Optimization and design of remote center motion mechanism of Minimally Invasive Surgical robotics

摘要

Minimally Invasive Surgery (MIS) has many advantages and is achieved mainly by Remote Center Motion. In this paper, a new RCM mechanism which is triangle is proposed, this mechanism is simple and high stiffness. Optimization incorporating the requirements for MIS are performed to find the optimal link lengths of the manipulator. The results show that for the serial triangle2-link manipulator used to guide the surgical tool, the optimization link angles are (74°, 51°). Three-dimensional model design is achieved.
