Novel stent drainage tube applied to pancreaticoenterostomy and method thereof

Abstract

The invention provides a novel stent drainage tube applied to pancreaticoenterostomy and a method thereof. The novel stent drainage tube comprises a pancreatic duct supporting drainage tube and a measuring device; an illuminating lamp, a first clamping and fixing device assembly, a second clamping and fixing device assembly and a pancreatic duct diameter measuring tube are arranged in the measuring device. After the pancreatic duct diameter measuring tube is clamped by the first clamping and fixing device assembly and the second clamping and fixing device assembly, the size of the pancreatic duct is measured and the contact between hands and a patient is reduced; and better observation is realized, a pancreatic duct supporting drainage tube with a proper specification is selected accordingto the measured size; barbs are arranged on the surface of the pancreatic duct supporting drainage tube and side holes are formed; after the pancreas duct supporting drainage tube is inserted into the pancreas duct, the barbs are clamped and fixed in the pancreas duct, the situation of loosening is avoided; the operation process is very simple, the pancreas section does not make contact with theinterior of the jejunum, so that the novel support drainage tube applied to pancreaticoenterostomy has the effects that operation is easy, and the occurrence rate of pancreas fistula is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of surgical medical instruments, in particular to a novel stent drainage tube applied to pancreaticojejunostomy and a method thereof. Background technique [0002] Pancreaticojejunostomy is the anastomosis of the remaining pancreas with the jejunum and is a necessary step in the reconstruction of the digestive tract after pancreaticoduodenectomy. By the 1990s, the operative mortality rate of pancreatoduodenectomy was reduced to less than 5%, so it has become the standard operation for the treatment of periampullary tumors, pancreatic head tumors, and a small number of other benign pancreatic diseases. It is worth mentioning that although the mortality rate during pancreatoduodenectomy has been decreasing, the incidence of complications has remained high, the most important of which is postoperative pancreatic fistula. The incidence of pancreatic fistula after pancreaticoduodenectomy is 20% to 40%. Once pan...
