Abstract: An electrocautery unit includes a light source that may be molded to the electrocautery tip during the manufacturing process. The light source may be chosen by the manufacturer that will work with the electrical system used to power the electrocautery. The light source may be monopolor (on demand lighting when the user initiates the electrocautery), bipolar with constant illumination, or separately wired from the electrocautery device and using its own power supply and on and off switch. The shape and/or angle of the light source may be determined by the function desired by the user. A broad angled light source could be used for large areas needing homeostasis. A narrow light could be used to direct illumination directly ahead of the electrocautery unit. The light source may be a light emitting diode (LED), as such a light source may be reusable through gas sterilization or a single use disposable item.
