Abstract: An endoscope treatment tool includes: a sheath; a clip unit; a biasing member arranged between a distal end part of the sheath and the clip unit; and a first rotation preventing part capable of preventing the clip unit from rotating relative to the distal end part of the sheath about a longitudinal axis. The clip unit includes: a clip body; a holding tube; and a second rotation preventing part capable of preventing the clip body from rotating relative to the holding tubes about the longitudinal axis. The biasing member biases the holding tube so as to separate from the distal end part of the sheath. When a proximal end part of the holding tube comes into contact with the distal end part of the sheath against the biasing force of the biasing member, the first rotation preventing part prevents the relative rotation of the clip unit.

Abstract: A biopsy system includes an endoscope which includes an insertion portion having a channel, and a bendable portion provided in a distal end portion of the insertion portion; a needle tube which includes a distal end region, and a proximal end region having a higher bending rigidity than that of the distal end region; a sheath which can be inserted into the channel and inserted through by the needle tube; an attachment adapter which is provided on a proximal end side of the sheath and is capable of being mounted at the endoscope; and a connection member which connects the distal end region and the proximal end region, wherein the connection member can move within only a range of the insertion portion more proximal than a proximal end of the bendable portion and more distal than a proximal end of a follow-bending region.

Abstract: In a puncture needle for an endoscope, in a state in which a distal end of an outer sheath is located in an observation field of an observation optical system of an endoscope and a needle slider is retracted to abut a needle slider engaging section, a distal end of an inner sheath is located closer to a distal side than a proximal end of a raising base in the outer sheath, and a proximal end of the inner sheath is located closer to a proximal side than a needle tip of a needle tube in the outer sheath.
