1. A treatment device, comprising:
a probe that conveys ultrasonic vibration and a high-frequency current; a treatment section that is provided at a distal end of the probe, comprises a first treatment surface and a second treatment surface opposed to the first treatment surface and provided with a concave portion, and treats body tissue with the ultrasonic vibration and the high-frequency current conveyed to the first treatment surface and the second treatment surface via the probe; an edge portion exposed to allow the high-frequency current to electrically flow and provided separated from the concave portion; and an electrically-insulating coating portion that covers the second treatment surface except for the edge portion an outer peripheral portion that corresponds to a side surface of the treatment section positioned between the first treatment surface and the second treatment surface, is exposed to allow the high-frequency current to electrically flow to the body tissue, and treats the body tissue with the high-frequency current. |
