Staple cartridge, staple cartridge assembly and anastomosis device

Abstract

This disclosure details a staple cartridge, a staple cartridge assembly, and an anastomosis device, all related to the medical device technology field. A feed groove of the staple cartridge described in this disclosure is designed to extend in the first predetermined direction. Multiple staple slot groups are distributed on both sides of the feed groove along the slot width direction. The number of staple slot groups on each side of the feed groove differs, resulting in different anastomosis stability and widths on both sides of the feed groove along the slot width direction.This can specifically enhance the stability of the anastomosis on the side with a greater number of staple slot groups and can meet the differentiated anastomotic requirements of the tissue-retaining and tissue-discharging ends. Not only does this improve the anastomosis effect on the tissue-retaining end, but it also reduces the amount of bleeding at the tissue-retaining end. Simultaneously, it can also address the issues of anastomosis overuse and the waste of anastomotic staples on the tissue-discharging end. Figure for summary: 1.
