In this paper, we present a new robotic uterine positioner for total laparoscopic hysterectomy. The robot is designed to actively position the patient's uterus during surgery, a lengthy and tedious task that is traditionally performed by a human assistant. Safety is simply the most important concern when developing robots for surgical purposes; we address this concern in the design of our robot from...
Remote center of motion (RCM) mechanisms are widely used in surgical robots to mechanically constrain the position of a certain point in the operation space. Examples of well-known RCM mechanisms include parallelogram mechanisms, spherical linkages, circular guiding arcs, etc. In this paper, a reinforced circular-guided RCM mechanism is presented. In the mechanism, a closed-looped circular-guiding...
