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.

Abstract: A heating treatment apparatus to treat a living tissue by heating the living tissue includes a first holding member and a second holding member, a first heat generating element provided on the first holding member, a second heat generating element provided on the second holding member, a power supply unit supplying electric power to cause the first heat generating element and the second heat generating element to generate heat, and a control unit controlling operations of the power supply unit. The control unit switches a mode between a first mode and a second mode during treatment of the living tissue. Temperatures of the first heat generating element and the second heat generating element are controlled to the same temperature in the first mode and to different temperatures in the second mode.
