Description

【0001】
【発明の属する技術分野】
この発明は、処置具挿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処置具挿通チャンネルが挿入部内に挿通されていて、その処置具出口は挿入部の先端において開口し、処置具挿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処置具挿通チャンネル内を通って操作部側の処置具挿入口から噴出し、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、且つ処置具挿通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、処置具挿入口部分には、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】
図9は、内視鏡の挿入部1を患者の肛門から大腸内に挿入して、腸内の内視鏡検査を行っている状態を示している。処置具挿入口3は操作部2の下端部前側に、斜め上方に向けて突設されている。
【0008】
大腸内に内視鏡を挿入する際には、腸を膨らませるために送気をするので、腸内の圧力が高くなって、腸内の空気がおならのように吹き出す。空気を出さないと患者が大きな苦痛を感じるので、これは避けられない現象であるが、その際に、下剤等に溶けた糞便等が空気と一緒に処置具挿入口3から噴出する。
【0009】
そのようにして、糞便等を含む体腔内汚液が処置具挿入口3から噴出すると、上方に位置する術者の顔や手に汚液がかかったり周囲に飛散すると共に、処置具挿入口3の口元から下方にしたたり落ちてベッドや患者の肌等を汚し、非常に不衛生な状態になってしまう場合がある。
【0010】
そこで本発明は、処置具挿入口から体腔内汚液が周囲に飛び散らず、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。
【0011】
【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、内視鏡の処置具挿入口周辺の上側の外壁面と下側の外壁面とを覆うように内視鏡に対して着脱自在に設けると共に、上記汚液吸収部材に、上記処置具挿入口部分を覆脱自在な自由端部を設けたことを特徴とする。
【0012】
なお、上記汚液吸収部材が、上記内視鏡の処置具挿入口周辺の上側の外壁面を覆うためのものと、下側の外壁面を覆うためのものとに分離して形成されていて、その一方に上記自由端部が設けられていてもよい。
【0013】
また、上記汚液吸収部材が、全体として一繋がりに形成されていてもよい。そして、上記処置具挿入口部分が上記外壁面から突出して形成されており、その突出部が通される孔が上記汚液吸収部材に形成されていてもよい。
【0014】
また、上記汚液吸収部材を上記外壁面に着脱自在に係止するための係止部材が設けられていてもよく、上記係止部材が、環状の一部を切り欠いた断面形状の弾性材によって形成されていて、上記汚液吸収部材を外側から上記外壁面に押圧固定するようになっていてもよい。
【0015】
【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、2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1が連結されている。
【0016】
挿入部1内には、その先端に開口する処置具挿通チャンネル(図示せず)が全長にわたって挿通されている。そして、処置具挿通チャンネルの基端側は、操作部2の下端部前側に斜め上方に向けて突設された突出部4の先端に開口形成された処置具挿入口3に連通している。
【0017】
処置具挿入口3のすぐ内側の突出部4内には、通常は閉じていて、処置具挿入口3から処置具挿通チャンネル内へ処置具が挿通されたときだけ押し開かれる鉗子栓(図示せず)が配置されている。
【0018】
操作部2の下半部には、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10が着脱自在に取り付けられている。
【0019】
汚液吸収部材10は、処置具挿入口3周辺の上側の操作部2の外壁面を覆う上側汚液吸収部材10aと、処置具挿入口3周辺の下側の操作部2の外周面を覆う下側汚液吸収部材10bとが二つに別けて配置されている。
【0020】
上側汚液吸収部材10aと下側汚液吸収部材10bは、共に、処置具挿入口3が配置された操作部2の前面側から左右両側面において、操作部2の外壁面を覆うように取り付けられている。
【0021】
上側汚液吸収部材10aと下側汚液吸収部材10bは、共に、断面形状がC字状でバネ性のある金属又はプラスチックからなる係止部材12によって、操作部2に対して着脱自在に係止されている。
【0022】
図2は、係止部材12によって汚液吸収部材10が操作部2に係止された部分の平面断面を示している。
係止部材12は、操作部2との間に汚液吸収部材10を挟み込むようにして、操作部2の外壁面を外側から弾力的に締め付ける状態に取り付けられる。
【0023】
その結果、汚液吸収部材10が係止部材12によって操作部2の外壁面に外側から押圧固定される。そして、係止部材12を弾性変形させて操作部2の外壁面から取り外せば、汚液吸収部材10を取り外して新しいものと交換することができる。
【0024】
係止部材12の外面には、直径方向に一対の指掛け突起13が突出形成されていて、操作部2に係止部材12を着脱する際に指先を引っ掛け易いようになっている。
【0025】
図1に戻って、上側汚液吸収部材10aは、処置具挿入口3のすぐ上の部分で係止部材12によって操作部2に係止されて、そこからさらに上方に配置されていて、操作部2を握る操作者の手の内側に握り込まれるようになっている。
【0026】
そのようにすることにより、処置具挿入口3から噴出される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2の保持が滑らなくなって持ち易くなる。また、上側汚液吸収部材10a自体の保持も安定したものとなる。
【0027】
一方、下側汚液吸収部材10bは、処置具挿入口3のすぐ下の部分で係止部材12によって操作部2に係止されており、そこから下方にたらして配置されると共に、係止部材12より上方に位置する自由端10cは、処置具挿入口3部分を覆うようにその上に載せられている。
【0028】
したがって、処置具挿通チャンネルを通ってきた体腔内の汚液が処置具挿入口3から外へ噴出しても、そのほとんどは自由端10cにおいて汚液吸収部材10に吸収されるので、周囲に飛散したり術者の手や顔にかかったりしない。
【0029】
そして、処置具挿入口3から上方に撥ね出し或いは染み出す汚液は、上側汚液吸収部材10aによって吸い取られるので、操作部2を握る術者の手などが汚されない。
【0030】
また、処置具挿入口3から下の方へしたたり落ちようとする汚液は、下側汚液吸収部材10bの下半部分によって吸い取られて、それより下に落下しない。したがって、ベッドや患者の肌が汚されない。
【0031】
処置具挿入口3から処置具を挿入する際には、図1に二点鎖線で示されるように、汚液吸収部材10の自由端10cを処置具挿入口3部分から外して、処置具を矢印Aで示されるように処置具挿入口3に挿入すればよい。
【0032】
図3は、本発明の第2の実施の形態を示しており、処置具挿入口3部分を覆うための汚液吸収部材10の自由端10cを、上側汚液吸収部材10a側に設けたものである。この場合にも、処置具を使用する場合には、二点鎖線で示されるように、自由端10cを処置具挿入口3部分から取り外せばよい。
【0033】
図4は、本発明の第3の実施の形態の汚液吸収部材10を示しており、操作部2の突出部4部分を通すための孔11が中央部分に穿設されている。図5は、その汚液吸収部材10が操作部2に取り付けられた使用状態を示しており、汚液吸収部材10の中央部分に穿設された孔11に突出部4が通され、処置具挿入口3の上側と下側の操作部2の外壁面が、一つの汚液吸収部材10によって覆われている。
【0034】
なお、処置具挿入口3部分を覆う汚液吸収部材10の自由端10cは、図5においては上側の自由端が利用されているが、下側の自由端を使用してもよい。また、係止部材12は、処置具挿入口3より上側に一個だけ取り付けられているが、複数取り付けても差し支えない。
【0035】
図6は、本発明の第4の実施の形態を示しており、処置具挿入口3の上側と下側とに分けて配置された汚液吸収部材10a,10bを、一つの係止部材12で係止するようにしたものである。
【0036】
係止部材12の材料や断面形状は、図2に示される第1の実施の形態の場合と同様であるが、上側と下側の両汚液吸収部材10a,10bを同時に押さえられるように、縦方向に長く形成されており、中央部分には突出部4を通すための孔12aが形成されている。13は、突出形成された指掛けである。
【0037】
図7は、本発明の第5の実施の形態の汚液吸収部材10を示しており、操作部2の外壁面に直接貼り付けるための感圧接着剤14を、汚液吸収部材10の裏面側に取り付けたものである。
【0038】
図8は、その汚液吸収部材10が操作部2に取り付けられた状態を示しており、前述の各実施の形態において用いられた係止部材12を使用することなく、上側汚液吸収部材10aと下側汚液吸収部材10bとが、各々感圧接着剤14によって操作部2の外壁面に貼り付けられている。
【0039】
感圧接着剤14としては、いわゆる両面粘着テープ等を用いることができ、内視鏡検査が終了したら、操作部2の表面から引き剥がして、汚液吸収部材10を新しいものと交換することができる。
【0040】
なお、図4と図5に示される第3の実施の形態で用いられたような、全体が一繋がりに形成された汚液吸収部材10を操作部2に係止する手段として、感圧接着剤14を用いてもよい。
【0041】
【発明の効果】
本発明によれば、処置具挿入口から噴出する汚液が、処置具挿入口部分を覆う汚液吸収部材の自由端部分によってまず吸収されて周囲に飛散せず、さらに、そこから上方へ撥ね出し或いは染み出す汚液は汚液吸収部材の上側部分に吸収され、下方にしたたり落ちようとする汚液は汚液吸収部材の下側部分に吸収される。したがって処置具挿入口から体腔内汚液が周囲に飛び散らず、内視鏡検査を衛生的に行うことができる。
【0042】
そして、汚液飛散防止具は、必要に応じて内視鏡に容易に取り付け取り外し及び交換することができる。

BACKGROUND OF THE INVENTION
The present invention relates to an endoscope filth scatter preventive tool for preventing scatter of bodily effluent from a treatment instrument insertion port.
[0002]
[Prior art]
In general, a treatment instrument insertion channel for passing treatment instruments is inserted into an insertion portion of an endoscope, the treatment instrument outlet opens at the distal end of the insertion section, and the treatment instrument insertion port opens at an operation section. ing.
[0003]
However, as it is, the sewage in the body cavity is ejected from the treatment instrument insertion port on the operation unit side through the treatment instrument insertion channel due to the pressure in the body cavity and contaminates the operator and its surroundings.
[0004]
Therefore, in order to prevent such squirt jetting and to allow the treatment instrument to be inserted into and removed from the treatment instrument insertion channel, the treatment instrument insertion port portion is a so-called rubber valve formed with a slit, for example. A forceps plug 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 and widened to create a gap between the end of the slit and the outer peripheral surface of the treatment tool. There are many cases to do. In particular, in the case of a treatment instrument having a coil pipe as a sheath, since there is a spiral gap on the outer peripheral surface, the sewage is easily ejected.
[0006]
Further, in the case of a treatment instrument in which an operation wire or the like is inserted in the sheath so as to be able to advance and retreat, there is a gap between the sheath and the operation wire, so that sewage may be ejected through that portion.
[0007]
FIG. 9 shows a state where the endoscope insertion section 1 is inserted into the large intestine from the patient's anus and the endoscopic examination in the intestine is performed. The treatment instrument insertion port 3 protrudes obliquely upward on the front side of the lower end of the operation unit 2.
[0008]
When an endoscope is inserted into the large intestine, air is supplied to inflate the intestine, so that the pressure in the intestine increases and air in the intestine blows out like a fart. This is an unavoidable phenomenon because the patient feels great pain if the air is not released. At this time, feces and the like dissolved in the laxative and the like are ejected from the treatment instrument insertion port 3 together with the air.
[0009]
In this way, when the in-body cavity semen containing feces or the like is ejected from the treatment instrument insertion port 3, the semen is applied to the operator's face or hand located above or scattered around the treatment tool insertion port 3 May fall or fall from the mouth of the mouth and soil the bed, patient's skin, etc., resulting in a very unsanitary state.
[0010]
SUMMARY OF THE INVENTION An object of the present invention is to provide an endoscope sewage splattering preventive tool that can perform an endoscopic examination in a sanitary manner without spilling the sewage in the body cavity from the treatment tool insertion port.
[0011]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the endoscope anti-sludge scattering device of the present invention has an anti-soil absorbing member made of a flexible water-absorbing material provided on the upper side around the endoscope treatment instrument insertion port. Provided to be detachable from the endoscope so as to cover the wall surface and the lower outer wall surface, and provided with a free end portion that is detachable from the treatment instrument insertion port portion in the sewage absorbing member. Features.
[0012]
In addition, the dirty liquid absorbing member is formed separately for covering the upper outer wall surface around the treatment instrument insertion port of the endoscope and for covering the lower outer wall surface. One of the free ends may be provided with the free end.
[0013]
Moreover, the said waste liquid absorption member may be formed in a continuous as a whole. The treatment instrument insertion port portion may be formed to protrude from the outer wall surface, and a hole through which the protrusion is passed may be formed in the sewage absorbing member.
[0014]
Further, a locking member for detachably locking the sewage absorbing member to the outer wall surface may be provided, and the locking member is an elastic material having a cross-sectional shape in which a part of an annular shape is cut out. The sewage absorbing member may be pressed and fixed to the outer wall surface from the outside.
[0015]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described with reference to the drawings.
In FIG. 1, 2 is an operation part of an endoscope, and an insertion part 1 to be inserted into a body cavity is connected to a lower end part thereof.
[0016]
A treatment instrument insertion channel (not shown) that opens at the distal end of the insertion portion 1 is inserted over the entire length. The proximal end side of the treatment instrument insertion channel communicates with the treatment instrument insertion port 3 that is formed to open at the distal end of the protruding portion 4 that protrudes obliquely upward from the lower end front side of the operation section 2.
[0017]
A forceps plug (not shown) that is normally closed in the protrusion 4 immediately inside the treatment instrument insertion port 3 and is pushed open only when the treatment instrument is inserted from the treatment instrument insertion port 3 into the treatment instrument insertion channel. ) Is arranged.
[0018]
A sewage absorbing member 10 formed by folding a plurality of water-absorbing materials such as flexible gauze, for example, is detachably attached to the lower half of the operation unit 2.
[0019]
The dirty liquid absorbing member 10 covers the outer peripheral surface of the upper dirty liquid absorbing member 10 a that covers the outer wall surface of the upper operation unit 2 around the treatment instrument insertion port 3 and the lower operation unit 2 around the treatment tool insertion port 3. The lower sewage absorbing member 10b is divided into two parts.
[0020]
The upper sewage absorbing member 10a and the lower sewage absorbing member 10b are both attached so as to cover the outer wall surface of the operation unit 2 on the left and right side surfaces from the front side of the operation unit 2 where the treatment instrument insertion port 3 is disposed. It has been.

Both the upper sewage absorbing member 10a and the lower sewage absorbing member 10b are detachably attached to the operation unit 2 by a locking member 12 made of metal or plastic having a C-shaped cross section and having a spring property. It has been stopped.
[0022]
FIG. 2 shows a plan cross section of a portion where the sewage absorbing member 10 is locked to the operation portion 2 by the locking member 12.
The locking member 12 is attached in such a manner that the outer wall surface of the operation unit 2 is elastically tightened from the outside so that the sewage absorbing member 10 is sandwiched between the locking member 12 and the operation unit 2.
[0023]
As a result, the sewage absorbing member 10 is pressed and fixed from the outside to the outer wall surface of the operation unit 2 by the locking member 12. And if the latching member 12 is elastically deformed and removed from the outer wall surface of the operation part 2, the sewage absorbing member 10 can be removed and replaced with a new one.

The free end 10c positioned above the stop member 12 is placed thereon so as to cover the treatment instrument insertion port 3 portion.
[0028]
Therefore, even if the sewage in the body cavity that has passed through the treatment instrument insertion channel is ejected to the outside from the treatment instrument insertion port 3, most of it is absorbed by the sewage absorbing member 10 at the free end 10c, so that it is scattered around. Do not touch the surgeon's hand or face.
[0029]
And since the spilled liquid which exudes or exudes upward from the treatment instrument insertion port 3 is sucked up by the upper sewage absorbing member 10a, the operator's hand holding the operation unit 2 is not soiled.
[0030]
In addition, the sewage that tends to fall or fall from the treatment instrument insertion port 3 is sucked by the lower half of the lower sewage absorbing member 10b and does not fall below it. Therefore, the bed and the patient's skin are not soiled.
[0031]
When the treatment tool is inserted from the treatment tool insertion port 3, the free end 10c of the sewage absorbing member 10 is removed from the treatment tool insertion port 3 portion as shown by a two-dot chain line in FIG. What is necessary is just to insert in the treatment tool insertion port 3 as shown by the arrow A.
[0032]

[0034]
In addition, although the upper free end is utilized in FIG. 5 for the free end 10c of the sewage absorbing member 10 that covers the treatment instrument insertion port 3 portion, the lower free end may be used. Further, although only one locking member 12 is attached above the treatment instrument insertion port 3, a plurality of locking members 12 may be attached.
[0035]
FIG. 6 shows a fourth embodiment of the present invention, in which the sewage absorbing members 10a and 10b arranged separately on the upper side and the lower side of the treatment instrument insertion port 3 are combined into one locking member 12. It is made to lock with.
[0036]
The material and cross-sectional shape of the locking member 12 are the same as those in the first embodiment shown in FIG. 2, but the upper and lower sewage absorbing members 10a and 10b can be pressed simultaneously. It is formed long in the vertical direction, and a hole 12a for allowing the protrusion 4 to pass therethrough is formed in the central portion. Reference numeral 13 denotes a protruding finger hook.
