Abstract

PURPOSE: To monitor a feedback electrode with low reaction with an electrosurgical knife current interference when monitoring is continued during an electrosurgical knife operation by adding the patient himself to the monitor of the continuity of a patient feedback circuit. CONSTITUTION: An electrosurgical knife generator 10 includes a known high-frequency oscillator 12 and an output amplifier 14 which generates an electrosurgical knife current. The electrosurgical knife current is fed back to the generator via a split feedback electrode 18 consisting of electrodes 20, 22 and two pieces of patient conductor cables 24 consisting of lead wires 26, 28. The primary winding 40 of a transformer 38 is connected to a patient impedance detecting circuit 42. The current is impressed to a threshold circuit to determine whether the impedance is within a range meeting the patient's physiological characteristics or not. This patient impedance detecting circuit 42 processes the voltage appearing between the conductors 20 and 22 so as to output EREM which is the magnitude of the impedance between the electrodes 20 and 22. This current is fed back to the circuit 42 by passing the electrode 20, the patient and through the electrode 22 and the conductor 28.
