  • Publication number: 20200078089
    Abstract: Aspects of the present disclosure are presented for systems and methods for identifying characteristics of a return pad in a monopolar electrosurgical system using contact quality monitoring (CQM) and near field communication (NFC) signals. In some aspects, resistance or impedance materials are sensed that may help identify what kind of return pad is being used, including what is the structure of the pad. In some aspects, NFC signals are used to identify characteristics of the return pad. In some aspects, the grounding or return pad may include two separate materials that form an interconnecting or interwoven mesh and both act as non-active electrodes when both contact the patient. A non-zero impedance may separate conductive lines connecting the two separate materials that may be analyzed to obtain a defining signature about that is linked to structural characteristics about the return pad.

  • Publication number: 20190274748
    Abstract: Methods, devices, and systems for measuring impedance for electrosurgical tools are provided. In general, a surgical device configured to apply energy to tissue can be configured to deliver the energy to the tissue based on an impedance of the tissue. The impedance can be determined based on an electrical signal transmitted to the tissue via the surgical device, such as by one or more electrodes of the surgical device that are in contact with the tissue. The impedance determination can include determining both real and imaginary components of the impedance, thereby allowing a phase shift to be identified and for an actual impedance to be determined by correcting for the phase shift. The actual impedance of the tissue can be used to identify a type of the tissue.
