Description

一种医用装置 技术领域
本发明涉及医疗器械技术领域，具体涉及一种医用装置。
背景技术
涉及主动脉弓的动脉血管病变是非常复杂与危险的，医生往往会在开胸手术与微创伤介入手术之间做出选择。微创伤介入手术相比开胸手术具有创伤小、术后恢复快的优势，但其也存在一些问题，尤其是分支血管的处理，一直是各类产品的设计重点。
医生在执行微创伤介入手术时，大多采用DIY直管覆膜支架或一体化带有分支支架的主动脉覆膜支架系统，然而不论采用哪种支架系统，分支血管的通路建立都至关重要。现有技术中，在建立分支血管的通路时，一般采用导丝加导管的方式进行导入分支血管的操作，例如从下肢动脉如股动脉入路，并从主动脉往上导入分支动脉，或者，从上肢动脉和颈动脉入路，并从分支血管往下导入主动脉。具体操作一般是先植入一个带有开窗的主体覆膜支架，然后选择适应分支血管角度的导管，将此导管导引至分支血管附近，并利用导管远端塑形的角度对准分支血管，再从导管中将导丝导入分支血管以完成分支血管通路的建立，之后沿导丝将分支支架植入相应的分支血管。
针对这种建立分支血管通路的方法，主体覆膜支架的开窗需要与分支血管对准，否则分支血管的开口部分被主体覆膜支架覆盖，导致导管和导丝导入分支血管的难度增大，延长手术时间。
发明内容
本发明的目的在于提供一种医用装置，其可以用于涉及主动脉弓病变的微创伤介入治疗，可有效降低导丝导入分支血管的难度，有利于分支血管通路的建立，并缩短手术时间。
为实现上述目的，本发明提供了一种医用装置，包括：覆膜支架、导管和束缚件，其中所述覆膜支架上设有窗口；所述导管用于部分地设置在所述覆膜支架内部；所述束缚件用于向所述覆膜支架施加径向挤压力，以使所述覆膜支架沿径向收缩至压缩态；且所述医用装置被配置为当所述覆膜支架处于所述压缩态时，所述窗口的位置与所述导管的远端端部的位置相对应；所述远端是指所述医用装置在使用过程中首先进入患者体内的一端。
可选地，所述覆膜支架还被配置为向所述导管施加压力，并使所述覆膜支架与所述导管保持相对静止。
可选地，所述导管的远端端部穿过所述窗口并伸出所述覆膜支架。
可选地，所述导管包括主体节段和远端节段，所述远端节段成角度地连接于所述主体节段的远端；所述主体节段部分地设置于所述覆膜支架内，所述远端节段穿过所述窗口并伸出所述覆膜支架。
可选地，所述主体节段的轴线与所述覆膜支架的轴线平行。
可选地，所述主体节段的轴线与所述远端节段的轴线形成一钝角，所述钝角的角度为150°～180°。
可选地，所述医用装置还包括定位件，所述定位件的近端与所述导管的远端连接，所述定位件的远端被所述束缚件束缚于所述覆膜支架的外表面上。
可选地，所述定位件与所述导管分体成型，并连接于一体；或者，所述定位件与所述导管为一体式结构。
可选地，所述导管的远端外表面上设有显影元件。
可选地，所述医用装置还包括内衬，所述内衬用于穿设在所述导管内。
可选地，所述医用装置还包括输送器，所述输送器包括内管，所述覆膜支架套装在所述内管上，且所述导管用于设置在所述内管与所述覆膜支架之间。
可选地，所述导管还与所述内管连接。
与现有技术相比，本发明的医用装置具有如下优点：前述的医用装置包括覆膜支架、导管和束缚件；所述覆膜支架上设有窗口；所述导管用于部分地设置在所述覆膜支架内部；所述束缚件用于向所述覆膜支架施加径向挤压力，以使所述覆膜支架沿径向收缩至压缩态；所述医用装置被配置为当所述覆膜支架处于所述压缩态时，所述窗口的位置与所述导管的远端端部的位置相对应，所述远端是指所述医用装置在使用过程中首先进入患者体内的一端。并进一步优选所述覆膜支架向所述导管施加压力，以使所述覆膜支架与所述导管保持相对静止。如此，所述覆膜支架和所述导管可同步地输送至主动脉内，且使用者可在释放所述覆膜支架之前沿所述导管将导丝导入主动脉并穿过所述覆膜支架上的窗口导入分支血管，简化导管和导丝导入分支血管的操作，也避免因覆膜支架释放且窗口未对准分支血管导致的超选困难，有利于分支血管通路的建立，并缩短手术时间。

另外，以下说明内容的各个实施例分别具有一或多个技术特征，然此并不意味着使用本发明者必需同时实施任一实施例中的所有技术特征，或仅能分开实施不同实施例中的一部或全部技术特征。换句话说，在实施为可能的前提下，本领域技术人员可依据本发明的公开内容，并视设计规范或实作需求，选择性地实施任一实施例中部分或全部的技术特征，或者选择性地实施多个实施例中部分或全部的技术特征的组合，借此增加本发明实施时的 弹性。
如在本说明书中所使用的，单数形式“一”、“一个”以及“该”包括复数对象，复数形式“多个”包括两个以上的对象，除非内容另外明确指出外。如在本说明书中所使用的，术语“或”通常是以包括“和/或”的含义而进行使用的，除非内容另外明确指出外，以及术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接。可以是机械连接，也可以是电连接。可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通或两个元件的相互作用关系。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本发明中的具体含义。
在本文中，术语“近端”、“远端”是从使用该医疗器械的医生角度来看相对于彼此的元件或动作的相对方位、相对位置、方向，尽管“近端”、“远端”并非是限制性的，但是“近端”通常指该医疗设备在正常操作过程中靠近医生的一端，而“远端”通常是指首先进入患者体内的一端。这里的患者可以是人，也可以是其他动物。
本发明的核心思想在于提供一种医用装置，所述医用装置包括覆膜支架、导管、以及束缚件。其中，所述覆膜支架上设有窗口，所述导管用于部分地设置于所述覆膜支架内部。所述束缚件用于向所述覆膜支架施加径向挤压力，以使所述覆膜支架沿径向收缩至压缩态。当所述医用装置处于所述压缩态时，所述窗口的位置与所述导管的远端端部的位置相对应。所述医用装置可用于涉及主动脉弓处的病变的治疗，所述导管可随所述覆膜支架一起输送至主动脉弓处，且在释放所述覆膜支架之前，当所述覆膜支架上的窗口位于一分支血管附近时，使用者通过所述导管向主动脉弓导入导丝，进而所述导丝可导入分支血管，避免现有技术中释放所述覆膜支架之后执行导管和导丝导入分支血管时发生覆膜支架的窗口与分支血管未对准，导致分支血管开口至少部分被遮挡的问题。优选地，所述覆膜支架还向所述导管施加压力，并使所述覆膜支架与所述导管保持相对静止，避免所述覆膜支架与所述导管之间发生移位造成所述导管的远端端部错开所述窗口。
为使本发明的目的、优点和特征更加清楚，以下结合附图对本发明作进一步详细说明。需说明的是，附图均采用非常简化的形式且均使用非精准的比例，仅用以方便、明晰地辅助说明本发明实施例的目的。附图中相同或相似的附图标记代表相同或相似的部件。
图1是本发明实施例一所提供的医用装置的结构示意图。请参考图1，所述医用装置100包括覆膜支架110、导管120和束缚件130。其中，所述覆膜支架110上设有窗口111。 所述导管120用于部分地设置在所述覆膜支架110的内部。所述束缚件130用于向所述覆膜支架110施加径向挤压力，以使所述覆膜支架110沿径向收缩至压缩态。所述医用装置100被配置为当所述覆膜支架110处于所述压缩态时，所述窗口111的位置与所述导管120的远端端部的位置相对应。本领域技术人员应知晓，所述导管120具有轴向贯通的内腔，所述导管120的远端端部即为所述内腔的远端开口，因此，这里所述导管120的远端端部的位置与所述窗口111的位置相对应，是指所述导管120的远端端部在所述覆膜支架110的轴向及周向上均与所述窗口111的位置相对应，以使所述覆膜支架110不覆盖所述导管120的内腔的远端开口。所述导管120的远端即是指所述导管120的首先进入患者体内的一端。所述覆膜支架110可以为自膨式支架，所述导管120的材质可以为高分子材料例如PA12或Pebax7233等。
所述医用装置100可用于涉及主动脉弓病变的治疗。实际工作时，所述覆膜支架110在所述束缚件130的作用下处于压缩状态并连同所述导管120一起安装于一输送器(图中未示出)上，所述输送器用于将所述覆膜支架110及所述导管120一并输送至患者的主动脉弓处，并使所述窗口111位于一分支血管附近。如图3及图4所示，由于所述导管120的远端与所述窗口111对应设置，因此在释放所述覆膜支架110之前，使用者可将一导丝200通过所述导管120的内腔输送至主动脉弓并从所述导管120的远端伸出，进而导入分支血管。这样做的优点在于，所述覆膜支架110及所述导管120一次性地输送至体内，避免二次输送，且还避免出现所述覆膜支架110释放后与分支血管未对准导致导管120导入分支血管困难，进而避免导丝200导入分支血管困难的问题，有利建立分支血管通路并缩短手术时间。较佳地，所述覆膜支架110还向所述导管120施加压力，并使所述覆膜支架110与所述导管120保持相对静止，以避免所述覆膜支架110与所述导管120的相对位置发生改变进而造成所述导管120的远端端部与所述窗口111错开。
可选地，所述医用装置100还包括所述输送器，所述输送器包括内管和外管。所述覆膜支架110套装在所述内管上，所述外管套装在所述内管外部并还用于覆盖所述覆膜支架110。
优选地，请返回参考图1并结合图2，所述导管120的远端外表面上设有显影元件140，方便使用者判断所述导管120的远端以及所述窗口111的位置。
优选地，请继续参考图1及图2，所述导管120的远端端部穿过所述窗口111并伸出 所述覆膜支架110。具体地，所述导管120可包括主体节段121和远端节段122，较佳地，所述远端节段122成角度地连接有所述主体节段121的远端。所述主体节段121部分地设置在所述覆膜支架110中，所述远端节段122穿过所述窗口111并伸出所述覆膜支架110，也即，所述远端节段122的远离所述主体节段121的一端部即为所述导管120的远端端部。这样做，更方便所述导丝200导入分支血管。本实施例中，所述主体节段121的轴线与所述远端节段122的轴线之间形成一钝角θ，所述钝角θ的角度优选为150°～180°，且所述主体节段121的轴线可与所述覆膜支架110的轴线平行。
接下去介绍所述医用装置的使用方法：首先组装所述医用装置100。具体过程为：先将所述覆膜支架110套装在所述输送器的内管上，并将所述导管120部分地穿设在所述覆膜支架110中。具体地，所述导管120的所述主体节段121的近端位于所述覆膜支架110的外部并延伸至所述输送器的近端，所述主体节段121的远端位于所述覆膜支架110与所述内管之间，而所述导管120的所述远端节段122从所述窗口111处伸出所述覆膜支架110。再利用所述束缚件130束缚所述覆膜支架110，本实施例中，所述束缚件130可以是现有技术中任意一种绑扎线圈，只要其能够使所述覆膜支架110径向收缩并固定在所述内管上即可。也即，所述束缚件130可以在所述覆膜支架110的外部向所述覆膜支架110施加径向挤压力，以使所述覆膜支架110压缩并固定在所述内管上。可选地，所述覆膜支架110在所述束缚件130的作用下还能够向所述导管120施加压力，并使所述覆膜支架110与所述导管120在所述压力的作用下保持相对静止。替代性地，在实践中，也可以利用其他方式例如绑扎或胶粘以使所述导管120与所述内管连接，以将所述导管120固定在所述覆膜支架110与所述内管之间，并使所述导管120与所述覆膜支架110保持相对静止。最后，将所述外管覆盖在所述覆膜支架110的外部。
接着，按照常规方法将所述覆膜支架110连同所述导管120输送至患者的主动脉弓处，并回撤所述外管，以使所述覆膜支架110露出。
接着，调整所述覆膜支架110的位置，以使所述窗口111处于一分支血管附近，并使所述导管120的远端对准分支血管(如图3所示)。
接着，将一导丝200沿所述导管120的内腔输送至患者体内，所述导丝200从所述内腔的远端伸出并直接导入分支血管(如图4所示)。
随后，解除所述束缚件130对所述覆膜支架110的束缚，释放所述覆膜支架110。至 此，分支血管的通路建立完成，使用者可继续向分支血管导入分支支架。
图5是本发明实施例二所提供的医用装置的结构示意图，请参考图5，本实施例与实施例一的区别之处在于，所述医用装置100还包括定位件150，所述定位件150的近端与所述导管120的远端连接，所述定位件150的远端被所述束缚件130束缚于所述覆膜支架110的外表面上。这样做，可确保所述导管120与所述覆膜支架110保持相对静止，避免所述导管120在输送过程中移位导致其远端端部偏离所述窗口111。可以理解的是，所述定位件150的近端不宜连接于所述导管120远离所述覆膜支架110的中心轴线的一侧，避免对所述导丝200造成干扰，有利于所述导丝200导入分支血管。优选地，所述定位件150的近端连接于所述导管120靠近所述覆膜支架110的中心轴线的一侧。
本实施例中，所述定位件150可以与所述导管120分体成型后再连接，所述定位件150可以是金属丝或高分子丝。
图6及图7是本发明实施例三所提供的医用装置的局部结构示意图。如图6及图7所示，本实施例与实施例二的区别之处在于，所述定位件150与所述导管120为一体式结构。具体来说，所述定位件150和所述导管120由同一根管材制作而成，所述管材包括轴向连接的第一部分和第二部分，所述第一部分的远离所述覆膜支架110的中心轴线的部分管壁被切除，所述第一部分剩余的靠近所述覆膜支架110的中心轴线的部分管壁形成所述定位件150，所述定位件150可覆盖所述管材的1/4-1/2的圆周面。所述第二部分构成所述导管120。
进一步地，所述第二部分的部分管壁也被切除，以使所述导管120的远端端面形成一斜面123，并使所述斜面123与所述定位件150平滑过渡地连接，减小所述导管120与所述定位件150连接处的应力，还可增大所述导管120的内腔的远端开口，方便调整所述导丝200的方向。
本发明实施例四所提供的医用装置与实施例一的区别之处在于，所述医用装置100还包括内衬(图中未示出)，所述内衬用于穿设在所述导管120的内腔中。该内衬在组装所述医用装置100以及将所述覆膜支架110输送至患者体内的过程中使用，当所述覆膜支架110定位完成之后，该内衬撤出，其作用是避免所述导管120的所述内腔被所述覆膜支架110压闭，以及防止所述导管120在所述覆膜支架110内扭转时造成的打折变形。
所述内衬的材料可以为高分子例如Pebax7233、PTFE、PA12等，其外径小于或等于 所述导管120的内径。
虽然本发明披露如上，但并不局限于此。本领域的技术人员可以对本发明进行各种改动和变型而不脱离本发明的精神和范围。这样，倘若本发明的这些修改和变型属于本发明权利要求及其等同技术的范围之内，则本发明也意图包含这些改动和变型在内。
