Cordless hand-held ultrasonic cautery cutting device

A disposable ultrasonic surgical handle assembly connectable to an ultrasonic waveguide, a battery, and a cordless ultrasonic-movement-generator assembly, the handle assembly comprising:

• a first handle body portion defining therein an aseptically sealable battery-holding compartment shaped to receive the battery therein;
• a second handle body portion connected to the first handle body portion and having
• an ultrasonic-movement-generator assembly dock exposed to the environment and shaped to connect the ultrasonic waveguide to the ultrasonic-movement-generator assembly through the second handle body portion, whereby the ultrasonic-movement-generator assembly is operable to dynamically produce a resonant wave along the waveguide to thereby ultrasonically move the waveguide when connected thereto;
• a removable shell containing therein a driving-wave generation circuit of the ultrasonic-movement-generator assembly and being shaped to dock at the ultrasonic-movement-generator assembly dock;
• and
• an electrical couple operable to connect the battery within the battery-holding compartment to the ultrasonic-movement-generator assembly when the shell is docked at the ultrasonic-movement-generator assembly dock.
