Cordless hand-held ultrasonic cautery cutting device and method
First Claim
1. An ultrasonic surgical handle assembly connectable to a cordless ultrasonic transducer, an ultrasonic waveguide, a battery, and a cordless ultrasonic-signal-generator assembly, the handle assembly comprising:
- a removable shell containing therein a driving-wave generation circuit; and
a handle body having;
a power supply portion defining a battery-holding compartment and having at least two battery contacts at the battery-holding compartment; and
an ultrasonic-signal-generator assembly dock exposed to the environment and shaped to substantially simultaneously;
selectively removably secure the shell directly to the handle body;
andelectrically couple the driving-wave generation circuit to the at least two battery contacts, wherein the driving-wave generation circuit is operable to dynamically produce a resonant wave along the waveguide by exciting the ultrasonic transducer when the transducer is coupled to the waveguide.

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.

22. An ultrasonic surgical handle assembly connectable to a cordless ultrasonic transducer, an ultrasonic waveguide, a removable battery, and a cordless ultrasonic-signal-generator assembly, the handle assembly comprising:
-
a removable shell containing therein a driving-wave generation circuit of the ultrasonic-signal-generator assembly; a first handle body portion defining therein a selectively accessible and aseptically sealable battery-holding compartment; configured to aseptically removably hold therein the removable battery; and having an electrical connector; and a second handle body portion connected to the first handle body portion and having an ultrasonic-signal-generator assembly dock exposed to the environment and shaped to substantially simultaneously; selectively removably secure the shell directly to the second handle body portion; and electrically couple the ultrasonic-signal-generator assembly to the removable battery through the electrical connector when the removable battery is disposed in the battery-holding compartment and the shell is disposed in the ultrasonic-signal-generator assembly dock, wherein the ultrasonic-signal-generator assembly is operable to dynamically produce a resonant wave along the waveguide by exciting the ultrasonic transducer when the transducer is coupled to the waveguide. - View Dependent Claims (23)
