Embodiment Construction

[0031] The present invention will be described with reference to the accompanying drawings.

[0032] Each drawing used in the following description is schematically shown, and in order to show each constituent element to the extent that it can be recognized on the drawing, the dimensional relationship and scale of each member may be different for each constituent element. And show it. Therefore, the present invention is not limited to the illustrated form with respect to the number of constituent elements, the shape of the constituent elements, the ratio of the size of the constituent elements, and the relative positional relationship of the respective constituent elements.

[0033] figure 1 The endoscope 1 shown is, for example, an endoscope used in urology.

[0034] The endoscope 1 has an operation part 3 and an elongated insertion part 2 which is inserted into a subject.

[0035] The insertion part 2 is comprised so that the front-end|tip part 2a, the bending part 2b, an...

Abstract

This endoscope 1 includes: an insertion portion 2 that has a bending portion 2b; a manipulable portion 3 that has holding portions 4,5 and a manipulable portion body 6; a pedestal portion 6a that protrudes from the manipulable portion body 6; an axial member 7a that is tilt-operated by a finger of a hand of an operator that holds the holding portions 4,5; a finger-abutting portion 7b which is provided on an end of the axial member 7a and on which the finger of the hand that holds the holding portions 4,5 is placed; and stepped portions 30, 20 which are provided outside the periphery of the pedestal portion 6a and respectively on opposite sides of the axial member 7a from the holding portions 4,5 held by the operator, and on which fingers of the operator that holds the holding portions 4,5,other than the finger that is placed on a finger placing portion 7d, can be placed.

Description

technical field [0001] The present invention relates to an endoscope in which a bending operating lever is provided on an operating portion to perform a tilting operation when bending a bending portion. Background technique [0002] The endoscope has an elongated insertion portion, and an observation optical system is provided on the distal end side of the insertion portion. There are types of endoscopes that have a curved portion on the distal end side of the insertion portion, and the curved portion is configured to bend in two directions up and down or in four directions up, down, left, and right. In the endoscope, by providing a curved portion in the insertion portion, the insertion property into the subject can be improved, and the viewing direction can be changed to perform observation in a wide range. [0003] Usually, an operation part that also serves as a grip part is provided at a base end part of the insertion part. Furthermore, in an endoscope having a bending...
