Abstract

The present application belongs to the technical field of operation auxiliary robots, and particularly relates to a remote central motion mechanism based on scissors mechanism, comprising a base assembly, a scissors mechanism assembly and an instrument fixing assembly. The base assembly comprises a base, a driving mechanism, a first rotating shaft and a second rotating shaft; the scissors mechanism assembly comprises a first scissors mechanism connected with a first cam follower and a second scissors mechanism connected with a second cam follower; the instrument fixing assembly comprises an instrument fixing base, a first rotary shaft and a second rotary shaft arranged on the instrument fixing base. The remote central motion mechanism of the present application acts based on the retractable scissors mechanism, so that the whole remote central motion mechanism may be designed to have a smaller volume with a wider motion range, and may effectively avoid the interference problem of the surgical instruments arranged on the instrument fixing base.

Description

technical field [0001] The invention belongs to the technical field of surgical assistant robots, and in particular relates to a distal central motion mechanism based on a scissors mechanism. Background technique [0002] With the widespread popularization and promotion of minimally invasive surgery, surgical assistant robots have played an increasingly important role in minimally invasive surgery, such as the Da Vinci surgical robot system, which assists medical staff to complete operations by controlling the movement of surgical instruments held by them. Operation. In the process of robot-assisted minimally invasive surgery, all surgical instruments must move around the wound. At the same time, due to the requirement of small wounds, the movement space of surgical instruments is limited accordingly. In order to limit the range of movement of surgical instruments to the center of the wound During the movement of surgical instruments, there is a basic fixed point, that is, ...
