20160100746 | ENDOSCOPE, OVERTUBE, AND ENDOSCOPE SYSTEM - Provided is an endoscope including an inserted portion that has, sequentially from a distal-end side, a distal-end portion, a bending portion, and a flexible portion; a wire that has an exposed portion that is disposed outside the distal-end portion of the flexible portion along the longitudinal direction and whose positions, at a first position and a second position that is separated from the first position on the base-end side, are restrained with respect to the distal-end portion of the flexible portion in a radial direction; and a wire adjusting portion that changes the length between the first position and the second position of the wire. | 04-14-2016 |
