Sleeve type lock fixation intestine anastomosis ring

Abstract

An embedded latch fixed enteroanastomosis ring relates to an anastomosis device, in particular to an embedded latch fixed enteroanastomosis ring for enteron operation after the full gastric resection. The present invention provides an embedded latch fixed enteroanastomosis ring after the operation with no enteroanastomosis stoma leakage, no narrow anastomotic stoma, less reflux, smooth content flow, no foreign and residual substances in the anastomotic stoma and low medical expense. The present invention comprises an internal ring, an external ring and a flexible ring; the bottom of the internal ring is provided with an annular outward trough; the upper part of the annular outward trough is provided with an annular groove; the lower part of the external ring is provided with an annular inward convex hook; the annular inward convex hook is matched and jointed with the annular outward trough on the bottom of the internal ring; the annular inward convex hook is provided with a annular ditch; the flexible ring is arranged between the annular groove and the annular ditch; the annular inward convex hook on the lower part of the external ring and the annular outward trough on the lower part of the internal ring form the latch connection.

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
