Abstract

An electrosurgical instrument that reduces the amount of fatigue experienced by a physician performing electrosurgery includes a hand piece with a utility conduit connected to the hand piece at a central portion of the hand piece. The utility conduit can include an electrical cable and a smoke/fluid evacuation hose. The hand piece can include a channel system that receives a portion of the utility conduit therein and allows a physician to adjust the location on the hand piece at which the utility conduit exits the hand piece. Adjusting the location on the hand piece at which the utility conduit exits the hand piece can reduce the resistance to the movement of the electrosurgical instrument created by the weight of the utility conduit, which leads to less fatigue in a physician'"'"'s hand during electrosurgery.

Claims

1. An electrosurgical instrument for use during an electrosurgical procedure, the electrosurgical instrument comprising a hand piece and a utility conduit configured to transmit electrical energy from an electrosurgical generator to the hand piece and to convey smoke/fluid away from a surgical site, the hand piece comprising:

a proximal end and a distal end, the distal end having an intake therein;

a receptacle disposed between the proximal end and the distal end and configured to have the utility conduit connected thereto;

an input device configured to selectively control an operation of the electrosurgical instrument; and

a channel system configured to selectively receive and retain therein at least a portion of the utility conduit, wherein the channel system enables an exit location of the utility conduit from the channel system to be selectively adjusted such that the exit location may be selectively moved along a length of the hand piece between the receptacle and the proximal end.

2. The electrosurgical instrument of claim 1, wherein the channel system comprises a longitudinal channel extending from the receptacle to the proximal end of the hand piece.

3. The electrosurgical instrument of claim 2, wherein the longitudinal channel comprises a plurality of detents spaced along a length of the longitudinal channel, the plurality of detents being configured to selectively retain at least a portion of the utility conduit within the longitudinal channel.

4. The electrosurgical instrument of claim 3, wherein the longitudinal channel further defines a plurality of predefined, discrete exit locations from which the electrical cable can exit the longitudinal channel.

5. The electrosurgical instrument of claim 4, wherein the plurality of predefined, discrete exit locations are formed along the length of the longitudinal channel and between the plurality of detents.

6. The electrosurgical instrument of claim 5, wherein the channel system is configured to enable a user of the electrosurgical instrument to adjust the utility conduit to select an exit location from the plurality of predefined, discrete exit locations from which the utility conduit may exit the channel system.

7. The electrosurgical instrument of claim 1, wherein the utility conduit comprises:

a cable configured to transmit electrical energy from the electrosurgical generator to the hand piece; and

a smoke/fluid evacuation hose configured to convey smoke/fluid away from the surgical site.

8. The electrosurgical instrument of claim 1, wherein the intake in the distal end is configured to receive a conductive electrode tip at least partially therein.

9. The electrosurgical instrument of claim 1, wherein the utility conduit is configured to be held in a user'"'"'s hand after exiting the channel system.

10. An electrosurgical instrument for use during an electrosurgical procedure to transmit electrical energy from an electrosurgical generator to tissue of a patient and to remove smoke/fluid from a surgical site, the electrosurgical instrument comprising:

a utility conduit comprising;

an electrical cable configured to transmit the electrical energy from the electrosurgical generator; and

a smoke/fluid evacuation hose configured to convey the smoke/fluid away from the surgical site; and

a hand piece having a proximal end, a distal end, and a central portion disposed therebetween, the central portion having a receptacle to which the utility conduit is connected, the hand piece further comprising a channel system configured to selectively receive and retain therein at least a portion of the utility conduit, wherein the channel system enables a user of the electrosurgical instrument to selectively adjust an exit location for the utility conduit to selectively move the exit location along at least a portion of a length of the hand piece.

11. The electrosurgical instrument of claim 10, wherein the distal end of the hand piece comprises an intake that is in fluid communication with the smoke/fluid evacuation hose.

12. The electrosurgical instrument of claim 10, wherein the channel system comprises a longitudinal channel that extends from the receptacle toward the proximal end.

13. The electrosurgical instrument of claim 12, wherein the longitudinal channel is configured to selectively and removably receive at least a portion of the utility conduit therein such that the utility conduit exits the channel system between the receptacle and the proximal end, and wherein the user of the electrosurgical instrument can selectively position the utility conduit within the longitudinal channel to select the exit location of the utility conduit from the channel system.

14. The electrosurgical instrument of claim 10, wherein the channel system comprises a side channel that extends from the receptacle to one side of the hand piece and is configured to selectively and removably receive at least a portion of the utility conduit therein such that the utility conduit exits the channel system from the central portion of the hand piece.

15. The electrosurgical instrument of claim 10, wherein the distal end of the hand piece is configured to receive a conductive electrode tip at least partially therein.

16. The electrosurgical instrument of claim 10, wherein the utility conduit is corrugated or has detents formed on an outer surface thereof.

17. The electrosurgical instrument of claim 10, wherein the channel system comprises a plurality of discrete exit locations between the receptacle and the proximal end.

18. The electrosurgical instrument of claim 17, wherein the plurality of discrete exit locations are defined by detents formed in the channel system.

19. The electrosurgical instrument of claim 10, wherein the smoke/fluid evacuation hose is configured to be used as a handle.
