Abstract
A surgical manipulator (10) can manipulate a medical tool (12) with one or more degrees of freedom. In preferred embodiments, the manipulator (10) is a parallel mechanism including a plurality of arms (21, 22) pivotally supporting a medical tool (12), with the orientation of the medical tool (12) being adjusted by varying the position of joints (23, 24) mounted on the arms (21, 22). The motions of the joints (23, 24) can be controlled such that the tool (12) is pivoted about a virtual pivot point located within the body wall of a patient (30). The manipulator (10) can enhance the dexterity of an operator and enable the operator to perform medical procedures more easily than by hand.
