Abstract: A method of operating a power source device for a high-frequency treatment instrument adapted to perform high-frequency treatment for biological tissue includes causing a high-frequency power source circuit to output power; setting a target impedance value which gradually increases from a change-over impedance value to a stop impedance value; regularly comparing a measured impedance value to the target impedance value; causing the high-frequency power source circuit to lower the power by a first ratio if the measured impedance value is greater than the target impedance value, and to raise the power by a second ratio if the measured impedance value is smaller than the target impedance value; and causing the high-frequency power source circuit to terminate the output upon the value for impedance reaching the stop impedance value.

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.

Abstract: A treatment system includes a treatment tool and an energy source apparatus used to supply electrical energy to the treatment tool. The treatment tool includes a heater and bipolar electrodes to grip a treatment target. The energy source apparatus includes a processor to control the output to the bipolar electrodes and the heater, respectively. The processor directs the output to the bipolar electrodes and detects an initial value of the impedance of the treatment target. The processor determines whether or not the impedance has reached a minimum value and then retrieves a parameter that is detected before the minimum value of the impedance is detected. The processor performs a first process and/or a second process based on the acquired parameter after the minimum value is detected. The first process determines whether or not the output to the heater is required. The second process sets a target value.
