Patent ID: 8500736

Claim:
A treatment method for a living tissue using energy, comprising: a first step of holding the living tissue between a pair of holding members; a second step of applying high-frequency energy from a high-frequency output portion of the holding members to the living tissue held between the holding members, destroying cell membranes of cells in the living tissue, causing proteins to flow out of the cells and dehydrating the living tissue; a third step of detecting biological information, indicating a state of dehydration of the living tissue, with a detector; and a fourth step of transmitting and applying heat energy from a surface of a heat generation portion of the holding members to the living tissue, and dehydrating the living tissue, wherein a heat, generated from the heat generation portion including a plurality of discrete heater members arranged on a back surface of the high-frequency output portion and not in contact with the living tissue, is able to be conducted to the high-frequency output portion and the living tissue when the living tissue is held between the holding members wherein the method comprises: setting a setting value, including at least one of the temperature and a time in regard to the heat generation portion, by a setting portion; and controlling, by a control section, the high-frequency output portion to apply the high-frequency energy in order to dehydrate the living tissue and then stop applying the high-frequency energy and thereafter controlling, by the control section, the heat generation portion to apply the heat energy to the living tissue, in accordance with a detection result from the detector, so that the living tissue dehydrated by the high-frequency energy is further dehydrated by the heat energy and then stop applying the heat energy, based on the setting value set by the setting portion.
