摘要

The apparatus includes a body assembly, an acoustic waveguide, an ultrasonic blade, a liquid distribution feature, and a control module. The liquid dispensing feature is positioned on a circle with respect to the body assembly. The liquid distribution feature is positioned adjacent to the ultrasonic blade. The liquid distribution feature is configured to transfer the flow of cooling liquid to the ultrasonic blades. The control module is operable to adjust fluid flow through the liquid distribution feature.
