Treatment system, treatment instrument, and method for treating living tissue by use of energy

摘要

A treatment system includes a seal member, a maintaining member and a control section, and is configured to exert energy to a living tissue to treat the living tissue. The seal member is configured to join a sealed region which seals desirable regions of at least two living tissues when the energy is exerted to the sealed region. The maintaining member is configured to maintain the living tissues in the vicinity of the sealed region being brought into contact with each other when the energy is exerted to the living tissues. The control section is configured to offset energy output timings of the seal member and the maintaining member.

主权项

1. A treatment system configured to exert energy on at least two living tissues to treat the living tissues, comprising:
first and second holding members configured to hold the living tissues, each including a holding face opposed to each other, and also including a distal end and a proximal end, the two ends defining a longitudinal direction; a cutter guide groove formed in at least one of the first and second holding members and configured to guide a cutter from the proximal end to the distal end; a seal member disposed on the holding face of the first holding member, surrounding the cutter guide groove, and configured to seal the living tissues and form a sealed region in the living tissues when the energy is exerted on the sealed region through the seal member; maintaining members disposed on the holding face of the first holding member between an outer edge of the holding face of the first holding member and the seal member and configured to exert energy on an outer periphery of the sealed region; and a control section configured to offset energy output timings of the seal member and the maintaining members, wherein: each of the maintaining members has conductive properties and is formed into a circular shape and the maintaining members are aligned in parallel with the longitudinal direction, electrically insulated from each other, physically isolated from each other, and configured to discretely join the living tissues together her by the energy exerted through the maintaining members and maintain a contact state between the living tissues.
