CAM DRIVER FOR SURGICAL INSTRUMENTS

An end effector assembly includes first and second jaw members movable between an open and closed position to grasp tissue therebetween. First and second proximal flanges extending proximally from the second jaw member and defining a space therebetween, a proximal flange extend proximally from a proximal portion of the first jaw member and define a cam slot. A cam driver operably is coupled to the proximal flange of the first jaw member to define a space between the cam driver and the proximal flange of the first jaw member. A cam bar is disposed within the space defined between the cam driver and the proximal flange of the first jaw member. The cam bar includes a cam pin configured to move within a cam slot of the cam driver to move the first jaw member relative to the second jaw member between the open position and the closed position.
