Problems solved by technology

At this time, if the internal pressure is excessively increased, the stretched area of ​​the exterior cover may be deformed and folded.
[0008] Therefore, it is necessary to depressurize the inside of the endoscope after a manual leak test and then clean it with an automatic endoscope cleaning device that

Embodiment Construction

[0022] Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. In addition, in each of the drawings used in the following description, the scale is different for each constituent element so that each constituent element has a size that can be recognized on the drawings, and the present invention is not limited to the structures described in these drawings. The number of elements, the shape of structural elements, the ratio of the size of structural elements, and the relative positional relationship of each structural element. In addition, in the following description, the up-and-down direction when viewed in a drawing is sometimes described as the upper part and the lower part of the constituent elements.

[0023] First, an endoscope according to one embodiment of the present invention will be described below with reference to the drawings.

[0024] in addition, figure 1 is a front view showing the external structure of t...

Abstract

This endoscope (1) is provided with: an operation lever part (30) which is provided to an operation unit (3), which has an operation shaft (32), and which can adjust the curve angle of a curved section (7) in association with an inclination operation; a sliding body (37) which is disposed so as to freely advance/retract in the axial direction of the operation shaft (32); a flexible exterior cover(33) which is watertightly fixed to the operation unit (3) so as to cover the outer peripheries of the sliding body (37) and the operation shaft (32) and which can deform due to a change in the internal pressure of the operation unit (3); and a returning member (38) which causes the sliding body (37) to return to the operation unit (3) side when the internal pressure of the operation unit (3) is relieved.

Description

technical field [0001] The present invention relates to an endoscope that flexes a bending portion in conjunction with a tilting operation of an operation lever. Background technique [0002] Conventionally, endoscopes that can be inserted into a subject have been widely used, for example, in medical and industrial fields to observe difficult-to-observe internal parts of a subject, such as inside a living body and inside a structure. [0003] The insertion portion of such an endoscope is provided with a curved portion for improving insertion and observation into the subject. The bending operation of the bending portion is performed by a bending operation device provided on the operating portion. [0004] As a bending operation device, there is known a joystick-type device that performs a bending operation on a bending portion by tilting an operation lever as disclosed in, for example, Japanese Patent Application Laid-Open No. 2004-321612. [0005] In such a conventional jo...
