Decoupling mechanism and steel wire transmission device for minimally invasive medical instrument

Abstract

The invention discloses a decoupling mechanism and a steel wire transmission device for a minimally invasive medical instrument, which comprise a decoupling mechanism bracket, a decoupling mechanism fixed shaft guide wheel, a decoupling mechanism fixed pin shaft, a decoupling mechanism movable shaft guide wheel, a decoupling mechanism movable pin shaft, a decoupling mechanism guide strip, a decoupling mechanism rack, a decoupling mechanism gear and a decoupling mechanism gear shaft. The decoupling mechanism fixed shaft guide wheel and the decoupling mechanism guide bar are connected with the decoupling mechanism support through the decoupling mechanism fixed pin shaft, and the decoupling mechanism movable shaft guide wheel and the decoupling mechanism rack are connected with the decoupling mechanism support through the decoupling mechanism movable pin shaft. The decoupling mechanism guide strip is connected with the decoupling mechanism rack in a sliding mode, the decoupling mechanism gear is connected with the decoupling mechanism support through the decoupling mechanism gear shaft, and the decoupling mechanism gear is connected with the decoupling mechanism rack in a meshed mode. The device is simple in structure, convenient to operate and easy to maintain.

Description

technical field [0001] The invention relates to a medical device, in particular to a decoupling mechanism and a wire transmission device for a minimally invasive medical device. Background technique [0002] In December 2018, the paper "Research on Key Technologies of Minimally Invasive Surgical Robotic End-Effective Devices" written by Jin Xingze was published in the journal "Jilin University Doctoral Dissertations". Section 2.2.4 of the second chapter of this paper discloses a decoupling mechanism. The decoupling mechanism is composed of twelve gears and three pulleys, the structure is complicated, the operation is inconvenient, and the maintenance is not easy. At the same time, an independent wire guide shaft is used in the transmission mechanism in the prior art. When the guide wire shaft is fixed with multiple steel wires, it is difficult to adjust the tightness of each steel wire independently, which brings great harm to minimally invasive surgery. hidden dangers. ...
