Abstract

A treatment system that applies energy to a living tissue to treat the same, the treatment system includes a sealing member which joins desired sealed regions of at least two living tissues when the energy is applied to the living tissues in a state where the desired regions are sealed, a maintaining member which maintains living tissues near the sealed regions in a contact state when the energy is applied to the living tissues in a state where the tissues near the regions sealed by the sealing member are in contact with each other, at least one first control section which controls an output of the energy that is applied to the sealing member, and at least one second control section which controls an output of the energy that is applied to the maintaining member.

Dependent claims

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.

a handle which is operated to relatively move at least one of the holding surfaces with respect to the other;
a first joining member provided without discontinuity on the holding surface surrounding the cutter guide groove and the joining member is configured to join a predetermined region of the at least two living tissues when one of a high frequency energy or thermal energy is applied to the desired sealed regions of the at least two living tissues;
a second joining member which is provided opposite to the cutter guide groove with respect to the first joining member on the holding surface and which second joining member is configured to discontinuously join the living tissues when one of the high frequency energy or the thermal energy is applied to the living tissues near the region joining by the first joining member when it is in a state of contact;
a first output circuit configured to switch supplying or non-supplying of one of the high frequency energy or the thermal energy to the first joining member depending on a first impedance of the living tissues obtained by supplying the high frequency energy or the thermal energy to the first joining member;
a second output circuit configured to switch supplying or non-supplying of one of the high frequency energy of the thermal energy to the second joining member depending on the second impedance of the living tissues obtained by supplying the high frequency energy or the thermal energy to the second joining member;
a control section which controls 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 the high frequency energy or the thermal energy from the first output circuit or the second output circuit;
at least one first control section which controls an output of energy that is applied to the first joining member;
and
at least one second control section which controls an output of energy that is applied to the second joining member.
