Sleeve type intestinal anastomosis ring

Abstract

The invention provides an invaginated intestinal anastomosis ring with simpler structure, shorter operation time, simplified operating procedures, higher safety and reliability and lower medical expenditure, and relates to an anastomosis apparatus. The invaginated intestinal anastomosis ring is provided with an inner ring and an elastic outer ring, wherein the upper part of the inner ring is provided with at least two vertical through channels; the vertical through channels correspondingly divide the upper part of the inner ring into at least two inner ring pieces; the lower parts of the vertical through channels are provided with annular grooves; and the upper part of the outer ring is provided with convex rings matched with the annular grooves of the inner ring. The invaginated intestinal anastomosis ring has a very simple structure, remarkably shortened operation time, more simplified operating procedures, higher safety reliability and lower anastomosis apparatus cost and medical operation cost.

Description

Intestinal anastomotic ring technical field The invention relates to an anastomosis instrument, in particular to a set-in fixed intestinal anastomosis ring for intestinal operation. Background technique Intestinal surgery is a common operation, especially after total gastrectomy, the anastomosis between the intestine and the esophagus must be performed. Complications such as reflux and affecting food passage, and the cost of existing staplers are relatively high. The currently used tubular stapler type stapler (such as the CDH25 stapler produced by Johnson & Johnson in the United States) is to staple together the distal and proximal intestinal canals with double rows of metal nails, and forms a narrow ring without stretching function after healing, thus causing surgery. Complications such as posterior anastomotic leakage, anastomotic stenosis, reflux and affecting food passage. The invention patent application with the publication number CN1036898 provides an elastic c...
