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.

Abstract: An energy treatment instrument includes a first grasping piece, and a second grasping piece which opens or closes relative to the first grasping piece and which grasps a blood vessel between the first grasping piece and the second grasping piece. In accordance with the kind of blood vessel grasped between the first grasping piece and the second grasping piece, an actuation state of the energy treatment instrument is switched between a first mode to coagulate a blood vessel of a circulatory system, and a second mode to coagulate a blood vessel of a pulmonary circulation in contrast to the first mode.
