Abstract:
1. 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 a jaw guide surface, a first link guide surface and a second link guide surface, each of the guide surfaces extending longitudinally between proximal and distal ends of their respective guide surfaces; 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 jaw guide surface; 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 jaw guide surface; a first link elongated in the longitudinal direction between first and second ends of the first link, the first end pivotally attached to the first jaw, the second end slidably and pivotally attached to the housing for longitudinal movement along the first link guide surface; a second link elongated in the longitudinal direction between first and second ends of the second link, the first end pivotally attached to the second jaw, the second end slidably and pivotally attached to the housing for longitudinal movement along the second link guide surface; and a driver operatively connected to the first and second jaws, longitudinal movement of the driver moving the first and second jaws longitudinally along the jaw guide surface and moving the second ends of the first and second links along the first and second link guide surfaces, longitudinal movement of the driver rotating the first and second jaws relative to the housing when the second ends of the first and second links reach the distal ends of the first and second link guide surfaces.
