Abstract
Abstract The present invention relates to surgical devices. A surgical instrument in accordance with the present invention includes a transducer assembly adapted to vibrate at an ultrasonic frequency. An end effector is adapted to receive ultrasonic vibration from the transducer assembly and to propagate the ultrasonic vibration from a first end to a second end. The end effector is rotatable with respect to the handpiece assembly while the transducer assembly vibrates at the ultrasonic frequency. A method of applying ultrasonic energy to tissue of a patient is also provided. The method includes the steps of providing a handpiece assembly carrying an acoustic assembly having a transducer assembly and an end effector, and energizing the transducer to cause the end effector to vibrate. The method further includes the steps of rotating the end effector with respect to the handpiece assembly while the transducer assembly is vibrating, and contacting the tissue of the patient with the end effector.
