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、このシリンダに送気送水管路が接続されている。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、図8に示す洗浄補助具1が従来から用いられていた。
【0004】
この洗浄補助具1は、送気送水バルブのシリンダ2に挿抜自在に取り付けられる略円柱状の本体3を有し、本体3の外周面で軸方向に直線状溝4が形成されるとともに、直線状溝4に連通した湾曲状貫通孔5がその内部に形成されている。
この洗浄補助具1を利用して洗浄ブラシ6は、球状先端部6Aを先頭にして直線状溝4に挿入され、そして、洗浄ブラシ6の挿入部6Bを押し込むことにより、球状先端部6Aが直線状溝4から湾曲状貫通孔5を介して送気送水管路7に導かれる。これによって、洗浄ブラシ6のブラシ部6Cで送気送水管路7を洗浄することができる。
【0005】
直線状溝4を貫通孔とせず溝とした理由を説明すると、例えば貫通孔にした場合には、その貫通孔と送気送水管路7との距離が必然的に短くなるので、湾曲状貫通孔5の曲率半径が小さくなり、洗浄ブラシ6が湾曲状貫通孔5内で折れ曲がるおそれがある。
【0006】
これに対し、図8の如く直線状溝4とすると、送気送水管路7から溝4を最大限に離すことができるので、湾曲状貫通孔5の曲率半径が最大になり、よって、洗浄ブラシ6を湾曲状貫通孔5で折れ曲がることなくスムーズに送気送水管路7に導くことができるからである。
【0007】
【発明が解決しようとする課題】
しかしながら、図8に示した従来の洗浄補助具1は、洗浄ブラシ6の球状先端部6Aが直線状溝4を通る際に、球状先端部6Aが振れてシリンダ2の開口端2A等に引っ掛かる場合があるので、洗浄ブラシ6をスムーズに送気送水管路7に導くことができな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、洗浄ブラシをスムーズに送気送水管路に導く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、直線状溝がその外周面に形成されるとともに該直線状溝に連通した湾曲状貫通孔がその内部に形成された内視鏡の洗浄補助具であって、洗浄ブラシが前記直線状溝と湾曲状貫通孔とを通過して前記シリンダに接続された送気送水管路に導かれる内視鏡の洗浄補助具において、前記洗浄補助具の頭部にはガイド部材が設けられ、該ガイド部材は球体であるとともに、前記洗浄ブラシが当接されて洗浄ブラシを前記直線状溝から前記湾曲状貫通孔に案内することを特徴としている。
【0010】
本発明は、洗浄補助具の頭部にガイド部材を設けたことを特徴としている。このガイド部材に、洗浄ブラシの挿入部を押圧当接させて洗浄ブラシの先端部を直線状溝に挿入していくと、洗浄ブラシの先端部は、直線状溝の溝底面に摺接された状態で湾曲状貫通孔に案内される。よって、ガイド部材を設けた洗浄補助具を使用することにより、洗浄ブラシをスムーズに送気送水管路に導くことができる。
【0011】
ガイド部材は球体で構成されている。洗浄ブラシの挿入量に従って洗浄ブラシの挿入角度は変化するが、ガイド部材を球体にすると、挿入角度が変化してもガイド部材と洗浄ブラシの挿入部との接触面積は変化しないので、洗浄ブラシを一定の操作感で挿入することができる。
【0012】
【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。
【0013】
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。
【0014】
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。
【0015】
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。
【0016】
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。
【0017】
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。
【0018】
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5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。
【0019】
この洗浄補助具50は図5に示すように、円柱状に形成された本体54及びリング状に形成されたホルダ56等から構成される。ホルダ56は、シリンダ42の上端部に形成された管部43に嵌合されることによりシリンダ42に取り付けられ、このホルダ56内に本体54が嵌挿されることにより、本体54がシリンダ42の所定の位置まで挿入される。
【0020】
本体54には、図4の如く洗浄ブラシの挿入路58、60、62が形成され、本体54をシリンダ42に対して位置決めした時に挿入路58、60、62が給気管24、給水管26、送気管44、又は送水管46に連通されるようになっている。ここでは、給水管26に連通される挿入路58について説明する。
【0021】
挿入路58は図5の如く、直線状溝64と湾曲状貫通孔66とから形成されている。直線状溝64は、本体54の頭部54Aから下方に向けて形成されるとともに、本体54の外周面で軸方向に形成されている。また、湾曲状貫通孔66は、直線状溝64の下端部で連通されるとともに、本体54の内部に向けて形成され、その下端部が、シリンダ42に開口された給水管用ポート68に連通される。したがって、洗浄補助具50の直線状溝64に洗浄ブラシ52を挿入していくと、洗浄ブラシ52は、直線状溝64から湾曲状貫通孔66を介して給水管26に導かれる。
【0022】
ところで、実施の形態の洗浄補助具50には、本体54の頭部54Aに、ねじ棒68と一体形成された球状ガイド部材70が設けられている。ガイド部材70は、ねじ棒68を本体54の頭部54Aの中心部に形成されたねじ穴72に螺合させることにより、本体54の頭部54Aの中心から突出配置されている。
【0023】
また、ガイド部材70は、本体54の中心軸Pから直線状溝64の溝底面65までの距離rよりも長い半径Rの球体である。
【0024】
このようなガイド部材70の表面に、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を直線状溝64の溝底面65に押圧させた状態で洗浄ブラシ52を直線状溝64に挿入していくと、ガイド部材70の表面がガイドとなって、洗浄ブラシ52の球状先端部53が直線状溝64の溝底面65に摺接された状態で直線状溝64を図5〜図7の如く挿入されていく。そして、洗浄ブラシ52の球状先端部53が、途中で引っ掛かることなく、スムーズに湾曲状貫通孔66に導かれる。
【0025】
したがって、ガイド部材70を設けた洗浄補助具50を使用することにより、洗浄ブラシ52をスムーズに給水管26に導くことができる。
【0026】
ガイド部材70を球体で構成すると、洗浄ブラシ52の挿入量に従って洗浄ブラシ52の挿入角度が図5〜図7の如くθ1、θ2、θ3(θ1>θ2>θ3)と変化しても、ガイド部材70と挿入部52Aとの接触面積は変化しないので、洗浄ブラシ52を一定の操作感で挿入することができる。
【0028】
【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、洗浄補助具の端部に、洗浄ブラシを直線状溝から湾曲状貫通孔に案内するガイド部材を設けたので、洗浄ブラシをスムーズに送気送水管路に導くことができる。
【0029】
また、本発明は、ガイド部材を球体で構成したので、洗浄ブラシを一定の操作感で挿入することができる。

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 includes a cylinder, a piston, and the like, and an air / water supply pipe line is connected to the cylinder. The air / water supply pipe line needs to be periodically cleaned with a cleaning brush, but recent air / water supply valves are downsized in consideration of operability, so the cleaning brush is supplied from the cylinder to the air / water supply pipe. It is difficult to insert directly into. Therefore, the cleaning aid 1 shown in FIG. 8 has been conventionally used for cleaning the air / water supply pipeline.
[0004]
This cleaning auxiliary tool 1 has a substantially cylindrical main body 3 that is removably attached to a cylinder 2 of an air / water supply valve. A linear groove 4 is formed in the axial direction on the outer peripheral surface of the main body 3, and a straight line. A curved through-hole 5 communicating with the groove 4 is formed therein.
Using this cleaning aid 1, the cleaning brush 6 is inserted into the linear groove 4 with the spherical tip portion 6A at the head, and the insertion portion 6B of the cleaning brush 6 is pushed in so that the spherical tip portion 6A is straight. From the groove 4 to the air / water supply conduit 7 through the curved through hole 5. As a result, the air / water supply conduit 7 can be cleaned with the brush portion 6 </ b> C of the cleaning brush 6.
[0005]
The reason why the straight groove 4 is not a through hole but a groove will be described. For example, in the case of a through hole, the distance between the through hole and the air / water supply conduit 7 is inevitably shortened. The radius of curvature of the hole 5 becomes small, and the cleaning brush 6 may be bent in the curved through-hole 5.
[0006]
On the other hand, when the linear groove 4 is used as shown in FIG. 8, the groove 4 can be maximally separated from the air / water supply conduit 7, so that the radius of curvature of the curved through-hole 5 is maximized, and thus the cleaning is performed. This is because the brush 6 can be smoothly guided to the air / water supply conduit 7 without being bent at the curved through-hole 5.
[0007]
[Problems to be solved by the invention]
However, in the conventional cleaning aid 1 shown in FIG. 8, when the spherical tip 6A of the cleaning brush 6 passes through the linear groove 4, the spherical tip 6A swings and is caught on the open end 2A of the cylinder 2, etc. Therefore, there is a drawback that the cleaning brush 6 cannot be smoothly guided to the air / water supply conduit 7.
[0008]
This invention is made | formed in view of such a situation, and it aims at providing the washing | cleaning auxiliary tool of the endoscope which can guide a washing | cleaning brush to an air supply / water supply pipe line smoothly.
[0009]
[Means for Solving the Problems]
In order to achieve the above object, the present invention is removably attached to a cylinder of an air / water supply valve provided in a hand operation portion of an endoscope, and a linear groove is formed on an outer peripheral surface thereof. An endoscope cleaning aid having a curved through hole communicating with a groove, and having a cleaning brush connected to the cylinder through the linear groove and the curved through hole In the endoscope cleaning aid guided to the air / water supply conduit, a guide member is provided on the head of the cleaning aid, the guide member is a sphere, and the cleaning brush is brought into contact with the cleaning aid. The brush is guided from the linear groove to the curved through hole.
[0010]
The present invention is characterized in that a guide member is provided on the head of the cleaning aid. When the tip of the cleaning brush is inserted into the linear groove by pressing the cleaning brush insertion portion against the guide member, the tip of the cleaning brush is brought into sliding contact with the groove bottom surface of the linear groove. In the state, it is guided to the curved through hole. Therefore, by using the cleaning aid provided with the guide member, the cleaning brush can be smoothly guided to the air / water supply conduit.
[0011]
The guide member is composed of a sphere. The insertion angle of the cleaning brush changes according to the insertion amount of the cleaning brush, but if the guide member is a sphere, the contact area between the guide member and the insertion portion of the cleaning brush does not change even if the insertion angle changes. It can be inserted with a certain operational feeling.
