circular cutting stapler

Abstract

The invention discloses an annular cutting stapler, comprising: a shell, which includes a first through hole communicating with the outside; a nail box base, which is disc-shaped and arranged outside the shell and in front of the first through hole, the The base of the magazine is fixedly connected with the shell, the base of the magazine is fixed with an annular nail bin, the upper part of the magazine is provided with staples, the lower part is provided with a push nail head, and the nail magazine and the base of the magazine are provided with There is a nail pushing disc that can move up and down, and an annular boss that is in contact with the nail pushing head is arranged on the nail pushing disc, and an annular cutter located in the inner circle of the nail bin is also arranged on the said nail pushing disc; Nail seat, which is ring-shaped and arranged above the nail bin, the nail abutment seat and the nail box base are hinged in a scissors manner, and a bias spring is arranged at the hinge, and the hinge of the nail abutment seat and the nail box base is close to The first through hole; a closing component and a firing component. The present invention has the advantages of cutting target diseased tissue at one time, simplifying the cutting process, and facilitating better recovery of patients.

Description

technical field [0001] The invention relates to the field of surgical medical operating instruments. More specifically, the present invention relates to a circular cutter stapler. Background technique [0002] Stapler is a device used in medicine to replace manual suturing. The main working principle is to use titanium nails to separate or anastomose tissues, similar to a stapler. There are many staplers on the market, including tubular staplers and disposable laparoscopic linear cutting staplers. Among them, tubular staplers are suitable for end-to-end or end-to-side anastomosis of the esophagus, stomach, and intestinal tract. Its main steps: 1) Depending on the size of the anastomotic caliber, select the staple seat inside the stapler with appropriate specifications, and place a purse at the incision of the esophagus for backup; 2) Remove the head compartment cover of the stapler, check for missing nails, and then Insert the head into the tissue to be cut and sutured, an...

Problems solved by technology

[0004] During the resection process of the tubular stapler, the anvil should be placed in a suitable position first, and then the stapler body and the anvil should be matched, and the tissue can be sutured by rotating the tail knob. There are too many operating procedures and the operation is complicated.

Disposable laparoscopic linear cutting stapler is easy to operate, but for specific gastric surgery, it needs to be resected many times before the damaged tissue can be resected, that is, too much resected tissue is not conducive to the recovery of human tissue function
