Problems solved by technology

There is no connection between the staples, the structural strength is poor, and the space utilization rate is low
When the titanium nail structure is used to deal with thicker tissues, it is easy to suture laxly due to uneven tissue thickness, which leads to bleeding or even suture failure

Abstract

The invention discloses a circular anastomosis ring. The anastomosis ring comprises an anastomosis ring body, the anastomosis ring body is sequentially divided into a suturing nail, a lower rubber ring and an upper rubber ring from bottom to top, a plurality of elastic sheets are arranged between the suturing nail and the lower rubber ring, the suturing nail comprises a supporting ring, a plurality of long nails are arranged at the top end of the supporting ring, and the long nails are evenly distributed around the circle center of the supporting ring. The adaptability of the suturing nail tothe uneven thickness of sutured tissue is improved, suturing safety is guaranteed, the problem that titanium nails are left in a human body and stimulated by foreign matter is solved, residues are reduced, healing is promoted, and medical cost is reduced.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a circular anastomotic ring. Background technique [0002] The stapler is a device used in medicine to replace manual suturing. Its working principle is the same as that of a stapler, that is, it fires and implants two rows of interlaced staples into the tissue to perform double-row cross-stitching on the tissue, and the suture is tight. Prevent leaks. According to the scope of application, it can be divided into: linear stapler, circular stapler, linear cutting stapler, purse string stapler and endoscopic stapler, etc. The existing staples of the existing disposable circular or anorectal stapler are titanium staples, and one suture requires multiple staples to participate. There is no connection between the staples, the structural strength is poor, and the space utilization rate is low. When the titanium nail structure is used to deal with thicker tissues, it is e...
