Guide wire and catheter push device of blood vessel interventional operation

Abstract

The invention provides a guide wire and catheter push device of a blood vessel interventional operation and aims to push a guide wire and a catheter. The device comprises a complete set of solving schemes of a guide wire push device, a guide wire twisting and rotating device and an airbag bracket catheter push device, wherein the guide wire push device consists of a driving motor, a bevel gear group, rollers and an electronic guide wire clamping mechanism; the guide wire twisting and rotating device consists of a driving motor, a gear rack moving pair, a sliding track and sliding block group and an electronic guide wire clamping mechanism; and the airbag bracket catheter push device consists of a driving motor, a bevel gear group, rollers and a manual catheter clamping mechanism. The guidewire and catheter push device provided by the invention effectively integrates push actions of the guide wire and the catheter and is applicable to a mainstream guide wire and RX rapid exchange balloon catheter in the market, actions of artificial wire delivery can be simulated, the purpose that operation is completed by using interventional equipment in one operation process can be achieved, theworking intensity of an operation subject can be alleviated, and the time that the operation subject suffers from radiation can be shortened.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a guide wire catheter propelling device for vascular interventional surgery. Background technique [0002] Vascular disease is the number one major disease of mankind entering the 21st century. The use of minimally invasive interventional surgery can successfully dredge the blood vessels, release the stent, and relieve the pain of the patient. In traditional surgery, under the guidance of X-ray images, operations are performed in the lumen of blood vessels with the help of guide wires and catheters. During the whole process, the doctor needs to wear a heavy lead suit to work under X-rays. At the same time, the guide wire and catheter are rotated, pushed and pulled, and bent completely by hand. The lead suit is very heavy, and the guide wire and catheter are manually operated for a long time. It makes the medical staff more prone to fatigue, and the weak movement of the ...

AI Technical Summary

Problems solved by technology

American Corpath and Hansen robots can operate catheters under the control of doctors, but their structures are complex and special catheters are required. At the same time, the feeding and rotation of catheters have no feedback, etc., which cannot meet the safety requirements of medical devices.
