Abstract
An electrocautery surgical device comprising a battery source and radio-frequency signal generating circuitry electrically coupled to the battery source and operable to deliver power. In an exemplary embodiment, the radio-frequency signal generating circuitry comprises a transformer having a primary winding and a secondary winding wherein the secondary winding is comprised of a first secondary sub-winding and a second secondary sub-winding, at least one switching component electrically coupled to the first and second secondary sub-windings and operable to switch between engaging the first secondary sub-winding and engaging the second secondary sub-winding such that a current induced by the primary winding flows through either the first secondary sub-winding or the second secondary sub-winding, wherein the first and second secondary sub-windings have a different number of turns such that the radio-frequency signal generating circuitry produces a different impedance value depending on which of the first or second secondary sub-windings is engaged.
