Abstract

The present disclosure relates to a method for performing electrosurgery. The disclosed method includes providing a wireless, bite-activated switch configured for use within a surgeon'"'"'s mouth. The disclosed switch includes an activator, a transponder, and an antenna. The switch communicates with an electrosurgical energy source, such as without limitation, an electrosurgical RF or microwave generator, to convey the state of the switch and activate the generator. The disclosed method provides providing the wireless switch with a unique identifier and associating the generator with the unique switch to ensure only the intended switch can control the electrosurgical generator.

Claims

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

providing a wireless switch unit comprising;

a resilient housing configured for insertion within a user'"'"'s mouth;

an activator disposed within the housing;

an antenna; and

a transponder operatively coupled to the activator and the antenna;

providing an electrosurgical system unit comprising;

an interrogator; and

an electrosurgical energy source operably coupled to the interrogator;

transmitting an interrogatory signal including an identifier to the transponder;

receiving the interrogatory signal at the transponder;

sensing the state of the activator;

transmitting in response to the interrogatory signal a response signal conveying the state of the activator; and

receiving the response signal at the interrogator.

2. The method according to claim 1, further comprising the steps of:

activating the electrosurgical energy source in response to a response signal conveying an activated activator state; and

deactivating the electrosurgical energy source in response to a response signal conveying a de-activated activator state.

3. The method according to claim 1, further comprising the steps of:

generating a first indication in response to a response signal conveying an activated activator state; and

generating a second indication in response to a response signal conveying a de-activated activator state.

4. The method according to claim 3, wherein the first indication is selected from the group consisting of an audio indication, a visual indication, and a haptic indication.

5. The method according to claim 3, wherein the second indication is selected from the group consisting of an audio indication, a visual indication, and a haptic indication.

6. The method according to claim 1, further comprising the steps of:

associating a unique identifier with the wireless switch unit;

transmitting in response to the interrogatory signal a response signal conveying the unique identifier of the wireless switch;

receiving the response signal;

storing the unique identifier of the wireless switch;

comparing the stored unique identifier to a unique identifier conveyed in a subsequent response signal; and

ignoring the subsequent response signal if the unique identifier conveyed therein differs from the stored unique identifier.

7. The method according to claim 6, wherein the stored unique identifier is cleared in response to a clearing event.

8. The method according to claim 7, wherein the clearing event is selected from the group consisting of a user input, power-cycling the electrosurgical system unit, and the expiration of a predetermined time period.

9. The method according to claim 1, further comprising the steps of:

activating the electrosurgical energy source in response to a first response signal conveying an activated activator state;

receiving a subsequent response signal conveying a de-activated activator state; and

deactivating the electrosurgical energy source in response to a second response signal conveying an activated activator state.

10. The method according to claim 1, further comprising the step of activating the electrosurgical energy source for a predetermined period of time in response to a response signal conveying an activated activator state.
