Problems solved by technology

[0012] However, such balloon overtubes tend to slip inside said overtube
In addition, in the case of an overtube for the large intestine, it is configured to cover the entire length of the insertion part, so the twisting operation of the insertion part, or the operation of pulling the overtube and the insertion part together when the intestinal tube is pulled closer by the balloon, is carried out together with the overtube. It is difficult to operate the endoscope

Abstract

The present invention relates to an endoscope insertion aid and endoscope apparatus, the endoscope insertion aid includes: a tubular member which allows an insertion portion of an endoscope to be passed through in a manner being capable of moving forward and backward. A holding unit, which is provided on an outer peripheral side of the tubular member, can be inflated and deflated. A thread-like member, which is connected at one end to the tubular member and passed at the other end into a channel, extends from an opening of the channel. A thread-like member fixing unit which restrains the thread-like member and thereby restricts movement of the tubular member. A restraining member which supplies and discharges the fluid into / from the holding unit, being disposed to the insertion portion, being connected at one end to the tubular member, extends at the other end to the proximal end side of the insertion portion. A restraining member fixing unit which holds the tubular member.

Description

technical field [0001] The present invention relates to an endoscope insertion aid and an endoscope device suitable for smoothly inserting an insertion portion of an endoscope into intestinal tracts such as the large intestine or the small intestine. Background technique [0002] Generally, an endoscope has an operation unit including a switch and the like, which is grasped by an operator to perform various operations, and an insertion unit that is inserted into the body. The insertion part is configured such that a front end part, a bending part, and a flexible tube part are continuously provided in this order from the front end side. The flexible tube part is elongated and flexible, and extends from the operation part. The bending portion is provided continuously to the front end of the flexible tube portion, and is configured to be bendable in the left and right or up and down directions by the operation of the operation portion. The front end portion has a rigid front ...
