Abstract

A triggering mechanism of a surgery linear cutting anastomat achieves that two pushing buttons are respectively drawn on the left side of a nail container frame and the right side of the nail container frame. Not only can the pushing button on the left side of the nail container frame stretch to the left side of the nail container frame, but also the pushing button on the right side of the nail container frame can stretch to the right side of the nail container frame, and the two pushing buttons on the two sides of the nail container frame can respectively stretch to the left side of the nail container frame and the right side of the nail container frame. Therefore, when operation of clamping to-be-anastomosed tissue is conducted, the pushing buttons do not protrude to either side of the nail container frame, acting force exerted by an operation physician on a clamping hook is not influenced; when pushing button triggering operation is conducted, the operation physician can conveniently choose positions of the pushing buttons, and the acting force is exerted on the positions; the whole length is not increased, and operation effects in an operation adaptation range are not reduced.

[0004] 如美国专利公示20090308909中所介绍的:外科线形切割吻合器的击发机构的推钮位于钉仓组件的单侧。 [0004] U.S. Patent No. 20090308909 introduced in public: linear cutter surgical stapler the firing mechanism of the push button is located in one side of the staple cartridge assembly. 当击发机构的推钮推动滑块在钉仓架内向前移动时,滑块推动推杆在钉仓架内向前移动,推杆再推动推钉斜锲和切割刀在钉仓架内向前移动,推钉斜锲再依次推动各个推钉块将吻合钉从钉仓内推出。 When the firing mechanism of the push button pushes the slider is moved forward within the cartridge holder, the slider pushes the push rod is moved forward within the cartridge holder, and then push the push rod and wedge staple pushing helical cutting blade is moved forward within the cartridge holder, the staple pushing in turn push the respective inclined wedge staple pushing block within the staple out of the staple cartridge. 在钉仓内的吻合钉呈U形。 Staples within the staple cartridge U-shaped. 当推钉块将吻合钉从钉仓内推出,将U形的吻合钉的钉尖抵压在钉砧的成形槽上,使U形的吻合钉的两根钉腿沿着成形槽弯曲成B形的吻合钉,达到将组织吻合的手术目的。 When the push staples out of the staple block within the staple cartridge, the staples of the U-shaped nail tip pressed against the groove formed in the anvil, the U-shaped staple is bent along the two legs of the staple forming grooves to B shaped staples to achieve the purpose of the tissue at the surgical anastomosis. 为了保证达到将待吻合组织准确吻合的手术目的,击发机构的推钮在击发时需要不停顿地连续将80只左右的吻合钉从钉仓内推出,并使U形的吻合钉的两根钉腿沿着成形槽弯曲成B形的吻合钉,手术医师施加在推钮上的作用力是较大的。 In order to guarantee the achievement of the purpose of the operation to be accurate anastomosis stapling tissue, the firing mechanism of the push button needed without stopping the continuous left and right out of the staple 80 within the staple cartridge during firing, and the U-shaped staples of two nails B legs bent in a shape along the shaping grooves staples, the surgeon force exerted on the push button is relatively large. 这种式样的外科线形切割吻合器的击发机构的令人不满意处是:当钉仓组件与钉砧组件被夹紧钩夹紧将待吻合组织夹紧在钉砧和钉仓之间时,受待吻合组织的解剖位置的影响,单侧放置的推钮所在的位置可能不便于手术医师施加作用力在推钮,从而影响将待吻合组织准确吻合的手术目的。 Unsatisfactory at this style of a surgical linear cutting stapler firing mechanism is that: when the cartridge assembly and the anvil assembly is a clamping hook to be clamped when stapling tissue clamped between the anvil and the staple cartridge, affected anatomical location of tissue to be stapled, push button placed in the position of one side where the surgeon may not be easy to apply force in the push button, thus affecting the tissue to be stapled anastomosis accurate surgical purposes. 如美国专利公示20080116244中所介绍的:外科线形切割吻合器的击发机构的推钮可以绕安装在钉仓架内的滑块的枢轴转动。 U.S. Patent No. 20080116244 introduced in public: linear cutter surgical pivot slider stapler firing mechanism of the push button may be mounted within the staple cartridge about the frame rotation. 当推钮绕滑块的枢轴转动后,推钮既可以向钉仓架的左侧突出,也可以向钉仓架的右侧突出,便于手术医师选择施加作用力的推钮的位置。 When the push button to pivot about the slider, the push button may be protruded to the left of the staple cartridge holder and to be protruding to the right side of the cartridge holder, to facilitate surgeon select a location for urging the push button. 上述两种式样的外科线形切割吻合器的击发机构的令人不满意处是:由于击发机构的推钮始终向钉仓架的一侧突出,在夹紧钩绕钉仓架枢轴转动使得钉仓组件与钉砧组件被夹紧钩夹紧时,突出的推钮影响手术医师对夹紧钩施加作用力,从而影响将待吻合组织准确夹紧在钉砧和钉仓之间的操作,或引起手术医师的操作疲劳。 Shape unsatisfactory at both the linear cutter surgical stapler the firing mechanism is: Since the firing mechanism of the push button is always projecting to one side of the cartridge holder, the cartridge holder about a pivot axis such that rotation of the clamping hook staple when the cartridge assembly and the anvil assembly is clamped clamping hook, the push button projecting impact surgeon exerting a force on the clamping hook, thus affecting the accuracy to be stapled tissue clamped between the anvil and the staple cartridge of the operation, or causing operator fatigue of the surgeon. 如美国专利公示20110155787中所介绍的:外科线形切割吻合器的击发机构的推钮可以绕安装在钉仓架内的滑块的枢轴转动。 U.S. Patent No. 20110155787 introduced in public: linear cutter surgical pivot slider stapler firing mechanism of the push button may be mounted within the staple cartridge about the frame rotation. 当推钮绕滑块的枢轴转动后,推钮既可以向钉仓架的左侧突出,也可以向钉仓架的右侧突出。 When the push button to pivot about the slider, the push button may be protruded to the left of the staple cartridge holder and to be protruding to the right side of the cartridge holder. 由于推钮位于钉仓架的尾部,在夹紧待吻合组织的操作时,推钮不向钉仓架的任何一侧突出,不影响手术医师对夹紧钩施加作用力;在推钮击发操作时,又便于手术医师选择施加作用力的推钮的位置。 Since the push button is located in the tail of the cartridge holder when the clamping stapling tissue to be operated, the push button does not project from any side of the cartridge holder, the surgeon does not affect the clamping force is applied to the hook; firing operation in the push button , the surgeon select a location and easy to apply force to the push button. 这种式样的外科线形切割吻合器的击发机构的令人不满意处是:由于推钮位于钉仓架的尾部,增加了外科线形切割吻合器的整体长度,使得在某些解剖位置的待吻合组织没有足够的手术空间提供给外科线形切割吻合器操作。 Unsatisfactory at this style of a surgical linear cutting stapler firing mechanism is: Since the push button is located in the tail of the cartridge frame, increases the overall length of the cutter surgical stapler line, so to be stapled in certain anatomical site the organization does not have enough space to provide surgical cutting linear surgical stapler to operate. 上述三种式样的外科线形切割吻合器的击发机构的令人不满意处是:第一,由于推钮向钉仓架的单侧突出,当推钮击发时,手术医师仅能在外科线形切割吻合器的单侧施加作用力,对力气较小的手术医师,或对切割吻合阻力较大的手术部位,例如,切割吻合较厚或较硬的待吻合组织,或切割吻合上一次操作时该待吻合组织处的吻合钉,就难以达到将待吻合组织准确吻合的手术目的;第二,由于推钮向钉仓架的单侧突出,推钮突出部位离推钮与钉仓架内的滑块的力作用点较远,因此,推钮作用在滑块的力形成对切割吻合有用的推力和无用的扭矩,扭矩增加滑块与钉仓架之间的摩擦力和滑块的变形,从而增加击发机构的切割吻合阻力;第三,当推钮开始击发时,或当推钮完成击发时,或当推钮返回复位时,击发机构既无感觉、也无声音提醒手术操作人员 Shape unsatisfactory at the three linear cutter surgical stapler the firing mechanism are: first, since the push button protruding toward one side of the cartridge holder, when the push button is fired, the surgeon can only cut the surgical linear stapler unilateral force is applied, the smaller the strength of the surgeon, or when the cutting resistance is large anastomosis surgical site, e.g., cut and stapled thick or hard tissue to be stapled, the stapling operation or a cutting staples at the tissue to be stapled, it is difficult to achieve the object of the surgery will be accurate anastomosis stapling tissue; second, since the push button toward one side of the staple cartridge carrier protrude from the sliding portion of the push button protrudes inside the push button and the staple cartridge holder force block distant point, therefore, the push button action to form useful for cutting and stapling thrust unwanted torque increase in the torque force of the slider and the slider of the modification the friction between the slider and the cartridge holder, so that increasing cutting resistance stapling firing mechanism; third, when the push button to start the firing, or when the push button to complete the firing, or when the push button to return to the reset, the firing mechanism neither sense nor sound alert operator personnel 发过程的变化,从而可能引起击发机构操作失误。 Hair change process, which could lead to the firing mechanism operational errors. 因此外科线形切割吻合器的击发机构还需改进。 Therefore the linear cutter surgical stapler firing mechanism should be improved.

[0005] 由上述显然可以看出,现在已经设计了大量不同式样的外科线形切割吻合器,并且新的外科线形切割吻合器的击发机构的研制工作仍在继续,以便对每年世界上大量使用的外科线形切割吻合器作进一步的改进,达到使用时更方便、更省力、更可靠、更便于手术医师施加作用力和不减少外科线形切割吻合器的手术适应范围的手术效果。 [0005] As apparent from the above, have now devised a number of different styles of linear cutter surgical stapler, and new surgical linear cutter stapler firing mechanism of the development work is continuing to extensive use of annual world linear cutter surgical stapler more convenient for further improvement, to use, more effort, more reliable, easier to apply force and the surgeon does not reduce the linear cutter surgical stapler adaptation of the effect of surgery operation range. 发明内容 SUMMARY

[0013] 本发明的任务是通过下述技术方案实现的: [0013] The object of the invention is achieved by the following technical scheme:

[0014] 本发明的外科线形切割吻合器的击发机构由推钮、滑块、推杆、推钉斜锲和切割刀组成。 [0014] The linear surgical stapler according to the present invention, the cutter mechanism comprises a firing push button, slider, the push rod, and wedge staple pushing helical cutting blade composition. 两个推钮分别位于钉仓架的左右两侧。 Two right and left sides of the push button are located on the staple cartridge holder. 两个推钮分别有枢轴孔。 Two pivot holes, respectively, the push button. 滑块被约束在钉仓架内前后滑动。 The slider is constrained within the cartridge holder slide back and forth. 滑块中部有一个枢轴。 Slider has a central pivot. 两个推钮上下重叠放置后通过枢轴孔套在滑块的同一枢轴上。 After two push button on top of each pivot hole is placed through a pivot sleeve in the same slider. 两个推钮可以各自绕滑块的枢轴转动。 Two push button can each pivot about the slider. 当各个推钮绕滑块的枢轴转动后,推钮向钉仓架的外侧展开。 When the respective push button pivots about the slider, the push button outwardly to expand the cartridge holder. 既可以钉仓架左侧的推钮向钉仓架的左侧展开,也可以钉仓架右侦_推钮向钉仓架的右侧展开,还可以钉仓架两侧的两个推钮分别向钉仓架的左右两侧展开。 The cartridge holder may be left to expand the push button to the left of the cartridge holder, the cartridge holder may also detect the right _ push button to the right to expand the cartridge holder, the push button may be two sides of the cartridge holder left and right, respectively, to both sides of the staple cartridge holder. 当推钮推动滑块在钉仓架内向前移动时,滑块推动推杆在钉仓架内向前移动,推杆再推动推钉斜锲和切割刀在钉仓架内向前移动,推钉斜锲再依次推动各个推钉块将吻合钉从钉仓内推出。 When the push button pushes the slider is moved forward within the cartridge holder, the slider pushes the push rod is moved forward within the cartridge holder, and then push the push rod and wedge staple pushing helical cutting blade is moved forward within the cartridge holder, the staple push swash in turn pushing the respective wedge staple pushing block within the staple out of the staple cartridge.

[0015] 这样,两个推钮分别收拢在钉仓架的左右两侧,既可以钉仓架左侧的推钮向钉仓架的左侧展开,也可以钉仓架右侧的推钮向钉仓架的右侧展开,还可以钉仓架两侧的两个推钮分别向钉仓架的左右两侧展开。 [0015] Thus, two push button are folded on the sides of the staple cartridge holder, the cartridge may be left to expand to the left push button carrier cartridge holder may be a push button to the right of the staple cartridge holder expand the right side of the cartridge holder, the cartridge may also be two sides of the frame to both sides of the push button are left in the staple cartridge holder. 当推钮推动滑块在钉仓架内向前移动时,滑块推动推杆在钉仓架内向前移动,推杆再推动推钉斜锲和切割刀在钉仓架内向前移动,推钉斜锲再依次推动各个推钉块将吻合钉从钉仓内推出。 When the push button pushes the slider is moved forward within the cartridge holder, the slider pushes the push rod is moved forward within the cartridge holder, and then push the push rod and wedge staple pushing helical cutting blade is moved forward within the cartridge holder, the staple push swash in turn pushing the respective wedge staple pushing block within the staple out of the staple cartridge. 击发机构在夹紧待吻合组织的操作时,推钮不向钉仓架的任何一侧突出,不影响手术医师对夹紧钩施加作用力。 Firing mechanism during operation of stapling tissue to be clamped, the push button does not project from any side of the cartridge frame, does not affect the surgeon exerting a force on the clamping hook. 击发机构在推钮击发操作时,手术医师可以根据切割吻合待吻合组织的厚薄和软硬,或根据切割吻合上一次操作时该待吻合组织处是否有吻合钉,或根据手术医师的力气大小,选择单手或双手施加作用力的推钮的位置。 Firing the firing mechanism when the push button operation, surgical stapling physician may be cut according to the thickness and hardness stapling tissue, or once in accordance with the operation to be cut and stapled on whether the tissue at the anastomotic staples have, size or strength according to the surgeon, select one or both hands applying force to the push button position. 击发机构还达到不增加外科线形切割吻合器的整体长度,不减少外科线形切割吻合器的手术适应范围的手术效果。 The firing mechanism is also reached without increasing the overall length of the cutter surgical stapler, linear, linear surgical cutting procedure does not reduce the effect of the surgical stapler adaptation range.

[0016] 本发明的外科线形切割吻合器的两个推钮可以分别有枢轴孔和弧形槽,滑块远端可以有向钉仓架的左右两侧展开的翅。 [0016] The linear surgical stapler according to the present invention, the cutter may have a push button two pivot holes, respectively, and arcuate slots, the slider distal to the staple cartridge may have both right and left frame wings deployed. 当各个推钮绕滑块的枢轴转动后,推钮向钉仓架的外侧展开,推钮的弧形槽插在滑块的翅上,推钮通过弧形槽推动滑块的翅使得滑块在钉仓架内向前移动,滑块再推动推杆在钉仓架内向前移动,推杆再推动推钉斜锲和切割刀在钉仓架内向前移动,推钉斜锲再依次推动各个推钉块将吻合钉从钉仓内推出。 When the respective push button pivots about the slider, the push button outwardly to expand the cartridge holder, the push button is inserted in the arcuate groove of the wings of the slider, the push button by pushing the slider wings arcuate slot such that the slide block moves forward in the cartridge holder, then push the slider forward movement of the slide within the cartridge holder, and then push the push rod and wedge staple pushing helical cutting blade is moved forward within the cartridge holder, in turn push the staple pushing the respective wedge ramp pushing the staple out of the staple block within the staple cartridge.

[0017] 这样,由于推钮通过弧形槽推动滑块的翅使得滑块在钉仓架内向前移动,因此推钮突出部位离推钮与钉仓架内的滑块的力作用点较近,可以尽可能减少扭矩产生的滑块与钉仓架之间的摩擦力和滑块的变形,从而达到减少击发机构的切割吻合阻力的使用效果。 [0017] Thus, since the push button push slider so that the slider wings moved forward within the cartridge holder, away from the force so the push button in the push button slide and the cartridge holder portion protruding through arcuate slot points nearer , the torque can be reduced as much as possible the deformation of the friction between the slider and the slider and the staple cartridge carrier generated, so as to achieve reduction of the firing mechanism of the cutting resistance consistent results. [0018] 滑块的枢轴近侧可以有滑槽。 [0018] The proximal slider may have pivot the chute. 两个推钮可以分别有凸块。 Two push button may have bumps, respectively. 钉仓架的近端的左右两侧可以分别有缺口。 The left and right sides of the proximal end of the cartridge frame may be notched respectively. 当各个推钮靠拢钉仓架的侧面时,推钮的凸块位于滑块的滑槽内。 When the push button to move closer to the respective side surface of the cartridge holder, the push button bumps positioned within the slider chute. 当各个推钮绕滑块的枢轴转动向钉仓架的外侧展开时,推钮的凸块从钉仓架的缺口处移出滑块的枢轴近侧的滑槽并靠在钉仓架的侧面上。 When each of the push button to pivot about the slider outward to expand the cartridge holder, the push button bumps proximal the chute pivots from the break out of the cartridge holder against the slider and the cartridge holder on the side. 当推动向钉仓架的外侧展开的推钮向前移动时,向钉仓架的外侧展开的推钮推动滑块在钉仓架内向前移动,未向钉仓架的外侧展开的推钮的凸块则被钉仓架约束在滑块的枢轴近侧的滑槽内向前移动。 When pushed outwardly deployed staple cartridge frame forward movement of the push button, to expand the outer frame of the staple cartridge pusher pushes the slider is moved forward within the cartridge holder, the cartridge does not expand to the outside of the frame of the push button the cartridge holder projections were constrained to move forward in the chute pivots the proximal slider. 当向钉仓架的外侧展开的推钮向后移动时,向钉仓架的外侧展开的推钮的凸块靠在钉仓架的侧面上,阻止推钮绕滑块的枢轴转动,从而使得向钉仓架的外侧展开的推钮带动滑块在钉仓架内向后移动。 When deployed to the outside of the staple cartridge holder push button is moved backward, the staple cartridge expanded outward push button frame bumps against the side surface of the cartridge frame, preventing the push button to pivot about the slider, so that such that the outer frame of the staple cartridge pusher deployed rearward in the drive slider cartridge holder.

[0069] 根据上述详细介绍可知,与现有的各种外科线形切割吻合器相比较,本发明的外科线形切割吻合器的击发机构具有如下技术效果: [0069] The foregoing detailed description be seen, cutting stapler as compared with the conventional variety of surgical linear, linear surgical stapler of the present invention cutter firing mechanism has the following technical effects:

[0070] 现有的一些外科线形切割吻合器的击发机构的推钮位于钉仓组件的单侧。 [0070] Some conventional linear cutter surgical stapler the firing mechanism of the push button located on one side of the cartridge assembly. 当击发机构的推钮推动滑块在钉仓架内向前移动时,滑块推动推杆在钉仓架内向前移动,推杆再推动推钉斜锲和切割刀在钉仓架内向前移动,推钉斜锲再依次推动各个推钉块将吻合钉从钉仓内推出。 When the firing mechanism of the push button pushes the slider is moved forward within the cartridge holder, the slider pushes the push rod is moved forward within the cartridge holder, and then push the push rod and wedge staple pushing helical cutting blade is moved forward within the cartridge holder, the staple pushing in turn push the respective inclined wedge staple pushing block within the staple out of the staple cartridge. 在钉仓内的吻合钉呈U形。 Staples within the staple cartridge U-shaped. 当推钉块将吻合钉从钉仓内推出,将U形的吻合钉的钉尖抵压在钉砧的成形槽上,使U形的吻合钉的两根钉腿沿着成形槽弯曲成B形的吻合钉,达到将组织吻合的手术目的。 When the push staples out of the staple block within the staple cartridge, the staples of the U-shaped nail tip pressed against the groove formed in the anvil, the U-shaped staple is bent along the two legs of the staple forming grooves to B shaped staples to achieve the purpose of the tissue at the surgical anastomosis. 为了保证达到将待吻合组织准确吻合的手术目的,击发机构的推钮在击发时需要不停顿地连续将80只左右的吻合钉从钉仓内推出,并使U形的吻合钉的两根钉腿沿着成形槽弯曲成B形的吻合钉,手术医师施加在推钮上的作用力是较大的。 In order to guarantee the achievement of the purpose of the operation to be accurate anastomosis stapling tissue, the firing mechanism of the push button needed without stopping the continuous left and right out of the staple 80 within the staple cartridge during firing, and the U-shaped staples of two nails B legs bent in a shape along the shaping grooves staples, the surgeon force exerted on the push button is relatively large. 这种式样的外科线形切割吻合器的击发机构的令人不满意处是:当钉仓组件与钉砧组件被夹紧钩夹紧将待吻合组织夹紧在钉砧和钉仓之间时,受待吻合组织的解剖位置的影响,单侧放置的推钮所在的位置可能不便于手术医师施加作用力在推钮,从而影响将待吻合组织准确吻合的手术目的。 Unsatisfactory at this style of a surgical linear cutting stapler firing mechanism is that: when the cartridge assembly and the anvil assembly is a clamping hook to be clamped when stapling tissue clamped between the anvil and the staple cartridge, affected anatomical location of tissue to be stapled, push button placed in the position of one side where the surgeon may not be easy to apply force in the push button, thus affecting the tissue to be stapled anastomosis accurate surgical purposes. 现有的另一些外科线形切割吻合器的击发机构的推钮可以绕安装在钉仓架内的滑块的枢轴转动。 Pivot slide other conventional push button linear cutter surgical stapler the firing mechanism may be mounted within the staple cartridge about the frame rotation. 当推钮绕滑块的枢轴转动后,推钮既可以向钉仓架的左侧突出,也可以向钉仓架的右侧突出,便于手术医师选择施加作用力的推钮的位置。 When the push button to pivot about the slider, the push button may be protruded to the left of the staple cartridge holder and to be protruding to the right side of the cartridge holder, to facilitate surgeon select a location for urging the push button. 上述两种式样的外科线形切割吻合器的击发机构的令人不满意处是:由于击发机构的推钮始终向钉仓架的一侧突出,在夹紧钩绕钉仓架枢轴转动使得钉仓组件与钉砧组件被夹紧钩夹紧时,突出的推钮影响手术医师对夹紧钩施加作用力,从而影响将待吻合组织准确夹紧在钉砧和钉仓之间的操作,或引起手术医师的操作疲劳。 Shape unsatisfactory at both the linear cutter surgical stapler the firing mechanism is: Since the firing mechanism of the push button is always projecting to one side of the cartridge holder, the cartridge holder about a pivot axis such that rotation of the clamping hook staple when the cartridge assembly and the anvil assembly is clamped clamping hook, the push button projecting impact surgeon exerting a force on the clamping hook, thus affecting the accuracy to be stapled tissue clamped between the anvil and the staple cartridge of the operation, or causing operator fatigue of the surgeon. 现有的还有一些外科线形切割吻合器的击发机构的推钮可以绕安装在钉仓架内的滑块的枢轴转动。 Pivot slide some conventional linear cutter surgical stapler the firing mechanism of the push button may be mounted within the staple cartridge about the frame rotation. 当推钮绕滑块的枢轴转动后,推钮既可以向钉仓架的左侧突出,也可以向钉仓架的右侧突出。 When the push button to pivot about the slider, the push button may be protruded to the left of the staple cartridge holder and to be protruding to the right side of the cartridge holder. 由于推钮位于钉仓架的尾部,在夹紧待吻合组织的操作时,推钮不向钉仓架的任何一侧突出,不影响手术医师对夹紧钩施加作用力;在推钮击发操作时,又便于手术医师选择施加作用力的推钮的位置。 Since the push button is located in the tail of the cartridge holder when the clamping stapling tissue to be operated, the push button does not project from any side of the cartridge holder, the surgeon does not affect the clamping force is applied to the hook; firing operation in the push button , the surgeon select a location and easy to apply force to the push button. 这种式样的外科线形切割吻合器的击发机构的令人不满意处是:由于推钮位于钉仓架的尾部,增加了外科线形切割吻合器的整体长度,使得在某些解剖位置的待吻合组织没有足够的手术空间提供给外科线形切割吻合器操作。 Unsatisfactory at this style of a surgical linear cutting stapler firing mechanism is: Since the push button is located in the tail of the cartridge frame, increases the overall length of the cutter surgical stapler line, so to be stapled in certain anatomical site the organization does not have enough space to provide surgical cutting linear surgical stapler to operate. 上述三种式样的外科线形切割吻合器的击发机构的令人不满意处是:第一,由于推钮向钉仓架的单侧突出,当推钮击发时,手术医师仅能在外科线形切割吻合器的单侧施加作用力,对力气较小的手术医师,或对切割吻合阻力较大的手术部位,例如,切割吻合较厚或较硬的待吻合组织,或切割吻合上一次操作时该待吻合组织处的吻合钉,就难以达到将待吻合组织准确吻合的手术目的;第二,由于推钮向钉仓架的单侧突出,推钮突出部位离推钮与钉仓架内的滑块的力作用点较远,因此,推钮作用在滑块的力形成对切割吻合有用的推力和无用的扭矩,扭矩增加滑块与钉仓架之间的摩擦力和滑块的变形,从而增加击发机构的切割吻合阻力;第三,当推钮开始击发时,或当推钮完成击发时,或当推钮返回复位时,击发机构既无感觉、也无声音提醒手术操作人员 Shape unsatisfactory at the three linear cutter surgical stapler the firing mechanism are: first, since the push button protruding toward one side of the cartridge holder, when the push button is fired, the surgeon can only cut the surgical linear stapler unilateral force is applied, the smaller the strength of the surgeon, or when the cutting resistance is large anastomosis surgical site, e.g., cut and stapled thick or hard tissue to be stapled, the stapling operation or a cutting staples at the tissue to be stapled, it is difficult to achieve the object of the surgery will be accurate anastomosis stapling tissue; second, since the push button toward one side of the staple cartridge carrier protrude from the sliding portion of the push button protrudes inside the push button and the staple cartridge holder force block distant point, therefore, the push button action to form useful for cutting and stapling thrust unwanted torque increase in the torque force of the slider and the slider of the modification the friction between the slider and the cartridge holder, so that increasing cutting resistance stapling firing mechanism; third, when the push button to start the firing, or when the push button to complete the firing, or when the push button to return to the reset, the firing mechanism neither sense nor sound alert operator personnel 击发过程的变化,从而可能引起击发机构操作失误。 Changes in the firing process, which may cause the firing mechanism operational errors. 因此现有的外科线形切割吻合器的击发机构还需改进。 Thus the conventional linear cutter surgical stapler firing mechanism should be improved.

[0071] 本发明的外科线形切割吻合器的击发机构的两个推钮各自绕滑块的枢轴转动。 [0071] The linear surgical stapler according to the present invention, the cutter mechanism of the firing push button two respective pivot about the slider. 当各个推钮绕滑块的枢轴转动后,推钮向钉仓架的外侧展开。 When the respective push button pivots about the slider, the push button outwardly to expand the cartridge holder. 既可以钉仓架左侧的推钮向钉仓架的左侧展开,也可以钉仓架右侧的推钮向钉仓架的右侧展开,还可以钉仓架两侧的两个推钮分别向钉仓架的左右两侧展开。 The cartridge holder may be left to expand the push button to the left of the cartridge holder, the staple may be a push button on the right side of the cartridge holder to the right to expand the cartridge holder, the push button may be two sides of the cartridge holder left and right, respectively, to both sides of the staple cartridge holder. 当推钮推动滑块在钉仓架内向前移动时,滑块推动推杆在钉仓架内向前移动,推杆再推动推钉斜锲和切割刀在钉仓架内向前移动,推钉斜锲再依次推动各个推钉块将吻合钉从钉仓内推出。 When the push button pushes the slider is moved forward within the cartridge holder, the slider pushes the push rod is moved forward within the cartridge holder, and then push the push rod and wedge staple pushing helical cutting blade is moved forward within the cartridge holder, the staple push swash in turn pushing the respective wedge staple pushing block within the staple out of the staple cartridge. 与现有的外科线形切割吻合器相比较,本发明的外科线形切割吻合器的击发机构达到既在夹紧待吻合组织的操作时,推钮不向钉仓架的任何一侧突出,不影响手术医师对夹紧钩施加作用力;又在推钮击发操作时,手术医师还可以根据切割吻合待吻合组织的厚薄和软硬,或根据切割吻合上一次操作时该待吻合组织处是否有吻合钉,或根据手术医师的力气大小,选择单手或双手施加作用力的推钮的位置;还不增加外科线形切割吻合器的整体长度,不减少外科线形切割吻合器的手术适应范围的手术效果。 Cutting stapler as compared with the conventional surgical linear, linear surgical stapler of the present invention cutter mechanism to achieve both a firing operation during clamping tissue to be stapled, push button to either side of the cartridge without protruding frame, does not affect surgeon exerting a force on the clamping hook; when the push button and firing operation, the surgeon may also be consistent thickness and hardness on the cutting stapling tissue, or the tissue to be stapled at once according to whether the anastomosis stapling operation on a cutting nails, size or strength according to the surgeon to select the position of one or both hands applying force to the push button; not increasing the overall length of the linear cutter surgical stapler, without reducing the linear cutter surgical stapler adaptation range of surgical effect of surgery .

[0072] 本发明的外科线形切割吻合器的击发机构的两个推钮分别有枢轴孔和弧形槽,滑块远端有向钉仓架的左右两侧展开的翅。 [0072] The present invention is a surgical linear cutting stapler firing mechanism of the push button, respectively, two pivot holes and arcuate slots, the slider has a distal end to expand the cartridge both the left and right wing frame. 当各个推钮绕滑块的枢轴转动后,推钮向钉仓架的外侧展开,推钮的弧形槽插在滑块的翅上,推钮通过弧形槽推动滑块的翅使得滑块在钉仓架内向前移动,滑块再推动推杆在钉仓架内向前移动,推杆再推动推钉斜锲和切割刀在钉仓架内向前移动,推钉斜锲再依次推动各个推钉块将吻合钉从钉仓内推出。 When the respective push button pivots about the slider, the push button outwardly to expand the cartridge holder, the push button is inserted in the arcuate groove of the wings of the slider, the push button by pushing the slider wings arcuate slot such that the slide block moves forward in the cartridge holder, then push the slider forward movement of the slide within the cartridge holder, and then push the push rod and wedge staple pushing helical cutting blade is moved forward within the cartridge holder, in turn push the staple pushing the respective wedge ramp pushing the staple out of the staple block within the staple cartridge. 与现有的外科线形切割吻合器相比较,由于本发明的外科线形切割吻合器的击发机构的推钮通过弧形槽推动滑块的翅使得滑块在钉仓架内向前移动,因此推钮突出部位离推钮与钉仓架内的滑块的力作用点较近,可以尽可能减少扭矩产生的滑块与钉仓架之间的摩擦力和滑块的变形,从而达到减少击发机构的切割吻合阻力的使用效果。 Cutting stapler as compared with the conventional linear surgical, since the present invention is linear cutter surgical stapler the firing mechanism through an arcuate slot push button push slider wings so that the slider moves forward within the cartridge holder, and therefore the push button force application point portion projecting from the slide in the push button and the cartridge holder close, the deformation can reduce the friction between the slider and the slider of the carrier and the staple cartridge as the torque generated, thus to decrease the firing mechanism stapling cutting resistance results.
