Abstract

An ultrasonic assembly that is removably connectable to an ultrasonic waveguide of an ultrasonic surgical handle includes a cordless ultrasonic-movement-generation assembly having an ultrasonic generator and an ultrasonic transducer electrically coupled to the generator and having an output couple, a shell housing therein the ultrasonic-movement-generation assembly and having a securing connection shaped to removably connect to the ultrasonic surgical handle. The output couple is operable to impart ultrasonic movement to the ultrasonic waveguide when the securing connection is connected to the ultrasonic surgical handle and the waveguide is connected to the output couple.

Claims

1. An ultrasonic assembly removably connectable to an ultrasonic waveguide of an ultrasonic surgical handle, the assembly comprising:

a cordless ultrasonic-movement-generation assembly having;

an ultrasonic generator; and

an ultrasonic transducer electrically coupled to the generator and having an output couple;

a shell;

housing therein the ultrasonic-movement-generation assembly; and

having a securing connection shaped to removably connect to the ultrasonic surgical handle; and

the output couple operable to impart ultrasonic movement to the ultrasonic waveguide when the securing connection is connected to the ultrasonic surgical handle and the waveguide is connected to the output couple.

2. The assembly according to claim 1, wherein the shell is aseptically sealed.

3. The assembly according to claim 1, wherein the securing connection is a rail.

4. The assembly according to claim 1, wherein the securing connection is an undercut slot.

5. The assembly according to claim 1, further comprising a sterilizable filter permitting venting after sterilization.

6. The assembly according to claim 1, wherein the shell has an outer surface and further comprises electrically communicating contacts on the outer surface and conductively connected to the generator for supplying power thereto.

7. An ultrasonic assembly removably connectable to an ultrasonic waveguide of an ultrasonic surgical handle, the assembly comprising:

a cordless ultrasonic-movement-generation assembly having;

an ultrasonic generator; and

an ultrasonic transducer electrically coupled to the generator and having an output couple;

a shell;

housing therein at least one of the generator and the transducer; and

having a securing connection shaped to removably connect to the ultrasonic surgical handle; and

the output couple operable to impart ultrasonic movement to the ultrasonic waveguide when the securing connection is connected to the ultrasonic surgical handle and the waveguide is connected to the output couple.

8. The assembly according to claim 7, wherein the shell is aseptically sealed.

9. The assembly according to claim 7, wherein the securing connection is one of a rail and an undercut slot.

10. The assembly according to claim 7, further comprising a sterilizable filter permitting venting after sterilization.

11. The assembly according to claim 7, wherein the shell has an outer surface and further comprises electrically communicating contacts on the outer surface and conductively connected to the generator for supplying power thereto.

12. An ultrasonic-movement-generation assembly to be removably connected to an ultrasonic waveguide of an ultrasonic surgical handle, the assembly comprising:

a cordless ultrasonic transducer having an external output couple operable to impart ultrasonic movement to the ultrasonic waveguide when the waveguide is connected to the output couple;

a tank circuit electrically connected to the transducer and tuned to match the transducer; and

an aseptically sealed assembly shell having;

disposed therein the transducer and the tank circuit; and

an external securing connection shaped to removably connect the shell to the ultrasonic surgical handle.

13. The assembly according to claim 12, wherein:

the tank circuit includes an internal driving-wave generation circuit having a generator output; and

the transducer is communicatively coupled to the generator output.

14. The assembly according to claim 13, wherein the driving-wave generation circuit comprises at least one of:

a control circuit;

a drive circuit; and

a matching circuit.

15. The assembly according to claim 13, wherein the transducer is rotatable with respect to the driving-wave generation circuit.

16. The assembly according to claim 12, wherein the transducer and the tank circuit are powered only by the surgical handle.

17. The assembly according to claim 12, wherein;

the surgical handle has an internal battery; and

the transducer and the tank circuit are powered only by the battery.

18. The assembly according to claim 12, wherein:

the waveguide has an identification type; and

the tank circuit is operable to vary at least one of a driving-wave output frequency and a driving-wave output power based on the identification type.
