摘要： A return electrode monitoring ("REM") system is disclosed. The REM system includes a return electrode pad having a pair of split electrode pads and a detection circuit coupled to the pair of split electrode pads. The detection circuit and the pair of split electrode pads are adapted to resonate across a predetermined resonance range. The REM system also includes a controller coupled to the detection circuit and configured to provide a sweeping drive signal to the detection circuit across the resonance range. The detection circuit generates a drive signal in response to the sweeping drive signal and the controller determines a complex impedance across the at least one pair of split electrode pads as a function of the drive signal.

摘要： The systems and methods of the present disclosure detect arcing patterns or impedance changes and adjust the level of electrosurgical energy provided to tissue based on the detected arcing patterns or impedance changes. In embodiments, the drag force imposed on the electrode or blade of an electrosurgical instrument may be controlled by adjusting the level of electrosurgical energy based on the detected arcing patterns or impedance changes. The arcing patterns or impedance changes may be detected by sensing voltage and/or current waveforms of the electrosurgical energy and analyzing the sensed voltage and/or current waveforms. The current and/or voltage waveform analysis may involve calculating impedance based on the sensed voltage and current waveforms and calculating changes in impedance over time. The waveform analysis may involve detecting harmonic distortion using FFTs, DFTs, Goertzel filters, polyphase demodulation techniques, and/or bandpass filters. The waveform analysis may involve determining a normalized difference or the average phase difference between the voltage and current waveforms.

摘要： Systems and methods for estimating tissue parameters, including mass of tissue to be treated and a thermal resistance scale factor between the tissue and an electrode of an energy delivery device, are disclosed. The method includes sensing tissue temperatures, estimating a mass of the tissue and a thermal resistance scale factor between the tissue and an electrode, and controlling an electrosurgical generator based on the estimated mass and the estimated thermal resistance scale factor. The method may be performed iteratively and noniteratively. The iterative method may employ a gradient descent algorithm that iteratively adds a derivative step to the estimates of the mass and thermal resistance scale factor until a condition is met. The non-iterative method includes selecting maximum and minimum temperature differences and estimating the mass and the thermal resistance scale factor based on a predetermined reduction point from the maximum temperature difference to the minimum temperature difference.
