  • ULTRASONIC HANDPIECE
    Publication number: 20180228507
    Abstract: An ultrasonic handpiece includes a horn and a transducer system. The transducer system is configured to detect a first pressure applied to at least a first portion of the transducer system, transmit a signal associated with the first pressure, and generate ultrasonic vibratory energy. The first pressure is associated with a second pressure applied to the horn.

  • ULTRASONIC INSTRUMENT USING LANGEVIN TYPE TRANSDUCERS TO CREATE TRANSVERSE MOTION
    Publication number: 20130006266
    Abstract: A Langevin transducer horn uses split electroding or selective electroding of transducer elements and phase relationships of the voltages applied thereto to determine the relative longitudinal and flexural/transverse motion induced in the tip of the horn.
