Abstract

The invention provides a pancreas and intestine anastomat. The pancreas and intestine anastomat comprises a slender rod, an anastomosis cap, a through hole and a pancreatic juice hole, wherein the anastomosis cap is fixed on the slender rod, the slender rod is of a hollow structure with the through hole, and the pancreatic juice hole is formed in one end of the slender rod. The invention provides a novel pancreas-intestine / stomach anastomosis method and apparatus. The method and the apparatus can change a conventional method of suturing pancreas and stomach and intestine with sutures, the pancreas and intestine anastomat has the functions of reconstructing a passage for pancreatic juice to enter a digestive tract, preventing the pancreatic juice from leaking and conveniently connecting and anastomosing the stomach and intestines and a pancreatic juice stump, no sutures are needed, and the anastomosis is convenient and firm.

Description

technical field [0001] The invention relates to the field of medical instruments, further relates to surgical instruments, in particular to a pancreaticojejunal stapler. Background technique [0002] Surgical operations began to explore the resection and anastomosis techniques after pancreatic and duodenal lesions in the early 20th century. Up to now, there is no convenient, fast and safe anastomotic device in pancreatic surgery. The conventional method needs to cover the pancreatic remnant with sutures. end and jejunum or stomach, so that pancreatic juice can enter the digestive tract, the specific suturing steps are as follows figure 1 As shown, from step A to step D, gradually suture the stump of pancreas and jejunum or stomach together. [0003] The anastomotic method of embedding the stump of the pancreas with sutures requires good suturing techniques. The operation is difficult and high-strength. Dense sutures will cause poor blood supply to the stump, affecting heali...
