Pipeline support capable of carrying drug particles

Abstract

The invention relates to the technical field of medical equipment, in particular to a pipeline support capable of carrying therapeutic drug particles, which can be arranged through a minimally invasive method, is mainly used for supporting a bile duct and a pancreiatic duct stenosis caused by disease, and has a local treatment function. The pipeline support consists of a drainage tube and a drug carrying tube. The drug carrying tube is arranged in the cavity of the drainage tube, and the drug carrying tube is closely attached to one side inner wall of the drainage tube. When the pipeline support is in use, the drug particles can be placed into and fixed in the drug carrying tube according to a treatment scheme. A filling material can be selectively adopted according to the treatment requirement to seal the cavity part between two or more adjacent drug particles on two ends and inside the drug carrying tube. The pipeline support is simple in structure and can be minimally-invasively placed into a human body through an endoscope, is convenient to use and have the local treatment function and a drainage function.

Description

technical field [0001] The invention relates to the technical field of medical devices, and is a pipeline stent capable of carrying therapeutic drug particles, which is placed through a minimally invasive intervention method, is mainly used to support bile duct and pancreatic duct stenosis caused by lesions, and has a local treatment function. Background technique [0002] Diseases of the biliary and pancreatic system are common clinical diseases, which can be divided into two categories: benign lesions and malignant lesions. Lesions often affect the patency of the pancreatic duct and bile duct, resulting in stricture or obstruction. For pipeline stenosis or obstruction, at present, a pipeline stent with a drainage function is mainly inserted through a medical endoscope to prop up the stenosis. Biomaterials used to manufacture pipeline stents mainly include polymer materials and metal materials. The polymer pipeline stent commonly used in clinical practice consists of a dr...

Problems solved by technology

However, the above-mentioned stents can only carry tiny sources of radioactive particles, and the diameter of the effective drainage cavity is relatively small, the texture of the stent is relatively hard, and the patency time is short, which limits clinical application.

[0012] In summary, there is currently a lack of a well-designed polymer scaffold that can carry sufficient drug particles, not only radioactive particles, but also non-radioactive drug particles.
