Abstract
To provide an electrosurgical device capable of improving the rate of nerve function preservation. [Solution] An electrosurgical device 1 used in surgical procedures comprises a control device 2 that generates low-frequency and high-frequency currents, and a handpiece 3 equipped with a scalpel tip electrode 33 capable of outputting either a low-frequency or high-frequency current to biological tissue. The handpiece 3 includes a diagnostic mode that outputs a low-frequency current from the scalpel tip electrode 33 to diagnose the presence or absence of nerves in the biological tissue in contact with the scalpel tip electrode 33, and an incision mode that outputs a high-frequency current from the scalpel tip electrode 33 to perform an incision of biological tissue. The control device 2 includes a control program 21 that controls the handpiece 3 to go through the diagnostic mode before entering the incision mode.
