Improved pancreas intestine bundling and embedding inosculating device

Abstract

The invention provides an improved pancreas intestine bundling and embedding inosculating device relating to a pancreas intestine inosculating appliance. The improved pancreas intestine bundling and embedding inosculating device is more simple, accurate, stable and safe to operate, greatly saves the operation time and can remarkably reduce complicating diseases and operation cost. The improved pancreas intestine bundling and embedding inosculating device is provided with a pancreatic tissue bundling and annular binding fixed belt and an intestine overturn fixed ring; the upper surface of the pancreatic tissue bundling and annular binding fixed belt is provided with a convex hook distributed along the longitudinal direction of the fixed belt; the upper part of the convex hook is an inclined surface; the longitudinal direction of the convex hook is vertical to the longitudinal direction of the pancreatic tissue bundling and annular binding fixed belt; the lower surface of the pancreatictissue bundling and annular binding fixed belt is provided with at least one row of specula distributed along the longitudinal direction of the fixed belt; the intestine overturn fixed ring is an elastic fixed ring; and the inside edge at the bottom of the intestine overturn fixed ring is provided with a convex ring which is inosculated with the pancreatic tissue bundling and annular binding fixed belt.

Description

technical field [0001] The invention relates to a pancreaticojejunal anastomosis device, in particular to an improved pancreaticojejunal binding sleeve anastomosis device. Background technique [0002] At present, the complications of pancreaticojejunostomy leakage after surgical pancreaticoduodenectomy are as high as 20%, and the mortality rate is 20% to 50%. Pancreaticojejunostomy leakage is the most common and serious complication of pancreatic surgery, and it is also Unsolved problems in medicine today. [0003] The invention patent with the notification number CN1823688 provides a pancreaticojejunal stapler, which is in the shape of an elliptical cylinder. The pancreaticojejunal stapler is made of polyglycolic acid. There are protruding teeth, and a plurality of through holes are provided on the side wall of the elliptical cylinder, and a contraction structure that makes the inner diameter of the elliptic cylinder smaller is also provided on the elliptical cylinder.
