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, if Figure 7 As shown, the 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 conne...

Abstract

The endoscope of the present invention has a front end hard part on which an endoscope observation mechanism is installed so that the front end hard part faces a desired direction, and a corner is provided on the base end side of the front end hard part. The mirror is characterized by inserting and attaching a flexure portion that bends following the load when a load equal to or greater than a predetermined set value acts between the distal end hard portion and the corner portion. Also, the endoscope of the present invention has: an insertion portion, a front end hard portion on which an endoscope observation mechanism is installed at the front end, a corner portion is provided on the base end side of the front end hard portion, and a A flexible part; a main body operating part, which is connected to the base end of the flexible part of the insertion part. The endoscope is characterized in that a length dimension ratio of the The corner portion is short and flexible in a bending direction, and a flexure operating mechanism for bending and operating the flexure portion is provided on the main body operation portion.

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 an angle 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...
