摘要： An electrosurgical generator having a source of electrosurgical energy connected to a patient and including control circuitry for decreasing the output power from the source with increasing patient impedance, the rate of power decrease being substantially greater than that which would result if the output voltage from the source were maintained constant over the range of increasing patient impedance. The control circuitry may, in particular, decrease the output power over the range of increasing patient impedance in accordance with the square of the impedance.
