Abstract
In an electrosurgical power supply apparatus combined with an electronic endoscope system, there is provided an electrosurgical signal generator. The electrosurgical signal generator includes PROM for previously storing data representative of electrosurgical high-frequency currents. In response to a selection signal of an electrosurgical operation mode, the data is read out from PROM to produce the electrosurgical high-frequency current corresponding to the selected electrosurgical operation mode.
