Patent ID: 7018354

Claim:
An adapter for use with an ultrasonic vibrator having an ultrasonic probe thereon, the probe having a proximal end coupled to the ultrasonic vibrator and a distal end, comprising; a handpiece assembly to fit over and locate with respect to the ultrasonic vibrator, the handpiece assembly having a seal to seal with respect to the ultrasonic vibrator and probe to define a first fluid chamber adjacent the proximal end of the ultrasonic probe between the handpiece assembly and an ultrasonic vibrator, the handpiece assembly having an aspiration conduit coupled thereto for fluid communication with the first chamber and adapted for connection to an aspiration unit, the handpiece assembly also having a depressurization opening in fluid communication with the first chamber for controllably venting the first chamber; an evacuation tube coupled to the handpiece assembly and extending over the ultrasonic probe therein, including the distal end of the ultrasonic probe therein, the evacuation tube being adapted to define a fluid passageway between the evacuation tube and a probe therein, which fluid passageway is in fluid communication with the first chamber; the space between the end of the probe and the end of the evacuation tube defining a second chamber, the evacuation tube having at least one opening in the distal end thereof in fluid communication with the second chamber.
