Multiple function cauterizing instrument

摘要

A multiple function cauterizing instrument having a housing and an illuminating optical fiber extending from a lens, through the housing, to a high intensity light source for supplying incident light to the targeted tissue area to be cauterized. A viewing optical fiber extends from a wide angle camera lens, through the housing, to a video monitor for supplying to the monitor a visual image of the targeted tissue area. An exhaust channel extends from an intake vent, through the housing, to a source of vacuum to suction gas and fumes caused by cauterizing the tissue area. A plurality of heating elements or cauterizing tips are selectively moved through the housing between a retracted position at which the elements are shielded by the housing and an extended position at which the elements are advanced outwardly from the housing for contacting the tissue to be cauterized.
