Abstract: Operability in inserting an insertion part of an endoscope into a body cavity using an insertion assisting tool is improved. In an insertion assisting tool, a sidewall portion of a tube main body through which an insertion part of an endoscope is passed is provided with a sidewall opening part having a size in which the insertion part can pass through. A distal end side of the sidewall opening part is provided with a guiding valve, and the insertion part is guided by the guiding valve to be easily fed from the sidewall opening part. The guiding valve is swingably supported, and when the insertion part is fed from a distal end opening part of the tube main body, allowing the parallel state of being substantially parallel to an axial direction of the insertion part and passing the insertion part to a distal end opening part side are enabled.

Abstract: Operability in inserting an insertion part of an endoscope into a body cavity using an insertion assisting tool is improved. In an insertion assisting tool 60, a sidewall portion of a tube main body 64 through which an insertion part 12 of an endoscope 10 is passed is provided with a sidewall opening part 68 having a size in which the insertion part 12 can pass through. A distal end side of the sidewall opening part 68 is provided with a guiding valve 82, and the insertion part 12 is guided by the guiding valve 82 to be easily fed from the sidewall opening part 68. The guiding valve 82 is swingably supported, and when the insertion part 12 is fed from a distal end opening part 67 of the tube main body 64, allowing the parallel state of being substantially parallel to an axial direction of the insertion part 12 and passing the insertion part 12 to a distal end opening part 67 side are enabled.

Abstract: An endoscope system includes: an endoscope including a side-viewing observation unit that includes a field of view in a lateral direction of an insertion part to be inserted into an object to be observed and a second protruding portion that protrudes from the insertion part and forms a blind spot in the field of view of the side-viewing observation unit; an image acquisition unit that acquires a side-viewing observation image by using the side-viewing observation unit; a monitor that displays the side-viewing observation image; and a display control section that allows at least a part of the blind spot of the side-viewing observation image in which the second protruding portion is shown up not to be displayed, and displays the side-viewing observation image on the monitor.
