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.

Claims

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.

2. The ultrasonic surgical assembly according to claim 1, wherein the second handle body portion further includes a waveguide attachment dock operable to removably connect the waveguide to the second handle body portion.

3. The ultrasonic surgical assembly according to claim 1, wherein the cordless ultrasonic generator and the cordless ultrasonic transducer form an ultrasonic-movement-generation assembly, and wherein the second handle body portion further includes an ultrasonic-movement-generation assembly dock configured to removably secure the ultrasonic-movement-generation assembly to the second handle body portion.

4. The ultrasonic surgical assembly according to claim 3, wherein, with the ultrasonic-movement-generation assembly secured to the ultrasonic-movement-generation assembly dock, the output couple is positioned to connect to the waveguide.

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

a control circuit;

a drive circuit;

or a matching circuit.

6. The ultrasonic surgical assembly according to claim 1, further comprising a movable compartment door connected to the first handle body portion and having:

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

a closed position aseptically sealing the battery-holding compartment.

7. The ultrasonic surgical assembly according to claim 1, wherein the first handle body portion forms a handgrip of the surgical handle.

8. The ultrasonic surgical assembly according to claim 1, wherein the battery includes a power source and a power-source controller, the power-source controller operable to maintain one of a power source output voltage, a power source output current, or a power source output power.

9. The ultrasonic surgical assembly according to claim 1, further comprising:

a memory electrically connected to the cordless ultrasonic generator and operable to store a device use history; and

a device identifier communicatively coupled to the battery-holding compartment and operable to communicate information about the surgical handle to the battery, wherein the information includes at least one of a handle identifier, an information list of previous use, or a waveguide identifier.

10. An ultrasonic surgical assembly, comprising:

a waveguide;

a cordless ultrasonic-movement-generation assembly including a driving-wave generation circuit having a generator output, a securing connector, and a transducer electrically coupled to the generator output and having an output couple configured to connect the waveguide thereto;

a surgical handle, including;

a first handle body portion defining an aseptically sealable battery-holding compartment configured to aseptically hold the removable battery therein, and configured to electrically connect the removable battery to the ultrasonic-movement-generation assembly; and

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

a waveguide attachment dock operable to connect the waveguide thereto; and

an ultrasonic-movement-generation assembly dock configured to removably secure the second handle body portion to the securing connector and connect the waveguide in the waveguide attachment dock to the output couple through the second handle body portion.

11. The ultrasonic surgical assembly according to claim 10, wherein the driving-wave generation circuit comprises at least one of:

a control circuit, a drive circuit, or a matching circuit.

12. The ultrasonic surgical assembly according to claim 10, further comprising conductive power leads in the battery-holding compartment configured to electrically connect the removable battery to the ultrasonic-movement-generation assembly when the removable battery is aseptically sealed in the battery-holding compartment.

13. The ultrasonic surgical assembly according to claim 10, further comprising a movable compartment door connected to the first handle body portion and having:

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

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

14. The ultrasonic surgical assembly according to claim 10, wherein the first handle body portion forms a handgrip of the surgical handle.

15. The ultrasonic surgical assembly according to claim 10, wherein the removable battery includes a power source and a power-source controller, the power-source controller operable to maintain one of a power source output voltage, a power source output current, or a power source output power.
