Abstract

A return pad cable connector, in accordance with the present disclosure, for use with a disposable return pad, includes a cord having a conductive wire disposed therethrough which conductive wire interconnects the return pad cable connector to an electrosurgical energy source. The return pad further includes a connector operatively coupled to the cord, the connector having a conductive surface which is selectively engageable with a corresponding conductive surface disposed on the return pad, the conductive surface of the connector including a conductive adhesive disposed thereon and a non-conductive adhesive disposed above the periphery of the conductive surface of the connector for engagement with a corresponding non-conductive adhesive disposed above the periphery of the conductive surface of the return pad. The connector can include a magnet for magnetically coupling the connector to the conductive surface disposed on the return pad.

Claims

1. A return pad cable connector for use with a disposable return pad, comprising:

a cord having a conductive wire disposed therethrough which connects to an electrosurgical energy source;

a connector which operatively couples to the cord having;

a conductive cord surface which is selectively engageable with a corresponding conductive return pad surface disposed on the return pad, the conductive cord surface of the connector including a conductive adhesive disposed thereon; and

a non-conductive adhesive disposed about the periphery of the conductive cord surface of the connector for engagement with a corresponding non-conductive adhesive disposed about the periphery of the conductive return pad surface of the return pad.

2. The return pad cable connector according to claim 1, wherein the connector includes at least two conductive surfaces that correspondingly mate with at least two conductive surfaces on the return pad.

3. The return pad cable connector according to claim 1, wherein the return pad connector selectably electrically couples the removable return pad to an electrosurgical generator.

4. A return pad cable connector for use with a disposable return pad, comprising:

a cord having a conductive wire disposed therethrough which connects to an electrosurgical energy source;

a connector which operatively couples to the cord, the connector including;

a conductive cord surface which is selectively engageable with a corresponding conductive return pad surface disposed on the return pad, the conductive cord surface of the connector including a conductive adhesive disposed thereon;

a non-conductive adhesive disposed about the periphery of the conductive cord surface of the connector for engagement with a corresponding non-conductive adhesive disposed about the periphery of the conductive return pad surface of the return pad;

a base element including a handle and a fixed jaw having a conductive jaw surface affixed to an inner surface thereof, and wherein the distal end of said conductive wire passes through the base element and operatively engages the conductive jaw surface; and

a return pad clamp pivotally mounted to the base element, the connector being positionable between an open position wherein the return pad clamp is spaced from the fixed jaw and a closed position wherein the return pad clamp is in contact with the fixed jaw.

5. The return pad cable connector according to claim 4, wherein the return pad clamp includes a moveable jaw and a clamping lever depending therefrom and extending along the handle.

6. The return pad cable connector according to claim 5, wherein the connector further includes a locking mechanism adapted to selectively maintain the connector in the closed position.

7. The return pad cable connector according to claim 6, wherein the locking mechanism includes a latch projecting from the clamping lever of the return pad clamp, and a locking rail projecting from a locking aperture formed in the handle, wherein the latch operatively engages the locking rail.

8. The return pad cable connector according to claim 4, wherein the return pad includes an interface having the conductive return pad surface disposed thereon.

9. The return pad cable connector according to claim 8, wherein the conductive return pad surface of the interface is adapted to operatively engage the conductive jaw surface of the base element of the connector, thereby establishing an electrical connection between the return pad and the connector.

10. The return pad cable connector according to claim 9, wherein an interface adhesive is disposed between the conductive return pad surface of the interface of the return pad and the conductive surface of the base element.

11. The return pad cable connector according to claim 10, wherein the interface adhesive is conductive.

12. A return pad cable connector for use with a disposable return pad, comprising:

a cord having a conductive wire disposed therethrough which connects to an electrosurgical energy source;

a connector which operatively couples to the cord having a conductive adhesive and a non-conductive adhesive, a base element including a handle and a fixed jaw having a conductive jaw surface affixed to an inner surface thereof;

wherein the distal end of said conductive wire passes through the base element and operatively engages the conductive jaw surface;

a return pad clamp pivotally mounted to the base element; and

the connector being positionable between an open position wherein the return pad clamp is spaced from the fixed jaw and a closed position wherein the return pad clamp is in contact with the fixed jaw.

13. A return pad cable device, comprising:

a connector, including;

a base element; and

a return pad clamp pivotally mounted to the base element;

a conductive adhesive disposed on one of the base element and the return pad clamp of the connector; and

a non-conductive adhesive disposed the other of the base element and the return pad clamp of the connector.
