Abstract

A system for robotic surgery makes use of an end-effector which has been configured so that any selected one of a group of surgical tools may be selectively connected to such end-effector. The end-effector makes use of a tool-insert locking mechanism which secures a selected one of the surgical tools at not only a respective, predetermined height and angle of orientation, but also at a rotational position relative to an anatomical feature of the patient. The tool-insert locking mechanism may include interchangeable inserts to interconnect multiple tools to the same end-effector. In this way, different robotic operations may be accomplished with less reconfiguration of the end-effector. The end-effector may also include a tool stop which has a sensor associated with a moveable stop mechanism which may be positioned to selectively inhibit tool insertion or end-effector movement.
