Abstract: An improved ultrasonic surgical apparatus includes an ultrasonic handpiece. An ultrasonic fragmenting tool is mountable within the handpiece, the tool having a vibratable tip adapted for ultrasonically fragmenting tissue at a surgical site of a patient. A transducer is mounted within the handpiece and coupled to a connector body. The connector body is coupled to the tip for transmitting ultrasonic waves to the tip from the transducer, the tip and the connector body being constructed of titanium or its alloys. An aspirating system is connected to the handpiece for aspirating fluid and tissue fragmented by the tip from the surgical site. An irrigation system is connected to said handpiece for supplying irrigation fluid to the surgical site for suspending fragmented tissue by the tip. Preferred embodiments include operational frequencies of about 36 kHz.
