摘要：
The electrosurgical systems and corresponding methods of the present disclosure involve an electrosurgical generator, sensing circuitry, and a controller. The electrosurgical generator includes a radio frequency (RF) output stage that supplies power to tissue. The sensing circuitry measures impedance of tissue. The controller controls the power supplied from the RF output stage to track a nonlinear power curve until the power supplied from the RF output stage has reached a predetermined peak power of the nonlinear power curve. The controller further determines whether a tissue reaction has occurred based on impedance measured by the sensing circuitry and controls the power supplied from the RF output stage during a cooling phase if the controller determines that a tissue reaction has occurred. The controller may further control the power supplied from the RF output stage to track a linear power curve.
