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 clam

Embodiment Construction

[0028] A guide wire / catheter delivery device for vascular intervention surgery will be described in further detail below in conjunction with the embodiments and the drawings.

[0029] See figure 1 with 2 In one embodiment, a guidewire / catheter delivery device 100 for vascular intervention surgery includes a clamping mechanism 10, a propulsion assembly 20 for driving the clamping mechanism to move, and a guiding mechanism 30 for guiding the movement path of the guidewire or catheter.

[0030] See image 3 In one embodiment, the clamping mechanism 10 includes a fixed slide rail type clip 110 and a sliding clip 120 that are arranged oppositely, a first non-slip elastic block 130 fixed on the fixed slide rail type clip 110, and a fixed slide clip 120 The second non-slip elastic block 140, and the clip spring 150 arranged between the fixed slide rail type clip 110 and the sliding clip 120, the first non-slip elastic block 130 and the second non-slip elastic block 140 are arranged opposit...

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...
