Description

【0001】
【発明の属する技術分野】
この発明は、挿入部が患者の体壁に直接接触しないようにするための弾力性のある筒状カバーが着脱自在に設けられた汚染防止型内視鏡に関する。
【0002】
【従来の技術】
汚染防止型内視鏡は一般に、内視鏡の挿入部を外部から遮蔽するための弾力性のある筒状カバーを挿入部に着脱自在に被覆できるようになっており、筒状カバーを一回ごとに取り替えることにより、内視鏡による患者間の感染を完全に阻止することができる。
【0003】
【発明が解決しようとする課題】
内視鏡を用いて各種様々な処置が行われているが、内視鏡自体の先端部分に膨縮自在なバルーンを取り付けることにより、食道静脈瘤等の出血源の圧迫止血や、穿刺処置時の針先の振れ防止、或いは被写体との観察距離の確保等が行われている。
【0004】
しかし、上述のような汚染防止型内視鏡の挿入部の先端にそのようなバルーン機能を付加しようとすると、挿入部に被せられる筒状カバーにバルーンを取り付けなければならないので、構造が複雑化してコストアップになり、使い捨てすることにより非常に不経済なものになっていた。
【0005】
そこで本発明は、挿入部が患者の体壁に直接接触しないようにする筒状カバーに、使い捨てにしてもコスト上昇にならないようにバルーン機能を付加することができる汚染防止型内視鏡を提供することを目的とする。
【0006】
【課題を解決するための手段】
上記の目的を達成するため、本発明の汚染防止型内視鏡は、挿入部の先端に観察窓が配置されると共に、挿入部外に通じる流体通過管路が挿入部の先端に開口し、挿入部を外部から遮蔽するように挿入部に着脱自在に被覆される弾力性のある材料からなる筒状カバーが設けられた汚染防止型内視鏡において、筒状カバーを挿入部の先端近傍の外周面に気密に緊縛する気密緊縛手段を設けたものである。
【0007】
なお、気密緊縛手段が、挿入部の先端近傍の外周面に形成された周状溝に筒状カバーを外面側から緊縛する弾力性のある材料からなる締め環であってもよい。
また、周状溝が、遠隔操作によって屈曲自在に挿入部の先端付近に形成された湾曲部の後端付近に形成されていてもよく、或いは、湾曲部より先側位置に形成されていてもよい。
【0008】
【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、内視鏡10にカバー装置20が取り付けられていない状態を示している。
【0009】
内視鏡10の挿入部11は、長さが例えば50cm〜1.5m程度の可撓管11aの先端に、長さが例えば5〜10cm程度の湾曲部11bが連結され、湾曲部11bの先端に連結された先端部本体11cに観察窓16等が配置されたものである。
【0010】
挿入部11の基端には、湾曲部11bの遠隔操作を行う装置等が配置された操作部12が連結されており、湾曲部11bを二点鎖線で示されるように任意に屈曲させることができる。
【0011】
また、挿入部11内に全長にわたって挿通配置された流体通過管路18の先端開口17が先端部本体11cに配置され、基端側開口19が操作部12に配置されている。
【0012】
したがって、基端側開口19に注射器50等を接続することにより、流体通過管路18を経由して先端開口17から吸気及び送気(又は送水)を行うことができる。
【0013】
挿入部11の基端が連結されている操作部12の下端部分には、カバー装置20の筒状口金23が着脱自在に係合する円柱状の口金係止部13が形成されている。
【0014】
カバー装置20の大半の部分は、例えばシリコンゴム等のような弾力性のある材料によって形成されて挿入部11を外部から遮蔽するように挿入部11に被覆される円筒状の筒状カバー21である。
【0015】
筒状カバー21の先端は先端部本体11cに円滑に被嵌される先端キャップ22によって封止されている。その結果、筒状カバー21は基端開口以外の部分が全て塞がれた状態になっている。
【0016】
筒状カバー21の基端には、内視鏡10の口金係止部13に対して係脱自在な筒状口金23が取り付けられている。筒状口金23は、口金係止部13に嵌合する筒状に形成されていて、その側壁に内方に貫通するように形成されたネジ孔に、手動ネジ24が螺合している。手動ネジ24の頭部には、外側から手で摘むことのできる摘みが形成されている。
【0017】
したがって、筒状口金23を口金係止部13に嵌合させて手動ネジ24を締め込むことにより筒状口金23が口金係止部13に固定され、手動ネジ24を緩めれば、筒状口金23を口金係止部13から離脱させることができる。
【0018】
また、内視鏡10の湾曲部11bの後端部分には、全周にわたって凹んだ周状溝15が形成されており、挿入部11に被せられた筒状カバー21を弾力性のあるゴム材からなる締め環30(気密緊縛手段)により周状溝15に締め付けることができるようになっている。
【0019】
図1は、筒状カバー21内いっぱいに挿入部11が挿入されて、筒状口金23が口金係止部13に被せられ、手動ネジ24が締め込まれて筒状口金23が口金係止部13に係止された状態を示している。
【0020】
この状態では、内視鏡10の挿入部11がカバー装置20によって完全に被覆されており、締め環30を装着する前に、先端開口17から吸引をしてカバー装置20と挿入部11との間の空間を負圧にすることにより、筒状カバー21が挿入部11の外周面に密着する。
【0021】
そして、筒状カバー21の外面を囲むように締め環30を弾力的に引き伸ばして、図1に示されるように、挿入部11に形成されている周状溝15を締め付ける位置に締め環30をセットする。
【0022】
それによって、筒状カバー21が周状溝15の位置において挿入部11の外周面に気密に弾力的にきつく緊縛固定され、先端開口17からカバー装置20内の空間に送気(又は送水)をすることによって、二点鎖線で示されるように、筒状カバー21が締め環30より先側の部分において側方にバルーン状に膨らみ、排気(又は排水)をすれば元の状態に戻る。
【0023】
このようにして、カバー装置20に締め環30を装着するだけで、弾力性のある筒状カバー21の先端近傍部分を膨縮自在なバルーンにすることができ、食道静脈瘤等の出血源の圧迫止血等の処置を行うことができる。
【0024】
なお、先端キャップ22の後端部には、先端部本体11cの外周面に形成された溝14に対して係脱する爪22aが内方に向けて数カ所に突出形成されていて、先端部本体11cに対する先端キャップ22の位置ずれを防止している。
【0025】
図3は、本発明の参考例を示しており、第1の実施例の先端キャップ22に代えて、筒状カバー21の先端部分を筒状部と一体に弾力性のある材料によって形成すると共に、湾曲部11bとその先側の先端部本体11cとの連結部付近に周状溝15を形成したものである。
【0026】
このようにすることにより、二点鎖線で示されるように、筒状カバー21が挿入部11の最先端部において前方にバルーン状に膨らみ、被写体との間の観察距離の確保等を行うのに適している。
【0027】
【発明の効果】
本発明によれば、内視鏡の挿入部を外部から遮蔽するように挿入部に着脱自在に被覆される弾力性のある材料からなる筒状カバーが設けられた汚染防止型内視鏡において、筒状カバーを挿入部の先端近傍の外周面に気密に緊縛する気密緊縛手段を付加するだけで、筒状カバー自体をバルーンとして利用することができるので、筒状カバーを使い捨てにしてもコスト上昇になることなく、バルーン機能を利用した内視鏡的処置を容易に行うことができる。

BACKGROUND OF THE INVENTION
The present invention relates to a contamination-preventing endoscope in which an elastic cylindrical cover for preventing an insertion portion from directly contacting a patient's body wall is detachably provided.
[0002]
[Prior art]
In general, an anti-contamination endoscope is configured such that an elastic cylindrical cover for shielding the insertion portion of the endoscope from the outside can be detachably covered on the insertion portion. By replacing every time, infection between patients by the endoscope can be completely prevented.
[0003]
[Problems to be solved by the invention]
Various treatments are performed using an endoscope, but by attaching a balloon that can be inflated and contracted to the distal end of the endoscope itself, it is possible to stop hemorrhage such as esophageal varices or to stop bleeding and perform puncture treatment. In order to prevent the needle tip from moving, the observation distance from the subject is ensured.
[0004]
However, if such a balloon function is to be added to the distal end of the insertion portion of the contamination-preventing endoscope as described above, the balloon must be attached to the cylindrical cover that covers the insertion portion, which complicates the structure. The cost was increased, and it was very uneconomical by disposable.
[0005]
Therefore, the present invention provides a pollution-preventing endoscope capable of adding a balloon function to a cylindrical cover that prevents the insertion portion from directly contacting a patient's body wall so that the cost does not increase even if it is disposable. The purpose is to do.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the contamination-preventing endoscope according to the present invention has an observation window disposed at the distal end of the insertion portion, and a fluid passage conduit communicating with the outside of the insertion portion opens at the distal end of the insertion portion. In a contamination-preventing endoscope provided with a cylindrical cover made of a resilient material that is detachably coated on an insertion portion so as to shield the insertion portion from the outside, the cylindrical cover is disposed near the distal end of the insertion portion. An airtight binding means for airtightly binding to the outer peripheral surface is provided.
[0007]
The airtight binding means may be a fastening ring made of an elastic material that binds the cylindrical cover from the outer surface side to a circumferential groove formed on the outer peripheral surface near the distal end of the insertion portion.
Further, the circumferential groove may be formed in the vicinity of the rear end of the bending portion formed in the vicinity of the distal end of the insertion portion so as to be bendable by remote operation, or may be formed in a position ahead of the bending portion. Good.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described with reference to the drawings.
FIG. 2 shows a state where the cover device 20 is not attached to the endoscope 10.
[0009]
The insertion portion 11 of the endoscope 10 is connected to a distal end of a flexible tube 11a having a length of, for example, about 50 cm to 1.5 m, and a curved portion 11b having a length of, for example, about 5 to 10 cm. The observation window 16 and the like are arranged on the tip end body 11c connected to the.
[0010]
An operation unit 12 in which a device for remotely operating the bending portion 11b is arranged is connected to the proximal end of the insertion portion 11, and the bending portion 11b can be arbitrarily bent as indicated by a two-dot chain line. it can.
[0011]
In addition, a distal end opening 17 of a fluid passage pipe 18 that is inserted through the entire length of the insertion portion 11 is disposed in the distal end main body 11 c, and a proximal end opening 19 is disposed in the operation portion 12.
[0012]
Therefore, by connecting the syringe 50 or the like to the proximal end side opening 19, intake and air supply (or water supply) can be performed from the distal end opening 17 via the fluid passage pipe 18.
[0013]
At the lower end portion of the operation unit 12 to which the base end of the insertion unit 11 is connected, a columnar base locking part 13 is formed to which the cylindrical base 23 of the cover device 20 is detachably engaged.
[0014]
The most part of the cover device 20 is a cylindrical tubular cover 21 which is formed of a resilient material such as silicon rubber and is covered with the insertion portion 11 so as to shield the insertion portion 11 from the outside. is there.
[0015]
The distal end of the cylindrical cover 21 is sealed by a distal end cap 22 that is smoothly fitted to the distal end main body 11c. As a result, the cylindrical cover 21 is in a state where all portions other than the base end opening are closed.
[0016]
At the base end of the cylindrical cover 21, a cylindrical base 23 that is detachable with respect to the base locking portion 13 of the endoscope 10 is attached. The cylindrical base 23 is formed in a cylindrical shape that fits into the base locking portion 13, and a manual screw 24 is screwed into a screw hole formed so as to penetrate the side wall inwardly. The head of the manual screw 24 is formed with a knob that can be manually picked from the outside.
[0017]
Therefore, the cylindrical base 23 is fixed to the base locking part 13 by fitting the cylindrical base 23 to the base locking part 13 and tightening the manual screw 24. When the manual screw 24 is loosened, the cylindrical base 23 is fixed. 23 can be detached from the base locking portion 13.
[0018]
In addition, a circumferential groove 15 that is recessed over the entire circumference is formed at the rear end portion of the curved portion 11b of the endoscope 10, and the cylindrical cover 21 that covers the insertion portion 11 is made of an elastic rubber material. It can be fastened to the circumferential groove 15 by a fastening ring 30 (airtight binding means) made of
[0019]
In FIG. 1, the insertion portion 11 is inserted into the entire cylindrical cover 21, the cylindrical base 23 is put on the base locking portion 13, the manual screw 24 is tightened, and the cylindrical base 23 becomes the base locking portion. 13 shows a state of being locked.
[0020]
In this state, the insertion portion 11 of the endoscope 10 is completely covered with the cover device 20, and suction is performed from the distal end opening 17 before the fastening ring 30 is attached, so that the cover device 20 and the insertion portion 11 can be connected to each other. By making the space between them negative, the cylindrical cover 21 is in close contact with the outer peripheral surface of the insertion portion 11.
[0021]
Then, the fastening ring 30 is elastically extended so as to surround the outer surface of the cylindrical cover 21, and the fastening ring 30 is placed at a position for fastening the circumferential groove 15 formed in the insertion portion 11 as shown in FIG. 1. set.
[0022]
Accordingly, the cylindrical cover 21 is tightly fixed tightly and tightly and tightly to the outer peripheral surface of the insertion portion 11 at the position of the circumferential groove 15, and air (or water supply) is supplied from the distal end opening 17 to the space in the cover device 20. By doing so, as shown by a two-dot chain line, the cylindrical cover 21 swells in a balloon shape laterally at a portion ahead of the fastening ring 30 and returns to its original state when exhausted (or drained).
[0023]
In this way, by simply attaching the fastening ring 30 to the cover device 20, the portion near the tip of the elastic cylindrical cover 21 can be made into an inflatable and inflatable balloon. Treatment such as compression hemostasis can be performed.
[0024]
At the rear end portion of the tip cap 22, claws 22a that engage with and disengage from the grooves 14 formed on the outer peripheral surface of the tip portion main body 11c are formed to protrude inward at several points. The positional displacement of the tip cap 22 with respect to 11c is prevented.
[0025]
FIG. 3 shows a reference example of the present invention. Instead of the tip cap 22 of the first embodiment, the tip portion of the cylindrical cover 21 is formed of a resilient material integrally with the cylindrical portion. The circumferential groove 15 is formed in the vicinity of the connecting portion between the curved portion 11b and the tip end body 11c on the tip side.
[0026]
By doing so, as indicated by a two-dot chain line, the cylindrical cover 21 swells forward in a balloon shape at the most distal end portion of the insertion portion 11 to secure an observation distance from the subject. Is suitable.
[0027]
【The invention's effect】
According to the present invention, in the pollution-preventing endoscope provided with the cylindrical cover made of a resilient material that is detachably covered by the insertion portion so as to shield the insertion portion of the endoscope from the outside, The cylindrical cover itself can be used as a balloon simply by adding an airtight binding means that tightly binds the cylindrical cover to the outer peripheral surface near the distal end of the insertion portion, so the cost increases even if the cylindrical cover is disposable. Therefore, endoscopic treatment using the balloon function can be easily performed.
