Abstract: A surface ablation system includes an electrosurgical generator, and elongated shaft, a plug, and a circuit assembly. The elongated shaft includes a proximal end portion and a distal end portion. The plug is supported on the distal end portion of the elongated shaft. The circuit assembly is supported on the plug and in electrical communication with the electrosurgical generator. The circuit assembly includes spaced-apart traces positioned in arrays about the plug. Each of the traces is configured to emit electrosurgical energy along the arrays to treat tissue positioned adjacent to the traces.

Abstract: The electrosurgical systems and methods of the present disclosure monitor power dosage delivered to tissue being treated with improved speed and accuracy. The electrosurgical systems include an output stage, sensors, analog all-pass filters, an analog multiplier, an average power calculation circuit, and a controller. The output stage generates electrosurgical energy to treat tissue. The plurality of sensors sense voltage and current waveforms of the generated electrosurgical energy. The plurality of analog all-pass filters filter the sensed voltage and current waveforms. The plurality of analog all-pass filter may have lagging or leading phase. The analog multiplier multiplies the filtered voltage and current waveforms to obtain a real power waveform. The average power calculation circuit calculates a real average power based on the real power waveform. The controller then generates a control signal to control the output stage based on the real average power.
