摘要:
An apparatus comprises a body, a shaft assembly, an end effector, and a wetting member. The shaft assembly extends distally from the body. The end effector is located at a distal end of the shaft assembly. The end effector comprises an ultrasonic blade that is configured to vibrate at an ultrasonic frequency. The wetting member is selectively movable between a first position and a second position. The wetting member is configured to be spaced away from the ultrasonic blade in the first position. The wetting member is configured to contact the ultrasonic blade in the second position and thereby apply a cooling fluid to the ultrasonic blade.
