【発明の属する技術分野】
本発明は、超音波内視鏡の処置具挿通チャンネルを介して体腔内に導入される超音波内視鏡用処置具に関する。
【0002】
【従来の技術】
従来より、体腔内の患部を検査診断するため、内視鏡や、超音波内視鏡が使用されている。この超音波内視鏡では、例えば体腔壁表面をとらえた内視鏡画像に加えて、この体腔壁より内部の断層像である超音波画像が得られる。そして、体腔内を内視鏡画像で観察しながら、穿刺針を用いて胃や十二指腸の消化管壁等から、超音波画像で観察した膵臓、肝臓、腎臓等の深部臓器の目的部位に穿刺針を穿刺することによって、体腔内組織の採取や体液の採取を行える。
【0003】
前記超音波内視鏡を用いて超音波診断を行う場合、内視鏡画像を内視鏡観察用の表示装置の画面上に表示させる一方で、超音波画像を起音波観察用の表示装置の画面上に表示させる。このように表示装置の画面上に内視鏡画像或いは超音波画像を表示させて観察を行う際、内視鏡画像に比べて暗く表示される超音波画像をより見易くするために手術室内を薄暗くしている。
【0004】
【発明が解決しようとする課題】
しかしながら、手術室内が薄暗いことによって、術中に内視鏡処置具の受渡しに手間取ったり、受け取った穿刺針を処置具挿通チャンネルに導入する際に穿刺針の先端位置の把握を容易に行えない等の不都合が生じる。このため、術者によっては、手術室内を明るくして取り扱い性を優先させるため、観察画像の見易さが犠牲になるという不具合が生じる。
【0005】
本発明は上記事情に鑑みてなされたものであり、観察画像の見易い薄暗い手術室内での取扱いに優れた超音波内視鏡用処置具を提供することを目的にしている。
【0006】
【課題を解決するための手段】
本発明の超音波内視鏡用処置具は、超音波内視鏡に設けられている処置具挿通チャンネルに挿通されて体腔内に導入される超音波内視鏡用処置具であって、
前記超音波内視鏡用処置具の所定部位に発光手段を設けている。そして、この発光手段は、蓄光性夜光顔料である。
【0007】
これらの構成によれば、手術を開始する際に手術室内を薄暗くすると、超音波内視鏡用処置具の所定部位に設けられた蓄光性夜光顔料が発光して、薄暗い手術室でも容易に超音波内視鏡用処置具の所定部位の視認を行える。
【0008】
【発明の実施の形態】
以下、図面を参照して本発明の実施の形態を説明する。
図1及び図2は本発明の一実施形態に係り、図1は超音波内視鏡及び超音波内視鏡用処置具を説明する図、図2は穿刺針を説明する図である。
【0009】
図1に示すように超音波内視鏡用処置具(以下、超音波処置具と略記する)1は、超音波内視鏡2の図示しない処置具挿通チャンネルを介して体腔内に導かれる。
【0010】
前記超音波内視鏡2は、体腔内に挿入される細長の挿入部3と、この挿入部3の基端部に設けられた操作部4と、この操作部4の基端面に配置した接眼部5と、前記操作部4から延出するユニバーサルコード6と、このユニバーサルコード6の基端部に設けられたコネクタ7とで主に構成されている。
【0011】
前記操作部4の挿入部3側には例えば前記超音波処置具1などを挿入する処置具挿通チャンネルの導入口になる処置具挿入口8が設けられている。この処置具挿入口8は、挿入部先端部3aに形成されている処置具導出口9に挿入部3内に挿通配置された図示しない処置具挿通用チャンネルチューブを介して連通している。したがって、前記処置具挿入口8から超音波処置具1を挿入していくことによって、処置具導出口9から超音波処置具1の先端が導出されるようになっている。
【0012】
図2に示すように本実施形態の超音波処置具は例えば穿刺針10である。この穿刺針10は、処置具挿通チャンネルに挿入されるシース11と、このシース11の端部に配置された把持部を兼ねる操作部12と、この操作部12を介して前記シース11内に進退自在に挿通配置される先端部が鋭利な形状に形成された細長で薄肉の例えばステンレスパイプで形成された針管13とで主に構成されており、この針管13内には先端を鋭利な形状に形成したスタイレット14が挿脱自在に配置されるようになっている。
【0013】
前記操作部12は、前記シース11の基端部が固設される樹脂部材で形成した操作部本体15と、この操作部本体15に対して摺動自在に設けられる樹脂部材で形成したスライダ16と、このスライダ16の前記操作部本体15に対する摺動距離を測定結果に応じて所望の値に設定可能にするストッパ17とで主に構成されている。
【0014】
前記ストッパ17は、前記操作部本体15に対して摺動自在に配置される例えば樹脂製のストッパ部材17aと、このストッパ部材17aに螺合配置されて、ストッパ部材17aを所望の位置に固定する例えば金属製の固定ネジ17bとを備えて構成されている。
【0015】
前記操作部本体15の先端部には前記シース11の基端部が固設された樹脂製の接続部18が接着固定されている。この接続部18の先端側内孔側には前記処置具挿入口8に前記超音波処置具1を連結固定するための図示しない2条ネジが形成されている。
【0016】
なお、前記スライダ16の基端部には細径部16aが形成されており、この細径部16aの基端部開口には樹脂製の吸引口金部材19が配置されている。そして、この吸引口金部材19には樹脂製のスタイレットつまみ14aが着脱自在に配置されるようになっている。
【0017】
本実施形態の穿刺針10では、前記針管13の先端部所定位置表面に超音波を反射させるための複数の円環状の溝である円環溝20、…、20を複数設けるとともに、薄暗い手術室内で発光する発光手段である蓄光性夜光顔料を使用した夜光塗料が所定範囲に塗布してある。また、前記シース11、ストッパ部材17a及びスタイレットつまみ14aを、前記蓄光性夜光顔料を混入した樹脂部材で形成している。さらに、前記スタイレット14の先端部所定範囲にも前記夜光塗料を塗布している。
【0018】
なお、本実施形態においては超音波内視鏡2の操作部4に設けられている処置具挿入口8に前記夜光塗料を塗布している。
【0019】
上述のように構成した超音波内視鏡用処置具1の作用を説明する。
まず、超音波内視鏡を使用して検査等を行う際、超音波内視鏡2とともに滅菌袋に収納された超音波処置具1を準備する。この準備段階のとき、滅菌袋内の超音波処置具1が手術室内の照明光にさらされることによって、塗料又は樹脂部材の蓄光性夜光顔料に光が蓄えられていく。
【0020】
このため、超音波内視鏡下で検査等を開始する際に手術室内を薄暗くすると、超音波内視鏡2の処置具挿入口8が発光するとともに、滅菌袋に収納されている超音波処置具1の所定部位である図2に示すシース11、針管13、スタイレット14、スタイレットつまみ14a、ストッパ部材17aが発光状態になる。
【0021】
次に、超音波内視鏡2を操作している術者から超音波処置具1を使用する旨が伝達されると、助手或いは看護士は発光している超音波処置具1が収納されている滅菌袋を開封して超音波処置具1を取り出して、発光状態のシース11の先端側を術者に手渡す。
【0022】
次いで、術者は、受け渡されたシース11の先端側を把持して、発光状態の処置具挿入口8を介して前記シース11を処置具挿通チャンネル内に挿入していく。このことによって、このシース11が処置具導出口9まで導かれていく。
【0023】
そして、前記処置具導出口9から超音波処置具1が突出すると、図示しない起音波観察用表示装置の画面上に表示されている超音波観察画像上に前記シース11の所定位置に配置されている針管13の先端部に設けた円環溝20、…、20が明瞭に描出される。
【0024】
ここで、シース11の先端と目的部位との位置関係を設定し、その後、シース11の先端と目的部位との距離の測定を行い、前記固定ネジ17bを緩め、前記距離に対応するように発光状態のストッパ部材17aを目盛り15aを確認しながら操作部本体15上を摺動移動させ、所定位置まで移動したところで固定ネジ17bを締結する。
【0025】
この後、術者は、スライダ16を把持し、このスライダ16を前記ストッパ17に向けて素早く移動させる。このことによって、スタイレット14及び針管13の先端が目的部位に確実に穿刺される。このとき、超音波内視鏡2の図示しない照明光学系から観察部位に向けて出射されている照明光によって針管13の先端部が照明されることによって、この針管13の先端部に塗布されている夜光塗料に光が蓄えられていく。
【0026】
前記針管13が目的部位まで到達したことを前記超音波観察画像上で確認したなら、術者は発光状態のスタイレットつまみ14aとともにスタイレット14を吸引口金部材19から引き抜く。そして、看護士等に発光状態のスタイレットつまみ14a及びスタイレット先端部を見えるようにして手渡す。その後、この吸引口金部材19の連結部に図示しない注射筒等を接続して体腔内組織の吸引を行って、深部組織部位の生検を達成する。
【0027】
その後、術者が、この超音波処置具1を処置具挿通チャンネルから抜去したなら、術者は超音波処置具1の操作部12に設けられているストッパ部材17aと針管13の先端部を看護士等に見えるようにして超音波処置具1の手渡しを行い、超音波内視鏡下の検査を続行する。なお、超音波内視鏡下の検査が終了したなら前記超音波処置具1は廃棄される。
【0028】
このように、超音波内視鏡用処置具を構成する、シース、ストッパ部材及びスタイレットつまみを、蓄光性夜光顔料を混入した樹脂部材で形成するとともに針管及びスタイレットの先端部に蓄光性夜光顔料を使用した夜光塗料を塗布することによって、手術室内の照明光や超音波内視鏡の照明光学系からの照明光が蓄光性夜光顔料に蓄えらて、手術室内を超音波画像を見易くするために薄暗くしたとき、蓄光性夜光顔料が発光状態になって超音波内視鏡用処置具の受渡しをスムーズ且つ容易に行うことができる。
【0029】
また、超音波内視鏡の操作部に設けられている処置具挿入口にも蓄光性夜光顔料を使用した夜光塗料を塗布することによって、超音波内視鏡用処置具を容易に処置具挿入口に導入することができる。
【0030】
これらのことによって、薄暗い手術室内での超音波内視鏡用処置具の取扱い性が大幅に向上する。
【0031】
さらに、スタイレットや針管の鋭利な先端の視認を行うことができることによって、これら先端が手や指に刺さって発生する医療災害が未然に防止される。
【0032】
なお、薄暗い手術室内で、吸引口金部材や目盛りの視認を行えるように、吸引口金部材を蓄光性夜光顔料を混入した樹脂部材で形成したり、目盛り或いはその周囲に蓄光性夜光顔料を使用するようにしてもよい。また、前記操作部の凹部に穿刺針の仕様を表す記号を蓄光性夜光顔料を使用して記入するようにしてもよい。さらに、シース、ストッパ部材、スタイレットつまみ及び吸引口金部材を、蓄光性夜光顔料を混入した樹脂部材で形成する代わりに、シース、ストッパ部材及びスタイレットの所定部位に蓄光性夜光顔料を使用した夜光塗料を塗布するようにしてもよい。このとき、少なくともシースの先端部に夜光塗料を塗布する。
【0033】
尚、本発明は、以上述べた実施形態のみに限定されるものではなく、発明の要旨を逸脱しない範囲で種々変形実施可能である。

It is possible to visually recognize a predetermined portion of the treatment tool for an ultrasonic endoscope.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 and 2 relate to an embodiment of the present invention. FIG. 1 is a diagram illustrating an ultrasonic endoscope and a treatment tool for the ultrasonic endoscope, and FIG. 2 is a diagram illustrating a puncture needle.
[0009]
As shown in FIG. 1, a treatment tool for an ultrasonic endoscope (hereinafter abbreviated as an ultrasonic treatment tool) 1 is guided into a body cavity through a treatment tool insertion channel (not shown) of the ultrasonic endoscope 2.
[0010]
The ultrasonic endoscope 2 includes an elongated insertion section 3 inserted into a body cavity, an operation section 4 provided at a base end of the insertion section 3, and a contact section arranged on a base end surface of the operation section 4. It is mainly composed of an eye 5, a universal cord 6 extending from the operation section 4, and a connector 7 provided at a base end of the universal cord 6.
[0011]
On the insertion section 3 side of the operation section 4, a treatment tool insertion port 8 serving as an introduction port of a treatment tool insertion channel into which the ultrasonic treatment tool 1 and the like are inserted is provided. The treatment instrument insertion port 8 is in communication with a treatment instrument outlet 9 formed in the distal end portion 3a of the insertion section via a treatment instrument insertion channel tube (not shown) inserted through the insertion section 3. Therefore, by inserting the ultrasonic treatment tool 1 from the treatment tool insertion port 8, the distal end of the ultrasonic treatment tool 1 is drawn out from the treatment tool outlet 9.
[0012]
As shown in FIG. 2, the ultrasonic treatment device of the present embodiment is, for example, a puncture needle 10. The puncture needle 10 includes a sheath 11 inserted into the treatment instrument insertion channel, an operation unit 12 serving also as a grip unit disposed at an end of the sheath 11, and advances and retreats into the sheath 11 via the operation unit 12. The distal end portion which is freely inserted and disposed is mainly constituted by an elongated and thin-walled needle tube 13 formed of, for example, a stainless steel pipe formed in a sharp shape. The formed stylet 14 is arranged so that it can be inserted and removed.
[0013]
The operating section 12 includes an operating section main body 15 formed of a resin member to which the base end of the sheath 11 is fixed, and a slider 16 formed of a resin member provided slidably with respect to the operating section main body 15. And a stopper 17 for setting a sliding distance of the slider 16 with respect to the operation section main body 15 to a desired value according to a measurement result.
[0014]
The stopper 17 is, for example, a resin stopper member 17a slidably disposed with respect to the operation section main body 15, and is screwed to the stopper member 17a to fix the stopper member 17a at a desired position. For example, a metal fixing screw 17b is provided.
[0015]
A resin connecting portion 18 to which a base end portion of the sheath 11 is fixed is fixed to a distal end portion of the operation portion main body 15 by adhesion. A double thread (not shown) for connecting and fixing the ultrasonic treatment instrument 1 to the treatment instrument insertion port 8 is formed on the distal end side inner hole side of the connection portion 18.
[0016]
A small-diameter portion 16a is formed at the base end of the slider 16, and a resin suction cap member 19 is disposed at the base end opening of the small-diameter portion 16a. A resin stylet knob 14a is detachably mounted on the suction base member 19.
[0017]
In the puncture needle 10 of the present embodiment, a plurality of annular grooves 20,..., 20 which are a plurality of annular grooves for reflecting ultrasonic waves are provided on the surface of a predetermined position of the distal end portion of the needle tube 13, and a dim operating room is provided. A luminous paint using a luminous luminous pigment, which is a luminous means that emits light, is applied in a predetermined range. The sheath 11, the stopper member 17a and the stylet knob 14a are formed of a resin member mixed with the luminous luminous pigment. Further, the luminous paint is also applied to a predetermined range of the tip of the stylet 14.
[0018]
In the present embodiment, the luminous paint is applied to the treatment tool insertion port 8 provided in the operation unit 4 of the ultrasonic endoscope 2.
[0019]
The operation of the ultrasonic endoscope treatment tool 1 configured as described above will be described.
First, when performing an inspection or the like using an ultrasonic endoscope, the ultrasonic treatment instrument 1 housed in a sterilization bag together with the ultrasonic endoscope 2 is prepared. In this preparatory stage, the ultrasonic treatment instrument 1 in the sterilization bag is exposed to the illumination light in the operating room, whereby light is accumulated in the luminous pigment of the paint or the resin member.
[0020]
For this reason, if the operating room is dim when starting an examination or the like under the ultrasonic endoscope, the treatment instrument insertion port 8 of the ultrasonic endoscope 2 emits light and the ultrasonic treatment stored in the sterilization bag. The sheath 11, the needle tube 13, the stylet 14, the stylet knob 14a, and the stopper member 17a shown in FIG.
[0021]
Next, when the operator operating the ultrasonic endoscope 2 is notified that the ultrasonic treatment tool 1 is to be used, the assistant or the nurse stores the light-emitting ultrasonic treatment tool 1. The sterilizing bag is opened, the ultrasonic treatment tool 1 is taken out, and the distal end side of the sheath 11 in the light emitting state is handed to the operator.
[0022]
Next, the surgeon grasps the distal end side of the delivered sheath 11 and inserts the sheath 11 into the treatment instrument insertion channel through the treatment instrument insertion port 8 in a light emitting state. As a result, the sheath 11 is guided to the treatment instrument outlet 9.
[0023]
When the ultrasonic treatment tool 1 protrudes from the treatment tool outlet 9, the ultrasonic treatment tool 1 is arranged at a predetermined position of the sheath 11 on an ultrasonic observation image displayed on a screen of a not-shown display for sound emission observation. The annular grooves 20,..., 20 provided at the distal end of the needle tube 13 are clearly depicted.
[0024]
Here, the positional relationship between the distal end of the sheath 11 and the target site is set, then the distance between the distal end of the sheath 11 and the target site is measured, the fixing screw 17b is loosened, and light emission is performed in accordance with the distance. The stopper member 17a in the state is slid and moved on the operation section main body 15 while checking the scale 15a, and when the stopper member 17a moves to a predetermined position, the fixing screw 17b is fastened.
[0025]
Thereafter, the surgeon grasps the slider 16 and quickly moves the slider 16 toward the stopper 17. This ensures that the tip of the stylet 14 and the needle tube 13 are punctured into the target site. At this time, the distal end of the needle tube 13 is illuminated by the illumination light emitted from the illumination optical system (not shown) of the ultrasonic endoscope 2 toward the observation site, and is applied to the distal end of the needle tube 13. The light is stored in the luminous paint.
[0026]
When the operator confirms that the needle tube 13 has reached the target site on the ultrasonic observation image, the operator pulls out the stylet 14 from the suction base member 19 together with the stylet knob 14 a in a light emitting state. Then, the light emitting stylet knob 14a and the stylet tip are handed over to a nurse or the like. Thereafter, a syringe (not shown) or the like is connected to the connection portion of the suction base member 19 to suction tissue in the body cavity, thereby achieving a biopsy of a deep tissue site.
[0027]
Thereafter, if the surgeon removes the ultrasonic treatment instrument 1 from the treatment instrument insertion channel, the surgeon cares for the stopper member 17 a provided on the operation section 12 of the ultrasonic treatment instrument 1 and the distal end of the needle tube 13. The ultrasonic treatment tool 1 is handed over so as to be seen by a technician or the like, and the inspection under the ultrasonic endoscope is continued. When the examination under the ultrasonic endoscope is completed, the ultrasonic treatment instrument 1 is discarded.
[0028]
As described above, the sheath, the stopper member, and the stylet knob constituting the treatment device for an ultrasonic endoscope are formed of a resin member mixed with a luminous luminous pigment, and the luminous luminous is provided at the tip of the needle tube and the stylet. By applying a luminous paint using a pigment, the illuminating light in the operating room and the illuminating light from the illuminating optical system of the ultrasonic endoscope are stored in the luminous luminous pigment to make it easy to see the ultrasonic image in the operating room. Therefore, when the light is made dim, the luminous luminous pigment becomes luminous, and the delivery of the ultrasonic endoscope treatment tool can be performed smoothly and easily.
[0029]
In addition, by applying a luminous paint using a luminous luminous pigment to the treatment tool insertion port provided in the operation unit of the ultrasonic endoscope, the treatment tool for the ultrasonic endoscope can be easily inserted. Can be introduced into the mouth.
[0030]
As a result, the handling of the ultrasonic endoscope treatment tool in a dim operating room is greatly improved.
[0031]
Further, since the sharp tips of the stylet and the needle tube can be visually recognized, a medical disaster caused by the tips being stabbed by a hand or a finger is prevented.
[0032]
