Patent ID: 7128742

Claim:
An electric operation apparatus comprising: a high-frequency generating device which generates high-frequency current for treating the body anatomy; an active electrode which supplies to adapted to supply the body anatomy with the high-frequency current generated by the high-frequency generating device; a solution supply device which supplies a conductive solution around the active electrode; a return electrode which returns, via the conductive solution supplied by the solution supply device, the high-frequency current supplied to the body anatomy from the active electrode in the conductive solution; a sensor which detects a conductive state of the high-frequency current that flows between the active electrode and the return electrode; a control device which determines a state of bubbles generated around the active electrode and which changes an operation mode, based on the conductive state of the high-frequency current detected by the sensor, the control device has a first operation mode for starting the discharge operation using the active electrode and a second operation mode for changing the conductive state of the high-frequency current after the start of discharge operation in the first operation mode; and an air supply device which supplies air near the active electrode arranged in the conductive solution, the control device controlling the air supply device and changing the operation mode.
