Description
Technical field
The present invention relates to the grip thickness governor motion in various surgical linear Endo-GIA, particularly relate to the grip thickness governor motion of the adjustable surgical linear Endo-GIA of grip thickness.
Background technology
Various surgical linear Endo-GIA adopts the free-hand anastomosis procedure of needlework for replacing in surgical operation, 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, side 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 operating time be reduced, improve surgical quality.
As in United States Patent (USP) publicity 20050222616,20080116244 and 20090308909 introduce: known various surgical linear Endo-GIA, is made up of nail bin groupware, nail-anvil assembly and clamp system.Nail bin, the nail bin frame installing nail bin and the firing lock be arranged in nail bin frame is had in nail bin groupware.Firing lock is tiltedly carved by push button, slide block, push rod, ejector pin and is formed with cutter.Nail bin is linear, both can be rectilinear, also can be curved.Ejector pin block and anastomosis staple are installed in nail bin.Multiple anastomosis staple is staggered to more than two rows (comprising two rows) in nail bin.Nail anvil and nail anvil frame is had in nail-anvil assembly.Nail anvil can make one with nail anvil frame.Nail anvil is linear, both can be rectilinear, also can be curved.The surface of nail anvil is arranged with the anastomosis staple grooving corresponding with the anastomosis staple position in nail bin.Multiple anastomosis staple grooving is staggered to more than two rows (comprising two rows) on the surface of nail anvil.Clamp system is made up of nail bin frame, nail anvil frame and clamp hook, clamp hook and nail bin frame/nail anvil frame pivotally connected.When performing the operation of clamping tissue to be anastomosed, hook the projection on nail anvil frame/nail bin frame after clamp hook pivot, by clamp tissue to be anastomosed between nail anvil and nail bin.Anastomosis staple in nail bin takes the shape of the letter U.When anastomosis staple is released by ejector pin block in nail bin, the nail tip of the anastomosis staple of U-shaped is pressed on the grooving of nail anvil, makes two of the anastomosis staple of U-shaped nail lower limbs bend to the anastomosis staple of B shape along grooving, reach the operation object of engaging tissue.In order to reach the operation object of engaging tissue, the organization need to be anastomosed for different grip thickness uses the different anastomosis staple of nail lower limb height and the nail bin of differing heights.Due to be anastomosed organize not only soft but also flexible, be difficult to the thickness determining suitable anastomosed tissue, in operation, need to change the nail bin that the anastomosis staple of different nail lower limb height is housed selecting various grip thickness, generally be divided into a specification every the clamp tissue thickness of 0.5mm, add the cost of operation technique number of times and apparatus, therefore the surgical linear Endo-GIA of this style is difficult to meet the requirements of operation of various thickness tissue of coincideing, thus reduces surgical effect, adds operating difficulty and cost of performing the operation.Therefore the grip thickness governor motion of surgical linear Endo-GIA also needs to improve.
As in United States Patent (USP) publicity 20110068145 and 20110155787 the surgical linear Endo-GIA introduced: the anastomosis staple in nail bin takes the shape of the letter U, and the surface of nail anvil has two groovings separated.When anastomosis staple is released by ejector pin block in nail bin, the nail tip of anastomosis staple be pressed on respectively on the grooving of nail anvil, the grooving that two of anastomosis staple nail lower limbs are separated along two respectively bends to spiral anastomosis staple, reaches the operation object of engaging tissue.Because two nail lower limbs of anastomosis staple bend to spiral anastomosis staple, therefore, the anastomosis staple not needing to use different nail lower limb height is organized for the to be anastomosed of different grip thickness, only need adopt the same nail bin of the anastomosis staple that identical nail lower limb height is housed, regulate the clamping gap between nail bin groupware and nail-anvil assembly by grip thickness governor motion, be namely applicable to the tissue to be anastomosed of identical different grip thickness.But grip thickness governor motion, when regulating grip thickness, needs the arrowhead position of regulating nail chopping block and pressing plate simultaneously.Wherein, when the arrowhead position of regulating nail chopping block, need a step-like adjustable plate to insert 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 elongate strip, when step-like adjustable plate inserts in nail anvil the arrowhead position of holding with the step-like nail anvil plate regulating nail chopping block of grooving, larger resistance can be subject to, be not easy to operation technique; Second, because nail anvil plate is thinner, when step-like adjustable plate holds the step-like nail anvil plate with grooving, each stairstepping interval of adjustable plate and nail anvil plate forms larger cavity, thus when the grooving that the nail tip of anastomosis staple is pressed on nail anvil makes two to follow closely lower limbs along grooving bending forming, the active force produced can make nail anvil plate benging be out of shape, and affects anastomosis staple and is correctly shaped, namely affect the surgical effect of engaging tissue; 3rd, in order to the arrowhead position making step-like adjustable plate hold the step-like nail anvil plate regulating nail chopping block with grooving, respectively have two guiding grooves in two sides of nail anvil, have the pin of arrowhead movement in guiding groove, the pin of this guiding groove and arrowhead movement can abrade the tissue of surrounding; 4th, because the clamp system of nail bin groupware and nail-anvil assembly is long cantilever girder construction, adjustable plate and nail anvil plate occupy larger space in nail anvil, in order to make up the nail anvil rigidity being conditioned plate and nail anvil plate and weakening, therefore the width and the height that increase nail anvil is needed, like this, the weight both having added nail anvil turn increases the volume of nail anvil, thus has both easily caused operation fatigue to additionally reduce the operation subject range of surgical stapling.Therefore the grip thickness governor motion of surgical linear Endo-GIA also needs to improve.
As can be seen from obviously above-mentioned, devise now a large amount of not surgical linear Endo-GIA in specie, and the development work of the grip thickness governor motion of new surgical linear Endo-GIA is still in continuation, to be improved further annual a large amount of surgical linear Endo-GIA used in the world, the surgical effect of lighter when reaching use, more reliably, not reduce surgical linear Endo-GIA operation subject range.
Summary of the invention
The object of the invention is to the grip thickness governor motion proposing a kind of surgical linear Endo-GIA, realize when grip thickness adjusting slider is 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 nail anvil frame, the skewed slot of grip thickness adjusting slider is made to drive the arrowhead of slide bumping along nail anvil frame under the constraint of the arrowhead chute of nail anvil frame to move, both have adjusted 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, have adjusted again the distance between the briquetting on the projection of the grip thickness adjusting slider be arranged on nail-anvil assembly and the nail bin frame of nail bin groupware.Because the distance between the pivot hole on clamp hook and hook is constant, therefore grip thickness governor motion reaches the result of use of the thickness regulating the tissue between nail bin groupware and nail-anvil assembly to be clamped.Due to the nail anvil frame of grip thickness governor motion beyond nail anvil moving, the any position neither occupied in nail anvil does not change again the structure of nail anvil, therefore, when the thickness regulating the tissue between nail bin groupware and nail-anvil assembly to be clamped, the resistance be subject to is less, neither increase width and the height of nail anvil, rigidity and the intensity of nail anvil is not affected yet, more do not have the accessory structure of the tissue that can abrade surrounding, even if the used time is lighter, more reliably, do not reduce the operation subject range of surgical linear Endo-GIA, improve the surgical effect of engaging tissue.

Below in conjunction with Fig. 1 to Figure 21, the shape of the grip thickness governor motion of the surgical linear Endo-GIA of first embodiment of the invention and structure are described, the effect of grip thickness governor motion is described.
Surgical linear Endo-GIA 7 is made up of nail bin groupware 8, nail-anvil assembly 9 and grip thickness governor motion 10.As shown in Figures 1 to 6, surgical linear Endo-GIA 7 is in open configuration, clamp position and clamped condition respectively.
As shown in Figure 7, nail bin 11, the nail bin frame 12 installing nail bin 11 and the firing lock 13 be arranged in nail bin frame 12 is had in nail bin groupware 8.Ejector pin block (not shown) and anastomosis staple (not shown) are installed in nail bin 11.Multiple anastomosis staple is respectively staggered to two rows in the both sides of nail bin cutter groove 14.
As shown in Figure 10 to Figure 13, nail anvil 15 and nail anvil frame 16 is had in nail-anvil assembly 9.The surface of nail anvil 15 is arranged with the anastomosis staple grooving 17 corresponding with the anastomosis staple position in nail bin 11.Multiple anastomosis staple grooving 17 is respectively staggered to two rows in the both side surface of nail anvil cutter groove 18.
As shown in Fig. 7 to Figure 21, grip thickness governor motion 10 is made up of nail bin frame 12, nail anvil frame 16, clamp hook 19, grip thickness adjusting slider 20 and slide bumping 21.As shown in Figure 7, nail bin frame 12 there are pivot 22 and briquetting 23.As shown in Figure 8 and Figure 9, clamp hook 19 there are pivot hole 24 and hook 25.The pivot 22 of nail bin frame 12 inserts the pivot hole 24 of clamp hook 19, and formation clamp hook 19 is pivotally connected with nail bin frame 12.As is illustrated by figs. 11 and 12, nail anvil frame 16 has longitudinal chute 26 and arrowhead chute 27.As shown in figure 14, the near-end of grip thickness adjusting slider 20 has stairstepping projection 28, far-end has waveform skewed slot 29.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 shown in Fig. 7 to Figure 21, when grip thickness adjusting slider 20 under the constraint of longitudinal chute 26 of nail anvil frame 16 along the vertically moving of nail anvil frame 16 time, the stairstepping projection 28 of grip thickness adjusting slider 20 and waveform skewed slot 29, also along with vertically moving along nail anvil frame 16, make the waveform skewed slot skewed slot 29 of grip thickness adjusting slider 20 drive the arrowhead of slide bumping 21 along nail anvil frame 16 under the constraint of the arrowhead chute 27 of nail anvil frame 16 to move.Thus the distance between pivot 22 on the nail bin frame 12 of the projection 30 that both have adjusted on the slide bumping 21 that is arranged on nail-anvil assembly 9 and nail bin groupware 8, have adjusted again the distance between the briquetting 23 on the stairstepping projection 28 of the grip thickness adjusting slider 20 be arranged on nail-anvil assembly 9 and the nail bin frame 12 of nail bin groupware 8.
As shown in Figures 1 to 6, after nail bin groupware 8 and nail-anvil assembly 9 close up mutually, by clamp hook 19 around nail bin frame 12 pivot, the hook 25 on clamp hook 19 is made to hook projection 30 on slide bumping 21, drive the briquetting 23 on nail bin frame 12 to be pressed on the projection 30 on slide bumping 21, make nail bin groupware 8 and nail-anvil assembly 9 be clamped hook and clamp.
Because the distance between the pivot hole 24 on clamp hook 19 and hook 25 is constant, therefore grip thickness adjusting slider 20 have adjusted the thickness that the tissue between nail bin groupware 8 and nail-anvil assembly 9 is clamped.Fig. 3, Fig. 4, Fig. 6 and Figure 10 represent, surgical linear Endo-GIA 1 when nail bin groupware 8 is in thicker clamped condition with nail-anvil assembly 9, the mutual alignment of each part of grip thickness governor motion 10.Figure 16 to Figure 18 represents, surgical linear Endo-GIA 1 when nail bin groupware 8 mediates clamped condition with nail-anvil assembly 9, the mutual alignment of each part of grip thickness governor motion 10.Figure 19 to Figure 21 represents, surgical linear Endo-GIA 1 when nail bin groupware 8 is in thinner clamped condition with nail-anvil assembly 9, the mutual alignment of each part of grip thickness governor motion 10.
As shown in figure 15, slide bumping 21 is made up of balladeur train 31 and the round pin 32 be inserted on balladeur train 31.The arrowhead chute 27 that round pin 32 inserts nail anvil frame 16 is simultaneously interior with in the waveform skewed slot 29 of grip thickness adjusting slider 20, and the arrowhead that balladeur train 31 is constrained on along nail anvil frame 16 in nail-anvil assembly 9 moves.Balladeur train 31 is provided with spring 33.Spring 33 makes the round pin 32 on balladeur train 31 keep towards the arrowhead mobile trend in the face of the nail anvil 15 with anastomosis staple grooving 17.
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 has stepped skew 36.The cascaded surface of stairstepping projection 35 is plane.In the grip thickness governor motion 10 of this grip thickness adjusting slider 34 in surgical linear Endo-GIA 7, regulating the identical of nail bin groupware 8 and the effect be clamped between nail-anvil assembly 9 in the thickness organized and grip thickness adjusting slider 20.
Introduce known in detail according to above-mentioned, compared with existing various surgical linear Endo-GIA, 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, in order to reach the operation object of engaging tissue, the organization need to be anastomosed for different grip thickness uses the different anastomosis staple of nail lower limb height and the nail bin of differing heights.Due to be anastomosed organize not only soft but also flexible, be difficult to the thickness determining suitable anastomosed tissue, in operation, need to change the nail bin that the anastomosis staple of different nail lower limb height is housed selecting various grip thickness, generally be divided into a specification every the clamp tissue thickness of 0.5mm, add the cost of operation technique number of times and apparatus, therefore the surgical linear Endo-GIA of this style is difficult to the requirements of operation meeting various thickness tissue to be anastomosed, thus reduce surgical effect, add operating difficulty and operation cost.
Recently surgical linear Endo-GIA, grip thickness governor motion, when regulating grip thickness, needs the arrowhead position of regulating nail chopping block and pressing plate simultaneously.Wherein, when the arrowhead position of regulating nail chopping block, need a step-like adjustable plate to insert 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 elongate strip, when step-like adjustable plate inserts in nail anvil the arrowhead position of holding with the step-like nail anvil plate regulating nail chopping block of grooving, larger resistance can be subject to, be not easy to operation technique; Second, when step-like adjustable plate holds the step-like nail anvil plate with grooving, each stairstepping interval of adjustable plate and nail anvil plate forms larger cavity, thus when the grooving that the nail tip of anastomosis staple is pressed on nail anvil makes two to follow closely lower limbs along grooving bending forming, the active force produced can make nail anvil plate benging be out of shape, affect anastomosis staple to be correctly shaped, namely affect the surgical effect of engaging tissue; 3rd, in order to the arrowhead position making step-like adjustable plate hold the step-like nail anvil plate regulating nail chopping block with grooving, respectively have two guiding grooves in two sides of nail anvil, have the pin of arrowhead movement in guiding groove, the pin of this guiding groove and arrowhead movement can abrade the tissue of surrounding; 4th, because the clamp system of nail bin groupware and nail-anvil assembly is cantilever beam structure, adjustable plate and nail anvil plate occupy larger space in nail anvil, in order to make up the nail anvil rigidity being conditioned plate and nail anvil plate and weakening, add width and the height of nail anvil, both the weight having added nail anvil turn increases the volume of nail anvil, thus has both easily caused operation fatigue to additionally reduce 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 grip thickness adjusting slider is 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 nail anvil frame, the skewed slot of grip thickness adjusting slider is made to drive the arrowhead of slide bumping along nail anvil frame under the constraint of the arrowhead chute of nail anvil frame to move, both have adjusted 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, have adjusted again the distance between the briquetting on the projection of the grip thickness adjusting slider be arranged on nail-anvil assembly and the nail bin frame of nail bin groupware.Because the distance between the pivot hole on clamp hook and hook is constant, therefore grip thickness governor motion reaches the result of use of the thickness regulating the tissue between nail bin groupware and nail-anvil assembly to be clamped.If the step number of the skewed slot on grip thickness adjusting slider is more or wave number is more, the step number of the projection on grip thickness adjusting slider is more, then thickness adjustable separation number that the tissue between nail bin groupware and nail-anvil assembly is clamped is more.Due to the nail anvil frame of grip thickness governor motion beyond nail anvil moving, the any position neither occupied in nail anvil does not change again the structure of nail anvil, therefore, when the thickness regulating the tissue between nail bin groupware and nail-anvil assembly to be clamped, the resistance be 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 the tissue that can abrade surrounding.Compared with existing surgical linear Endo-GIA, lighter when surgical linear Endo-GIA of the present invention uses, more reliably, not reduce surgical linear Endo-GIA operation subject range, improves the surgical effect of engaging tissue.
The grip thickness governor motion of surgical linear Endo-GIA of the present invention, due in the arrowhead chute that the round pin of slide bumping inserts nail anvil frame and in the waveform skewed slot of grip thickness adjusting slider simultaneously, spring makes the round pin on balladeur train keep towards the arrowhead mobile trend in the face of the nail anvil with anastomosis staple grooving, thus make when grip thickness adjusting slider is along the vertically moving of nail anvil frame, under the waveform skewed slot of grip thickness adjusting slider and the effect of 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, continuous change grip thickness adjusting slider along nail anvil frame the resistance vertically moved and sound, compared with existing surgical linear Endo-GIA, surgical linear Endo-GIA of the present invention reaches grip thickness governor motion by there is sensation and the better result of use of the change of double-reminding operator grip thickness adjustment of sounding, on the other hand, grip thickness adjusting slider along nail anvil frame vertically move end after, under the waveform skewed slot of grip thickness adjusting slider and the effect of spring and under the constraint of the arrowhead chute of nail anvil frame, projection on slide bumping is fixed on regulated position, compared with existing surgical linear Endo-GIA, surgical linear Endo-GIA of the present invention reaches grip thickness governor motion and makes the tissue between nail bin groupware and nail-anvil assembly be fixed on better result of use on the position of regulated grip thickness.
Surgeon, when using surgical linear Endo-GIA of the present invention, organizes for the to be anastomosed of different grip thickness the nail bin not needing the anastomosis staple using different nail lower limb height, only need adopt the same nail bin of the anastomosis staple that identical nail lower limb height is housed.First by clamp tissue to be anastomosed between nail bin and nail anvil, if sensation grip thickness is improper, due to be clamped at the tissue regulated between nail bin groupware and nail-anvil assembly thickness time the grip thickness governor motion resistance that is subject to less, will not unclamp by surgical linear Endo-GIA, the nail bin groupware of surgical linear Endo-GIA and nail-anvil assembly is only needed to be in the clamp position shown in Fig. 2, namely directly the clamping gap between nail bin groupware and nail-anvil assembly can be regulated by grip thickness governor motion, when grip thickness governor motion regulates the clamping gap between nail bin groupware and nail-anvil assembly, grip thickness governor motion notices by generation sensation and the double-reminding operator that sound the change that grip thickness regulates, and then examination clamping tissue to be anastomosed, until satisfied, now, namely by firing lock, anastomosis staple is released in nail bin, make the nail tip of anastomosis staple penetrate clamped tissue to be anastomosed and direct reach grooving on nail anvil, reach the operation object of engaging tissue.When using in surgical operation, compared with existing surgical linear Endo-GIA, lighter during surgical linear Endo-GIA use of the present invention, more reliably, not reduce surgical linear Endo-GIA operation subject range, operating time is shorter, improves the surgical effect of engaging tissue.
So can find out, above-mentioned stated target, comprises by illustrating that those shown targets have been effectively achieved above.The typical best form of implementation of the present patent application that described here is only, can do some change also without prejudice to the spirit and scope of the present invention to said structure.The present invention is not limited to stated detail here, and should to retain as stated in the restriction of claim concerning affiliated field secondary technology personnel be apparent any improvement or remodeling.
