Guide wire intervention device for minimally invasive intervention surgical robot

Abstract

The invention belongs to the field of medical equipment, and particularly relates to a guide wire intervention device for a minimally invasive intervention surgical robot. The device comprises a sliding rail, two or more mobile finger assemblies and two or more rotation assemblies, wherein the mobile finger assemblies and the rotation assemblies move along the sliding rail; each mobile finger assembly comprises a mobile finger driving motor, a clamping mechanism and a mobile finger base; each rotation assembly comprises a fixed shell, a rotation disk and a rotation disk motor which drives therotation disk to rotate, each rotation disk is fixedly connected with the clamping mechanism of one of the mobile finger assemblies, and each fixed shell is fixed on the corresponding mobile finger base; a guide wire penetrates through the clamping mechanism and the rotation disk of each mobile finger assembly and intervenes into the blood vessel, and the rotation speeds of the driving motors of the mobile fingers of all the mobile finger assemblies are different. According to the guide wire intervention device, conveying and rotation motion of the guide wire is controlled by the different motors and can be synchronously conducted, and the device more accords with habits of doctors in the actual surgical process.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to a guide wire intervention device for a minimally invasive interventional surgery robot. Background technique [0002] Minimally invasive interventional surgery robots mainly include positioning devices, guide wire interventional devices, image navigation equipment, and monitoring equipment. The guide wire intervention device realizes the delivery, rotation and resistance measurement of the guide wire. In the existing cases, the delivery of the guide wire relies on the rope drive to drag the guide wire clamping finger to move back and forth with the guide wire to realize the delivery of the guide wire; The friction force generated by the two rollers squeezing the guide wire drives the guide wire to move back and forth. In order to realize the rotation of the guide wire, there are usually two ways. One is that the interventional device itself rotates and the ...
