Abstract

Systems, methods, and instruments associated with controlling the operating modes of an electrosurgical instrument using control signals delivered in a wireless manner from the electrosurgical instrument to an electrosurgical generator. The electrosurgical instrument transmits wireless control signals to the electrosurgical generator to initiate delivery of electrosurgical energy. The control signals are delivered to the electrosurgical generator without the need for a conductive cord extending between the electrosurgical generator and the electrosurgical instrument. The energy is delivered to the electrosurgical instrument, in response to the wireless control signals, along a path through an electrode and the physician utilizing the electrosurgical instrument and/or a conductive path external to the physician. The electrode upon which the physician rests provides a path for the electrosurgical energy and optionally prevents burning of the physician during an electrosurgical procedure.

Claims

1. A method for performing electrosurgery, the method comprising:

positioning an electrosurgical instrument in close proximity to tissue in preparation for performing electrosurgery; and

with the physician providing a portion of an electrical path between an electrosurgical generator and the electrosurgical instrument, delivering electrosurgical energy to the electrosurgical instrument along the electrical path such that at least a portion of the electrosurgical energy passes through the physician as the electrosurgical energy is delivered from the electrosurgical generator to the electrosurgical instrument.

2. The method as recited in claim 1, further comprising coupling a first electrical contact operatively associated with the electrical instrument with a second electrical contact supported by the physician.

3. The method as recited in claim 2, further comprising coupling the first electrical contact with the second electrical contact formed in a glove wearable by the physician.

4. The method as recited in claim 2, further comprising coupling the first electrical contact with the second electrical contact formed as a glove wearable by the physician.

5. The method as recited in claim 1, further comprising transmitting a control signal to the electrosurgical generator to deliver the electrosurgical energy to the electrosurgical instrument.

6. The method as recited in claim 5, wherein transmitting the control signal further comprises transmitting the control signal wirelessly to the electrosurgical generator.

7. A method for performing electrosurgery, the method comprising:

positioning an electrosurgical instrument in close proximity to tissue, the electrosurgical instrument comprising at least one input device manipulatable to select an operating mode of the electrosurgical instrument;

transmitting a wireless control signal from the electrosurgical instrument to an electrosurgical generator to identify the selected operating mode of the electrosurgical instrument; and

following delivery of the wireless control signal, and with the physician providing a portion of an electrical path between the electrosurgical generator and the electrosurgical instrument, delivering radio-frequency energy based upon the selected operating mode of the electrosurgical instrument to the electrosurgical instrument along the electrical path such that the physician'"'"'s body conveys at least a portion of the radio-frequency energy between the electrosurgical generator and the electrosurgical instrument.

8. The method as recited in claim 7, wherein positioning the electrosurgical instrument further comprises coupling a first electrical contact of the electrical instrument with a second electrical contact supported by the physician.

9. The method as recited in claim 8, wherein coupling the first electrical contact further comprises coupling the first electrical contact with the second electrical contact formed in a glove wearable by the physician.

10. The method as recited in claim 8, wherein coupling the first electrical contact further comprises coupling the first electrical contact with the second electrical contact formed as a glove wearable by the physician.

11. The method as recited in claim 7, further comprising receiving the wireless control signal and processing the wireless control signal to identify the selected operating mode.

12. The method as recited in claim 7, further comprising manipulating the at least one input device during delivery of the radio-frequency energy and terminating delivery of the radio-frequency energy upon ceasing manipulation of the at least one input device.

13. The method as recited in claim 7, further comprising selectively manipulating the at least one input device to vary the selected operating mode of the electrosurgical instrument.

14. A method for performing electrosurgery, the method comprising:

positioning an electrosurgical instrument in close proximity to tissue, the electrosurgical instrument comprising at least one input device manipulatable to select an operating mode of the electrosurgical instrument and a wireless transmitter;

transmitting a control signal from the electrosurgical instrument toward an electrosurgical generator, the control signal representing a selected operating mode of the electrosurgical instrument; and

with the physician providing a portion of an electrical path between the electrosurgical generator and the electrosurgical instrument, delivering radio-frequency energy based upon the selected operating mode of the electrosurgical instrument to the electrosurgical instrument along the electrical path such that at least a portion of the radio-frequency energy passes through the physician as the radio-frequency energy is delivered from the electrosurgical generator to the electrosurgical instrument.

15. The method as recited in claim 14, wherein the signal comprises a signal having a wavelength selected from the group consisting of radio, microwave, or infrared.

16. The method as recited in claim 14, further comprising receiving the control signal at the generator and processing the control signal to identify the selected operating mode.

17. The method as recited in claim 14, further comprising coupling a first electrical contact operatively associated with the electrical instrument with a second electrical contact supported by the physician.

18. The method as recited in claim 17, further comprising coupling the first electrical contact with the second electrical contact formed in a glove wearable by the physician, the second electrical contact selectively coupling with an electrical trace supported by a physician gown.

19. The method as recited in claim 17, further comprising coupling the first electrical contact with the second electrical contact formed as a glove wearable by the physician.

20. The method as recited in claim 14, wherein delivering the radio-frequency energy comprises delivering the radio-frequency:

from the electrosurgical generator towards a return electrode upon which the physician stands during electrosurgery; and

from the return electrode through the physician to the electrosurgical instrument.
