Abstract: An endoscope system includes an endoscope, and an insertion auxiliary tool into which the endoscope is inserted. A flexible portion of the insertion section of the endoscope includes, from a distal end side toward a proximal end side, a low flexural rigidity portion, a flexural rigidity varying portion in which a flexural rigidity increases from the distal end side toward the proximal end side, and a high flexural rigidity portion with flexural rigidity higher than that in the low flexural rigidity portion. When at least a part of the flexible portion projects from a distal end opening of the tube body, a position of the proximal end of the low flexural rigidity portion is positioned closer to a proximal end of the insertion auxiliary tool than the distal end opening of the tube body from the proximal end of the insertion auxiliary tool.

Abstract: A flexible tube for an endoscope includes a flexible tube base, an outer coating layer including a soft resin layer and a hard resin layer, a ratio changing portion, and a tapered portion. In the ratio changing portion, a percentage of a thickness of the hard resin layer decreases and a percentage of a thickness of the soft resin layer increases toward a distal side from a proximal side of the base. In the tapered portion, a ratio between the thickness of the hard resin layer and the thickness of the soft resin layer is maintained, which ratio is the same as that at a position in the ratio changing portion where the percentage of the thickness of the hard resin layer is a lower limit. In the tapered position, an outer diameter of the outer coating layer decreases toward a distal end of the flexible tube base.

Abstract: Provided is an overtube that can be easily gripped by the operator. The overtube includes a tube main body, a gripping cylinder connected to the proximal end side of the tube main body, a balloon mounted on an outer peripheral surface on a distal end side of the tube main body, and an air supply pipe line that is arranged to be parallel to an endoscope insertion passage from the tube main body to the gripping cylinder and communicates with the balloon. The gripping cylinder includes a first connecting pipe that extends obliquely outward from a first position of a gripping cylinder side portion toward the proximal end side of the gripping cylinder, and a second connecting pipe that extends obliquely outward from a second position different from the first position toward the proximal end side of the gripping cylinder. The gripping cylinder is an integrally molded body in which the first connecting pipe and the second connecting pipe are integrally molded. In a case where the plane orthogonal to the center axis of the gripping cylinder is defined as a first surface, and the plane orthogonal to the first surface and intersecting the air supply pipe line is defined as a second surface, the first position and the second position are disposed on the same side with respect to the reference surface orthogonal to the first surface and orthogonal to the second surface.
