具体实施方式
现在将参照附图详细描述包括锁定机构的当前公开的手术吻合装置的实施例，其中，相同的附图标记指代几幅视图的每一视图中的相同或对应的元件。在本说明书中，术语“近侧”通常用于指装置的较靠近临床医生的部分，而术语“远侧”通常用于指装置的较远离临床医生的部分。
图1和图1A示出了总体作为100示出的当前公开的手术吻合装置的实施例。手术吻合装置100包括手柄组件102、主体部104、以及工具组件106。手柄组件102包括固定手柄102a、活动手柄102b、收缩构件107a以及关节式运动构件107b。在实施例中，工具组件106形成可替换的再装载器108的一部分，可替换的再装载器108还包括支撑工具组件106的近侧的再装载器主体部110。再装载器108将会在下文中进一步详细论述。选择地，工具组件106可以直接支撑在主体部104的远侧端。
参照图1A和图2，可替换的再装载器108包括工具组件106、近侧主体部110、中间安装组件112、驱动构件130以及发射锁定组件200，这些将在下文中进一步详细地描述。安装组件112被固定到工具组件106并且被枢转地联接到再装载器108的近侧主体部110，从而将工具组件106枢转地固定到近侧主体部110。再装载器108在公布号为2013/0098965(“‘965公布”)的美国公布中有大致的描述，除了发射锁定机构已经改变。公布号为2013/0098965的美国公布通过引用其全部而并入此。因此，再装载器108的与在‘965号公布中公开的共同的部件在此将简要地描述，并且新的发射锁定机构200及其操作方法将在此详细地描述。
工具组件106包括在非接近位置与接近位置之间能相对于彼此移动的砧座组件114和钉仓组件116。砧座组件114包括砧座主体120以及被固定到砧座主体120的下侧从而限定通道126(图6)的砧座板122。如将在下文中进一步详细论述的，砧座板122限定多个吻合钉容纳凹处122a(图6)以及纵向狭槽124，该纵向狭槽124被定尺寸为可滑动地容纳可替换的再装载器108的驱动构件130的工作端210的一部分。砧座主体120的近侧端包括悬臂132，该悬臂132限定用于容纳安装组件112的圆柱状枢转构件112a的孔132a。
钉仓组件116包括支撑板136、钉仓主体138、多个吻合钉、以及包括滑块148并将在下文中进一步论述的吻合钉发射组件。钉仓组件116能容纳在沟槽134或者通道组件中。通过如已经以引用的形式并入此处的‘965公布中描述的搭扣配合，将钉仓主体138和支撑板136附接到沟槽134。可以构想其他形式的连接并且可以替代搭扣配合使用，或者附加到其使用。通过延伸穿过在砧座主体120和沟槽134中形成的开口139a的枢转构件139，沟槽134或者通道组件枢转地固定到砧座主体120。钉仓主体138限定多个横向间隔的吻合钉固持狭槽140，该狭槽140以与在钉仓主体138的组织接触表面142中的吻合钉形成凹处122对准的方式定位。每一狭槽140被构造为容纳紧固件或者吻合钉144以及推进器146。致动滑块148定位在钉仓主体138内，从而在纵向上穿过钉仓主体138进入与推进器146的接合，进而从钉仓主体138顺序地弹射吻合钉144。对于包括支撑板136的钉仓组件116的更多详细的论述，参见已经以引用的方式并入此处的‘965公布。
再参照图3至图5，安装组件112包括由柱销153或者铆钉固定在一起的上安装部150以及下安装部152。安装部150和152中的每一个均分别包括枢转构件112a和112b。如上所述，枢转构件112a被容纳在砧座主体120的悬臂132(图2)的孔132a内，从而将上安装部150固定到砧座主体120。第一联接构件156a(图2)具有第一端以及第二端，该第一端限定也容纳枢转构件112a的开口158a，该第二端容纳在凹槽113a内，其中该凹槽113a限定在可替换的再装载器108的近侧主体部110中。枢转构件112b被支撑在下安装部152上并且被容纳在第二联接构件156b的开口158b中。第二联接构件156b被容纳在与限定在近侧主体部152中的凹槽113a类似的凹槽内，从而将下安装部152枢转地固定到再装载器108的近侧主体部110。枢转构件139延伸穿过形成在砧座主体120和沟槽134中的开口139a，并且容纳在形成于下安装部152的开口160中来将下安装部152固定到沟槽134。
再次参照图2，再装载器108的近侧主体部110包括包含在外套筒184内的上壳体半部180以及下壳体半部182。当外套筒184绕上壳体半部180和下壳体半部182被定位时，第一联接构件156a和第二联接构件156b被固持在凹槽113a内，从而防止工具组件106与再装载器108的近侧主体部110的分离。上壳体半部180和/或下壳体半部182的近侧端包括接合凸起物186，该接合凸起物186用于以卡扣式联接布置的方式可释放地接合吻合装置100的主体部104的远侧端。壳体半部180和182限定用于可滑动地容纳驱动构件130的通道190。关节式运动连接件192被定尺寸为：可滑动地定位在上壳体半部180和下壳体半部182之间，并且适于接合手术吻合装置100的关节式运动机构(未示出)。一对熄灭(blow out)板组件196邻近壳体半部180和182的远侧端定位，从而防止驱动构件130在吻合装置100的工具组件106的关节式运动和发射过程中向外变弯和凸出。希里卡(Scirica)等人的专利号为7,143,924的美国专利(“‘924专利”)提供了近侧主体部110的部件的更详细的论述，该专利的全部内容通过引用其全部合并于此。
再参照图4至图7，驱动构件130包括主体和具有刀具212的工作端210。工作端210包括上凸缘216a、下凸缘216b以及将上凸缘216a和下凸缘216b相互连接的竖直支杆214。刀具212被支撑在工作端210的竖直支杆214上或者形成在工作端210的竖直支杆214中。上凸缘216a被定位成可滑动地容纳在砧座组件114的通道126(图6)内，以及下凸缘216b被定位成沿沟槽134的外表面127可滑动地定位。在使用中，驱动构件130向远侧的移动最初将上凸缘216a推进到形成在砧座板122上的凸轮面280a，并且将下凸缘216b推进到与形成在沟槽134上的凸轮面280b接合，从而将钉仓组件116朝向砧座组件114枢转到关闭或者接近位置。推进随着工作端210移动穿过工具组件106，驱动构件130的继续的推进逐渐保持邻近工作端210的最小的组织间隙。
在某些实施例中，驱动构件130的主体由如不锈钢的材料的多个成叠薄板130a-d形成。锁紧构件202围绕再装载器108的近侧端支撑，从而防止驱动构件的轴向的移动，直到再装载器108附接到吻合装置100。‘924专利详细描述了可替换的再装载器108的上述部件的更详细的论述，该‘924专利的全部内容通过引用合并于此。
驱动构件130的主体的远侧端支撑工作端210并且限定止动表面222。滑块148布置在钉仓组件116内的工作端210远侧的位置处。当工作端210处于其最近侧位置并且工具组件106处于打开或者非接近位置(图6)时，滑块和工作端处于它们各自的初始位置。滑块148包括定位为与推进器146接合的多个凸轮面228(图3)，该推进器146定位在钉仓组件116内，当滑块148被推进穿过工具组件106时，该推进器146弹射来自钉仓主体136的吻合钉144。滑块148的近侧端包括一个或者多个指状部229，该指状部229限定将在下文中进一步详细论述的开口230或者狭槽(图4)。
发射锁定组件200包括枢转地支撑在下安装部152的远侧端的闩锁构件242。闩锁构件242包括U形主体(图4A)，该U形主体具有近侧基体构件244和两个间隔开的向远侧延伸的支腿246。基体构件244可以设置有阻止构件244a，该阻止构件244a限定阻止表面并且可以被焊接或者固定到基体构件244，从而提供对基体构件244的附加的支撑。可选择地，基体构件244的近侧端可以限定阻止表面。闩锁构件242从第一位置枢转到第二位置。在第一位置，闩锁构件242的阻止构件244a与驱动构件130的止动表面222对准，从而防止驱动构件130在工具组件106内推进，而在第二位置，阻止构件244a与驱动构件130的止动表面222未对准，从而许可驱动构件130在工具组件106内推进。
参照图3至图6，闩锁构件242的每个支腿246具有位于中心的枢转构件250以及邻接表面252。枢转构件250被支撑在安装组件112的下安装部152的钩状臂256上，从而将闩锁构件242枢转地支撑在下安装部152上。偏置构件设置成将闩锁构件242朝向第一位置推动。在某些实施例中，偏置构件包括一对弹簧260，该一对弹簧260绕各自的柱销262被支撑，该柱销262固定到下安装部152的远侧面。每个弹簧260被定位为与闩锁构件242的相应的邻接表面252接合，从而如图6所示，使闩锁构件242沿逆时针方向偏置。每个支腿246的远侧端包括向下延伸的凸起266，该凸起266被定位为：当滑块148处于收缩位置、闩锁构件242处于第一位置以及砧座组件114和钉仓组件116处于接近位置(图7A)时，延伸穿过限定在滑块148中的开口230。
参照图3和图4，弹簧290绕在沟槽134内的每个圆柱292布置。每个圆柱292被固定到沟槽134的内表面从而为弹簧290提供对准以及稳定性。每个弹簧290被定位在沟槽134的内表面和限定在下安装部152的底部表面的相应的盲孔294(图4)之间，从而将工具组件106向非接近位置推动。其他的偏置构件或者特征件可以替代弹簧使用。
参照图6和图7，当驱动构件130处于完全收缩位置并且工具组件106处于非接近或者打开位置时，驱动构件130的工作端210的上凸缘216a和下凸缘216b对于滑块148向近侧间隔开，并且对于形成在相应的砧座板122和沟槽134上的凸轮面280a和280b向近侧地间隔开。在工具组件106的非接近位置，闩锁构件242通过弹簧260朝向逆时针位置推动。下安装部152包括表面298，该表面298被定位为接合基体构件244或者阻止构件244a。在阻止构件244a与下安装部152的表面298之间的接合防止闩锁构件242的进一步的逆时针的旋转，从而将闩锁构件242固持在第一位置。
参照图7A至图7B，当驱动构件130通过致动活动手柄102b(图1)而向远侧推进时，工作端210的上凸缘216a和下凸缘216b接合凸轮面280a和280b，并且将钉仓组件116朝向砧座组件114枢转，从而使工具组件106向接近位置移动。当工具组件106处于接近位置时，闩锁构件242固持在第一位置，以便闩锁构件242的支腿246的向下延伸的凸起266延伸穿过滑块148的开口230，且接合沟槽134的内表面。在第一位置，阻止构件244a与在驱动构件130的主体的远侧端上的止动表面222对准，但是间隔开。驱动构件130的工作端210也对于滑块148的主要部分向近侧定位。
参照图8和图9，当活动手柄102a被致动来发射吻合装置100并且弹射来自钉仓组件116的钉仓主体136的吻合钉144时，驱动构件130被推进从而使驱动构件130的工作端210移动穿过工具组件106进入与滑块148的接合，从而将滑块148向远侧推进穿过工具组件106。随着滑块148向远侧移动穿过工具组件106，部分地限定开口230的滑块148的近侧指状部229接合锁定构件242的向下延伸的凸起266，从而如图9所示，使闩锁构件242克服弹簧260的偏置而沿顺时针方向绕闩锁构件242的枢转构件250枢转。随着闩锁构件242沿顺时针方向朝向第二位置枢转，阻止构件244a向下地枢转出与止动表面222的对准。
如图10至图11B所示，驱动构件130的继续推进实现滑块148的继续的推进。随着滑块148被推进，致动滑块148的指状部229将闩锁构件242固持在第二位置，以使驱动构件130的基部130a穿过阻止构件244a。驱动构件130的基部130a将闩锁构件242固持在阻止构件244a定位在驱动构件130的止动表面222以下的第二位置。
参照图12和图13，当吻合装置100已被发射并且驱动构件130返回到收缩位置时，处于与驱动构件130的邻接关系的致动滑块148保持在钉仓主体138的远侧端。在驱动构件130的基部130a移动到闩锁构件242的近侧位置后，闩锁构件242通过弹簧260返回到第一位置。在驱动构件130的收缩位置，闩锁构件242通过偏置弹簧260返回到第一位置，以便阻止构件244a被定位为与驱动构件130的止动表面222对准，从而防止驱动构件130的再推进。而且，工作端具有沿近侧方向面向的并且位于竖直支杆上的成角度的凸轮面，该凸轮面能够使闩锁件朝向第一位置推动。
如在图12中示出的，由于滑块148处于其推进位置，因此滑块148的指状部229对于闩锁构件242的向下延伸的凸起266向远侧定位。因此，驱动构件130的再推进不会实现锁定构件242从第一位置向第二位置的枢转，并且防止了驱动构件130的再推进。
为了再使用吻合装置100，驱动构件130必须完全地收缩并且钉仓组件必须被替换。更具体地，钉仓组件从沟槽134拆卸并且新的钉仓组件被定位在沟槽134内。新的钉仓组件具有被定位的滑块148，从而使滑块148的推进引起指状部229再次接合闩锁构件242并且使闩锁构件242从第一位置枢转到第二位置，从而允许驱动构件被推进。
本领域技术人员将会理解的是，在此具体描述的以及在附图中示出的装置和方法是非限定的代表性的实施例。可以预想，结合一个代表性的实施例示出或描述的元件和特征可以结合另一个元件和特征，而不脱离本公开的范围。而且，本领域的技术人员基于上述实施例将会意识到本公开的进一步的特征和优点。因此，除了如所附的权利要求书所指示的，否则，本公开没有被具体示出的和描述的内容所限制。
