Abstract

A surgical system that illuminates a surgical site using one or more illumination means is powered by radiofrequency energy produced by an electrosurgical generator. Illumination may occur whether or not current is being delivered from an active electrode to target tissue.

Claims (37)

1. A system for illuminating a surgical field, said system comprising:

an electrosurgery instrument having an illumination element for illuminating the surgical field;

a secondary power source;

a connector plug operably coupled to the electrosurgery instrument and having a receptacle for receiving the secondary power source; and

a power conductor extending from the connector plug to a proximal end of the electrosurgery instrument,

wherein the secondary power source is in the receptacle of the connector plug and operably coupled with the illumination element, and

wherein the connector plug is configured to plug into an electrosurgical generator.

2. The system of claim 1 , further comprising:

a return electrode adapter operably coupled to the electrosurgical generator,

wherein the power conductor is configured to carry power from the connector plug to the electrosurgery instrument,

wherein the illumination element receives power only from the secondary power source, and the electrosurgery instrument receives power only from the power conductor.

3. The system of claim 1 , wherein the connector plug further comprises:

at least one contact configured to electrically engage with a contact on the secondary power source; and

at least one connector pin.

4. The system of claim 1 , wherein the secondary power source comprises a battery or a capacitor.

5. The system of claim 1 , wherein the secondary power source is disposed in a sleeve to form a secondary power source assembly, and

wherein the secondary power source assembly is disposed in the receptacle.

6. The system of claim 5 , wherein the secondary power source assembly is releasably attached to the connector plug.

7. The system of claim 2 , wherein the secondary power source is removable from the receptacle while the connector plug is engaged with the electrosurgical generator and without interrupting operation of an electrosurgical device.

8. The system of claim 2 , wherein the secondary power source is removable while power is flowing from the electrosurgical generator to an electrosurgery device.

9. A method for illuminating or facilitating treatment of a surgical field, said method comprising:

providing an electrosurgery instrument having an illumination element for illuminating the surgical field;

providing a connector plug coupled to the electrosurgery instrument, the connector plug having a receptacle receiving a secondary power source, wherein a power conductor extends from the connector plug to a proximal end of the electrosurgery instrument;

energizing the illumination element with the secondary power source in the receptacle of the connector plug; and

illuminating the surgical field with light from the illumination element.

10. The method of claim 9 , further comprising engaging at least one contact on the connector plug with a contact on the secondary power source.

11. The method of claim 9 , further comprising inserting the secondary power source into the receptacle or removing the secondary power source from the receptacle, wherein the secondary power source comprises a battery or a capacitor.

12. The method of claim 9 , further comprising disposing the secondary power source into a sleeve thereby forming a secondary power source assembly and disposing the secondary power source assembly into the receptacle.

13. The method of claim 12 , further comprising attaching the secondary power source assembly to the connector plug or releasing the secondary power source assembly from the connector plug.

14. The method of claim 9 , further comprising replacing the secondary power source outside of the surgical field.

15. The method of claim 9 , further comprising electrosurgically cutting or coagulating tissue while illuminating the surgical field.

16. The method of claim 9 , wherein the surgical field is illuminated without electrosurgically cutting or electrosurgically coagulating tissue in the surgical field.

17. The method of claim 9 , further comprising:

providing other electrically activated device requiring power for operation and configured to facilitate treatment in the surgical field; and

energizing the other electrically activated device with the secondary power source in the receptacle of the connector plug,

wherein the other device comprises a camera or a sensor and facilitating treatment comprises capturing an image of the surgical field or sensing a characteristic of the surgical field.

18. The method of claim 9 , wherein the illumination element or the other device is coupled to a telescoping tube, the method further comprising moving the illumination element or the other device toward or away from the surgical field by slidably moving the telescoping tube.
