Description

【０００１】
【発明の属する技術分野】
この発明は、被験者の口から挿入される内視鏡の挿入部が被験者によって噛まれないように保護するための内視鏡の挿入部噛まれ防止具に関する。
【０００２】
【従来の技術】
内視鏡の挿入部噛まれ防止具は一般に、内側に挿通される内視鏡挿入部が被験者に噛まれないように被験者によって噛んで保持される筒状部と、その筒状部が被験者の口内に潜ってしまわないように筒状部の外縁部に突設された鍔状部とによって構成されている。
【０００３】
【発明が解決しようとする課題】
内視鏡検査は、上述のような挿入部噛まれ防止具内に内視鏡挿入部を通して、片手で内視鏡操作部を保持し、もう一方の手で内視鏡挿入部の挿入操作を行うのが普通である。
【０００４】
しかし、鉗子の使用や薬液類の散布等各種の内視鏡的処置（「内視鏡を介して行われる処置」の意）は、内視鏡挿入部を保持している方の手で行わざるを得ないので、内視鏡的処置を行う間は内視鏡挿入部から手を放すことになる。
【０００５】
すると、内視鏡挿入部が体内から抜け出す方向（場合によっては、さらに挿入される方向）に移動してしまって、目標とする患部を捕捉するための挿入操作をやり直さなければならず、内視鏡検査に徒に時間がかかってしまう場合があった。
【０００６】
そこで本発明は、内視鏡的処置等を行う間に内視鏡挿入部が挿脱方向に移動しないようにして、内視鏡検査を円滑に行うことができる内視鏡の挿入部噛まれ防止具を提供することを目的とする。
【０００７】
【課題を解決するための手段】
上記の目的を達成するため、本発明の内視鏡の挿入部噛まれ防止具は、内側に挿通される内視鏡挿入部が被験者に噛まれないように被験者によって噛んで保持される筒状部が形成された内視鏡の挿入部噛まれ防止具において、筒状部内に位置する内視鏡挿入部を筒状部に対して保持及び解除自在な挿入部保持部材を設けたものである。
【０００８】
なお、挿入部保持部材に、内視鏡挿入部を挟み付けて保持する一対の挿入部保持アームが形成されており、挿入部保持アームは弾性変形させることにより内視鏡挿入部に対して係脱自在であるようにしてもよい。
【０００９】
また、挿入部保持部材が、筒状部に対して固定及び分離自在であってもよい。
【００１０】
【発明の実施の形態】
図面を参照して本発明の実施例を説明する。
図２は、被験者の口にくわえられた挿入部噛まれ防止具１０の筒状部１１内に、内視鏡の挿入部１００が通された状態を示している。
【００１１】
挿入部噛まれ防止具１０は、被験者によって噛まれた状態で保持される中空の小判状の断面形状の筒状部１１と、その筒状部１１が被験者の口内に潜ってしまわないように筒状部１１の外縁部に突設された鍔状部１２とを、プラスチック材で一体に形成して構成されている。
【００１２】
そして、筒状部１１の外縁部の鍔状部１２の突出量の小さな部分には、筒状部１１内に位置する挿入部１００を挿入部噛まれ防止具１０に対して挿脱方向に移動しないように保持する挿入部保持部材２０が着脱自在に取り付けられている。
【００１３】
挿入部保持部材２０は、図３に示されるように、筒状部１１内を通る挿入部１００を挟み付けて保持する一対の挿入部保持アーム２１と、挿入部噛まれ防止具１０に対して着脱自在な噛まれ防止具側着脱部２２とが、プラスチック材により一体成形されて構成されている。
【００１４】
噛まれ防止具側着脱部２２は、Ｊ字状の断面形状に形成されており、弾性変形させることにより筒状部１１の口元部分に係止及び分離させることができる。
噛まれ防止具側着脱部２２側から並んで突設された一対の挿入部保持アーム２１は、挿入部１００を挟み付ける中間部分が挿入部１００の外面に沿う円弧状にカーブして形成され、弾性変形させて隙間を少し広げることにより挿入部１００を間に出し入れすることができる。
【００１５】
このような構成により、図４及びそのＩ−Ｉ断面を図示する図１に示されるように、一対の挿入部保持アーム２１の間に挿入部１００を挟み込むと、一対の挿入部保持アーム２１が弾力的に少し押し広げられたままの状態になり、その弾性力によって挿入部１００が保持された状態になる。
【００１６】
したがって、術者が内視鏡的処置等を行うために挿入部１００から手を離さざるを得ない時は、挿入部１００を一時的に挿入部保持部材２０に保持させ、内視鏡的処置が済んだら、挿入部１００を挿入部保持部材２０から外して手で握り、次の挿入操作を行うことができる。
【００１７】
そして挿入部保持部材２０は、噛まれ防止具側着脱部２２を弾性変形させることにより挿入部噛まれ防止具１０に対して固定／分離自在なので、使用されている内視鏡の挿入部１００の径に最も適した挿入部保持部材２０を適宜選択して使用することができる。
【００１８】
【発明の効果】
本発明によれば、筒状部内に位置する内視鏡挿入部を筒状部に対して保持及び解除自在な挿入部保持部材を設けたことにより、内視鏡的処置等を行う間は内視鏡挿入部が挿脱方向に移動しないようにして、内視鏡検査を円滑に行うことができる。

BACKGROUND OF THE INVENTION
The present invention relates to an endoscope insertion portion biting prevention tool for protecting an insertion portion of an endoscope inserted from the mouth of a subject from being bitten by a subject.
[0002]
[Prior art]
An endoscope insertion portion biting prevention device generally has a cylindrical portion that is bitten and held by a subject so that the endoscope insertion portion inserted inside is not bitten by the subject, and the cylindrical portion is It is comprised by the hook-shaped part protruded by the outer edge part of the cylindrical part so that it may not divide into the mouth.
[0003]
[Problems to be solved by the invention]
Endoscopy is performed by passing the endoscope insertion part through the insertion part bite prevention tool as described above, holding the endoscope operation part with one hand, and inserting the endoscope insertion part with the other hand. Usually done.
[0004]
However, various endoscopic procedures such as the use of forceps and spraying of chemicals (meaning “treatment performed through an endoscope”) are performed by the hand holding the endoscope insertion portion. Inevitably, the hand is released from the endoscope insertion portion during the endoscopic treatment.
[0005]
Then, the endoscope insertion part moves in the direction of getting out of the body (in some cases, the direction of further insertion), and the insertion operation for capturing the target affected part must be performed again. In some cases, the mirror examination took time.
[0006]
Accordingly, the present invention provides an endoscope insertion portion that can smoothly perform an endoscopic examination by preventing the endoscope insertion portion from moving in the insertion / removal direction during endoscopic treatment or the like. It aims at providing a preventive tool.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, the endoscope insertion portion biting prevention device of the present invention has a cylindrical shape that is held by the subject so that the endoscope insertion portion inserted inside is not bitten by the subject. In an endoscope insertion portion biting prevention tool in which a portion is formed, an insertion portion holding member is provided that can hold and release the endoscope insertion portion located in the cylindrical portion with respect to the cylindrical portion. .
[0008]
Note that a pair of insertion portion holding arms that sandwich and hold the endoscope insertion portion is formed on the insertion portion holding member, and the insertion portion holding arms are elastically deformed to engage with the endoscope insertion portion. It may be made removable.
[0009]
Further, the insertion portion holding member may be fixed and separable with respect to the cylindrical portion.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described with reference to the drawings.
FIG. 2 shows a state in which the insertion portion 100 of the endoscope is passed through the cylindrical portion 11 of the insertion portion biting prevention tool 10 held in the mouth of the subject.
[0011]
The insertion portion biting prevention device 10 includes a hollow oval cross-sectional cylindrical portion 11 that is held in a state of being bitten by a subject, and a cylinder so that the cylindrical portion 11 does not dive into the mouth of the subject. The hook-like portion 12 projecting from the outer edge portion of the shaped portion 11 is integrally formed of a plastic material.
[0012]
And the insertion part 100 located in the cylindrical part 11 is moved in the insertion / removal direction with respect to the prevention tool 10 in the part with a small protrusion amount of the flange part 12 of the outer edge part of the cylindrical part 11. An insertion portion holding member 20 is attached so as not to be detached.
[0013]
As shown in FIG. 3, the insertion portion holding member 20 has a pair of insertion portion holding arms 21 that sandwich and hold the insertion portion 100 passing through the cylindrical portion 11, and the insertion portion biting prevention tool 10. A removable biting prevention tool side attaching / detaching portion 22 is integrally formed of a plastic material.
[0014]
The biting prevention tool side attaching / detaching portion 22 is formed in a J-shaped cross-sectional shape, and can be locked and separated from the mouth portion of the tubular portion 11 by elastic deformation.
The pair of insertion portion holding arms 21 projecting side by side from the biting prevention device side attaching / detaching portion 22 side is formed such that an intermediate portion sandwiching the insertion portion 100 is curved in an arc shape along the outer surface of the insertion portion 100, The insertion part 100 can be taken in and out by slightly elastically deforming and widening the gap.
[0015]
With such a configuration, as shown in FIG. 4 and FIG. 1 illustrating its II cross section, when the insertion portion 100 is sandwiched between the pair of insertion portion holding arms 21, the pair of insertion portion holding arms 21 is The insertion portion 100 is held in a state where it is elastically pushed a little, and its elastic force.
[0016]
Therefore, when the surgeon has to release his / her hand from the insertion portion 100 in order to perform an endoscopic treatment or the like, the insertion portion 100 is temporarily held by the insertion portion holding member 20 to perform an endoscopic treatment. When the operation is completed, the insertion section 100 can be removed from the insertion section holding member 20 and grasped by hand to perform the next insertion operation.
[0017]
Since the insertion portion holding member 20 can be fixed / separated with respect to the insertion portion biting prevention device 10 by elastically deforming the biting prevention device side attaching / detaching portion 22, the insertion portion holding member 20 of the endoscope used in the insertion portion 100 is used. The insertion portion holding member 20 most suitable for the diameter can be appropriately selected and used.
[0018]
【The invention's effect】
According to the present invention, by providing the insertion portion holding member that can hold and release the endoscope insertion portion located in the cylindrical portion with respect to the cylindrical portion, the endoscope insertion portion is provided during endoscopic treatment or the like. Endoscopic examination can be performed smoothly by preventing the endoscope insertion portion from moving in the insertion / removal direction.
