Description

【0001】
【発明の属する技術分野】
この発明は、鉗子チャンネルの入口からの体腔内汚液の飛散を防止するための内視鏡の汚液飛散防止具に関する。
【0002】
【従来の技術】
内視鏡には一般に、処置具類を通すための鉗子チャンネルが挿入部内に挿通されていて、その先端出口は挿入部の先端において開口し、基端入口は操作部において開口している。
【0003】
ただし、そのままでは、体腔内の圧力によって体腔内の汚液が鉗子チャンネル内を通って操作部側の入口開口から噴出し、術者やその周囲を汚染してしまうことになる。
【0004】
そこで、そのような汚液噴出を阻止し、且つ鉗子チャンネルに対する処置具の挿脱を行うことができるように、鉗子チャンネルの入口開口部には、例えばスリットが形成されたゴム弁からなるいわゆる鉗子栓が装着されている。
【0005】
【発明が解決しようとする課題】
しかし、鉗子栓に処置具が通されると、ゴム弁のスリットが押し広げられてスリットの端の方の部分では処置具の外周面との間に隙間ができ、その部分から汚液が噴出する場合が少なくない。特に、コイルパイプをシースとする処置具の場合は、外周面に螺旋状に隙間があるので汚液が噴出し易い。
【0006】
また、シース内に操作ワイヤ等が進退自在に挿通された処置具の場合には、シースと操作ワイヤとの間に隙間があるので、その部分を通って汚液が噴出する場合がある。
【0007】
そのようにして、体腔内汚液が鉗子チャンネルの入口側から噴出すると、術者の顔や手に汚液がかかったり、周囲に飛散して非常に不衛生な状態になってしまう場合があるが、そのような体腔内汚液の噴出を完全に防止するのは困難である。
【0008】
そこで本発明は、鉗子チャンネルの入口から体腔内汚液が外方に飛び散らず、内視鏡検査を衛生的に行うことができる内視鏡の汚液飛散防止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】
上記の目的を達成するため、本発明の内視鏡の汚液飛散防止具は、柔軟性のある吸水性材料からなる汚液吸収部材を内視鏡の操作部の外表面部分に着脱自在に設けて、上記操作部付近に設けられた鉗子チャンネルの入口を覆う状態に上記汚液吸収部材を配置したことを特徴とする。
【0010】
なお、上記汚液吸収部材が上記操作部の外表面に貼着されるようにしてもよく、上記鉗子チャンネルの入口部分が上記操作部から突出していて、その突出部に係合する孔が上記汚液吸収部材に形成されていてもよい。
【0011】
【発明の実施の形態】
図面を参照して本発明の実施の形態を説明する。
図1において、1は内視鏡の操作部であり、その下端部に、体腔内に挿入される挿入部2が連結されている。
【0012】
挿入部2内には、その先端に開口する鉗子チャンネル4が全長にわたって挿通されている。そして、鉗子チャンネル4の基端側は、操作部1の下端部に斜め上方に向けて突設された突出部3の先端に開口形成された処置具挿入口5に連通している。
【0013】
処置具挿入口5のすぐ内側の突出部3内には、通常は閉じていて、処置具挿入口5から鉗子チャンネル4内へ処置具が挿通されたときだけ押し開かれる鉗子栓6が配置されている。
【0014】
操作部1の上半部には、送気送水操作弁7と吸引操作弁8とが前面側に配置され、挿入部2の先端近傍に形成された湾曲部(図示せず)を遠隔的に屈曲操作するための湾曲操作ノブ9が、側面に配置されている。その部分と操作部1の下端部との間は握り部1aになっている。
【0015】
20は内視鏡の汚液飛散防止具であり、図2に示されるように、例えば柔軟性のあるガーゼ等の吸水性材料を折り返して複数枚重ね合わせて形成された汚液吸収部材21の中央部分を、広がらないよいうに糸で縫い合わせてある。
【0016】
その糸23部分に沿った断面を示す図3にも示されるように、糸23で縫い合わされた部分に沿って汚液吸収部材21の表面には、汚液飛散防止具20を操作部1に係止するための、例えば両面粘着テープからなる係止部材22が貼着されている。
【0017】
ただし、図3に示されるように、両面粘着テープ22の操作部1に貼り付けられる側の面には、粘着テープ22に対して容易に剥がれる保護シート25が付けられていて、操作部1に取り付ける直前に剥がすようになっている。
【0018】
このように形成された汚液飛散防止具20は、使用時には、保護シート25を取り外してから、図1に示されるように、係止部材22を操作部1の突出部3のすぐ上の前面側の外表面に貼り付け、処置具挿入口5部分に汚液吸収部材21の半部を被せる。
【0019】
そのようにすることにより、鉗子チャンネル4を通ってきた体腔内の汚液が処置具挿入口5から外へ噴出しても、汚液吸収部材21に吸い取られるので、周囲に飛散したり術者の手や顔にかかったりしない。
【0020】
また、汚液吸収部材21の残りの半部は操作部1の握り部1aに沿わせて、握り部1aと一緒に握るとよい。そのようにすることにより、汚液が手に伝わるのを防止することができると共に、操作部1の保持が滑らなくなって持ち易くなり、また、汚液吸収部材21が安定して保持される。
【0021】
なお、図4に示されるように、汚液吸収部材21の両側の半部が共に処置具挿入口5を覆うように配置してもよい。この場合には、握り部1aを握った術者の手の小指で汚液吸収部材21を軽く押さえて保持することができる。このようにすることにより、処置具挿入口5から漏出する汚液に対する吸水力がより大きくなる。
【0022】
処置具挿入口5から鉗子チャンネル4内に処置具を挿入して使用する際には、図5に示されるように、汚液吸収部材21で処置具100の周囲を囲むようにすれば、周囲への汚液の飛散を防ぐことができる。
【0023】
図6ないし図8は本発明の第2の実施の形態を示しており、係止部材22として一面粘着テープを用いたものである。この実施の形態の係止部材22は、使用前の状態では図7に示されるように折り畳まれている。
【0024】
そして使用時には、先端に形成された非接着性の摘み部26を外方に引っ張ることにより、係止部材22が引き出されて、図8に示されるように操作部1の外表面に貼着することができる。
【0025】
なお図8では、汚液吸収部材21の半部が操作部1の握り部1aに沿わされて握り部1aと一緒に握られているが、第1の実施の形態における図4に示される状態のように、汚液吸収部材21の両側の半部を共に処置具挿入口5に被せてもよい。また、第1の実施の形態における図5に示される状態のように、処置具100使用時には汚液吸収部材21で処置具100の周囲を囲むようにするとよい。
【0026】
図9ないし図13は本発明の第3の実施の形態を示しており、図9におけるXI−XI断面を示す図11に示されるように、汚液吸収部材として吸水性のある布(又は不織布)21aの内側にそれより吸水性の高い物質21b(例えば高分子含水性ポリマー)を配置して、裏面には、図10に示されるように、防水性の布(又は紙)28をあてがったものである。
【0027】
係止部材22としては、図9に示されるように表面側に両面粘着テープが貼り付けられており、使用時には、図12に示されるように、係止部材22が操作部1の突出部3のすぐ上の部分の外表面に貼着される。
【0028】
このようにして、この実施の形態の場合にも、図12に示されるように処置具挿入口5を汚液吸収部材21で覆うことができ、処置具使用時には、図13に示されるように、処置具挿入口5に挿入される処置具100を汚液吸収部材21で上側から包む状態にすることができる。
【0029】
図14及び図15は本発明の第4の実施の形態を示しており、係止部材22として、操作部1の突出部3に係合する孔を汚液吸収部材21に穿設したものである。図14は汚液飛散防止具20の正面図、図15は、孔22に突出部3が通された使用状態である。このように、係止部材22としては、汚液吸収部材21を操作部1に係止することができる手段であれば、どのような手段を用いてもよい。
【0030】
【発明の効果】
本発明によれば、柔軟性のある吸水性材料からなる汚液吸収部材を内視鏡の操作部の外表面部分に着脱自在に設けて鉗子チャンネルの入口を覆う状態に汚液吸収部材を配置したので、鉗子チャンネルの入口から体腔内汚液が外方に飛び散らず、内視鏡検査を衛生的に行うことができる。そして、汚液飛散防止具は、必要に応じて容易に取り付け取り外し及び交換することができる。

TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waste liquid scattering prevention device for an endoscope for preventing waste liquid in a body cavity from scattering from an inlet of a forceps channel.
[0002]
[Prior art]
In general, a forceps channel for passing treatment tools is inserted into the insertion portion of the endoscope, and a distal end outlet of the forceps channel is opened at a distal end of the insertion portion, and a base end entrance is opened at the operation portion.
[0003]
However, as it is, the pressure in the body cavity causes the waste fluid in the body cavity to flow through the forceps channel from the inlet opening on the operation unit side, thereby contaminating the operator and its surroundings.
[0004]
Therefore, the so-called forceps made of, for example, a rubber valve having a slit is formed at the inlet opening of the forceps channel so as to prevent such discharge of the waste fluid and to allow the treatment tool to be inserted into and removed from the forceps channel. A stopper is attached.
[0005]
[Problems to be solved by the invention]
However, when the treatment tool is passed through the forceps plug, the slit of the rubber valve is pushed open and a gap is created between the end of the slit and the outer peripheral surface of the treatment tool, and contaminants are ejected from that part. There are many cases. In particular, in the case of a treatment tool having a coil pipe as a sheath, since there is a spiral gap on the outer peripheral surface, the waste liquid is easily ejected.
[0006]
Further, in the case of a treatment tool in which an operation wire or the like is inserted into the sheath so as to be able to advance and retreat, there is a gap between the sheath and the operation wire.
[0007]
In such a manner, when the intracorporeal waste fluid spouts out from the inlet side of the forceps channel, the waste fluid may be applied to the face or hand of the operator or may be scattered around, resulting in a very unsanitary condition. However, it is difficult to completely prevent such ejection of body fluid.
[0008]
Therefore, an object of the present invention is to provide a waste liquid scattering prevention device for an endoscope in which a waste fluid in a body cavity is not scattered outward from an inlet of a forceps channel and an endoscope inspection can be performed hygienically. .
[0009]
[Means for Solving the Problems]
In order to achieve the above object, a waste liquid scattering prevention device for an endoscope according to the present invention is configured such that a waste liquid absorbing member made of a flexible water-absorbing material is detachably attached to an outer surface portion of an operation section of the endoscope. The waste liquid absorbing member is provided so as to cover an inlet of a forceps channel provided near the operation unit.
[0010]
Note that the waste liquid absorbing member may be attached to an outer surface of the operation unit, and an inlet portion of the forceps channel protrudes from the operation unit, and a hole that engages with the protrusion is the hole. It may be formed on the waste liquid absorbing member.
