Abstract
A treatment device includes, a probe that conveys ultrasonic vibration and a high-frequency current; a treatment section that comprises a first treatment surface provided at a distal end of the probe for treating body tissue and a second treatment surface opposed to the first treatment surface, and treats the 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; and an electrically-insulating coating portion that covers at least one of the first treatment surface and the second treatment surface.
Claims12
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.

A treatment device comprising:
- a probe that conveys ultrasonic vibration and a high-frequency current;
- a treatment section that comprises a first treatment surface provided at a distal end of the probe for treating body tissue and a second treatment surface opposed to the first treatment surface, and treats the 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, the first treatment surface and the second treatment surface being plates opposed to each other;
- and
- 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;
- a neck portion provided between a probe main body of the probe and the treatment section and having a dimension smaller than that of the treatment section with respect to a width direction intersecting a longitudinal axis of the probe main body;
- and
- an electrically-insulating coating portion that covers at least one of the first treatment surface and the second treatment surface as well as the neck portion and the probe main body.
