Abstract: A cover includes a cover body and a covering portion. The cover body can include an opening edge exposing a part of a distal structure portion, an annular portion surrounding a periphery of the distal structure portion, a proximal edge, a dividing portion provided in the annular portion in a manner to define a slit that is continuous with the opening edge portion and the proximal edge portion, and an overlapping portion. The dividing portion includes a first cylindrical wall portion, and a second cylindrical wall portion. The first cylindrical wall portion and the second cylindrical wall portion overlap at least partly in the overlapping portion. The covering portion is configured to cover a part, where at least the dividing portion is provided.

Abstract: A distal-end cover is attached to a distal frame portion of an insertion portion of an endoscope main body, along a longitudinal axis of the insertion portion. The distal-end cover includes a cover main body attached to the distal frame portion and a wall provided on the cover main body. The wall is provided between a tube and a raising portion closer to the distal-end side along the longitudinal axis than a first opening edge portion of the distal frame portion when the cover main body is attached to an outside of the distal frame portion along the longitudinal axis of the insertion portion. The wall is deformed by the tube and an elongated member when the cover main body is removed from the outside of the distal frame portion.

Abstract: An endoscope includes a base, an operating portion, an elongated member, and a tube. The elongated member is inserted into the tube. The tube is elastically deformable between the one end and the other end of the tube. A side of closer to the one end of the tube is more compressively deformable along a longitudinal axis of the tube than a side closer to the other end of the tube.

Abstract: An endoscope cover includes a cover main body, a fragile portion, and a buffer portion. The cover main body includes a window and an annular portion. The window opens in a radial direction of a longitudinal axis of an insertion section. The annular portion is provided on a proximal side of the window along the longitudinal axis of the insertion section and surrounding the distal framing portion. The fragile portion is provided at a position on the annular portion which is adjacent to the window. The buffer portion is provided on the cover main body. The buffer portion includes an end portion. The end portion of the buffer portion is configured to reduce a force exerted from the distal side of the fragile portion onto the fragile portion along the longitudinal axis.

Abstract: The insertion device is adapted to hold a high-frequency treatment tool for performing high-frequency current treatment, by means of a distal-end component of a flexible tube for insertion into lumens. The insertion device includes: a first indicator disposed on the front portion of the distal-end component; a first cover formed of an insulating elasto-plastic material and covering the first indicator at the time of the prescribed attachment; an electrical insulation part as a second indicator disposed at the joint portion between the distal-end component and the flexible tube; and a second cover closely contacting the first cover and the electrical insulation part to apply an elastic force to each of them and covering the second indicator at the time of the prescribed attachment so that the leakage of high-frequency currents is prevented.

Abstract: An endoscope cover includes: a cylindrical cover main body that is to be attached to a distal framing portion along a longitudinal axis of an insertion section, and that includes an annular portion which is to cover part of an outer periphery of the distal framing portion; and a fragile portion, at least part of which is provided on the annular portion of the cover main body. The cover main body is spaced apart from at least part of the distal framing portion, and forms a gap between the cover main body and the distal framing portion. The fragile portion is broken under application of an intended stress and configured to have a user recognize breakage of the fragile portion in cooperation with the gap.
