Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to an endoscope apparatus having an elongated insertion portion.

[0002]

2. Description of the Related Art Endoscope devices are widely used in medical fields and industrial fields. BACKGROUND ART As an endoscope apparatus used in the industrial field, there is an endoscope apparatus in which a slender endoscope insertion portion is inserted into a jet engine or a pipe of a power plant to observe a test site and perform various treatments. For example, the present applicant has proposed that the endoscope of Japanese Patent Application No. 2001-022203 has an operation part which is an insertion part or a universal part in order to improve not only the bending operability but also the insertion operability of the insertion part and the operability of the treatment tool. We have proposed a technology that allows the cord to be detachably attached to any position.

When handling an industrial endoscope having an elongated insertion portion, it is sometimes necessary to insert the insertion portion at a position higher than the operator's back for observation. At that time, the insertion part may hang down and fall by its own weight.Therefore, when inserting at a high position for observation, in order to prevent the insertion part from falling, the user repeatedly holds and inserts the object. It had been inserted to the site.

[0004]

However, when inserting the insertion portion by holding the operation portion or the remote controller with one hand and holding the insertion portion with the other hand, insertion and holding of the insertion portion are performed by one hand. Even if the operation is performed, the insertion portion may be temporarily held by the hand holding the operation portion or the remote controller.
At that time, when trying to hold the insertion section together with the operation section or the remote controller, there is a risk that the insertion section cannot be sufficiently held and the insertion section is dropped. Further, when the insertion portion is soiled with oil or water, the hand of the operator who holds the operating portion is also soiled with oil or water.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an endoscope apparatus in which the insertion portion can be easily and surely held by the hand holding the operation portion or the remote controller. .

[0006]

The endoscope apparatus of the present invention comprises:
An endoscope having flexibility and an elongated insertion portion having a bending portion, a remote controller for remotely operating the bending portion of the endoscope, and a remote controller detachably attached to the insertion portion. And an insertion portion holder through which the part is inserted and arranged.

Further, the insertion portion holder is provided with a mounting portion which is attachable to and detachable from the remote controller, and an insertion portion insertion portion through which the insertion portion is inserted.

Further, the insertion portion insertion portion of the insertion portion holder has an elastic force.

According to this structure, first, the mounting portion is arranged on the remote controller and the insertion portion holder is integrally mounted on the remote controller. Next, the insertion portion of the endoscope is arranged in the insertion portion insertion portion of the insertion portion holder, and the user grips the remote controller together with the insertion portion holder, so that the insertion portion can be remoted without directly touching the insertion portion. The insertion part can be held by the hand holding the controller. Furthermore, by changing the gripping force for gripping the remote controller, the insertion portion can be moved back and forth.

The attachment of the insert holder 9 to the remote controller 6 and the operation of the insert holder 9 will be described with reference to FIGS. First, as shown in FIGS. 8A and 8B, the insert holder 9 is attached to the remote controller 6. At this time, first, the mounting recess 91 is fitted into the grip portion of the remote controller 6 by pressing and widening the narrow openings of the placement side walls 91a and 91b, and the one projection 92a is fixed to the position fixing recess 62.
Fit in b. Then, the mounting recess 91 is pushed in, and the other projection 92b is fitted into the position fixing recess 62a. As a result, the insertion portion holder 9 is integrally attached to the remote controller 6 such that the placement side walls 91a and 91b forming the attachment recess 91 sandwich the side surface of the grip portion of the remote controller 6. The insertion section holder 9 is configured such that the insertion section insertion section 93 can be attached to the remote controller 6 in either the left or right direction. That is, for example, when arranging in the opposite direction to that of FIG. 8A, the protrusion 92a is fitted in the position fixing recess 62a, and the other protrusion 92b is fitted in the position fixing recess 62b.
