摘要： An apparatus and method for assembly and disassembly of interchangeable surgical acoustic members includes a fixture (50) for securing by a key a handpiece to which a tip and/or extender is attached. A torquing wrench (70) has a tightening head (73) and an untightening head (74) on the same body (71) wherein the tightening head (73) permits torquing of the tip and/or extender to a predetermined tightening torque in cooperation with a socket (92, 93) having a central bore (92a, 93a) therethrough so that the wrench (70) and socket (92, 93) may be slid over an axially elongated combination and used at a point intermediate along the length thereof. In use, the handpiece is secured in the handpiece fixture (50) and receives the tip and/or extender in handtightened condition to be torqued to a predetermined limit by the torquing wrench (70) while secured against rotation in the handpiece fixture (50). A table support structure (102) for supporting a handpiece fixture for an alternative operation is also disclosed.

摘要： An improved ultrasonic surgical handpiece (10) includes an angled connecting body (72) between the transducer (70) and operative tip (74), with the connecting body being bent at a location between the node and antinode at its respective ends and with a second nodal plane support in the transducer section. The vibrating assembly (14) is impedance matched to the frequency of a handpiece employing a straight connecting body of substantially equal length and dimension whereby straight and angulated handpieces may be interchangeably used in an ultrasonic surgical system employing a common drive and common operative tips. In a preferred embodiment, the ultrasonic tranducer has a nodal plane midway between its ends and is supported at this nodal plane.

摘要： A method and apparatus for periodically interrupting ultrasonic power applied to a ultrasonically vibrating tip (11) to control its amplitude between high and low or zero amplitudes with a selectable 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.

摘要： 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.
