Description

夹持器械与夹持组件
本申请要求2019年8月28日递交的发明名称为“夹持器械及夹持组件”的申请号CN201910804053.1的在先申请优先权，上述在先申请的内容以引入的方式并入本文本中。
技术领域
本申请实施例涉及医疗器械领域，尤指一种心脏瓣膜瓣环的夹持器械及夹持组件。
背景技术
三尖瓣位于右房室口，常见发病为三尖瓣关闭不全，即收缩期血流从右心室返流入右心房，造成右心房高度扩大，压力升高，静脉血液回流障碍。由于右心室负荷增加，代偿而肥厚，容易发生右心衰竭。
三尖瓣反流一般由肺动脉高压，右室扩大，三尖瓣瓣环扩张引起，临床上常以三尖瓣反流的病因(左心衰，肺动脉高压等)的表现为常见，出现三尖瓣反流后，乏力，腹水，水肿，肝区疼痛，消化不良，纳差等右心衰症状加重。三尖瓣轻度反流并无明显的临床症状，但当严重反流时即需要手术治疗。
传统治疗手段包括药物治疗，和有相对应手术指征的外科手术方法。其中，外科手术方法还包括瓣膜置换术和瓣膜修补术。在外科手术方法中，典型的开胸、开心手术侵入性过大，需要建立体外循环，具有较高的并发症发生率和感染风险。患者很多耐受不了巨大的外科风险而只能无奈等待死亡。
目前微创经导管治疗三尖瓣返流的产品已有数款在临床应用，但均在实验阶段，未实现成熟的应用，而且各自的技术均有局限。
有鉴于此，如何克服现有技术中存在的种种局限，即为本申请待解决的技术问题。

具体实施方式
为了使本领域的人员更好地理解本申请实施例中的技术方案，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本申请实施例一部分实施例，而不是全部的实施例。基于本申请实施例中的实施例，本领域普通技术人员所获得的所有其他实施例，都应当属于本申请实施例保护的范围。
于本文说明书中，所谓“远端”是指远离操作者的夹持器械(作动杆)的一端，所谓“近端”是指接近操作者的夹持器械(作动杆)的一端。
本申请主要提供一种夹持器械及夹持组件，可用于夹持人体组织5的预设部位51(参考图)，于本实施例中，人体组织5例如为心脏瓣膜瓣环，具体而言，本申请所提供的夹持装置1属于一种经导管介入治疗三尖瓣反流的产品设计，该设计类似于外科的Kay’S手术方法，通过将三尖瓣的后瓣两端缝合起来，使三尖瓣二瓣化，使得瓣环的整体周长缩短，从而实现使三尖瓣反流减小的目的。
请配合参阅图1A、图1B、图2A、图2B及图3，其为显示本申请的第一实施例的夹持器械1的示意图。如图所示，本申请的夹持器械1主要包括定位基座11、移动基座12、多个夹持臂13、多个连动臂14、以及作动杆15。
定位基座11中形成有第一穿设通道110，移动基座12中形成有第二穿设通道120。
各夹持臂13的一端分别连接至移动基座12，以提供各夹持臂13相对于 移动基座12转动而处于展开位置或夹持位置。于本实施例中，夹持臂13的设置数量为至少两个，在下文中，将以本申请附图所示的两个夹持臂13A和13B进行说明，但并不以此为限，夹持臂13的设置数量可实际使用需求而增加至三个或更多，合先叙明。
各连动臂14的两端分别连接定位基座11和各夹持臂13，以供各夹持臂13间接连接定位基座11。于本实施例中，连动臂14的设置数量可以与夹持臂13相对应，即如图所示的连动臂14A和14B，以提供夹持臂13A,13B分别经由连动臂14A,14B而与定位基座11间接连接，从而提供夹持臂13A,13B可随着定位基座11与移动基座12之间的距离变化而产生连动效应(请容后详述)，然并不以此为限，于其他实施例中，连动臂14的设置数量大于夹持臂13的数量，例如，可针对两个夹持臂13设置多个连动臂14。
作动杆15分别穿设于第一穿设通道110与第二穿设通道120中，以供定位基座11与移动基座12共轴装配于作动杆15上，于本实施例中，定位基座11可相对于作动杆15周向转动但轴向固定，而移动基座12可在相对于作动杆15进行周向转动的同时还可相对于作动杆15进行轴向移动。
于实际操作时，可通过令作动杆15周向转动，使得共轴装配于作动杆15上的移动基座12与定位基座11之间的距离产生变化，而令夹持臂13A,13b随之产生连动以相对于移动基座12转动而处于展开位置(如图1A及图2A所示)或夹持位置(如图1B及图2B所示)。其中，当夹持臂13A,13B相对于移动基座12分别处于各自的展开位置时，可分别定位于人体组织5的预设部位51上；而当夹持臂13A,13B相对于移动基座12分别处于各自的夹持位置时，可借由夹持臂13A与夹持臂13B之间的协同配合而夹持人体组织2的预设部位51于二者之间(参考图6A及图6B)。
于本实施例中，当作动杆15沿第一方向(例如顺时针方向)周向转动时，定位基座11和移动基座12同时相对于作动杆15周向转动，使得作动杆15在进行周向转动时，定位基座11与移动基座12之间始终保持周向固定，且于此状态下，定位基座11相对于作动杆15轴向固定，而移动基座12 则相对于作动杆15轴向向上移动(即朝接近于定位基座11的方向移动)，使得共轴装配于作动杆15上的移动基座12与定位基座11之间的距离逐渐缩小，于此状态下，夹持臂13A和13B将相对于移动基座12由图1A及图2A所示展开位置逐渐转动至如图1B及图2B所示的夹持位置。反之，当作动杆15沿相反于第一方向的第二方向(例如逆时针方向)周向转动时，定位基座11相对于作动杆15轴向固定，而移动基座12则相对于作动杆15轴向向下移动(即朝远离定位基座11的方向移动)，使得共轴装配于作动杆15上的移动基座12与定位基座11之间的距离逐渐增加，于此状态下，夹持臂13A和13B将相对于移动基座12由图1B及图2B所示夹持位置逐渐转动至如图1A及图2A所示的展开位置。
于一实施例中，移动基座12的设置位置相较于定位基座11的设置位置更靠近于作动杆15的远端，即在图2A和图2B所示的图示中，移动基座12设置在定位基座11下方的位置，此结构设计的好处在于，可令夹持臂13A,13B之间所形成的容纳空间不受干涉，以提高对于人体组织的夹持效果，并避免对夹持于夹持臂13A,13B之间的人体组织造成影响。然并不以为限，亦可视实际使用需求，而将定位基座11设置在作动杆15上更靠近远端的位置，即在图2A和图2B所示的图示中，定位基座11设置在移动基座12下方的位置，使得定位基座11容纳于夹持臂13A,13B之间所形成的容纳空间内部。
于另一实施例中，在移动基座12的设置位置相较于定位基座11的设置位置更靠近于作动杆15的远端的情况下，在作动杆15上对应设置所述移动基座的位置上还设置有第一调节单元151，同时，在移动基座12上设置有第二调节单元121，其中，第一调节单元151与第二调节单元121为结构适配，以提供移动基座12相对于作动杆15进行周向转动的同时还可进行轴向移动。于本实施例中，第一调节单元151例如为形成在作动杆15上的外螺纹，第二调节单元121则例如为形成在移动基座12的第二穿设通道120内的内螺纹。上述结构设计的好处在于，可通过精细化地控制作动杆15的周向转动的幅度，而精确调节夹持臂13A,13B的转动幅度，进而提供夹持臂13A,13B之间 高精准度的夹持力。
于另一实施例中，夹持器械1还包括有限位结构16，其用于定义移动基座12相对于作动杆15进行轴向移动的最大移动范围。如图4A及图4B所示，于本实施例中，限位结构16为分设于夹持臂13A，13B的近端(即夹持臂13A,13B上用于连接移动基座12的一端)的限位单元16A,16B。如图所示，设置于夹持臂13A的近端的限位单元16A上具有第一展开限位面161A和第一夹持限位面162A，设置于夹持臂13B的近端的限位单元16B上具有第二展开限位面161B和第二夹持限位面162B，其中，第一展开限位面161A和第二展开限位面161B协同配合用于限定夹持臂13A和13B之间的最大展开幅度(如图4A所示)，第一夹持限位面162A和第二夹持限位面162B协同配合用于限定夹持臂13A和13B之间的最小收缩幅度(如图4B所示)。需说明的是，限位机构16的设计并不以上述为限，其他结构亦可适用于本申请。
此外，于又一实施例中，夹持器械1还包括有定位结构17，其设置在作动杆15与定位基座11之间，用于当作动杆15在进行周向转动时，限制作动杆15相对于定位基座11发生轴向移动。如图3所示，于本实施例中，定位机构17包括套设在作动杆15上并位于定位基座11的相对两侧的卡簧17A和防松垫片17B，其中，卡簧17A用于限制定位基座11相对于作动杆15朝作动杆15的近端方向发生轴向移动，防松垫片17B则用于限制定位基座11相对于作动杆15朝作动杆15的远端方向发生轴向移动。需说明的是，定位结构17的设计并不以上述的卡簧17A和防松垫片17B为限，也可采用其他元件或结构设计予以实现。
另外，于实际操作时，夹持器械1可通过外接输送装置4，以通过输送装置4施加作用力，而驱动夹持器械1的夹持臂13A和13B执行作动。于本实施例中，输送装置4主要包括有输送件41和驱动件42，其中，输送件41连接至夹持器械1的定位基座11，用于限制定位基座11周向转动，驱动件42连接至夹持器械1的作动杆15，用于对作动杆15施加作动力，以驱动作动杆15沿第一方向(例如顺时针方向)或第二方向(例如逆时针方向)进行 周向转动。
于本申请中，输送装置4与夹持器械1的连接方式可以有多种，例如，如图7A及图7B所示，于本实施例中，输送件41与驱动件42可分别在作动杆15的近端与定位基座11与作动杆15连接。如图8A及图8B所示，于另一实施例中，输送装置4的输送件41与驱动件42也可分别在作动杆15的远端连接定位基座11与作动杆15。如图9A及图9B所示，于又一实施例中，输送装置4的输送件41与驱动件42还可分别在作动杆15的相对两端连接定位基座11与作动杆15，例如，输送件41在作动杆15的近端连接定位基座11，而驱动件42在作动杆15的远端连接作动杆15。
另外，本申请还提供了第二实施例的夹持器械，其与上述第一实施例的夹持器械1的主要区别在于，夹持臂和连动臂的连接设置与第一实施例正好相反，亦即，各夹持臂的一端分别连接定位基座，而各连动臂的两端分别连接移动基座与各夹持臂，以供各夹持臂通过各连动臂而间接连接移动基座，以提供各夹持臂随着移动基座与定位基座之间的距离产生变化产生连动以相对于移动基座进行转动。除此之外，本实施例的其他结构设计原理均与上述第一实施例所述的夹持器械1相似，在此不予赘述。
请继续参阅图5A至图5C以及图6A及图6B，本申请的另一实施例还提供一种夹持组件2，其包括辅助支撑件3和夹持器械1，其中，辅助支撑件3用于对人体组织5(人体瓣膜瓣环)的预设部位51提供辅助支撑，以使人体组织5的预设部位51呈凸起状态。夹持器械1则用于夹持呈凸起状态的预设部位51以及辅助支撑件3，于本实施例中，夹持器械1的主要结构如上述各实施例中所详述，在此不予赘述。
于本实施例中，辅助支撑件3可通过各种实施样式予以实现，具体而言，辅助支撑件3可例如为顶珠结构(图5A所示)，或例如为自攻簧丝结构(如图5B所示)，亦或者是拉网结构(如图5C所示)。
请继续参考图6A及图6B，于本实施例中，以辅助支撑件3为拉网结构为例，其中，人体组织5的预设部位51包括有相对设置的第一侧511与第 二侧512，如图所示，辅助支撑件3用于在预设部位51的第一侧511抵顶预设部位51，而夹持器械1则用于在预设部位51的第二侧512夹持呈凸起状态的预设部位51以及辅助支撑件3，以使预设部位51被夹设于辅助支撑件3与夹持器械1之间，从而形成类似三明治的夹持状态，借此，可以有效防止人体组织5被撕裂，同时还可以提升夹持的固定效果。
综上所述，本申请所提供的夹持器械与夹持组件适用于通过微创方法治疗三尖瓣反流症，具有结构简单、夹持牢固，不易滑脱，以及防止人体组织被撕裂的优点。
再者，利用作动杆相对于定位基座和移动基座进行周向旋转，以使定位基座与移动基座之间的距离产生变化而驱动夹持臂转动的技术原理对人体组织进行夹持，可以达到精确控制夹持臂的转动幅度的技术效果，从而提供高精准度的夹持力。
最后应说明的是：以上实施例仅用以说明本申请实施例的技术方案，而非对其限制；尽管参照前述实施例对本申请进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例技术方案的精神和范围。
