Guide wire/catheter delivery device for vascular interventional operation

Abstract

A guide wire / catheter delivery device for vascular interventional operation comprises a clamping mechanism, a propelling assembly and a guiding mechanism, wherein the propelling assembly is used for driving the clamping mechanism to move; and the guiding mechanism is used for guiding a guide wire or catheter movement path. When a sliding clamp of the clamping mechanism is close to a fixed slidingtrack type clamp, a first anti-sliding elastic block and a second anti-sliding elastic block tightly presses a guide wire or a catheter so as to clamp the guide wire or the catheter; the propelling assembly comprises a boss synchronous belt, a synchronous belt pulley moving mechanism and a synchronous belt pulley tensioning mechanism; the boss synchronous belt and the synchronous belt pulley moving mechanism drive the clamping mechanism to move; and the synchronous belt pulley tensioning mechanism is used for tensioning a synchronous belt pulley so as to adjust the tightness of the boss synchronous belt. The guide wire / catheter delivery device for vascular interventional operation is small in size and high in delivery precision.

Description

Technical field [0001] The invention belongs to the technical field of auxiliary equipment for vascular interventional surgery, and particularly relates to a guidewire / catheter delivery device for vascular interventional surgery. Background technique [0002] Cardiovascular disease is currently one of the diseases with the highest mortality rate in the world. The traditional treatment methods for cardiovascular diseases include medical treatment and surgical treatment, but medical treatment has many problems such as poor therapeutic effect, high cost, and incurable cure; surgical treatment is performed by incising tissue outside the body. A method of treatment, but this method has problems such as greater pain and longer hospital recovery time. With the development of medical technology, vascular interventional surgery has become an effective method for the treatment of cardiovascular diseases. [0003] Traditional vascular interventional surgery requires doctors to guide and mon...

Problems solved by technology

[0006] At present, the guide wire / catheter delivery devices of most existing vascular interventional robots can be mainly divided into two types: friction-driven and sliding platform. Among them, the friction-driven vascular interventional robot has a simple driving method, a small overall volume of the mechanism, and a compact structure. However, there is a problem that the friction wheel clamping force is too small to easily cause the guide wire or catheter to slip during the intervention process, and the clamping force is too large to easily cause damage to the guide wire or catheter, which makes the transmission accuracy of the overall mechanism poor; the sliding platform type vascular interventional robot uses The screw drive solves the problems of poor transmission accuracy of the current friction drive type, but at the same time, there are problems such as the overall size of the robot is large, the robot is noisy, and the propulsion motor needs to be rotated frequently, etc., and the operation efficiency is low.
