Abstract

A surgical instrument includes a body, a shaft assembly, an end effector, a clamp actuator, and a blade cooling system. The end effector has a clamp arm and an ultrasonic blade coupled with an ultrasonic transducer. The clamp arm is configured to selectively move from a first actuator position toward a second actuator position thereby directing movement of the clamp arm from the open position toward the closed position, respectively. The cooling system is operable to deliver fluid coolant to the ultrasonic blade to thereby cool the ultrasonic blade while the clamp actuator remains in the first actuator position.
