Embodiment Construction

[0026] The specific embodiment of the present invention is shown in the attached drawings and is composed of a drainage tube 1 and a fixed barb 3; it is characterized in that a lumen container 2 is processed on the inner wall of the drainage tube 1, and a lumen is processed in the lumen container 2 Pavilion 6; each lumen Pavilion 6 is separated by a one-way valve 5, each lumen Pavilion is processed with a marking point 4; outside the drainage tube 1 tube wall processing a fixed barb 3.

[0027] The marking point 4 is made of radiopaque material.

[0028] The drainage tube 1 is filled with radioactive particles 7 in the corresponding lumen 6 according to the position where it is inserted into the lesion. The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited

[0029] Herein, all those skilled in the art are within the technical scope disclosed in the present invention, according to

[0030] The t...

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 drainage tube carrying radioactive particles of the present invention relates to the technical field of medical devices, and is a biliary drainage stent capable of carrying a source of micro-radioactive particles. Background technique [0002] Currently, 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, etc. Since most of these cases have lost the opportunity of surgery when they are diagnosed, the surgical resection rate is 15% to 20%, and palliative shunt bypass surgery is only applicable to 19% of cases. Since the early 1990s, with the development of internal stent technology, ERCP palliative methods have been widely used to treat malignant obstructive jaundice at home and abroad, with satisfactory clinical results, making 70% of the previous...
