Spiral contractible tube type gastrointestinal anastomat crew abutting seat fixing device

Abstract

The invention belongs to the technical field of medical instruments and discloses a spiral contractible tube type gastrointestinal an astomat nail abutting seat fixing device. A nail abutting seat is implanted into an intestinal tube; a fixing device is fixed to the end of the intestinal tube through a purse string stitching mode. The fixing device is provided with a purse string suture, and the purse string suture is provided with a tail end and a head end; the tail end of the purse string suture penetrates into a buckle; the head end is connected with a needle rod; the needle rod is connected with a needle head; and the needle head is clamped in the buckle. A spiral memory material is used for replacing a common suture, the nail abutting seat is firmly fixed in a reverse buckling mode, knotting is not needed, and fixing can be easily, conveniently and firmly completed even if operation is conducted under a microscope. The fixing device is provided with the purse string suture, the purse string suture is provided with the tail end and the head end, and tightening is achieved; the tail end of the purse string suture penetrates into the buckle, the buckle is used for assisting the purse string suture to tighten, and so that the intestinal tube and the nail abutting seat are fixed.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a screw-shrinkable tube-type gastrointestinal stapler anvil seat fixing device. Background technique [0002] At present, the gastrointestinal stapler is the first stapler in the world. It has been used for gastrointestinal anastomosis for nearly a century. It was not until 1978 that the tubular stapler was widely used in gastrointestinal surgery. It is generally divided into one-time or multiple-use staplers, imported or domestic staplers. It is a device used in medicine to replace traditional manual suturing. Due to the development of modern technology and the improvement of production technology, the clinically used stapler is reliable in quality, easy to use, tight and suitable, especially its fast suturing, easy operation and There are few side effects and surgical complications, and it also enables tumor resection that was unresectable in the past.

AI Technical Summary

Problems solved by technology

Although the existing technology is simple and easy to implement, it is difficult to complete or the fixation is not reliable in deep tissues (such as high esophagus or low rectum) and thoraco-laparoscopic.

[0003] Through the above analysis, the problems and defects of the existing technology are: the existing technology is difficult to complete or not fixed firmly under deep tissue and thoraco-laparoscopic, and the thread knots are prone to fall off, resulting in tissue retraction, resulting in difficulties in surgical operation
