Abstract
Description
本発明は、可撓ブラシ線条体を用いる内視鏡の管路洗浄装置及び管路洗浄方法に関する。 The present invention relates to an endoscope pipe cleaning device and a pipe cleaning method using a flexible brush filament.
内視鏡内部には、処置具挿通チャンネルや吸引管路等の管路が設けられている。各種管路は、被検者の体液や薬液等により汚染されるため、内視鏡使用後にブラッシング洗浄を行ない、清潔に保つ必要がある。従来のブラッシング洗浄では、洗浄ブラシを管路の一端部から他端部に挿通させた後、挿入方向に対して逆方向に手で引き抜く作業を何度も繰り返すことで、管路内壁を何回も洗浄ブラシで擦って汚物を除去している。また最近では、洗浄ブラシの挿通回数を減らすため、従来の洗浄ブラシに替えて、図8に示すような可撓ブラシ線条体200を用いることが提案されている。この可撓ブラシ線条体200は、可撓軸210と、該可撓軸210の一端側に間隔をあけて設けた複数のブラシ部220とを備えている(特許文献1参照)。
しかしながら、可撓ブラシ線条体200は管路全長よりも長くなければならず、一般的にその長さ寸法は1m以上となっていることから、手動では可撓ブラシ線条体200を引き抜きづらく、ブラッシング洗浄に時間及び手間が掛かっていた。 However, the flexible brush linear body 200 must be longer than the entire length of the conduit, and generally has a length dimension of 1 m or more, so it is difficult to manually pull out the flexible brush linear body 200. The brushing cleaning took time and effort.
そこで本出願人は、この課題を解決すべく、電動力を利用して可撓ブラシ線条体を巻き取ることができる洗浄装置を提案し、既に特許出願している(特願2003―041043号)が、この発明にも未だ改善の余地がある。 In order to solve this problem, the present applicant has proposed a cleaning apparatus capable of winding a flexible brush filament using electric force, and has already filed a patent application (Japanese Patent Application No. 2003-010443). However, there is still room for improvement in this invention.

そして、使用者が電動巻取器30の巻取スイッチ320をオンすると、モータドライバ332によって電動モータ331が駆動され、巻取ドラム340が回転し始める。巻取ドラム340が回転すると、該回転により可撓ブラシ線条体20が可撓軸21L側から引っ張られ、交換式巻取装置312内に巻き取られていく。このとき、複数のブラシ部22は、順番に第1吸引管路45aを通過しながら第1吸引管路45aの内壁をブラッシング洗浄する。可撓ブラシ線条体20にはブラシ部22が3ヶ所設けられているので、可撓ブラシ線条体20を1回挿脱させることで、3回ブラッシング洗浄を行なった場合と同様の洗浄効果が得られ、第1吸引管路45aの内壁に付着した汚物を除去できる。複数のブラシ部22をすべて第1吸引管路45aから引き出し、図2に示すように可撓ブラシ線条体20のグリップ部23が交換式巻取装置312のブラシ挿入口312cに当て付いたら巻取作業は完了なので、電動巻取器30の巻取スイッチ320をオフする。 Then, when the user turns on the winding switch 320 of the electric winder 30, the electric motor 331 is driven by the motor driver 332, and the winding drum 340 starts to rotate. When the winding drum 340 rotates, the flexible brush linear body 20 is pulled from the flexible shaft 21 </ b> L side by the rotation and wound into the replaceable winding device 312. At this time, the plurality of brush portions 22 brush the inner wall of the first suction conduit 45a while sequentially passing through the first suction conduit 45a. Since the brush portion 22 is provided in three places on the flexible brush linear body 20, the same cleaning effect as when brushing cleaning is performed three times by inserting and removing the flexible brush linear body 20 once. Thus, the dirt attached to the inner wall of the first suction pipe 45a can be removed. When the plurality of brush portions 22 are all pulled out from the first suction conduit 45a and the grip portion 23 of the flexible brush linear body 20 abuts against the brush insertion port 312c of the replaceable winding device 312 as shown in FIG. Since the winding operation is completed, the winding switch 320 of the electric winder 30 is turned off.
続いて、第2吸引管路45bのブラッシング洗浄を行なう。第2吸引管路45bを洗浄する場合には、先ず、駆動装置311から交換式巻取装置312を取り外し、交換式巻取装置312を廃棄処分する。そして、新しい交換式巻取装置312を駆動装置311に取り付けて、交換式巻取装置312から可撓ブラシ線条体20を引き出し、可撓ブラシ線条体20を吸引シリンダ45cの開口部から第2吸引管路45bに挿入していき、全ブラシ部22と可撓軸21Sをコネクタ部44の吸引口金46から外方へ突出させる(図6の状態)。あるいは、可撓ブラシ線条体20をコネクタ部44の吸引口金46から第2吸引管路45bに挿入していき、全ブラシ部22と可撓軸21Sを吸引シリンダ45cの開口部から外方へ突出させる(不図示)。そして、上述した第1吸引管路45aの場合と同様に、電動巻取器30の巻取スイッチ320をオンして可撓ブラシ線条体20を可撓軸21L側から引き抜き、第2吸引管路45b内を通過する複数のブラシ部22によって第2吸引管路45bの内壁に付着した汚物を除去する。 Subsequently, the second suction pipe 45b is cleaned by brushing. In the case of cleaning the second suction pipe 45b, first, the replaceable winding device 312 is removed from the driving device 311 and the replaceable winding device 312 is discarded. Then, a new replaceable winding device 312 is attached to the drive device 311, the flexible brush linear body 20 is pulled out from the replaceable winding device 312, and the flexible brush linear body 20 is removed from the opening of the suction cylinder 45 c. Then, the brush portion 22 and the flexible shaft 21S are protruded outward from the suction cap 46 of the connector portion 44 (state shown in FIG. 6). Alternatively, the flexible brush linear body 20 is inserted into the second suction pipe 45b from the suction cap 46 of the connector portion 44, and the entire brush portion 22 and the flexible shaft 21S are moved outward from the opening of the suction cylinder 45c. Project (not shown). Then, similarly to the case of the first suction pipe 45a described above, the winding switch 320 of the electric winder 30 is turned on, the flexible brush linear body 20 is pulled out from the flexible shaft 21L side, and the second suction pipe The dirt attached to the inner wall of the second suction pipe 45b is removed by the plurality of brush portions 22 passing through the path 45b.
このように第1吸引管路45aと第2吸引管路45bのブラッシング洗浄が終了したら、交換式巻取装置312を駆動装置311から取り外し、可撓ブラシ線条体20とともに交換式巻取装置312を廃棄処分する。そして、次回のブラッシング洗浄時のために、新しい交換式巻取装置312を駆動装置311に装着する。なお、第2吸引管路45bと第1吸引管路45aの洗浄順は逆であっても差し支えない。 When the brushing cleaning of the first suction pipe 45a and the second suction pipe 45b is completed in this way, the replaceable winding device 312 is removed from the driving device 311 and the replaceable winding device 312 together with the flexible brush linear body 20 is removed. Dispose of. Then, a new replaceable winding device 312 is mounted on the driving device 311 for the next brushing cleaning. The cleaning order of the second suction pipe 45b and the first suction pipe 45a may be reversed.
以上の本実施形態によれば、電動巻取器30によって可撓ブラシ線条体20が巻き取られるので、使用者は電動巻取器30の巻取スイッチ320をオンするだけで可撓ブラシ線条体20を吸引管路45から容易に引き抜くことができ、可撓ブラシ線条体20の引抜作業にかかる手間及び時間が大幅に削減される。 According to the above embodiment, since the flexible brush wire body 20 is wound up by the electric winder 30, the user simply turns on the winding switch 320 of the electric winder 30 so that the flexible brush wire is wound. The strip 20 can be easily pulled out from the suction conduit 45, and the labor and time for pulling out the flexible brush strip 20 can be greatly reduced.
さらに、ブラッシング洗浄作業で使用した交換式巻取装置312と可撓ブラシ線条体20は、駆動装置311から取り外すことにより簡単に廃棄処分することができ、新しい交換式巻取装置312を駆動装置311に取り付けることにより、新しい可撓ブラシ線条体20により内視鏡管路をブラッシングできる。このため、可撓ブラシ線条体20を洗浄することなく、ブラッシング洗浄作業を衛生的に行なえる。
また本実施形態では、複数のブラシ部22を備えた可撓ブラシ線条体20を用いるので、1回のブラシ挿脱作業でブラシ部22の数に等しい回数のブラッシング洗浄を行った場合と同じ洗浄効果が得られる。
Furthermore, the replaceable winding device 312 and the flexible brush linear body 20 used in the brushing cleaning operation can be easily disposed of by being removed from the driving device 311, and the new replaceable winding device 312 can be disposed of. By attaching to 311, the endoscope conduit can be brushed by the new flexible brush filament 20. For this reason, the brushing cleaning operation can be performed in a sanitary manner without cleaning the flexible brush filament 20.
Moreover, in this embodiment, since the flexible brush linear body 20 provided with the several brush part 22 is used, it is the same as the case where the brushing washing | cleaning of the number of times equal to the number of the brush parts 22 is performed by one brush insertion / removal operation | work. A cleaning effect is obtained.
本実施形態では上記可撓ブラシ線条体20による第1吸引管路45a及び第2吸引管路45bの洗浄作業を1回としたが、それぞれの洗浄作業を複数回実行してもよい。複数回実行する場合は、1回の洗浄作業が終わるごとに、交換式巻取装置312を可撓ブラシ線条体20とともに駆動装置311から取り外して廃棄処分とし、次の洗浄作業では新しい交換式巻取装置312を駆動装置311に取り付けて、新しい可撓ブラシ線条体20によって第1吸引管路45aと第2吸引管路45bの洗浄作業を行う。 In the present embodiment, the cleaning operation of the first suction conduit 45a and the second suction conduit 45b by the flexible brush linear body 20 is performed once, but each cleaning operation may be performed a plurality of times. When performing a plurality of times, each time the cleaning operation is completed, the replaceable winding device 312 is removed from the drive device 311 together with the flexible brush linear body 20 and discarded, and a new replaceable device is used in the next cleaning operation. The winding device 312 is attached to the drive device 311, and the first suction conduit 45 a and the second suction conduit 45 b are cleaned by the new flexible brush linear body 20.
なお、可撓ブラシ線条体20と巻取用線条体24の結合態様は図7に示すものであってもよい。この態様では、巻取用線条体24のブラシ取付部28に、巻取用線条体24の内部空間と外部とを連通する係合穴29を形成し、かつ、可撓ブラシ線条体20の他端部に、係合部21bと可撓軸21Lとに跨るすり割り21cを設けて、2つに分割された係合部21bを互いに接離する方向に弾性変形可能としている。可撓ブラシ線条体20の両係合部21bを、互いに接近するように弾性変形させながら係合穴29に挿通させ、両係合部21aが係合穴29を貫通すると、図7(b)に示すように、巻取用線条体24の内部において両係合部21aが弾性復帰して係合穴29から抜け止めされ、可撓ブラシ線条体20と巻取用線条体24が結合される。
また、巻取用線条体24を用いずに、可撓ブラシ線条体20の他端部を嵌合溝340dに直接嵌合固定してもよい。
In addition, the coupling aspect of the flexible brush linear body 20 and the winding linear body 24 may be as shown in FIG. In this aspect, the brush mounting portion 28 of the winding linear body 24 is formed with an engagement hole 29 that allows the internal space of the winding linear body 24 to communicate with the outside, and the flexible brush linear body is formed. A slit 21c straddling the engaging portion 21b and the flexible shaft 21L is provided at the other end portion of the 20, so that the two divided engaging portions 21b can be elastically deformed in a direction in which they are brought into contact with and separated from each other. When both engaging portions 21b of the flexible brush linear body 20 are inserted into the engaging holes 29 while being elastically deformed so as to approach each other, and both engaging portions 21a penetrate the engaging holes 29, FIG. ), Both the engaging portions 21a are elastically restored in the inside of the winding linear body 24 and are prevented from coming off from the engaging holes 29, so that the flexible brush linear body 20 and the winding linear body 24 are recovered. Are combined.
Further, the other end portion of the flexible brush linear body 20 may be directly fitted and fixed in the fitting groove 340d without using the winding linear body 24.
さらに、電動巻取器30の代わりにゼンマイ式巻取器(不図示)によって可撓ブラシ線条体20を内視鏡管路から引き抜くことも可能である。ゼンマイ式巻取器の構成としては、例えば、駆動装置311から巻取スイッチ320、電動モータ331、モータドライバ332、及びバッテリ333を取り外し、代わりに、巻き上げ状態から解放状態に移行するときに発生する力により回転体331b(巻取ドラム340)に回転力を付与するゼンマイ(駆動源)と、このゼンマイを巻き上げる手動式巻上機構と、巻き上げたゼンマイを解放状態に移行させる解放スイッチと、を駆動装置311に設けたものが考えられ、このようなゼンマイ式巻取器を用いても、電動巻取器30を用いる場合と同様の効果が得られる。 Furthermore, it is also possible to pull out the flexible brush filament 20 from the endoscope line by a spring type winder (not shown) instead of the electric winder 30. The configuration of the mainspring winder occurs, for example, when the winding switch 320, the electric motor 331, the motor driver 332, and the battery 333 are removed from the driving device 311, and instead, the winding state is changed to the release state. Driving a spring (drive source) that applies a rotational force to the rotating body 331b (winding drum 340) by force, a manual hoisting mechanism that winds up the spring, and a release switch that shifts the wound spring to a released state An apparatus provided in the apparatus 311 can be considered, and even when such a spring type winder is used, the same effect as that obtained when the electric winder 30 is used can be obtained.
以上では、吸引管路45をブラッシング洗浄する実施形態について説明したが、本管路洗浄装置10は、処置具挿通チャンネルや副送水管路など内視鏡内部に設けられた各種管路に対しても使用することができる。 In the above description, the embodiment for brushing and cleaning the suction pipe 45 has been described.
