Abstract

PURPOSE:To easily turn an endoscope with grasping an inserting part by providing elastic irregularities to contact the outer circumference of the inserting part in the inner surface of a grasping part, which can reduce a diameter to be smaller than the outer diameter of the inserting part by being grasped. CONSTITUTION:An inserting part 4 of the endoscope is inserted to a hole 9a of a base 9 in an insertion supporting tool 6. In such a case, a prescribed interval exists between an inner surface 9b of the hole 9a and an outer circumference 4b of the inserting part 4 and a part, in which a fricting member 13 is provided, is separated from the outer circumference 4b. Next, a tip part 4a of the inserting part 4 is engaged to the aperture edge of an observed part. When a grasping part 1 of the supporting tool 6 is grasped, the supporting tool and observed part are turned in a direction, where they are mutually converged, and an inner surface 13a of the fricting member 13 contacts the outer circumference 4b. In such a condition, the inserting part 4 is inserted in the direction of the observed part. When the supporting tool 6 is closed to the aperture edge of the observed part, grasping force to the grasping part 12 is made weak. Then, the edge part of this grasping part 12 in a side to be separated from the base is separated from the outer circumference 4b of the inserting part 4 and the friction member 13 is easily separated from the outer circumference 4b.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an endoscope insertion aid whose insertion portion can be grasped and easily rotated or inserted.

[Prior art and problems to be solved by the invention] In recent years, by inserting an elongated insertion section into a body cavity, Wa

Description of the Related Art Medical endoscopes are widely used for observing instruments and performing various therapeutic treatments using a treatment instrument inserted into a treatment instrument channel as necessary. Furthermore, in the industrial field, industrial endoscopes that can inspect or inspect the interior of boilers, turbines, engines, chemical plants, etc. are widely used.

It has long been known to general users that when inserting the above-mentioned insertion section into the part to be observed, it is possible to insert it more smoothly by rotating the tip instead of just inserting it. . When the length of the insertion portion is relatively short, this rotation of the distal end portion can be performed by rotating an operating portion connected to the insertion portion.

However, some of the above-mentioned endoscopes have quite long insertion sections, and in particular, some endoscopes for industrial use have lengths of 10 m to 20 m.

When the insertion portion becomes such a long length, even if the operation portion is rotated, this rotation is absorbed by the insertion portion, making it difficult to rotate the distal end portion. To deal with this, it is conceivable to rotate the distal end by grasping and rotating the insertion section, but with medical endoscopes, if the operator directly touches the insertion section, may become contaminated or infected.

Therefore, in Japanese Utility Model Application Publication No. 50-26291, the present applicant proposed an insertion endoscope having a flexible cylindrical body that can be inserted into the insertion section and flange bodies provided at both ends of the cylindrical body. Suggesting aids. However, this prior art only avoids the operator from directly touching the insertion section, and there is difficulty in grasping and rotating the insertion section via this insertion aid.

In particular, when inserting an industrial endoscope, oils such as glue may adhere to the insertion part, making it difficult to rotate this part even if it is grasped using the insertion aid according to the prior art described above. There are many cases.

The present invention has been made in view of the above-mentioned circumstances, and provides an endoscope insertion aid that can grasp the insertion part and easily rotate it, regardless of whether it is for industrial or medical use. It is intended to.

[Means and effects for solving the problem] The endoscope insertion aid according to the present invention includes a gripping portion whose diameter can be reduced to a diameter smaller than the outer diameter of the insertion portion by grasping it, and the gripping portion. The insertion portion is provided with elastic unevenness provided on the inner surface thereof and comes into contact with the outer periphery of the insertion portion.

With such a configuration, the diameter of the gripping portion is made smaller than the outer diameter of the insertion portion by engaging with the insertion portion of the endoscope and grasping the gripping portion, and is provided on the inner surface of the gripping portion. It is held in the insertion part via the unevenness and the insertion part is rotated.
