Patent ID: 7799039

Claim:
A hydraulically actuated surgical instrument, the instrument comprising: a handle portion; a shaft having a longitudinal axis, the shaft mechanically coupled to the handle; an end effector mechanically coupled to the shaft along the longitudinal axis, the end effector comprising: a first jaw member extending from the distal end of the shaft in a direction substantially parallel to the longitudinal axis; and a second jaw member pivotable towards the first jaw member; wherein the first jaw member comprises: a surgical fastener, at least a portion of the surgical fastener translatable along a transverse axis towards the second jaw member, wherein the transverse axis is substantially perpendicular to the longitudinal axis; a hydraulic device positioned to be expandable toward the surgical fastener in a direction substantially parallel to the transverse axis to actuate the surgical fastener; a surgical cutting edge extending along the longitudinal axis, at least a portion of the surgical cutting edge translatable towards the second jaw member in a direction substantially perpendicular to the longitudinal axis; and a second hydraulic device positioned to be expandable toward the surgical cutting edge in a direction substantially perpendicular to the longitudinal axis to actuate the surgical cutting edge.
