Abstract
An electrosurgical system monitors and visually indicates a degree of contact between a return electrode and a patient's skin. The system includes an electrosurgical generator and a return pad. The return pad includes a return electrode, a lighting element, and a cable electrically and mechanically coupling the return electrode to the generator. The lighting element is configured to emit light based on the degree of contact between the return electrode and the patient's tissue (e.g., skin).
