Abstract: An energy output section outputs first electric energy so that a high-frequency current flows between electrodes through a treated target, and outputs second electric energy so that heat occurs in an end effector. A controller outputs the first electric energy at the same time as the second electric energy in at least a part of a period during which the heat is continuously denaturing the treated target from an output start of the second electric energy. The controller makes, based on judging that the treated target entered a predetermined state, an electric power of the first electric energy increased.

Abstract: A treatment system includes a pair of holding members, a high-frequency energy output section, a heat generating section and a control section. At least one of the pair of holding members moves to the other holding member. The high-frequency energy output section and the heat generating section are provided on at least one of the holding members. The high-frequency energy output section exerts high-frequency energy to a living tissue to denature the living tissue, and collects the biological information of the living tissue. The heat generating section applies heat to it held between the holding members, generates the heat owing to the supply of the energy, and conducts the heat therefrom to denature the living tissue. The control section controls the output of the energy to the high-frequency energy output section and the heat generating section based on the biological information collected by the high-frequency energy output section.
