Biological balloon dilatation catheter

Abstract

The invention discloses a biological balloon dilatation catheter and relates to the technical field of catheter. The biological balloon dilatation catheter disclosed by the invention comprises a firstcatheter body, a handle, a third catheter body, a fourth catheter body and a first fixed plate, wherein a group of second blocking plates and a third blocking plate are sequentially fixed to an innerwall of the first catheter body from left to right, a fifth catheter body and a fourth blocking plate are sequentially fixed to an inner wall of the fourth catheter body from top to bottom, and one end of the third catheter body penetrates through one surface of the fourth blocking plate and extends into the fourth catheter body. According to the biological balloon dilatation catheter disclosed by the invention, a steel wire is pulled to drive a first supporting rod to slide in an air bag, so that a second fixed plate is driven to rotate, the second fixed plate and a fourth fixed plate are matched, supporting plates are opened, the air bag is supported by the plurality of the supporting plates, and a blocked part can be better opened by the air bag; furthermore, a deformation degree of the air bag is protected to be smaller, and no secondary damage is generated to blood vessels; meanwhile, blood circulation cannot be blocked in a treating process, and safety of patients is protected.

Description

technical field [0001] The invention belongs to the technical field of catheters, in particular to a biological balloon expansion catheter. Background technique [0002] In today's society, the aging population continues to intensify, the incidence of diabetes is also increasing, and the prevalence of cardiovascular and cerebrovascular and peripheral blood vessels is also increasing. In vascular diseases, arterial stenosis will directly endanger the life safety of patients, making Human blood will affect people's normal life because of the blockage, and in severe cases, it will directly cause people to faint or even die. [0003] For arterial blockage, the existing treatment methods are generally divided into three types: conservative drug treatment, surgery, and interventional therapy. Among them, interventional therapy has a better effect and the longest maintenance time. At the same time, interventional therapy is used The instrument used is generally a balloon dilatatio...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a biological balloon dilatation catheter. By pulling the steel wire, the first rod is driven to slide inside the balloon, so that the second fixing plate is rotated, so that the second fixing plate cooperates with the fourth fixing plate, thereby Stretch the support plate, so that several support plates support the airbag, so that the airbag can better open the blocked part, and solve the problem that the existing biological balloon expansion catheter will damage the good blood vessels at both ends of the blocked object
