Abstract:
A puncture needle for an endoscope includes a flexible sheath having a longitudinal axis and deformed to be bent by a raising base, a flexible needle tube having a needle tip and a distal opening section and that is movable in the sheath with respect to the sheath, and a stylet having a distal end surface that is able to advance and retreat in the needle tube and protrude and withdraw from needle tube along the longitudinal axis of the sheath, wherein the stylet retracts the needle tip such that the needle tip of the needle tube is separated from an inner surface of the sheath as the distal end surface of the stylet comes in contact with the inner surface of the sheath formed in the bent shape.
