Description

盘管 技术领域
本实用新型属于医疗器械技术领域,具体涉及一种盘管。
背景技术
动脉瘤是临床上常见的血管疾病,多发生在老年人身上,这种疾病容易导致主动脉瘤破裂,对患者的生命造成极大的威胁。
随着现在医学技术的不断发展,利用微创手术将覆膜支架植入体内,治疗主动脉瘤及夹层动脉瘤的治疗手术被使用,因其创伤小,恢复快,得到了广泛应用。此治疗方式是将覆膜支架压缩入输送装置中,沿着事先植入的导丝轨道引导进入人体,到达病变位置后,将覆膜支架释放出来以隔绝血流和病变位置,同时重建血流通道,动脉瘤和夹层在丧失血流供应后,瘤腔内残存血液逐渐形成血栓并肌化成血管组织,扩张状态的瘤壁因受压而收缩,逐渐恢复原始状态,从而达到治疗动脉瘤和夹层的目的。
然而,人体的血管结构复杂,当病变发生在分支部位的话,就需要采用能重建分支动脉的覆膜支架。目前针对此类病变的覆膜支架有一种是内置覆膜支架,即直管支架内部再连接一个直管型覆膜支架,通常称为内分支。覆膜支架重建分支动脉时,都需要建立从覆膜支架上的孔到分支动脉的导丝轨道。
但是手术过程中内分支的导丝通道很难建立,为了简化手术的操作,支架系统会在内分支里准备好预置导丝,手术过程中使用抓捕器将预置导丝抓捕后拉出,可以建立贯穿内分支的导丝通道,预置导丝预置在输送器中,但是实际使用过程需要预置导丝长度远大于输送器的长度,所以大部分预置导丝都在体外。预置导丝如果有任何损伤,比如弯折、缠绕或者涂层脱落,都会影响其使用性能。
一般将导丝放在盘管中,来保护导丝不受外界影响,但对于预置在输送器中的预置导丝,由于预置导丝的盘管需要和输送器一起装配,应该尽可能的小,而体积的减小,为了保证能装入相同的长度的预置导丝,要求盘管尽可能靠近圆心进行盘卷。当将直的、有弹性的预置导丝送进盘管时,越靠近圆心,预置 导丝和盘管壁的摩擦力会越大,这会导致预置导丝无法装入盘管,或者装好的预置导丝不易抽出的问题。

根据本实用新型中的盘管,通过在第一支架的反向设置的第一安装面和第二安装面上,分别设有多个与至少一个盘管本体相卡接的多个第一安装槽,当至少一个盘管本体与第一支架连接时,至少一个盘管本体以环状或螺旋状的形式卡接于第一安装面和第二安装面的多个第一安装槽内,从而使盘管形成双层结构,同样面积内的本实用新型中的盘管,能够存放的导丝的长度相对于单层的盘管能够存放的导丝的长度增加了一倍,从而在存放同样长度的导丝的情况下,本实用新型中的盘管的能够远离环状或螺旋状的中心设置,从而减小导丝和盘管壁之间的摩擦力,便于将导丝装入盘管内,以及便于将盘管内的导丝进行抽出。

实施方式一
图1为本实用新型的实施方式一中盘管100的部分结构示意图。图2为图1中第一支架20的部分结构示意图。结合图1和图2所示,本实施方式中的盘管100包括一个中空的盘管本体10和一个第一支架20,第一支架20包括反向设置的第一安装面221和第二安装面222,第一安装面221和第二安装面222上分别设有多个第一安装槽223,盘管本体10卡接于多个第一安装槽223内,并使盘管本体10呈螺旋状设置。
具体的,本实施方式中的盘管本体10为可变形件,优选为塑料构件,易弯折且重量轻,盘管本体10呈螺旋状卡接于多个第一安装槽223内。盘管本体10被第一支架20固定后,整体近似圆形或椭圆形,从而能够尽可能的减小盘管本体10的空间占用率。第一支架20包括中间段21和分别设于中间段21的两端的连接段22,两端的连接段22分别具有第一安装面221和第二安装面222。
通过在第一安装面221和第二安装面222上分别设有多个能够与盘管本体 10相卡接的多个第一安装槽223,且第一安装面221和第二安装面222反向设置在第一支架20上,当盘管本体10与第一支架20连接时,其中一种实施方式为,盘管本体10从第一安装面221的最外侧的第一安装槽223穿入,并沿螺旋状经过多次盘卷直至靠近中间段21的第一安装槽223内,从而完成第一安装面221上对盘管本体10的固定。然后将盘管本体10的其余部分沿第二安装面222的靠近中间段21的第一安装槽223继续盘卷,直到盘管本体10盘卷至第二安装面222的最外侧的第一安装槽223,从而完成对盘管本体10整体的固定。在此过程中,由于第一安装面221和第二安装面222均盘卷有盘管本体10,使盘管100呈双层结构。双层结构的好处在于,对比于单层盘管结构,为了能容纳更长的预置导丝,盘管必须继续向内螺旋排布,随着直径的变小,每一环能容纳的长度越来越小,而随着直径的变小,导丝的回弹力越来越大,导致盘管和导丝间的摩擦力越来越大,导致导丝无法插入盘管内,或者无法从盘管内抽出。而双层的盘管100在盘管本体10沿径向方向向内盘卷一定尺寸后,可以由一个安装面切换至另一个安装面,并继续沿径向方向向外盘卷,径向尺寸逐渐增大,从而有效地减小导丝和盘管本体10的内壁之间的摩擦力,便于将导丝装入盘管本体10内,以及便于将盘管本体10内的导丝进行抽出。
同时,第一支架20对盘管本体10起到束缚作用,由于盘管本体10和导丝自身具有回弹力,盘卷后的盘管本体10会自然形成圆形,通过第一支架20的束缚作用,能够最大限度地减小盘管本体10形成椭圆形,从而利于盘管100装配到尺寸较小的包装中。
图3为图1中第二支架30的部分结构示意图。结合图1和图3所示,本实施方式中的盘管100还包括第二支架30,第二支架30上反向设置的两个端面上各自分别设有多个第二安装槽31,盘管本体10的一部分卡接于多个第二安装槽31内,多个第二安装槽31的位置和数量分别与多个第一安装槽223的位置和数量对应设置。
结合图1、图2和图3所示,两端的连接端22的相同安装面上均设有四个第一安装槽223,对应的使缠绕后的盘管本体10形成径向分布的四环结构,为了保证盘管本体10在各个环中的整齐有序,对应的第二安装槽31的数量与第一安装槽223数量一致,同样为四个。本实施方式中仅在第一支架20的两个侧 面上设置第一安装槽223,因此,第二支架30上也仅在两个相对的侧面上设置第二安装槽31。
其中,第一安装槽223和第二安装槽31的数量取决于盘管本体10盘卷的周数,当盘管本体10所需存放的导丝过长从而造成盘管本体10的盘卷周数较多时,第一安装槽223和第二安装槽31的数量可相应增加,同理,也可相应减少第一安装槽223和第二安装槽31的数量。第一安装槽223和第二安装槽31的底面为弧形面,该弧形面的半径优选为与盘管本体10的半径相等,且弧形的弧长稍大于盘管本体10的横截面的外周周长的一半,这样,第一支架20可以使得盘管本体10盘卷成螺旋状后保持稳定,不会轻易松散开。在本实用新型的其他实施方式中,第一安装槽223和第二安装槽31的底面弧形的半径也可稍大于或稍小于盘管本体10的半径,只要保证盘管本体10不会轻易松散即可。
可以理解的是,为保证盘卷后的盘管本体10的稳定,可以根据实际需求在盘管本体10上设置相应数量的第一支架20和第二支架30,本实用新型不对第一支架20和第二支架30的具体使用数量和使用位置做限制。
图4为本实用新型一实施方式中盘管100在收容导丝200后构成的横截面结构示意图。如图4所示,在本实用新型的一些实施方式中,盘管本体10为中空管,盘管本体10的管腔内设有连接中空管内壁的一个直线形的隔板40,从而通过直线形的隔板40将盘管本体10的管腔分割成互不相通的两个管腔。
通过在管腔内设置隔板40并将管腔分割成两个互不相同的管腔,一方面能够在两个管腔内分别收容一个导丝200,从而增加了导丝200的存放数量且不需要额外增加盘管100。另一方面,当盘管本体10的存放空间不够时,导丝200可以在穿满盘管本体10的一个管腔后继续沿另一个管腔进行穿设,从而能够进一步地提高盘管100的存放导丝200的长度。
其中,盘管本体10的外轮廓可以有多种形式,优选为圆形。圆形的外轮廓可以很容易固定在第一安装槽223中,从而利于盘管本体10进行装配。隔板40有多种设置形式,直线形的隔板40结构简单,不影响盘管100的柔顺性,且导丝200在盘管本体10内与隔板40的接触面积最少,可以很好的减少摩擦力。盘管本体10的壁厚和隔板40的壁厚优选在0.2-0.5mm,壁厚太小容易破裂,壁厚太大会影响盘管本体10的柔顺性,在弯曲过程中容易折断。
图5为本实用新型另一实施方式中盘管100在收容导丝200后的横截面结构示意图。如图5所示,该实施方式中盘管本体10的外轮廓为圆形,隔板40为S形。
图6为本实用新型另一实施方式中盘管100在收容导丝200后的横截面结构示意图。如图6所示,该实施方式中盘管本体10的外轮廓为圆形,隔板40为沙漏形。
图7为本实用新型另一实施方式中盘管100在收容导丝200后的横截面结构示意图。如图7所示,该实施方式中盘管本体10的外轮廓为圆形,管腔内设有人字形分布的隔板40,从而使管腔内部分割成三个互不相通的管腔。
图8为本实用新型另一实施方式中盘管100在收容导丝200后的横截面结构示意图。如图8所示,该实施方式中盘管本体10的外轮廓为椭圆形,隔板40为直线形。
实施方式二
图9为本实用新型的实施方式二中第一支架20的部分结构示意图。如图9所示,本实施方式中的技术方案与实施方式一中的技术方案大体一致,不同之处在于,本实施方式中的第一支架20的连接段22上,位于第一安装面221和第二安装面222之间的端面224上也设有两个第一安装槽223。
当对盘管本体10进行盘卷时,其中一种实施方式为,首先从第一安装面221上靠近中间段21的第一安装槽223进行盘卷,当盘卷至连接段22最外侧的第一安装槽223时,完成对第一安装面221上盘管本体10的盘卷。接着按照图9中所示位置从端面224上方的第一安装槽223盘卷至端面224下方的第一安装槽223,再从第二安装面222的最外侧的第一安装槽223继续盘卷,直至到达靠近中间段21的第一安装槽223,从而完成对盘管本体10的盘卷过程,并使盘管本体10呈四层结构。若想继续增加盘管本体10盘卷后的层数,可对应增加端面224上第一安装槽223的数量。
图10为本实用新型的实施方式二中第二支架30的部分结构示意图。对应的,本实施方式中的第二支架30,除了在反向设置的两个端面上各自设置多个第二安装槽31,还在第二支架30的其中一个侧端面上也设置有两个第二安装 槽31,从而使得盘管本体10在第一支架20和第二支架30的配合下,被盘卷的整齐有序。
实施方式三
图11为本实用新型的实施方式三中盘管100收容导丝200后的部分结构示意图。如图11所示,本实施方式中盘管100包括多个盘管本体10和多个第一支架20,多个盘管本体10的径向尺寸可以相等或不等。各个盘管本体10分别卡接于两个第一支架20上的多个第一安装槽223内。每个盘管本体10包括两个开口相对且间隔一定距离设置的C形子盘管11。子盘管11的两端分别卡接于第一支架20的一个第一安装槽223内,两个C形子盘管11的开口相对设置。导丝200穿设于每个盘管本体10的管腔内,且在盘管本体10的两个子盘管11之间间隔开的位置处裸露出导丝200的一部分。
具体的,盘管100整体可以呈圆形或椭圆形。盘管100可收容一个或多个导丝200。以收容多个导丝200为例,多个导丝200分别各自穿设在一个盘管本体10内,且每个导丝200均在相应的盘管本体10的两个子盘管11之间裸露出一部分。例如图11中最外一层的椭圆形部分,位于两个子盘管11之间的两个平行的直线段,即为裸露出的导丝200的一部分。这样设计的好处在于在导丝200被拉出而受力时,导丝200的受力方向和导丝200被拉出的路径是同一方向,不会导致导丝200因拉出而变形。同一盘管本体10的两个子盘管11之间的间隔部分,能够减小盘管本体10和导丝200间的摩擦力,同时也有利于导丝200在不同径向位置的盘管本体10间的切换。同一盘管本体10的两个子盘管11之间间隔的距离越大,也即收容导丝200后裸露在外的长度越长,则卡接其中一个子盘管11的第一支架20,与卡接另一个子盘管11的另一个第一支架20之间的间隔距离越大。
盘管100可以是双层或更多层结构,也可以是在管腔内设置隔板40的单层结构,盘卷方式和具体实施方式一中的盘卷方式一样,从而增加盘管100的整体长度。进一步地,由于本实施方式中,构成盘管本体10的两个子盘管11不是实体连续的,因此本实施方式中的第一支架20的数量为两个,且两个第一支架20平行设置,其中一个第一支架20上的多个第一安装槽223分别与另一个 第一支架20上的多个第一安装槽223两两相对设置。进一步地,两个第一支架20间可通过一个连接杆50相连,从而将多个盘管本体10进行连接并固定下来。连接杆50的长度越大,则两个第一支架20之间间隔的距离越大,因而导丝200裸露在外的直线段越长,能够更大程度地减小盘管本体10和导丝200间的摩擦力,使得导丝200在盘管本体10内的抽拉更容易。
在其他实施方式中,上述盘管本体10可卡接在两个以上的第一支架20上。两个第一支架20之间也可以通过两个或两个以上的连接杆50进行连接,以增强连接的牢固性,同时避免盘管本体10局部受力后导致盘管100整体变形。
在其他实施方式中,如图11所示的盘管100,C形子盘管11的中间段部分也可以是断开的,也即,C形子盘管11可仅保留与第一支架20卡接的一部分,也就是仅保留C形子盘管11的两个端部附近的部分即可。进一步地,可将位于最外部的两个子盘管11保留为C形,以避免位于最外侧的导丝200受到损伤,以及避免导丝200抽出时由于导丝200在该位置处弯曲较大而与子盘管11的端部之间的摩擦较大,容易刮伤子盘管11的端部。
结合图4和图11所示,本实用新型的盘管100,用于收容设于盘管本体10的管腔内的一个或多个导丝200,也可以用于收容其他类似导丝200的线状件。
对比于单层盘管结构,本实施方式中的盘管100能够容纳更长或更多数量的导丝200,且有效地减小导丝200和盘管本体10内壁之间的摩擦力,便于将导丝200装入盘管本体10内,以及便于将盘管本体10内的导丝200进行抽出。
以上所述,仅为本实用新型较佳的具体实施方式,但本实用新型的保护范围并不局限于此,任何熟悉本技术领域的技术人员在本实用新型揭露的技术范围内,可轻易想到的变化或替换,都应涵盖在本实用新型的保护范围之内。因此,本实用新型的保护范围应以权利要求的保护范围为准。
