发明名称 System and method for measuring initial tissue impedance
摘要 SYSTEM AND METHOD FOR MEASURING INITIAL TISSUE Abstract An electrosurgical system and method are disclosed. The system includes an s electrosurgical generator (20) adapted to supply electrosurgical energy to tissue. The generator (20) is further adapted to supply an electrical signal having at least one substantially constant value to tissue to determine initial tissue impedance response. The generator (20) includes sensor circuitry adapted to continuously monitor initial tissue impedance response, wherein the initial tissue impedance response includes one of an /o initial impedance, an impedance drop, an impedance minimum and a first impedance rise. The generator (20) also includes a microprocessor (25) adapted to generate at least one tissue parameter based as a function of the initial impedance, the impedance drop, the impedance minimum and the first impedance rise. The system also includes an electrosurgical instrument (10) including at least one active electrode (24) adapted to /5 apply electrosurgical energy to tissue for treatment.
