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 device, comprising:

a connector, including;

a base element;

a return pad clamp;

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

a non-conductive adhesive disposed at least one of the base element and the return pad clamp.

2. The return pad cable device of claim 1, wherein the return pad clamp is pivotally mounted to the base element.

3. The return pad cable device of claim 1, wherein the connector further includes a locking mechanism adapted to selectively maintain the connector in a desired position.

4. The return pad cable device of claim 1, wherein the connector is configured to electrically couple a return pad to an electrosurgical generator.

5. A return pad cable device, comprising:

a connector;

at least one conductive adhesive disposed on at least a portion of the connector; and

at least one non-conductive adhesive disposed on at least another portion of the connector.

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

7. The return pad cable device of claim 5, wherein the connector is configured to electrically couple a return pad to an electrosurgical generator.

8. An electrosurgical system, comprising:

a cord adapted to connect to a source of electrosurgical energy; and

a connector operatively coupled to the cord and which is engagable with a return pad, the connector including at least one conductive adhesive and at least one non-conductive adhesive disposed thereon.

9. The electrosurgical system of claim 8, further including at least one return pad, the at least one return pad including an interface having a conductive return pad surface disposed thereon.
