Abstract: A treatment system comprises a treatment tool and an energy source apparatus is used to electrically communicate with the treatment tool. The energy output source is configured to output high-frequency electric power to the bipolar electrodes so as to cause a high-frequency current to flow through a treatment target between the bipolar electrodes. A processor is used to control the energy output source. The processor performs an output control process on the heater electric power so that the heater reaches a target temperature and maintains at the target temperature. The processor detects a parameter related to the heater from the heater in the output control process based on the target temperature. The processor sets a threshold value used to determine to stop or to lower the output to the bipolar electrodes while the treatment target is being modified by the high-frequency current applied thereto based on the detected parameter.

Abstract: A treatment system includes a treatment tool and an energy source apparatus. The treatment tool includes a heater and bipolar electrodes to grip a treatment target. The energy source apparatus supplies electrical energy to the treatment tool. A processor controls the output to the bipolar electrodes and the heater. The processor causes a high-frequency electric power to be output to the bipolar electrodes and detects a parameter that varies depending on tissue volume of the treatment target. The processor sets a target value related to an output control process for controlling the output to the heater. The processor controls the output to the heater so as to modify the treatment target with the heat of the heater. The processor increases the output and temperature to the heater until at least a predetermined point of time after starting the output control process for controlling the output to the heater.

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.
