Abstract
An ultrasound surgical apparatus and associated methods of use enabling relatively pain-free wound debridement is provided. The apparatus is constructed from a tip mechanically coupled to a shaft. The shaft is mechanical coupled to an ultrasound transducer driven by a generator. The ultrasound tip possesses at least one radial surface, a cavity, or some other form of a hollowed out area, within at least one of the radial surfaces, and a cutting member at the opening of the cavity. A method of debriding a wound and/or tissue with the apparatus can be practiced by delivering ultrasonic energy released from the various surfaces of the vibrating tip to the wound and/or tissue prior to and/or while portions of the tip are scrapped across the wound and/or tissue.
