Abstract

The invention relates to a fixable pancreas duct built-in tube with holes. The pancreas duct comprises a pancreas duct built-in tube, the pancreas duct built-in tube is made of semitransparent silicagel, the total length of the pancreas duct built-in tube is 100-150 mm, the diameter of the pancreas duct built-in tube is 1.8-2.2 mm, drainage holes are evenly formed in the pancreas duct built-in tube from left to right along the tube wall, and fixing lugs are arranged on the pancreas. The pancreatic duct drainage tube has the advantages that the pancreatic duct drainage tube is simple in structure and convenient to use, outflow of pancreatic juice can be increased to a greater extent by the aid of the pancreatic duct drainage hole, and outflow efficiency of the pancreatic juice is improved;and the tube wall can be better fixed by the fixing lugs on the pancreatic duct built-in tube, so that the built-in tube is prevented from slipping, and a better drainage effect is achieved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a fixable pancreatic duct built-in tube with holes. Background technique [0002] In recent years, with the continuous improvement of medical level, pancreatic surgery has been greatly developed, and a large number of pancreatic operations have been carried out. The pancreas is a digestive organ with endocrine and exocrine functions. It is located at a key position in the digestive tract. Pancreatic surgery usually involves partial pancreas resection and reconstruction of the digestive tract. During the reconstruction process, whether the anastomosis of the pancreatic duct and the digestive tract is unobstructed is crucial. It is the key to the success of pancreatic surgery. [0003] At present, in clinical work, there is no pancreatic duct internal tube specially designed for the anastomosis of pancreatic duct and digestive tract. Most of them are replaced by silico...
