Abstract:
1. A system for detecting faults within an electrosurgical instrument, the electrosurgical instrument including a shield and an active electrode, wherein the electrosurgical instrument is coupled with a return electrode, the system comprising: an electrosurgical generator coupled to the electrosurgical instrument and adapted to deliver power to the active electrode of the electrosurgical instrument; monitoring circuitry adapted to couple with the electrosurgical generator and the electrosurgical instrument, the monitoring circuitry comprising at least two of an identification element that indicates to the monitoring circuitry a class of the electrosurgical instrument; a threshold sensor for determining which of the active voltage, the active current and the shield power to utilize within the monitoring circuitry based at least in-part on information obtained from the identification element; wherein the monitoring circuitry measures at least two of the active voltage, the active current, and the shield power to determine whether a fault condition exists in the electrosurgical instrument.
