Abstract

A control member (90) for restricting expansion caused by a change in internal pressure of the external cover (75) is provided to a control lever type (joystick type) endoscope (1) having an operating rod (45) and an external cover (75). ), wherein the operating lever (45) can adjust the bending angle of the bending portion (7) in conjunction with the tilting action of the operating portion (3), and the outer peripheral edge portion of the exterior cover (75) is watertightly fixed to the operating portion main body (32) (operating portion (3)) and the inner peripheral portion covers the outer periphery of the operating rod (45) watertightly, and can be changed according to the pressure inside the operating portion (3) (that is, formed inside the endoscope (1) The pressure fluctuation of the confined space (15)) deforms.

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 the medical and industrial fields to observe inside of a living body, inside a structure, or other places where observation of the inside of a subject is difficult. [0003] The insertion portion of such an endoscope is provided with a curved portion for improving insertion and observation into the subject. The bending portion is bent by a bending operating device provided in the operating portion. [0004] As a bending operation device, a joystick-type device that performs a bending operation on a bending portion by tilting an operation lever is widely known. In the joystick type bending operation device, in order to allow the tilting operation of the bending rod protruding outside t...
