Abstract

An ultrasonic surgical assembly includes a reusable cordless ultrasonic transducer and a disposable handle body that defines a battery-holding compartment therewithin, having an ultrasonic surgical waveguide, and operable to removably couple the transducer to the waveguide, the transducer being removably couplable to the handle body.

Claims

1. An ultrasonic surgical assembly comprising:

a removable shell housing a cordless ultrasonic transducer and having an outer surface with at least one electrically communicating contact for supplying power to the transducer; and

a handle body;

defining a battery-holding compartment therein;

having an ultrasonic surgical waveguide; and

operable to removably couple the transducer of the shell to the waveguide, the shell being removably couplable to the handle body and the transducer being operable to dynamically produce a resonant wave along the waveguide coupled thereto to thereby produce movement at a portion of the waveguide sufficient to at least one of cut and cauterize human tissue.

2. The assembly according to claim 1, further comprising:

a battery disposed within the battery-holding compartment.

3. The assembly according to claim 2, wherein the battery is one of integral with the handle body and removable from the handle body.

4. The assembly according to claim 1, wherein the handle body rotatably couples the waveguide and the transducer thereto such that a rotation of the waveguide causes a corresponding rotation of the transducer.

5. The assembly according to claim 1, wherein the waveguide is rotatably coupled to the handle body and is interchangeably removable from the handle body.

6. The assembly according to claim 5, wherein the waveguide is disposable.

7. The assembly according to claim 1, wherein the resonant wave is a sine wave.

8. An ultrasonic surgical assembly, comprising:

an ultrasonic surgical waveguide;

a removable shell housing a cordless ultrasonic transducer and having an outer surface with at least one electrically communicating contact for supplying power to the transducer;

a battery electrically coupled to the at least one electrically communicating contact and operable to supply power thereto; and

a handle body operable to removably couple the waveguide and the transducer of the shell thereto, the shell being separable from the handle body and the transducer being operable to dynamically produce a resonant wave along the waveguide coupled thereto to thereby produce movement at a portion of the waveguide sufficient to at least one of cut and cauterize human tissue, the battery being one of integral with the handle body and removable from the handle body.

9. The assembly according to claim 8, wherein:

the handle body rotatably couples the waveguide and the transducer thereto such that a rotation of the waveguide causes a corresponding rotation of the transducer; and

the waveguide is rotatably coupled to the handle body and is interchangeably removable from the handle body.

10. The assembly according to claim 8, wherein the resonant wave is a sine wave.

11. An ultrasonic surgical assembly, comprising:

an ultrasonic waveguide having a proximal couple part;

a removable shell housing substantially all of a cordless ultrasonic transducer, the ultrasonic transducer having a distal couple part operable to removably couple to the proximal couple part, the shell having an outer surface with at least one electrically communicating contact for supplying power to the transducer;

a battery electrically coupled to the at least one electrically communicating contact and operable to supply power thereto; and

a handle body defining a battery-holding compartment shaped to removably receive the battery therein and having;

a transducer dock exposed to the environment and shaped to interchangeably hold the shell thereat;

a waveguide attachment dock shaped to align and attach the distal and proximal couple parts together and thereby hold the waveguide and the transducer at the handle body when the waveguide is docked in the attachment dock; and

a driving-wave generation circuit at the handle body and electrically contacting the battery and the transducer, the generation circuit operable to dynamically produce a resonant wave along the waveguide to thereby cause ultrasonic movement in the waveguide through the transducer when the transducer is coupled to the waveguide.

12. The assembly according to claim 11, wherein the distal and proximal couple parts include a threaded hole and a threaded rod.

13. The assembly according to claim 11, wherein the waveguide is longitudinally fixed to the handle body.

14. The assembly according to claim 11, wherein the waveguide is releasably connected to the handle body.

15. The assembly according to claim 11, wherein the battery is disposable.

16. The assembly according to claim 11, wherein the battery is reusable, and further comprising a compartment door movably attached to the handle body at the battery-holding compartment, the door having:

an open position permitting entry and removal of the battery respectively into and out from the battery-holding compartment; and

a closed position aseptically sealing the battery-holding compartment from the environment.

17. The assembly according to claim 11, wherein:

the transducer dock is operable to rotatably connect the waveguide therein; and

the attachment dock and the transducer dock are shaped and disposed to directly physically couple the waveguide and the transducer and cause a corresponding rotation of the transducer with respect to the handle body when the waveguide rotates.

18. The assembly according to claim 17, wherein a maximum amount of rotation of the transducer with respect to the handle body is limited.

19. The assembly according to claim 11, wherein the handle body has a handgrip and the battery-holding compartment is within the handgrip.

20. The assembly according to claim 11, further comprising a device identifier communicatively coupled to the handle body and operable to communicate at least one piece of information about at least one of the waveguide, the transducer, the battery, the generation circuit, and the handle body.

21. The assembly according to claim 20, wherein the at least one piece of information is at least one of a waveguide identifier, an information list of previous waveguide use, a transducer identifier, an information list of previous transducer use, a battery identifier, an information list of previous battery use, a battery status, a handle identifier, and an information list of previous handle use.

22. The assembly according to claim 21, wherein the device identifier is operable to communicate with the battery when the battery is in the battery-holding compartment.

23. The assembly according to claim 11, wherein the handle body has a battery ejector at the battery-holding compartment operable to cause at least a portion of a battery within the battery-holding compartment to eject therefrom.

24. The assembly according to claim 11, wherein the resonant wave is a sine wave.
