  • Patent number: 10426508
    Abstract: A disposable ultrasonic surgical handle includes a disposable handle body defining a battery-holding compartment shaped to receive a battery therein and operable to couple a proximal end of an ultrasonic waveguide to an ultrasonic transducer therethrough. The body has a transducer dock exposed to the environment and interchangeably housing the transducer and a waveguide attachment dock shaped to align and attach the proximal end of the waveguide to the transducer and hold them at the body when the respectively docked at the transducer and attachment docks. A disposable driving-wave generation circuit in the handle body electrically contacts the battery and the transducer when the battery and the transducer are disposed respectively in the battery-holding compartment and the transducer dock.
