Abstract
A surgical stapling device is disclosed for the treatment of internal hemorrhoids. The surgical stapling device includes a handle portion, an elongated body portion and a head portion including an anvil assembly and a shell assembly. The head portion includes an anvil assembly including a tiltable anvil which will tilt automatically after the device has been fired and unapproximated. The tiltable anvil provides a reduced anvil profile to reduce trauma during removal of the device after the anastomoses procedure has been performed. The anvil assembly of the stapling device may include an approximation mechanism having an anvil retainer including an elongated distal extension dimensioned to be telescopingly received within a longitudinal bore of an anvil center rod of the anvil assembly. The elongated distal extension is of a length to provide telescopic engagement with the anvil center rod without obstructing visualization of the surgical site. A kit including a surgical instrument having a removable anvil assembly and an anvil assembly insertion handle is also disclosed. The kit may also include a speculum, an anal dialator and/or an obturator.
Description
- This application claims priority from U.S. provisional application Ser. No. 60/480,074, filed Jun. 20, 2003, the contents of which are incorporated by reference in their entirety.
- 1. Technical Field
- The present disclosure relates generally to a surgical stapling device for applying surgical staples to body tissue. More particularly, the present disclosure relates to a surgical stapling device suitable for performing circular anastomosis and/or treatment to internal walls of hollow tissue organs.
- 2. Background of Related Art
- Anastomosis is the surgical joining of separate hollow organ sections. Typically, an anastomosis procedure follows surgery in which a diseased or defective section of hollow tissue is removed and the remaining end sections are to be joined. Depending on the desired anastomosis procedure, the end sections may be joined by either circular, end-to-end or side-to-side organ reconstruction methods.
- In a circular anastomosis procedure, the two ends of the organ sections are joined by means of a stapling instrument which drives a circular array of staples through the end section of each organ section and simultaneously cores any tissue interior of the driven circular array of staples to free the tubular passage. Examples of instruments for performing circular anastomsis of hollow organs are described in U.S. Pat. Nos. 6,053,390, 5,588,579, 5,119,983, 5,005,749, 4,646,745, 4,576,167, and 4,473,077, each of which is incorporated herein in its entirety by reference. Typically, these instruments include an elongated shaft having a handle portion at a proximal end to actuate the instrument and a staple holding component disposed at a distal end. An anvil assembly including an anvil rod with attached anvil head is mounted to the distal end of the instrument adjacent the staple holding component. Opposed end portions of tissue of the hollow organ(s) to be stapled are clamped between the anvil head and the staple holding component. The clamped tissue is stapled by driving one or more staples from the staple holding component so that the ends of the staples pass through the tissue and are deformed by the anvil head. An annular knife is concurrently advanced to core tissue with the hollow organ to free a tubular passage within the organ.
- Besides anastomosis of hollow organs, surgical stapling devices for performing circular anastomosis have been used to treat internal hemorrhoids in the rectum. Typically, during use of a circular stapling device for hemorrhoid treatment, the anvil head and the staple holding component of the surgical stapling device are inserted through the anus and into the rectum with the anvil head and the staple holding component in an open or unapproximated position. Thereafter, a pursestring suture is used to pull the internal hemorrhoidal tissue towards the anvil rod. Next, the anvil head and the staple holding component are approximated to clamp the hemorrhoid tissue between the anvil head and the staple holding component. The stapling device is fired to remove the hemorrhoidal tissue and staple the cut tissue.
- Using conventional circular anastomosis staplers to treat hemorrhoids has some difficulties. More specifically, because of the close proximity of the anvil head and staple holding component of the stapling device, visibility at the surgical site such as during placement of the pursestring suture is greatly impaired. Further, access to the surgical site is greatly restricted. As a result, it is difficult for a surgeon to effect proper placement of a pursestring suture into or adjacent hemorrhoidal tissue and also to verify that the pursestring suture has been properly placed and that the desired hemorrhoidal tissue is properly positioned for removal.
- Accordingly, a continuing need exists in the art for a circular stapling device suitable for treatment of hemorrhoids or the like which provides improved visibility and access to the surgical site.
- In accordance with the present disclosure, a circular surgical stapling device for performing circular anastomosis and/or treating internal hemorrhoids is disclosed. The surgical stapling device includes a handle portion or assembly, a body portion and a head portion including an anvil assembly and a shell assembly. The handle portion can include a rotatable approximation knob for approximating the anvil and shell assemblies and a firing trigger for actuating a firing mechanism for ejecting staples positioned within the shell assembly. In one embodiment, the firing trigger forms one link of a two bar linkage provided to actuate the firing mechanism. The two bar linkage provides the device with an improved mechanical advantage to reduce the firing forces required to fire the device.
- In one embodiment, the head portion includes an anvil assembly including a tiltable anvil which will tilt automatically when the device has been fired and unapproximated. The tiltable anvil provides a reduced anvil profile to reduce trauma during removal of the device after the anastomosis procedure has been performed.
- The surgical stapling device may also include a firing lockout mechanism which prevents actuation of the firing trigger until the device has been approximated. In one embodiment, the firing lockout mechanism includes a trigger lock and a lockout member which is movably positioned in the handle assembly. The lockout member prevents movement of the trigger lock from a locked to an unlocked position until the device has been approximated.
- In one embodiment, the surgical stapling device includes tactile indication mechanism. The tactile indication mechanism indicates to a surgeon that the anvil head has been unapproximated a distance sufficient to permit the anvil head to tilt, thus, indicating that the device can be removed from the patient.
- In another embodiment, the stapling device includes a bulbous indicator which extends above a top surface of the handle assembly of the device. The indicator includes indicia to identify to a surgeon that the device has been approximated and is in a fire-ready position. The indicator may include a cover which is formed of a magnification material to prominently display the indicia. The presently disclosed indicator provides improved visualization of the indicator to a surgeon from both the top and sides of the instrument.
- In another embodiment, the anvil assembly of the stapling device includes a retainer clip positioned on the anvil head. The retainer clip includes at least one resilient arm which is positioned to engage a cutting ring in its unbiased position to prevent the cutting ring from sticking to a knife blade during unapproximation of the stapling device. The retainer clip may include a pair of resilient arms which are positioned in a transverse slot in an anvil post of the anvil assembly. The cutting ring is positioned about the anvil post to urge the resilient arms into the transverse slot. The cutting ring is movable about the anvil post when the device is fired to allow the resilient arms of the retainer clip to flex outwardly to a position obstructing proximal movement of the cutting ring.
- In yet another embodiment, the surgical stapling device includes an approximation mechanism including an anvil retainer having an elongated distal extension which is telescopingly received within a longitudinal bore formed in the anvil center rod of the anvil assembly. The elongated distal extension may have a reduced diameter as compared to the proximal portion of the anvil retainer. The elongated distal extension should be of a length to facilitate telescopic engagement of the anvil retainer and anvil center rod without obstructing visualization of a surgical site. In one embodiment, the anvil retainer includes an engagement surface or shoulder for releasably engaging the anvil center rod. The shoulder is positioned proximally of the elongated distal extension. The approximation mechanism may also include a retainer extension member positioned between an approximation screw and the anvil retainer.
- In another embodiment, the surgical stapling device is included in a surgical kit suitable for treating internal hemorrhoids. The kit includes a surgical stapling device and a removable anvil assembly. In one embodiment, the surgical stapling device includes an anvil retainer having an elongated distal extension. The kit may also include an insertion handle which is adapted to releasably engage the anvil assembly to position the anvil assembly at a surgical site. The kit may also include a speculum, an anal dialator and/or an obturator.

FIGS. 36-44 illustratesurgical stapling device 10 withanvil assembly 30 attached toanvil retainer 38 and theanvil assembly 30 in the unapproximated or open position. Referring toFIGS. 37 and 38 , during attachment ofanvil assembly 30 toanvil retainer 38,anvil retainer 38 is positioned withinbore 170 ofcenter rod 154 ofanvil assembly 30.Flexible arms 155 deflect outwardly to accommodatecenter rod 154.Center rod 154 is advanced ontoanvil retainer 38 in the direction indicated by arrow “K” inFIG. 37 untilinternal shoulder 155 b offlexible arms 155 passes overannular protrusion 177 formed onanvil retainer 38. At this point,resilient legs 155 releasably engage the anvil retainer. The position of the remaining components of stapling device are unaffected by attachment ofanvil assembly 30 toanvil retainer 38 and remain as described above and shown inFIGS. 31-35 . -
FIGS. 45-50 illustratesurgical stapling device 10 during movement ofanvil assembly 30 andcartridge assembly 31 to the approximated or closed position. As discussed above,anvil assembly 30 is moved to the approximated or closed position by rotatingrotation knob 22 in the direction indicated by arrow “L” inFIG. 45 . Rotation ofknob 22 causescylindrical sleeve 33 to rotate to movepin 52 alonghelical channel 50 ofscrew 32. Movement of pin 52 (FIG. 48 ) alonghelical channel 50 causes screw 32 to translate withinsleeve 33. The distal end ofscrew 32 is connected to screwextensions anvil retainer 38. As such, retraction ofscrew 32 withinsleeve 33 is translated into proximal movement ofanvil retainer 38 andanvil assembly 30. It is noted that whenanvil assembly 30 is approximated,flexible legs 155 ofcenter rod 154 are drawn intobushing 209 to locklegs 155 ontoanvil retainer 38. (SeeFIG. 46 ). - As discussed above, screw stop 306 (
FIG. 47 ) is axially fixed to screw 32 byset screw 312. Thus, asscrew 32 is retracted withinsleeve 33, screw stop 306 is moved from a distal position withinstationary handle 18 to a proximal position. As screw stop 306 moves from the distal position to the proximal position,first engagement member 522 formed onscrew stop 306 abutsproximal end 506 a ofslot 506 ofslide plate 500 and moves slideplate 500 proximally against the bias ofspring 512. Asslide plate 500 moves proximally,lip 508 ofslide member 500 engagesprojections 518 & 520 ofindicator 24 to pivotindicator 24 in a counter-clockwise direction as viewed inFIG. 48 . -
Screw stop 306 also includes a second engagement member 548 (FIG. 47 ). Asscrew stop 306 is moved from the distal position to the proximal position during approximation ofanvil assembly 30,second engagement member 548 engagesdistal legs 540 a oflockout member 530 to movelockout member 530 proximally to a position in whichlip portion 542 is spaced proximally of extension 26 b oftrigger lock 26. In this position, triggerlock 26 can be pivoted to an unlocked position to permit firing of staplingdevice 10. - Movement of screw stop 306 to its proximal-most position within
stationary handle 18 positions abutment surface 307 (FIG. 48 ) ofscrew stop 306 in position to engagepivot member 79 of firinglink 72.Abutment surface 307 comprises a substantially concave surface which is positioned to partially capture and act as a backstop forpivot 79 during firing of the stapling device. -
FIGS. 51-56 illustratesurgical stapling device 10 during the firing stroke of firingtrigger 20. Astrigger 20 is compressed towards stationary handle 18 (as shown by the arrow in FIG. 51),pivot member 79 engagesabutment surface 307 onscrew stop 306 and firingtrigger 20 is pushed distally. As discussed above, the distal end of firingtrigger 22 is connected throughcoupling member 86 to the proximal end ofpusher link 74. Accordingly, as firingtrigger 20 is moved distally,pusher link 74 is moved distally to effect advancement of pusher back 186 withinshell assembly 31.Fingers 190 of pusher back 186 engage and ejectstaples 230 from staple guide 192 (FIG. 52 ). -
Cylindrical knife 188 is moved concurrently with pusher back 186 such thatknife 188 moves into engagement with cuttingring 128 andbackup plate 126. As discussed above, cuttingring 128 may be formed from polyethylene andbackup plate 126 may be formed from a metal. Whenknife 188 engages cuttingring 128, it cuts into cuttingring 128 and pushesbackup plate 126 deeper intoanvil head 124 to movetabs 150 from engagement withtop surface 154 a of center rod 154 (FIG. 56 ).Anvil head 124 is now free to pivot aboutmember 164 and is urged to do so byplunger 156. It is noted that because the anvil assembly is in juxtaposed alignment withshell assembly 31, theanvil head 14 will not pivot fully until the anvil and shell assemblies have been unapproximated a distance sufficient to allow the anvil head to fully pivot. Whenbackup plate 126 moves intoanvil head 124,flexible arms 127 a and 127 b ofretainer clip 127 spring outwardly to a position in front ofbackup plate 126 blocking movement ofbackup plate 126 out of anvil head 124 (FIG. 55 ). As discussed above,arms 127 a and 127 b preventbackup plate 126 from sticking toknife 188 whenanvil assembly 30 is returned to the unapproximated position. - Referring to
FIGS. 57-60 , during unapproximation of staplingdevice 10 afterdevice 10 has been fired,wing 584 ofscrew stop 306 engages tactile indicator 580 (FIG. 58 ) at the point of unapproximation at whichanvil assembly 124 is able to pivot to its tilted reduced profile position. Contact betweenwing 584 andtactile indicator 580 provides a tactile and/or audible indication thatanvil head 124 has tilted. If additional force is provided toapproximation knob 22,wing 584 ofscrew stop 306 will force tactile indicator to the retracted position to allow staplingdevice 10 to move to the fully open position. In this position,flexible arms 155 are positioned distally ofbushing 209 andanvil assembly 30 can be disengaged from anvil retainer 28. -

Althoughanvil head assembly 684 may be pivotally secured toanvil center rod 686, as discussed above, in one embodiment,anvil head assembly 684 is fixedly secured toanvil center rod 686. - As illustrated in
FIGS. 86 and 87 and 90,anvil center rod 686 defines acentral bore 700 which is partially defined by a plurality offlexile arms 702. Central bore 700 extends substantially along the longitudinal length ofcenter rod 686. The distal end of eachflexible arm 702 includes aradial projection 702 a. Central bore 700 is dimensioned to slidably receive anvil retainer 610 (FIG. 62 ) includingdistal extension 630 such thatradial projections 702 a snap over and engage annular shoulder 632 (FIGS. 70 and 71 ) ofanvil retainer 610 to secureanvil assembly 640 toanvil retainer 610.Radial projection 702 a (FIG. 90 ) defines a perpendicular surface which abutsshoulder 632 to securely fastenanvil assembly 640 toanvil retainer 610 and substantially prevent inadvertent disengagement ofanvil assembly 640 fromanvil retainer 610. Whenanvil assembly 640 is secured toanvil retainer 610,distal extension 630 ofanvil retainer 610 extends throughcentral bore 700 along a substantial portion of the length ofanvil center rod 686. In one embodiment,distal extension 630 extends throughcentral bore 700 substantially the entire length ofanvil center rod 686. - In use, when approximation knob 602 (
FIG. 63 ) is manually rotated to movescrew 606 proximally,anvil retainer 610 andanvil assembly 640 are withdrawn intoshell assembly 642 to moveanvil head assembly 684 into approximation with shell assembly 642 (FIG. 65 ). Whenflexible arms 702 are drawn intocylindrical bore 668 ofinner guide portion 644 b,arms 702 are prevented from flexing outwardly to lockanvil assembly 640 toanvil retainer 610. - As discussed above, stapling
device 600 is particularly suitable for use in surgical procedures for removing internal hemorrhoids from a patient. During such a procedure, anvil assembly 640 (FIG. 64 ) is inserted into the anus and rectum of the patient independently of staplingdevice 600. Referring toFIGS. 93-95 , aninsertion handle 720 may be used to facilitate insertion ofanvil assembly 640 into the anus and rectum. In one embodiment, handle 720 includes agripping knob 722, arigid shaft 725 extending distally fromknob 722 and anattachment portion 724.Attachment portion 724 includes adetent 726 and aprotrusion 728.Attachment portion 725 ofshaft 724 is dimensioned to be slidably received within anvil center rodcentral bore 700.Detent 726 is positioned to be received within one of a plurality of suture holes 730 (FIG. 87 ) formed in the distal end ofanvil center rod 686 to releaseably lock handle 720 toanvil center rod 686.Protrusion 728 is positioned to be slidably received between and engaged byflexible arms 702 to properly alignhandle 720 withanvil center rod 686. Astop member 728 a may also be provided on the attachment portion to limit the insertion depth ofshaft 724 intocentral bore 700. To remove handle 720 fromanvil center rod 686, a force sufficient to flexflexible arms 702 outwardly must be applied to handle 720 to releasedetent 726 fromsuture hole 730. In one embodiment, afteranvil assembly 640 has been properly positioned in the anus and rectum, a purse string suture is placed into each of the internal hemorrhoids. Thereafter, the purse string is cinched about theanvil center rod 686 to draw the internal hemorrhoids inwardly about theanvil center rod 686. - Referring to
FIGS. 96-99 , in an alternate embodiment, the purse string suture may be placed into the internal hemorrhoids prior to insertion of the anvil assembly into the anus and rectum. Using either embodiment, an anoscope orspeculum 750, may be provided to place the purse string into the internal hemorrhoids.Speculum 750 may include asemi-cylindrical body 752 having a tapered orblunt tip 754.Body 752 defines a channel orrecess 756. The proximal end ofbody 752 has asemi-annular flange 758 including a plurality ofopenings 760 and a pair of protrudingfinger tabs 762.Fingers tabs 762 andopenings 760 allow for easier gripping and manipulation of the speculum during use. It is also envisioned thatspeculum 750 may be formed from a clear plastic material to enhance visualization. Further, thespeculum 750 may include gradation markings (not shown) along the surface of thespeculum 750 to assist the surgeon with knowledge of depth of placement of the hemorrhoids. - In use,
blunt tip 754 ofspeculum 750 is inserted into the anus to a position in which first internal hemorrhoids hang intochannel 756. A purse string suture is placed into a first portion of internal hemorrhoids.Speculum 750 is then rotated usingfinger tabs 762 andopenings 760 until a second portion of internal hemorrhoids hang intochannel 756. A purse string suture is placed into the second internal hemorrhoids. This process is repeated until a purse string suture has been placed into each of the internal hemorrhoids about the annulus of the anus. - When a purse string suture has been placed into each of the internal hemorrhoids,
speculum 750 is removed from the anus and theanvil assembly 640 is inserted into the anus and rectum. Thereafter, the purse string sutures are cinched to draw the internal hemorrhoids in about theanvil center rod 686. Attachment structure such as openings, grooves, hooks, ridges or ribs, may be provided onanvil center rod 686 to secure the purse string suture and, thus, the internal hemorrhoids to theanvil center rod 686. It is also envisioned that the attachment structure may be in the form of an axially adjustable member, e.g., slidable hook, which may be adjusted to change the position of the purse string suture onanvil center rod 686 and withinshell assembly 642. Likewise, gradations can be placed on thecenter rod 686 to indicate depth of insertion of thecenter rod 686 or length of the suture or of sutured hemorrhoids. - After the internal hemorrhoids have been cinched about
anvil center rod 686,center rod 686 is attached toanvil retainer 610 in the manner discussed above.Distal extension 630 andanvil center rod 686 should be of a length to allow telescoping ofextension 630 withinanvil center rod 686 before visibility of the surgical site is obstructed byshell assembly 642 ofdevice 600. In one embodiment, the combined length ofanvil center rod 686 andretainer extension 630 is at least 4.5 inches (114.3) or of a length to achieve the above objective. By providing an extension onanvil retainer 610 and/or providing an elongatedanvil center rod 686, visibility at the surgical site is greatly improved. Improved visibility not only simplifies attachment ofanvil assembly 640 toanvil center rod 686 but improves visibility during approximation of anvil to ensure that the hemorrhoidal tissue is properly positioned about the anvil shaft. - After the anvil assembly has been attached to the
anvil center rod 686,knob 602 can be manually rotated to approximate the anvil and shell assemblies and draw the internal hemorrhoids into an inner chamber 780 (FIG. 62 ) defined withinpusher 646 and withinannular knife 682 ofshell assembly 642. Firing trigger 790 (FIG. 62 ) can now be actuated in the manner discussed above with respect to staplingdevice 10 to staple, sever and allow removal of the internal hemorrhoids. Thereafter, staplingdevice 600 is removed from the anus with the excised internal hemorrhoids contained withininner chamber 780 ofshell assembly 642. - It is envisioned that instrument accessories may be used to assist in performing particular steps of the above described procedures. For example, an anal dialator may be inserted into the anus prior to performing the above-described method steps to provide easier access to the surgical site. An obturator may be used to assist in placement of the dialator. Also, an expandable introducer may be provided to reduce the trauma that results from insertion of the stapling device into the anus. Further, any combination of the components discussed above including the stapling device, anvil assembly, insertion handle, speculum anal dialator, and/or an obturator may be included in a kit to perform a hemorrhoidal treatment procedure.
- It is noted that by providing a surgical stapler having a removable anvil assembly, visibility at the surgical site is greatly improved. This is especially important during placement of the purse string suture and cinching of the purse string suture about the anvil center rod.
- It will be understood that various modifications may be made to the embodiments disclosed herein. Therefore, the above description should not be construed as limiting, but merely as exemplifications of disclosed embodiments. Those skilled in the art will envision other modifications within the scope and spirit of the claims appended hereto.
