Description
Technical field
The present invention relates to the grip thickness governor motion in various surgical linear Endo-GIAs, particularly relate to the grip thickness governor motion of the adjustable surgical linear Endo-GIA of grip thickness.
Background technology
Various surgical linear Endo-GIAs are used for replacing surgical operation to adopt the free-hand identical operation of needlework, be widely used in the operations such as the end end of human body alimentary canal organ, respiratory tract organ and apparatus urogenitalis official rank Organ and tissue, distolateral and side to side anastomosis, form the operation of organ passage and the operation of close incisions, be specially adapted to appear the anastomosis operation with the Organ and tissue of operating difficulties, can reduce operating time, improve the operation quality.
As introducing in United States Patent (USP) publicity 20050222616,20080116244 and 20090308909: known various surgical linear Endo-GIAs are comprised of nail bin groupware, nail-anvil assembly and clamp mechanism.Nail bin is arranged in nail bin groupware, the nail bin frame of nail bin is installed and is arranged on the interior firing lock of nail bin frame.Firing lock is tiltedly carved with cutter by push button, slide block, push rod, ejector pin and is formed.It is linear that nail bin is, can be both rectilinear, also can be curved.Ejector pin piece and anastomosis staple are installed in nail bin.A plurality of anastomosis staples are staggered in nail bin more than two rows (comprising two rows).Nail anvil and nail anvil frame are arranged in nail-anvil assembly.Nail anvil can be made one with the nail anvil frame.It is linear that nail anvil is, can be both rectilinear, also can be curved.Be arranged with the anastomosis staple grooving corresponding with the anastomosis staple position in nail bin on the surface of nail anvil.A plurality of anastomosis staple groovings are being staggered on the surface of nail anvil more than two rows (comprising two rows).Clamp mechanism is comprised of nail bin frame, nail anvil frame and clamp hook, and clamp hook and nail bin frame/nail anvil frame are pivotally connected.When execution clamps when coincideing the operation of organizing, after rotating, the clamp hook pivot hooks the projection on nail anvil frame/nail bin frame, will wait to coincide clamp tissue between nail anvil and nail bin.Anastomosis staple in nail bin takes the shape of the letter U.When the ejector pin piece is released anastomosis staple in nail bin, the nail tip of the anastomosis staple of U-shaped is pressed on the grooving of nail anvil, make two nail lower limbs of the anastomosis staple of U-shaped bend to the anastomosis staple of B shape along grooving, reach the operation purpose of will tissue coincideing.In order to reach the operation purpose that tissue is coincide, for the coincide anastomosis staple of the different nail of organization need use lower limb height and the nail bin of differing heights waited of different grip thickness.Organize not only soft but also flexible owing to waiting to coincide, be difficult to determine the thickness of suitable identical tissue, need to change the nail bin of the anastomosis staple of selecting the different nail lower limb of being equipped with of various grip thickness height in operation, generally that clamp tissue thickness every 0.5mm is divided into a specification, increased the cost of operation technique number of times and apparatus, therefore the surgical linear Endo-GIA of this style is difficult to satisfy the requirements of operation of various thickness tissues of coincideing, thereby has reduced surgical effect, increased operating difficulty and the cost of performing the operation.Therefore the grip thickness governor motion of surgical linear Endo-GIA also need improve.
As the surgical linear Endo-GIA of introducing in United States Patent (USP) publicity 20110068145 and 20110155787: the anastomosis staple in nail bin takes the shape of the letter U, and two groovings that separate are arranged on the surface of nail anvil.When the ejector pin piece is released anastomosis staple in nail bin, the nail tip of anastomosis staple is pressed on respectively on the grooving of nail anvil, make two nail lower limbs of anastomosis staple bend to spiral anastomosis staple along two groovings that separate respectively, reach the operation purpose of will tissue coincideing.Because two of anastomosis staple nail lower limbs bend to spiral anastomosis staple, therefore, the identical anastomosis staples that do not need to use different nail lower limb height of organizing for the treatment of for different grip thickness, only need to adopt the same nail bin of the anastomosis staple that identical nail lower limb height is housed, regulate clamping gap between nail bin groupware and nail-anvil assembly by the grip thickness governor motion, namely applicable to the tissue that coincide of waiting of the different grip thickness of coincideing.But the grip thickness governor motion needs the arrowhead position of while regulating nail chopping block and pressing plate when regulating grip thickness.Wherein, when the arrowhead position of regulating nail chopping block, a step-like adjustable plate need to be inserted in nail anvil, hold the step-like nail anvil plate with grooving.The unsatisfactory place of the grip thickness governor motion of the surgical linear Endo-GIA of this style is: first, the nail anvil of surgical linear Endo-GIA is elongated bar, when holding the arrowhead position with the step-like nail anvil plate regulating nail chopping block of grooving in step-like adjustable plate inserts nail anvil, can be subject to larger resistance, be not easy to operation technique; Second, because the nail anvil plate is thinner, when step-like adjustable plate is held step-like nail anvil plate with grooving, the larger cavity of each stairstepping interval formation of adjustable plate and nail anvil plate, thereby when making two nail lower limbs along the grooving bending forming on the nail tip of anastomosis staple is pressed on the grooving of nail anvil, the active force that produces can make the flexural deformation of nail anvil plate, affects anastomosis staple and correctly is shaped, i.e. impact will be organized the surgical effect of coincideing; The 3rd, hold arrowhead position with the step-like nail anvil plate regulating nail chopping block of grooving in order to make step-like adjustable plate, respectively there are two guiding grooves two sides at nail anvil, the tissue around the pin that has arrowhead to move in guiding groove, the pin that this guiding groove and arrowhead move can abrade; The 4th, because the clamp mechanism of nail bin groupware and nail-anvil assembly is the long cantilever girder construction, adjustable plate and nail anvil plate occupy larger space in nail anvil, be conditioned in order to make up the nail anvil rigidity that plate and nail anvil plate weaken, therefore need to increase width and the height of nail anvil, like this, not only increased the weight of nail anvil but also increased the volume of nail anvil, thereby not only easily caused operation fatigue but also reduced the operation subject range of surgical stapling.Therefore the grip thickness governor motion of surgical linear Endo-GIA also need improve.
Obviously can be found out by above-mentioned, a large amount of not in specie surgical linear Endo-GIAs have been designed now, and the development work of the grip thickness governor motion of new surgical linear Endo-GIA is still continuing, so that the surgical linear Endo-GIA that used in a large number every year in the world is improved further, the surgical effect of the operation subject range that reach lighter, more reliable when using, does not reduce the surgical linear Endo-GIA.

Surgical linear Endo-GIA 7 is comprised of nail bin groupware 8, nail-anvil assembly 9 and grip thickness governor motion 10.To shown in Figure 6, surgical linear Endo-GIA 7 is in respectively open configuration, clamp position and clamped condition as Fig. 1.
As shown in Figure 7, have in nail bin groupware 8 nail bin 11, the nail bin frame 12 of nail bin 11 is installed and is arranged on firing lock 13 in nail bin frame 12.Ejector pin piece (not shown) and anastomosis staple (not shown) are installed in nail bin 11.A plurality of anastomosis staples respectively are staggered to two rows in the both sides of nail bin cutter groove 14.
To shown in Figure 13, nail anvil 15 and nail anvil frame 16 are arranged in nail-anvil assembly 9 as Figure 10.Be arranged with the anastomosis staple grooving 17 corresponding with the anastomosis staple position in nail bin 11 on the surface of nail anvil 15.A plurality of anastomosis staple groovings 17 respectively are staggered to two rows on the both side surface of nail anvil cutter groove 18.
To shown in Figure 21, grip thickness governor motion 10 is comprised of nail bin frame 12, nail anvil frame 16, clamp hook 19, grip thickness adjusting slider 20 and slide bumping 21 as Fig. 7.As shown in Figure 7, pivot 22 and briquetting 23 are arranged on nail bin frame 12.As Fig. 8 and shown in Figure 9, pivot hole 24 and hook 25 are arranged on clamp hook 19.The pivot 22 of nail bin frame 12 inserts the pivot hole 24 of clamp hook 19, forms the pivotally connected of clamp hook 19 and nail bin frame 12.As Figure 11 and shown in Figure 12, vertical chute 26 and arrowhead chute 27 are arranged on nail anvil frame 16.As shown in figure 14, the near-end of grip thickness adjusting slider 20 has stairstepping projection 28, far-end that waveform skewed slot 29 is arranged.The cascaded surface of stairstepping projection 28 is cambered surface.Projection 30 on slide bumping 21 is constrained in the waveform skewed slot 29 of grip thickness adjusting slider 20.
As extremely shown in Figure 21 in Fig. 7, when grip thickness adjusting slider 20 under the constraint of vertical chute 26 of nail anvil frame 16 during along the vertically moving of nail anvil frame 16, the stairstepping projection 28 of grip thickness adjusting slider 20 and waveform skewed slot 29 be also along with along the vertically moving of nail anvil frame 16, and makes the waveform skewed slot skewed slot 29 of grip thickness adjusting slider 20 drive slide bumpings 21 arrowhead along nail anvil frame 16 under the constraint of the arrowhead chute 27 of nail anvil frame 16 and move.Thereby both regulated the distance between the pivot 22 on the nail bin frame 12 of projection 30 on the slide bumping 21 that is arranged on nail-anvil assembly 9 and nail bin groupware 8, regulated again the distance between the briquetting 23 on the nail bin frame 12 of the stairstepping projection 28 of the grip thickness adjusting slider 20 that is arranged on nail-anvil assembly 9 and nail bin groupware 8.
As extremely shown in Figure 6 in Fig. 1, after nail bin groupware 8 and nail-anvil assembly 9 close up mutually, clamp hook 19 is rotated around nail bin frame 12 pivots, make hook 25 on clamp hook 19 hook projection 30 on slide bumping 21, drive briquetting 23 on nail bin frame 12 and be pressed on projection 30 on slide bumping 21, make the clamped hook of nail bin groupware 8 and nail-anvil assembly 9 clamp.
Because the pivot hole 24 on clamp hook 19 and the distance between hook 25 are constant, so grip thickness adjusting slider 20 has been regulated the clamped thickness of organizing between nail bin groupware 8 and nail-anvil assembly 9.Fig. 3, Fig. 4, Fig. 6 and Figure 10 represent, when surgical linear Endo-GIA 1 is in thicker clamped condition at nail bin groupware 8 and nail-anvil assembly 9, and the mutual alignment of each part of grip thickness governor motion 10.Figure 16 to Figure 18 represents, when surgical linear Endo-GIA 1 mediates clamped condition at nail bin groupware 8 and nail-anvil assembly 9, and the mutual alignment of each part of grip thickness governor motion 10.Figure 19 to Figure 21 represents, when surgical linear Endo-GIA 1 is in thinner clamped condition at nail bin groupware 8 and nail-anvil assembly 9, and the mutual alignment of each part of grip thickness governor motion 10.
As shown in figure 15, slide bumping 21 is comprised of balladeur train 31 and the round pin 32 that is inserted on balladeur train 31.Round pin 32 inserts simultaneously in the arrowhead chute 27 of nail anvil frame 16 and in the waveform skewed slot 29 of grip thickness adjusting slider 20, balladeur train 31 is constrained on the interior arrowhead along nail anvil frame 16 of nail-anvil assembly 9 and moves.Spring 33 is installed on balladeur train 31.Spring 33 keeps towards the arrowhead mobile trend with the face of the nail anvil 15 of anastomosis staple grooving 17 round pin 32 on balladeur train 31.
As shown in figure 22, the near-end of the grip thickness adjusting slider 34 of the second embodiment in the grip thickness governor motion 10 of surgical linear Endo-GIA 7 of the present invention has stairstepping projection 35, far-end that stepped skew 36 is arranged.The cascaded surface of stairstepping projection 35 is the plane.In the grip thickness governor motion 10 of this grip thickness adjusting slider 34 in surgical linear Endo-GIA 7, the effect in the thickness of regulating clamped tissue between nail bin groupware 8 and nail-anvil assembly 9 and grip thickness adjusting slider 20 identical.
According to above-mentioned detailed introduction as can be known, compare with existing various surgical linear Endo-GIAs, the grip thickness governor motion of surgical linear Endo-GIA of the present invention has following technique effect:
Existing most of surgical linear Endo-GIA is in order to reach the operation purpose that tissue is coincide, for the coincide anastomosis staple of the different nail of organization need use lower limb height and the nail bin of differing heights waited of different grip thickness.Organize not only soft but also flexible owing to waiting to coincide, be difficult to determine the thickness of suitable identical tissue, need to change the nail bin of the anastomosis staple of selecting the different nail lower limb of being equipped with of various grip thickness height in operation, generally that clamp tissue thickness every 0.5mm is divided into a specification, increased the cost of operation technique number of times and apparatus, therefore the surgical linear Endo-GIA of this style is difficult to satisfy various thickness and waits the requirements of operation of tissue of coincideing, thereby has reduced surgical effect, increased operating difficulty and operation cost.
Recently surgical linear Endo-GIA, grip thickness governor motion need the arrowhead position of while regulating nail chopping block and pressing plate when regulating grip thickness.Wherein, when the arrowhead position of regulating nail chopping block, a step-like adjustable plate need to be inserted in nail anvil, hold the step-like nail anvil plate with grooving.The unsatisfactory place of the grip thickness governor motion of the surgical linear Endo-GIA of this style is: first, the nail anvil of surgical linear Endo-GIA is elongated bar, when holding the arrowhead position with the step-like nail anvil plate regulating nail chopping block of grooving in step-like adjustable plate inserts nail anvil, can be subject to larger resistance, be not easy to operation technique; Second, when step-like adjustable plate is held step-like nail anvil plate with grooving, the larger cavity of each stairstepping interval formation of adjustable plate and nail anvil plate, thereby when making two nail lower limbs along the grooving bending forming on the nail tip of anastomosis staple is pressed on the grooving of nail anvil, the active force that produces can make the flexural deformation of nail anvil plate, affect anastomosis staple and correctly be shaped, i.e. impact will be organized the surgical effect of coincideing; The 3rd, hold arrowhead position with the step-like nail anvil plate regulating nail chopping block of grooving in order to make step-like adjustable plate, respectively there are two guiding grooves two sides at nail anvil, the tissue around the pin that has arrowhead to move in guiding groove, the pin that this guiding groove and arrowhead move can abrade; The 4th, because the clamp mechanism of nail bin groupware and nail-anvil assembly is cantilever beam structures, adjustable plate and nail anvil plate occupy larger space in nail anvil, be conditioned in order to make up the nail anvil rigidity that plate and nail anvil plate weaken, width and the height of nail anvil have been increased, not only increase the weight of nail anvil but also increased the volume of nail anvil, thereby not only easily caused operation fatigue but also reduced the operation subject range of surgical linear Endo-GIA.
the grip thickness governor motion of surgical linear Endo-GIA of the present invention, realize when the grip thickness adjusting slider during along the vertically moving of nail anvil frame, the projection of grip thickness adjusting slider and skewed slot are also along with vertically moving along the nail anvil frame, make skewed slot drive slide bumping arrowhead along the nail anvil frame under the constraint of the arrowhead chute of nail anvil frame of grip thickness adjusting slider move, both regulated the distance between the pivot on the nail bin frame of projection on the slide bumping that is arranged on nail-anvil assembly and nail bin groupware, regulated again the distance between the briquetting on the nail bin frame of the projection of the grip thickness adjusting slider that is arranged on nail-anvil assembly and nail bin groupware.Because the pivot hole on clamp hook and the distance between hook are constant, so the grip thickness governor motion has reached the result of use of organizing clamped thickness of regulating between nail bin groupware and nail-anvil assembly.If the step number of the skewed slot on the grip thickness adjusting slider is more or the wave number is more, the step number of the projection on the grip thickness adjusting slider is more, organizes the adjustable separation number of clamped thickness more between nail bin groupware and nail-anvil assembly.Because the grip thickness governor motion moves on the nail anvil frame beyond nail anvil, any position of neither occupying in nail anvil does not change again the structure of nail anvil, therefore, regulate between nail bin groupware and nail-anvil assembly organize clamped thickness the time, the resistance that is subject to is less, do not increase width and the height of nail anvil, do not affect rigidity and the intensity of nail anvil yet, more do not have the accessory structure of scratch tissue on every side.Compare with existing surgical linear Endo-GIA, lighter, more reliable during surgical linear Endo-GIA use of the present invention, as not reduce surgical linear Endo-GIA operation subject range has improved the surgical effect that tissue coincide.
the grip thickness governor motion of surgical linear Endo-GIA of the present invention, insert simultaneously in the arrowhead chute of nail anvil frame due to the round pin of slide bumping and in the waveform skewed slot of grip thickness adjusting slider, spring keeps towards the arrowhead mobile trend with the face of the nail anvil of anastomosis staple grooving the round pin on balladeur train, thereby make at the grip thickness adjusting slider during along the vertically moving of nail anvil frame, under the effect of the waveform skewed slot of grip thickness adjusting slider and spring and under the constraint of the arrowhead chute of nail anvil frame, projection on slide bumping is beated in the waveform skewed slot of grip thickness adjusting slider, constantly change the grip thickness adjusting slider along the resistance that vertically moves of nail anvil frame and sound, compare with existing surgical linear Endo-GIA, surgical linear Endo-GIA of the present invention reaches the grip thickness governor motion by feeling and the better result of use of the variation that the double-reminding operator grip thickness of sounding is regulated, on the other hand, the grip thickness adjusting slider along the nail anvil frame vertically move end after, under the effect of the waveform skewed slot of grip thickness adjusting slider and spring and under the constraint of the arrowhead chute of nail anvil frame, projection on slide bumping is fixed on the position of regulating, compare with existing surgical linear Endo-GIA, surgical linear Endo-GIA of the present invention reaches the grip thickness governor motion and makes tissue between nail bin groupware and nail-anvil assembly be fixed on the locational better result of use of the grip thickness of regulating.
The surgeon for the waiting to coincide and organize the nail bins of the anastomosis staple that does not need to use different nail lower limb height of different grip thickness, only needs to adopt the same nail bin of the anastomosis staple that identical nail lower limb height is housed when using surgical linear Endo-GIA of the present invention.first will wait to coincide clamp tissue between nail bin and nail anvil, if the sensation grip thickness is improper, due to regulate between nail bin groupware and nail-anvil assembly organize clamped thickness the time grip thickness governor motion resistance that is subject to less, will not unclamp by the surgical linear Endo-GIA, only need nail bin groupware and the nail-anvil assembly of surgical linear Endo-GIA are in clamp position shown in Figure 2, namely can be directly by the clamping gap between grip thickness governor motion adjusting nail bin groupware and nail-anvil assembly, when the grip thickness governor motion is regulated clamping gap between nail bin groupware and nail-anvil assembly, the grip thickness governor motion is by feeling and the double-reminding operator that sound notice the variation that grip thickness is regulated, and then try to clamp and wait the tissue that coincide, until satisfied, at this moment, can pass through firing lock, anastomosis staple is released in nail bin, make the nail tip of anastomosis staple penetrate the clamped identical grooving that directes reach on nail anvil of organizing for the treatment of, reaching will the identical operation purpose of tissue.When using in surgical operation, compare with existing surgical linear Endo-GIA, lighter, more reliable during surgical linear Endo-GIA use of the present invention, as not reduce surgical linear Endo-GIA operation subject range, operating time is shorter, has improved the surgical effect that tissue coincide.
So can find out that the above-mentioned target of stating comprises by front those shown targets of explanation being effectively achieved.Described here is only the typical best form of implementation of the present patent application, can do some to said structure and change also without prejudice to the spirit and scope of the present invention.The present invention is not limited to the detail of stating here, is apparent any improvement or remodeling and should keep affiliated field secondary technology personnel as stating in the restriction of claim.
