Abstract
An ultrasound assisted liquid blade cutting device such as a scalpel that may be used for routine surgical operations is disclosed in this invention. The ultrasound scalpel comprises an ultrasound generator, ultrasound transducer, transducer tip, a cavity on the transducer tip using a liquid spray shaped to form a cutting surface. The spray serves as a carrier medium for the applied ultrasound energy which enhances the features and performance of the scalpel. Ultrasonic energy transmitted from the transducer tip assists the transport of the liquid to a liquid blade formed outside of the cavity. The ultrasound energy focuses and activates the liquid to allow cutting of tissue with the liquid blade. This device may be utilized for cutting through skin and/other soft tissues during surgical operations, thereby enhancing cutting efficacy, decreasing and/or eliminating necrosis formation.
