Description

【0001】
【発明の属する技術分野】
本発明は内視鏡の洗浄補助具に係り、特に内視鏡手元操作部に設けられた送気送水バルブのシリンダに挿入されて、このシリンダに接続されている送気送水管路に洗浄ブラシを導くための洗浄補助具に関する。
【0002】
【従来の技術】
医療用の内視鏡は、手元操作部に送気送水バルブが取り付けられ、送気送水バルブを術者の指で操作することにより、空気と水とを切り換えて体腔内に供給するように構成されている。
【0003】
送気送水バルブは、シリンダ及びピストン等から構成され、このシリンダに給気管、給水管、送気管、及び送水管からなる4本の送気送水管路が接続されている。これらの送気送水管路は、定期的に洗浄ブラシで洗浄する必要があるが、最近の送気送水バルブは操作性を考慮して小型化されているので、前記シリンダから洗浄ブラシを送気送水管路に直接挿入することは難しい。そこで、送気送水管路の洗浄時には、特開平5−228107号公報等に開示された洗浄補助具が従来から用いられていた。
【0004】
前記洗浄補助具は、送気送水バルブのシリンダに挿抜自在に取り付けられる略円柱状の本体を有し、この本体にブラシ案内路が形成されている。この洗浄補助具を利用して洗浄ブラシは、ブラシ部を先頭にしてブラシ案内路に挿入され、洗浄ブラシを押し込むことにより、ブラシ部が送気送水管路に導かれる。これによって、ブラシ部で送気送水管路を洗浄することができる。
【0005】
ところで、最近の内視鏡手元操作部は、操作性を向上させるために小型軽量化が図られており、これに伴い送気送水バルブも必要最小限の大きさに作られている。したがって、送気送水バルブのシリンダに挿入される洗浄補助具も同様に小型になり、小型の洗浄補助具に、前記4本の送気送水管路に対応する4本のブラシ案内路を形成することは困難である。
【0006】
このような背景によって、従来の洗浄補助具は、例えば送気管路用と送水管路用の2本のブラシ案内路が形成された洗浄補助具と、給気管路用と給水管路用の2本のブラシ案内路が形成された洗浄補助具とを用意して、洗浄する管路に応じて二種類の洗浄補助具を使い分けていた。
【0007】
【発明が解決しようとする課題】
しかしながら、前記従来の洗浄補助具は、洗浄する管路に応じて二種類の洗浄補助具を使い分けなければならないので、送気送水管路の洗浄作業性が悪いという欠点があった。
【0008】
本発明は、このような事情に鑑みてなされたもので、一つの洗浄補助具で全ての送気送水管路を洗浄することができる内視鏡の洗浄補助具を提供することを目的とする。
【0009】
【課題を解決するための手段】
本発明は、前記目的を達成するために、内視鏡の手元操作部に設けられた送気送水バルブのシリンダに挿抜自在に取り付けられ、該シリンダに接続された複数本の送気送水管路に洗浄ブラシを案内するためのブラシ案内路が形成された内視鏡の洗浄補助具において、前記洗浄補助具の前記ブラシ案内路は、前記送気送水管路の本数よりも少ない本数で形成され、該洗浄補助具を前記シリンダに挿入した状態で移動させることにより、ブラシ案内路のうち少なくとも1本のブラシ案内路が2本以上の送気送水管路に連通可能であり、前記洗浄補助具には、複数本のブラシ案内路が形成されるとともに、これらのブラシ案内路のうち前記送気送水管路に連通されていないブラシ案内路を閉塞する閉塞部材が設けられていることを特徴としている。
【0010】
発明によれば、洗浄補助具をシリンダに挿入した状態で挿入方向又は回転方向に所定量移動させると、ブラシ案内路のうち少なくとも1本のブラシ案内路が、2本以上の送気送水管路に連通される。すなわち、少なくとも1本のブラシ案内路を、2本以上の送気送水管路に洗浄ブラシを導くブラシ案内路として使用したので、一つの洗浄補助具で全ての送気送水管路を洗浄することが可能になる。
【0011】
発明によれば、複数本のブラシ案内路のうち、送気送水管路に連通されていないブラシ案内路を閉塞する閉塞部材を設けたので、送気送水管路に連通されていないブラシ案内路に洗浄ブラシを挿入するという誤挿入を防止できる。また、閉塞部材の切換動作に連動して、洗浄補助具の挿入又は回転方向の移動を規制及び規制解除することが好ましい。
【0012】
発明は、送気送水管路が4本形成されたシリンダを対象とし、ブラシ案内路が3本形成された洗浄補助具を対象としている。この洗浄補助具によれば、3本のブラシ案内路のうち1本のブラシ案内路を、2本の送気送水管路の間で切り換える。
【0013】
【発明の実施の形態】
以下添付図面に従って本発明に係る内視鏡の洗浄補助具の好ましい実施の形態を詳述する。
【0014】
図1は、内視鏡手元操作部10の外観を示す斜視図であり、図2は手元操作部10の断面図である。
【0015】
図1、図2に示す手元操作部10の本体ケース12の上部には、送気送水バルブを構成するボタン14が設けられ、ボタン14に隣接して吸引ボタン16、及びシャッタボタン18が並設されている。また、本体ケース12の後端部には図1に示すように、接眼部20が設けられている。更に、本体ケース12の下部にはコネクタ22が連結され、コネクタ22には連結チューブ30が連結されている。この連結チューブ30内に図2に示す給気管24、給水管26、吸引管28、及び不図示のライトガイドケーブル等が収納されている。なお、図1の符号32は、鉗子等の処置具が挿入される鉗子孔であり、符号34は、挿入部40の不図示の湾曲部を湾曲操作するアングルノブである。
【0016】
図2に示す吸引管28は、吸引ボタン16側のシリンダ36に接続され、シリンダ36には吸引チューブ38が接続されている。吸引チューブ38は、図1に示す挿入部40に挿通され、挿入部40の先端に設けられた不図示の先端硬質部の吸引口に接続されている。また、図2のシリンダ36には、吸引管28と吸引チューブ38とを連通/遮断させる不図示のピストンが嵌挿され、このピストンの上端部に吸引ボタン16が取り付けられている。吸引ボタン16又はピストンは、吸引管28と吸引チューブ38とを遮断させる方向に、不図示の付勢部材によって付勢されている。この付勢部材の付勢力に抗して吸引ボタン16が押動操作されることにより、吸引管28と吸引チューブ38とが連通される。これによって、体腔内の汚物等が先端硬質部の吸引口から吸引され、吸引チューブ38及び吸引管28を介して手元操作部10の外部に排出される。
【0017】
給気管24、及び給水管26の各々の先端部は、送気送水バルブを構成するシリンダ42の所定の位置に接続される。また、シリンダ42には、送気管44及び送水管46の各々の基端部が所定の位置に接続されている。給気管24の基端部は、不図示の空気供給装置に接続され、この空気供給装置が駆動されることにより、空気が給気管24を介してシリンダ42内に供給される。この状態で、ボタン14に形成された空気リーク孔15を術者の指で閉塞すると、シリンダ42内に供給された前記空気が送気管44に供給される。
【0018】
給水管26の基端部は、不図示の給水タンクに接続されている。ボタン14に連結された不図示のピストンをシリンダ42内で押下操作すると、給気管24が閉塞され、給気管24に流れていた空気が給水タンクに供給される。これによって、給水タンク内の内圧が高まり、給水タンク内の水が給水管26を介してシリンダ42内に供給され、そして、送水管46に供給される。
【0019】
図3に示す洗浄補助具50は、図2のシリンダ42に接続されている給気管24、給水管26、送気管44、及び送水管46に図7に示す洗浄ブラシ52を導くためにシリンダ42に挿入されるものである。
【0020】
この洗浄補助具50は図6〜図10に示すように、円柱状に形成された本体54、リング状に形成されたホルダ56、及び図4〜図6の如く平板状に形成された閉塞部材58等から構成される。
【0021】
本体54には、図4〜図10の如く洗浄ブラシ52のブラシ案内路60、62、64が本体54の軸方向に形成されている。また、本体54は、不図示の位置決め部材を介してホルダ56に軸方向に移動自在に装着され、また、ホルダ56は、図8の如くホルダ56の下部に形成された位置決め用凸部66を、シリンダ42の上部に形成された位置決め用凹部68に係合されることにより、シリンダ42に位置決めされる。これにより、本体54がホルダ56を介してシリンダ42に位置決めされ、本体54の頭部55がホルダ56から突出した図7の初期位置において、本体54のブラシ案内路60が給水管26に連通され、また、頭部55を押し込んだ図9の押込位置において、ブラシ案内路60が給気管24に連通されるとともに、図10の如くブラシ案内路62が送気管44に連通され、そして、ブラシ案内路64が送水管46に連通されるように位置決めされる。
【0022】
一方、閉塞部材58は図4〜図6に示すように、ホルダ56の軸方向に対して直交方向に形成された溝70に貫通配置されるとともに、本体54の軸方向に対して直交方向に形成された溝72に、その摺動面59が摺動自在に設けられている。この溝72によって、ブラシ案内路62、64は上下に分断されている。
【0023】
また、閉塞部材58は、その表面に長孔72が形成され、この長孔72に、ホルダ56の溝70に設けられた一対のガイドピン74、74が係合されている。
これにより、閉塞部材58は、溝70、72に沿って図4の位置と図5の位置との間で往復移動自在に配置されている。
【0024】
更に、閉塞部材58の摺動面59の略中央部には、矩形状の切欠部76が形成されている。この切欠部76は、閉塞部材58が図5の位置に移動された時に、ブラシ案内路62、64を露出させるもので、これにより、溝72で分断された上下のブラシ案内路62、64を溝72を介して各々連通させることができる。
すなわち、洗浄ブラシ52をブラシ案内路62、64に挿通することができる。
また、切欠部76は、閉塞部材58が図4の位置に移動された時に、ブラシ案内路62、64を閉塞させるもので、これにより、ブラシ案内路62、64に対する洗浄ブラシ52の挿入が阻止される。
【0025】
更に、溝72には、図6に示すように閉塞部材58の逃げ溝78が本体54の軸方向に形成されている。したがって、図5、図6に示した閉塞部材58の位置において、本体54を図6の下方向に押し込むと、逃げ溝78に隣接して形成された出っ張り部80が切欠部76を通過するので、本体54をシリンダ42の奥まで押し込むことができる。このように本体54が押し込まれると、本体54は図9、図10に示した押込位置に位置される。これとは逆に、図4、図7、図8に示した閉塞部材58の位置において、本体54を下方に押し込んでも、出っ張り部80の下方に切欠部76が位置していないので、本体54を押し込むことはできない。
【0026】
本体54の頭部55には、ねじ棒82と一体形成された球状ガイド部材84が設けられている。このガイド部材84は、ねじ棒82を本体54の頭部55の中心部に形成されたねじ穴86に螺合させることにより、本体54の頭部55の中心から突出配置される。
【0027】
このようなガイド部材84の表面に、図7の如く洗浄ブラシ52の挿入部52Aを当接させるとともに、洗浄ブラシ52の球状先端部53をブラシ案内路60に押圧させた状態で洗浄ブラシ52をブラシ案内路60に挿入していくと、ガイド部材84の表面がガイドとなって、洗浄ブラシ52がブラシ案内路60にスムーズに挿入されていく。
【0028】
次に、前記の如く構成された洗浄補助具50の作用について説明する。
【0029】
まず、閉塞部材58を図4の位置に位置決めした状態で、すなわち、ブラシ案内路62、64を閉塞部材58で閉塞した状態で、洗浄補助具50をシリンダ42に装着する。これにより、洗浄補助具50は初期位置に位置し、本体54のブラシ案内路60が図7の如く給水管26と連通するので、ブラシ案内路60を介して給水管26に洗浄ブラシ52を挿入することができる。この時、他のブラシ案内路62、64は、図8の如く送気管44や送水管46に連通されておらず、また、ブラシ案内路62、64は閉塞部材58によって図4の如く閉塞され、洗浄ブラシ52の挿入が阻止されているので、ブラシ案内路62、64に対する洗浄ブラシ52の誤挿入が防止されている。
【0030】
次に、ブラシ案内路60を給気管24に連通させ、ブラシ案内路62を送気管44に連通させ、ブラシ案内路64を送水管46に連通させる場合には、まず、閉塞部材58を図4の位置から図5の位置にスライドさせて、上下のブラシ案内路62、64を各々連通させるとともに、本体54の押し込みを可能にする。
【0031】
次に、ガイド部材84を指で摘んで本体54を図9、図10の押込位置まで押し込む。これにより、本体54のブラシ案内路60が図9の如く給気管24と連通するので、ブラシ案内路60を介して給気管24に洗浄ブラシ52を挿入することができる。また、本体54のブラシ案内路62が図10の如く送気管44と連通し、ブラシ案内路64が送水管46と連通するので、ブラシ案内路62を介して送気管44に洗浄ブラシ52を挿入することができるとともに、ブラシ案内路64を介して送水管46に洗浄ブラシ52を挿入することができる。
【0032】
したがって、実施の形態の洗浄補助具50によれば、洗浄補助具50をシリンダ42に挿入した状態で挿入方向に所定量移動させると、ブラシ案内路60が、給水管26と給気管24との間で切り換えられる。すなわち、1本のブラシ案内路60を、給水管26と給気管24に洗浄ブラシ52を導くブラシ案内路として使用したので、3本のブラシ案内路60、62、64が形成された洗浄補助具50で、4本の送気送水管路24、26、44、46を洗浄することができる。
【0033】
なお、実施の形態では、ブラシ案内路60、62、64が3本形成された洗浄補助具50について説明したが、ブラシ案内路の本数はこれに限定されず、また、シリンダ42に接続される送気送水管路24、26、44、46の本数もこの限りではない。要するに、1本のブラシ案内路を2本以上の送気送水管路に連通させるように構成すればよい。
【0034】
更に、実施の形態の洗浄補助具50は、本体54を軸方向に押し込んで2本の送気送水管路を切り換えるようにしたが、シリンダ42に対する送気送水管路の取付位置によっては本体54を回転方向に回動させて2本の送気送水管路を切り換えることもできる。
【0035】
【発明の効果】
以上説明したように本発明に係る内視鏡の洗浄補助具によれば、洗浄補助具をシリンダに挿入した状態で移動させると、ブラシ案内路のうち少なくとも1本のブラシ案内路が、2本以上の送気送水管路に連通可能なので、一つの洗浄補助具で全ての送気送水管路を洗浄することが可能になる。
【0036】
また、本発明によれば、複数本のブラシ案内路のうち、送気送水管路に連通されていないブラシ案内路を閉塞する閉塞部材を設けたので、送気送水管路に連通されていないブラシ案内路に洗浄ブラシを挿入する誤挿入を防止できる。

BACKGROUND OF THE INVENTION
The present invention relates to an endoscope cleaning aid, and in particular, is inserted into a cylinder of an air / water supply valve provided in an endoscope hand operation section, and a cleaning brush is connected to an air / water supply conduit connected to the cylinder. The present invention relates to a cleaning aid for guiding
[0002]
[Prior art]
The medical endoscope has an air / water supply valve attached to the hand control unit, and is configured to supply air and water into the body cavity by operating the air / water supply valve with the operator's fingers. Has been.
[0003]
The air / water supply valve is constituted by a cylinder, a piston, and the like, and four air / water supply pipes including an air supply pipe, a water supply pipe, an air supply pipe, and a water supply pipe are connected to the cylinder. These air / water supply pipelines need to be regularly cleaned with a cleaning brush. However, recent air / water supply valves are downsized in consideration of operability. It is difficult to insert directly into the water pipe. Therefore, a cleaning aid disclosed in JP-A-5-228107 has been conventionally used for cleaning the air / water supply pipeline.
[0004]
The cleaning aid has a substantially cylindrical main body that is detachably attached to a cylinder of an air / water supply valve, and a brush guide path is formed in the main body. Using this cleaning aid, the cleaning brush is inserted into the brush guide passage with the brush portion at the top, and the brush portion is guided to the air / water supply conduit by pushing the cleaning brush. Thereby, the air / water supply conduit can be cleaned with the brush portion.
[0005]
By the way, recent endoscope hand control units have been reduced in size and weight in order to improve operability, and along with this, air / water supply valves are also made to the minimum necessary size. Accordingly, the cleaning aid inserted into the cylinder of the air / water supply valve is similarly reduced in size, and four brush guide paths corresponding to the four air / water supply conduits are formed in the small cleaning aid. It is difficult.
[0006]
Due to such a background, the conventional cleaning auxiliary tool includes, for example, a cleaning auxiliary tool in which two brush guide paths for an air supply line and a water supply line are formed, an air supply line and a water supply line 2 A cleaning auxiliary tool having a brush guide path formed therein was prepared, and two types of cleaning auxiliary tools were properly used according to the pipe line to be cleaned.
[0007]
[Problems to be solved by the invention]
However, the conventional cleaning aid has the disadvantage that the cleaning workability of the air / water supply conduit is poor because two types of cleaning aids must be used properly according to the conduit to be cleaned.
[0008]
The present invention has been made in view of such circumstances, and an object of the present invention is to provide an endoscope cleaning aid that can clean all the air / water supply conduits with a single cleaning aid. .
[0009]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a plurality of air / water supply conduits that are detachably attached to and connected to a cylinder of an air / water supply valve provided in a hand operating portion of an endoscope. In the endoscope cleaning auxiliary tool in which the brush guide path for guiding the cleaning brush is formed, the brush guide path of the cleaning auxiliary tool is formed with a number smaller than the number of the air / water supply conduits. by moving the cleaning aid in the state of being inserted into the cylinder, Ri communicatively der at least one gas-feeding and water-feeding pipeline brush guide passage is more than two of the brush guide passage, said cleaning adjunct The tool is formed with a plurality of brush guide paths, and is provided with a closing member that closes a brush guide path that is not communicated with the air / water supply conduit among the brush guide paths. It is said.
[0010]
According to the present invention, when the cleaning aid is inserted into the cylinder and moved by a predetermined amount in the insertion direction or the rotation direction, at least one of the brush guide paths has two or more air / water supply pipes. Connected to the road. That is, since at least one brush guide path is used as a brush guide path that guides the cleaning brush to two or more air / water supply conduits, all the air / water supply conduits are cleaned with one cleaning aid. Is possible.
[0011]
According to the present invention, since the blocking member that closes the brush guide path that is not communicated with the air / water supply conduit among the plurality of brush guide paths is provided, the brush guide that is not communicated with the air / water supply duct Incorrect insertion of a cleaning brush into the road can be prevented. Further, it is preferable to restrict and release the insertion of the cleaning aid or the movement in the rotation direction in conjunction with the switching operation of the closing member.
[0012]
The present invention is directed to a cylinder having four air / water supply pipes and a cleaning aid having three brush guide paths. According to this cleaning aid, one brush guide path among the three brush guide paths is switched between the two air / water supply conduits.
[0013]
