Abstract
A surgical apparatus is provided which includes a handle portion and an elongated body portion extending distally from the handle portion and defining a longitudinal axis. A tool assembly is operatively associated with a distal end portion of the body portion and includes a first jaw assembly having a proximal jaw portion and a distal jaw portion and a second jaw assembly having a proximal jaw portion and a distal jaw portion. The distal and proximal jaw portions of each jaw assembly are pivotably connected to one another and are movable between first and second articulated positions. A jaw actuation mechanism is provided including an actuation member and having first and second cooperating actuating legs. Each leg is operatively connected to a respective distal portion of the first and second jaw assemblies to effectuate simultaneous pivotable movement of the distal jaw portions relative to the proximal jaw portions of the tool assembly. A jaw control mechanism operatively connects the handle portion and the tool assembly and is configured to effect movement of the tool assembly between an open position and a closed position.
