the present form of the invention, the first lockout locking means functions to engage guide pin 28 in a manner to positively prevent its advancement toward the second advanced position shown by the phantom lines of Figure 7 wherein it is seated within bore 21a provided in stationary jaw 21. In a manner presently to be described, this first locking means uniquely cooperates with the second lockout locking means to prevent a staple firing advancement of operating bar 56 unless a fresh staple cartridge is in place within the instrument and the guide pin is fully advanced into its second advanced position. This unique backup feature provides a clear and unmistakable signal to the surgeon as to the condition of the cartridge that is in place within the instrument.
Turning to Figures 11 through 15 one form of the first locking means of the invention is there illustrated. This first locking means here comprises a novel locking mechanism 75 of the character best seen in Figures 11 and 15. Mechanism 75 is carried by movable jaw 26 and comprises a uniquely channelled platform 76 which is connected to movable jaw 26.
Carried by platform 76 is a first member 78, which includes a generally triangularly shaped pusher engaging extremity 80, and a second cooperating member 82 (Figure 5). Member 82 includes a yoke-like locking extremity 82a which, in a manner presently to be described, is receivable within a guideway 84 formed in pin 29 and is movable therewithin into locking engagement with longitudinally spaced apart locking shoulders formed at the opposite ends of the guideway (Figure 14). As best seen in Figures 14 and 14a, guideway 84 is formed by milling or otherwise forming the opposing sides of pin 29 in a manner to provide longitudinally extending, generally flat surfaces which define the guideway. Formed at one extremity of the guideway 84 is a shoulder 85 and formed at the opposite end thereof is a shoulder 86 (Figure 14).
Also comprising a part of the locking mechanism of this form of the invention is a biasing means for urging first member 78 outwardly of platform 76 and into engagement with pusher members 28a in the manner shown in Figure 11. The biasing means also functions to simultaneously urge second locking member 82 upwardly into engagement with guide pin 29 in the manner shown in Figure 11. In the embodiment of the invention shown in the drawings, the biasing means is provided in the form of a clip-type spring 89, the configuration of which is best seen by referring to Figure 15. When spring 89 is in position within block 76, leg 89a of the spring engages the inboard end 78a of member 78 and urges the member outwardly of the housing in a direction toward the pusher members 28.
In similar fashion, leg 89b of spring 89 engages the inboard end 82b of member 82 and tends to urge the member upwardly into pressural engagement with guide pin 29. Member 78 is provided with a generally V-shaped cutout portion 78c which lockably engages a fulcrum-like member 82c provided on member 82 when member 78 is moved by spring 89 into the extended position best seen in Figure 14.
Turning once again to Figure 11, it can be observed that with the movable jaw in the approximated position and with pusher members 28 extending rearwardly from the fresh staple cartridge 27 that is deployed within the movable jaw, forward movement of locking member 78, due to the urging of spring 89, will be prevented by the rearwardly extending pusher members 28. Similarly, in this configuration, the second locking pin 82 will be retained in its retracted position within block 76 by the fulcrum-like protuberance 82c of member 82 engaging member 78 in the manner shown in Figures 11 and 12A. However, upon operating bar 56 moving forwardly in a manner shown in Figure 13 to urge pusher members 26 into firing engagement with the staples disposed within staple cartridge 27, the pusher members will no longer impede forward movement of locking member 78. Accordingly, leg 89a of spring 89 will urge member 78 forwardly of the platform 76 in the direction of the arrow in Figure 13. As member 78 moves forwardly, or to the right as viewed in Figure 13, V-shaped slot 76c will move into register with the fulcrum-like protuberance 82a provided on member 82 thereby causing spring leg 84b to urge member 82 upwardly into the position shown in Figure 13 wherein yoke-shaped end portion 82a engages the outer cylindrical surface of guide pin 29. Following the staple firing step and during the subsequent retraction of guide pin 29, the yoke-shaped extremity 82a of member 82 will move into the guideway 84 formed on pin 29 and then into engagement with shoulder 85 in the manner shown in Figure 14.
~ ~ ~ a 11 ~a~,~ 10 If the surgeon attempts to advance the guide pin without replacing the spent cartridge, extremity 82a of locking pin 82 will move into engagement with shoulder 86 thereby blocking further advancement of the guide pin and providing a tactile sensation to the surgeon. In this regard, it is to be noted that the length of guideway 84 is such that the guide pin cannot be fully advanced to its forward most second position so long as locking pin 82 is in the extended position. Thus the tactile indication given to the surgeon as pin 82 engages shoulder 86 advises the surgeon that forward travel of the pin is blocked thereby providing a positive input that a spent cartridge is in place within the instrument.
Upon insertion of a fresh cartridge into the movable jaw assembly of the instrument, the extended pusher members of the fresh cartridge will move locking pin 78 to the left as viewed in Figure 14 against the urging of leg 89a of spring 89. This rearward movement of member 78 will also cause member 82 to be cammed downwardly against the urging of leg 89b of spring 89 so that the locking mechanism will be returned to the starting configuration shown in Figures 11 and 12A. With the component parts in this position and with blocking member 82 in its retracted location, it is apparent that guide pin 29 can be freely moved forwardly of the device and into its fully advanced second position. This freedom of movement of guide pin 29 into its fully advanced second position indicates to the surgeon that a fresh cartridge is in place within the instrument and that use of the instrument can safely proceed.
Referring particularly to Figures 1, 3A, and 6, one form of the second locking means of the invention is there illustrated and can be seen to comprise a locking gate 90 which is carried by handle portion 36 for movement between a first locking position shown in Figure 6 and a second release position shown in Figure 9B. In the present form of the 11 p i "~10 invention, the release means comprises an elongated release segment or member 92 which is slidably receivable within a central aperture 90a formed in locking gate 90 (Figure 3A).
Member 92 includes a camming extremity 92a for engagement with gate 90 to move the gate into the second release position shown in Figures 9 and 9A upon movement of guide pin 29 into its second forward most advanced position shown in Figure 9 wherein the forward extremity of the guide pin is received within bore 21a formed in stationary jaw 21.
As best seen by referring to Figures 3A, 8 and 9, release segment 92 as well as pin 29 are connected to a slide member 94 which is slidably movable relative to frame 14 in the manner shown by the arrow in Figure 8. With this construction, when slide member 94 is in its rearward most position adjacent handle portion 36 release segment 92 fully extends into handle 36 (Figure 1). However, as slide member 94 is moved forwardly in the manner indicated in Figure 8, segment 92 will be withdrawn from handle portion 36 in a manner such that the camming segment 92 moves forwardly in a direction toward locking gate 90. When slide member 94 is moved to its furthermost forward position (as shown in Figure 9), segment 92 will be substantially entirely withdrawn from handle 36 and camming extremity 92a will move into engagement with locking gate 92 so as to urge it downwardly into a recess 36a formed proximate the forward end of handle portion 36 in the direction of the arrow shown in Figure 9A.
it is to be understood that when the elongated release segment 92 is in this forward most position, guide pin 29 is also in its forward most position with the forward extremity of the pin extending into bore 21a of fixed jaw 21. When, and only when, the components are in the position indicated in Figure 9, will the operating bar 56 be free to move into engagement with pusher members 28 in a manner to urge them into driving engagement with the staples contained within staple cartridge 27.
Referring particularly to Figures 6, 6A, 6B, 9 and 9A, it is to be observed that, operating or T-bar member 56, is provided with an elongated slot 96 within which gate 90 can travel. Slot 96 terminates at its forward end in a shoulder 96a and in its rearward end in a shoulder 96b. Prior to gate 94 being cammed downwardly into the release position shown in Figure 9A, forward movement of the T-bar 56 is limited by gate 90 moving into blocking engagement with locking surface or shoulder 96b. Only after the locking gate has been moved into its release position by camming extremity 92a moving into the position shown in Figures 9 and 9A will further forward travel of operating bar 56 be possible. Consequently, with this novel construction, it is readily apparent that unless and until guide pin 29 is advanced fully into its second position, locking gate 90 will limit the forward travel of the operating member 56 and prevent its advancement into the staple firing positiori shown in Figure 10.
So long as a spent cartridge is deployed within the instrument, the first locking means of the invention will prevent advancement of' guide pin 29 into its second, forward most position. When this is the case, the second locking means, which includes gate 90, will positively prevent advancement of operating bar 56 into the staple firing configur=ation. This cooperative interaction between the first and second locking means of the invention provides an indication to the surgeon that a spent cartridge is deployed within the instrument and that the spent cartridge must be replaced with a fresh cartridge before proceeding with its use.
It is to be observed that, although locking gate 90 effectively prevents movement of operating bar 56 into the staple firing position shown in Figure 10, the novel design of 0 the second locking means (see Figures 6, 6A and 6B) does not prevent forward movement of members 30 and 32. More particularly, as shown in Figures 6, 6A and 6B, members 30 and 32 are provided with elongated slots 30a and 33a which permit advancement of these members past gate 90 into a forward approximated position. Accordingly, the jaws of the instrument can be approximated even though guide pin 29 is not in its forward most position. However, for the reasons discussed in the preceding paragraphs, the surgeon is positively prevented from moving the actuating ':C-bar 56 forwardly to the position shown in Figure 9. only when pin 29 is fully seated thereby permitting release segments 92 to cam gate 90 downwardly in the manner shown in Figure 9A, will the surgeon be able to advance the operating T-bar 56 into the staple driving configuration shown in Figure 10.
Turning next to Figures 16 through 19, an alternate form of the first locking means of the invention is there illustrated. In this embodiment of the invention, the second locking means comprises a riovel guide pin interference means for blocking the advancement of the guide pin. This means is here provided as a novel mechanism 100 which forms a part of a modified staple cartridge assembly 102 having a body portion 102a which is provided with a pin receiving bore 102b.
Mechanism 100 includes a pin interference member 104 having a cover portion 104a an integrally formed leg-like locking portion, or member 104b. Member 104 is movable from the first retracted position shown in Figure 16 to the second pin interfering position shown in Figure 18 wherein cover portion 104 covers the pin receiving bore 102b. Also forming a part of the interference mechanism of this form of the invention is a biasing means for continuously urging interference member 104 toward the second interfering position shown in Figure 18. The biasing means is here provided in the form of a generally U-2 if8 '13 10 shaped spring 108, a first leg 108a of which is connected to staple cartridge 102 and a second leg 108b of which is connected to member 104 in 'the manner shown in Figure 16.
With the apparatus in the configuration shown in Figure 16, leg 104b engages an edge 28a formed on the outwardly protruding pusher member 28 (see also Figure 17). Referring to Figures 18 and 19, it is to be observed that, during the staple firing step in which the pusher member 28 is moved inwardly of cartridge 102, edge 28a of the pusher member will move inwardly out of the way of locking segment 104b thereby permitting spring 108 to move the interference member from the first position shown in Figure 16 to the second interfering positiori shown in Figure 18. In this pin interfering position, advancement of the guide pin, which is shown in Figure 19 by the phantom lines, will be blocked by cover portion 104a of the interference member thereby preventing the guide pin from entering bore 102b and advancing into its second forward most position in engagement. with stationary jaw 21.
When the alternate form of first locking means of the invention is used in connection wi.th an instrument which embodies the previously described, second locking means of the invention, the inability of the surgeon to advance guide pin 29 into its forward most second position will also prevent the full advancement of release segment 92 of the second locking means. Accordingly, locking gate 90 will remain in an upraised locking position blocking forward movement of operating T-bar 56 into a staple firing configuration. Once again, this cooperative interaction between the first and second locking means of the invention effectively disables the instrument unless and until a fresh staple cartridge is deployed within the device so that the guide pin 29 can be advanced by the surgeon into its second fully advanced position.
Turning to Figures 20 and 21 still, another form of the 2 ii 8 first locking means of the invention is there illustrated.
This locking means is similar in many respects to the form shown in Figures 16 through 19 and like numerals are used to identify like components. In this embodiment of the invention, the first locking means also comprises a novel guide pin interference means for blocking the advancement of the guide pin. This means, like the means shown in Figures 16 through 19 comprises mechanism 100 which forms a part of an alternate type of modified staple cartridge assembly 111 having a body portion 111a which is provided with a guide pin receiving bore 1l1b.
Modified staple cartridge 111 is of a character adapted for use with a surgical stapler in which the pusher members that engage the staples form a part of the operating assembly of the instrument rather than a part of the staple cartridge.
As before, mechanism 100 includes a guide pin interference member 104 having a cover portion 104a, an integrally formed leg-like locking portion, or member 104b. Member 104 is movable from the first retracted position shown in the solid lines of Figure 20 to the second, pin interfering position shown in the phantom lines of Figure 20 wherein cover portion 104a covers the pin receiving bore 111b. Also forming a part of the interference mechanism of this form of the invention is a biasing for continuously urging interference member 104 toward the second interfering position shown in the phantom lines in Figure 20. The biasing means is here provided in the form of a generally U-shaped spring 108, a first leg 108a of which is connected to staple cartridge 111 and a second leg 108b of which is connected to member 104 in the manner shown in Figure 20.
With the apparatus in the configuration shown in the solid lines of Figure 20, leg 104b engages an edge 113a formed on an outwardly protruding locking pin or member 113 which is telescopically receivable into a second bore 114 formed in body portion l11a. During the staple firing step in which the operating bar is advanced, the pusher assembly that is connected to the operating bar is moved inwardly of cartridge 111. As the pusher assembly moves inwardly, it will contact member 113 causing it to move inwardly out of the way of locking segment 104b in the manner shown by the arrow and the phantom lines of Figure 21. With member 113 out of the way, spring 108 will move the interference member 104 from the first position shown by the solid lines in Figure 20 to the second interfering position shown by the phantom lines in Figure 20.
In this guide pin interfering position, advancement of the guide pin, which is stiown in Figure 21 by the phantom lines, will be blocked by cover portion 104a of the interference member thereby preventing the guide pin from entering bore lllb and advancing into .its second forward most position in engagement with stationary jaw 21.
When this latest form of first locking means of the invention is used in connection with an instrument which embodies the previously described, second locking means of the invention, the inability of the surgeon to advance guide pin 29 into its forward most second position will also prevent the full advancement of release segment 92 of the second locking means. Accordingly, locking gate 90 will remain in an upraised locking position (see Figure 6) blocking forward movement of operating T-bar 56 into a staple firing configuration. As before, this cooperative interaction between the first and second locking means of the invention effectively disables the instrument unless and until a fresh staple cartridge is deployed within the device so that the guide pin 29 can be advanced by the surgeon into its second fully advanced position.
Referring next to Figures 22, 22A, 22B, 22C, 23, and 23A, an alternate form of the second locking means of the invention is there illustrated. This form of second locking means is somewhat similar to that shown in Figures 1 through 10 and like numbers are used to identify like components. This second locking means uniquely functions to selectively disable the operating linkage of the apparatus and here comprises a guide pin assembly which, as shown in Figure 22C, is similar in many respects to that shown in Figure 3A. However, this modified assembly includes an elongated linkage blocking means or segment 122 which is connected to a slide member 124 and is slidably receivable within handle portion 36. Segment 122 includes a blocking extremity 122a for blocking engagement with linkage 34a. More particularly, following staple firing and upon movement of guide pin 29 into the first retracted position shown in Figure 23, blocking extremity 122a moves to a location below linkage assembly 34a preventing movement thereof into the overcenter, locked position shown in Figure 22.
Referring particularly to Figures 22, 22A and 22C, it can be seen that linkage blocking segment 122 as well as pin 29 are connected to a slide member 124 which, as before, is slidably movable relative to frame 14 from a forward guide pin advanced position to the guide pin retracted position shown in Figure 22. As indicated in Figures 23 and 23A, when slide member 124 is moved into its rearward most position linkage blocking segment 122 extends into handle 36 and extremity 122A engages the linkage assembly and, with the aid of spring 46 (Figure 4), will urge the assembly into its upwardly extending starting position. This being the case, the release means or release assembly 66 present in the earlier described embodiment is not here required.
So long as segment 122 is in the rearmost position shown in Figure 23, linkage assembly 34a cannot be moved in the overcenter, locked position. However, if slide member 124 is moved forwardly to its fully advanced position, wherein guide pin 29 engages stationary jaw 21, segment 122 will be withdrawn from handle portion 36 in a manner such that extremity 122a clears the linkage assembly and no longer blocks downward movement of the assembly into the overcenter locking position thereby permitting approximation of jaws 21 and 26. However, if the first locking means of the invention, as for example that shown in Figures 11 through 15, prevents movement of guide pin 29 to its fully advanced second position, segment 122 will block normal downward movement of the linkage assembly so that the instrument can neither be locked in the approximated position nor fired. Stated another way, when, and only when, the components are in the position indicated in Figure 22, can the instrument be locked in the approximated position, and upon the subsequent operation of the handle assembly, will the operatirig bar 56 be free to move into engagement with pusher members 28 in a manner to urge them into driving engagement with the staples contained within staple cartridge 27.
Turning now to Figures 24 through 26, still another form of the second locking means of the invention is there illustrated. This form of second locking means is somewhat similar to that just described and like numbers are used to identify like components. This latest form of second locking means also functions to selectively disable the operating linkage 34a of the apparatus and here comprises a guide pin assembly which is similar to that shown in Figure 22C.
However, this assembly includes not only an elongated, rearwardly extending segment 127, which is connected to a slide member 129, but also includes a novel shuttle member 131. (See also Figures 24B and 24D) . In this latest form of the invention, it is this shuttle member that is selectively movable into blocking engagement with linkage 34a. More particularly, following staple firing and upon movement of Q 2~~ ~~ ~~ 1 guide pin 29 into the first retracted position shown in Figure 24, segment 127 engages and slidably moves shuttle member 131 to the location shown in Figure 24 where it is directly below linkage assembly 34a thereby preventing movement of the assembly into the overcenter locked position shown in Figure 26.
Referring particularly to Figures 24A and 24B, it is to be noted that segment 127 as well as pin 29 are connected to a slide member 129 which, as before, is slidably movable relative to frame 14 fr=om a forward guide pin advanced position shown in Figure 26 to the guide pin retracted position shown in Figure 24. When slide member 129 is moved into its rearward most position closely adjacent to handle portion 36, (Figure 24A) segment 127 extends into handle 36 to its maximum extent and urges shuttle 131 to its rearward most, first position shown in Figure 24A. However, because of the cooperative interaction between segment 127 and shuttle 131, when the slide member 129, along with guide pin 29, is moved to the forward most second position shown in Figures 26 and 26A, shuttle 131 is moved forwardly by segment 127 to the non-interfering second position shown in Figure 26 wherein the linkage can move into a recess 132 formed in the shuttle. In this regard it is to be noted that segment 127 includes an elongated dwell slot 133 (Figure 24B) within which an engagement pin 135 provided on shuttle 131 is slidably received. With this construction, when, and only when, guide pin 29 is in its forward most position will the end wall 133a of slot. 133 engage engagement pin 135 and urge the shuttle forwardly to the position shown in Figure 26. It should be noted that this feature allows the surgeon who has completed the firing-reopening-pin withdrawal cycle to use the stapler as a clamp. In this form, the instrument could function as an additional clamp, spring-biased in the open position, unless the surgeon squeezes the lever against the handle.
As best seen in Figure 25, as guide pin 29 is initially advanced a partial distance toward stationary jaw 21, shoulder 133a moves along a slot 131a formed in shuttle 131. However, in this position the shuttle itself remains in a stationary linkage blocking position so that an upstanding shoulder 131c formed on the shuttle prevents movement of linkage 34a into the overcenter position. Only after end wall 133a engages pin 135 will shuttle 131 start to move forwardly to the position shown in Figure 26 so that the linkage assembly can move into an overcenter position.
It is apparent that when this latest form of second locking means is used with. one of the first locking means previously described herein, such as for example, that shown in Figures 11 through 15, the existence of a spent cartridge in the instrument will once again prevent full advancement of the guide pin which, in turn, will prevent movement of shuttle 131 into the non-interfering positiori shown on Figure 26.
Therefore, until the spent staple cartridge is replaced with a fresh cartridge, the instrument will remain inoperable.
Similarly, after the instrument is fired and the guide pin retracted to remove the stapled tissue, shuttle 131 will block complete downward movement of the linkage assembly. To render the instrument operable, the spent staple cartridge must be replaced with a fresh cartridge to enable complete forward movement of the guide pin and advancement of the shuttle into a non-interfering forward position.
Having now described the invention in detail in accordance with the requirement of the patent statutes, those skilled in this art will have no difficulty in making changes and modifications in the individual parts or their relative assembly in order to meet specific requirements or conditions.
Such changes and modifications may be made without departing from the scope and spirit of the invention, as set forth in the following claims.
