Abstract:
1. A treatment system which is configured to apply energy to a living tissue to treat the living tissue, comprising: a pair of holding members, each having a holding surface configured to hold at least two living tissues; a cutter guide groove configured to guide and take a cutter to cut the living tissues inside and outside with respect to the holding face; a sealing member provided without discontinuity on the holding surface surrounding the cutter guide groove and configured to join desired regions of the at least two living tissues when one of a high frequency energy or thermal energy is applied; a maintaining member provided on the holding surface at a side opposite of the cutter guide groove with respect to the sealing member and which the maintaining member maintains joining by discontinuous joining the living tissues when one of the high frequency energy or thermal energy is applied to the living tissues near the region sealed by the sealing member when it is in a state of contact; a first output circuit which is configured to switch supplying or non-supplying of one of the high frequency energy or the thermal energy to the sealing member, depending on a first impedance of the living tissues, obtained with supplying one of the high frequency energy or the thermal energy to the sealing member; a second output circuit which is configured to switch supplying or non-supplying of one of the high frequency energy or the thermal energy to the maintaining member, depending on the second impedance of the living tissues, obtained with supplying the high frequency energy or the thermal energy to the maintaining member; a control section which is configured to control the first output circuit and the second output circuit, the control section comparatively determining the first impedance or the second impedance with a predetermined impedance and controlling the supply of one of the high frequency energy or the thermal energy from the first circuit or the second circuit output.
