Abstract

A disposable ultrasonic surgical handle includes a disposable handle body that has a first handle body portion defining a handgrip and a second handle body portion connected to the first handle body portion, where the second handle body portion has a waveguide attachment dock exposed to the environment and having a first couple operable to connect an ultrasonic waveguide thereto and an aseptically sealable powered-ultrasonic-motion-generator assembly dock shaped to connect the ultrasonic waveguide in the attachment dock to an assembly within the assembly dock through the second handle body portion. The disposable ultrasonic surgical handle also includes a disposable compartment door movably connected to the second handle body portion to selectively expose the assembly dock to the environment, where the handle has an open position exposing the assembly dock to the environment and permitting entry and removal of the powered-ultrasonic-motion-generator assembly respectively into and from the assembly dock and a closed position aseptically sealing the assembly dock from the environment.

Claims

1. An ultrasonic surgical handle for receiving a powered-ultrasonic-motion-generation assembly therein and coupling an ultrasonic waveguide thereto, the handle comprising:

a handle body having;

a first handle body portion defining a handgrip;

a second handle body portion connected to the first handle body portion and having;

a waveguide attachment dock exposed to the environment and having a first couple operable to connect the waveguide thereto; and

an aseptically sealable powered-ultrasonic-motion-generator assembly dock shaped to connect the waveguide in the attachment dock to the powered-ultrasonic-motion-generator assembly disposed within the assembly dock through the second handle body portion, wherein the powered-ultrasonic-motion-generator assembly comprises;

a driving-wave generation circuit generating an output waveform;

a cordless ultrasonic transducer operable to connect to the waveguide in the attachment dock and to dynamically produce a resonant wave along the waveguide when supplied with the output waveform to thereby ultrasonically move the waveguide; and

a self-contained power source electrically powering the driving-wave generation circuit; and

a compartment door movably connected to the second handle body portion to selectively expose the assembly dock to the environment and having;

an open position exposing the assembly dock to the environment and permitting entry and removal of the powered-ultrasonic-motion-generator assembly respectively into and from the assembly dock; and

a closed position aseptically sealing the assembly dock from the environment.

2. The ultrasonic surgical handle according to claim 1, wherein:

the attachment dock has a waveguide axis;

the assembly dock has a transducer axis; and

the attachment dock and the assembly dock are shaped to coaxially align the transducer axis with the waveguide axis.

3. The ultrasonic surgical handle according to claim 1, wherein the handle body is disposable.

4. The ultrasonic surgical handle according to claim 1, wherein at least one of the door and the second handle body portion has a transparent portion for viewing a display disposed within the second handle body portion from outside the second handle body portion.

5. The ultrasonic surgical handle according to claim 1, wherein the attachment dock is operable to releasably physically couple the waveguide to the second handle body portion.

6. The ultrasonic surgical handle according to claim 1, wherein the attachment dock is rotatably coupled to the second handle body portion and is shaped to rotatably couple the waveguide thereto.

7. The ultrasonic surgical handle according to claim 6, wherein:

the attachment dock is rotatably attached to the second handle body portion;

the first couple is operable to rotatably connect the ultrasonic waveguide to the second handle body portion; and

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

8. The ultrasonic surgical handle according to claim 1, further comprising a memory for storing a handle use history.

9. The ultrasonic surgical handle according to claim 1, further comprising a device identifier communicatively coupled to the assembly dock and operable to communicate at least one piece of information about the handle body.

10. The ultrasonic surgical handle according to claim 9, wherein the at least one piece of information is at least one of a handle identifier and an information list of previous use.

11. The ultrasonic surgical handle according to claim 9, 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.

12. The ultrasonic surgical handle according to claim 9, wherein the device identifier is operable to communicate with the powered-ultrasonic-motion-generator assembly.

13. The ultrasonic surgical handle according to claim 1, wherein the second handle body portion further comprises an assembly ejector operable to cause at least a portion of the powered-ultrasonic-motion-generator assembly to eject from the assembly dock.

14. The ultrasonic surgical handle according to claim 1, wherein the first and second handle body portions are integral.

15. The ultrasonic surgical handle according to claim 1, wherein the driving-wave generation circuit comprises at least one of:

a control circuit;

a drive circuit; and

a matching circuit.

16. The ultrasonic surgical handle according to claim 1, further comprising a display operable to indicate at least one of:

a power state;

a number of handle uses;

a number of waveguide uses;

a number of battery uses;

a battery condition;

a waveguide identifier;

a battery identifier; and

a handle identifier.

17. The ultrasonic surgical handle according to claim 1, wherein the resonant wave is a sine wave.
