[0004] 外科线形切割缝合器的执行头的组成部分包括:钉仓和钉砧。 [0004] The components of the linear cutter surgical stapler end effector comprises: a staple cartridge and the anvil. 钉仓由钉仓壳、推钉块和缝合钉组成。 Staple cartridge housing a staple cartridge, staples and staple pushing block composition. 钉仓壳内有钉槽、推钉孔和推刀槽。 Staple cartridge housing groove, and push the staple pushing hole sipe. 缝合钉呈U形,由两个钉腿、一个钉梁和两个钉尖组成。 U-shaped staples, the two staple legs, and a staple beams composed of two nail tip. 钉腿的一端分别与钉梁连接、另一端分别为钉尖。 One end of the staple legs are connected to the beams staple, the other end of the nail tip. 缝合钉可采用不锈钢丝、钽丝、钛丝或其它具有类似性能的金属丝制造。 Staple wire can be stainless steel, tantalum wire, titanium wire or other metal wire manufactured having similar properties. 缝合钉的两个钉腿插在钉槽内。 Two staples in the staple staple legs interposed slots. 缝合钉的钉梁坐在推钉块的上边上。 Staple staple staple pushing beam sitting on the edge of the block. 推钉块可在推钉孔内移动以便将缝合钉从钉槽内推出。 The staple pushing block so as to be pushed out of the staple slots of the staple pushing the staple is moved in the bore. 钉砧的端面上有与钉仓内的缝合钉位置对应的缝合钉成形槽和与钉仓内的推刀槽位置对应的切割槽。 It has an end surface and the anvil staple position corresponding staple forming grooves in the staple cartridge and the staple cartridge to push the inner sipe cutting position corresponding to the groove. 钉仓的钉槽排列在钉仓的推刀槽的两侧,钉砧的缝合钉成形槽相应排列在钉砧的切割槽的两侧。 Sipe push both sides of the staple slots of the staple cartridge are arranged in a staple cartridge, the anvil staple forming grooves are arranged on both sides of the respective anvil cutting groove. 钉仓的钉槽和钉砧的缝合钉成形槽可以根据外科手术对切割缝合的需要,分别排列成两排、三排、四排、五排或六排。 Staple cartridge staple slots and the anvil staple forming grooves can be cut stapled, surgical are arranged in two rows, three rows, four rows, six rows, or five rows. 推钉板和切割刀既可以安装在钉仓内,也可以安装在外科线形切割缝合器的其它部件内。 The staple pushing plate and the cutting blade can be mounted either within the cartridge, may be installed in other parts of a linear cutter surgical stapler. 推钉板依靠斜面推动推钉块将缝合钉从钉仓的钉槽内推出。 The staple pushing plate depend on the slant pushing the push block staples staples out of the staple slots of the staple cartridge. 根据推钉块推出缝合钉时的受力变化,现有的推钉板的斜面的前半段的斜角较大,后半段的斜角较小。 Release of the force when the staple The staple pushing block changes, the bevel angle of the first half of a conventional staple pushing plate is large, a smaller angle of the second half. 切割刀在钉仓的推刀槽内移动。 Moving the cutting blade in the blade pushing the staple cartridge slot.

[0005] 如美国专利20070045379和20070194082中所介绍的,外科线形切割缝合器和腔镜外科线形切割缝合器的钉仓内的U形缝合钉的两个钉腿插在钉槽内,缝合钉的钉梁坐在推钉块的上边上,推钉块和推钉孔相配合的两个侧面呈棱形,推钉孔贯通钉仓,推钉块在推钉孔内移动以便将缝合钉从钉槽内推出。 [0005] U.S. Patent No. 20070045379 and 20070194082 introduced, linear surgical staplers and endoscopic surgical cutting line U-shaped staple in the staple cartridge of the stapler is inserted in the two legs of the staple slots staples, staple beam staple staple pushing block sitting on the edge of two sides of the block and push the staple pushing nail holes mating prismatic shape, staple pushing hole penetrating a staple cartridge, staple pushing block is moved in the hole in order to push the staples staples from the staple slots available. 这两种式样的外科线形切割缝合器的钉仓的令人不满意处是,由于U形缝合钉的两个钉腿插在钉槽内,缝合钉的钉梁坐在推钉块的上边上,使得U形缝合钉在朝向钉槽口的方向无任何约束,又由于推钉孔贯通钉仓,推钉块又可在推钉孔内移动,在装配、检验、包装、消毒、运输和外科手术使用过程中,外科线形切割缝合器的钉仓内的几十只缝合钉或推钉块中有可能会丢失几只,只要丢失一只缝合钉或推钉块,则在该位置处没有将组织缝合,会发生出血和泄漏等手术事故,因此在每一过程中应该认真检查钉仓内的几十只缝合钉和推钉块,不可丢失一只,实际上仅在装配和检验过程中可以实施,在包装、消毒和运输过程中无法实施,在外科手术使用过程中即使发现也无法添加适用的缝合钉或推钉块。 These two designs are unsatisfactory at the linear surgical stapler the staple cartridge, since the two U-shaped staple staple staple legs interposed slots, staple staple staple pushing beam sitting on the edge of the block , so that the U-shaped staple without any constraints in the direction toward the staple slot, and because the staple pushing hole penetrating a staple cartridge, the staple pushing block is moved in turn staple pushing hole, assembly, inspection, packaging, sterilization, transport and surgical use surgical procedure, the surgical staple or dozens linear staple pushing block within the stapler staple cartridge may be lost in a few, as long as the loss of a staple or staple pushing block is not at this position will tissue suture, surgical bleeding and leakage accident occur and should therefore be carefully examined dozens of staples in the staple cartridge and the staple pushing blocks in each process, not a loss, in fact, only in the assembly and testing process embodiment, can not be implemented in the packaging, sterilization and transportation process, the course of the surgery can not be found even add suitable staple or nail pushing block. 这两种式样的外科线形切割缝合器的钉仓的另一令人不满意处是,由于在推钉块将缝合钉从钉仓内推出穿透被夹紧的待切割缝合组织的同时切割刀切割被夹紧的待切割缝合组织,U形缝合钉在朝向钉槽口的方向又无任何约束,因此被切开的组织收缩时牵拉缝合钉,使缝合钉的位置偏移,造成缝合钉无法正确地直抵钉砧上的缝合钉成形槽,使U形缝合钉无法正确地弯曲成B形,则在该位置处没有将组织正确地缝合,会发生出血和泄漏等手术事故。 Another unsatisfactory at both style linear surgical stapler the staple cartridge, because the push staples out of the staple block within the staple cartridge to penetrate the clamped tissue to be cut while the suture cutting blade the direction of cutting the tissue to be clamped stapler, U-shaped staples toward the staple slot nor any constraints, so the contraction of the tissue is cut when the staple is pulled, so that the staple position shift, resulting in staple not correctly straight staples on the anvil staple forming grooves, the U-shaped staple can not be accurately bent to form B, the tissue is not properly sutured at this position, surgical bleeding and leakage accident occurs. 这两种式样的外科线形切割缝合器的钉仓的再一令人不满意处是,推钉块和推钉孔相配合的两个侧面呈棱形,由于推钉块和推钉孔的棱形侧面仅有0. 3mm 至0. 8mm宽,其加工精度难以保证,因此,为了保证推钉块在推钉孔内定位正确,在推钉块的两个侧面加工有0. 3mm左右宽的长筋条,装配时将长筋条插入钉槽内,这种结构既增加了加工难度,又大大增加了推钉块在推钉孔内移动时的阻力,并且在推钉板依靠斜面推动推钉块将缝合钉从钉仓内推出的过程中,推钉块侧向受力,推钉块的棱形侧面呈锲状挤压钉槽,钉槽发生弹性变形,进一步增加了推钉块在推钉孔内移动时的阻力。 A further unsatisfactory at both style linear surgical stapler the staple cartridge, the two sides and push the staple pushing block form prism cooperating nail holes, since the staple pushing block and rib push the nail holes shaped side only 0. 3mm to 0. 8mm wide, the machining accuracy is difficult to ensure, therefore, in order to ensure the staple pushing block staple pushing hole is correctly positioned on both sides of the staple pushing block processing has about 0. 3mm wide long rib, the length of the assembly bars inserted into the staple slots, this structure not only increases the difficulty of processing, but also greatly increasing the resistance when the staple pushing block bore staple pushing movement, the inclined surface and rely on pushing the push plate pushing the nail process block staple staples introduced from the staple cartridge, the staple pushing block lateral forces, the side prismatic wedge staple pushing block shaped as a staple pressing groove, the groove is elastically deformed staple, the staple pushing block further increases in the staple pushing hole resistance during movement.

[0006] 为了防止钉仓内的几十只缝合钉和推钉块在装配、检验、消毒、运输和外科手术使用过程中被丢失,美国专利7055730和20080116M4中介绍的外科线形切割缝合器和美国专利20090095790中介绍的腔镜外科线形切割缝合器,采用在钉仓的上表面盖上一块在使用时移去的防护板,在钉仓的下底面装上一块衬板。 [0006] In order to prevent dozens of staples and the staple cartridge in the staple pushing block assembly, inspection, sterilization, transport and use of the surgical procedure being lost, the surgical linear U.S. Patent 7,055,730 and 20080116M4 stapler described in United States Patent 20090095790 endoscopic surgical linear stapler described in, employed on the surface of a cover of the staple cartridge removed in use shielding plate, mounted on the bottom surface of a staple cartridge liner. 这两种式样的外科线形切割缝合器的钉仓的令人不满意处一是需要增加零件;二是只能保证在装配、检验、包装、消毒和运输过程中钉仓内的缝合钉和推钉块不会丢失,但不能保证在这些过程中钉仓内的缝合钉不移位,也不能保证在外科手术使用过程中钉仓内的缝合钉不会丢失。 These two designs are unsatisfactory at the linear surgical stapler the staple cartridge of one part needs to be increased; the second is to ensure that only during assembly, inspection, packaging, sterilization and transportation and push staple within staple cartridge staple block is not lost, but can not guarantee the staple within staple cartridge is not displaced in these processes, there is no guarantee in the staple cartridge is not lost during surgical use.

[0007] 为了防止被切开的组织收缩时牵拉缝合钉造成缝合钉的位置偏移,使缝合钉无法正确成形,美国专利20060180633中介绍的外科线形切割缝合器采用两个钉腿一个长、一个短的U形缝合钉,当推钉块将缝合钉从钉仓内推出时,位于前方的长的钉腿先穿透被夹紧的待切割缝合组织直抵钉砧上的缝合钉成形槽弯曲后钩住待切割缝合组织,以防止被切开的组织收缩时牵拉缝合钉造成缝合钉的位置偏移。 [0007] In order to prevent pulling the staple position causes displacement staple severed tissue when contraction of the staple can not be properly formed, U.S. Patent 20060180633 surgical linear stapler described using a two long staple legs, a short U-shaped staple, when the push staples out of the staple block within the staple cartridge, positioned in front of the first long staple legs penetrate the clamped tissue to be cut straight staple on the stapling anvil forming curved slot after hooking stapling tissue to be cut, in order to prevent pulling the staple staple position offset caused when the severed tissue contraction. 这种式样的外科线形切割缝合器的钉仓的令人不满意处一是两个钉腿一个长、一个短的U形缝合钉的成形质量较差;二是U形缝合钉有方向性,给加工和装配带来许多困难,一旦装配的方向错误,产生的效果正好相反; 三是长的钉腿加大了U形缝合钉的尺寸,使得推钉块和推钉板的尺寸也随着增加,钉仓的尺寸更是双重增加,减少了外科线形切割缝合器的手术适用范围。 This style linear surgical stapler the staple cartridge at one of two unsatisfactory long staple legs a poor forming quality of a short U-shaped staple; two U-shaped staple directional, for processing and assembly caused many difficulties, once the direction of errors in the assembly, to produce the opposite effect; Third long staple legs to increase the size of the U-shaped staple, so that the size of the staple pushing block and the staple pushing plate along with increases, the size of the cartridge is a double increase, reducing the linear cutter surgical scope surgical stapler.

[0008] 因此外科线形切割缝合器的钉仓还需改进。 [0008] Thus the linear surgical stapler the staple cartridge should be improved. [0009] 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缝合器的钉仓,并且新的外科线形切割缝合器的钉仓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缝合器的钉仓作进一步的改进,使得使用时更方便、更准确、更省力、更安全,装配检验时更便利,生产成本更低。 [0009] As apparent from the above, have now devised a number of different styles of surgical linear stapler of the staple cartridge, and new surgical linear stapler of the staple cartridge development work continues, in order to the world each year more convenient to use a large number of the linear surgical stapler the staple cartridge further improvements, so that the use of more accurate, and more labor-saving, safer, more convenient test assembly, lower cost of production.

[0035] 根据上述详细介绍可知,本发明的外科线形切割缝合器的钉仓具有如下技术效果: [0035] The foregoing detailed description be seen, the present invention is a linear surgical stapler having a staple cartridge following technical effects:

[0036] 本发明的外科线形切割缝合器的钉仓内的U形缝合钉的钉梁被部分伸入缝合钉沿钉仓壳内的钉槽移动的途径内的推钉块的约束钩约束在推钉槽内,缝合钉的两个钉腿又被约束在钉仓壳的钉槽内,使得缝合钉在朝向钉槽口的钉仓壳的上端面的方向的移动受到推钉块的约束。 Constraint constraint hook staple pushing block within the route [0036] The present invention is linear surgical U-shaped staples in the stapler of the staple cartridge beam projecting into the staple cartridge in the staple housing staple slot portion moves staple pushing slot, two staples are constrained Tuiyou staples in the staple slots of the staple cartridge housing, such that the staple to be bound by the staple pushing block is moved in the direction toward the upper end of the staple slots of the staple cartridge housing. 又由于钉仓内的钉槽从钉仓壳的推钉孔的上端面延伸到安装在钉仓壳的推钉孔内的推钉块的推钉槽处,使得缝合钉和推钉块在朝向钉槽口的钉仓壳的上端面的相反方向的移动受到钉仓壳的钉槽的约束。 Also, because the staple within staple cartridge channel extending from the upper end surface of the staple pushing the staple cartridge housing aperture to push the staple slots of the staple pushing block is mounted on the staple push the staple cartridge housing aperture so that the staples and staple pushing block toward restrict movement in the opposite direction on the end surface of the staple slots of the staple cartridge housing of the cartridge by the staple housing staple slot. 因此,缝合钉和推钉块只有在朝向钉槽口的钉仓壳的上端面的方向的共同移动未受到钉仓壳的约束。 Thus, the common staple and staple pushing movement only in the block toward the staple slots of the staple cartridge housing end surface direction of the cartridge shell is not subject to constraints. 由于推钉块的体积较大,推钉块和推钉孔形状较复杂,推钉块离钉仓壳的上端面的距离又较远,使得推钉块在推钉孔内移动时受到的阻力较大,在无外力直接作用在推钉块上时,质量远小于推钉块的缝合钉很难牵拉推钉块一起脱离钉仓壳,从而可以防止钉仓内的几十只缝合钉和推钉块在装配、检验、消毒、 运输和外科手术使用过程中被丢失。 Due to the large volume of the staple pushing block, the block and push the staple pushing nail holes complicated shape, staple pushing block away from the staple cartridge housing and the upper end surface distant, so that the resistance by the staple pushing block is moved while pushing the staple bore large, when no external force directly acts on the staple pushing block mass is much smaller than the staple pushing block staple staple pushing block is difficult to pull out the staple cartridge housing together, thereby preventing dozens staple cartridge and the staple the staple pushing block assembly, inspection, sterilization, transport and use of the surgical procedure being lost. 另一方面,由于缝合钉在朝向钉槽口的钉仓壳的上端面的方向的移动受到推钉块的约束,只有当推钉板推动推钉块将缝合钉从钉仓内推出直至缝合钉的两个钉腿脱离钉仓壳的钉槽的约束,缝合钉才能脱离推钉块的约束,此时,缝合钉的钉腿已穿透被夹紧的待切割缝合组织、直抵钉砧上的缝合钉成形槽弯曲后钩住待切割缝合组织,从而可以在推钉块将缝合钉从钉仓内推出穿透被夹紧的待切割缝合组织直抵钉砧上的缝合钉成形槽的过程中,防止被切开的组织收缩时牵拉缝合钉偏斜所造成的缝合钉成形失常,避免因没有将组织正确缝合而发生出血和泄漏的手术事故。 On the other hand, since the staple staple pushing block restrained in movement direction toward the end surface of the staple cartridge housing slot, only when the staple pushing plate to push the push block staple staple staple from launch until the staple cartridge constraints two staple legs departing from the staple cartridge housing staple slot, the staples to push the staples out of the constraint block, this time, the staple has penetrated the staple legs to be cut stapling the clamped tissue, leading to the anvil after staple bending groove formed staple tissue to be cut is hooked, so that staples can be launched from within the staple cartridge in the staple pushing block during the staple penetration stapling the clamped tissue to be cut straight staple forming grooves in the anvil, preventing deflection caused by pulling the staple forming malfunction staple severed tissue when contraction, avoiding accidents caused no tissue surgical suturing correctly bleeding and leakage.

[0037] 本发明的外科线形切割缝合器的钉仓内的推钉块的两个侧面为圆柱面,推钉孔的两个侧面为与推钉块的两个圆柱面的侧面相配的圆柱面,钉槽从钉仓壳的端面延伸到安装在钉仓壳的推钉孔内的推钉块的推钉槽处。 [0037] both sides of the linear surgical staples of the present invention, the push blocks within the stapler to staple cartridge side two cylindrical surfaces, pushing the nail holes of mating cylindrical surfaces of two sides of the staple pushing block cylindrical surface , extending from the end surface of the staple slots of the staple cartridge housing mounted to the staple slots of the staple pushing the push block pushes the staple hole of the staple cartridge housing. 由于推钉块和推钉孔的两个侧面为圆柱面,可以采用通用切削刀具方便地加工成具有很高精度的圆柱面,能够保证推钉块在推钉孔内定位正确,不需要在推钉块的两个侧面加工长筋条,也不需要在对应的位置留有钉槽,因此, 这种结构既减少了加工难度,又大大减少了推钉块在推钉孔内移动时的阻力。 Since the two sides of the staple pushing the nail hole and the push block is a cylindrical surface, using a common cutting tool can be easily processed into a cylindrical surface having a very high precision, to ensure that the staple pushing staple pushing block bore positioned correctly, it is unnecessary to push two long sides of the ribs staple processing block, the staple does not need to leave the position corresponding to the groove, and therefore, this arrangement not only reduces the difficulty of processing, but also greatly reduces the resistance when the staple pushing block bore staple pushing movement . 在推钉板依靠斜面推动推钉块将缝合钉从钉仓内推出的前半段过程中,虽然推钉块侧向受力较大,但是在对应的位置没有钉槽,推钉块的圆柱形侧面没有挤压到钉槽,钉槽不会发生弹性变形, 此时推钉块在推钉孔内移动时的阻力较小。 In the nail plate depend on the inclined surface of the cylindrical push the staple pushing the push block will be pushed out from the staple cartridge during the first half, although the staple pushing block side larger force, but not in the position corresponding to the staple slots, the staple pushing block no side grooves pressed into the staple, the staple elastically deformable groove does not occur at this time when the staple pushing small block bore staple pushing resistance to movement. 在推钉板依靠斜面推动推钉块将缝合钉从钉仓内推出的后半段过程中,此时推钉块侧向受力已很小,虽然在对应的位置有钉槽,推钉块的圆柱形侧面挤压钉槽的力很小,钉槽也不会发生明显的弹性变形,此时推钉块在推钉孔内移动时的阻力也较小。 Pushing the nail plate depend on the staple pushing the push block ramp during half of the staples introduced from the staple cartridge, staple pushing block at this time is very small lateral force, although the staple slots, staple pushing block at a position corresponding to the cylindrical side grooves staple pressing force is small, the staple slots not significantly deformed elastically, when the staple pushing block bore when the staple pushing movement resistance is small.

[0038] 与现有的各种外科线形切割缝合器的钉仓相比较,本发明的外科线形切割缝合器的钉仓在使用时更方便、更准确、更省力、更安全,装配检验时更便利,生产成本更低。 [0038] stapler staple cartridge as compared with the conventional variety of surgical linear, linear surgical stapler according to the present invention, the cartridge is more convenient in use, more accurate, and more labor-saving, safer, and more test assembly convenience, lower cost of production.

[0039] 于是可以看出,上述所陈述的目标,包括由前面说明所显示的那些目标被有效地达到了。 [0039] Thus it can be seen, the above stated objectives, including those from the foregoing description of the target displayed is effectively achieved. 这里所述的仅仅是本发明申请的典型的最佳实施形式,可以对上述结构作某些变化也不违背本发明的精神和范围。 Herein are merely exemplary of the preferred embodiment of the application of the present invention, the above-described configuration may be some variations not departing from the spirit and scope of the invention. 本发明不局限或被限止于这里所陈述的具体细节,而应保留对所属领域中等技术人员来说是显而易见的任何改进或改型。 Or limiting, the present invention is not limited to the specific details set forth herein, but should retain any improvements or modifications of ordinary skill in the art medium is obvious.
