Pipe-type oblique-angle digestive tract anastomat

Abstract

The invention relates to the field of medical treatment instruments and equipment, and particularly relates to a pipe-type oblique-angle digestive tract anastomat. The pipe-type oblique-angle digestive tract anastomat comprises a nail supporting seat and a nail bin which are provided with oblique surfaces fit mutually; the nail bin is internally provided with suturing nails and an annular tool which are in flush with the oblique surface of the nail bin. According to the pipe-type oblique-angle digestive tract anastomat provided by the invention, the fit surfaces of the nail pushing seat and the nail bin are oblique surfaces, and after the pipe-type oblique-angle digestive tract anastomat is used, scars on the intestinal canal are changed to be oblique, so that each cross section of the intestinal canal is only provided with two scar points rather than a circle of scar, thereby guaranteeing the original elasticity of the intestinal canal and preventing the unsmoothness and the blocking of the intestinal canal. As the suturing surface is an oblique surface, a large enough fit lip can be reserved by the operation instrument design and cutting, and the problem of mutual contradiction of the cutting inner diameter and the lip is solved, and the problems of small lip, poor blood supply and fistula existence are solved.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a tubular oblique digestive tract stapler. Background technique [0002] At present, the intestinal anastomosis uses a tubular digestive tract stapler, and the intestinal tube to be sutured is connected with a set of flat-angled and equal-circle staplers. However, the anastomotic opening of the general tubular digestive tract stapler is flat and equal, and it is difficult to leave a large enough anastomotic lip for surgical instrument cutting, which cannot completely solve the problem of the contradiction between the inner diameter of the cutting and the lip. And the lips are small, the blood supply is poor, and there is a possibility of fistula. After the sutured bowel tube grows well, a circle of inelastic connection scars will be formed on the inner wall of the bowel tube, causing the bowel tube to be narrowed, blocked, or even blocked. It will cause inconvenience to patients...

Problems solved by technology

However, the anastomotic opening of the general tubular digestive tract stapler is flat and equal, and it is difficult to leave a large enough anastomotic lip in the design and cutting of surgical instruments, which cannot completely solve the problem of the contradiction between the inner diameter of the cutting and the lip

And the lips are small, the blood supply is poor, and there is a possibility of fistula. After the sutured bowel tube grows well, a circle of inelastic connection scars will be formed on the inner wall of the bowel tube, causing the bowel tube to be narrowed, blocked, or even blocked. It brings inconvenience to patients, affects the quality of life or brings certain risks
