Abstract

The invention discloses a biliary tract internal drainage tube carrying radioactive particles, which relates to the technical field of medical equipment and is a biliary tract internal drainage bracket capable of bearing a micro radioactive particle source. The biliary tract internal drainage tube comprises a drainage tube and a fixing barb, and is characterized in that: an organ cavity container is arranged on the inner wall of the drainage tube; organ cavity chambers are arranged in the organ cavity container. Each organ cavity chamber is separated by a one-way valve; and a marking point is arranged on each organ cavity chamber and made from a radiopaque material. An antiskid fixing barb is arranged outside the tube wall of the drainage tube; and radioactive particles which can be changed anytime are put in corresponding organ cavity chambers according to the position of the drainage tube inserted into the focus. The biliary tract internal drainage tube disclosed by the invention has the advantages of novel structure, low cost, safety, reliability, obvious curative effect and the like, and is simple to process, convenient to use and easy to operate, thereby being a novel biliary tract internal drainage tube carrying radioactive particles integrating economy and practicability.

Description

technical field [0001] The biliary internal drainage tube carrying radioactive particles of the present invention relates to the technical field of medical devices, and is a biliary internal drainage stent capable of carrying miniature radioactive particle sources. Background technique [0002] At present, malignant obstructive jaundice includes a group of malignant tumors that cause bile duct obstruction: hilar liver cancer, cholangiocarcinoma, pancreatic cancer, ampullary cancer, and hilar lymph node metastasis, compression or invasion of the bile duct. Since most of these cases have lost the chance of surgery when they are diagnosed, the surgical resection rate is 15% to 20%, and palliative shunt bypass is only applicable to 19% of the cases. Since the early 1990s, with the development of internal stent technology, ERCP has been widely used as a palliative method to treat malignant obstructive jaundice at home and abroad, and the clinical effect is satisfactory, so that 7...
