Abstract

A disposable ultrasonic surgical handle connectable to an ultrasonic waveguide, a battery, and an ultrasonic-movement-generator assembly includes 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 an electrical couple. The second handle body portion has a waveguide attachment dock exposed to the environment and an ultrasonic-movement-generator assembly dock exposed to the environment and shaped to connect the ultrasonic waveguide in the waveguide attachment dock to the ultrasonic-movement-generator assembly through the second handle body portion. The electrical couple is operable to connect a battery within the battery-holding compartment to the ultrasonic-movement-generator-assembly when the ultrasonic-movement-generator assembly is docked at the ultrasonic-movement-generator assembly dock.

Claims

1. 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.

2. The handle assembly according to claim 1, wherein the ultrasonic-movement-generator assembly dock is one of a rail, a dovetail, a T-slot, and an undercut slot.

3. The handle assembly according to claim 1, wherein the ultrasonic-movement-generator assembly is an ultrasonic transducer-and-generator assembly.

4. The handle assembly according to claim 1, wherein the electrical couple comprises conductive power leads disposed in the battery-holding compartment and positioned to electrically contact the battery.

5. The handle assembly according to claim 1, wherein:

the second handle body portion further comprises a waveguide attachment dock; and

at least one of the waveguide attachment dock and the ultrasonic-movement-generator assembly dock rotatably couples at least one of the ultrasonic-movement-generator assembly and the waveguide to the second handle body portion.

6. The handle assembly according to claim 1, wherein:

a waveguide attachment dock is rotatably attached to the second handle body portion and is operable to rotatably connect the ultrasonic waveguide to the second handle body portion; and

the ultrasonic-movement-generator assembly dock is shaped to rotatably connect the ultrasonic waveguide in the waveguide attachment dock to the ultrasonic-movement-generator assembly through the second handle body portion to correspondingly rotate at least one component of the ultrasonic-movement-generator assembly with respect to the second handle body portion with rotation of the waveguide.

7. The handle assembly according to claim 1, further comprising a compartment door movably attached to the first handle body portion and having:

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

a closed position aseptically sealing the compartment from the environment.

8. The handle assembly according to claim 1, wherein the first handle body portion is a handgrip.

9. The handle assembly according to claim 8, wherein the battery-holding compartment is disposed in a lower portion of the handgrip.

10. The handle assembly according to claim 1, further comprising a memory for storing a handle use history.

11. The handle assembly according to claim 1, further comprising a device identifier communicatively coupled to the battery-holding compartment and operable to communicate at least one piece of information about at least one of the handle, the waveguide, the battery, and the ultrasonic-movement-generator assembly.

12. The handle assembly according to claim 11, wherein the at least one piece of information is at least one of a handle identifier, an information list of previous use, and a waveguide identifier.

13. The handle assembly according to claim 11, further comprising a removable battery assembly, the device identifier being operable to communicate with the battery assembly and to transfer information therebetween.

14. The handle assembly according to claim 1, wherein the first handle body portion further comprises a battery ejector operable to cause at least a portion of the battery to eject from the battery-holding compartment.

15. The handle assembly according to claim 1, wherein the first and second handle body portions are integral.

16. The handle assembly according to claim 1, wherein the electrical couple further comprises conductive power leads in the compartment positioned to electrically contact the battery when the battery is in the compartment.

17. The handle assembly according to claim 1, wherein the ultrasonic-movement-generator assembly comprises:

a transducer having an output couple shaped to connect to the ultrasonic waveguide and being communicatively coupled to the driving-wave generation circuit to create ultrasonic movement at the output couple to produce the resonant wave along the waveguide when attached thereto.

18. The handle assembly according to claim 17, wherein the driving-wave generation circuit comprises at least one of:

a control circuit;

a drive circuit; and

a matching circuit.

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