An apparatus and method for assembly and disassembly of interchangeable surgical acoustic members includes a fixture for securing by a key a handpiece to which a tip and/or extender is attached. A torquing wrench has a tightening head and an untightening head on the same body, wherein the tightening head permits torquing of the tip and/or extender to a predetermined tightening torque in cooperation with a socket having a central bore therethrough so that the wrench and socket 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 and receives the tip and/or extender in a handtightened condition to be torqued to a predetermined limit by the torquing wrench while secured against rotation in the handpiece fixture. A table support structure for supporting a handpiece fixture for an alternative operation is also disclosed. The components are designed for a ready exchange of acoustic tips prior to, during, or after surgery in the sterile field with minimum inconvenience.
