    摘要： A surgical apparatus comprises a body, a shaft assembly, a rotation input assembly, and an end effector. The shaft assembly defines a longitudinal axis and a first fluid passageway. The rotation input assembly is operable to rotate the shaft assembly about the longitudinal axis. The rotation input assembly defines a second fluid passageway. The second fluid passageway is in fluid communication with the first fluid passageway. The end effector is located at a distal end of the shaft assembly. The end effector comprises an ultrasonic blade. The end effector is in fluid communication with the first fluid passageway such that the end effector is configured to receive fluid communicated through the first and second fluid passageways.

    摘要： A surgical apparatus comprises a body, a shaft assembly, an end effector, and a blade cooling system. The shaft assembly couples the end effector and the body together. The shaft assembly comprises an acoustic waveguide and defines an interior space. The acoustic waveguide is configured to couple with an ultrasonic transducer. The end effector comprises a clamp arm and an ultrasonic blade in acoustic communication with the ultrasonic transducer. The clamp arm is configured to pivot toward and away from the ultrasonic blade. The shaft assembly comprises an inner tube configured to longitudinally translate to thereby pivot the clamp arm toward and away from the ultrasonic blade. The cooling system is operable to deliver liquid coolant a distal portion of the shaft. A trigger of the body is operable to rotate to thereby translate the ultrasonic blade into and out of the interior space of the shaft assembly to thereby cool the ultrasonic blade.
