Abstract: Provided is an endoscope capable of operating a bending part with a higher degree of freedom while enabling a related-art operation of moving a pair of bending operating wires forward and backward. The endoscope has an insertion part having a bendable bending part; an operating part continuously provided on a proximal end side of the insertion part; a pair of bending operating wires inserted into the insertion part and fixed to a distal end side of the insertion part; a first bending operating mechanism that operates the bending part by moving the pair of bending operating wires forward and backward in conjunction with each other; and a second bending operating mechanism that operates the bending part by independently moving the pair of bending operating wires forward and backward.

Abstract: Provided is an endoscope allowing two operating methods, that is, a surgeon's own manual operation and an operating method using a hand other than the surgeon regarding a hardness adjusting operation. An endoscope includes an insertion part having a flexible part; an operating part continuously provided on a proximal end side of the insertion part; a hardness adjusting mechanism serving as a first driving force input member that is provided from the operating part to the flexible part and adjusts the hardness of the flexible part; an operating ring that is provided in the operating part and is manually operated and inputs a driving force to the hardness adjusting mechanism; and a shaft serving as a second driving force input member that is provided separately from the operating ring and inputs a driving force to the hardness adjusting mechanism.

Abstract: An endoscope includes a first flat surface formed at a distal end portion of an insertion part to be inserted into a subject, and orthogonal to an axial direction of the insertion part, an observation window provided at the distal end portion for allowing image light of the subject to be taken therethrough, with a surface of the observation window as a light incidence plane, a forceps outlet disposed on the first flat surface, a first illumination window provided at the distal end portion to irradiate a subject with illumination light, a second illumination window provided at the distal end portion to irradiate the subject with illumination light, a fluid jetting nozzle arranged at the first flat surface to jet a fluid toward the observation window and fixed at the distal end portion of the insertion part, and an inclined surface formed around the observation window.

Abstract: There is provided a bending portion for an endoscope and the endoscope which can prevent the piece fall of bending pieces without enlarging the diameter of the bending portion and raising the filling rate of built-in components in the bending portion. In the bending portion, one bending piece of adjacent bending pieces is formed so that a cross-sectional shape is, for example, an elliptic shape whose major axis direction or minor axis direction corresponds to a first direction. The other bending piece of the adjacent bending pieces is formed so that a cross-sectional shape is, for example, a circular shape in which a length in the first direction differs from the first bending piece; and an abutting portion in which their end portions facing each other of the adjacent bending pieces abut on each other in at least two points when the bending portion is bent.
