Abstract

PURPOSE: To measure the electric characteristic of a diseased part before and after cauterizing by allowing a selecting means to constitute a circuit between an electric characteristic measuring means and a probe at the same time as the circuit formed by a high frequency generating means and the probe is opened by the selecting means.
CONSTITUTION: Electrical continuity is formed with an external electrode 14 through a spherical electrode 17 and a vital structure 26, while the internal electrode 11 is connected with an analyzer 7 via a common contact 4a and a normally closed contact 4c, to provide measurability for electric characteristics. A relay driver circuit 8 is actuated to change over a high frequency coaxial relay 4, and the common contact 4a is connected with a normally open contact 4c. Through a coaxial cable 19 a high frequency signal from a high frequency generating device 6 is fed to a vital structure 26 by the electrodes 11, 14 via the normally closed contact 4b and common contact 4a, and the diseased part undergoes cauterizing. If the relay driver circuit 8 is deactuated after this cauterizing, the high frequency coaxial relay 4 is changed over again to the normally closed contact 4c side, and the analyzer 7 measures the electric characteristic of the vital structure 26 after cauterizing. This permits knowing whether cauterizing has been made with good performance with appropriate value according to the electric characteristic.
