## 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.

## Claims

### Claim 1

A treatment device for use with body tissue, the treatment device comprising:
an ultrasonic transducer configured to generate ultrasonic vibration;
a probe configured to transmit the ultrasonic vibration and a high-frequency current;
a treatment section at a distal end of the probe, the treatment section having a first treatment surface and a second treatment surface, and the treatment section being configured to treat the body tissue with the ultrasonic vibration and the high-frequency current that is transmitted to the first treatment surface and the second treatment surface via the probe,
the second treatment surface including:
a plain portion opposed to the first treatment surface,
a concave portion adjacent to the plain portion in a distal end direction, the concave portion being concave towards the first treatment surface and forming a profile of cylinder extending in a direction intersecting a longitudinal direction of the probe, and
an edge portion adjacent to the concave portion in the distal end direction and being exposed to allow the high-frequency current to electrically flow;
an electrically-insulating coating portion covering the plain portion and the concave portion of the second treatment surface; and
an outer peripheral portion corresponding 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 such that the body tissue is treated with the high-frequency current, wherein
the concave portion has a half-cylinder shape extending in a direction intersecting a longitudinal axis of a probe main body of the probe.

### Claim 2 (depends on 1)

The treatment device of claim 1, further comprising:
a neck portion provided between a probe main body 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, wherein
the electrically-insulating coating portion covers the neck portion and the probe main body.

### Claim 3 (depends on 1)

The treatment device of claim 1, wherein the electrically-insulating coating portion covers at least a part of the outer peripheral portion.

### Claim 4 (depends on 1)

The treatment device of claim 1, wherein the electrically-insulating coating portion covers the first treatment surface.

### Claim 5 (depends on 1)

The treatment device of claim 1, wherein the treatment section is shaped like a spoon or spatula.

### Claim 6 (depends on 1)

The treatment device of claim 1, wherein the edge portion is elevated from the concave portion of the second treatment surface in a direction away from the first treatment surface.

### Claim 7

A treatment device comprising:
an ultrasonic transducer configured to generate ultrasonic vibration;
a probe configured to transmit ultrasonic vibration and a high-frequency current;
a treatment section having: (A) a first treatment surface provided at a distal end of the probe, and (B) a second treatment surface, the treatment section being configured to treat the body tissue with the ultrasonic vibration and the high-frequency current that is transmitted 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,
the second treatment surface including:
a plain portion opposed to the first treatment surface,
a concave portion adjacent to the plain portion in a distal end direction, the concave portion being concave towards the first treatment surface and forming a profile of cylinder extending in a direction intersecting a longitudinal direction of the probe, and
an edge portion adjacent to the concave portion in the distal end direction and being exposed to allow the high-frequency current to electrically flow;
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;
an electrically-insulating coating portion covering the first treatment surface and the plain portion and the concave portion of the second treatment surface as well as the neck portion and the probe main body; and
an outer peripheral portion forming a side surface of the treatment section between the first treatment surface and the second treatment surface, the outer peripheral portion being exposed to allow high-frequency current to electrically flow to the body tissue such that the body tissue is treated with the high-frequency current, wherein
the concave portion has a half-cylinder shape extending in a direction intersecting a longitudinal axis of a probe main body of the probe.

### Claim 8 (depends on 7)

The treatment device of claim 7, wherein the edge portion is elevated from the concave portion of the second treatment surface in a direction away from the first treatment surface.
