  • Removable adapter for phacoemulsification handpiece having irrigation and aspiration fluid paths
    Patent number: 8454551
    Abstract: Current phacoemulsification handpieces require rigorous cleaning after each procedure because the aspiration and irrigation pathways for fluids are integral to the handpiece. According to the present invention, a removable horn extension and nosecone may be used with a phacoemulsification handpiece to allow for disposable fluid pathways exterior to the handpiece. This will reduce the cleaning time and effort, reduce cross-contamination, and increase the lifespan of the handpiece. Furthermore, the current invention allows different horn extensions to be used to excite different motions at the tip of the handpiece, depending on the preference of the surgeon.

  • ULTRASONIC INSTRUMENT USING LANGEVIN TYPE TRANSDUCERS TO CREATE TRANSVERSE MOTION
    Publication number: 20130006265
    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.
