An illumination device for use with a standard electrocautery pencil is described, having a distal end capable of telescoping for use with cautery extenders. The illumination device also has a light source on the distal end to reduce shadow problems, and a tube is provided for evacuation of smoke from the surgical field. The device is sized to fit on any standard electrocautery pencil. The light-emitting component on the device reduces shadows and evacuates smoke from the treatment sight without necessitating purchase of a new electrocautery device.
