A submucosal layer dissection instrument of the present invention includes an instrument body that is inserted into a submucosal layer, a line formed between the proximal end side and the distal end side of the instrument body; and an expanding section provided on the distal end side of the instrument body that expands in the case of having received a supply of fluid through the line.

Submucosal layer dissection instrument, submucosal layer dissection system, and submucosal layer dissection method

This mucosa separation apparatus includes a first insertion portion inserted to the interior of a subject, an expansion portion disposed on a head portion of the first insertion portion, and which expands by infusion of a fluid, a passage formed within the first insertion portion and connected to the expansion portion, for supplying the fluid to the expansion portion, and a curving portion which makes a head portion of an instrument inserted to the interior of the subject curve with respect to a part of the instrument which is closer to a base portion of the instrument than the head portion thereof.

Mucosa separation apparatus, and method for mucosa separation

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.
