Abstract
An electrosurgical system for providing an electrosurgical signal to a patient is disclosed. The electrosurgical system includes a control circuit, wherein the control circuit is programmed to: provide the electrosurgical signal to a first electrode and a second electrode, receive a plurality of input variables, wherein the plurality of input variables are indicative of a short being either present or absent between the first electrode and the second electrode, and apply a short detection algorithm to the plurality of input variables to indicate either a short circuit or no short circuit between the first electrode and the second electrode during the provision of the electrosurgical signal. The plurality of input variables may include at least one impedance level between the first electrode and the second electrodes during the provision of the electrosurgical signal. The short detection algorithm applied may include a fuzzy logic algorithm, a neural network algorithm, or neuro-fuzzy algorithm.
