Description

【０００１】
【発明の属する技術分野】
この発明は、内視鏡用鉗子栓の閉鎖膜からの漏れを検出するための内視鏡用鉗子栓の漏れ検出装置に関する。
【０００２】
【従来の技術】
内視鏡には一般に、処置具類を挿通するための処置具挿通チャンネルが設けられていて、その入口である処置具挿入口には、体内の汚液等が処置具挿通チャンネルを通って、噴出するのを防止するための鉗子栓が取り付けられている。
【０００３】
そのような鉗子栓は、一般に、基端側が内視鏡の処置具挿入口に着脱自在に取り付けられ、弾力性のある材料からなる閉鎖膜に形成されて通常は閉じた状態にあるスリットが、処置具挿入口に挿入される処置具によって押し開かれるようになっている。
【０００４】
また、処置具が通された状態での漏れを防止するために、処置具のシースを弾力的に締め付ける径の小孔がもう一つの閉鎖膜に形成されて配置されている。
【０００５】
【発明が解決しようとする課題】
そのような閉鎖膜に形成された小孔は、処置具挿入が繰り返されることによって磨耗あるいは変形して密閉性が低下する。そのため、体内の汚液等が処置具挿通チャンネルを通って漏れ出し、周辺を汚染してしまう場合がある。
【０００６】
そこで本発明は、鉗子栓の閉鎖膜に形成された小孔からの漏れ発生を事前に検出して、体内の汚液等が処置具挿通チャンネルを通って漏れ出すことを未然に防止することができる内視鏡用鉗子栓の漏れ検出装置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、本発明の内視鏡用鉗子栓の漏れ検出装置は、内視鏡の処置具挿入口に着脱自在に取り付けられてそこを通過する処置具を締め付ける径の小孔が弾力性のある材料からなる閉鎖膜に形成された内視鏡用鉗子栓の小孔部分からの漏れを検出するための内視鏡用鉗子栓の漏れ検出装置であって、鉗子栓の入口側から小孔に挿脱自在な棒材と、棒材が小孔に挿入された状態において鉗子栓に対する棒材のそれ以上の挿入を規制するストッパとが設けられ、鉗子栓に対する棒材の挿入がストッパにより規制された状態においては、小孔が棒材を弾力的に締め付けた状態になると共に、ストッパが鉗子栓内と外部との連通を妨げないようにしたものである。
【０００８】
なお、小孔の断面形状と棒材の断面形状が共に円形であり、棒材の径が小孔の径より大きいとよく、棒材の小孔の裏側に達する部分に、小孔からの抜け出しを規制する太径部が形成されていてもよい。
【０００９】
また、棒材がストッパに対して着脱自在であり、あい異なる形状に形成された複数の棒材を選択してストッパに取り付けることができるようにしてもよい。
【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７は、内視鏡１００の処置具挿入口１０２部分に基端部が着脱自在に取り付けられる内視鏡用鉗子栓１１０の一例を示している。
【００１１】
処置具挿入口１０２は、処置具挿通チャンネル１０１の入口であり、この実施例ではいわゆるルアーロック式注射針の口金状に形成されて、内視鏡１００の操作部に突設されている。
【００１２】
鉗子栓１１０は全体が弾力性のあるゴム材によって形成されていて、処置具挿入口１０２に取り付けられる樽状部１１１と、その樽状部１１１の入口部分に着脱自在な蓋状部１１２とからなる。蓋状部１１２は、基端が処置具挿入口１０２に取り付けられるつなぎ部１１３の先端に形成されている。
【００１３】
樽状部１１１の内部に形成された閉鎖膜１１４の中央には、処置具挿入口１０２に対向するように円形の小孔１１５が形成され、蓋状部１１２の内部に形成された閉鎖膜１１６の中央には、−状のスリット１１７が形成されている。小孔１１５は挿通される処置具のシースの径より小さな径に形成され、スリット１１７はシースの直径より長く形成されている。
【００１４】
このような構成により、通常は閉じた状態にあるスリット１１７が処置具挿入口１０２に挿入される処置具（図示せず）によって押し開かれ、小孔１１５は、挿通される処置具のシースを弾力的に締め付けるようにシースの外面に密着して、処置具挿通時の漏れ防止に寄与する。
【００１５】
図２は、鉗子栓１１０の漏れを検出する装置を示しており、鉗子栓１１０の基端側に気密に接続自在な対鉗子栓接続部材２と、加圧気体を送り出す送気装置５０の送気口金５１に気密に接続される対送気装置接続部材２との間が、可撓性チューブ３等により連通接続されている。
【００１６】
対鉗子栓接続部材２は、例えば内視鏡１００の処置具挿入口１０２と同形状のもの等であればよく、可撓性チューブ３は四フッ化エチレン樹脂チューブ又はシリコンチューブ等によって形成される。
【００１７】
送気装置５０は、鉗子栓１１０の漏れ検査に適した圧力の加圧気体を送出するものであれば何でもよく、内視鏡用光源装置に組み込まれている送気装置をそのまま利用することができる。
【００１８】
２０は、鉗子栓１１０の小孔１１５と処置具のシースとの間からの漏れを検出するために漏れ検査時に鉗子栓１１０に差し込まれる漏れ検出アダプタであり、図３に側面断面が拡大図示され、図１には鉗子栓１１０に差し込まれた状態が図示されている。
【００１９】
漏れ検出アダプタ２０は、鉗子栓１１０の入口側から小孔１１５に挿脱自在な小孔挿入棒材２２（棒材）と、その小孔挿入棒材２２が小孔１１５に挿入された状態において鉗子栓１１０の表面に当接して、鉗子栓１１０に対する小孔挿入棒材２２のそれ以上の挿入を規制するキャップ状部材２１（把持部兼ストッパ）とによって形成されている。
【００２０】
小孔挿入棒材２２は、その鉗子栓１１０に挿通される処置具のシースの径（標準径）と同じ径の円形断面に形成されており、キャップ状部材２１が鉗子栓１１０の表面に当接した状態において、小孔挿入棒材２２が小孔１１５を弾力的に押し広げて、小孔１１５が小孔挿入棒材２２を締め付けた状態になる。
【００２１】
したがって、小孔１１５に磨耗や変形がなければ小孔挿入棒材２２の外周面と小孔１１５とは全面でよく密着する。一方、スリット１１７は、小孔挿入棒材２２が差し込まれることにより、弾力的に押し広げられて周辺部分が開いたままの状態になる。
【００２２】
また、小孔１１５が形成されている閉鎖膜１１４を境界とする内外圧力差（内圧＞外圧）等により、意に反して小孔挿入棒材２２が小孔１１５から抜け出す恐れがある。
【００２３】
そこで、小孔挿入棒材２２の先端には、小孔挿入棒材２２より大きな径の球状の抜け止め部２２ｂが形成されていて、小孔１１５の裏側縁部に軽く引っ掛かるようになっている。ただし、少し大きな力を加えれば、抜け止め部２２ｂも小孔１１５を通過する。
【００２４】
キャップ状部材２１には、図４の正面図にも示されるように、側面壁と端面壁に各々複数の通気部２３が形成されていて、鉗子栓１１０内と外部との連通をキャップ状部材２１が妨げないようになっている。
【００２５】
小孔挿入棒材２２の基端部分の外周には雄ネジ２２ａが形成されていて、キャップ状部材２１の中心位置に形成されている雌ネジ２１ａと係脱自在に螺合している。
【００２６】
したがって、その螺合を緩めれば小孔挿入棒材２２はキャップ状部材２１に対して変換自在であり、図５に示されるように、太さが相違する複数の小孔挿入棒材２２Ａ，２２Ｂを準備しておき、検査対象となる鉗子栓１１０に対応して適当な小孔挿入棒材２２を取り付け使用することができる。
【００２７】
また、図６に示されるように、漏れ検出アダプタ２０を鎖３０又は紐等によって漏れ検出装置の可撓性チューブ３等と連結しておけば、漏れ検出アダプタ２０が行方不明になったりせず管理上便利である。鎖３０の両端はいわゆるダブルリング等のようなリング状部材３１によって相手方に係合させればよい。
【００２８】
漏れ検出アダプタ２０そのものだけでなく漏れ検出装置の取り扱い説明書４０や他の寸法形状の漏れ検出アダプタ等も同様にして鎖３０を介して内視鏡用鉗子栓の漏れ検出装置に連結してもよく、その場合には、取り扱い説明書４０を連結する鎖３０を他の鎖より短くして、取り扱い説明書４０が邪魔にならないようにするとよい。
【００２９】
このような構成により、対送気装置接続部材１を送気装置５０に接続して、漏れ検出アダプタ２０が差し込まれた鉗子栓１１０に対鉗子栓接続部材２接続し、鉗子栓１１０を水中に漬けて送気装置５０の送気動作をオンにすると、小孔挿入棒材２２と小孔１１５との間の閉鎖状態が不完全なときは小孔１１５を通る空気が泡となって観察され、漏れ検出を行うことができる。なお、加圧空気に変えて加圧水を通して大気中で漏れ検査を行ってもよい。
【００３０】
なお、漏れ検出装置の各部に用いられる部材の材料は、オートクレーブ滅菌やＥＯＧガス滅菌等に耐えられるように、チューブ類には前出の通り四フッ化エチレン樹脂やシリコン樹脂等を用い、その他の構造材としては、ポリサルホン樹脂、ステンレス鋼、又は防錆処理された金属等を用いるとよい。
【００３１】
【発明の効果】
本発明によれば、棒材を鉗子栓に差し込むことによって鉗子栓の閉鎖膜に形成された小孔が棒材を弾力的に締め付ける状態になるので、そこに流体を通すことにより、閉鎖膜に形成された小孔部分からの漏れ発生を事前に検出して、体内の汚液等が処置具挿通チャンネルを通って漏れ出すことを未然に防止することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a leakage detection device for an endoscopic forceps plug for detecting leakage from the closure membrane of the endoscopic forceps plug.
[0002]
[Prior art]
Endoscopes are generally provided with a treatment instrument insertion channel for inserting treatment instruments, and in the treatment instrument insertion port, which is the entrance of the endoscope, sewage or the like passes through the treatment instrument insertion channel. A forceps plug is attached to prevent ejection.
[0003]
Such a forceps plug is generally provided with a slit that is normally attached in a closed state that is detachably attached to a treatment instrument insertion port of an endoscope and is formed in a closed membrane made of a resilient material. It is designed to be pushed open by a treatment instrument inserted into the treatment instrument insertion port.
[0004]
Further, in order to prevent leakage when the treatment instrument is passed, a small hole having a diameter for elastically tightening the sheath of the treatment instrument is formed and arranged in another closing membrane.
[0005]
[Problems to be solved by the invention]
The small hole formed in such a closing membrane is worn or deformed by repeated insertion of the treatment instrument, and the sealing performance is lowered. Therefore, sewage or the like in the body may leak through the treatment instrument insertion channel and contaminate the surrounding area.
[0006]
Therefore, the present invention can detect in advance leakage from a small hole formed in the closure membrane of the forceps plug and prevent leakage of sewage or the like in the body through the treatment instrument insertion channel. An object of the present invention is to provide a leakage detection device for an endoscopic forceps plug.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, the leakage detecting device for an endoscopic forceps plug of the present invention is a small hole having a diameter for detachably attaching to a treatment instrument insertion port of an endoscope and tightening a treatment instrument passing therethrough A device for detecting leakage of an endoscopic forceps plug for detecting leakage from a small hole portion of an endoscopic forceps plug formed on a closing membrane made of an elastic material, the entrance of the forceps plug A rod that can be inserted into and removed from the small hole from the side and a stopper that restricts further insertion of the rod into the forceps plug when the rod is inserted into the small hole are provided. In the state where the stopper is regulated by the stopper, the small hole is in a state of elastically tightening the bar, and the stopper does not prevent the communication between the inside of the forceps plug and the outside.
[0008]
The cross-sectional shape of the small hole and the cross-sectional shape of the bar are both circular, and the diameter of the bar should be larger than the diameter of the small hole. A large-diameter portion that regulates may be formed.
[0009]
Further, the bar may be detachable from the stopper, and a plurality of bars formed in different shapes may be selected and attached to the stopper.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described with reference to the drawings.
FIG. 7 shows an example of an endoscopic forceps plug 110 in which the proximal end portion is detachably attached to the treatment instrument insertion port 102 portion of the endoscope 100.
[0011]
The treatment instrument insertion port 102 is an inlet of the treatment instrument insertion channel 101, and in this embodiment, is formed in the shape of a so-called luer lock type injection needle and protrudes from the operation portion of the endoscope 100.
[0012]
The forceps plug 110 is entirely formed of a resilient rubber material, and includes a barrel-shaped portion 111 attached to the treatment instrument insertion port 102 and a lid-shaped portion 112 that is detachable from the inlet portion of the barrel-shaped portion 111. Become. The lid portion 112 is formed at the distal end of the connecting portion 113 attached to the treatment instrument insertion port 102 at the base end.
[0013]
A circular small hole 115 is formed in the center of the closure film 114 formed inside the barrel-like part 111 so as to face the treatment instrument insertion port 102, and the closure film 116 formed inside the lid-like part 112. A negative slit 117 is formed at the center. The small hole 115 is formed with a diameter smaller than the diameter of the sheath of the treatment instrument to be inserted, and the slit 117 is formed longer than the diameter of the sheath.
[0014]
With such a configuration, the slit 117 that is normally closed is pushed open by a treatment instrument (not shown) inserted into the treatment instrument insertion port 102, and the small hole 115 opens the sheath of the treatment instrument to be inserted. It adheres to the outer surface of the sheath so as to be elastically tightened, and contributes to prevention of leakage when the treatment instrument is inserted.
[0015]
FIG. 2 shows an apparatus for detecting leakage of the forceps plug 110. The forceps plug connection member 2 is airtightly connectable to the proximal end side of the forceps plug 110, and an air supply device 50 that sends out pressurized gas. The air supply device connection member 2 that is airtightly connected to the air cap 51 is connected in communication by a flexible tube 3 or the like.
[0016]
For example, the forceps plug connecting member 2 may have the same shape as the treatment instrument insertion port 102 of the endoscope 100, and the flexible tube 3 is formed of a tetrafluoroethylene resin tube, a silicon tube, or the like. .
[0017]
The air supply device 50 may be anything as long as it sends out a pressurized gas having a pressure suitable for the leakage inspection of the forceps plug 110, and the air supply device incorporated in the endoscope light source device can be used as it is. it can.
[0018]
Reference numeral 20 denotes a leak detection adapter that is inserted into the forceps plug 110 at the time of a leak test in order to detect leakage from between the small hole 115 of the forceps plug 110 and the sheath of the treatment instrument. FIG. 1 shows a state where the forceps plug 110 is inserted.
[0019]
The leak detection adapter 20 includes a small hole insertion rod 22 (bar material) that can be inserted into and removed from the small hole 115 from the entrance side of the forceps plug 110, and the small hole insertion rod 22 inserted into the small hole 115. A cap-shaped member 21 (a gripping part / stopper) that contacts the surface of the forceps plug 110 and restricts further insertion of the small hole insertion rod 22 into the forceps plug 110 is formed.
[0020]
The small hole insertion bar 22 is formed in a circular cross section having the same diameter as the sheath diameter (standard diameter) of the treatment instrument inserted through the forceps plug 110, and the cap-shaped member 21 contacts the surface of the forceps plug 110. In the state of contact, the small hole insertion rod 22 elastically pushes and expands the small hole 115, and the small hole 115 is in a state of tightening the small hole insertion rod 22.
[0021]
Therefore, if the small hole 115 is not worn or deformed, the outer peripheral surface of the small hole insertion rod 22 and the small hole 115 are in close contact with each other. On the other hand, when the small hole insertion rod 22 is inserted, the slit 117 is elastically pushed and the peripheral portion remains open.
[0022]
Further, the small hole insertion rod 22 may come out of the small hole 115 unexpectedly due to an internal / external pressure difference (internal pressure> external pressure) with the closing film 114 in which the small hole 115 is formed as a boundary.
[0023]
Therefore, a spherical retaining portion 22b having a diameter larger than that of the small hole insertion rod 22 is formed at the tip of the small hole insertion rod 22 so that the small hole insertion rod 22 is lightly caught on the rear side edge portion of the small hole 115. . However, if a little large force is applied, the retaining portion 22b also passes through the small hole 115.
[0024]
As shown in the front view of FIG. 4, the cap-shaped member 21 has a plurality of ventilation portions 23 formed on the side wall and the end wall, respectively, so that the communication between the forceps plug 110 and the outside can be established. 21 does not disturb.
[0025]
A male screw 22 a is formed on the outer periphery of the base end portion of the small hole insertion bar 22 and is detachably screwed with a female screw 21 a formed at the center position of the cap-shaped member 21.
[0026]
Therefore, if the screwing is loosened, the small hole insertion bar 22 can be converted with respect to the cap-shaped member 21, and as shown in FIG. 5, a plurality of small hole insertion bars 22A, 22B is prepared, and an appropriate small hole insertion rod 22 can be attached and used corresponding to the forceps plug 110 to be inspected.
[0027]
Further, as shown in FIG. 6, if the leak detection adapter 20 is connected to the flexible tube 3 of the leak detection device by a chain 30 or a string, the leak detection adapter 20 does not go missing. It is convenient for management. Both ends of the chain 30 may be engaged with each other by a ring-shaped member 31 such as a so-called double ring.
[0028]
In addition to the leak detection adapter 20 itself, the leak detection device instruction manual 40 and other size leak detection adapters may be connected to the leak detection device of the endoscopic forceps plug through the chain 30 in the same manner. In this case, the chain 30 connecting the instruction manual 40 may be shorter than the other chains so that the instruction manual 40 does not get in the way.
[0029]
With such a configuration, the air supply device connecting member 1 is connected to the air supply device 50, the forceps plug connecting member 2 is connected to the forceps plug 110 into which the leak detection adapter 20 is inserted, and the forceps plug 110 is submerged in water. When the air supply operation of the air supply device 50 is turned on and the closed state between the small hole insertion rod 22 and the small hole 115 is incomplete, the air passing through the small hole 115 is observed as bubbles. Leak detection can be performed. In addition, you may replace with pressurized air and perform a leak test | inspection in air | atmosphere through pressurized water.
[0030]
In addition, the material of the member used for each part of the leak detection device uses tetrafluoroethylene resin, silicon resin, etc. as described above for the tubes so that it can withstand autoclave sterilization, EOG gas sterilization, etc. As the structural material, polysulfone resin, stainless steel, rust-proof metal, or the like may be used.
[0031]
【The invention's effect】
According to the present invention, since the small hole formed in the closing membrane of the forceps plug is elastically tightened by inserting the rod into the forceps plug, the fluid is passed therethrough to the closing membrane. The occurrence of leakage from the formed small hole portion can be detected in advance, so that it is possible to prevent the sewage or the like in the body from leaking through the treatment instrument insertion channel.
