- the sterilization pack 60 (see FIG. 11) is housed in a state of being fixed to the cutting tool 10. Furthermore, when the endoscope treatment system 1 is housed in the sterilization pack 60, the third lumen 16 holds the distal end shape of the insertion portion 11 in a predetermined curved shape at the distal end of the insertion portion 11.
- the pre-curve stylet 59 is inserted.
- the pre-curve stylet 59 is formed of a wire material harder than the multi-lumen tube 13.
- the shape of the pre-curve stylet 59 may be appropriately set according to the purpose of use of the endoscope treatment system 1.

More specifically, the longitudinal axis of the main body 52 of the second operation portion 45 is directed in the tangential direction of the tube body 3 wound circumferentially in the guide wire holder 2.
- the endoscope treatment system 1 is compactly wound when stored in the sterilization pack 60.
- the sterilization pack 60 is opened, and the endoscope treatment system 1 is taken out of the sterilization pack 60 with the high-frequency incision tool 10 or the guide wire holder 2 (step S1). Subsequently, the pre-curve stylet 59 is taken out from the distal end of the insertion portion 11 (step S2). Thereafter, the second operation unit 45 is held through the fingers through the rings 53 and 56 provided in the second operation unit 45 (step S3).
- the guide wire holder 2 is preferably located below the second operation unit 45. That is, the guide wire holder 2 is attached to the operation unit 30 so as to hang from the operation unit 30.
- the deformed portion 48 is bent by the weight of the guide wire holder 2 and the guide wire holder 2 is separated from the operation portion 30 as compared with the time when the endoscope treatment system 1 is stored (see FIG. 11 and FIG. 11). (See FIG. 14). Thereby, the space around the operation unit 30 is expanded.
- a high frequency power supply device (not shown) for supplying a high frequency current to the knife wire 19 is connected to the plug 55 provided in the operation unit 30.
- the operator inserts the distal end of the insertion portion 11 into the treatment instrument channel 101 of the endoscope apparatus 100 and causes the insertion portion 11 to protrude from the distal end of the treatment instrument channel 101. Then, the guide wire W is pushed out toward the distal end of the insertion portion 11. At this time, the operator exposes a portion of the total length of the guide wire W that is exposed between the wire insertion port 35 provided in the operation unit 30 and the opening 3a in which the guide wire W is drawn out in the tube body 3 (see FIG. 14). The guide wire W is advanced and retracted by holding the portion indicated by the symbol A.
- the position of the opening 3a through which the guide wire W is drawn out in the tube body 3 may be changed to the outside of the outermost periphery of the tube body 3 wound in a circumferential shape.
- the position of the opening 3 a can be changed by changing the mounting direction of the first recess 6 with respect to the tube body 3.
- the wire insertion port 35 located inside the circumference The opening 3a is located nearby, and the opening 3a is directed to the wire insertion opening 35.
- the distance between the wire insertion opening 35 and the opening 3a is short, and the curvature of the guide wire W exposed between the wire insertion opening 35 and the opening 3a can be reduced.
- the guide wire W is not easily buckled when the guide wire W is moved, and the guide wire W can be moved smoothly.
- the guide wire W is exposed more than when the opening 3a is located inside the circumference. Length increases. Thereby, the length which can move the guide wire W by one operation becomes longer than the case where the opening 3a is located inside the circumference.

- the main body 52 and the slider 54 of the second operation unit 45 in the operation unit 30 are positioned outside the outermost periphery of the tube body 3 wound in a circumferential shape. Therefore, the tube body 3 is difficult to touch the operator's hand when the endoscope treatment system 1 is used, and the tube body 3 is unlikely to get in the way. Furthermore, in this embodiment, when the second operation unit 45 is held by a suitable way of holding the second operation unit 45 in the endoscope treatment system 1, the guide wire holder 2 is suspended from the operation unit 30, and the guide The guide wire holder 2 is separated from the operation unit 30 by the weight of the wire holder 2.

Abstract
Description
本願は、2012年07月13日に、米国に仮出願された米国特許出願第61/671,247号に基づき優先権を主張し、その内容をここに援用する。
ガイドワイヤを挿入するシステムの例として、例えば、特許文献2には、処置対象部位へ挿入されるガイドワイヤを収納する収納部が処置具に取り付けられたシステムが開示されている。
また、処置具の使用時にガイドワイヤを処置具に挿通する手間を省く目的で、処置具にガイドワイヤが予め挿入された状態で一組のセットとして提供される処置システムも知られている。
また、ガイドワイヤをコンパクトに収納するための収納具が処置具に取り付けられたシステムも知られている。
たとえば、特許文献2に開示されたシステムでは、円周状に巻かれた管状体の内側にシリンジの押し子が配された構造を有しており、シリンジを操作する際に管状体が邪魔になって操作しづらい場合がある。
本発明の第3の態様によれば、上記第2の態様において、前記操作部には、前記ルーメンと連通するワイヤ挿入口が設けられており、前記ガイドワイヤホルダは、前記チューブ体に形成されて前記ガイドワイヤが延出する開口と、前記ワイヤ挿入口において前記ガイドワイヤが挿入される開口に前記チューブ体の開口が向かうように前記チューブ体を保持する保持具とを有してもよい。
上記各態様によれば、固定部材が、操作部の先端および基端がガイドワイヤホルダの円周の外側に位置するように操作部を前記ガイドワイヤホルダに連結するため、内視鏡処置具が操作者の手に触れにくく、内視鏡処置具が邪魔になりにくい。
本発明の一実施形態の内視鏡用処置システムについて説明する。図1は、本実施形態の内視鏡用処置システムを示す全体図である。
図1に示すように、内視鏡用処置システム1は、ガイドワイヤWがあらかじめ高周波切開具(内視鏡用処置具)10に取り付けられた状態で提供されるシステムである。ガイドワイヤWは、高周波切開具10を処置対象部位まで案内するために設けられた線材である。また、ガイドワイヤWは、柔軟であって且つトルク伝達性に優れた線材である。ガイドワイヤWは、柔軟なチューブ体3が円周状に巻かれて形成されたガイドワイヤホルダ2に収容され、チューブ体3に沿って巻かれた形状で提供される。そして、チューブ体3の一端に設けられた開口3aからガイドワイヤWが繰り出され、高周波切開具10に設けられた後述するワイヤ挿入口35を通じて高周波切開具10の内部に挿入される。
チューブ体3の材料は特に限定されない。たとえば、チューブ体3は、ポリ四フッ化エチレン(PTFE)、四フッ化エチレン六フッ化プロピレン樹脂(FEP)、ポリエチレン、ポリオレフィン、ポリアミド、塩化ビニール、ラテックス、天然ゴム、ポリサルフォン、ポリフェニルサルフォン、ポリエーテルイミド、POM、PEEK、ポリカーボネイト、ABS等の樹脂や、それらの合成樹脂材料によって形成される。
すなわち、第一凹部6に形成される凹部7の数は、2つ以上且つチューブ体3の巻き数未満であってもよい。
また、第二凹部8は、本実施形態における第二の取り付け態様として、円周状(本実施形態では渦巻状)に巻かれたチューブ体3のうち最も外側に位置するチューブ体3よりもさらに外側に上記開口3aを位置させる(図14参照)。
チューブ体3に対する第一凹部6の取り付け向きを変えてチューブ体3に保持具5を取り付けることによって、上述の第一の取り付け態様と第二の取り付け態様とを相互に切り替えることができる。
挿入部11は、先端11aと基端11bとを有する柔軟な長尺部材であり、生体組織を切開するための切開部12と、切開対象となる部位まで切開部12を案内するためのシース部(シース)25とを有する。
ナイフワイヤ19においてナイフチップ22の基端側の一部は、絶縁被覆21を有していない露出部23である。露出部23は、ナイフワイヤ19の全長のうちマルチルーメンチューブ13の外側に位置する範囲に設定されている。
絶縁被覆21は、ナイフワイヤ19において露出部23よりも基端側に設けられている。絶縁被覆21は、ナイフワイヤ19の素線20の外周面に絶縁を目的としたコーティングにより形成されている。
ナイフワイヤ19において露出部23よりも基端側は、挿入部11の基端側に向かって延びている。ナイフワイヤ19の基端は、操作部30(図5参照)に接続されている。
ガイドワイヤチューブ33は、先端側が第一分岐部31内で第三ルーメン16(図7参照)と連通されており、基端側がガイドワイヤ挿入部34に固定されている。
接続部36は、ワイヤ挿入口35の径方向にワイヤ挿入口35の外面から突出して形成されている。接続部36は、操作部30にガイドワイヤホルダ2を固定するための固定部材38(図9参照)を有する。図8に示すように、接続部36は、固定部材38を取り付けるための突起部37を有する。
固定部材38は、操作部30の先端30aおよび基端30bがガイドワイヤホルダ2の円周の外側に位置するように操作部30をガイドワイヤホルダ2に連結する。また、固定部材38に設けられた凹部40は、円周状に巻かれたチューブ体3において互いに隣接する部分に対して摩擦により係合する。また、凹部40は、チューブ体3の径方向断面においてチューブ体3の外面うち半周以上を覆う円弧状の凹形状を有している。凹部40は、円周状に巻かれたチューブ体3の少なくとも一箇所に係合可能であればよい。すなわち、固定部材38に設けられた凹部40は少なくとも1つあればよい。凹部40が2つ以上あると、チューブ体3をさらに強固に保持することができる。本実施形態では、凹部40は互いに隣接する4つの凹部40a~40dを有している。
また、固定部材38は、ワイヤ挿入口35においてガイドワイヤWが挿入される開口がガイドワイヤホルダ2の円周の内側に位置するように操作部30をガイドワイヤホルダ2に連結してもよい。
さらに、コネクタ46には、軸線方向に対して自由に変形する変形部48が設けられている。変形部48には、第二分岐部50が設けられている。
また、スライダ54には、指掛け用のリング56が設けられている。高周波切開具10の操作者は、本体52に設けられたリング53と、スライダ54に設けられたリング56とのそれぞれに指をいれて、スライド部51の操作をする。すなわち、本体52に対してスライダ54を進退移動させることにより、本体52の長手軸方向にナイフワイヤ19を移動させることができる。たとえば、本体52の基端側へ向かってスライダ54を移動させると、挿入部11の先端に配された切開部12において、ナイフワイヤ19によってマルチルーメンチューブ13の先端が基端側に引かれ、マルチルーメンチューブ13の先端が湾曲する。
操作部30に設けられたプラグ55には、高周波電流をナイフワイヤ19に供給するための高周波電源装置(不図示)が接続される。
必要に応じて、チューブ体3においてガイドワイヤWが繰り出される開口3aの位置を、円周状に巻かれたチューブ体3の最外周よりも外側に変えてもよい。開口3aの位置は、チューブ体3に対する第一凹部6の取り付け向きを変えることによって変更することができる。
逆に、円周状に巻かれたチューブ体3の最外周のさらに外側に開口3aが位置している場合、円周の内側に開口3aが位置している場合よりも、ガイドワイヤWの露出長さが長くなる。これにより、ガイドワイヤWを一動作にて移動させることができる長さが、円周の内側に開口3aが位置している場合よりも長くなる。
膵管H2が処置対象である場合には、ガイドワイヤWを膵管H2内に挿入する。
さらに、本実施形態では、内視鏡用処置システム1における第二操作部45の好適な持ち方により第二操作部45を持った場合、操作部30にガイドワイヤホルダ2がぶら下がる状態となり、ガイドワイヤホルダ2の自重によって、ガイドワイヤホルダ2が操作部30から離間する。この点でも、内視鏡用処置システム1の使用時にチューブ体3が操作者の手に触れにくく、チューブ体3が邪魔になりにくい。
また、円周状に巻かれたチューブ体3における最内周のさらに内側にワイヤ挿入口35が位置するので、円周状に巻かれたチューブ体3における外周のさらに外側にワイヤ挿入口35が位置する場合と比較して、滅菌パック60内に内視鏡用処置システム1をコンパクトに収納することができる。
また、第二凹部8によりガイドワイヤWが繰り出される開口3aの位置をチューブ体3よりも内側もしくは外側に切替可能であるため、操作部30とガイドワイヤホルダ2を固定せずに使用する場合に、開口3aを操作しやすい位置にして使用することが出来る。
たとえば、固定部材に形成された平面部は、固定部材に形成される凹部の底と面一となるように設けられていてもよい。この場合、凹部の底と面一な平面部によってチューブ体がより安定して保持され、ガイドワイヤホルダが振れ難くなる。
また、ガイドワイヤホルダのチューブ体は、固定部材および保持具よりも柔軟な部分と、固定部材および保持具よりも硬い部分とを有していてもよい。
この他、本発明は前述した説明によって限定されることはなく、添付のクレームの範囲によってのみ限定される。
