Abstract
A disposable ultrasonic surgical handle connectable to an ultrasonic transducer, an ultrasonic waveguide, a removable battery, and an ultrasonic-signal-generator assembly, includes a handle body with a portion defining a battery-holding compartment, the battery-holding compartment having at least two battery contacts, a waveguide attachment dock exposed to the environment and shaped to accept the waveguide therein, a transducer attachment dock exposed to the environment and shaped to place the ultrasonic transducer in coaxial alignment with the waveguide when the waveguide is disposed within the waveguide attachment dock, and an ultrasonic-signal-generator assembly dock exposed to the environment. The ultrasonic-signal-generator assembly dock is shaped to substantially simultaneously selectively removably secure the ultrasonic-signal-generator assembly to the handle body, place an end of the ultrasonic transducer within the transducer attachment dock, and electrically couple the ultrasonic-signal-generator assembly to the at least two battery contacts.
