Abstract: A method and apparatus for periodically interrupting ultrasonic power applied to a ultrasonically vibrating tip to control its amplitude between high and low or zero amplitudes with a selectible duty cycle and repetition rate provides enhanced fragmentation and improves surgical control. The duty cycle may also vary as a function of a remotely sensed parameter such as tissue temperature.

Abstract: An ultrasonic surgical aspirator having an improved irrigation/aspiration manifold and components to facilitate quick connections of the irrigation and aspiration lines to a handpiece. In combination with a handle assembly having an ultrasonic vibrator for vibrating an ultrasonic tip and a nosecone, a nosecone extension defining a rotating joint for connection to the nosecone in an articulating joint for connection to a rigid or flexible flue is provided. The nosecone extension further defines an irrigation cowl having an irrigation port for receiving an irrigation connector for connecting the irrigation fluid to the nosecone extension for passage of irrigation fluid through the nosecone extension and a flue about the surgical tip. An aspiration tubulation connector adapted to securely fit a slot through the nosecone and nosecone extension connects an aspiration port on the tip to the aspiration tube for connection to a pump into a discard area. An alternative manifold assembly includes a nosecone extension adapter defining a rotating joint for connection to the nosecone in a cylindrical portion for connection to an extender sheath, the opposite end of which is connected to a flue adapter defining an articulating joint for connection to a flue. Such an alternative manifold assembly is particularly adapted for use in elongated and curved tips with extenders. The detailed structure of the aspiration tubular connector and the irrigation connector is also shown.
