Description

Translated fromJapanese

本発明は、内視鏡観察下で病変部を切除する際に用いる、内視鏡用磁気アンカー遠隔誘導システム及び磁気アンカー遠隔誘導システムを用いた内視鏡による処置方法に関する。  The present invention relates to an endoscopic magnetic anchor remote guidance system and an endoscopic treatment method using the magnetic anchor remote guidance system used when excising a lesion under endoscopic observation.

従来、通常の手術において人体内部の病変部を切除する場合においては、把持鉗子を用いて病変部を持ち上げることにより病変部と隣接する正常組織との間隔を広げ、その状態で病変部と正常組織との間を切除している。しかし、例えば内視鏡的粘膜切除術(EMR)では、体内には内視鏡を一台しか挿入できないため、病変部を持ち上げることができず、注射針で病変部の周囲の正常粘膜に生理食塩水等を注入して病変部を浮き上がらせ、その状態で高周波ナイフやスネアなどを用いて病変部と正常粘膜の間の切除を行っていた。  Conventionally, when excising a lesion inside a human body in a normal operation, the distance between the lesion and the adjacent normal tissue is widened by lifting the lesion using a grasping forceps, and the lesion and the normal tissue are in that state. It is excised between. However, for example, in endoscopic mucosal resection (EMR), since only one endoscope can be inserted into the body, the lesion cannot be lifted, and the normal mucous membrane around the lesion cannot be lifted with an injection needle. Saline was injected to raise the lesion, and in that state, a high-frequency knife or snare was used to perform excision between the lesion and the normal mucosa.

しかし、このような従来の方法では、病変部を十分な位置まで持ち上げることができなかったため、病変部と正常組織との境界の切除部分を十分確保することができなかった。
また、病変部が扁平な形状である場合は、切除部分を作りだすことができないこともあった。
However, in such a conventional method, the lesioned part could not be lifted to a sufficient position, and thus a sufficient excision part at the boundary between the lesioned part and the normal tissue could not be secured.
In addition, when the lesioned part has a flat shape, it may not be possible to create an excised part.

さらに、切除作業中において、すでに切除した病変部が正常組織上に落ち込むことにより内視鏡による視界を妨げることがあり、特に病変部が大きい場合に顕著であった。そのため、切除部分を見ることができず、盲目的に切除するために正常部分を損傷して穿孔などの合併症が発生したり、血管を損傷して大出血をきたし、また出血時も出血部位の確認ができず止血できないことから重篤な合併症を来すことも考えられ、より安全な装置や処置方法が求められていた。  Further, during the excision work, the already excised lesioned part may fall on the normal tissue, thereby obstructing the field of view by the endoscope, particularly when the lesioned part is large. For this reason, the excised part cannot be seen, and in order to remove it blindly, the normal part is damaged and complications such as perforation occur, blood vessels are damaged, and major bleeding occurs. Since it could not be confirmed and hemostasis could not be achieved, serious complications could occur, and a safer device and treatment method were required.

そこで本出願人は、これらの問題点を解決すべく、人体の臓器内部の病変部を把持する把持部材と、把持部材に接続された磁性体からなる磁気アンカーと、把持部材と磁気アンカーとを連結するひも状の連結部材と、人体の外部に配置され、磁界を発生して磁気アンカーに動力を与える磁気アンカー誘導装置と、を備え、磁気アンカー誘導装置が発生する磁界によって磁気アンカーに動力を与えて、把持部材によって把持された病変部を持ち上げることを特徴とする磁気磁気アンカー遠隔誘導システムを提案し、特許出願している(特願2002−268239号)。  Therefore, in order to solve these problems, the applicant of the present invention has a gripping member for gripping a lesioned part inside a human organ, a magnetic anchor made of a magnetic body connected to the gripping member, and a gripping member and a magnetic anchor. A string-like connecting member to be connected, and a magnetic anchor guiding device that is arranged outside the human body and generates a magnetic field to power the magnetic anchor, and the magnetic anchor generates power by using the magnetic field generated by the magnetic anchor guiding device.

And the like, and a magneticanchor guiding device 40 that controls themagnetic anchor device 10 to be attracted outside the body (applies a magnetic force to the magnetic gripping member 11).

まず、図1から図3を参照して、磁気アンカー装置10の構成について説明する。
対称形状をなす磁性把持部材11は、強磁性材料板を折曲加工した弾性部材であり、自由状態においてその両側部の先端が接触するCリング状の基部12と、基部12の先端から前方に延びつつ拡開する一対の傾斜片13a、13aと、両傾斜片13a、13aの先端から延びる中間片13b、13bと、両中間片13b、13bの先端部を折曲して形成した爪部13c、13cとを具備している。さらに、基部12の後端部には挿入孔12aが穿設されている。強磁性材料の具体例としては、純鉄、鉄合金のほか、プラチナマグネット、希土類磁石、テルビウム・ディスプロシウム・鉄合金などの磁石がある。
First, the configuration of themagnetic anchor device 10 will be described with reference to FIGS. 1 to 3.
Themagnetic gripping member 11 having a symmetric shape is an elastic member obtained by bending a ferromagnetic material plate, and has a C-ring-shaped base portion 12 in which the tips of both side portions contact in a free state, and forward from the tip of thebase portion 12. A pair ofinclined pieces 13a, 13a that expand while extending,intermediate pieces 13b, 13b extending from the ends of bothinclined pieces 13a, 13a, andclaw portions 13c formed by bending the ends of bothintermediate pieces 13b, 13b , 13c. Further, aninsertion hole 12 a is formed in the rear end portion of thebase portion 12. Specific examples of the ferromagnetic material include magnets such as platinum magnet, rare earth magnet, terbium / dysprosium / iron alloy in addition to pure iron and iron alloy.

牽引分離部材(開閉手段)14は棒状の部材であり、その先端には、磁性把持部材11の挿入孔12aを貫通する一対の挿入片14aと、挿入片14aの先端に設けられた、基部12の内面に係合して、挿入片14aが基部12から抜け出すのを防止する抜け止め部14bとが設けられている。さらに、牽引分離部材14の基端部には鈎部14cが形成されている。牽引分離部材14は、プラスチックやSUS等の金属材料から成形されており、所定の切断力以上の強い力を受けると切断される程度の強度である。  The pulling / separating member (opening / closing means) 14 is a rod-shaped member, and at the tip thereof, a pair ofinsertion pieces 14a penetrating theinsertion hole 12a of themagnetic gripping member 11, and abase portion 12 provided at the tip of theinsertion piece 14a. And aretaining portion 14b that prevents theinsertion piece 14a from slipping out of thebase portion 12 by being engaged with the inner surface. Furthermore, aflange portion 14 c is formed at the proximal end portion of thetraction separation member 14. The pulling / separatingmember 14 is formed from a metal material such as plastic or SUS, and has such a strength that it can be cut when receiving a strong force exceeding a predetermined cutting force.

図1から図3等に示す両端が開口する筒状締付部材15は、可撓性のある材料からなるものである。この筒状締付部材15の内径は、磁性把持部材11の基部12が嵌合可能な寸法となっている。  Thecylindrical fastening member 15 having both ends opened as shown in FIGS. 1 to 3 and the like is made of a flexible material. Thecylindrical fastening member 15 has an inner diameter that allows thebase 12 of themagnetic gripping member 11 to be fitted.

図1に示す状態(磁性把持部材11が筒状締付部材15内に嵌合していない状態)から、筒状締付部材15に対して牽引分離部材14を相対的に後方に引くと、図2に示すように、磁性把持部材11の基部12が内向きに弾性変形しながら筒状締付部材15の内部に引き込まれる。すると、基部12が弾性変形しながらその径が小さくなり、両傾斜片13aと両中間片13bが互いに離れる開状態となる。
図3に示すように、筒状締付部材15に対して牽引分離部材14をさらに相対的に後方に引くと、磁性把持部材11が内向きに弾性変形しながら筒状締付部材15の内部にさらに引き込まれ、その傾斜片13aが筒状締付部材15の先端開口部に接触し、両傾斜片13aと両中間片13bと両爪部13cが互いに接近する閉状態となる。

Then, the diameter of thebase portion 12 is reduced while thebase portion 12 is elastically deformed, and the twoinclined pieces 13a and theintermediate pieces 13b are opened from each other.
As shown in FIG. 3, when thepulling separation member 14 is pulled further rearward relative to thecylindrical fastening member 15, the inside of thecylindrical fastening member 15 is elastically deformed inward while themagnetic gripping member 11 is elastically deformed inward. Then, theinclined piece 13a comes into contact with the tip opening of thecylindrical fastening member 15, and theinclined pieces 13a, theintermediate pieces 13b, and theclaw portions 13c are brought into a closed state.

Theinner rail 44 is slidably mounted with a magnetic guidingmember 46 that controls the magnetic grippingmember 11 to be attracted outside the body (which exerts a magnetic force on the magnetic gripping member 11), and the magnetic guidingmember 46 has left and right XY stages. 42 can move along therail 45. Themagnetic induction member 46 is obtained by fixing an electromagnet 47 having a structure in which a coil is wound around an iron core on abase 48, and the electromagnet 47 always faces the patient A side (see FIG. 5). Themagnetic induction member 46 may be a combination of a permanent magnet and an electromagnet, or a combination of two or more permanent magnets and electromagnets.

フレーム/レール43の外側のレール45には、フレーム/レール43全体の重量バランスを保つためのカウンターウエイト49がレール45に摺動自在に装着されている。カウンターウエイト49は、磁気誘導部材46の位置に応じて、その位置が変化する。例えば、磁気誘導部材46が患者Aの正面側に位置するときは、カウンターウエイト49は患者Aの背面側に位置し、磁気誘導部材46が患者Aの背面側にあるときは、カウンターウエイト49は患者Aの正面側に位置して、フレーム/レール43全体の重量バランスをとっている。
そして、以上説明した磁気誘導部材46、XYステージ42、フレーム/レール43により磁気アンカー誘導装置40が構成されている。
Acounterweight 49 for maintaining the weight balance of the entire frame /rail 43 is slidably mounted on therail 45 on therail 45 outside the frame /rail 43. The position of thecounterweight 49 changes depending on the position of themagnetic induction member 46. For example, when themagnetic guide member 46 is located on the front side of the patient A, thecounterweight 49 is located on the back side of the patient A, and when themagnetic guide member 46 is on the back side of the patient A, thecounterweight 49 is Located on the front side of the patient A, the entire frame /rail 43 is balanced in weight.
Themagnetic guide member 40, theXY stage 42, and the frame /rail 43 described above constitute the magneticanchor guide device 40.

次に、磁気アンカー遠隔誘導システムを用いた病変部Xの切除要領について説明する。
磁気アンカー遠隔誘導システムを用いた切除術の実施に先立っては、まず、図5及び図6に示すように、局所麻酔を施した患者Aをベッド41の床板41a上に横たわらせる。このとき、XYステージ42を操作して、フレーム/レール43のベッド41の長手方向位置を、患者Aの頭部A1とほぼ同じ位置にしておき、さらに、磁気誘導部材46及びカウンターウエイト49を所定の場所に位置させておく。
次に、XYステージ42を操作してフレーム/レール43を患者Aの正面側に配置させ、さらに、磁気誘導装置46をフレーム/レール43に沿って移動させて、磁気誘導部材46を切除術開始時位置に位置させる(図6参照)。
Next, the excision procedure of the lesion X using the magnetic anchor remote guidance system will be described.
Prior to performing excision using the magnetic anchor remote guidance system, first, as shown in FIGS. 5 and 6, the patient A subjected to local anesthesia is laid on thefloor plate 41 a of thebed 41. At this time, theXY stage 42 is operated so that the longitudinal direction position of thebed 41 of the frame /rail 43 is substantially the same position as the head A1 of the patient A, and themagnetic induction member 46 and thecounterweight 49 are set to a predetermined position. It is located in the place of.
Next, theXY stage 42 is operated to place the frame /rail 43 on the front side of the patient A, and themagnetic guiding device 46 is moved along the frame /rail 43 to start excision of the magnetic guidingmember 46. Position at the hour position (see FIG. 6).

次いで、図示を省略した可撓性を有するオーバーチューブを、患者Aの口から体内に挿入する。続いて、内視鏡20の挿入部21をオーバーチューブ内に挿入し、挿入部21の先端部をオーバーチューブの先端から突出させ、臓器(対象物)B(図8から図12参照)の病変部(対象部位)Xに近接させる(図示略)。このように、内視鏡20の挿入部21の先端を臓器B内に挿入すると、内視鏡20の挿入部21の先端面22に設けられた観察窓から得られた臓器B内の観察像が、図示を省略したテレビモニタに写し出される。  Next, a flexible overtube (not shown) is inserted from the mouth of patient A into the body. Subsequently, theinsertion portion 21 of theendoscope 20 is inserted into the overtube, the distal end portion of theinsertion portion 21 is protruded from the distal end of the overtube, and the lesion of the organ (target) B (see FIGS. 8 to 12) is detected. It is made to approach the part (target part) X (not shown). Thus, when the distal end of theinsertion portion 21 of theendoscope 20 is inserted into the organ B, the observation image in the organ B obtained from the observation window provided on thedistal end surface 22 of theinsertion portion 21 of theendoscope 20. Is displayed on a television monitor (not shown).

次いで、鉗子口24の入口24aから、先端部に注射針を具備するチューブ状の処置具(図示略)を鉗子チャンネルCに挿入して、その注射針を鉗子チャンネルCの出口23から突出させる。そして、注射針を病変部Xの周辺から臓器壁の粘膜下層B1に挿入して生理食塩水等を注入し、病変部Xを固有筋層B2から浮き上がらせておく(図8から図12参照)。  Next, a tube-like treatment tool (not shown) having an injection needle at the tip is inserted into the forceps channel C from the inlet 24 a of theforceps port 24, and the injection needle protrudes from theoutlet 23 of the forceps channel C. Then, an injection needle is inserted from the periphery of the lesion X into the submucosa B1 of the organ wall and physiological saline or the like is injected, and the lesion X is lifted from the proper muscle layer B2 (see FIGS. 8 to 12). .

続いて、鉗子チャンネルCから該処置具を取り出す。次に、挿入管31、挿入コイル32、規制管33、フック部34、操作ワイヤ35、及び操作部を一体化した操作装置30を、鉗子口24から鉗子チャンネルCに挿入する。
この際、鉗子チャンネルCに操作装置30を挿入すると、操作装置30の操作部及び、挿入管31と挿入コイル32と操作ワイヤ35の基端部が鉗子口24の後方に突出する(図示略)。
また、筒状締付部材15は可撓性を有する材料から成形されており、かつ、挿入コイル32は屈曲自在なので、挿入部21が屈曲していても、これらの部材は鉗子チャンネルC内をスムーズに移動することができる。
Subsequently, the treatment tool is taken out from the forceps channel C. Next, theoperation device 30 in which theinsertion tube 31, theinsertion coil 32, therestriction tube 33, thehook portion 34, theoperation wire 35, and the operation portion are integrated is inserted into the forceps channel C from theforceps port 24.
At this time, when theoperation device 30 is inserted into the forceps channel C, the operation portion of theoperation device 30 and the proximal end portions of theinsertion tube 31, theinsertion coil 32, and theoperation wire 35 protrude to the rear of the forceps port 24 (not shown). .
Further, since thecylindrical fastening member 15 is formed from a flexible material and theinsertion coil 32 is bendable, these members can be retained in the forceps channel C even when theinsertion portion 21 is bent. It can move smoothly.

操作装置30の先端が鉗子チャンネルCの先端部に到達したら、鉗子口24から突出している操作ワイヤ35の基端部を掴んで、操作ワイヤ35を操作してフック部34のみを内視鏡20の先端面22から突出させ、このフック部34に牽引分離部材14の鈎部14cを係合して、操作ワイヤ35を操作部側に引く。すると、図7に示すように、筒状締付部材15の基端部が規制管33の大径部33aに嵌合するとともに、牽引連結部材14、筒状締付部材15、及び磁性把持部材11の基部12が鉗子チャンネルC内に引き込まれ、磁気アンカー装置10と操作装置30が一体化する。  When the distal end of theoperation device 30 reaches the distal end portion of the forceps channel C, the proximal end portion of theoperation wire 35 protruding from the forceps opening 24 is grasped, and theoperation wire 35 is operated so that only thehook portion 34 isendoscope 20. Theoperation wire 35 is pulled toward the operation portion side by engaging thehook portion 34 with thehook portion 14 c of the pullingseparation member 14. Then, as shown in FIG. 7, the proximal end portion of thecylindrical fastening member 15 is fitted to thelarge diameter portion 33 a of therestriction tube 33, and thetraction connecting member 14, thecylindrical fastening member 15, and the magnetic grippingmember 11base 12 is drawn into the forceps channel C, and themagnetic anchor device 10 and the operatingdevice 30 are integrated.

このように、内視鏡20に磁気アンカー装置10と操作装置30をセットしたら、図8に示すように、挿入コイル32の基端部を掴みながら挿入コイル32を挿入部21の先端側に移動させて、磁性把持部材11を病変部Xに近接させる。この状態で操作ワイヤ35を内視鏡20に対して相対的に後方に引くと、磁性把持部材11の基部12が筒状締付部材15内に引き込まれ、磁性把持部材11は図8に示す開状態となる。  When themagnetic anchor device 10 and the operatingdevice 30 are set in theendoscope 20 as described above, theinsertion coil 32 is moved to the distal end side of theinsertion portion 21 while grasping the proximal end portion of theinsertion coil 32 as shown in FIG. Thus, the magnetic grippingmember 11 is brought close to the lesioned part X. When theoperation wire 35 is pulled rearward relative to theendoscope 20 in this state, thebase 12 of the magnetic grippingmember 11 is pulled into thecylindrical fastening member 15, and the magnetic grippingmember 11 is shown in FIG. Open state.

さらに操作ワイヤ35を後方に引くと、磁性把持部材11の基部12が筒状締付部材15内部の後方にさらに引き込まれ、かつ、傾斜片13aが筒状締付部材15の先端開口部に当接するので、磁性把持部材11の中間片13bが閉じて、両爪部13cにより病変部Xが確実に把持される(図9参照)。  When theoperation wire 35 is further pulled rearward, thebase 12 of the magnetic grippingmember 11 is further pulled rearward inside thecylindrical fastening member 15, and theinclined piece 13 a contacts the distal end opening of thecylindrical fastening member 15. Therefore, theintermediate piece 13b of the magnetic grippingmember 11 is closed, and the lesioned part X is securely gripped by the bothclaws 13c (see FIG. 9).

この状態で、操作ワイヤ35を上記切断力以上の強い力で後方に引くと、フック部34と係合している牽引分離部材14が、その中間部で切断され、その結果、磁気アンカー装置10が操作ワイヤ35から分離する(図10参照)。  In this state, when theoperation wire 35 is pulled backward with a force greater than the above cutting force, thetraction separating member 14 engaged with thehook portion 34 is cut at the intermediate portion, and as a result, themagnetic anchor device 10 Is separated from the operation wire 35 (see FIG. 10).

続いて、図11に示すように、患者Aの体外に配置されている磁気誘導部材46の発生磁界を強める。磁性把持部材11に生じる吸引力は磁性把持部材11の体積と密接な関係があり、磁性把持部材11の体積が大きいほど吸引力も大きくなる。例えば、磁性把持部材(材質は磁性SUS)11の寸法を、外形10mm、長さ17mm、体積754mm3とすると、磁気誘導部材46が発生する磁界の強さが0.604kOe(キロエルステッド)で、かつ、磁気誘導部材46から磁性把持部材11までの距離が10.5cmの場合、磁性把持部材11には12.1gの吸引力が生じる。
このように、磁性把持部材11の体積を所定の大きさ以上にすれば、磁性把持部材11には図11の上側を向く十分な大きさの吸引力が掛かり、磁性把持部材11に掴まれている病変部Xも同方向に十分な距離だけ持ち上げられる。
Subsequently, as shown in FIG. 11, the generated magnetic field of themagnetic induction member 46 arranged outside the body of the patient A is strengthened. The attractive force generated in the magnetic grippingmember 11 is closely related to the volume of the magnetic grippingmember 11, and the attractive force increases as the volume of the magnetic grippingmember 11 increases. For example, if the dimensions of the magnetic gripping member (material is magnetic SUS) 11 are an outer shape of 10 mm, a length of 17 mm, and a volume of 754 mm3 , the strength of the magnetic field generated by themagnetic induction member 46 is 0.604 kOe (kiloelsted) In addition, when the distance from themagnetic induction member 46 to the magnetic grippingmember 11 is 10.5 cm, an attractive force of 12.1 g is generated in the magnetic grippingmember 11.
As described above, when the volume of the magnetic grippingmember 11 is set to a predetermined size or more, the magnetic grippingmember 11 is applied with a sufficiently large attractive force facing upward in FIG. 11 and is gripped by the magnetic grippingmember 11. The existing lesion X is also lifted by a sufficient distance in the same direction.

このように、病変部Xを所望方向に所望距離だけ移動させると、病変部Xと正常組織との境界部に、十分な大きさの切除部分が形成されるので、挿入管31、挿入コイル32、及び操作ワイヤ35を内視鏡20から取り出し、図11に示すように、内視鏡20(図11では図示略)の鉗子チャネルCを利用して高周波メス50などの切開具を臓器B内に挿入し、病変部Xを粘膜とともに一方の端部側から切除する。
そして、病変部Xを一方の端部側から反対の端部側に切除すると、やがて、病変部X全体が完全に切除される(図12参照)。
なお、高周波メス50による切除作業時においては、切除領域が拡がるにつれて、高周波メス50の先端50aの位置の確認は、より容易となる。
Thus, when the lesioned part X is moved by a desired distance in the desired direction, a sufficiently large excision part is formed at the boundary between the lesioned part X and the normal tissue. Then, theoperation wire 35 is taken out from theendoscope 20, and as shown in FIG. 11, an incision tool such as a high-frequency knife 50 is inserted into the organ B by using the forceps channel C of the endoscope 20 (not shown in FIG. 11). The lesioned part X is excised together with the mucous membrane from one end side.
Then, when the lesioned part X is excised from one end side to the opposite end side, the entire lesioned part X is eventually completely excised (see FIG. 12).
In the excision work with the high-frequency knife 50, the position of thetip 50a of the high-frequency knife 50 becomes easier to confirm as the excision area expands.

以上のように切除作業を終えると、正常組織から切り離された病変部Xは磁性把持部材11(磁気アンカー装置10)に把持されたままの状態となるので、病変部Xの紛失が防止される。
切除した病変部Xを回収するには、図12に示すように、内視鏡20(図12では図示略)の鉗子チャンネルCに、その先端部に開閉可能な一対の把持片61を具備し、さらに、その基端部に操作部(図示略)を具備する把持鉗子60を挿入する。そして、この操作部を操作して、把持片61を開放状態にした状態で牽引分離部材14に近接させ、その後に両把持片61を閉じて、両把持片61により牽引分離部材14を確実に把持する。そして、そのままの状態で内視鏡20を体内から抜き去り、病変部Xを磁気アンカー装置10とともに体外に取り出し、その後に、そして、切除した部分の縫合、消毒などの処置を行う。
When the excision work is completed as described above, the lesioned part X separated from the normal tissue remains in the state of being gripped by the magnetic gripping member 11 (magnetic anchor device 10), so that the lesioned part X is prevented from being lost. .
In order to collect the excised lesion X, as shown in FIG. 12, the forceps channel C of the endoscope 20 (not shown in FIG. 12) is provided with a pair ofgripping pieces 61 that can be opened and closed at the distal end thereof. Further, a graspingforceps 60 having an operation part (not shown) is inserted into the base end part thereof. Then, by operating this operation unit, the grippingpiece 61 is brought into the open state to be brought close to thetraction separation member 14, and then the both grippingpieces 61 are closed so that thetraction separation member 14 is securely attached by the both grippingpieces 61. Hold it. Then, theendoscope 20 is removed from the body as it is, the lesioned part X is taken out of the body together with themagnetic anchor device 10, and thereafter, the excised part is sutured and disinfected.

以上のように、本実施形態の磁気アンカー遠隔誘導システムを用いれば、磁性把持部材11が、従来の磁気アンカー遠隔誘導システムの磁気アンカーと把持部材の両方の機能を兼ねるので、従来の磁気アンカー遠隔誘導システムに比べて、部品点数の減少を図ることができ、磁気アンカー装置10の組み立て作業を容易に行うことができる。  As described above, when the magnetic anchor remote guidance system of this embodiment is used, the magnetic grippingmember 11 functions as both the magnetic anchor and the gripping member of the conventional magnetic anchor remote guidance system. Compared to the guidance system, the number of parts can be reduced, and the assembly work of themagnetic anchor device 10 can be easily performed.

さらに、従来の磁気アンカー遠隔誘導システムでは連結ひも(連結部材)を必要としており、磁気誘導部材46から磁界を発生させると、磁気アンカーが臓器の内壁に接触するものの、連結ひもが緊張せず、その結果、把持部材に牽引力が掛からないということがあったが、本実施形態では連結ひも(連結部材)が不要となので、磁気誘導部材46から磁界を発生させれば、病変部Xを所望の方向に所望の距離だけ確実に移動させることができる。  Furthermore, the conventional magnetic anchor remote guidance system requires a connection string (connection member). When a magnetic field is generated from themagnetic induction member 46, the magnetic anchor contacts the inner wall of the organ, but the connection string does not become tensioned. As a result, there is a case where no traction force is applied to the gripping member. However, in the present embodiment, a connecting string (connecting member) is not required. It can be reliably moved by a desired distance in the direction.

さらに、病変部Xを所望方向に十分な距離だけ移動させることができるため、病変部Xと正常組織との境界の切除部分を、容易かつ確実に十分な大きさで確保することができる。また、病変部Xが扁平な形状であっても、十分な大きさの切除部分を作りだすことができるので、このような場合であっても、病変部Xを容易に切除することが可能となる。  Further, since the lesioned part X can be moved in a desired direction by a sufficient distance, the excised part at the boundary between the lesioned part X and the normal tissue can be easily and reliably secured with a sufficient size. Even if the lesioned part X has a flat shape, a sufficiently large excision part can be created. Even in such a case, the lesioned part X can be easily excised. .

さらに、病変部Xは磁性把持部材11により持ち上げられるため、切除部分を十分確保することができ、すでに切除した病変部Xが固有筋層B2上に落ち込むことを防止できる。
また、任意の位置に磁性把持部材11を配置できるため、切除した病変部Xにより内視鏡20の視界が妨げられることがない。
Furthermore, since the lesioned part X is lifted by the magnetic grippingmember 11, a sufficiently excised part can be secured, and the already excised lesioned part X can be prevented from falling on the proper muscle layer B2.
Further, since the magnetic grippingmember 11 can be arranged at an arbitrary position, the view of theendoscope 20 is not hindered by the excised lesioned part X.

本発明について上記実施形態を参照しつつ説明したが、本発明は上記実施形態に限定されるものではなく、改良の目的または本発明の思想の範囲内において改良または変更が可能である。例えば、基部12の形状を変更した上で、傾斜片13aと中間片13bと爪部13cの一体物を3個以上としてもよい。このようにすれば、磁性把持部材11の体積が大きくなるので、磁性把持部材11に掛かる吸引力が大きくなる。  Although the present invention has been described with reference to the above embodiment, the present invention is not limited to the above embodiment, and can be improved or changed within the scope of the purpose of the improvement or the idea of the present invention. For example, after changing the shape of thebase part 12, it is good also as three or more integrated objects of theinclination piece 13a, theintermediate piece 13b, and the nail | clawpart 13c. In this way, since the volume of the magnetic grippingmember 11 is increased, the attractive force applied to the magnetic grippingmember 11 is increased.
