An ultrasonic surgical assembly includes 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 an ultrasonic transducer having a proximal end disposed within the shell and an ultrasonic-movement-producing distal end, 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.
