Patent ID: 8771293

Claim:
A medical device for engaging tissue, the medical device comprising: a housing defining an internal passageway and a longitudinal axis extending between proximal and distal ends of the housing, the housing defining first and second guide surfaces along the internal passageway; a first jaw slidably and pivotally connected to the housing, the first jaw having proximal and distal ends, the first jaw slidably received within the internal passageway for longitudinal movement along the first guide surface between an extended position and a retracted position; a second jaw slidably and pivotally connected to the housing, the second jaw having proximal and distal ends, the second jaw slidably received within the internal passageway for longitudinal movement along the second guide surface between an extended position and a retracted position; the housing structured to block rotation of the first and second jaws when in their retracted positions, the housing structured to permit rotation of the first and second jaws when in their extended positions; and a driver engaged with the proximal ends of the first and second jaws, the proximal ends of the first and second jaws including geared teeth, and wherein the driver includes corresponding teeth that mesh with the geared teeth of the jaws, longitudinal movement of the driver moving the first and second jaws longitudinally along the first and second guide surfaces between their retracted and extended positions, longitudinal movement of the driver rotating the first and second jaws relative to the housing when the first and second jaws are in their extended positions.
