Anastomat for surgical department

Abstract

The invention relates to an anastomat for surgical department. The anastomat comprises a casing, a center rod, a push pipe and a nail pushing sheet, wherein the head part of the push pipe is fixedly connected with the bottom surface of the nail pushing sheet, the top of the casing is provided with a nail cabin, suture nails are contained in the nail cabin, the center rod passes through the push pipe and can slide along the push pipe, the center rod extends out of the casing and is in an integral structure, and a nail butting seat is connected with the center rod through a D-shaped fixing hole. The anastomat has the advantages that the structure is simple, the positioning is accurate, the striking stability is high, and the anastomat cutting effect of the anastomat can be ensured; the assembly is convenient, and the use is safe and reliable.

Description

technical field The invention relates to a surgical stapler. Background technique As a common tool in surgical operations, anorectal stapler is widely used to anastomose human tissues, especially the distal rectum, and is suitable for suspension of rectal mucosal prolapse or internal hemorrhoid prolapse in the anal canal. The anorectal stapler can reduce the suturing time of the tissue, improve the suture strength, reduce the difficulty of the operation, effectively protect the suture of the tubular organ tissue, improve the quality of the operation, and greatly improve the healing effect of the suture. Existing medical and surgical staplers can refer to Figure 1, which generally include a housing, a central rod, a pusher tube, and a nail pusher. , staples are housed in the staple bin. The central rod is inserted into the push tube and can slide along the push tube. The central rod protrudes out of the casing, and the head is equipped with a nail abutment seat, an...

AI Technical Summary

Problems solved by technology

Since the end of the central rod is a stepped structure, this will cause a large loss, and during the assembly process of the central rod, due to multiple positioning, there will be cumulative positioning errors, which will easily make the positioning of the anvil and the positioning shaft inaccurate, resulting in The misalignment of the anvil and the upper staple hole of the staple cartridge affects the formation of the staple
