ABSTRACT:
An electrosurgical system having a visual indicator is provided. In a first embodiment, the electrosurgical system includes an active electrode coupled to a power supply for providing electrosurgical energy from the power supply to a tissue area and a return electrode separated from the active electrode, the return electrode being adapted to receive a current flowing through the tissue. The electrosurgical system further includes a lamp in electrical communication with the active and return electrodes, wherein the neon bulb is illuminated when the current flowing through the tissue exceeds a predetermined threshold. In a further embodiment, the electrosurgical system includes a second lamp illuminated when a voltage through the tissue is greater than a predetermined threshold. In another embodiment, a monopolar electrosurgical device includes a visual indicator for indicating conditions at an area of affected tissue. The visual indicator circuit includes a transformer having a secondary winding, a wire through the transformer forming the primary winding, a series resistor coupled in series with the secondary winding, and a type NE-2 neon bulb coupled in series with the series resistor, wherein the lamp is illuminated when the current through the wire is greater than a predetermined threshold.
