Abstract

The invention belongs to the field of medical equipment, and particularly relates to a guide wire clamping mechanism of a minimally invasive surgery robot. The guide wire clamping mechanism comprisesa clamping motor, a bottom block, a top block, a first connecting rod, a second connecting rod, a third connecting rod and a fourth connecting rod. An output shaft of the clamping motor is hinged to one end of the first connecting rod, the other end of the first connecting rod is hinged to one end of the second connecting rod and one end of the third connecting rod, and the top block is hinged tothe other end of the second connecting rod. The other end of the third connecting rod is hinged to one end of the fourth connecting rod, the other end of the fourth connecting rod is hinged to a fixedhinge support, and a planar six-link mechanism is formed by the first connecting rod, the second connecting rod, the third connecting rod, the fourth connecting rod, the top block and the bottom block. The clamping motor drives the planar six-link mechanism to move, a guide wire penetrates between the bottom block and the top block, and when the top block abuts against the bottom block, the guidewire is clamped. The clamping mechanism is simple in structure and reliable in clamping.

Description

Technical field

[0001] The invention belongs to the technical field of medical equipment, and specifically relates to a guide wire clamping mechanism of a minimally invasive interventional surgical robot. Background technique

[0002] Minimally invasive interventional surgery robots mainly include positioning devices, guide wire intervention devices, image navigation equipment, and monitoring equipment. The guidewire interventional device realizes the delivery, rotation and resistance measurement of the guidewire. A guidewire clamping mechanism is required to hold the guidewire during the guidewire intervention process and deliver the guidewire through the interventional device. The guide wire for interventional surgery is usually clamped by rollers or flat plates due to the small diameter of the guide wire during operation; roller clamping is a pair of rollers close to each other to clamp the guide wire, and the guide wire is in point contact. It is not reliable enough and is e...
