Description

Vascular interventional guide wire/catheter delivery device

technical field

The invention belongs to the technical field of auxiliary equipment for vascular intervention, in particular to a guide wire/catheter delivery device for vascular intervention.

Background technique

Cardiovascular disease is one of the diseases with the highest mortality rate in the world. Traditional treatment methods for cardiovascular diseases include medical drug treatment and surgical operation, but medical drug treatment has many problems such as poor treatment effect, high cost and inability to cure; surgical treatment is performed by incising human tissue. It is a method of treatment, but this method has problems such as greater pain for patients and longer recovery time in hospital. With the development of medical technology, vascular interventional surgery has become an effective method for the treatment of cardiovascular diseases.

Traditional vascular interventional surgery requires doctors to send guide wires or catheters into human blood vessels to reach the lesions to treat diseases under the guidance and monitoring of imaging equipment such as digital subtraction angiography, CT, ultrasound and magnetic resonance. , doctors are exposed to X-ray radiation, which can cause bodily harm.

At present, the commonly used vascular interventional surgery is still performed by the operator directly manipulating the guide wire or catheter, which has major drawbacks: 1) The operator wears lead clothing for a long time to work in the environment of X-radiation, and the lead clothing cannot shield all the 2) Due to the long operation time and the manual delivery of the guide wire or catheter, the precision of the operation is poor, which will affect the effect of the operation. The existence of these problems makes it particularly important to assist physicians in the delivery of guidewires or catheters by robots.

In view of the above-mentioned problems, domestic and foreign scientists and scientific research institutions have proposed a variety of guide wire or catheter delivery methods. Wang Tianmiao's team from Beihang University proposed a vascular intervention robot that uses a motor to drive a friction wheel and uses the friction of the friction wheel to push the guide wire or catheter forward. Wang Lei's team from Shenzhen Institute of Advanced Technology, Chinese Academy of Sciences A vascular intervention robot that uses a high-precision lead screw to forward a guide wire or catheter when the catheter is clamped; Corindus has developed the CorPath 200 vascular intervention robot system dedicated to vascular intervention, which uses a pair of friction wheels to achieve The purpose of forward delivery of a guidewire or catheter.

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