Description

【０００１】
【発明の属する技術分野】
この発明は、内視鏡の処置具挿通チャンネルの入口部分に配置される内視鏡の鉗子栓に関する。
【０００２】
【従来の技術】
内視鏡の鉗子栓は、処置具挿通チャンネルを介して体内汚液等が噴出しないように処置具挿通チャンネルの入口部分の栓をし、しかも処置具挿通チャンネルに処置具を挿脱する際には栓を開閉する特別な操作を必要としないものでなければならない。
【０００３】
また、鉗子栓は消耗品なので容易に交換できることが望ましい。そこで、内視鏡の処置具挿通チャンネルの入口の表面部分に着脱自在な弾力性のあるゴム材料からなる蓋体に閉鎖膜を形成し、通常は自己の弾力性によって閉じた状態を維持し、処置具挿通チャンネルに挿脱される処置具によって押し広げられるスリットを閉鎖膜に形成した構成をとるものがある。
【０００４】
【発明が解決しようとする課題】
しかし、そのような鉗子栓は、閉鎖膜にスリットが形成された弾力性のある蓋体が処置具挿通チャンネルの入口の表面部分に取り付けられただけの構成なので、挿入される処置具の方向性が規制されない。
【０００５】
そのため、処置具が斜め向きに差し込まれて閉鎖膜に無理な力が加わり、閉鎖膜やスリットが変形、損傷して、鉗子栓の密閉性が低下してしまう場合がある。また、鉗子栓の入口から外側に処置具の手元側シャフトが垂れ下がる状態になっているときにも、同様の不具合が発生する場合がある。
【０００６】
そこで本発明は、処置具によって押し広げられる通路が形成された弾力性のある蓋体が内視鏡の処置具挿通チャンネルの入口の表面部分に着脱自在に取り付けられた鉗子栓において、処置具が真っ直ぐに差し込まれるようにして、処置具使用による消耗の程度が緩和された内視鏡の鉗子栓を提供することを目的とする。
【０００７】
【課題を解決するための手段】
上記の目的を達成するため、本発明の内視鏡の鉗子栓は、弾力性のある部材により形成されて内視鏡の処置具挿通チャンネルの入口の表面部分に着脱自在に取り付けられた蓋体に閉鎖膜が形成され、処置具挿通チャンネルに挿脱される処置具によって押し広げられる通路が閉鎖膜に形成された内視鏡の鉗子栓において、通路に対して真っ直ぐに連通する剛性材料からなる案内筒を、蓋体に対して傾かないように蓋体の外面側に突設したものである。
【０００８】
なお、蓋体がゴム材によって形成されていて、案内筒が蓋体と一体に形成されていてもよく、その場合に、案内筒の基端部側に鍔が突設されていて、その鍔部分が蓋体内にインサートされていてもよい。
【０００９】
また、蓋体が、処置具挿通チャンネルの入口部分に配置された弾力性のある受け部材に対して弾力的に着脱自在であってもよく、通路が、通常は自己の弾力性によって閉じた状態を維持し、処置具挿通チャンネルに挿脱される処置具によって押し広げられるスリットであってもよい。
【００１０】
また、通路が小孔であり、通常は自己の弾力性によって閉じた状態を維持し処置具挿通チャンネルに挿脱される処置具によって押し広げられるスリットが受け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例を説明する。
図７は内視鏡を示しており、可撓管によって外装された挿入部１の基端が操作部２の下端に連結されている。
【００１２】
挿入部１内に挿通配置された処置具挿通チャンネル３の先端は挿入部１の先端において外部に開口し、処置具挿通チャンネル３の入口部分に取り付けられた鉗子栓１０が、操作部２の下端付近に配置されている。
【００１３】
図１と図２は鉗子栓１０の正面断面図と側面断面図であり、鉗子栓１０は、操作部２から突出して処置具挿通チャンネル３の入口端部に設けられた入口口金３０に対して着脱自在に取り付けられている。
【００１４】
鉗子栓１０は、各々が弾力性のあるゴム材によって形成された樽状部材１１（受け部材）と蓋状部材１２とを、直列に配置して構成されており、樽状部材１１と蓋状部材１２は、入口口金３０の外周面に形成された第１と第２の円周溝３２，３３に着脱自在に嵌め込まれて取り付けられている。
【００１５】
樽状部材１１は、その内周面に突設された弾性突起１３が入口口金３０の口元近傍に形成された第１の円周溝３２に嵌め込まれており、弾性突起１３の周辺を弾性変形させることにより、第１の円周溝３２に係脱させることができる。
【００１６】
樽状部材１１には、中心にスリット１５が形成された閉鎖膜１４が、入口口金３０の開口端に対向する位置に形成されている。スリット１５は、通常は自己の弾力性によって閉じた状態を維持しており、処置具が通されるとそれによって押し広げられる。また、スリット１５より手前側には、注射筒の先端を受けるためのパッキン部１６が環状に内方に突出して形成されている。
【００１７】
蓋状部材１２は、入口口金３０の基部に形成された第２の円周溝３３に弾力的に着脱自在に取り付けられた環状部２１に、柔軟な連結バンド部２２を介して蓋部２３（蓋体）が連結されて構成されている。
【００１８】
蓋部２３は、樽状部材１１の開口部に外方から着脱自在に嵌め込まれ、蓋部２３の嵌め込まれる部分の先端に突設された鍔部２４が、樽状部材１１の開口部の内周に形成された円周溝１７に係脱自在である。
【００１９】
そして、蓋部２３側を弾力的に変形させて鍔部２４を円周溝１７に係合させることにより、蓋部２３が樽状部材１１の開口部に係止された状態になり、鍔部２４を弾性変形させて円周溝１７から外すことにより蓋部２３が樽状部材１１の開口部から外れる。
【００２０】
蓋部２３の底部分は閉鎖膜２６になっていて、その中央であって処置具挿通チャンネル３の入口に真っ直ぐに通じる位置に小孔２７が形成されている。小孔２７は、処置具が通されるとそれによって弾力的に押し広げられる。
【００２１】
このように形成された蓋部２３の外表面側には、差し込まれる処置具を案内するための案内筒２９が、金属又は硬質プラスチック等の剛性材料によって円筒状に形成されて突設されている。案内筒２９の内径寸法は、使用対象とする処置具の最大径より僅かに太い程度の寸法に設定されている。
【００２２】
案内筒２９には、蓋部２３の外表面に密着する大鍔部２９ａが軸線と垂直方向に突設され、さらに、軸線と垂直方向に基端部に突設された小鍔部２９ｂが蓋部２３内にインサートされて蓋部２３と一体的に形成されている。
【００２３】
このようにして、案内筒２９は蓋部２３の外表面から垂直に突出していて、それ以外の方向には傾かず、小孔２７、スリット１５及び入口口金３０の中心が、案内筒２９の軸線のほぼ延長線上に位置している。
【００２４】
図３は、上述のように構成された鉗子栓１０から処置具挿通チャンネル３に処置具１００が挿通されている状態を示しており、小孔２７とスリット１５が処置具１００のシャフトによって弾力的に押し広げられ、処置具挿通チャンネル３内からの圧力漏れが発生しない状態で処置具１００が処置具挿通チャンネル３に通される。
【００２５】
そして、案内筒２９が蓋部２３の外表面から垂直に真っ直ぐに突設されているので、案内筒２９を通過した処置具１００は、案内筒２９の軸線の延長線方向にある小孔２７、スリット１５へと案内されてそれらを通過する。
【００２６】
したがって、閉鎖膜２６，１４及び小孔２７、スリット１５等を変形、損傷させることなく処置具１００を差し込むことができる。また、鉗子栓１０の入口から外側に処置具１００のシャフトが垂れ下がった状態でも、その曲げ荷重が案内筒２９より奥側にはほとんど伝わらないので、閉鎖膜２６，１４や小孔２７、スリット１５の変形、損傷が発生しない。
【００２７】
なお、図４に示されるように、樽状部材１１から蓋部２３を取り外して、樽状部材１１に注射筒２００を差し込むことにより、スリット１５が弾力的に押し広げられると共に注射筒２００の先端がパッキン部１６に嵌め込まれ、注射筒２００から処置具挿通チャンネル３内へ薬液等を漏れなく注入することができる。
【００２８】
図５は、本発明の第２の実施例の鉗子栓１０を示しており、蓋部２３に設けられた閉鎖膜２６にスリット１５（通路）が形成され、樽状部材１１に設けられた閉鎖膜１４に小孔２７が形成された鉗子栓１０に本発明を適用したものであり、案内筒２９が蓋部２３の外表面から垂直に突出して設けられている。
【００２９】
この実施例の構成のうち、スリット１５、小孔２７以外の部分は前述の第１の実施例と同じであり、第１の実施例と同様の作用効果が得られる。図６は、その樽状部材１１に注射筒２００が取り付けられた状態を示している。
【００３０】
【発明の効果】
本発明によれば、弾力性のある部材により形成された蓋体に閉鎖膜が形成され、その閉鎖膜に、処置具挿通チャンネルに挿脱される処置具によって押し広げられる通路が形成された内視鏡の鉗子栓において、通路に対して真っ直ぐに連通する剛性材料からなる案内筒を、蓋体に対して傾かないように蓋体の外面側に突設したことにより、処置具が通路に向かって真っ直ぐに差し込まれるので、処置具使用により閉鎖膜等が変形、損傷せず、鉗子栓の消耗が大幅に緩和される。

BACKGROUND OF THE INVENTION
The present invention relates to an endoscopic forceps plug disposed at an entrance portion of a treatment instrument insertion channel of an endoscope.
[0002]
[Prior art]
The forceps plug of the endoscope plugs the entrance portion of the treatment instrument insertion channel so that in-vivo sewage or the like does not spout through the treatment instrument insertion channel, and when the treatment instrument is inserted into and removed from the treatment instrument insertion channel. Must not require any special operation to open or close the plug.
[0003]
Moreover, since the forceps plug is a consumable item, it is desirable that it can be easily replaced. Therefore, a closure film is formed on a lid made of a resilient rubber material that is detachable on the surface portion of the entrance of the treatment instrument insertion channel of the endoscope, and is normally kept closed by its own elasticity. Some have a configuration in which a slit that is spread by a treatment tool inserted into and removed from a treatment tool insertion channel is formed in a closing membrane.
[0004]
[Problems to be solved by the invention]
However, such a forceps plug has a configuration in which a resilient lid having a slit formed in the closure membrane is attached to the surface portion of the entrance of the treatment instrument insertion channel. Is not regulated.
[0005]
For this reason, the treatment tool is inserted obliquely and an excessive force is applied to the closing membrane, so that the closing membrane and the slit are deformed and damaged, and the sealing performance of the forceps plug may be lowered. In addition, the same problem may occur when the proximal shaft of the treatment tool hangs outward from the entrance of the forceps plug.
[0006]
Therefore, the present invention provides a forceps plug in which a flexible lid formed with a passage to be expanded by a treatment instrument is detachably attached to a surface portion of an entrance of a treatment instrument insertion channel of an endoscope. An object of the present invention is to provide an endoscopic forceps plug in which the degree of wear due to use of a treatment tool is reduced by being inserted straight.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, the forceps plug of the endoscope of the present invention is a lid formed by a resilient member and detachably attached to the surface portion of the entrance of the treatment instrument insertion channel of the endoscope. In a forceps plug of an endoscope in which a passage to be expanded by a treatment instrument inserted into and removed from the treatment instrument insertion channel is formed in the closure membrane, the endoscope forceps plug is made of a rigid material that communicates straight with the passage. The guide tube protrudes from the outer surface side of the lid so as not to tilt with respect to the lid.
[0008]
The lid body may be formed of a rubber material, and the guide tube may be formed integrally with the lid body. In this case, a ridge projects from the proximal end side of the guide tube. The part may be inserted into the lid.
[0009]
Further, the lid may be elastically detachable with respect to the elastic receiving member arranged at the entrance portion of the treatment instrument insertion channel, and the passage is normally closed by its own elasticity. It may be a slit that is spread by a treatment instrument that is inserted into and removed from the treatment instrument insertion channel.
[0010]
Further, the passage may be a small hole, and a slit that is normally spread by a treatment instrument inserted and removed from the treatment instrument insertion channel while maintaining a closed state by its own elasticity may be formed in the receiving member.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described with reference to the drawings.
FIG. 7 shows an endoscope, and the proximal end of the insertion portion 1 covered with a flexible tube is connected to the lower end of the operation portion 2.
[0012]
The distal end of the treatment instrument insertion channel 3 inserted and disposed in the insertion section 1 opens to the outside at the distal end of the insertion section 1, and the forceps plug 10 attached to the inlet portion of the treatment instrument insertion channel 3 is connected to the lower end of the operation section 2. Located in the vicinity.
[0013]
1 and 2 are a front cross-sectional view and a side cross-sectional view of the forceps plug 10, and the forceps plug 10 protrudes from the operation section 2 and is against an inlet base 30 provided at the inlet end of the treatment instrument insertion channel 3. It is detachably attached.
[0014]
The forceps plug 10 is configured by arranging a barrel-shaped member 11 (receiving member) and a lid-shaped member 12, each formed of an elastic rubber material, in series, and the barrel-shaped member 11 and the lid-shaped member. The member 12 is detachably fitted in and attached to first and second circumferential grooves 32 and 33 formed on the outer peripheral surface of the inlet base 30.
[0015]
The barrel-shaped member 11 has an elastic protrusion 13 projecting on the inner peripheral surface thereof fitted in a first circumferential groove 32 formed in the vicinity of the mouth of the inlet base 30, and elastically deforms the periphery of the elastic protrusion 13. By doing so, the first circumferential groove 32 can be engaged and disengaged.
[0016]
In the barrel-shaped member 11, a closing film 14 having a slit 15 formed at the center is formed at a position facing the opening end of the inlet base 30. The slit 15 normally maintains a closed state by its own elasticity, and when the treatment instrument is passed, it is expanded. Further, on the front side of the slit 15, a packing portion 16 for receiving the tip of the syringe barrel is formed so as to project inwardly in an annular shape.
[0017]
The lid-like member 12 is attached to an annular portion 21 that is elastically detachably attached to a second circumferential groove 33 formed in the base portion of the inlet base 30 via a flexible connecting band portion 22. (Lid) is connected.
[0018]
The lid portion 23 is detachably fitted into the opening of the barrel-shaped member 11 from the outside, and the flange portion 24 protruding from the tip of the portion into which the lid portion 23 is fitted is located within the opening of the barrel-shaped member 11. It can be freely engaged with and disengaged from a circumferential groove 17 formed on the circumference.
[0019]
Then, the lid portion 23 side is elastically deformed to engage the collar portion 24 with the circumferential groove 17, whereby the lid portion 23 is locked to the opening of the barrel-shaped member 11, and the collar portion The lid portion 23 is removed from the opening of the barrel-shaped member 11 by elastically deforming 24 and removing it from the circumferential groove 17.
[0020]
A bottom portion of the lid portion 23 is a closing membrane 26, and a small hole 27 is formed at a position in the center of the lid portion 23 so as to communicate straight with the entrance of the treatment instrument insertion channel 3. The small hole 27 is elastically expanded when the treatment instrument is passed therethrough.
[0021]
On the outer surface side of the lid portion 23 formed in this way, a guide tube 29 for guiding a treatment instrument to be inserted is formed in a cylindrical shape and protruded from a rigid material such as metal or hard plastic. . The inner diameter dimension of the guide tube 29 is set to a dimension slightly thicker than the maximum diameter of the treatment instrument to be used.
[0022]
The guide tube 29 is provided with a large collar portion 29a that is in close contact with the outer surface of the lid portion 23, and protrudes in a direction perpendicular to the axis, and further has a small collar portion 29b that projects from the base end in the direction perpendicular to the axis. It is inserted into the portion 23 and formed integrally with the lid portion 23.
[0023]
In this way, the guide tube 29 protrudes perpendicularly from the outer surface of the lid 23 and does not incline in any other direction, and the center of the small hole 27, the slit 15 and the inlet base 30 is the axis of the guide tube 29. It is located almost on the extension line.
[0024]
FIG. 3 shows a state where the treatment instrument 100 is inserted from the forceps plug 10 configured as described above into the treatment instrument insertion channel 3, and the small hole 27 and the slit 15 are elastically formed by the shaft of the treatment instrument 100. The treatment instrument 100 is passed through the treatment instrument insertion channel 3 in a state where pressure leakage from the treatment instrument insertion channel 3 does not occur.
[0025]
Since the guide tube 29 is projected straight from the outer surface of the lid portion 23, the treatment instrument 100 that has passed through the guide tube 29 has a small hole 27 in the direction of the extension of the axis of the guide tube 29, They are guided to the slit 15 and pass through them.
[0026]
Therefore, the treatment instrument 100 can be inserted without deforming or damaging the closing films 26 and 14, the small holes 27, the slits 15 and the like. Even when the shaft of the treatment instrument 100 hangs down from the entrance of the forceps plug 10, the bending load is hardly transmitted to the back side from the guide tube 29, so that the closing films 26, 14, the small holes 27, the slits 15 are provided. No deformation or damage occurs.
[0027]
As shown in FIG. 4, the lid 23 is removed from the barrel-shaped member 11, and the syringe barrel 200 is inserted into the barrel-shaped member 11, so that the slit 15 is elastically expanded and the distal end of the syringe barrel 200. Is inserted into the packing portion 16, and the drug solution or the like can be injected from the syringe barrel 200 into the treatment instrument insertion channel 3 without leakage.
[0028]
FIG. 5 shows the forceps plug 10 according to the second embodiment of the present invention, in which a slit 15 (passage) is formed in the closing film 26 provided in the lid 23 and the closure provided in the barrel member 11. The present invention is applied to the forceps plug 10 in which a small hole 27 is formed in the membrane 14, and a guide tube 29 is provided so as to protrude vertically from the outer surface of the lid portion 23.
[0029]
Of the configuration of this embodiment, the portions other than the slit 15 and the small hole 27 are the same as those in the first embodiment described above, and the same effects as those in the first embodiment can be obtained. FIG. 6 shows a state where the syringe barrel 200 is attached to the barrel member 11.
[0030]
【The invention's effect】
According to the present invention, a closure membrane is formed on the lid formed by the elastic member, and a passage that is pushed and expanded by the treatment instrument inserted into and removed from the treatment instrument insertion channel is formed in the closure membrane. In the forceps plug of the endoscope, a guide tube made of a rigid material that communicates straight with the passage is provided on the outer surface side of the lid so as not to tilt with respect to the lid, so that the treatment instrument faces the passage. Therefore, the closure membrane is not deformed or damaged by using the treatment tool, and the consumption of the forceps plug is greatly reduced.
