ABSTRACT:
A powered surgical tool includes a battery-operated motor that has an eccentrically mounted drive wheel for engaging a longitudinally movable drive wire that operates to incrementally rotate a ratchet wheel. A work wheel in the form of a cutting blade or a grinding wheel is mounted for rotational movement with the ratchet wheel at the distal end of the surgical tool. In another version, the cutting blade has a periphery of cutting teeth, which are driven directly by the longitudinally movable drive wire. A grinding wheel version discloses two grinding wheels that are incrementally driven in opposite angular directions by a pair of longitudinally movable drive wires.
