Abstract

A surgical cutting instrument includes movable and stationary jaws at a distal end of an elongate probe formed of an outer tubular member and an inner tubular member rotatable therein, a cam and cam follower at the distal end for translating rotary motion of the inner member to pivotal motion of the movable jaw to cut bodily tissue. The stationary jaw has an opening in the bottom thereof to allow cut bodily tissue to exit to a location external of the surgical cutting instrument, and a suction passage along the inner member terminates at a mouth disposed relative to the cam such that the cam contacts and comminutes cut bodily tissue before the tissue enters the mouth and is aspirated through the suction passage.
