Abstract
A control device includes: a power source configured to supply a high frequency power to a treatment instrument configured to treat a living tissue; a detecting circuit configured to sequentially detect a phase difference between a voltage and a current of the high frequency power supplied to the treatment instrument; and a processor configured to control operation of the power source, the processor being configured to sequentially calculate a variation of the phase difference detected by the detecting circuit, compare the calculated variation of the phase difference with a first threshold set for a variation of a phase difference, and perform reduction processing to reduce output of the high frequency power to be supplied to the treatment instrument when it is determined that the calculated variation of the phase difference is equal to or smaller than the first threshold.
