Invagination type glue ring lock catch fixed intestines fitting ring

Abstract

The invention relates to a telescopic lock catch fastened intestinal anastomosis ring, belonging to a anastomosis device, in particular to a telescopic lock catch fastened intestinal anastomosis ring of the intestinal operation after the total stomach removal, providing a telescopic lock catch fastened intestinal anastomosis ring without intestinal anastomotic leakage, anastomotic stenosis and foreign body residue at the anastomotic and with few reflux, smooth passing of the holding substance and low medical service cost. The invention comprises an elastic ring, an inner ring and an external ring; wherein, a plurality of an annular inner grooves are arranged at the bottom of the inner ring, a clasp is arranged at the inner side of the inner ring; a plurality of annular outer grooves are arranged at the bottom of the external ring, the barb arranged at the inner side of the bottom of the external ring and the annular clasp forms a lock catch.

Description

technical field [0001] The invention relates to an anastomosis instrument, in particular to a set-in rubber ring lock buckle fixing intestinal anastomosis ring for intestinal operation after total gastrectomy. Background technique [0002] After total gastrectomy, the anastomosis between the intestine and the esophagus must be performed, but after anastomosis with the existing stapler, complications such as postoperative anastomotic leakage, anastomotic stenosis, reflux, and affecting food passage often occur, and Existing staplers are expensive. [0003] 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. C...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to aim at the deficiencies of the existing tubular stapler type staplers and other anastomotic instruments, to provide a postoperative intestinal anastomotic leak, no anastomotic stenosis, less reflux, and smooth passage of contents. Intestinal anastomotic ring with no foreign body residue at the anastomosis and lower medical expenses
