    摘要： The needle for an endoscope includes: a wire for driving a hollow needle accommodated in a tube and having a side hole so as to be protruded from the distal end of the tube and retracted thereinto; a ferrule member, attached to the proximal end of the tube, for supplying a fluid from the distal end of the hollow needle via the tube; a first fluid-tight member, provided at the distal end side from the side hole of the hollow needle, for keeping the outer circumferential surface of the hollow needle and the inner wall of the outer sheath tube fluid-tight; and a second fluid-tight member for keeping the inner wall of the ferrule portion and the wire fluid-tight, and further includes blocking device consisting of a sealing member provided at an intermediate part of the wire, and an orifice for opening and shutting off circulation of a fluid between the ferrule member, in which the sealing member is inserted, and the hollow needle in line with extension of the hollow needle from the distal end of the outer sheath tube and retraction of the same thereinto.

    摘要： An ultrasound probe includes a treatment portion that is formed at a distal end of a transmission portion transmitting input vibration energy, the treatment portion being configured to vibrate with a predetermined amplitude to cut a treatment target object, in which the treatment portion includes a first striking face that faces the treatment target object, a second striking face that faces the treatment target object at a position away from the first striking face toward a proximal end side in an axial direction, and a first side surface that connects the first striking face and the second striking face in the axial direction and that has a predetermined length in the axial direction, in which when the predetermined length of the first side surface is h, 0
