Patent ID: 8535311

Claim:
A surgical instrument, comprising: an end effector, comprising: a first jaw; a second jaw, wherein said first jaw is movable relative to said second jaw between an open position and a closed position; and at least one electrode; a closure member operably coupled with said first jaw; a firing member movable between a proximal position and a distal position, wherein said firing member comprises: a distal portion positionable within said end effector; and a proximal drive portion; and a handle, comprising: a trigger rotatable between a first position, a second position, and a third position; a cam operably engaged with said trigger, wherein said trigger is configured to orient said cam in a first orientation when said trigger is in said first position and a second orientation when said trigger is in said second position, and wherein said cam comprises: a first cam portion operably engageable with said closure member, wherein the movement of said cam between said first orientation and said second orientation is configured to impart a closing motion to said closure member and move said first jaw between said open position and said closed position; and a second cam portion operably engageable with said proximal drive portion of said firing member, wherein the movement of said trigger between said second position and said third position is configured to impart a firing motion to said firing member and move said firing member from said proximal position to said distal position, and wherein said cam is mounted to said trigger such that said cam is rotated with said trigger, wherein said first cam portion comprises a cam slot, wherein said closure member comprises a cam follower positioned within said cam slot, wherein said proximal drive portion comprises a proximal drive surface and a distal drive surface, and wherein said second cam portion comprises a drive member configured to engage said distal drive surface and move said firing member from said proximal position to said distal position when said trigger is moved from said second position to said third position.
