Abstract
Disclosed is an ultrasonic surgical instrument comprising a transducer base plate, first and second piezoelectric elements positioned on opposite faces of the transducer base plate. The transducer base plate is coupled to a waveguide. The waveguide is electrically coupled to the first and second piezoelectric elements by a conductive adhesive. The first and second piezoelectric elements are electrically coupled to an ultrasonic signal generator through an electrode. A thermal conductor conducts thermal energy away from the first and second piezoelectric elements. Also disclosed is a method of fabricating such an ultrasonic surgical instrument.
