Description

本発明はバルーン装着ジグ及びそれを用いたバルーン装着方法に係り、特に内視鏡の挿入部或いは挿入補助具にバルーンを装着するためのバルーン装着ジグ、及びそれを用いたバルーン装着方法に関する。   The present invention relates to a balloon mounting jig and a balloon mounting method using the same, and more particularly to a balloon mounting jig for mounting a balloon on an insertion portion or an insertion aid of an endoscope and a balloon mounting method using the same.

内視鏡は、体腔内に挿入される挿入部を有し、この挿入部の先端部に観察光学系が設けられている。また、挿入部には湾曲部が設けられており、この湾曲部を湾曲操作することによって、先端部の観察光学系を所望する方向に向けることができる。これにより、体腔内の所望する位置を観察することができる。   The endoscope has an insertion portion to be inserted into a body cavity, and an observation optical system is provided at the distal end portion of the insertion portion. In addition, the insertion portion is provided with a bending portion, and by operating the bending portion, the observation optical system at the distal end portion can be directed in a desired direction. Thereby, a desired position in the body cavity can be observed.

ところで、挿入部の外周面や、挿入部に被せられる挿入補助具の外周面にバルーンが装着された内視鏡装置が開発されている。この内視鏡装置によれば、バルーンを膨張させることによって、挿入部や挿入補助具が体腔内に固定され、挿入部の先端部を所望する方向に向けて固定することができる。前記バルーンは、略筒状に形成されており、挿入部や挿入補助具が挿通した状態で固定される。したがって、バルーンを装着する際は、バルーンを外側に拡げながら、挿入部や挿入補助具を挿通させる必要があり、このために、バルーンの装着作業に手間がかかるという問題があった。   By the way, an endoscope apparatus has been developed in which a balloon is mounted on the outer peripheral surface of the insertion portion or the outer peripheral surface of an insertion assisting tool that covers the insertion portion. According to this endoscope apparatus, by inflating the balloon, the insertion portion and the insertion assisting tool are fixed in the body cavity, and the distal end portion of the insertion portion can be fixed in a desired direction. The said balloon is formed in the substantially cylindrical shape, and is fixed in the state which the insertion part and the insertion auxiliary tool penetrated. Therefore, when the balloon is mounted, it is necessary to insert the insertion portion and the insertion assisting tool while expanding the balloon to the outside, which causes a problem that it takes time to mount the balloon.

特許文献１には、バルーンを筒体の内周面に吸着する装着方法が記載されている。この方法によれば、筒体の内周面にバルーンを吸着することによってバルーンの内径を拡げることができ、挿入部や挿入補助具を簡単に挿通させることができる。しかし、この方法は、専用の吸引装置が必要となるという問題がある。   Patent Document 1 describes a mounting method for adsorbing a balloon to the inner peripheral surface of a cylindrical body. According to this method, the inner diameter of the balloon can be expanded by adsorbing the balloon to the inner peripheral surface of the cylinder, and the insertion portion and the insertion aid can be easily inserted. However, this method has a problem that a dedicated suction device is required.

特許文献２には、管状のジグ本体と、ジグ本体の基端に螺合された締め金具を用いて、筒状の湾曲ゴムを装着する方法が記載されている。ジグ本体は、締め金具を締め込むことによって、先端部が細径化される。したがって、細経化されたジグ本体の先端部に湾曲ゴムを被せた後、締め金具を緩めてジグ本体の先端部の径を大きくすれば、湾曲ゴムの内径を拡げることができ、挿入部を簡単に挿入することができる。
特開平５−１５４８７号公報 特開平９−３０８６０５号公報 Patent Document 2 describes a method of mounting a tubular curved rubber using a tubular jig body and a fastener that is screwed to the base end of the jig body. The tip of the jig body is reduced in diameter by tightening the fasteners. Therefore, after covering the tip of the jig main body with the curved rubber, loosening the fasteners and increasing the diameter of the tip of the jig main body, the inner diameter of the curved rubber can be expanded, and the insertion portion Easy to insert.
Japanese Patent Laid-Open No. 5-15487 JP-A-9-308605

しかしながら、特許文献２は、湾曲ゴムを装着した後に、挿入部や挿入補助具をジグ本体から引き抜く必要があり、その際にジグ本体が湾曲ゴムに接触して湾曲ゴムを損傷するおそれがあった。このため、挿入部や挿入補助具を引き抜く作業を慎重に行わねばならず、手間がかかるという問題があった。   However, in Patent Document 2, it is necessary to pull out the insertion portion and the insertion assisting tool from the jig main body after attaching the curved rubber, and in that case, the jig main body may contact the curved rubber and damage the curved rubber. . For this reason, the operation of pulling out the insertion portion and the insertion assisting tool has to be performed carefully, and there is a problem that it takes time.

本発明はこのような事情に鑑みてなされたもので、内視鏡の挿入部や挿入補助具にバルーンを簡単に装着することのできるバルーン装着ジグ及びそれを用いたバルーン装着方法を提供することを目的とする。   The present invention has been made in view of such circumstances, and provides a balloon mounting jig capable of easily mounting a balloon on an insertion portion or an insertion aid of an endoscope and a balloon mounting method using the same. With the goal.

A balloon mounting jig for mounting the balloon to the insertion portion or the insertion assisting tool includes a pair of semi-cylindrical members formed in a semi-cylindrical shape and rotatably combined in a circumferential direction. By overlapping the positions of the semi-cylindrical members, a semi-cylindrical body to be inserted into the opening of the balloon is formed, and the pair of semi-cylindrical members are relatively rotated in the circumferential direction to thereby insert the semi-cylindrical member. A cylindrical body having an inner diameter larger than the outer diameter of the portion or the outer diameter of the insertion assisting tool is formed.

請求項２に記載の発明は前記目的を達成するために、請求項１に記載のバルーン装着ジグを用いて内視鏡の挿入部または挿入補助具にバルーンを装着するバルーン装着方法において、前記一対の半円筒部材を重ね合わせて半筒体を形成して前記バルーンの開口部に挿入し、該挿入した一対の半円筒部材を円周方向に相対的に回動させて筒体を形成することによって前記バルーンの開口部を拡径し、前記挿入部または前記挿入補助具を前記筒体に挿入することによって前記バルーンを前記挿入部または前記挿入補助具の装着位置に配置し、前記一対の半円筒部材を重ね合わせて半筒体を形成して前記バルーンの開口部から引き抜くことを特徴としている。   In order to achieve the above object, a second aspect of the present invention provides a balloon mounting method in which a balloon is mounted on an insertion portion or an insertion aid of an endoscope using the balloon mounting jig according to the first aspect. A semi-cylindrical member is formed by overlapping the half-cylindrical members and inserted into the opening of the balloon, and the pair of semi-cylindrical members inserted are rotated relative to each other in the circumferential direction to form the cylindrical body. The diameter of the opening of the balloon is expanded by the step of inserting the insertion portion or the insertion assisting tool into the cylindrical body, thereby placing the balloon at the mounting position of the insertion portion or the insertion assisting tool. A cylindrical member is overlapped to form a semi-cylindrical body and is drawn out from the opening of the balloon.

請求項１に記載の発明によれば、一対の半円筒部材が円周方向に回動自在に組み合わされているので、一対の半円筒部材を円周方向にずらして筒体を形成したり、重ね合わせて半筒体を形成したりすることができる。したがって、請求項２に記載の如く、半筒体の状態でバルーンの開口部に挿入した後、筒体を形成することによって、バルーンの開口部を拡げることができ、挿入部や挿入補助具をバルーンの開口部に容易に挿入することができる。これにより、バルーンを挿入部や挿入補助具に容易に装着することができる。   According to the invention of claim 1, since the pair of semi-cylindrical members are combined so as to be rotatable in the circumferential direction, the pair of semi-cylindrical members are shifted in the circumferential direction to form a cylinder, A half cylinder can be formed by superimposing. Therefore, as described in claim 2, after being inserted into the opening of the balloon in a semi-cylindrical state, the opening of the balloon can be expanded by forming the cylinder, and the insertion portion and the insertion aid can be It can be easily inserted into the opening of the balloon. Thereby, a balloon can be easily attached to an insertion part or an insertion aid.

また、請求項１に記載の発明によれば、バルーンを装着した後に、バルーン装着ジグを半筒体にしてバルーンから引き抜くことによって、バルーン装着ジグをバルーンに接触させることなく、容易に取り外すことができる。   In addition, according to the first aspect of the present invention, after the balloon is mounted, the balloon mounting jig can be easily removed without making contact with the balloon by pulling the balloon mounting jig into a semi-cylindrical body and pulling it out from the balloon. it can.

本発明に係るバルーン装着ジグ及びそれを用いたバルーン装着方法によれば、一対の半円筒部材が円周方向に摺動自在に組み合わされているので、バルーンの開口部に挿入しやすい半筒体にしたり、バルーンの開口部を拡げることができる筒体にしたりすることができ、バルーンの装着作業を容易に行うことができる。また、バルーンの装着後に半筒体にすることによって、バルーン装着ジグを挿入部や挿入補助具から容易に取り外すことができる。   According to the balloon mounting jig and the balloon mounting method using the same according to the present invention, since the pair of semi-cylindrical members are slidably combined in the circumferential direction, the semi-cylindrical body that can be easily inserted into the opening of the balloon Or a cylindrical body capable of expanding the opening of the balloon, and the balloon can be easily attached. In addition, the balloon mounting jig can be easily removed from the insertion portion and the insertion assisting tool by forming the half cylinder after the balloon is mounted.

以下添付図面に従って本発明に係るバルーン装着ジグ及びそれを用いたバルーン装着方法の好ましい実施の形態について説明する。   Preferred embodiments of a balloon mounting jig and a balloon mounting method using the same according to the present invention will be described below with reference to the accompanying drawings.

まず、本実施の形態の装着ジグによって装着されるバルーンと、そのバルーンが装着される内視鏡の挿入部について説明する。なお、以下は、バルーンを内視鏡の挿入部に装着する例で説明するが、これに限定するものではなく、挿入部を体腔内に挿入するための挿入補助具にバルーンを装着してもよい。   First, a balloon to be mounted by the mounting jig of the present embodiment and an insertion portion of an endoscope to which the balloon is mounted will be described. In the following, an example in which a balloon is attached to an insertion portion of an endoscope will be described. However, the present invention is not limited to this, and the balloon may be attached to an insertion aid for inserting the insertion portion into a body cavity. Good.

図５に示すように、バルーン１２は、ゴム等の弾性体から成り、両端が絞られた略筒状に形成されている。すなわち、バルーン１２は、両端の固定部（開口部に相当）１２Ａ、１２Ａと、中央の膨張部１２Ｂとを備えている。固定部１２Ａはその内径Ｄ２が挿入部１４の外径Ｄ３よりも小さく形成されている。したがって、図５に二点鎖線で示すように、挿入部１４をバルーン１２に挿入すると、バルーン１２の固定部１２Ａ、１２Ａがその弾性力によって縮径し、挿入部１４の外周面に密着するようになっている。この固定部１２Ａ、１２Ａに糸を巻回したり、固定リングを嵌挿することによって、バルーン１２が挿入部１４に装着される。装着されたバルーン１２は、内部にエアを供給することによって膨張部１２Ｂが膨張するとともに、内部からエアを吸引することによって膨張部１２Ｂが挿入部１４の外周面に張り付くようになっている。なお、バルーン１２の形状は、上述した例に限定されるものではなく、例えば、全体が円筒状に形成されたバルーンや、開口部が一つのみのバルーン等であってもよい。   As shown in FIG. 5, the balloon 12 is made of an elastic body such as rubber and is formed in a substantially cylindrical shape with both ends narrowed. That is, the balloon 12 includes fixed portions (corresponding to openings) 12A and 12A at both ends, and a central inflatable portion 12B. The fixed portion 12 </ b> A has an inner diameter D <b> 2 smaller than an outer diameter D <b> 3 of the insertion portion 14. Therefore, as shown by a two-dot chain line in FIG. 5, when the insertion portion 14 is inserted into the balloon 12, the fixing portions 12 </ b> A and 12 </ b> A of the balloon 12 are reduced in diameter by the elastic force so as to be in close contact with the outer peripheral surface of the insertion portion 14. It has become. The balloon 12 is attached to the insertion portion 14 by winding a thread around the fixing portions 12A and 12A or by inserting a fixing ring. The inflated portion 12B is inflated by supplying air to the inside of the attached balloon 12, and the inflatable portion 12B sticks to the outer peripheral surface of the insertion portion 14 by sucking air from the inside. The shape of the balloon 12 is not limited to the example described above, and may be, for example, a balloon formed entirely in a cylindrical shape, a balloon having only one opening, or the like.

本発明に係るバルーン装着ジグは、上記の如く構成されたバルーン１２を挿入部１４に被せる際に使用されるジグである。図１及び図２は、本発明に係る装着ジグ１０を示す斜視図である。図１は筒状の状態の装着ジグ１０を示し、図２は半筒体の状態の装着ジグ１０を示している。また、図３は、装着ジグ１０の分解斜視図であり、図４は、図１に示す装着ジグ１０の側面図である。   The balloon mounting jig according to the present invention is a jig used when the insertion portion 14 is covered with the balloon 12 configured as described above. 1 and 2 are perspective views showing a mounting jig 10 according to the present invention. FIG. 1 shows the mounting jig 10 in a cylindrical state, and FIG. 2 shows the mounting jig 10 in a semi-cylindrical state. 3 is an exploded perspective view of the mounting jig 10, and FIG. 4 is a side view of the mounting jig 10 shown in FIG.

これらの図に示すように、装着ジグ１０は、ジグ本体１６、及び回転体１８で構成される。   As shown in these drawings, the mounting jig 10 includes a jig body 16 and a rotating body 18.

回転体１８は、図３に示すように半円筒状（すなわち、円筒形状のものを、円筒の軸を通る平面で分断した形状）に形成されており、その内径Ｄ０は前述した挿入部１４の外径Ｄ３（図５参照）よりも大きく形成されている。回転体１８の基端部１８Ａは大きく折り返されており、後述するジグ本体１６の基端部１６Ａを包み込めるようになっている。基端部１８Ａには、摘まみ部２０が突出形成されており、回転体１８を回転する際に作業者が指をかけやすいようになっている。また、回転体１８は、折り返された基端部１６Ａを除く部分の長さＬ０が、前述したバルーン１２の固定部１２Ａの長さＬ２（図５参照）よりも長く形成されている。   The rotating body 18 is formed in a semi-cylindrical shape (that is, a shape obtained by dividing a cylindrical shape by a plane passing through the axis of the cylinder) as shown in FIG. It is formed larger than the outer diameter D3 (see FIG. 5). A base end portion 18A of the rotating body 18 is largely folded back so as to wrap a base end portion 16A of a jig body 16 to be described later. A knob portion 20 is formed to protrude from the base end portion 18 </ b> A so that an operator can easily put a finger on the rotating body 18. Further, the rotating body 18 is formed such that the length L0 of the portion excluding the folded base end portion 16A is longer than the length L2 (see FIG. 5) of the fixing portion 12A of the balloon 12 described above.

一方、ジグ本体１６は、略半円筒状に形成されており、その内径Ｄ１は、回転体１８の板厚の分だけ、回転体１８の内径Ｄ０よりも大きく形成されている。したがって、ジグ本体１６の内周面と回転体１８の外周面とが接した状態で、ジグ本体１６と回転体１８とを重ね合わせることができる。なお、ジグ本体１６の内周面と回転体１８の外周面は、摺動しやすい材質で形成することが好ましい。例えば、ジグ本体１６と回転体１８とを、ポリテトラフルオロエチレン等のフッ素樹脂で形成することが好ましい。   On the other hand, the jig body 16 is formed in a substantially semi-cylindrical shape, and its inner diameter D1 is larger than the inner diameter D0 of the rotating body 18 by the thickness of the rotating body 18. Therefore, the jig body 16 and the rotating body 18 can be overlapped with each other while the inner peripheral surface of the jig body 16 and the outer peripheral surface of the rotating body 18 are in contact with each other. In addition, it is preferable to form the inner peripheral surface of the jig body 16 and the outer peripheral surface of the rotating body 18 with a material that easily slides. For example, it is preferable to form the jig body 16 and the rotating body 18 with a fluororesin such as polytetrafluoroethylene.

ジグ本体１６は、一定幅の部分の長さＬ１が回転体１８の長さＬ０よりも長く形成されている。そして、ジグ本体１６の先端部１６Ｂは、先細形状に形成されるとともに、その先端が丸みを帯びている。したがって、ジグ本体１６の先端部１６Ｂをバルーン１２の固定部１２Ａに容易に挿入することができるとともに、その挿入の際にバルーン１２が傷つくことを防止できる。   The jig body 16 is formed such that a portion L1 having a constant width is longer than a length L0 of the rotating body 18. And the front-end | tip part 16B of the jig main body 16 is formed in a tapered shape, and the front-end | tip is roundish. Therefore, the distal end portion 16B of the jig body 16 can be easily inserted into the fixed portion 12A of the balloon 12, and the balloon 12 can be prevented from being damaged during the insertion.

ジグ本体１６の基端部１６Ａは小さく折り返されており、この基端部１６Ａを包み込むようにして、回転体１８の基端部１８Ａが折り返される。これにより、基端部１６Ａと基端部１８Ａが係合され、回転体１８がジグ本体１６に対して円周方向に回動することができる。   The base end portion 16A of the jig body 16 is folded back small, and the base end portion 18A of the rotating body 18 is folded back so as to wrap around the base end portion 16A. Thereby, the base end portion 16 </ b> A and the base end portion 18 </ b> A are engaged, and the rotating body 18 can rotate in the circumferential direction with respect to the jig main body 16.

図４に示すように、ジグ本体１６は、円周方向において１８０°よりも若干大きく形成されている。したがって、ジグ本体１６と回転体１８とを一旦組み合わせると、回転体１８をジグ本体１６に対して回転させても、回転体１８はジグ本体１６から脱落しなくなる。なお、ジグ本体１６の代わりに、回転体１８を円周方向に大きく形成してもよい。   As shown in FIG. 4, the jig body 16 is formed to be slightly larger than 180 ° in the circumferential direction. Therefore, once the jig body 16 and the rotating body 18 are combined, the rotating body 18 will not fall off the jig body 16 even if the rotating body 18 is rotated relative to the jig body 16. Instead of the jig body 16, the rotating body 18 may be formed large in the circumferential direction.

上述したように、装着ジグ１０は、ジグ本体１６と回転体１８とが円周方向に回動自在に組み合わされている。したがって、図１に示すようにジグ本体１６と回転体１８との位置をずらして筒体を形成したり、図２に示すようにジグ本体１６と回転体１８とを重ね合わせて略半筒体を形成したりすることができる。   As described above, in the mounting jig 10, the jig main body 16 and the rotating body 18 are combined so as to be rotatable in the circumferential direction. Accordingly, the cylindrical body is formed by shifting the positions of the jig body 16 and the rotating body 18 as shown in FIG. 1, or the jig body 16 and the rotating body 18 are overlapped as shown in FIG. Can be formed.

次に上記の如く構成された装着ジグ１０を用いてバルーン１２を装着する方法について説明する。   Next, a method for mounting the balloon 12 using the mounting jig 10 configured as described above will be described.

まず、図２に示す如く、装着ジグ１０を半筒体にする。そして、ジグ本体１６の先端部１６Ｂをバルーン１２の固定部１２Ａに挿入する。このとき、ジグ本体１６の先端部１６Ｂが先細形状であるので、ジグ本体１６の先端部１６Ｂをバルーン１２の固定部１２Ａに容易に挿入することができる。また、装着ジグ１０が半筒体なので、図６（Ａ）に示すように、装着ジグ１０をバルーン１２の固定部１２Ａの奥まで容易に挿入することができる。   First, as shown in FIG. 2, the mounting jig 10 is formed into a half cylinder. Then, the distal end portion 16B of the jig body 16 is inserted into the fixing portion 12A of the balloon 12. At this time, since the distal end portion 16B of the jig body 16 has a tapered shape, the distal end portion 16B of the jig body 16 can be easily inserted into the fixing portion 12A of the balloon 12. Further, since the mounting jig 10 is a half cylinder, the mounting jig 10 can be easily inserted to the back of the fixing portion 12A of the balloon 12 as shown in FIG.

装着ジグ１０をバルーン１２の奥まで挿入した後、回転体１８をジグ本体１６に対して回転させ、図６（Ｂ）に示すように装着ジグ１０を筒体の状態にする。これにより、バルーン１２の固定部１２Ａは、ジグ本体１６と回転体１８によって拡径され、挿入部１４の外径Ｄ３よりも大きく拡げられる。その際、ジグ本体１６の内側の回転体１８を回転させるので、バルーン１２の固定部１２Ａに無理な負荷をかけることなく、容易に拡げることができる。また、回転体１８の長さＬ０（図３参照）が固定部１２Ａの長さＬ２（図５参照）よりも大きいので、固定部１２Ａ全体を拡げることができる。   After inserting the mounting jig 10 to the back of the balloon 12, the rotating body 18 is rotated with respect to the jig main body 16, and the mounting jig 10 is brought into a cylindrical state as shown in FIG. Thereby, the fixing portion 12A of the balloon 12 is expanded in diameter by the jig body 16 and the rotating body 18, and is expanded to be larger than the outer diameter D3 of the insertion portion 14. At this time, since the rotating body 18 inside the jig body 16 is rotated, it can be easily expanded without imposing an excessive load on the fixing portion 12A of the balloon 12. Further, since the length L0 (see FIG. 3) of the rotating body 18 is larger than the length L2 (see FIG. 5) of the fixed portion 12A, the entire fixed portion 12A can be expanded.

次に、装着ジグ１０の内部に挿入部１４を挿入する。その際、固定部１２Ａが拡げられているので、挿入部１４を固定部１２Ａに容易に挿入することができる。挿入部１４をバルーン１２の内部に挿入していくと、もう一方の固定部１２Ａは挿入部１４が挿通されて自然に押し広げられる。これにより、挿入部１４をバルーン１２に挿通させることができる。   Next, the insertion portion 14 is inserted into the mounting jig 10. At that time, since the fixing portion 12A is expanded, the insertion portion 14 can be easily inserted into the fixing portion 12A. When the insertion portion 14 is inserted into the balloon 12, the other fixing portion 12A is naturally pushed out by the insertion portion 14 being inserted. Thereby, the insertion portion 14 can be inserted through the balloon 12.

バルーン１２が所定の位置に配置された後、装着ジグ１０の回転体１８をジグ本体１６に対して相対的に回転させ、図６（Ｃ）に示すように装着ジグ１０を半筒体にする。これにより、固定部１２Ａの一部が挿入部１４の外周面に密着する。作業者は、この密着部分を指で押さえながら、半筒体の装着ジグ１０を固定部１２Ａから引き抜く。このとき、装着ジグ１０を半筒体としたことによって固定部１２Ａの膨張度合いが低下しているので、装着ジグ１０を容易に引き抜くことができる。また、引き抜いた装着ジグ１０は、半筒体であるので、挿入部１４に対して容易に取り外すことができる。したがって、装着ジグ１０を挿入部１４から引き抜く必要がないので、装着後のバルーン１２を装着ジグ１０によって傷つけるおそれがない。   After the balloon 12 is disposed at a predetermined position, the rotating body 18 of the mounting jig 10 is rotated relative to the jig main body 16 to make the mounting jig 10 a half cylinder as shown in FIG. . Thereby, a part of the fixing portion 12 </ b> A comes into close contact with the outer peripheral surface of the insertion portion 14. The operator pulls out the semi-cylindrical mounting jig 10 from the fixing portion 12A while pressing the contact portion with a finger. At this time, since the mounting jig 10 is a semi-cylindrical body, the degree of expansion of the fixed portion 12A is reduced, so that the mounting jig 10 can be easily pulled out. Further, since the extracted mounting jig 10 is a semi-cylindrical body, it can be easily removed from the insertion portion 14. Therefore, there is no need to pull out the mounting jig 10 from the insertion portion 14, and there is no possibility that the balloon 12 after mounting will be damaged by the mounting jig 10.

このように本実施の形態の装着ジグ１０によれば、ジグ本体１６と回転体１８とを相対的に回転させることによって装着ジグ１０が半筒体や筒体になるので、バルーン１２の装着作業を容易に行うことができる。すなわち、装着ジグ１０を半筒体とすることによって装着ジグ１０をバルーン１２の固定部１２Ａに容易に挿入することができ、挿入後に装着ジグ１０を筒体とすることによって固定部１２Ａに挿入部１４を容易に挿入することができ、さらに挿入後に装着ジグ１０を半筒体とすることによって装着ジグ１０をバルーン１２から容易に引き抜くことができる。よってバルーン１２の装着作業を容易に行うことができる。   As described above, according to the mounting jig 10 of the present embodiment, the mounting jig 10 becomes a semi-cylindrical body or a cylindrical body by relatively rotating the jig main body 16 and the rotating body 18. Can be easily performed. That is, the mounting jig 10 can be easily inserted into the fixing portion 12A of the balloon 12 by making the mounting jig 10 into a semi-cylindrical body, and the insertion portion can be inserted into the fixing portion 12A by using the mounting jig 10 as a cylindrical body after insertion. 14 can be inserted easily, and the mounting jig 10 can be easily pulled out of the balloon 12 by making the mounting jig 10 into a half cylinder after insertion. Therefore, the mounting operation of the balloon 12 can be easily performed.

また、本実施の形態によれば、バルーン１２の装着後に、装着ジグ１０が半筒体になっているので、装着ジグ１０を挿入部１２から容易に取り外すことができる。よって、装着後のバルーン１２を装着ジグ１０によって傷つけることを防止することができる。また、バルーン１２を挿入部１４の先端から離れた位置に装着した場合であっても、装着ジグ１０を容易に取り外すことができる。   Further, according to the present embodiment, since the mounting jig 10 is a semi-cylindrical body after the balloon 12 is mounted, the mounting jig 10 can be easily detached from the insertion portion 12. Therefore, it is possible to prevent the mounted balloon 10 from being damaged by the mounting jig 10. Even when the balloon 12 is mounted at a position away from the distal end of the insertion portion 14, the mounting jig 10 can be easily removed.

なお、上述した実施の形態は、装着ジグ１０をバルーン１２の固定部１２Ａから引き抜く際に、装着ジグ１０を半筒体の状態にしたが、これに限定するものではなく、装着ジグ１０が筒体の状態のまま、固定部１２Ａから引き抜いてもよい。この場合には、引き抜いた後に装着ジグ１０を半筒体にすることによって、容易に挿入部１４から取り外すことができる。   In the above-described embodiment, when the mounting jig 10 is pulled out from the fixing portion 12A of the balloon 12, the mounting jig 10 is in a semi-cylindrical state. However, the present invention is not limited to this. You may pull out from the fixing | fixed part 12A with a body state. In this case, it is possible to easily remove the mounting jig 10 from the insertion portion 14 by making the mounting jig 10 into a semi-cylindrical body after being pulled out.

また、上述した実施の形態は、バルーン１２の一方の固定部１２Ａのみに装着ジグ１０を取り付けたが、これに限定するものではなく、もう一方の固定部１２Ａに装着ジグ１０を取り付けてもよい。この場合、両方の固定部１２Ａ、１２Ａが拡げられるので、挿入部１４をより簡単にバルーン１２に挿通させることができる。   In the embodiment described above, the mounting jig 10 is attached only to one fixing part 12A of the balloon 12. However, the present invention is not limited to this, and the mounting jig 10 may be attached to the other fixing part 12A. . In this case, since both the fixing portions 12A and 12A are expanded, the insertion portion 14 can be more easily inserted into the balloon 12.
