AI Technical Summary
Technical Problem
Existing surgical devices that combine nerve diagnosis and incision functions risk accidental incisions due to operator error, leading to reduced nerve function preservation after surgery.
Method used
An electrosurgical device with a control program that requires sequential operation of multiple switches to transition between diagnostic and incision modes, ensuring that nerve diagnosis occurs before incision, thereby reducing accidental cuts.
Benefits of technology
The device improves nerve function preservation by preventing accidental incisions during nerve diagnosis, enhancing surgical efficiency and accuracy.

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.
