Abstract

The present invention relate to the field of medical aids, in order to solve the problem of inadequate drainage of pancreatic juice. A support tube for dilate pancreaticojejunostomy is provided, whichcomprise a support tube, a main duct provided with a drainage section, a dilation section and an extension section communicated in sequence, wherein that support tube comprises a support tube, a support tube for dilate pancreaticojejunostomy and a support tube for pancreaticojejunostomy. The outer circumferential diameter of the drainage section is smaller than the outer circumferential diameterof the expansion section, and the drainage section is provided with a plurality of drainage holes. The outer peripheral wall of the dilated segment closely fits the inner peripheral wall of the pancreatic duct. The diameter of the drainage segment is small, and the dilated segment is placed in the main pancreatic duct of the residual pancreas. The pancreatic juice is sealed on one side of the drainage segment. The drainage segment and the drainage hole are used to drain the residual pancreatic juice. At the same time, the dilated segment can effectively avoid pancreatic juice flowing to the pancreatic-intestinal anastomosis and pancreatic fistula.

Description

technical field [0001] The invention relates to the field of medical auxiliary tools, in particular to an expandable pancreaticojejunostomy support tube. Background technique [0002] Pancreaticoduodenectomy is the most commonly used method for addressing tumors of the pancreatic head, the end of the bile duct, and the duodenum. The essence of pancreaticojejunostomy is the anastomosis of the section of the pancreas as a solid organ and the small intestine as a hollow organ. This anastomosis itself is extremely difficult due to the different nature of the two, and the failure rate is high. Postoperative anastomotic leakage is very likely to occur in such operations, which is pancreatic fistula. The reasons for anastomotic leakage are very complicated and there are many factors. Excessive tension and so on after anastomosis. Pancreatic fistula with bleeding and infection will increase the risk of postoperative death. In clinical practice, how to avoid this risk has become ...
