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 first and second guide surfaces along the internal passageway, the housing comprising a plurality of slots extending to the proximal end of the housing;
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, the proximal end of the first jaw comprising geared teeth;
a second jaw slidably and pivotally connected to the housing, the first 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 proximal end of the second jaw comprising geared teeth;
a driver engaged with the proximal ends of the first and second jaws, the driver comprising teeth that mesh with the geared teeth of the jaws;
an elongated drive wire selectively connected to the driver for longitudinal movement therewith; and
a tubular connector defining a lumen sized to slidably receive a connection block, the connection block structured to frictionally engage a proximal end of the housing, the connection block defining a bore slidably receiving the drive wire, a distal end of the drive wire defining a distal head that is larger than the bore, the connection block comprising a connection ring having a plurality of tabs;
wherein the housing is structured to block rotation of the first and second jaws when in their retracted positions, and the housing is structured to permit rotation of the first and second jaws when in their extended positions;
wherein the distal head engages the connection block upon proximal retraction of the drive wire and slides the connection block proximally relative to the tubular connector to disengage the connection block from the housing; and
wherein the plurality of slots receives the plurality of tabs.
