1. A medical instrument comprising:
a first elongated member including:
a fluid lumen through which a fluid is flowable,
a fluid supply section through which fluid is suppliable to the fluid lumen, and
an aperture opening located in a distal end surface of the first elongated member, the aperture being configured to allow fluid to exit the fluid lumen via the aperture;
a second elongated member including:
an insertion lumen in which the first elongated member is insertable, and
a discharge section through which the fluid can be discharged; and
a movement section comprising a seal member configured to form a seal between the first elongated member and the second elongated member in a state where the first elongated member is disposed in the insertion lumen of the second elongated member, the movement section being configured to allow the first elongated member and the second elongated member to move relative to each other such that the discharge section of the second elongated member is positionable on a distal side of the aperture of the first elongated member,
wherein the first elongated member is more rigid than the second elongated member, and
wherein the movement section includes an expandable and contractible bellows-like expansion-and-contraction part formed at least at a part of the second elongated member.
