Problems solved by technology

That is, the outer diameter of the overlapping portion becomes large, or the fixation of the endoscope cover 2 or the endoscope balloon 1 is insufficient.
Moreover, since the endoscope cover 2 and the belt ring 5 interfere with each other, it is difficult to carry out the installation work of the endoscope cover 2 or the endoscope balloon 1.

Embodiment Construction

[0036] Hereinafter, best embodiments of an endoscope cover, an endoscope, and a method for fixing an endoscope balloon according to the present invention will be described in detail with reference to the drawings.

[0037] FIG. 1 is a diagram showing a system configuration of a double-balloon endoscope device to which the present invention is applied. As shown in FIG. 1 , the endoscope is mainly composed of an endoscope 10 , an insertion assisting device 70 , and a balloon control device 100 .

[0038] The endoscope 10 includes a hand operation unit 14 and an insertion unit 12 connected to the hand operation unit 14 and inserted into a body cavity. A universal cable 16 is connected to the handheld operation unit 14 , and an LG connector 18 is provided at the tip of the universal cable 16 . The LG connector 18 is detachably connected to the light source device 20, whereby the illumination light is transmitted to an illumination optical system 54 (see FIG. 2 ) which will be des...

Abstract

A hood 200 for an endoscope has a tube shape and is fitted to an end of an insertion part 12 of the endoscope. A base end 200B of the hood 200 is fitted to a forward end 60A of a first balloon 60. The forward end 60A of the first balloon 60 is fixed to the insertion part 12.

Description

technical field [0001] The present invention relates to an endoscope cover, an endoscope, and a method for fixing an endoscope balloon, and more particularly to an endoscope in which an endoscope cover and an endoscope balloon are attached to the front end of an insertion portion. mirror. Background technique [0002] When the insertion part of the endoscope is inserted into the deep alimentary canal such as the small intestine, due to the complicated curvature of the intestine, it is difficult to transmit force to the front end of the insertion part simply by pushing the insertion part, making deep insertion difficult. For example, if excessive bending or bending occurs in the insertion part, the insertion part cannot be inserted into a deeper part. Therefore, a method proposed is to cover an insertion assisting device on an insertion part of an endoscope and insert it into a body cavity, and guide the insertion part with the insertion assisting device to prevent unnecessa...
