具体实施方式
现在将参考附图更全面地描述示例实施方式。然而,示例实施方式能够以多种形式实施, 且不应被理解为限于在此阐述的实施方式;相反,提供这些实施方式使得本申请将全面和完整,并将示例实施方式的构思全面地传达给本领域的技术人员。图中相同的附图标记表示相同或类似的结构,因而将省略它们的详细描述。
如图1所示,图1示出的是本申请实施例的医疗器械系统的示意图。本申请实施例的医疗器械系统包括输送装置10、可植入装置8和装载器7。输送装置10用于通过介入治疗的方式将可植入装置8输送并植入至患者体内。装载器7套设在输送装置10的外围,用于将可植入装置8载入输送装置10。
可以理解的是,本申请实施例中的术语“包括”和“具有”以及它们任何变形,意图在于覆盖不排他的包含。例如包含了一系列步骤或单元的过程、方法、系统、产品或设备没有限定于已列出的步骤或单元,而是可选地还包括没有列出的步骤或单元,或可选地还包括对于这些过程、方法、产品或设备固有的其它步骤或组件。
可植入装置8可以是心脏封堵器、血管封堵器、血管滤器等类型。本申请中以可植入装置8为左心耳封堵器为例进行说明,可以理解的是,可植入装置8还可以是其他类型可植入装置。
如图2所示,图2示出的是本申请实施例的可植入装置8的示意图。作为一示例,可植入装置8为左心耳封堵器,包括可膨胀体88以及设置于可膨胀体88上的第一连接件83和第二连接件84。第一连接件83和第二连接件84在可植入装置8的轴向方向上间隔设置,且用于与输送装置10连接。例如,第一连接件83与输送装置10的外鞘管组件2的远端可拆卸连接,第二连接件84与输送装置10的内鞘管组件5的远端可拆卸连接,后续将详细说明。
可膨胀体88包括密封盘81和锚定盘82,密封盘81和锚定盘82在可植入装置8的轴向方向上间隔设置,并且密封盘81设置在锚定盘82的近端。第一连接件83设置在第二连接件84的近侧,具体的,第一连接件83设置在密封盘81上,第二连接件84设置在锚定盘82上。
需要说明的是,在本申请实施例中,术语“远端”、“远侧”、“近端”、“近侧”是以在手术过程中沿着输送路径相对于操作输送装置10的操作者的远近来界定。具体来说,某一部件沿着输送路径靠近操作者的一端/侧为“近端”/“近侧”,沿着输送路径远离操作者的一端/侧为“远端”/“远侧”。
作为一示例,可植入装置8被释放至左心耳口部,第一连接件83和第二连接件84分别与输送装置10解脱后,输送装置10的远端撤离体外。举例来说,第一连接件83和第二连接件84均可以与输送装置10为周向旋转解脱的连接关系,例如第一连接件83与输送装置10为螺纹连接,第二连接件84与输送装置10为螺纹连接。
当然,在一些实施方式中,第一连接件83和第二连接件84与输送装置10之间还可以是插拔解脱的连接关系。在一些实施方式中,第一连接件83与外鞘管组件2的远端间接连接,及/或第二连接件84与内鞘管组件5的远端间接连接。
在本实施方式中,密封盘81与锚定盘82可以均由导电材料制成,密封盘81采用骨架导电,第一连接件83与密封盘81骨架电连接,锚定盘82设置有用于导电的电极821,第二连接件84与锚定盘82的电极821电连接。第一连接件83与第二连接件84还都用于传输电能。
作为一示例,如图2所示,第一连接件83与第二连接件84之间还设置有多个固定件,分别为第一固定件85、第二固定件86和第三固定件87。这些固定件用于连接密封盘81与锚定盘82,并起到绝缘作用。
具体来说,密封盘81呈网状,可以由编织或切割工艺制造,第一连接件83连接于密封盘81的近端,优选地还用于收束密封盘81中编织丝的近端。第一固定件85设置于密封盘 81的远端,优选地,第一固定件85还用于收束密封盘81编织丝的远端。第一固定件85可以由导电材料制成也可以由绝缘材料制成。在一些实施方式中,密封盘81表面设置有膜体用于实现阻流、及/或绝缘等作用。膜体可以设置于密封盘81的至少部分外侧表面,及/或设置于密封盘81的至少部分内表面。
锚定盘82可以由编织工艺或切割工艺制成,锚定盘82的端部收束在一起,并压紧在第二固定件86和第三固定件87之间,第二固定件86和第三固定件87可以均由绝缘材料制成。第二连接件84设置在第三固定件87的远端,从而保证密封盘81与锚定盘82之间的绝缘,以及锚定盘82与第二连接件84之间的绝缘。在一些实施方式中,锚定盘82表面设置有膜体用于实现阻流、及/或绝缘等作用。膜体可以设置于锚定盘82的至少部分外侧表面,及/或设置于锚定盘82的至少部分内表面。
可以理解的是,上述描述仅仅以图2为示例来说明可膨胀体88,图2中可膨胀体88包括密封盘81、锚定盘82,为双盘结构。在其他实施方式中,可膨胀体88为其他结构形式,比如为单盘结构或者是三盘结构或者更多盘结构,比如可膨胀体88为单盘结构并呈柱塞状。
上述描述仅仅以图2为示例来说明密封盘81、锚定盘82之间如何实现绝缘。当然,在其他实施方式中,第一连接件83与第二连接件84之间还采用其他的方式实现绝缘。
如图3所示,图3示出的是本申请实施例的输送装置10的示意图。本申请实施例的输送装置10,包括外鞘构件100和内鞘构件200,内鞘构件200可活动地穿设于外鞘构件100内。外鞘构件100的远端能够与可植入装置8的第一连接件83可拆卸地连接。内鞘构件200的远端能够与可植入装置8的第二连接件84可拆卸地连接。
在一实施方式中,外鞘构件100的远端与第一连接件83之间可以为插拔连接或周向旋转连接。当为周向旋转连接时,可以为螺纹连接。内鞘构件200的远端与第二连接件84之间可以为插拔连接或周向旋转连接。当为周向旋转连接时,可以为螺纹连接。
如图4所示,图4示出的是本申请实施例的外鞘构件100的示意图。外鞘构件100包括外鞘手柄1和外鞘管组件2。至少部分的外鞘管组件2设置于外鞘手柄1远侧。外鞘手柄1和外鞘管组件2均在各自的近端与远端之间形成空腔,两个空腔相连通。外鞘管组件2包括外鞘软管21和外导电头22,外导电头22设置在外鞘软管21的远端,用于与第一连接件83连接。外导电头22与第一连接件83的连接方式可以为插拔连接或周向旋转连接。当操作者操作外鞘手柄1时,能够带动外鞘管组件2做同步运动。外鞘手柄1用于供操作者操作,以带动外鞘管组件2运动,例如带动外鞘管组件2产生周向旋转运动和/或轴向移动,以使外鞘构件100与可植入装置8的第一连接件83实现连接、解脱,并能够用于带动第一连接件83移动。
如图5所示,图5示出的是本申请实施例的内鞘构件200的示意图。内鞘构件200包括内鞘手柄4和内鞘管组件5。至少部分的内鞘管组件5设置于内鞘手柄4远侧,内鞘管组件5用于穿设于外鞘构件100的两空腔。内鞘手柄4用于供操作者操作,以带动内鞘管组件5做同步运动,例如带动内鞘管组件5产生周向旋转运动和/或轴向移动。内鞘管组件5包括内鞘软管51和内导电头52,内导电头52设置在内鞘软管51的远端,用于与第二连接件84连接。内导电头52与第二连接件84的连接方式可以为插拔连接或周向旋转连接。当操作者操作内鞘手柄4时,能够带动内鞘管组件5运动。
请继续参阅图3,至少部分的内鞘手柄4外露于外鞘手柄1。通过操作内鞘手柄4,可使内鞘构件200相对于外鞘构件100在周向和/或轴向上产生运动,以使内鞘构件200与可植入装置8的第二连接件84实现连接、解脱,并能够用于带动第二连接件84移动。
在本实施例中,内鞘手柄4和外鞘手柄1在轴向上间隔设置。换言之,内鞘手柄4完全显露于外鞘手柄1。通过内鞘手柄4和外鞘手柄1在轴向上间隔设置,可使内鞘手柄4和外鞘手柄1在径向上不存在重叠结构,进而减小外鞘手柄1在径向上的尺寸。另外,内鞘手柄4完全显露于外鞘手柄1,更加方便操作者操作内鞘手柄4,例如操作内鞘手柄4实现轴向移动和/或周向旋转。
外鞘手柄1以及内鞘手柄4沿轴向依次设置,用于接受操作者的操控。操作者可以一只手握持外鞘手柄1,另一只手握持内鞘手柄4,操作者可以操作内鞘手柄4相对于外鞘手柄1产生轴向或者周向上的相对运动,以控制内鞘管组件5与外鞘管组件2产生相应的相对运动。
当然,在一些实施方式中,内鞘手柄4的远端可以隐藏在外鞘手柄1内,而内鞘手柄4的近端显露于外鞘手柄1。操作者可操作内鞘手柄4的近端,从而驱动内鞘构件200沿轴向和/或周向运动。
内鞘手柄4设置在输送装置10的近端,内鞘管组件5能够在内鞘手柄4的带动下,从外鞘构件100的空腔中向近侧移动直至与外鞘构件100完全脱离。换句话说,内鞘构件200相对于外鞘构件100在轴向上能够产生不限长度的轴向移动,使得内鞘构件200能够与外鞘构件100完全脱离。通过这样的设计,更加方便后续外鞘构件100与可植入装置8的旋转解脱,避免外鞘构件100与可植入装置8的旋转解脱的过程中,外鞘手柄1需要克服其近端穿出的内鞘手柄4以及内鞘管组件5带来的阻力。
具体来说,内鞘构件200、外鞘构件100与可植入装置8解脱时,可以采用的方式是:内鞘构件200的内导电头52与第二连接件84解脱之后,直接将内鞘构件200从患者体内撤出,即内鞘构件200从外鞘构件100的近侧完全抽离外鞘构件100,与外鞘构件100完全脱离。接着再将外鞘构件100的外导电头22与第一连接件83解脱。在外鞘构件100与第一连接件83的解脱过程中,由于内鞘构件200与外鞘构件100已完全脱离,故在外鞘构件100的旋转解脱过程中,内鞘构件200并不会影响外鞘构件100的旋转运动,使得外鞘构件100的旋转解脱更加便捷。
当然,内鞘构件200能够与外鞘构件100完全脱离的优点同样适用于外鞘构件100与第一连接件83为插拔的连接方式。
在其他实施方式中,内鞘构件200、外鞘构件100与可植入装置8解脱,还可以采用如下的解脱方式:内鞘构件200的内导电头52先与第二连接件84解脱,之后再将内鞘构件200向近侧移动一段距离,避免内鞘手柄4距离外鞘手柄1太近,导致操作者不容易操作外鞘手柄1,此时内鞘构件200中的内鞘管组件5还位于外鞘构件100内部。接着再将外鞘构件100的外导电头22与第一连接件83解脱,最后内鞘构件200和外鞘构件100一同从患者体内撤出。
本申请实施例的输送装置10,包括外鞘构件100和内鞘构件200,外鞘构件100包括外鞘手柄1以及与外鞘手柄1连接的外鞘管组件2,内鞘构件200包括内鞘手柄4以及与内鞘手柄4连接的内鞘管组件5。外鞘手柄1可供操作者操作,以带动外鞘管组件2运动,内鞘手柄4可供操作者操作,以带动内鞘管组件5运动。通过至少部分内鞘手柄4外露于外鞘手柄1的设计,使得操作者可直接操作内鞘手柄4,从而单独控制内鞘管组件5的运动,进而简化了手柄结构,并且方便操作者操作。
如图6至图8所示,图6示出的是本申请实施例的输送装置10的局部剖视图。图7示出的是本申请实施例的锁紧构件6的示意图。图8示出的是本申请实施例的锁紧构件6的剖视图。输送装置10还包括锁紧构件6,锁紧构件6连接在外鞘手柄1与内鞘管组件5之间,锁 紧构件6能够在锁紧状态和解锁状态之间相互转换。在解锁状态下,外鞘构件100和内鞘构件200能够产生相对运动,在锁紧状态下,锁紧构件6产生形变并夹紧内鞘管组件5,从而阻止内鞘构件200与外鞘构件100产生相对运动。
当锁紧构件6处于锁紧状态下时,能够阻止内鞘构件200与外鞘构件100产生相对运动,在可植入装置8的输送以及释放时,能够避免操作者误操作内鞘构件200。
可以理解的是,阻止内鞘构件200与外鞘构件100的相对运动包括周向运动和轴向运动。
在一实施方式中,部分锁紧构件6设置于外鞘手柄1的空腔中,内鞘管组件5穿设于锁紧构件6。
锁紧构件6包括第一锁紧管61、第二锁紧管62、挤压件63和夹持件64。第一锁紧管61沿轴向可移动地设置在外鞘手柄1的空腔内,内鞘管组件5穿设于第一锁紧管61内。第二锁紧管62沿轴向固定且沿周向可旋转地连接于外鞘手柄1,第二锁紧管62用于带动第一锁紧管61相对于第二锁紧管62沿第一锁紧管61的轴向产生相对移动。作为一示例,第二锁紧管62的外周可以凸设有沿轴向间隔设置的两个第一限位部,外鞘手柄1的空腔的内壁设有沿轴向间隔设置的两个第二限位部,两个第二限位部分别与两个第一限位部相止挡,使得两个第二限位部限制第二锁紧管62沿轴向的位移。
挤压件63设置在第一锁紧管61、第二锁紧管62或外鞘手柄1上。夹持件64设置在第一锁紧管61和/或第二锁紧管62上,在第二锁紧管62旋转带动第一锁紧管61相对于第二锁紧管62沿第一锁紧管61的轴向产生相对移动的过程中,夹持件64至少在径向上受挤压件63挤压产生形变而夹持内鞘管组件5。
在本实施例中,第二锁紧管62套设于第一锁紧管61的外围,夹持件64设置在第一锁紧管61的近端,挤压件63设置于第二锁紧管62的内壁表面。当第二锁紧管62旋转时,能够带动第一锁紧管61相对于第二锁紧管62沿第一锁紧管61的轴向向近端移动,使得夹持件64逐渐靠近挤压件63。当夹持件64和挤压件63接触时,夹持件64至少在径向上受挤压件63挤压产生形变而夹持内鞘管组件5。进一步地,夹持件64与第一锁紧管61为一体成型,挤压件63与第二锁紧管62为一体成型。可以理解的是,在变更实施方式中,夹持件64与第一锁紧管61可以不是一体成型,比如固定连接或者可拆卸连接;挤压件63与第二锁紧管62可以不是一体成型,比如固定连接或者可以可拆卸连接。
当然,在一些实施方式中,当夹持件64设置在第一锁紧管61时,挤压件63还可以设置在外鞘手柄1上。举例来说,夹持件64设置在第一锁紧管61的远端,挤压件63凸设在外鞘手柄1的空腔的内壁面。当第二锁紧管62旋转时,能够带动第一锁紧管61相对于第二锁紧管62沿第一锁紧管61的轴向并向远端移动,使得夹持件64逐渐靠近挤压件63,直至夹持件64和挤压件63接触时,夹持件64至少在径向上受挤压件63挤压产生形变而夹持内鞘管组件5。
此外,在一些实施方式中,夹持件64可以设置在第二锁紧管62,挤压件63设置在第一锁紧管61。第一锁紧管61套设于第二锁紧管62的外周。当第二锁紧管62旋转时,能够带动第一锁紧管61沿轴向移动,最终实现夹持件64至少在径向上受挤压件63挤压产生形变而夹持内鞘管组件5。
可以理解的是,当夹持件64设置在第二锁紧管62时,挤压件63可以设置在第一锁紧管61的远端。
当然,在一些实施方式中,夹持件64以可拆卸地方式连接于第一锁紧管61和第二锁紧管62之间,第一锁紧管61和第二锁紧管62一体成型有挤压件63。第一锁紧管61和第二锁 紧管62相螺接。部分的夹持件64伸入第一锁紧管61内,部分的夹持件64伸入第二锁紧管62内。夹持件64具有贯穿其近端和远端的穿孔,内鞘管组件5穿装于该穿孔。当第一锁紧管61相对于第二锁紧管62沿第一锁紧管61的轴向向近端移动时,夹持件64被第一锁紧管61和第二锁紧管62上的挤压件63共同挤压,使得夹持件64至少在径向上受挤压件63挤压产生形变而夹持内鞘管组件5。
可以理解的是,夹持件64可以采用弹性材料制成。进一步地,夹持件64为在径向上被挤压时沿径向弹性弯曲变形的弹性件,该弹性件例如由橡胶制成,但不以此为限。夹持件64还可以由铜材料制成,这样可提高夹持件64的耐磨性。
需要说明的是,夹持件64可以一体设置于第一锁紧管61上,夹持件64可以一体设置于第二锁紧管62上。例如,夹持件64一体设置于第一锁紧管61的近端,夹持件64一体设置于第二锁紧管62的远端。
挤压件63可以一体设置于第一锁紧管61上,挤压件63可以一体设置于第二锁紧管62上,挤压件63还可以一体设置于外鞘手柄1。
当然,夹持件64还可以可拆卸地连接于第一锁紧管61或第二锁紧管62。挤压件63也可以可拆卸地连接于第一锁紧管61、第二锁紧管62或外鞘手柄1。
第一锁紧管61和第二锁紧管62可以螺纹连接。第一锁紧管61具有外螺纹,第二锁紧管62具有内螺纹,第二锁紧管62套设于第一锁紧管61的外周,且螺纹连接。在一些实施方式中,第一锁紧管61具有内螺纹,第二锁紧管62具有外螺纹,第一锁紧管61套设于第二锁紧管62的外周,且螺纹连接。在一些实施方式中,第一锁紧管61和第二锁紧管62通过倾斜设置的导槽与导轨实现滑动连接。
请继续参阅图6至图8,第二锁紧管62包括第一管段621,第一锁紧管61穿设于第一管段621。第一管段621的内壁面可以具有内螺纹,第一锁紧管61的外周具有外螺纹,第一锁紧管61穿设于第一管段621,并与第一管段621螺纹连接。
挤压件63设置在第一管段621的近端,且倾斜向第二锁紧管62的轴线方向延伸,即挤压件63的近端向第二锁紧管62内部空间延伸,或者说挤压件63是倾斜的,挤压件63的近侧部分相对于其远侧部分距离第二锁紧管62的轴线更近。由于挤压件63倾斜向第二锁紧管62的轴线方向延伸,故当第一锁紧管61沿其轴向向近端移动时,夹持件64受到挤压件63的挤压而至少在径向上产生形变,进而夹持内鞘管组件5。
挤压件63的内壁面具有第一滑动面631,第一滑动面631的近端的径向尺寸相较于其远端的径向尺寸较小,即第一滑动面631中近侧部分是收拢的,用于与夹持件64的近端滑动配合,且至少在径向上挤压夹持件64。
在本实施例中,第一滑动面631的径向尺寸由远端至近端逐渐减小,使得夹持件64能够与第一滑动面631实现较好的滑动配合,在夹持件64和挤压件63滑动配合的过程中,夹持件64至少在径向上产生形变。第一滑动面631的径向尺寸逐渐缩小的设计,更有利于夹持件64在径向上产生形变。在一些实施方式中,第一滑动面631为锥面或弧面。
夹持件64的近端具有第二滑动面641,第二滑动面641用于与第一滑动面631滑动配合,使得至少在径向上第一滑动面631能够挤压第二滑动面641,以使夹持件64产生形变而夹持内鞘管组件5。
可以理解的是,第一滑动面631和第二滑动面641可以为平面或曲面。举例来说,第一滑动面631和第二滑动面641可以均为平面,也可以均为曲面,还可以是一个为平面,另一个为曲面。
在本实施例中,第一滑动面631和第二滑动面641均为锥面。
在一些实施方式中,在锁紧状态下,第一滑动面631和第二滑动面641相互脱离,且第二滑动面641移动至第一滑动面631的近端或近侧。在一些实施方式中,在锁紧状态下,第一滑动面631和第二滑动面641相互抵接。
第二锁紧管62还包括第二管段622,第二管段622连接在挤压件63的近端。也就是说,由远端至近端,第二锁紧管62依次包括第一管段621、挤压件63和第二管段622。锁紧构件6还包括旋钮65,旋钮65固定连接于第二锁紧管62,并显露于外鞘手柄1。旋钮65外露于外鞘手柄1,用于接收操作者的周向旋转操作。
请继续参阅图7与图8,第一锁紧管61的近端设有夹持件64,第一锁紧管61的远端设有限位部611,限位部611呈筒状,便于内鞘管组件5从中穿设。限位部611在垂直于轴向的横截面上呈方框状,包括相对设置的顶壁与底壁,以及连接在顶壁与底壁之间的两个相对设置的侧壁。该两侧壁用于与外鞘手柄1限位配合,使得第一锁紧管61仅能够沿其轴向移动,而不能沿周向旋转。在其他实施方式中,该顶壁与底壁用于与外鞘手柄1限位配合,使得第一锁紧管61仅能够沿其轴向移动,而不能沿周向旋转。
夹持件64设置于第一锁紧管61的近端,其包括多个沿周向间隔设置的夹爪642,沿周向方向,相邻的两个夹爪642之间具有间隙。在挤压件63的挤压作用下,多个夹爪642的近端产生形变相互靠拢,而夹持内鞘管组件5。每个夹爪642的近端外侧设置有上述第二滑动面641。
如图4和图9所示,图9示出的是本申请实施例的外鞘构件100的局部剖视图。外鞘手柄1包括外手柄壳体11和第一注液接头12,外手柄壳体11围成外鞘手柄1的空腔,第一注液接头12设置在外鞘手柄1的空腔内,且与外鞘管组件2的近端连通。外手柄壳体11包括外鞘接口部111,外鞘接口部111形成有第一开口112,外鞘手柄1中的空腔延伸至外鞘接口部111,并贯通至第一开口112,第一注液接头12是设置于外鞘接口部111中,通过第一开口112显露于外手柄壳体11表面,用于与第一注射装置(图中未示出)连接,第一注射装置通过第一注液接头12向外鞘管组件2提供液体。可以理解的是,第一注射装置提供的液体包括但不限于生理盐水、显影剂或者是其他的一些药物等。
外鞘手柄1还包括第一导电接头13,第一导电接头13设置在外鞘手柄1的空腔内,具体是设置于外鞘接口部111中,且与外鞘管组件2电连接,第一导电接头13穿出外鞘接口部111设有第一开口112的端面而显露于外鞘手柄1表面,用于与第一外部电源(图中未示出)连接,第一外部电源通过第一导电接头13向外鞘管组件2提供电能。可以理解的是,第一外部电源提供的电能能够传递至可植入装置8的第一连接件83。
外鞘接口部111凸设于外手柄壳体11的外壁,第一开口112设置于外鞘接口部111远离外手柄壳体11的一端,外鞘接口部111的凸伸方向相对于外手柄壳体11的轴线倾斜,第一开口112朝向外手柄壳体11的近端。
外鞘接口部111凸设于外手柄壳体11的外壁,可缓解外鞘手柄1的空腔体积不足的问题。此外,外鞘接口部111相对于外手柄壳体11的轴线倾斜设置,且外鞘接口部111的用于设置第一开口112及第一导电接头13的端面朝向外手柄壳体11的近端,这样方便操作者插接第一注射装置以及第一外部电源。
如图10至图12所示,图10示出的是本申请实施例的第一注液接头12的示意图。图11示出的是本申请实施例的第一注液接头12的分解示意图。图12示出的是本申请实施例的第一注液接头12的剖视图。本申请实施例的第一注液接头12包括阀体14和启闭组件15,阀 体14形成接收通道141和流体通道142,接收通道141与第一开口112连通,用于接收第一注射装置的注射端,流体通道142与外鞘管组件2连通。启闭组件15形成有切口151,切口151贯穿启闭组件15的厚度方向的两个相对的侧面,启闭组件15设于接收通道141与流体通道142之间,第一注射装置的注射端用于沿着接收通道141穿过切口151进入流体通道142,并向流体通道142注射液体,液体流经流体通道142进入外鞘管组件2的内腔。
可以理解的是,本申请实施例的第一注液接头12设置在外鞘手柄1的空腔内,第一注液接头12的接收通道141能够接收第一注射装置的注射端,注射端能够沿着接收通道141穿过切口151进入流体通道142,从而使第一注射装置的液体沿着接收通道141穿过切口151进入流体通道142,最终进入外鞘管组件2的内腔。相比于相关技术中采用外接的三通阀向外鞘管组件2供给液体的方式,本实施例的第一注液接头12集成在外鞘手柄1中,一方面提高了外鞘手柄1的集成度,另一方面也方便外鞘构件100的周向旋转以及轴向运动。
启闭组件15包括弹性的垫片15a,垫片15a形成有切口151。在一实施方式中,切口151可以为“十”字型。当第一注射装置的注射端插入切口151时,切口151被撑开,注射端流出的液体能够经过流体通道142从第一注液接头12流出。切口151在自然状态下呈关闭状态,接收通道141与流体通道142被垫片15a隔离。
当切口151被撑开时,第一注液接头12能够接收第一注射装置的液体。当切口151关闭时,接收通道141与流体通道142被垫片15a隔离,确保外鞘构件100内腔的密封性,避免外界空气从第一注液接头12进入到外鞘管组件2内腔。
阀体14包括第一座体143和第二座体144,第一座体143与第二座体144可拆卸连接。第一座体143形成有接收通道141,第二座体144包括相互连接的通道部145和连接部146,连接部146与第一座体143可拆卸地连接,通道部145与连接部146形成有流体通道142。启闭组件15夹设在第一座体143和第二座体144之间。
在一实施方式中,连接部146与第一座体143可以通过螺纹连接,例如连接部146的外周具有外螺纹,第一座体143的内壁具有外螺纹。当然,还可以是连接部146套设于第一座体143的外周。
通过连接部146与第一座体143的螺纹连接的设计,可方便拆装第一座体143和第二座体144,从而方便组装以及更换垫片15a。在其他实施方式中,连接部146与第一座体143不限于通过螺纹连接,比如通过卡接,粘接等至少一种方式进行连接。
连接部146正对接收通道141的位置形成向远离接收通道141方向凹陷的容纳槽147,启闭组件15覆盖容纳槽147的开口,容纳槽147用于容纳第一注射装置的注射端,容纳槽147的底面形成用于抵接注射端的抵接面1471。接收通道141为等径通道,流体通道142为等径通道,等径通道为,通道的不同轴向位置处,径向尺寸相同,第一注射装置的注射端可以经由接收通道141以及流体通道142抵触抵接面1471。接收通道141与流体通道142的径向尺寸可以相同或不同。
第一注射装置的注射端插入第一注液接头12后,注射端穿过切口151后能够与容纳槽147的抵接面1471相抵接,当注射端与抵接面1471抵接后,操作者则知晓注射端已插接到位,提高了操作者的操作手感。
如图12和图13所示,图13示出的是本申请实施例的第二座体144的示意图。抵接面1471形成有向远离启闭组件15方向凹陷的导流槽148,且导流槽148与流体通道142连通。当第一注射装置的注射端与容纳槽147的抵接面1471抵接后,液体可通过导流槽148流入流体通道142。导流槽148的设计有利于液体流通,避免抵接面1471阻碍液体流入流体通道142。
在一实施方式中,导流槽148的形状可以为“十”形,但不以此为限。
如图6、图9和图14所示,其中图14示出的是本申请实施例的连接管17的两端分别连接外鞘接头16和第一注液接头12的示意图。外鞘手柄1还包括外鞘接头16和连接管17。外鞘接头16设置在外手柄壳体11的空腔中,且整体大致呈管状。外鞘接头16具有相互连通的主通道161和支通道162,外鞘管组件2的近端连接于外鞘接头16的远端,并与主通道161连通,内鞘管组件5穿设于主通道161中,并从主通道161的两端穿出。连接管17的一端与流体通道142连通,另一端与支通道162连通。
外鞘接头16包括端头167、中间件168和底座169。由远端至近端,端头167、中间件168和底座169依次可拆卸连接,如端头167与中间件168的一端螺纹连接,中间件168的另一端与底座169螺纹连接。
外鞘软管21的近端固定连接在外鞘接头16中。作为一示例,外鞘软管21的近端固定在端头167和中间件168之间,具体来说,外鞘软管21、端头167和中间件168的组装过程中,外鞘软管21的近端穿装在端头167的近端的穿孔内,并对外鞘软管21的近端进行扩口,使外鞘软管21的近端变形为锥筒状,并与端头167的近端穿孔的孔壁形状相适配,之后再将中间件168与端头167组装,使得呈锥筒状的外鞘软管21的近端被夹紧在端头167的穿孔的孔壁和中间件168的远端之间。
外鞘接头16还包括具有弹性的密封件165,密封件165设置在外鞘接头16的近端,例如夹设在中间件168的近端和底座169之间。密封件165的轴向上设置有供内鞘管组件5穿过的开孔166,例如开孔166可供加强管54和内鞘软管51穿过。
作为一示例,外鞘接头16用于连通第一注液接头12和外鞘管组件2,还通过设置密封件165以密封外鞘接头16的近端。
在本实施例中,端头167与中间件168设计为可拆卸的分体结构,便于外鞘软管21的近端的组装。中间件168与底座169设计为可拆卸的分体结构,便于密封件165的组装。
外鞘接头16包括主管道163和支管道164。主管道163形成主通道161,主管道163的远端连接外鞘软管21的近端,且主通道161连通外鞘软管21的内腔,以用于穿设内鞘管组件5。支管道164形成支通道162,且支通道162连通主通道161。其中,请结合图9、图14及图16,第一注液接头12的通道部145位于主管道163的轴线的一侧,支管道164旁接于主管道163的邻近通道部145的通道口的一侧管壁。可选地,支管道164的轴线与主管道163的轴线可以相互倾斜,也可以相互垂直。如图9及图14所示,作为一示例,支管道164和主管道163呈Y字型结构,支管道164的轴线与主管道163的轴线倾斜设置,且支管道164远离主管道163的一端向主管道163的近端延伸。连接管17的相对两端分别连通于通道部145的通道口以及支管道164的远离主管道163的一端管口。通过支管道164的轴线与主管道163的轴线倾斜设置,且支管道164向主管道163的近端延伸的设计,使得连接管17的两端分别连接支管道164和第一注液接头12的通道部145后,有利于增大连接管17两端之间的距离,减小连接管17的曲率与长度。
第一注射装置提供的液体依次流经第一注液接头12、连接管17、支管道164、主管道163、外鞘管组件2的近端,直至外鞘管组件2的远端。
在本实施例中,外鞘接头16的主管道163可以由端头167、中间件168和底座169共同形成,支管道164可以形成在中间件168。
请继续参阅图10、图12和图14,流体通道142的轴线和接收通道141的轴线相互错开,以使通道部145的外壁相对于连接部146的外壁形成一向流体通道142轴线方向凹陷的避让 空间149。外鞘接头16及/或外鞘管组件2穿过避让空间149,避免通道部145与外鞘接头16及/或外鞘管组件2相干涉。
在本实施例中,通过流体通道142的轴线和接收通道141的轴线相互错开的设计,一方面,使得通道部145和连接部146的外壁共同形成一空间较大的避让空间149,该避让空间149用于供外鞘接头16及/或外鞘管组件2穿过,这样可进一步提高外鞘手柄1的集成度,有效利用外手柄壳体11内的体积,减小了外鞘手柄1的尺寸;另一方面,第一注液接头12的通道部145远离外鞘接头16的支管道164的出口(即支管道164的远离主管道163的一端的管口),进而可调节连接管17的弯曲曲率与长度。
如图14所示,外鞘手柄1还包括定位结构18,定位结构18设置在外鞘手柄1的空腔的内壁,且位于外鞘手柄1的近端,用以将连接管17定位于外鞘手柄1的近端侧。
在一实施方式中,定位结构18可以包括定位柱181和定位框182。定位框182相较于定位柱181靠近近端。连接管17的一个区段(在图中为其中间部分)被定位在定位柱181和定位框182之间。
需要说明的是,定位框182从外手柄壳体11的内壁向外手柄壳体11的内部延伸,还形成一定位腔183,该定位腔183呈方框状,用于限制第一锁紧管61的限位部611(具体为其两侧壁)的周向移动。具体来说,第一锁紧管61的限位部611设置在定位腔183内,限位部611仅能够相对于定位框182沿着轴向移动,而不能周向旋转。
如图5和图15所示,图15示出的是本申请实施例的内鞘构件200的局部剖视图。内鞘手柄4包括内手柄壳体41和第二注液接头42,第二注液接头42设置在内手柄壳体41内,且与内鞘管组件5的近端连通。内手柄壳体41包括内鞘接口部411,内鞘接口部411形成有第二开口412,第二开口412用于实现第二注液接头42与第二注射装置(图中未示出)之间的连接,第二注射装置用于向内鞘管组件5提供液体。第二注射装置提供的液体包括但不限于生理盐水、显影剂或者是其他的一些药物等。可选地,在一实施方式中,第二注射装置可以通过三通阀44连接第二注液接头42,三通阀44的其中一阀口连接有管道,该管道远离三通阀44的一端通过第二开口412穿入内手柄壳体41内,从而与第二注液接头42进行连接(具体为连接于第二注液接头42的第二通道422,后文有详细描述)。
内鞘手柄4还包括呈管状的导丝口45,导丝口45与内鞘管组件5的内腔连通。导丝口45的一端显露于内鞘手柄4的表面,通过该导丝口45,可供导丝穿过导丝口45而进入内鞘管组件5的内腔。
第二注液接头42包括相连通的第一通道421和第二通道422。第一通道421的近端连通导丝口45,第一通道421的远端连通内鞘管组件5的内腔。第二通道422的近端用于与第二注射装置连通,第二通道422的远端连通第一通道421。第一通道421轴线和第二通道422的轴线倾斜设置,且第二通道422的近端向第一通道421的近端延伸。
内鞘手柄4还包括第二导电接头43,第二导电接头43设置在内手柄壳体41内,且与内鞘管组件5电连接,第二导电接头43穿出内鞘接口部411设有第二开口412的端面而显露于内鞘手柄4表面,用于与第二外部电源(图中未示出)连接,第二外部电源通过第二导电接头43向内鞘管组件5提供电能。
请继续参阅图5、图6和图15,内鞘管组件5包括内鞘软管51、加强管54和导套53。内鞘软管51穿装于外鞘构件100,具体来说,内鞘软管51穿装于外鞘管组件2、外鞘接头16和锁紧构件6。内鞘软管51的远端伸出外鞘管组件2的远端,并与可植入装置8的第二连接件84连接,内鞘软管51的近端伸出外鞘手柄1的近端,并与内鞘手柄4连接。同时,内 鞘软管51的近端伸入内手柄壳体41内,并与第二注液接头42连接。加强管54套设于内鞘软管51的外周,用于穿装于外鞘构件100的外鞘接头16中。在外鞘手柄1与内鞘手柄4之间的间距满足一定范围内的情况下(比如在外鞘手柄1和内鞘手柄4轴向间距最小的情况下,两者间距在0-5cm范围内的情况下,或其他输送与释放封堵装置过程中两手柄之间的其他间距范围),加强管54的远端伸出外鞘手柄1,加强管54的近端与导套53连接。导套53穿装于外鞘构件100的锁紧构件6,具体来说,导套53穿装于锁紧构件6的第一锁紧管61和第二锁紧管62。当锁紧构件6处于锁紧状态时,夹持件64用于夹持导套53的外周。并且在外鞘手柄1与内鞘手柄4之间的间距满足一定范围内的情况下(比如在外鞘手柄1和内鞘手柄4轴向间距最小的情况下,两者间距在0-5cm范围内的情况下,或其他输送与释放封堵装置过程中两手柄之间的其他间距范围),导套53的远端延伸至外鞘手柄1的内腔,且套设在加强管54的近端外周,导套53的近端伸出外鞘手柄1的近端,且与内手柄壳体41连接。
其中,导套53的硬度大于内鞘软管51的硬度。由于夹持件64夹持硬度较大的导套53,而未夹持硬度较小的内鞘软管51,使得导套53能够保护内鞘软管51,防止内鞘软管51被夹变形,而影响内部液体的流动。
此外,加强管54的硬度大于内鞘软管51的硬度,导套53的远端套设在加强管54的近端外周,这样便于内鞘手柄4一侧的力矩传递至相对硬度较差的内鞘软管51。
加强管54和内鞘软管51均穿设于外鞘接头16的密封件165的开孔166,由于加强管54套设在内鞘软管51的外周,故加强管54的外壁与密封件165直接接触。加强管54的硬度相较于内鞘软管51较高,使得内鞘管组件5穿置外鞘接头16的位置的材料硬度得到加强,加强管54起到保护内鞘软管51的作用,避免密封件165压迫内鞘软管51,破坏内鞘软管51的结构,影响内鞘软管51的轴向移动和周向旋转,以及其内部的液体传输。
