摘要：
An ultrasonic surgical instrument is provided, including a handpiece, a lever operably coupled to the handpiece and movable between first, second, and third positions, a shaft assembly extending distally from the handpiece, and an ultrasonic waveguide extending through the shaft assembly and defining a fixed jaw member at a distal end portion thereof. An outlet at the distal end of the fixed jaw member provides irrigation of fluid. The waveguide functions as an aspirator well as a transector/dissector of tissue. A movable jaw member is disposed towards a distal end portion of the shaft assembly and is operably coupled to the lever such that movement of the lever between the first, second, and third positions moves the movable jaw member relative to the fixed jaw member between a retracted position, an extended open position, and an extended closed position.
