Cordless hand-held ultrasonic cautery device
First Claim
1. An ultrasonic surgical assembly, comprising:
- a surgical handle including a first handle body portion defining an aseptically sealable battery-holding compartment and a second handle body portion connected to the first handle body portion;
a waveguide supported by and extending distally from the second handle body portion;
a cordless ultrasonic generator supported by the second handle body portion, the cordless ultrasonic generator including a driving-wave generation circuit and a shell housing the driving-wave generation circuit;
a cordless ultrasonic transducer supported by the second handle body portion, the cordless ultrasonic transducer coupled to the driving-wave generation circuit and having an output couple connected to the waveguide; and
a battery, wherein the first handle body portion is configured to removably hold the battery within the aseptically sealable battery-holding compartment, and wherein the surgical handle is configured to electrically connect the battery with the cordless ultrasonic generator when the battery is disposed within the battery-holding compartment.

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. The circuit generates an output waveform sufficient to cause ultrasonic movement along the waveguide by exciting the transducer when the transducer is coupled to the waveguide.
