1. A method for assembling an ultrasonic surgical device, the method comprising:

  • providing a proximal end of an ultrasonic waveguide at an ultrasonic surgical handle body;

    removably coupling to the ultrasonic surgical handle body a cordless ultrasonic-movement-generator assembly having a shell containing therein an ultrasonic-driving-wave-signal generating circuit;

    mechanically coupling a cordless ultrasonic transducer rotationally freely and substantially longitudinally fixedly to the ultrasonic surgical handle body to place an ultrasonic-movement-producing distal end of the ultrasonic transducer opposite and adjacent the proximal end of the ultrasonic waveguide; and

    rotating the waveguide and the ultrasonic transducer with respect to one another to removably fixedly couple the waveguide to the ultrasonic-movement-producing distal end of the ultrasonic transducer and to electrically couple the ultrasonic-driving-wave-signal generating circuit of the shell to the ultrasonic surgical handle body, wherein the ultrasonic transducer is operable to dynamically produce a resonant wave along the ultrasonic waveguide when the ultrasonic transducer is excited by the ultrasonic-driving-wave-signal generating circuit.
