1. An ultrasonic surgical assembly, comprising:

  • an ultrasonic waveguide having a proximal end for receiving ultrasonic movement thereat;

    an ultrasonic-movement-generator assembly having;

    a shell;

    an ultrasonic-driving-wave-signal generating circuit housed within the shell; and

    a cordless ultrasonic transducer having a proximal end disposed within the shell and an ultrasonic-movement-producing distal end that when excited by the ultrasonic-driving-wave-signal generating circuit, dynamically produces a resonant wave along the ultrasonic waveguide; and

    a handle body having;

    a waveguide attachment dock operable to accept the waveguide therein;

    an assembly dock shaped to removably secure at least a portion of the ultrasonic-movement-generator assembly thereat, the assembly dock operable;

    to selectively removably secure at least the shell thereat; and

    to position the ultrasonic-movement-producing distal end of the ultrasonic transducer co-axially opposite the proximal end of the ultrasonic waveguide when the ultrasonic waveguide is disposed within the waveguide attachment dock.
