Patent ID: 8876857

Claim:
A surgical tool comprising: an elongate shaft having a proximal end and a distal end; a tool body disposed at the distal end of the shaft; a jaw movable relative to the tool body between a clamped configuration and an open configuration; a first actuation mechanism coupled with the jaw and operable to vary the position of the jaw relative to the tool body between the clamped configuration and the open configuration; and a second actuation mechanism coupled with the jaw, the second actuation mechanism having a first configuration in which the jaw is held in the clamped configuration and a second configuration in which the position of the jaw relative to the tool body is unconstrained by the second actuation mechanism; wherein the jaw opens and closes on a distal side of a jaw pivot, wherein the first actuation mechanism applies force to the jaw at a proximal side of the jaw pivot to vary position of the jaw, and wherein the second actuation mechanism applies force to the jaw at the proximal side of the jaw pivot to hold the jaw in the clamped configuration.
