Abstract: A treatment system includes a treatment tool having a heater and bipolar electrodes to grip a treatment target. 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 through a first circuit. A high-frequency current flows through the treatment target between the bipolar electrodes. The energy output source is configured to output heater electric power to the heater for generating heat through a second circuit. At least one processor is used to control the energy output source.

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 control device controls a surgical instrument including a heater. The control device includes a first power supply, a second power supply, a resistance value calculation section, and an output control circuit. The first power supply outputs a first current having a first frequency and supplied to the heater. The second power supply outputs a second current combined with the first current, supplied to the heater and having a second frequency different from the first frequency. The resistance value calculation section separates a signal component related to the second current from the first and second currents having passed through the heater, and calculates a heater resistance value based on the signal component. The output control circuit controls a temperature of the heater based on the heater resistance value.

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.
