VARIABLE CAPACITIVE ELECTRODE PAD

摘要

An electrosurgical system is disclosed. The system includes one or more variable capacitive pads including one or more pairs of split electrodes arranged in a capacitive configuration, wherein the pair of split electrodes is adapted to connect to an electrosurgical generator. The system also includes a return electrode monitoring system coupled to the pair(s) of split electrodes and is configured to map an initial capacitance between the split electrodes with substantially full adherence of the variable capacitive pad to the patient and determine an adherence factor of the variable capacitance pad as a function of a change i n capacitance between the pair(s) of split electrodes with respect to the map of the initial capacitance indicative of substantially full adherence.
