Abstract

An ultrasonic treatment apparatus includes a sheath which has an opening at a distal-end thereof; an ultrasonic transducer which is connected to the sheath, the ultrasonic transducer being able to generate ultrasonic vibration which is of treatment energy; an ultrasonic power supply unit which supplies electric power for driving the ultrasonic transducer; a treatment unit which is connected to the ultrasonic transducer, the treatment unit transmitting the ultrasonic vibration to a living tissue; and a high-frequency power supply unit which supplies high-frequency current which is of the treatment energy to the treatment unit.

Claims

1. A treatment method comprising:

an insertion process of inserting an insertion unit of an endoscope apparatus into a subject, the endoscope apparatus including;

an ultrasonic treatment apparatus including;

a sheath which has an opening at a distal end thereof,

an ultrasonic transducer which is connected to the sheath, the ultrasonic transducer being able to generate ultrasonic vibration which is of treatment energy,

an ultrasonic power supply unit which supplies electric power for driving the ultrasonic transducer,

a treatment unit which is connected to the ultrasonic transducer, the treatment unit transmitting the ultrasonic vibration to a living tissue, and

a flat plate which extends substantially parallel to the treatment unit with a predetermined clearance therebetween;

the flexible insertion unit in which the sheath can be arranged; and

an observation unit which is provided inside the insertion unit, the observation unit being able to observe an outside from a distal end of the insertion unit;

an arrangement process of arranging a treated site of a subject in a visual field of the observation unit;

a marking process of performing marking of surrounding tissue of the treated site;

an injection process of injecting a local injection solution into a lower portion of the treated site through an inside channel of the insertion unit;

an incision and dissection process of incising and dissecting a living tissue including the treated site with the ultrasonic treatment apparatus, the living tissue being raised by the injection of the local injection solution; and

a hemostatic process of performing hemostasis with the ultrasonic treatment apparatus when bleeding is generated in the incision and dissection process,

wherein the incision and dissection process includes sandwiching the living tissue between the treatment unit and the flat plate, applying ultrasonic vibration, and twisting the treatment unit in a circumferential direction.

2. The treatment method according to claim 1, wherein in the marking process, a high-frequency current which is of the treatment energy is supplied to the treatment unit, and the marking is performed with the treatment unit.

3. The treatment method according to claim 1, wherein in the incision and dissection process, the incision and the dissection are performed using at least one method of a method of transmitting the ultrasonic vibration which is of the treatment energy from the treatment unit to the living tissue including the treated site and a method of supplying the high-frequency current which is of the treatment energy to the treatment unit.

4. A treatment method comprising:

an insertion process of inserting an insertion unit of an endoscope apparatus into a subject, the endoscope apparatus including;

an ultrasonic treatment apparatus including;

a sheath which has an opening at a distal end thereof,

an ultrasonic transducer which is connected to the sheath, the ultrasonic transducer being able to generate ultrasonic vibration which is of treatment energy,

a treatment unit which is connected to the ultrasonic transducer, the treatment unit transmitting the ultrasonic vibration to a living tissue, and

a flat plate which extends substantially parallel to the treatment unit with a predetermined clearance there between;

the flexible insertion unit in which the sheath can be arranged; and

an observation unit which is provided inside the insertion unit, the observation unit being able to observe an outside from a distal end of the insertion unit;

an arrangement process of arranging a treated site of a subject in a visual field of the observation unit;

a marking process of performing marking of surrounding tissue of the treated site;

an injection process of injecting a local injection solution into a lower portion of the treated site through an inside channel of the insertion unit;

an incision and dissection process of incising and dissecting the living tissue including the treated site with the ultrasonic treatment apparatus, the living tissue being raised by the injection of the local injection solution; and

a hemostatic process of performing hemostasis with the ultrasonic treatment apparatus when bleeding is generated in the incision and dissection process,

wherein the incision and dissection process includes sandwiching the living tissue between the treatment unit and flat plate, applying ultrasonic vibration, and twisting the treatment unit in a circumferential direction.
