ABSTRACT:
A surgical instrument actuation system is provided with a double-acting fluid pressure piston pump and a double-acting fluid actuator. An operating member is connected to the pump piston, and a two-position directional valve communicates between the pump and actuator. A valve actuator means is responsive to the pump pressure or to the position of the pump piston or actuator piston. This switches the valve from the first position to the second position so that the system operates to apply a higher actuator force at a lower stroking speed.
