ABSTRACT:
An electrode for use in an electrosurgical aural procedure known as a myringotomy for incising tissue of the tympanic membrane. In a preferred embodiment, the electrode is characterized by a bare active tip portion terminating a colinear electrically-insulated electrode shaft offset at an angle from a handle. The tissue incising is effected with the bare tip at a depth stopped by a shoulder between the bare tip and the adjacent portions of the electrode shaft. The electrical insulation prevents accidental burns to the patient and allows the physician to use these insulated parts to help position and guide the active tip portion during the surgical procedure.
