Invagination type glue ring lock catch fixed intestines fitting ring

Abstract

The utility model relates to a fixed intestinal anastomosis ring with a rubber ring lock buckle which fits in, and relates to an anastomosis instrument, in particular to a fixed intestinal anastomotic ring with a rubber ring lock buckle which is inserted in and used for bowel operation after total gastrectomy. Provided is a set-in plastic ring lock-fixed intestinal anastomosis ring with no postoperative intestinal anastomotic leakage, no anastomotic stenosis, less reflux, smooth passage of contents, no foreign matter residue at the anastomosis, and low medical expenses. An elastic ring, an inner ring and an outer ring are provided. The lower part of the inner ring is provided with an annular inward groove. Hook, the barb located on the inner side of the lower part of the outer ring and the ring hook located on the inner side of the inner ring form a lock.

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...

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
