直线型缝切器的钉仓组件Cartridge Assembly for Linear Cutter

技术领域technical field

本发明涉及一种直线型缝切器的钉仓组件，属于医疗器械技术领域。The invention relates to a staple cartridge assembly of a linear seam cutter, which belongs to the technical field of medical instruments.

背景技术Background technique

直线型缝切器被广泛用于外科手术中用于伤口缝合、内部组织缝合与切割，典型的直线型缝切器如美国专利US5129570所揭示，具有缝合与切割两个功能，在进行伤口缝合的同时，将多余的组织切除。该类直线型缝切器一般包括上、下两个钳夹，以及用于闭合上、下钳夹的闭合把手，相对设置在上、下钳夹前端的钉砧和钉仓，设于钉仓内并可同时相对所述钉仓移动推钉杆和切刀，以及用于驱动所述推钉杆和切刀移动的推钮。所述钉仓内排列设置有推钉片和缝合钉，所述推钉杆依次按顺序推动推钉片并将缝合钉推向钉砧进行缝合，所述切刀将位于钉仓和钉砧之间的组织切断。Linear sewing cutters are widely used in surgical operations for wound suturing, internal tissue suturing and cutting. Typical linear sewing cutters, as disclosed in U.S. Patent No. 5,129,570, have two functions of suturing and cutting. At the same time, excess tissue is removed. This type of linear seam cutter generally includes upper and lower jaws, and a closing handle for closing the upper and lower jaws. The nail pusher rod and cutter can be moved relative to the staple cartridge at the same time, and the push button for driving the nail pusher rod and cutter to move. Nail pushers and staples are arranged in the staple cartridge, and the pusher rod sequentially pushes the staple pushers and the staples to the anvil for suturing, and the cutter will be positioned between the staple cartridge and the staple anvil. Intersection of tissue.

另外，在做高位食道癌切除缝合的手术中，有一种“T形缝合术”正在被医生所采取和接受。所谓的“T形缝合术”是指：医生首先用一个直线型缝切器在高位食道上切开一条直线缝合线；再把两条对折的缝合线拉成一条缝合线；然后把两条食道断端再另使用一个直线型缝切器进行相对垂直的缝合。经过多次的试验发现，这种“T形缝合术”可以很好地扩大了缝合口的直径，很好的解决了缝合口狭窄这一高位食道缝合经常发生的事故。但是“T形缝合术”也存在一些隐患，那就是在T型缝合的第一个切口处把两条缝合线拉成一条直线时，其两条缝合线的交点处是一个非常薄弱的地方，容易发生撕裂和缝合强度不够的风险。In addition, in the operation of high esophageal cancer resection and suture, there is a kind of "T-shaped suture" that is being adopted and accepted by doctors. The so-called "T-shaped suture" means: the doctor first cuts a straight suture line on the high esophagus with a linear suture cutter; then pulls the two folded suture lines into one suture line; The broken end is then sutured relatively vertically using a linear seam cutter. After many tests, it was found that this "T-shaped suture" can well expand the diameter of the suture opening, and it can well solve the frequent accident of high esophagus suture, which is narrow suture opening. However, there are also some hidden dangers in the "T-shaped suture", that is, when the two sutures are pulled into a straight line at the first incision of the T-shaped suture, the intersection of the two sutures is a very weak place. Risk of tearing and insufficient suture strength.
