ABSTRACT:
A surgical instrument includes a motor, a dissecting tool coupled to the motor for rotation about an axis of the motor, the motor further including a base at one end thereof. The motor is further provided with an elongate member extending from the base and parallel to the motor axis. A foot member extends laterally from a terminal end of the elongate member for protecting selected portions of tissue from exposure to the cutting action of the dissecting tool. The surgical instrument is further provided with indexing means to permit selective rotation of the elongate member relative to base from one of a plurality of angular positions to another of the plurality of angular positions, and to secure the elongate member in a selected angular position.
