Description

カテーテル保持具Catheter holder
　本発明は、カテーテル保持具に関する。 The present invention relates to a catheter holder.
　カテーテル等の長尺状の医療器具は、搬送時や使用前の準備段階では、取り扱いを容易にし、その保護を図るために、所定の容器内に収容される。また、カテーテルは、例えば、下記特許文献１に記載されているようなホルダーチューブや、ホルダーチューブに取り付け可能なカテーテル保持具を利用して所定の形態（巻回状態）で保管や運搬がなされる。 A long medical device such as a catheter is accommodated in a predetermined container in order to facilitate handling and to protect the device at the time of transportation or at the preparation stage before use. In addition, the catheter is stored and transported in a predetermined form (rolled state) by using, for example, a holder tube as described in Patent Document 1 below and a catheter holder attachable to the holder tube. .
国際公開第２０１１／０３３９３９号International Publication No. 2011033939
　カテーテルには、長尺かつ可撓性を備える管状部（シャフトやシース等）と、コネクタやハブのように比較的硬度が高い部分（被保持部）とを備えるものが存在する。そのようなカテーテルの一例として、例えば、ＩＶＵＳカテーテル等の画像診断用カテーテルが存在する。 Some catheters include a long and flexible tubular portion (such as a shaft or a sheath) and a relatively hard portion such as a connector or a hub (a portion to be held). As an example of such a catheter, for example, there is an imaging diagnostic catheter such as an IVUS catheter.
　医師等の術者は、狭窄部等の病変部の治療や拡張に際し、画像診断用カテーテルを使用して病変部の観察を行う。術者は、病変部の観察を行った後、画像診断用カテーテルを生体管腔から一旦抜去し、バルーンカテーテルを使用して病変部を拡張させる処置を行う。術者は、病変部を拡張させた後、病変部の状態を確認するために、画像診断用カテーテルを生体管腔に再度挿入する。また、術者は、拡張後の病変部の状態によっては、画像診断用カテーテルを生体管腔から抜去した後、バルーンカテーテルにより狭窄部を再度拡張する処置（ポスト拡張）を行うことがある。 An operator such as a doctor observes a lesioned part using an imaging diagnostic catheter when treating or dilating a lesioned part such as a narrowed part. After observing the lesion area, the operator temporarily removes the diagnostic imaging catheter from the living body lumen and performs a treatment to dilate the lesion area using a balloon catheter. After expanding the lesion, the operator reinserts the diagnostic imaging catheter into the living body lumen in order to confirm the condition of the lesion. In addition, the operator may perform a treatment (post-expansion) in which the narrowed portion is re-expanded with a balloon catheter after removing the diagnostic imaging catheter from the living body lumen, depending on the state of the lesion after expansion.
　画像診断用カテーテルは、上記のような手順で手技が行われている最中、ＭＤＵ等の外部駆動装置との連結を維持する。また、画像診断用カテーテルは、その使用が中断されている間（例えば、バルーンカテーテル等による処置が行われている間）、製品運搬時等に使用されたホルダーチューブを利用して一時的に保管される。この際、ホルダーチューブと外部駆動装置との間にカテーテル保持具が配置されていると、ホルダーチューブへ画像診断用カテーテルを出し入れする際や生体管腔へ画像診断用カテーテルを再度挿入する際に、カテーテル保持具が邪魔になり、画像診断用カテーテルを使用した円滑な手技が妨げられる可能性がある。 The diagnostic imaging catheter maintains the connection with the external drive device such as the MDU while the procedure is performed in the above-described procedure. In addition, while the use of the diagnostic imaging catheter is suspended (for example, while a treatment with a balloon catheter or the like is being performed), it is temporarily stored using a holder tube used at the time of product transportation or the like. Be done. At this time, when the catheter holder is disposed between the holder tube and the external driving device, when the diagnostic imaging catheter is inserted into or removed from the holder tube, or when the diagnostic imaging catheter is reinserted into the living body lumen, The catheter holder may get in the way and prevent smooth procedures using the imaging diagnostic catheter.
　本発明は上記課題に鑑みてなされたものであり、カテーテルを使用した手技の円滑な進行が妨げられることを防止できるカテーテル保持具を提供することを目的とする。 The present invention has been made in view of the above problems, and it is an object of the present invention to provide a catheter holder that can prevent smooth progress of a procedure using a catheter.
　上記目的を達成する一態様としてのカテーテル保持具は、管状部および前記管状部よりも硬質な被保持部を備えるカテーテルを保持するためのカテーテル保持具であって、前記管状部を収納可能なホルダー部材に取り付けられる取り付け部と、前記被保持部を保持する保持部と、前記取り付け部に対する前記保持部側の位置を変更可能にする可変部と、を有する。 A catheter holder according to one aspect of the present invention for achieving the above object is a catheter holder for holding a catheter including a tubular portion and a held portion harder than the tubular portion, the holder being capable of housing the tubular portion.

Further, the number of supporting portions is not limited to three, and can be appropriately increased or decreased, and the positions of the supporting portions can be appropriately changed.
　図１および図２（Ａ）に示すように、カテーテル保持部材１００の保持部１２０は、カテーテル５００の被保持部（基端ハブ）５３０を保持可能な溝部１２１ａが形成された第１保持部１２１と、カテーテル５００の被保持部（ユニットコネクタ）５２０を保持可能な溝部１２２ａが形成された第２保持部１２２と、第１保持部１２１と第２保持部１２２を一体的に接続する延在部１２４と、延在部１２４と取り付け部１１０を接続する基部１２５と、を有している。 As shown in FIGS. 1 and 2A, the holding portion 120 of the catheter holding member 100 is a first holding portion 121 in which a groove portion 121a capable of holding the held portion (proximal hub) 530 of the catheter 500 is formed. , And a second holding portion 122 in which a groove portion 122a capable of holding the held portion (unit connector) 520 of the catheter 500 is formed, and an extension portion integrally connecting the first holding portion 121 and the second holding portion 122 And a base portion 125 connecting the extension portion 124 and the attachment portion 110.
　第１保持部１２１の溝部１２１ａは、カテーテル５００の被保持部５３０を着脱可能に固定するスナップフィット機構を備える。同様に、第２保持部１２２の溝部１２２ａは、カテーテル５００の被保持部５２０を着脱可能に固定するスナップフィット機構を備える。 The groove portion 121 a of the first holding portion 121 includes a snap fit mechanism for detachably fixing the held portion 530 of the catheter 500. Similarly, the groove portion 122a of the second holding portion 122 includes a snap fit mechanism for detachably fixing the held portion 520 of the catheter 500.
　第１保持部１２１の溝部１２１ａの中心軸ｃ１と第２保持部１２２の溝部１２２ａの中心軸ｃ２は、同軸上に配置している。そのため、図１に示すように、カテーテル５００の被保持部５３０とカテーテル５００の被保持部５２０は、カテーテル保持部材１００によりカテーテル５００が保持される際、各溝部１２１ａ、１２２ａの軸線に沿って略直線状に配置される。また、カテーテル５００の被保持部５２０から先端側（生体管腔挿入時のの遠位側）に延在するカテーテル５００の管状部５１０の一部は、ホルダー部材３００のポート部３２０側に向けて略直線状に配置される。 The central axis c1 of the groove portion 121a of the first holding portion 121 and the central axis c2 of the groove portion 122a of the second holding portion 122 are coaxially arranged. Therefore, as shown in FIG. 1, when the catheter 500 is held by the catheter holding member 100, the held portion 530 of the catheter 500 and the held portion 520 of the catheter 500 substantially follow the axis of the grooves 121 a and 122 a. Arranged in a straight line. In addition, a part of the tubular portion 510 of the catheter 500 extending from the held portion 520 of the catheter 500 to the tip side (the distal side at the time of insertion of a living lumen) toward the port 320 of the holder member 300 It is arranged in a substantially straight line.
　カテーテル保持部材１００を構成する取り付け部１１０および保持部１２０は、例えば、ＡＢＳ樹脂、ポリエチレンテレフタレート、ポリメチルメタクリレート、ポリカーボネート等の硬質の樹脂材料、ガラス、セラミックスなどで形成できる。 The attachment portion 110 and the holding portion 120 constituting the catheter holding member 100 can be formed of, for example, a hard resin material such as ABS resin, polyethylene terephthalate, polymethyl methacrylate, polycarbonate, glass, ceramics or the like.
　図２（Ａ）および図２（Ｂ）に示すように、可変部１３０は、取り付け部１１０に対して保持部１２０を分離可能に連結する連結部１４０を有している。 As shown in FIGS. 2A and 2B, the variable part 130 has a connecting part 140 that connects the holding part 120 to the mounting part 110 in a detachable manner.
　連結部１４０は、取り付け部１１０の基部１１５の端部（保持部１２０側に位置する端部）に形成された突起部１４１と、保持部１２０の基部１２５の端部（取り付け部１１０側に位置する端部）に形成された溝部１４２と、を有している。 The connecting portion 140 is a protrusion 141 formed on an end of the base 115 of the mounting portion 110 (an end located on the holding portion 120) and an end of the base 125 of the holding portion 120 (on the mounting portion 110). And the groove portion 142 formed in the
　図２（Ａ）に示すように、連結部１４０の突起部１４１は、連結部１４０の溝部１４２と嵌合可能に構成している。突起部１４１が溝部１４２に嵌合することにより、取り付け部１１０の基部１１５と保持部１２０の基部１２５とが連結される。また、図２（Ｂ）に示すように、連結部１４０の突起部１４１は、連結部１４０の溝部１４２と分離可能（嵌合の解除が可能）である。突起部１４１が溝部１４２から分離することにより、取り付け部１１０の基部１１５と保持部１２０の基部１２５との連結が解除される。また、取り付け部１１０と保持部１２０は、突起部１４１および溝部１４２による連結と分離を繰り返し行うことが可能である。 As shown in FIG. 2A, the projection 141 of the connecting portion 140 is configured to be able to be fitted with the groove 142 of the connecting portion 140. By fitting the protrusion 141 into the groove 142, the base 115 of the mounting portion 110 and the base 125 of the holding portion 120 are connected. Further, as shown in FIG. 2B, the protrusion 141 of the connecting portion 140 is separable from the groove 142 of the connecting portion 140 (the fitting can be released). When the protrusion 141 is separated from the groove 142, the connection between the base 115 of the attachment 110 and the base 125 of the holder 120 is released. Further, the attachment portion 110 and the holding portion 120 can be repeatedly connected and separated by the protrusion portion 141 and the groove portion 142.
　なお、連結部１４０は、取り付け部１１０と保持部１２０を分離可能に構成されている限り、構造や形態等は特に限定されない。例えば、突起部１４１や溝部１４２の位置や個数を変更することが可能である。また、例えば、取り付け部１１０側に溝部１４２を形成し、保持部１２０側に突起部１４１を形成した構造、薄肉部（破断部）、異種の材質同士の接合、接着剤による接合等で形成されており、一度分離すると再度連結ができなくなる構造等を採用することも可能である。 In addition, as long as the connection part 140 is comprised so that attachment part 110 and the holding part 120 can be isolate | separated, a structure, a form, etc. are not specifically limited. For example, the positions and the number of the protrusions 141 and the grooves 142 can be changed. Further, for example, the groove 142 is formed on the side of the mounting portion 110, and the protrusion 141 is formed on the side of the holding portion 120. The thin portion (broken portion), bonding different materials, bonding with adhesive It is also possible to adopt a structure that can not be rejoined once separated.
　カテーテル保持具１０が備える連結部１４０は、次のような利点を有している。 The connection portion 140 provided in the catheter holder 10 has the following advantages.
　例えば、医師等の術者は、カテーテル（画像診断用カテーテル）５００を使用した手技において、カテーテル５００を生体管腔から一旦抜去した後、カテーテル５００の管状部５１０をホルダー部材３００に収納して一時的に保管することがある。カテーテル５００は、病変部等に対する処置（例えば、ポスト拡張）を終えた後、病変部の様子を再度観察する際にも使用されるため、ホルダー部材３００を使用して管状部５１０が一時的に保管されている間も、その基端部側（基端ハブ５３０側）はＭＤＵ等の外部駆動装置と連結された状態に維持される。また、上記のように手技が進められている間、カテーテル５００の管状部５１０を巻き回した状態に維持するために、カテーテル保持具１０の各支持部１１１、１１２、１１３には、管状部５１０が挿入された巻き回した状態のホルダー部材３００が取り付けられる。手技を行っている最中、ホルダー部材３００と外部駆動装置との間にカテーテル保持部材１００の保持部１２０が配置されると、ホルダー部材３００へ管状部５１０を出し入れする際や、生体管腔へカテーテル５００を再度挿入する際に、保持部１２０が邪魔になり、手技の円滑な進行が妨げられる可能性がある。 For example, in a procedure using a catheter (catheter for diagnostic imaging) 500, an operator such as a doctor temporarily removes the catheter 500 from the living body lumen, stores the tubular portion 510 of the catheter 500 in the holder member 300, and temporarily May be stored. Since the catheter 500 is also used when observing the appearance of the lesion again after the treatment (for example, post dilation) for the lesion or the like, the tubular portion 510 is temporarily used by using the holder member 300. While being stored, the proximal end side (proximal hub 530 side) is maintained in a state of being connected to an external drive such as an MDU. In addition, in order to maintain the tubular portion 510 of the catheter 500 in a wound state while the procedure is advanced as described above, each supporting portion 111, 112, 113 of the catheter holder 10 has a tubular portion 510. The holder member 300 in a wound state is inserted. When the holding portion 120 of the catheter holding member 100 is disposed between the holder member 300 and the external drive device during the procedure, the tubular portion 510 can be inserted into or removed from the holder member 300, or into the living body lumen. When the catheter 500 is reinserted, the holding portion 120 may get in the way, preventing smooth progress of the procedure.
　上記のような課題に対して、術者は、図２（Ｂ）に示すように、保持部１２０と取り付け部１１０との連結を解除し、保持部１２０を所定の場所に退避させることにより、保持部１２０による手技の円滑な進行が妨げられることを防止できる。 To solve the above-mentioned problems, the operator releases the connection between the holding unit 120 and the attaching unit 110 as shown in FIG. 2B, and retracts the holding unit 120 to a predetermined place.

In addition, in the catheter which does not need an accessory, use of the accessory holding member 200 may be abbreviate | omitted.
　また、付属品保持部材２００は、スナップフィット機構を備える溝部により、各付属品６１０、６２０、６３０を保持および固定することができる。このため、医師等の術者は、付属品保持部材２００から各付属品６１０、６２０、６３０を取り外す際、その作業を容易かつ円滑に行うことができる。 Also, the accessory holding member 200 can hold and fix the respective accessories 610, 620, 630 by means of grooves provided with a snap fit mechanism. Therefore, an operator such as a doctor can perform the work easily and smoothly when removing each of the accessories 610, 620, 630 from the accessory holding member 200.
　カテーテル保持部材１００は、第１保持部１２１および第２保持部１２２によるカテーテル５００への固定を容易に解除できる構造（各保持部１２１、１２２の着脱が容易な構造）であることが好ましい。同様に、付属品保持部材２００は、各支持部２１１、２１２、２１３、２１４によるホルダー部材３００への固定を容易に解除できる構造（各支持部２１１、２１２、２１３、２１４の着脱が容易な構造）であることが好ましい。上記の固定を容易に解除できる構造としては、例えば、手指等により押すと、固定した部分（溝部やその周辺部）が広がって外れやすくなる構造を採用できる。例えば、後述する各変形例についても、着脱を容易にする構造として上記と同様の構造を採用することが可能である。 The catheter holding member 100 preferably has a structure (a structure in which the holding portions 121 and 122 can be easily attached and detached) by which the fixation to the catheter 500 by the first holding portion 121 and the second holding portion 122 can be easily released. Similarly, the accessory holding member 200 can easily release the fixing to the holder member 300 by the supports 211, 212, 213, and 214 (structures for facilitating the attachment and detachment of the supports 211, 212, 213, and 214). Is preferred. As a structure capable of easily releasing the above-mentioned fixation, for example, a structure in which a fixed portion (the groove portion or the periphery thereof) spreads out easily when pressed by a finger or the like can be adopted. For example, it is possible to adopt the same structure as the above as the structure for facilitating the attachment / detachment also to each of the modifications described later.
　付属品保持部材２００は、固定が容易に解除可能に構成される場合、次のような利点を有する。例えば、手術室においてカテーテル５００を使用した手技の準備をする際、準備作業を行う人員が多い時と少ない時とでは、準備の仕方が異なる。準備作業を行う人員が多い時には、カテーテル台とは別の作業台でプライミングの準備作業を行う。そのため、プライミングに使用する各付属品６１０、６２０、６３０は別の作業台へカテーテル５００と一緒に運ぶことが好ましい。また、準備作業を行う人員が少ない時には、カテーテル台でカテーテル５００のプライミングの準備をするため、カテーテル５００は収容袋４００から取り出された状態のまま、各付属品６１０、６２０、６３０を使用してプライミングが行われる。上記のように、カテーテル５００の準備作業の手順は、手術室内に居る作業者の人数等により異なる。そのため、手術の準備を行う作業者は、手術室に居る作業者の数や準備作業の進行状況等に応じて、カテーテル保持部材１００に付属品保持部材２００を適宜着脱させることにより、準備作業をより一層円滑に進めることが可能になる。 The accessory holding member 200 has the following advantages when it is configured to be easily releasable. For example, when preparing a procedure using the catheter 500 in the operating room, the method of preparation differs depending on whether the number of people performing the preparation operation is large or small. When there are a large number of people performing preparation work, the priming preparation work is performed on a worktable different from the catheter table. As such, each accessory 610, 620, 630 used for priming is preferably carried along with the catheter 500 to a separate workbench. In addition, when the preparation work is performed by a small number of people, in order to prepare for priming of the catheter 500 in the catheter table, the catheters 500 are removed from the storage bag 400 and using the respective accessories 610, 620, 630 Priming takes place. As described above, the procedure of the preparation operation of the catheter 500 differs depending on the number of workers present in the operating room. Therefore, the worker who prepares for the operation appropriately performs the preparation work by attaching and detaching the accessory holding member 200 to the catheter holding member 100 according to the number of the workers in the operating room, the progress of the preparation work, and the like. It will be possible to proceed more smoothly.
　次に、本実施形態に係るカテーテル保持具１０の作用効果を説明する。 Next, the operation and effect of the catheter holder 10 according to the present embodiment will be described.

Therefore, an operator such as a doctor can evacuate the holding unit 120 to a desired position by a simple operation of separating the holding unit 120. Moreover, since the variable part 130 is comprised by a comparatively simple structure, reduction of the manufacturing cost of the catheter holding tool 10 can be aimed at.
　また、カテーテル保持具１０は、ホルダー部材３００に着脱可能に構成された付属品保持部材２００を有している。付属品保持部材２００は、巻回された状態のホルダー部材３００の内周側（図１に示す巻回の中心Ｏ側）において、カテーテル５００に付属する各付属品６１０、６２０、６３０を保持する。 In addition, the catheter holder 10 has an accessory holding member 200 configured to be attachable to and detachable from the holder member 300. The accessory holding member 200 holds the respective accessories 610, 620, 630 attached to the catheter 500 on the inner peripheral side (the center O side of the winding shown in FIG. 1) of the holder member 300 in the wound state. .
　上記のように構成したカテーテル保持具１０によれば、製造作業者等は、製品出荷時等に各付属品６１０、６２０、６３０が梱包されている否かを容易に確認することができる。また、ホルダー部材３００の内周側の余剰なスペースにおいて各付属品６１０、６２０、６３０が保持されるため、製品をコンパクトに収納することができ、製品の占有面積が増加するのを抑制できる。 According to the catheter holder 10 configured as described above, a manufacturer or the like can easily confirm whether or not each accessory 610, 620, 630 is packed at the time of product shipment or the like. Further, since the respective accessories 610, 620, 630 are held in the surplus space on the inner peripheral side of the holder member 300, the product can be compactly stored, and an increase in the occupied area of the product can be suppressed.
　次に、カテーテル保持具１０が備えるカテーテル保持部材１００の各変形例を説明する。各変形例の説明においては、上述した実施形態において既に説明した部材等についての説明を適宜省略する。 Next, each modification of the catheter holding member 100 provided in the catheter holding tool 10 will be described.

　図６には、変形例３に係るカテーテル保持部材１００Ｃを示す。 FIG. 6 shows a catheter holding member 100C according to the third modification.
　変形例３に係るカテーテル保持部材１００Ｃは、取り付け部１１０の第１支持部１１１と取り付け部１１０の第２支持部１１２の向きが前述した実施形態と異なる。具体的には、第１支持部１１１に形成された各溝部１１１ａ、１１１ｂと、第２支持部１１２に形成された各溝部１１２ａ、１１２ｂは、ホルダー部材３００に対する嵌め込み方向が対向するように配置されている。 The catheter holding member 100C according to the third modification differs from the embodiment described above in the orientation of the first support portion 111 of the attachment portion 110 and the second support portion 112 of the attachment portion 110. Specifically, the grooves 111a and 111b formed in the first support 111 and the grooves 112a and 112b formed in the second support 112 are arranged such that the fitting directions with respect to the holder 300 are opposite to each other. ing.
　図６に示すように、第１支持部１１１の各溝部１１１ａ、１１１ｂは、ホルダー部材３００の管状部３１０を上側から挿入することで取り付けがなされる。一方、第２支持部１１２の各溝部１１２ａ、１１２ｂは、ホルダー部材３００の管状部３１０を下側から挿入することで取り付けがなされる。このため、ホルダー部材３００の管状部３１０は、一方の側（例えば、上側または下側）からカテーテル保持部材１００Ｃに対して近付けられる場合、第１支持部１１１の各溝部１１１ａ、１１１ｂには嵌合せず、第２支持部１１２の各溝部１１２ａ、１１２ｂにも嵌合しない。また、第３支持部１１３の各溝部１１３ａ、１１３ｂは、第１支持部１１１の各溝部１１１ａ、１１１ｂと同方向を向くように形成されている。このため、ホルダー部材３００の管状部３１０は、第３支持部１１３の各溝部１１３ａ、１１３ｂにも嵌合しない。 As shown in FIG. 6, the respective groove portions 111 a and 111 b of the first support portion 111 are attached by inserting the tubular portion 310 of the holder member 300 from the upper side. On the other hand, the respective groove portions 112a and 112b of the second support portion 112 are attached by inserting the tubular portion 310 of the holder member 300 from the lower side. Therefore, when the tubular portion 310 of the holder member 300 is brought close to the catheter holding member 100C from one side (for example, the upper side or the lower side), the tubular portion 310 is fitted in the respective groove portions 111a and 111b of the first support portion 111. Also, the grooves 112a and 112b of the second support 112 are not fitted. The groove portions 113a and 113b of the third support portion 113 are formed to face in the same direction as the groove portions 111a and 111b of the first support portion 111. For this reason, the tubular portion 310 of the holder member 300 does not fit in the groove portions 113 a and 113 b of the third support portion 113.
　図６に示すように、本変形例に係るカテーテル保持部材１００Ｃには、保持部１２０の基部１２５から延長する延長部１２６と、延長部１２６の端部に形成された第４支持部１１４が備えられている。 As shown in FIG. 6, the catheter holding member 100C according to the present modification includes an extension 126 extending from the base 125 of the holding unit 120 and a fourth support 114 formed at the end of the extension 126. It is done.
　第４支持部１１４には、ホルダー部材３００の管状部３１０に着脱可能な複数の溝部１１４ａ、１１４ｂが形成されている。例えば、カテーテル保持部材１００Ｃをホルダー部材３００の管状部３１０に取り付ける場合、第４支持部１１４のみを介して、ホルダー部材３００の管状部３１０にカテーテル保持部材１００Ｃを固定することができる。このように、一つの支持部１１４のみを介してホルダー部材３００とカテーテル保持部材１００Ｃとの固定を行うことにより、第４支持部１１４の固定を解除する簡単な作業でホルダー部材３００からカテーテル保持部材１００Ｃ全体を取り外すことが可能になる。 The fourth support portion 114 is formed with a plurality of groove portions 114 a and 114 b attachable to and detachable from the tubular portion 310 of the holder member 300. For example, when the catheter holding member 100C is attached to the tubular portion 310 of the holder member 300, the catheter holding member 100C can be fixed to the tubular portion 310 of the holder member 300 only through the fourth support portion 114. Thus, by fixing the holder member 300 and the catheter holding member 100C only through the one supporting portion 114, the catheter holding member can be removed from the holder member 300 by a simple operation of releasing the fixation of the fourth supporting portion 114. It is possible to remove the entire 100C.
　次に、カテーテル保持具１０が備える付属品保持部材２００の各変形例を説明する。各変形例の説明においては、上述した実施形態において既に説明した部材等についての説明を適宜省略する。 Next, modifications of the accessory holding member 200 provided in the catheter holder 10 will be described.

And a second support portion 112 provided with 112c.
　第２支持部１１２は、図１に示すホルダー部材３００の管状部３１０の巻回の中心Ｏ側（図１２の矢印Ａで示す方向）およびホルダー部材３００の管状部３１０の巻回方向側に開口されている。 The second support portion 112 is opened at the center O side (direction shown by arrow A in FIG. 12) of the winding of the tubular portion 310 of the holder member 300 shown in FIG. 1 and the winding direction side of the tubular portion 310 of the holder member 300. It is done.
　取り付け部１１０Ｄは、図１２、図１３に示すように、第２支持部１１２を基準にして、ホルダー部材３００の管状部３１０の巻回方向において第１支持部１１１と反対側に配置された第３支持部１１３を有している。第３支持部１１３には、巻回された状態のホルダー部材３００の管状部３１０の一部が嵌合される溝部１１３ａ、１１３ｂが形成されている。 As shown in FIGS. 12 and 13, the mounting portion 110D is disposed on the opposite side of the first support portion 111 in the winding direction of the tubular portion 310 of the holder member 300 with reference to the second support portion 112. 3 has a support portion 113. The third support portion 113 is formed with groove portions 113a and 113b into which a part of the tubular portion 310 of the holder member 300 in a wound state is fitted.
　図１２、図１４に示すように、第２支持部１１２は、ホルダー部材３００の管状部３１０の巻回の中心Ｏ側へ突出する第１突出部１１２ａおよび第２突出部１１２ｂを有している。 As shown in FIGS. 12 and 14, the second support 112 has a first protrusion 112 a and a second protrusion 112 b that protrude toward the center O of the winding of the tubular portion 310 of the holder member 300. .
　第１突出部１１２ａは、第１支持部１１１の各溝部１１１ａ、１１１ｂが開口する一方の側（図１２、図１４に示す矢印ａの上方側）で巻回されたホルダー部材３００の管状部３１０の一部を覆うように配置されている。なお、図１４においてホルダー部材３００の管状部３１０の巻回された部分は符号３１１、３１２で例示している。 The first projecting portion 112a is a tubular portion 310 of the holder member 300 wound on one side (upper side of the arrow a shown in FIGS. 12 and 14) where the respective groove portions 111a and 111b of the first support portion 111 are opened. It is arranged to cover a part of the In FIG. 14, the wound portions of the tubular portion 310 of the holder member 300 are illustrated by reference numerals 311 and 312.
　図１４に示すように、第２突出部１１２ｂは、第１突出部１１１との間に保持空間１１２ｃを形成するように第１突出部１１２ａに対向して配置されている。 As shown in FIG. 14, the second protrusion 112 b is disposed to face the first protrusion 112 a so as to form a holding space 112 c between the second protrusion 112 b and the first protrusion 111.
　第１突出部１１２ａは、ホルダー部材３００の管状部３１０の巻回の中心Ｏ側へ向けて、基部１１５に対して略平行に延びている。このように第１突出部１１２ａが形成されているため、ホルダー部材３００の管状部３１０が各支持部１１１、１１３の溝部１１１ａ、１１１ｂ、１１３ａ、１１３ｂに嵌合された状態において、第１突出部１１２ａは、ホルダー部材３００の管状部３１０を上方側から押えることができ、各溝部１１１ａ、１１１ｂ、１１３ａ、１１３ｂに対してホルダー部材３００の管状部３１０をしっかりと固定することができる。 The first protrusion 112 a extends substantially parallel to the base 115 toward the center O of the winding of the tubular portion 310 of the holder member 300. Thus, since the first protrusion 112a is formed, the first protrusion is in a state in which the tubular portion 310 of the holder member 300 is fitted in the grooves 111a, 111b, 113a, 113b of the support portions 111, 113. The 112a can press the tubular portion 310 of the holder member 300 from the upper side, and can securely fix the tubular portion 310 of the holder member 300 to the grooves 111a, 111b, 113a, 113b.
　なお、第１突出部１１２ａの基部１１５に対する傾斜角度θ１は、例えば、１°以下に設定することができる。 In addition, inclination-angle (theta) 1 with respect to the base 115 of the 1st protrusion part 112a can be set to 1 degree or less, for example.
　第１突出部１１２ａの高さ位置（図１４の上下方向の位置）は、各支持部１１１、１１３の溝部１１１ａ、１１１ｂ、１１３ａ、１１３ｂにホルダー部材３００の管状部３１０を嵌合させた状態において、ホルダー部材３００の巻回された各部３１１、３１２が第１突出部１１２ａの上部側の内面と接触するように設定することが好ましい。また、第１突出部１１２ａの高さ位置は、ホルダー部材３１０の巻回された各部３１１、３１２が第２突出部１１２ｂとの間に隙間ｇを形成するように設定することが好ましい。 In the height position (the position in the vertical direction in FIG. 14) of the first protrusion 112 a, the tubular portion 310 of the holder member 300 is fitted in the grooves 111 a, 111 b, 113 a, 113 b of the support portions 111, 113. Preferably, the wound portions 311 and 312 of the holder member 300 are set in contact with the upper inner surface of the first protrusion 112a. Further, the height position of the first protrusion 112 a is preferably set so that the wound portions 311 and 312 of the holder member 310 form a gap g with the second protrusion 112 b.
　第１突出部１１２ａの高さ位置を上記のような隙間ｇが形成される位置に設定することにより、後述するようにホルダー部材３００の管状部３１０から取り付け部１１０Ｄを取り外す際（図１４を参照）、ホルダー部材３００の管状部３１０の各部３１１、３１２に対して取り付け部１１０Ｄを相対的に回動させることが可能になる。なお、隙間ｇの大きさや形成される位置は、取り付け部１１０Ｄを回動させることが可能であれば特に限定されない。そのため、隙間ｇは、ホルダー部材３００の管状部３１０の一部３１１と第２突出部１１２ｂとの間に少なくとも形成されていればよい。 When removing the attachment portion 110D from the tubular portion 310 of the holder member 300 as described later by setting the height position of the first protrusion 112a to a position where the gap g as described above is formed (see FIG. 14) And the mounting portion 110D can be rotated relative to the portions 311 and 312 of the tubular portion 310 of the holder member 300. The size of the gap g and the position to be formed are not particularly limited as long as the attachment portion 110D can be rotated. Therefore, the gap g may be at least formed between the portion 311 of the tubular portion 310 of the holder member 300 and the second protrusion 112 b.
　第２突出部１１２ｂは、第１突出部１１２ａよりもホルダー部材３００の管状部３１０の巻回の中心Ｏ側へ突出している。このように第２突出部１１２ｂが形成されているため、保持空間１１２ｃ内へホルダー部材３００の管状部３１０を挿入する作業を容易に行うことができる。また、ホルダー部材３００の管状部３１０において第２支持部１１２の保持空間１１２ｃに保持されていた部分３１１、３１２は、第１突出部１１２ａの上部側の内面によりガイドされながら、取り付け部１１０Ｄの上方側へ向けて移動することができる。したがって、第２支持部１１２の保持空間１１２ｃ内に保持されたホルダー部材３００の管状部３１０の各部３１１、３１２を保持空間１１２ｃから保持空間１１２ｃの外部へ容易に移動させることができる。 The second protrusion 112 b protrudes from the first protrusion 112 a toward the center O of the winding of the tubular portion 310 of the holder member 300. Since the second projecting portion 112 b is formed as described above, the work of inserting the tubular portion 310 of the holder member 300 into the holding space 112 c can be easily performed. Further, the portions 311 and 312 held in the holding space 112c of the second support portion 112 in the tubular portion 310 of the holder member 300 are guided by the upper inner surface of the first projecting portion 112a while the upper portion of the attachment portion 110D is It can move towards the side. Therefore, the portions 311 and 312 of the tubular portion 310 of the holder member 300 held in the holding space 112 c of the second support 112 can be easily moved from the holding space 112 c to the outside of the holding space 112 c.
　第２突出部１１２ｂは、ホルダー部材３００の管状部３１０の巻回の中心Ｏ側へ向けて第１突出部１１２ａから離間するように傾斜して延びている。このように第２突出部１１２ｂが形成されているため、ホルダー部材３１０の巻回された各部３１１、３１２が第２突出部１１２ｂとの間に隙間ｇを容易に形成することができる。なお、第２突出部１１２ｂの基部１１５に対する傾斜角度θ２は、例えば、０°より大きく３０°以下が好ましく、５°以上１５°以下がより好ましい。 The second protrusion 112 b extends obliquely toward the center O of the winding of the tubular portion 310 of the holder member 300 so as to be separated from the first protrusion 112 a. Since the second protrusion 112 b is formed as described above, the wound portions 311 and 312 of the holder member 310 can easily form the gap g with the second protrusion 112 b. The inclination angle θ2 of the second protrusion 112 b with respect to the base 115 is, for example, preferably greater than 0 ° and 30 ° or less, and more preferably 5 ° or more and 15 ° or less.
　術者等は、取り付け部１１０Ｄからホルダー部材３００の管状部３１０を取り外す際、図１４に示すように、基部１１５の任意の箇所を支点ｓ１にして、取り付け部１１０Ｄの先端側（ホルダー部材３００の管状部３１０の巻回の中心Ｏ側）を回動させることにより、各支持部１１１、１１３からホルダー部材３００の管状部３１０を取り外す。なお、第２支持部１１２は、例えば、図１４の各矢印で示すようにホルダー部材１１０Ｄの上方側へ向けて回動させる。 When removing the tubular portion 310 of the holder member 300 from the attachment portion 110D, the operator or the like takes an arbitrary portion of the base 115 as a fulcrum as shown in FIG. The tubular portion 310 of the holder member 300 is removed from each of the support portions 111 and 113 by rotating the center O side of the winding of the tubular portion 310. The second support portion 112 is rotated toward the upper side of the holder member 110D, for example, as indicated by arrows in FIG.
　術者等が上記の作業を行うと、ホルダー部材３００の管状部３１０において各支持部１１１、１１３の溝部１１１ａ、１１１ｂ、１１３ａ、１１３ｂに嵌合されていた部分は、各溝部１１１ａ、１１１ｂ、１１３ａ、１１３ｂから抜け出る方向（図１２、図１３の矢印ａ方向、図１４の上方）へ向けて移動する。一方、ホルダー部材３００の管状部３１０において第２支持部１１２の保持空間１１２ｃに保持されていた部分３１１、３１２は、第１突出部１１２ａの上部側の内面によりガイドされながら、保持空間１１２ｃから保持空間１１２ｃの外部へ移動し、溝部１１１ａ、１１１ｂ、１１３ａ、１１３ｂに嵌合されていたホルダー部材３００の管状部３１０と同様に、取り付け部１１０Ｄの上方側へ向けて移動する。そのため、術者等は、取り付け部１１０Ｄの先端側（ホルダー部材３００の管状部３１０の巻回の中心Ｏ側）を回動させることにより、ホルダー部材３００の管状部３１０を各支持部１１１、１１３の溝部１１１ａ、１１１ｂ、１１３ａ、１１３ｂから容易に取り外すことができる。 When the operator or the like performs the above operation, the portions of the tubular portion 310 of the holder member 300 fitted in the grooves 111a, 111b, 113a, 113b of the support portions 111, 113 are the grooves 111a, 111b, 113a. , 113b (direction of arrow a in FIG. 12, FIG. 13; upward in FIG. 14). On the other hand, the portions 311 and 312 held in the holding space 112c of the second support portion 112 in the tubular portion 310 of the holder member 300 are held from the holding space 112c while being guided by the upper inner surface of the first projecting portion 112a. It moves to the outside of the space 112c, and moves upward of the mounting portion 110D, similarly to the tubular portion 310 of the holder member 300 fitted in the groove portions 111a, 111b, 113a, 113b. Therefore, the surgeon or the like rotates the distal end side (the center O side of the winding of the tubular portion 310 of the holder member 300) of the attachment portion 110D to support the tubular portion 310 of the holder member 300 with the respective support portions 111 and 113. Can be easily removed from the grooves 111a, 111b, 113a, 113b.
　術者等は、ホルダー部材３００の管状部３１０からカテーテル５００の管状部５１０を一旦取り出した後、カテーテル５００の管状部５１０をホルダー部材３００の管状部３１０へ再度挿入する際、カテーテル保持具が作業の妨げになるような場合には、上述した作業手順にしたがって取り付け部１１０Ｄをホルダー部材３００の管状部３１０から取り外す。術者等は、取り付け部１１０Ｄをホルダー部材３００の管状部３１０から容易に取り外すことができるため、カテーテル５００の管状部５１０をホルダー部材３００の管状部３１０へ再度挿入する作業を円滑に行うことが可能になる。 The operator once removes the tubular portion 510 of the catheter 500 from the tubular portion 310 of the holder member 300, and then reinserts the tubular portion 510 of the catheter 500 into the tubular portion 310 of the holder member 300. In such a case, the mounting portion 110D is removed from the tubular portion 310 of the holder member 300 in accordance with the above-described operation procedure. Since the operator etc. can easily remove the mounting portion 110D from the tubular portion 310 of the holder member 300, it is possible to smoothly insert the tubular portion 510 of the catheter 500 into the tubular portion 310 of the holder member 300 again. It will be possible.
