Abstract
The system and method includes a manipulator for manipulating a surgical instrument relative to a patient's body and, a position sensor for sensing the position of the surgical instrument relative to the patient's body. The manipulator can be manually or computer actuated and can have brakes to limit movement. In a preferred embodiment, orthogonal only motion between members of the manipulator is provided. The position sensor includes beacons connected to the patient and manipulator or surgical instrument and, a three dimensional beacon sensor adapted to sense the location and position of the beacons. Redundant joint sensors on the manipulator may also be provided. The system and method uses a computer to actively interact with the surgeon and can use various different input and output devices and modes.
