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

2. 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 surface which is selectively engageable with a corresponding conductive surface disposed on the return pad; and

an adhesive provided on at least one of the connector and the return pad.

3. The return pad cable connector according to claim 2, wherein the connector includes at least one conductive surface which correspondingly mates with at least one conductive surface on the return pad, the conductive surface of the connector including a border therearound for engaging a border around the conductive surface of the return pad, wherein the adhesive is provided on at least one of the conductive surface of the connector, the conductive surface of the return pad, the border surrounding the conductive surface of the connector and the border surrounding the conductive surface of the return pad.

4. The return pad cable connector according to claim 2, wherein at least the adhesive provided on the conductive surface of the return pad is a conductive adhesive.
