Abstract: An endoscope insertion shape observation apparatus has a processor configured to detect an insertion shape of an insertion portion inserted into a subject P, and calculate operation information, including one of easy insertion information or difficult insertion information, of insertion operation obtained in operation of inserting the insertion portion. The operation information is determined based on an insertion length of the insertion portion. The processor is also configured to simultaneously display of a result of the generation and the insertion shape on the monitor, and change between the easy insertion information and the difficult insertion information.

Abstract: Maximum hardness of a flexible tube section of an endoscope is set such that substantial maximum hardness at a time when an over-tube is attached is equal to or lower than maximum hardness of a flexible tube section of an endoscope. That is, the maximum hardness of the flexible tube section of the endoscope is set substantially equal to hardness obtained by subtracting hardness of the over-tube itself from the maximum hardness of the flexible tube section of the endoscope. In the endoscopes including a hardness changing function, maximum hardness of the endoscope, to which the over-tube is not attached, and maximum hardness of the endoscope, to which the over-tube is attached, are set substantially equal.

Abstract: An endoscope insertion observation apparatus includes a processor designed to perform functions including: detecting an insertion state of an insertion portion of an endoscope that is insertable into and extractable from a subject; determining whether or not the insertion portion has reached a second site in the subject from a first site in the subject and/or whether the insertion portion has reached the first site from the second site in the subject based on a detection result of the insertion state; and calculating a duration of movement of the insertion portion from the first site to the second site after determining that the insertion portion has reached the second site, or a duration of movement of the insertion portion from the second site to the first site after determining that the insertion portion has reached the first site.

Abstract: An endoscope system sets a hardness variation of a thick flexible tube portion and a hardness variation of a thin flexible tube portion such that their respective ratios against base hardness are constant, and as each flexible tube portion becomes thicker, the hardness variation increases and an endoscope with a relatively thin flexible tube portion has a smaller hardness variation. This makes it possible to avoid situations like an endoscope with a thick flexible tube portion lacking hardness or an endoscope with a thin flexible tube portion becoming too hard, and makes it possible to perform optimum insertion operation in accordance with the thickness of a flexible tube.

Abstract: An endoscope includes an objective optical system provided in a distal end portion of an insertion portion, and a light splitting element configured to split a light beam from an objective optical system into a plurality of light beams including a first light beam and a second light beam. The first light beam is reflected by a reflection mirror, and is formed into an image on a first image pickup device. The second light beam is formed into an image on a second image pickup device. The first image pickup device and the second image pickup device are disposed adjacent to the light splitting element at positions different from each other with respect to an optical axis of the light beam from the objective optical system.
