Embodiment Construction

[0043] Hereinafter, an embodiment of the present invention will be described based on the drawings. The configuration shown in this embodiment is that the insertion portion of the endoscope is inserted through the nasal cavity of the subject, and is used as upper digestive tracts such as the esophagus, stomach, and duodenum. However, the path of the insertion portion is not limited to this.

[0044] First, as shown in FIG. 7 , an endoscope 1 generally includes an insertion portion 2 , a main body operation portion 3 connected to the insertion portion 2 , and a universal cord 4 . The insertion part 2 is composed of a flexible part 2a bent in an arbitrary direction by a predetermined length from a connecting part connected to the main body operation part 3, and a front end part of the flexible part 2a is connected to a corner part 2b. The front end of the corner portion 2b is connected to the front end rigid portion 2c. In addition, the universal cord 4 is detachably connected...

Abstract

The invention easily advances following a bent insertion route without specially damaging a function as an angle part. A flexible part is provided between the proximal end part of an end part ring constituting a distal end hard part and the distal end ring of the angle part, wherein the flexible part is composed of a first joint ring body pivoted to the end part ring by a pivot pin and a second joint ring body pivoted to the distal end ring by a pivot pin. The pivot pins are respectively provided on two parts on both left and right side parts, the first joint ring body and the second joint ring body are pivoted by the pivot pins, and when bending force acts on the distal end hard part, the distal end hard part is bent vertically and horizontally at a prescribed angle around the respectivepivot pins.

Description

technical field [0001] The present invention relates to an endoscope in which a distal end hard portion is formed at the distal end of a corner portion, and more particularly relates to an insertion portion formed in a narrow-diameter structure capable of being inserted through a nose. [0002] In addition, the present invention relates to an endoscope having an insertion portion with a narrow structure suitable for insertion into a narrow path such as a path inserted through a nose. Background technique [0003] As an endoscope used for medical treatment, an insertion part inserted into a body cavity is provided by being connected to a main body operating part, and at least a universal cord (universal cord) detachably connected to a light source device is provided from the main body operating part. Extended and roughly constituted. The insertion part is composed of a flexible part that is bent in any direction along the insertion path from most of the length of the connect...
