Abstract
The present invention relates, in general, to electrosurgical instruments and, more particularly, to a feedback light used in cooperation with an electrosurgical instrument. The present invention further comprises first and second moveable jaws. A first electrode is housed within the first moveable jaw and a second electrode is housed within the second moveable jaw, where the electrodes are connectable to a power source for providing an electric current between the electrodes. The present invention further comprises a feedback light connectable to a first lead and a second lead in order to form a second circuit, where the second circuit is adjacent to the first circuit in order to facilitate capacitive coupling between the first and second circuits in order to light a feedback light.
