Nail bin nail outlet arrangement structure of endoscope anastomat

Abstract

The invention discloses a nail bin nail outlet arrangement structure of an endoscope anastomat. The structure comprises a nail bin, the far end of the nail bin serves as an initial position, and a plurality of nail outlet sets are sequentially arranged from the initial position. Each nail outlet set comprises two transverse nail outlets close to one side of the initial position in the width direction of the nail bin and four vertical nail outlets away from one side of the initial position in the length direction of the nail bin. In each nail outlet set, every two vertical nail outlets are paired, and each pair of vertical nail outlets is arranged in the width direction of the two ends, in the length direction, of each transverse nail outlet. By the adoption of the design scheme, when an operation is conducted, tissue firstly makes contact with four rows of vertical anastomosis nails, two transverse anastomosis nails cannot be affected by sliding and squeezing of the tissue to generatetearing force, inward recycling force is generated, and the inward recycling force under the action of the anastomosis nails counteracts most of the generated outward reverse force, the risk that thetissue is torn during the operation is reduced, and the operation safety is greatly improved.

Description

technical field [0001] The invention relates to a stapler, in particular to an arrangement structure of nail outlet holes of a staple magazine of a laparoscopic stapler. Background technique [0002] In the process of surgical anastomosis, tight suturing and prevention of leakage are the most important criteria for evaluating the performance of the stapler. A good anastomotic effect can not only reduce the risk during the operation, but also play a great role in the healing of the postoperative wound. , to achieve tight sutures and prevent leakage, in addition to staples, anvils and other components that play a key role, the arrangement of staple holes in the stapler magazine also plays a vital role in the anastomosis effect . [0003] At present, most of the staple cartridge outlet holes on the market are arranged in a vertical pattern. This arrangement is the most common for staplers, and it is also a staple cartridge outlet hole arrangement that achieves a good suture ef...

Problems solved by technology

[0004] Purpose of the invention: The purpose of the present invention is to solve the problem that most of the existing stapler magazine outlet nail holes are arranged in a vertical pattern, which leads to tearing of unsutured tissues, resulting in bleeding, which will lead to serious problems during surgery. After the end, the distal end of the cut has been torn but not sutured, resulting in bleeding and bleeding problems
