Abstract: An endoscope of the disclosure includes an insertion section including a distal end portion, a bending portion, and a flexible tube portion. The distal end portion includes: a first opening connected to an instrument channel, a second opening connected to a wire channel, a wire, a first detent surface, and a raising base rotatable about an axis between a lowered position and a raised position. The raising base includes an attachment housing and a distal end of the wire is attached to the raising base at the attachment housing. The wire is movable within the wire channel to rotate the raising base about the axis from the lowered position to the raised position, and in the raised position, a stop surface of the attachment housing contacts the first detent surface to limit an amount of rotation of the raising base.

Abstract: A medical system including an endoscope configured to electrically drive an endoscopic operation. The endoscopic operation includes at least one of a forward and backward movement of an insertion section, a bending angle of a bending section of the insertion section, and a rolling rotation of the insertion section, the endoscope being configured to capture an endoscope image. The medical system further includes a processor comprising hardware. The processor is configured to control the endoscopic operation to achieve a second positioning subsequent to a first positioning, the first positioning being where the insertion section is positioned with respect to a papillary portion of a duodenum, the second positioning positions a distal end section of the insertion section with respect to a papillary portion of the duodenum based on the endoscope image.

Abstract: An inserting apparatus of the present invention includes a base provided in an insertion section, a first recess provided in the base, an opening forming surface formed around the first recess, a movable member configured to move in the first recess, a tabular lid member configured to close an opening of the first recess, a second recess provided in the lid member, a wall surface provided on the base, and opposed to at least a part of a side surface of the lid member in a state in which the contact surface is in contact with the opening forming surface, a fixing resin fixing the lid member to the base, and one or a plurality of protrusions provided on the side surface, having thickness smaller than thickness in the side surface of the lid member, and projecting toward the wall surface.

Abstract: An inserting apparatus includes a base, a first recess, an opening forming surface, a movable member, a tabular lid member including a contact surface, the lid member closing an opening of the first recess, a second recess provided on the contact surface of the lid member, fixing resin for fixing the lid member to the base, and a third recess being a cutout recessed from a sidewall of at least one of the first recess and the second recess along a boundary between the opening fanning surface and the contact surface and including, on an inner surface, the boundary between the opening forming surface and the contact surface. The opening arming surface of the base and the contact surface of the second recess are provided at least on one side of both ends defining a moving range, the moving range being a range in which the movable member moves.
