Abstract

The invention discloses an endoscope anastomat anti-skidding nail anvil. The nail anvil is characterized in that the nail anvil comprises a nail anvil plate and an anvil head; the anvil head is located at the head portion of the nail anvil plate and is fixedly connected with the nail anvil plate; a plurality of globular anti-skidding bulges are arranged on the anvil head; an anti-skidding layer isarranged on the surface of the anti-skidding bulges. Compared with the prior art, the nail anvil has the advantages of being easy to operate, low in blood oozing risk, high in sustainable productivity, and low in cost.

Description

Technical field [0001] The invention relates to the field of medical equipment, in particular to an anti-skid nail anvil of an endoscopic stapler. Background technique [0002] At present, minimally invasive surgery occupies an important position in surgical operations. Among them, resection of the lesion is an important part of surgery. The current general method is that the surgical instrument has a long shaft or rod-like structure. With the cooperation of the endoscope, the shaft or rod is inserted into the lesion and the lesion is removed. [0003] As a kind of surgical instrument, the laparoscopic stapler is a device used in medicine to replace manual suture; the working principle of the stapler is to clamp the stapler on the lesion site, perform excision, and at the same time use the titanium nail to remove the lesion. To perform separation or anastomosis, similar to a stapler. [0004] However, the head of the surface wall of the nail anvil of the laparoscopic stapler in the...
