Abstract

An auxiliary return system for use with a bipolar electrosurgical device includes a tissue guard defining an open proximal end, an open distal end, and a lumen extending therethrough between the open proximal end and the open distal end. A ground plate is disposed along an inner peripheral surface of the lumen and is operably coupled to a first end of a ground wire extending from the tissue guard. A coupling is included having a bore defined therein for receiving a cable from an electrosurgical device therethrough, the cable including active and ground leads. The coupling has a flange extending therefrom defining a receptacle therein configured to operably receive a plug connected to a second end of the ground wire. The receptacle is configured to provide electrical continuity between the ground lead disposed within the cable and the plug coupled to the ground wire which, in turn, provides electrical continuity to the ground plate.

Claims (7)

1. A tissue guard for use with a bipolar an electrosurgical device, comprising:

a body defining an open proximal end, an open distal end, and a lumen extending therethrough between the open proximal end and the open distal end, the body including an elongated channel defined therealong, the elongated channel terminating in a pocket defined through an outer peripheral surface thereof, the pocket housing a wire connector therein, the distal end of the body being oblong and including a long petal and a short petal, the elongated channel providing rigidity to the long petal;

a ground tab disposed along an inner peripheral surface of the lumen in concentric registration with the pocket and in electrical communication with the connector;

an electrically conductive layer disposed along an inner peripheral surface of the lumen of the body, the electrically conductive layer disposed in electrical communication with the ground tab; and

a ground wire electrically coupled at a first end to the wire connector and extending through the elongated channel to a second end adapted to electrically engage a coupling attached to a return from the electrosurgical device thereby providing electrical continuity between the electrically conductive layer and the return.

2. The tissue guard according to claim 1 , wherein the electrosurgical device is an electrosurgical pencil.

3. The tissue guard according to claim 1 , wherein the elongated channel is formed by adding a material atop the body to define the elongated channel on an outer peripheral surface of the body, the material having a higher durometer rating than the material used for the body.
