Abstract: An endoscope includes: an objective optical system including a lens, allowing light from an imaging subject to be incident on a distal end surface, and focusing the light onto an image-capturing surface of an image-capturing element; an elongated light guide provided adjacent to a side of the system and guiding illumination light to be emitted from a distal end; and an optically transparent distal end cover disposed at a position where the distal end of the guide is covered, wherein the distal end surface is located farther forward than the distal end of the guide, a notched portion is provided at a distal-end outer edge of a side surface of the system, the side surface being adjacent to the guide, so that the system is narrower toward a front side from the distal end of the guide, and the cover is provided so as to bulge toward the notched portion.

Abstract: An endoscope includes a distal end portion in which an optical unit and a treatment instrument channel are held such that a photographing optical axis, a central axis of the distal end portion, and a central axis of the treatment instrument channel are linearly aligned When viewed from an end face of the distal end portion. The first magnet and the second magnet are arranged at non-rotationally-symmetric positions with respect to the photographing optical axis, and a region of the optical unit, which is on a side where a distance between the first magnet and the second magnet on an arc of a circle around the photographing optical axis is short, faces the treatment instrument channel.

Abstract: The disclosed technology is directed to an endoscopic apparatus comprises an endoscope having a cable connected to an electronic circuit part of the endoscope. The cable includes an elongated covering and an elongated component configured to be concentrically engaged with the elongated covering. A securing member is used to bind and to secure the elongated covering and the elongated component to one another. The elongated covering includes at least one recess formed on an outer circumferential area of the elongated covering on which the securing member binds and secures the elongated covering. The securing member has a portion that sinks in the at least one recess and secures the elongated covering and the elongated component that is exposed through the at least one recess.

Abstract: An endoscope includes a first breakable portion provided between a part of an outer peripheral surface of a distal rigid section main body and a second inner peripheral surface, and including a fragile portion which is formed in a concaved-shape and which is more easy to break than any other part of the outer peripheral surface except for thereof. The endoscope includes a second breakable portion provided between a first inner peripheral surface and the second inner peripheral surface, and a third breakable portion provided between the first inner peripheral surface and a part of the outer peripheral surface of the distal rigid section main body, which differs from the fragile portion.
Abstract translation: 一种内窥镜，包括设置在前端刚性部分主体的外周面的一部分与第二内周面之间的第一可破坏部，并且包括形成为凹形且容易断裂的脆弱部 除外的外周表面的任何其他部分。 内窥镜包括设置在第一内周面和第二内周面之间的第二可破坏部，以及设置在第一内周面与远侧刚性部主体的外周面的一部分之间的第三可破坏部， 不同于脆弱部分。
