Sleeve type lock fixation intestine anastomosis ring

Abstract

The utility model relates to an anastomosis ring of a fixed intestinal anastomosis ring with a set-in locking buckle, which relates to an anastomosis instrument, in particular to a set-in locking buckle fixed intestinal anastomotic ring which is used for bowel operation after total gastrectomy. Provided is a set-in lock-and-buckle 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. There are an inner ring, an outer ring and an elastic ring. The bottom of the inner ring is provided with an annular outward hook groove, and an annular groove is arranged on the upper part of the annular outward groove; The hook is matched with the ring-shaped outward hook groove at the bottom of the inner ring, the ring-shaped inwardly protruding hook is provided with a ring-shaped groove, the elastic ring is arranged between the ring-shaped groove and the ring-shaped groove, and the ring groove is arranged at the lower part of the outer ring. The ring-shaped inward protruding hook forms a locking connection with the ring-shaped outward hook groove arranged at the lower part of the inner ring.

Description

technical field [0001] The invention relates to an anastomosis instrument, in particular to a sleeve-type locking 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. [000...

AI Technical Summary

Problems solved by technology

[0005] 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 anastomotic port and low medical expenses
