Measuring device for guidewire friction force of interventional surgery robot

Abstract

The invention discloses a guide wire friction force measuring device for an interventional operation robot. The guide wire friction force measuring device comprises a square tube connecting piece, a miniature linear guide rail, a sliding block, a right-angle connecting piece, a miniature tension and pressure sensor, and an electromagnet. The miniature linear guide rail is mounted on the upper surface of the bottom of the square tube connecting piece. The sliding block is mounted on the miniature linear guide rail. The right-angle connecting piece is fixedly mounted above the sliding block. Twoends, in the axial direction of the miniature linear guide rail, of the miniature tension and pressure sensor are force measuring ends; one force measuring end is fixed to the right-angle connectingpiece; and the other force measuring end is fixed to the square pipe connecting piece. The electromagnet is installed on the right-angle connecting piece and is used for attracting a guide wire clamping piece. According to the invention, a problem that the guide wire and the force measuring device are inconvenient to install is solved by means of indirect force measuring and a sterile environmentof the guide wire is guaranteed; the stress change condition of the axial friction force of the guide wire is judged by measuring the push-pull force of the miniature tension and pressure sensor, so that the doctor is reminded of operation in time, and the safety of a patient is protected.

Description

technical field [0001] The present invention relates to the technical field of minimally invasive vascular interventional surgery, in particular, it relates to the control technology for the feedback of the robot from the end to the guide wire in the interventional operation, and more specifically, it relates to a device for measuring the frictional force of the guide wire of the interventional surgery robot. Background technique [0002] Nearly 30 million people die from cardiovascular and cerebrovascular diseases in the world every year, accounting for about 30% of all disease mortality. Among them, the number of people suffering from cardiovascular and cerebrovascular diseases in my country is nearly 300 million. Cardiovascular and cerebrovascular diseases have become one of the three major causes of human death, seriously affecting national health and people's normal life. [0003] Cardiovascular and cerebrovascular minimally invasive interventional therapy is the main t...
