Description

本発明はカテーテル等の挿入を案内するガイドワイヤーを支持するホルダー全 般に関するものである。   The present invention relates to a general holder for supporting a guide wire for guiding insertion of a catheter or the like.

従来、ガイドワイヤーを支持するホルダーは、一般的には図３のように樹脂製のチューブを渦巻き状円形にした後、その形状を維持するため隣接するチューブを固定具で固定して、ガイドワイヤーを挿入している（例えば、特許文献１及び２）。特に全長が長いガイドワイヤーにおいては、メーカーで樹脂製のチューブにガイドワイヤーを挿入する時、及び手術時に樹脂製のチューブから一旦出したガイドワイヤーを樹脂製のチューブに納めようとするときの挿入抵抗が大きくなるため、渦巻き状円形の外径を大きくして挿入抵抗を小さくし、操作性に支障が出ないように製造しているが、外径の大きさに応じた製品箱（角型）が必要となるため、輸送コスト、持ち運び、保管場所に問題があった。   Conventionally, a holder for supporting a guide wire is generally formed by winding a resin tube into a spiral shape as shown in FIG. 3, and then fixing the adjacent tube with a fixture in order to maintain the shape. (For example, Patent Documents 1 and 2). Especially for guidewires with a long overall length, the insertion resistance when a manufacturer inserts a guidewire into a resin tube and when the guidewire once pulled out of the resin tube during surgery is to be placed in the resin tube. Therefore, the outer diameter of the spiral-shaped circle is increased to reduce the insertion resistance, and it is manufactured so as not to hinder the operability, but the product box (square type) according to the size of the outer diameter Therefore, there were problems in transportation cost, carrying and storage location.

より小さな製品箱を使用するべく、図４のようにバンドでホルダーを楕円状に変形させる場合が有るが、客先での手術時に樹脂製のチューブから一旦出したガイドワイヤーを樹脂製のチューブに納めようとするときに、ホルダーの曲率が大きい位置で挿入抵抗が大きくなる問題点があった。
特開２００４−７３３６９号公報、図２〜４ 特開平９−２８５５４６号公報、図７ In order to use a smaller product box, there is a case where the holder is deformed into an oval shape with a band as shown in FIG. 4, but the guide wire once taken out from the resin tube at the time of surgery at the customer's place is changed to the resin tube. When trying to fit, there was a problem that the insertion resistance increased at a position where the curvature of the holder was large.
JP 2004-73369 A, FIGS. JP-A-9-285546, FIG.

本発明はかかる従来技術の欠点を改良し、ガイドワイヤーホルダーにおいて、 輸送・保管時はホルダーを楕円状に変形させ、外寸法のより小さな製品箱に納められるようにし、輸送コスト、営業担当者の持ち運び、病院で の保管場所専有面積を改善した。組立時及び使用時は真円状にしてガイドワイヤー挿入操作に支障がないガイドワイヤーホルダーを提供する事をその課題とする。   The present invention improves the drawbacks of the prior art, and in the guide wire holder, the holder is deformed into an oval shape during transportation and storage so that it can be stored in a product box with a smaller outer dimension. Carried and improved the area occupied by the storage area at the hospital. It is an object of the present invention to provide a guide wire holder that is perfectly circular during assembly and use and does not hinder the guide wire insertion operation.

前記課題を達成するため、本発明のガイドワイヤーホルダーは下記の構成からなる。すなわち、ガイドワイヤーを収納する保護鞘と、該保護鞘の形状を変えることができる可動固定具とを有することを特徴とするガイドワイヤーホルダーであり、好ましくは、前記可動固定具が、少なくとも固定部および可動部からり、前記可動部をスライドさせて保護鞘の形状変更することができ、保護鞘の形状変更前後のその形状を維持できる機能を持つガイドワイヤーホルダーである。   In order to achieve the above object, the guide wire holder of the present invention has the following configuration. That is, a guide wire holder comprising a protective sheath for storing a guide wire and a movable fixture that can change the shape of the protective sheath. Preferably, the movable fixture is at least a fixed portion. And a guide wire holder having a function of allowing the shape of the protective sheath to be changed by sliding the movable portion and maintaining the shape before and after the shape change of the protective sheath.

上述したように、本発明のガイドワイヤーホルダーは、その形状を変えるができ、変更前後のその形状を維持できる機能を持つため、輸送・保管時にはホルダーを楕円状に変形させ、外寸法のより小さな製品箱に納められるように出来、輸送コスト改善、持ち運びが容易、保管場所をとらない等の効果がある。また、メーカーでの組立時、及び客先での使用時は真円状にしてガイドワイヤーの保護鞘への挿入抵抗を小さく出来るため操作性が向上する。   As described above, the guide wire holder of the present invention can change its shape and maintain the shape before and after the change. Therefore, the holder is deformed into an elliptical shape during transportation and storage, and the outer dimensions are smaller. It can be stored in the product box, and has the effects of improving transportation costs, easy to carry, and not taking up storage space. In addition, when assembled at the manufacturer and when used at the customer, the insertion resistance of the guide wire to the protective sheath can be reduced to improve the operability.

図１は本発明のガイドワイヤーホルダーが真円状の渦巻き状円形である形態を示し、図２は本発明のガイドワイヤーホルダーが楕円状に変形した形態を示している。   FIG. 1 shows a form in which the guide wire holder of the present invention has a perfect spiral shape, and FIG. 2 shows a form in which the guide wire holder of the present invention is deformed into an ellipse.

図１及び図２において、１はガイドワイヤー、２はナイロン、ポリプロピレン等のガイドワイヤーとの滑り性が良い合成樹脂製保護鞘、３は合成樹脂製の可動固定具の固定側、３’は合成樹脂製の可動固定具の可動側、４は合成樹脂製の固定具、５は合成樹脂製のストッパー、６は合成樹脂製のカニューレである。本発明におけるガイドワイヤーホルダーとは保護鞘２、可動固定具３及び３’、及び、好ましくは固定具４、ストッパー５、カニューレ６を総称している。図１及び図２においてガイドワイヤー１はカニューレ６、保護鞘２の内部に挿入され、手元側端部がストッパー５で止められている。
保護鞘２は変形可能な程度の柔軟性を有する材質であればよく、ガイドワイヤーホルダーに使用されている公知の材料を使用することができるが、なかでも合成樹脂、特にナイロン、ポリプロピレン等のガイドワイヤーとの滑り性が良い合成樹脂で構成することが好ましい。ガイドワイヤーとの滑り性を向上させるために内部にコーティング等を施していてもよい。また、手術室内に持ち込まれることを考慮して、内外面に抗菌処理等を施しても良い。 1 and 2, 1 is a guide wire, 2 is a synthetic resin protective sheath that has good sliding properties with a guide wire such as nylon or polypropylene, 3 is a fixed side of a synthetic resin movable fixture, and 3 ′ is a synthetic wire The movable side of the resin movable fixture, 4 is a synthetic resin fixture, 5 is a synthetic resin stopper, and 6 is a synthetic resin cannula. The guide wire holder in the present invention is a generic term for the protective sheath 2, the movable fixtures 3 and 3 ', and preferably the fixture 4, the stopper 5, and the cannula 6. 1 and 2, the guide wire 1 is inserted into the cannula 6 and the protective sheath 2, and the proximal end is stopped by a stopper 5.
The protective sheath 2 may be any material having a degree of flexibility that can be deformed, and any known material used for the guide wire holder can be used, among which a guide made of synthetic resin, particularly nylon, polypropylene, or the like. It is preferable to use a synthetic resin that has good sliding properties with respect to the wire. In order to improve the sliding property with the guide wire, the inside may be coated. In consideration of being brought into the operating room, antibacterial treatment or the like may be applied to the inner and outer surfaces.

保護鞘２の断面形状は、目的とするガイドワイヤーを収納・挿入できる形状で有れば特に限定されないが、取り扱い性や可動固定具での固定の関係上、円形中空状が好ましい。保護鞘２の内径も目的とするガイドワイヤーを挿入できる形状であれば特に限定されないが、一般的には１ｍｍ〜１０ｍｍ程度である。保護鞘２の形状保持とガイドワイヤーを挿入した際に突き破ったりしない程度の強度を持たせるために、肉厚は０．数ｍｍ〜数ｍｍとするのが好ましい。   The cross-sectional shape of the protective sheath 2 is not particularly limited as long as it is a shape that can accommodate and insert a target guide wire, but a circular hollow shape is preferable in terms of handling and fixing with a movable fixture. Although it will not specifically limit if the inner diameter of the protective sheath 2 can also insert the target guide wire, Generally, it is about 1 mm-10 mm. In order to maintain the shape of the protective sheath 2 and to provide strength that does not break through when the guide wire is inserted, the wall thickness is 0. It is preferable to set it to several mm to several mm.

また、保護鞘２の長さは、支持するガイドワイヤーの長さに依存するが、数十ｃｍ〜数ｍである。   Moreover, although the length of the protective sheath 2 is dependent on the length of the guide wire to support, it is several dozen cm-several m.

保護鞘２はそのままでは取り扱い性、運搬性に劣るので、図１の様に渦巻き状円形に形成する。渦巻き状円形の外径は保護鞘２の長さや径に、運搬、保管に適当な大きさであれば良く、特に限定されない。   Since the protective sheath 2 is inferior in handleability and transportability as it is, it is formed in a spiral shape as shown in FIG. The outer diameter of the spiral circular shape is not particularly limited as long as it is suitable for the length and diameter of the protective sheath 2 and suitable for transportation and storage.

渦巻き状にした保護鞘２は固定具４及び可動固定具３及び３’で固定されその形状を保っている。可動固定具は、少なくとも固定部３と可動部３’とからなり、いずれの側にも保護鞘２及び／又はカニューレを固定するための固定部溝を有することが好ましい。保護鞘２と可動固定具固定部３および可動部３’の固定は、図５の様に固定部に保護鞘２を手で押し付けて固定部溝に保護鞘２を挿入し、故意に外そうとしない限り外れない構造になっている。もちろん、固定部溝以外の固定手段を用いることも可能である。   The spiral-shaped protective sheath 2 is fixed by a fixing tool 4 and movable fixing tools 3 and 3 'to keep its shape. The movable fixture is preferably composed of at least a fixed portion 3 and a movable portion 3 ′, and has a fixed portion groove for fixing the protective sheath 2 and / or the cannula on either side. As shown in FIG. 5, the protective sheath 2 and the movable fixture fixing portion 3 and the movable portion 3 ′ are fixed by manually pressing the protective sheath 2 into the fixed portion and inserting the protective sheath 2 into the fixed portion groove. Unless it is, it has a structure that does not come off. Of course, fixing means other than the fixing portion groove may be used.

固定具４の固定は、保護鞘２に固定具４を手で差し込んで固定具の溝に保護鞘２を挿入し、故意に外そうとしない限り外れない構造になっている。固定具４は可動固定具３及び３’による保護鞘２の形状の固定の補助的な役割りを果たすが、なくてもかまわない。   Fixing of the fixing tool 4 has a structure that does not come off unless the fixing tool 4 is inserted into the protective sheath 2 by hand and the protective sheath 2 is inserted into the groove of the fixing tool to intentionally remove it. The fixing device 4 plays an auxiliary role in fixing the shape of the protective sheath 2 by the movable fixing devices 3 and 3 ′, but may be omitted.

図１において可動固定具の可動部３’はスライドさせ、最大に引き出された状態で、固定部３の穴１０に可動部３’の凸部（突起）が嵌合することによって位置決めされて、その形状を保持している。図２において可動固定具の可動部３’は最大に押し込まれた状態で、穴９で位置決めされてその形状を保持している。穴９と穴１０との距離を調節することにより引き出された状態の長さ、すなわち、渦巻き状円形に形成された保護鞘２の変形度を決めることができる。複数の変形度を実現するために、穴は３つ以上あってもよい。穴及び凸部（突起）は、図５〜６のように固定具の前面に設けてもよいし、図８〜９のように側面に設けても、後面に設けてもよい。凸部（突起）は穴に嵌脱自在に設けられ、スライドさせる際は奥に押し込まれ、穴に至るとバネなどの作用により押し出され、穴に嵌合する機構になっていてもよい。また、可動固定具の引き出し状態の位置決めは、前記の穴と凸部（突起）に限らず、他の位置決め手段を用いることができる。   In FIG. 1, the movable portion 3 ′ of the movable fixture is slid and positioned in a state where the convex portion (projection) of the movable portion 3 ′ is fitted into the hole 10 of the fixed portion 3 in a state where the movable portion 3 ′ is pulled out to the maximum It retains its shape. In FIG. 2, the movable portion 3 ′ of the movable fixture is positioned in the hole 9 and held in its shape while being pushed to the maximum. By adjusting the distance between the hole 9 and the hole 10, the length of the drawn-out state, that is, the degree of deformation of the protective sheath 2 formed in a spiral shape can be determined. In order to realize a plurality of deformation degrees, there may be three or more holes. The holes and protrusions (projections) may be provided on the front surface of the fixture as shown in FIGS. 5 to 6, or may be provided on the side surfaces as shown in FIGS. The convex portion (projection) may be provided in a hole so as to be freely inserted into and removed from the hole, and may be pushed into the back when sliding, and may be pushed out by the action of a spring or the like when reaching the hole to be fitted into the hole. The positioning of the movable fixture in the pulled-out state is not limited to the hole and the convex portion (projection), and other positioning means can be used.

図５は図１のＡ−Ａ’断面図である。図５において、可動固定具の可動部３’は固定部３の穴１０に凸部１１が入り込んで位置決めされている。   FIG. 5 is a cross-sectional view taken along the line A-A ′ of FIG. 1. In FIG. 5, the movable portion 3 ′ of the movable fixture is positioned with the convex portion 11 entering the hole 10 of the fixed portion 3.

図６は可動固定具固定部３及び可動部３’の平面図である。図７は図６のＢ−Ｂ’断面図である。可動固定具の可動部３’が強引に引き出されると穴１０から凸部１１が外れて、必要以上に引き出されるため、それを防止する止め具８が設けてある。止め具８は可動固定具の固定部３に可動固定具の可動部３’を凸部１１が穴１０に入るまで挿入後、可動固定具の固定部３に差し込んで固定する。   FIG. 6 is a plan view of the movable fixture fixing part 3 and the movable part 3 '. FIG. 7 is a cross-sectional view taken along the line B-B ′ of FIG. 6. When the movable part 3 ′ of the movable fixing tool is forcibly pulled out, the convex part 11 is detached from the hole 10 and is pulled out more than necessary, and therefore a stopper 8 is provided to prevent this. The stopper 8 is inserted into the fixed part 3 of the movable fixture after being inserted into the fixed part 3 of the movable fixture until the convex part 11 enters the hole 10.

なお、図７では可動部３’が固定部３に覆われ、可動部３’を引き出す構造となっているが、可動部３’と固定部３をスライドさせることができれば、このような構造には限定されない。   In FIG. 7, the movable portion 3 ′ is covered with the fixed portion 3 and the movable portion 3 ′ is pulled out. However, if the movable portion 3 ′ and the fixed portion 3 can be slid, such a structure is obtained. Is not limited.

本発明の構成とすることでメーカーでの組立時、病院等での手術時は図１のように渦巻き状円形を真円状にして形状を固定し、ガイドワイヤー１の挿入抵抗を小さくできる。輸送、保管時は図２のように保護鞘を楕円状にして形状を固定し、コンパクトにすることが出来る。   By adopting the configuration of the present invention, when assembling at a manufacturer or during surgery at a hospital or the like, the spiral shape can be made into a perfect circle as shown in FIG. 1 to fix the shape, and the insertion resistance of the guide wire 1 can be reduced. At the time of transportation and storage, the protective sheath can be elliptical as shown in FIG.

なお、可動固定具３及び３’は公知の素材、例えば合成樹脂、金属、木材等で作製することができるが、作製の容易さからは合成樹脂製が好ましい。また、手術室内に持ち込まれることを考慮して、抗菌処理等を施しても良い。   The movable fixtures 3 and 3 'can be made of a known material such as synthetic resin, metal, wood, etc., but synthetic resin is preferable from the viewpoint of ease of production. In consideration of being brought into the operating room, antibacterial treatment or the like may be performed.

ストッパー５は保護鞘２に差し込まれ、ガイドワイヤー端部を止める働きと、ガイドワイヤーを生理的食塩水で洗浄するときにシリンジと連結出来る構造になっている。カニューレ６は先端がループになっているガイドワイヤー１の先端をカニューレの中に入れることで先端をほぼ直線にしてガイドワイヤーを挿入しやすくするためのガイドとなる。   The stopper 5 is inserted into the protective sheath 2 so as to stop the end portion of the guide wire and to be connected to the syringe when the guide wire is washed with physiological saline. The cannula 6 serves as a guide for making it easy to insert the guide wire by making the tip substantially straight by inserting the tip of the guide wire 1 whose tip is looped into the cannula.

［実施例１］
実施例で作製したガイドワイヤーホルダーを図１、図２、図５、図６及び図７に示す。ガイドワイヤー１は外径０．６５ｍｍの円形で、全長が２３００ｍｍ、先端ループ外径が４２ｍｍ、材質はＳＵＳ３０４ＷＰＢ（ＪＩＳ Ｇ ４３１４）で手元側端末は球面加工したものを使用した。保護鞘２は内径３ｍｍ、外径４ｍｍの高密度ポリエチレン（日本ポリオレフィン（株）ＫＢ１５１Ａ）の円形チューブで全長が１８７０ｍｍのものを使用した。ガイドワイヤー先端側に取り付けるカニューレ６は太い方の外径５．５ｍｍ、内径４．１ｍｍ、細い方の外径１．６ｍｍ、内径１．１ｍｍ、全長 ２５０ｍｍのポリプロピレン製を使用した。保護鞘２を固定する固定具４は保護鞘２を３列固定できるポリプロピレン製のものを使用した。保護鞘２の形状を変更してその形状を保持する伸縮出来る可動固定具３、及び３’はポリプロピレン製を使用した。ガイドワイヤー１を保護鞘２に挿入していったときのガイドワイヤー１を末端で止めるためのストッパー５はポリカーボネイト製のものを使用した。止め具８はポリプロピレン製を使用した。保護鞘２にガイドワイヤー１を挿入するときの挿入抵抗の改善効果を説明する。 [Example 1]
The guide wire holder produced in the Example is shown in FIG. 1, FIG. 2, FIG. 5, FIG. The guide wire 1 has a circular shape with an outer diameter of 0.65 mm, a total length of 2300 mm, an outer diameter of the tip loop of 42 mm, a material of SUS304WPB (JIS G 4314), and a hand-side terminal having a spherical shape. As the protective sheath 2, a circular tube of high-density polyethylene (Japan Polyolefin Co., Ltd. KB151A) having an inner diameter of 3 mm and an outer diameter of 4 mm and having a total length of 1870 mm was used. The cannula 6 attached to the distal end side of the guide wire was made of polypropylene having a thick outer diameter of 5.5 mm, an inner diameter of 4.1 mm, a thinner outer diameter of 1.6 mm, an inner diameter of 1.1 mm, and a total length of 250 mm. The fixture 4 for fixing the protective sheath 2 was made of polypropylene that can fix the protective sheath 2 in three rows. The movable movable fixtures 3 and 3 ′ that change the shape of the protective sheath 2 and maintain the shape can be made of polypropylene. The stopper 5 for stopping the guide wire 1 at the end when the guide wire 1 was inserted into the protective sheath 2 was made of polycarbonate. The stopper 8 was made of polypropylene. The effect of improving the insertion resistance when the guide wire 1 is inserted into the protective sheath 2 will be described.

図１において保護鞘２の渦巻き状円形の外径を２４ｃｍにした時の最大挿入抵抗は１４０ＣＮであった。挿入抵抗の測定はＯＨＢＡ ＳＩＫＩ製プッシュプルゲージ（バネばかり）で３００ＣＮ測定用、最小目盛りが５ＣＮのものを使用してプッシュ側にガイドワイヤー１をテープで固定して行った。図２において長円の短径を１５ｃｍ、長径を３０ｃｍにしたときの最大挿入抵抗は３００ＣＮであった。一般に、挿入抵抗が２８０ＣＮ以上になると挿入しづらくなる。   In FIG. 1, the maximum insertion resistance was 140 CN when the outer diameter of the spiral circular shape of the protective sheath 2 was 24 cm. The insertion resistance was measured by measuring 300 CN with an OHBA SIKI push-pull gauge (spring only) and having a minimum scale of 5 CN, and fixing the guide wire 1 to the push side with tape. In FIG. 2, the maximum insertion resistance when the minor axis of the ellipse was 15 cm and the major axis was 30 cm was 300 CN. Generally, it becomes difficult to insert when the insertion resistance is 280 CN or more.

次に梱包時の嵩の改善効果について説明する。図１のまま滅菌袋に入れた後、製品箱（厚紙製）に入れたとき平面積は２８ｃｍ×３５ｃｍで９８０ｃｍ2となった。図２のまま滅菌袋に入れた後、製品箱（厚紙製）に入れたとき平面積は１９ｃｍ×４１ｃｍで７７９ｃｍ2となり、平面積で２０％改善される。いずれも製品箱の高さは１．４ｃｍであるので、体積でも２０％改善される。 Next, the effect of improving the bulk at the time of packing will be described. When placed in a sterilized bag as in FIG. 1 and then in a product box (made of cardboard), the flat area was 980 cm 2 at 28 cm × 35 cm. When put in a sterilization bag as shown in FIG. 2 and then put in a product box (made of cardboard), the plane area becomes 779 cm 2 at 19 cm × 41 cm, which is improved by 20%. In both cases, the height of the product box is 1.4 cm, so the volume is improved by 20%.
