A quick-loading biliary drainage stent for treatment

Abstract

The invention discloses a quick-installation type biliary drainage bracket for treatment, which belongs to the technical field of medical devices, and comprises a quick-installation mechanism. One side of the quick-installation mechanism is covered with a guide wire mechanism. An external support mechanism is fixedly connected, and the inner cavity of the external support mechanism is fixedly connected with an internal support mechanism. The external support mechanism includes an external support frame, and the external support frame is composed of a first memory wire, a second memory wire and an electric heater. Metal wires are twisted and braided, and the inner cavity of the outer support frame is connected with an inner support mechanism through transmission, and one side of the outer support frame is fixedly connected with a weight pad. In the present invention, by setting the inner airbag, the inner airbag can be quickly assembled and positioned through the cooperation of the inner cable and the air valve, and there is no need to wait for the memory metal of the outer support frame to warm up and expand to limit the support before suturing after surgery, thereby significantly shortening the Reduce the operation time, reduce the postoperative risk caused by the long operation time, and improve the safety of the operation.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a quick-installed biliary drainage bracket for treatment. Background technique [0002] According to the structural characteristics of endoscopes, endoscopes can be divided into two types: rigid rigid endoscopes and flexible fiber endoscopes. Classified by disciplines, there are digestive endoscopy, thoracoscopy, laparoscopy, respiratory endoscopy, cystoscopy, pyeloscopy, hysteroscopy, arthroscopy, ventriculoscopy, nasopharyngoscopy, vascular endoscopy and cardiology. Bile duct stenosis is the cicatricial narrowing of the bile duct lumen caused by bile duct injury and recurrent cholangitis or congenital. In endoscopic shell treatment, biliary drainage stents are often used as surgical instruments in endoscopic surgery. Biliary drainage stents are used to slow down the condition of patients with malignant biliary obstruction by placing stents on the biliary tract. [000...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is: in order to solve the problem that the tumor is easy to enter between the memory metal grids, which leads to the need to separate the tumor when the drainage stent is taken out, which easily leads to the rupture of the tumor surface, and the existing biliary drainage stent only uses the material of the memory metal itself Performance support, lack of self-stability, and lack of effective positioning and placement means, waiting for a long time for memory metal recovery, and a quick-installed biliary drainage stent for treatment is proposed
