Abstract
An assist tool attachable to an insertion section of an insertion apparatus includes a tube including a longitudinal axis. The tube is provided with a lumen through which the insertion section is insertable. The tool includes a connecting mechanism. The connecting mechanism receives a drive force and is rotated together with the tube with respect to the insertion section inserted through the lumen. The tool includes a locking mechanism provided on a more distal end side than the connecting mechanism in the tube. The locking mechanism includes a convex portion or a concave portion engaged with the insertion section to restrict movement of the tube along the longitudinal axis with respect to the insertion section. Furthermore, an insertion apparatus to which the tool is attached and an introduction apparatus including them is provided.
