摘要：A device and method for detecting faults in a shield of an electrosurgicalinstrument is described. The device has a relay configured to selectively interrupt powerto the electrosurgical instrument, monitoring circuitry configured to monitor a shield in
the electrosurgical instrument, control circuitry to control the relay, and a battery powersource. The monitoring circuitry has an envelope detector and an detected averageshield current detector. The monitoring circuitry is configured to compare a shieldcurrent peak value to a shield current peak threshold value, and to compare an detectedaverage shield current value to an detected average shield current threshold value. Thedevice is further configured to operatively couple an active electrode of anelectrosurgical instrument and a return electrode to an electrosurgical generator.
