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 [0001] The invention relates to a surgical stapler. Background technique [0002] 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. [0003] Existing medical and surgical staplers can refer to figure 1 Generally, it includes a housing, a center rod, a pusher tube and a nail pusher, the head of the pusher tube and the bottom surface of the nail pusher are fixed together, the top of the nail pusher is provided with a staple cartridge, and the staple cartridge is equipped with staple...
