具体实施方式
现在将参考附图详细描述本发明所公开的用于便于将套管针组件与适配器组件组装的实施例，在附图中，类似附图标号表示若干视图中的每个视图中的相同或对应元件。如本领域中常见的，术语“近侧”指代较接近用户或操作员(即，外科医生或临床医生)的那一部分或部件，而术语“远侧”指代距离用户较远的那一部分或部件。
首先参考图1，适合与本公开的装置和方法一起使用的适配器组件(大体上示出为适配器组件20)为手术吻合器械10的部件。所述吻合器械10另外包括动力手柄组件30、装载单元40和砧座组件50。尽管参考手术吻合器械10和适配器组件20示出和描述，但是本公开的方面可修改用于与具有替代配置手术吻合器械一起使用。对于示例性动力手术吻合器械的详细描述，请参考共同拥有的美国专利第9,023,014号(“'014专利”)和美国专利第9,055,943号(“'943专利”)，所述专利中的每个的内容以全文引用的方式并入本文中。
手术吻合器械10的适配器组件20将仅在完整公开本公开的方面所需要的程度上加以描述。对于详细描述示例性适配器组件，请参考共同拥有的美国专利公开第2016/0106406号(“'406公开”)和第2017/0086879号(“'879公开”)，所述公开的内容以全文引用的方式并入本文中。
另外参考图2，手术吻合器械10的适配器组件20包括被配置用于可操作连接到手柄组件30(图1)的近侧部分22和被配置用于可操作连接到装载单元40(图1)的远侧部分24。尽管被示出和描述为形成集成单元，但是据设想，适配器组件20的近侧和远侧部分22、24可形成为彼此可释放地固定的分开的单元。适配器组件20的远侧部分24包括用于将装载单元40与适配器组件20可释放地连接的连接构件26。如下面进一步详细描述，连接器构件26限定用于容纳套管针加载装置100的对准特征116的对准狭槽27。
被配置用于与本公开的装置和方法一起使用的可拆卸套管针组件(大体上示出为套管针组件50)可释放地固定在适配器组件20的远侧部分24内。将仅在完全公开本公开的方面所必需的程度上描述套管针组件50。对于示例性套管针组件的详细论述，请参考'879公开。
可拆卸套管针组件50包括壳体52、可滑动地安置在壳体52内的套管针构件54，和可操作地容纳在套管针构件54内的驱动构件56(图3)，用于相对于壳体52轴向移动套管针构件54。套管针构件54的锥形远侧部分54a被配置用于通过手术吻合器械10(图1)的砧座组件50(图1)可释放连接。套管针构件54的主体部分54b限定接合狭槽55。如下文将进一步详细描述，接合狭槽55容纳套管针装载装置100的接合臂104(图3和4)的凸缘146(图4)。
现在参考图3-8，用于保持套管针组件50并且将其与根据本公开的实施例的适配器组件20对准的装置大体上示出为套管针装载装置100。套管针装载装置100包括基座构件102和通过螺钉106固定到基座构件102的接合臂104。基座构件102被配置成容纳套管针组件50的近侧部分并且将套管针组件50与适配器组件20的远侧部分24(图2)对准，如下文所描述。套管针装载装置100的接合臂104被配置成将套管针组件50与套管针装载装置100的基座构件102对准并且将套管针组件50与基座构件110可释放地固定，如下文所描述。
继续参考图3-8，套管针装载装置100的基座构件102包括被配置成便于套管针装载装置100与适配器组件20对准的连接器部分110、被配置成容纳套管针组件50的容纳部分120，和被配置用于由用户可操作接合的手柄部分130。尽管示出为集成形成，但是连接器部分110、容纳部分120和手柄部分130中的任何一个或全部可形成为使用已知方法固定在一起的分开的部件。
套管针装载装置100的基座构件102的连接器部分110包括第一圆柱形区段112和第二圆柱形区段114。基座构件102的连接器部分110的第一圆柱形区段112被配置成容纳在适配器组件20的远侧部分24的连接器构件26内。第一圆柱形区段112包括容纳在适配器组件20的连接器构件26中的狭槽27内的对准特征116，以将套管针装载装置100与适配器组件20对准。基座构件102的连接器部分110的第二圆柱形区段114充当止动构件，用于防止基座构件102的连接器部分110的第一圆柱形区段114过度插入适配器组件100的连接器构件26(图2)中。
套管针装载装置100的基座构件102的容纳部分120包括具有波形区段124和锥形区段126的细长主体122。细长主体122的波形区段124被配置成便于当在套管针组件50被固定到适配器组件20(图2)之后套管针装载装置100与套管针组件50分开时由套管针装载装置100的用户接合。如下文所描述，细长主体122的锥形区段126适应在套管针组件50与套管针装载装置100附接和分开期间套管针装载装置100的接合臂104的挠曲。
基座构件102的细长主体122限定被配置成容纳套管针组件50的套管针构件54的纵向通道121。细长主体122的开口远侧末端便于套管针组件50在固定到套管针装载装置100时清洁和灭菌。基座构件102的细长主体122还限定用于适应接合臂104的凸缘140的切口123a和用于容纳接合臂104的锁定部分144的狭槽123b。在实施例中，并且如图所示，基座构件102的细长主体122限定用于容纳用于将接合臂104固定到基座构件102的螺钉106的带螺纹开口125。
在实施例中，细长主体122包括用于允许在套管针装载装置100固定到套管针组件50时套管针组件50清洁和灭菌的冲洗端口127。
尽管示出为从基座构件102的容纳部分120径向向外延伸的基本上平面主体132，但是基座构件102的手柄部分130可包括便于由用户处置的任何配置。基座构件102的平面主体132使得其中套管针组件20固定到其上的套管针装载装置100能够维持直立站立位置以适应在处置期间和在与适配器组件20组装之前放置套管针组件50，而没有污染和/或损害套管针组件50的无菌的风险。
套管针装载装置100的接合臂104包括细长部分140、安置在细长部分140的第一末端上的C形凸缘部分142，和从凸缘部分142延伸的锁定部分144。释放突片146从凸缘部分142延伸。接合臂104可由单件材料集成形成。在实施例中，接合臂104由冲压金属片或模制塑料形成。
在实施例中，并且如图所示，套管针装载装置100的接合臂104通过螺钉106固定到基座构件102，所述螺钉106通过在接合臂104的细长部分140的第二末端中形成的开口141容纳。接合臂104被配置成使得当细长部分140固定到基座构件102时，接合臂104的凸缘部分142容纳在基座构件102的切口123a内，并且接合臂104的锁定部分144容纳在基座构件102中的狭槽123b内。基座构件102的锥形区段126允许接合臂104挠曲以如由图7中的箭头“A”指示将接合臂104的锁定部分144移出基座构件102中的狭槽123a。
接合臂104的锁定部分144包括倾斜表面144a，以便于将套管针组件50收纳在基座构件102的容纳部分120内。更具体地，在套管针组件50被套管针装载装置100的基座构件102的纵向通道121容纳以引起接合臂104向内挠曲时，套管针装载装置100的接合臂104的倾斜表面144a接合套管针组件50。以此方式，接合臂104的锁定部分144从套管针装载装置100的基座构件102中的狭槽123a内移动，以允许将套管针组件50收纳在套管针装载装置100的基座构件102内。
现在参考图7和8，通过将套管针构件54容纳在基座构件102的纵向通道121中并且将在套管针构件54中的狭槽55与在基座构件102中的切口125对准，以允许接合臂104的接合部分144收纳到在套管针构件54中的狭槽55中，套管针组件50固定到套管针装载装置100。在套管针组件50容纳在纵向通道121内时，接合部分144的倾斜表面144a接合套管针构件54，以引起套管针装载装置100的接合臂102如由图7中的箭头“A”指示挠曲，以允许套管针组件50收纳在基座构件102内。一旦在套管针构件54中的狭槽55与接合臂104的接合部分144对准，接合臂104就返回到其非挠曲位置(图8)，并且接合部分144通过在基座构件102中的狭槽127和通过在套管针构件54中的狭槽55容纳，以将套管针组件50固定在基座构件102的纵向通道121内。
转到图9和10，一旦套管针装载装置100固定到套管针组件50，套管针装载装置100就可用于将套管针组件50固定到适配器组件20。通过将套管针装载装置100的基座构件102的连接器部分110的第一圆柱形区段112容纳在适配器组件20的连接器构件26内，套管针组件20固定到适配器组件20。当在第一圆柱形区段112上的对准特征116容纳在连接器构件26的对准狭槽27内时，确保套管针组件50与适配器组件20的正确对准。如上文所提到，基座构件102的连接器部分110的第二圆柱形部分114充当止动件，以防止套管针组件50过度插入适配器组件20内。在实施例中，适配器组件20可提供套管针组件50固定到适配器组件20的听觉或触觉指示。
一旦套管针组件50固定到适配器组件20，套管针装载装置100就通过接合突片部分146以从在套管针组件50的套管针构件54中的狭槽55内移动突起部分144，并且然后远离适配器组件20和套管针组件50周围纵向滑动套管针装载装置100，通过首先挠曲接合臂104与适配器组件20和套管针组件50分开。
在将套管针组件50固定在适配器组件20内之后，适配器组件20的操作基本上类似于在'879公开中示出和描述的示例性适配器组件的操作，所示公开先前以全文引用的方式并入本文中。
现在参考图12-19，用于保持和对准套管针组件50的装置的另一个实施例大体上示出为套管针装载装置200。套管针装载装置200基本上类似于上文所描述的套管针装载装置100，并且因此将仅详细描述它们之间所涉及的差异。
套管针装载装置200包括基座构件202、容纳在基座构件202周围的接合构件204，和固定到接合构件204的保持构件206。如下文将描述，弹簧构件208将基座构件202偏置远离保持构件206，以将套管针组件50弹簧承载在套管针装载装置200内。
套管针装载装置200的基座构件202包括被配置成便于套管针装载装置200与适配器组件20(图2)对准的带凸缘的近侧部分210和被配置成容纳套管针组件50的容纳部分220。更具体地，容纳部分220包括具有锥形区段226的细长主体222。在套管针组件50与套管针装载装置200附接和分离期间，锥形区段226适应套管针装载装置200的接合构件204的挠曲。基座构件202的容纳部分220的细长主体222限定被配置成容纳套管针组件50的套管针构件54(图12)的纵向通道221。基座构件202的细长主体222还限定用于适应接合构件204的凸缘242的切口223a和用于容纳接合构件204的锁定部分244的狭槽223b。
第一和第二组突起212、214从基座构件202的容纳部分220的细长主体222向外延伸。第一和第二组突起212、214限定在它们之间的槽213。如下文将描述，槽213被配置成以滑动方式容纳接合构件204的导引臂248。
在实施例中，细长主体222包括用于允许在套管针装载装置200固定到套管针组件50时套管针组件50清洁和灭菌的冲洗端口227(图15)。
套管针装载装置200的接合构件204包括细长部分240、安置在细长部分240的第一末端上的C形凸缘部分242，和从凸缘部分242延伸的锁定部分244。接合构件204另外包括用于将接合构件204相对于基座构件202固定的导引臂248。导引臂248从接合构件204的连接器部分250延伸。连接器部分250限定用于容纳用于将接合构件204连接到保持构件206的螺钉206a的开口249。
套管针装载装置200的接合构件204被配置成使得当接合构件204固定在基座构件202周围时，接合构件204的凸缘部分242容纳在基座构件202的切口223a内，并且接合构件204的锁定部分244容基座构件202中的狭槽223b纳在内。基座构件202的锥形区段226允许接合构件204挠曲，以将接合构件204的锁定部分244移出在基座构件202中的狭槽223a。
接合构件204的锁定部分244包括倾斜表面244a，以便于将套管针组件50的套管针构件54(图12)收纳在基座构件202的容纳部分220内。
接合构件204的导引臂248各自包括用于在基座构件202的容纳部分220的细长主体222上分别接合第一组突起212的柄脚252。
如上文所提到，接合构件204通过螺钉206a固定到保持构件206，所述螺钉206a通过在接合构件204的连接器部分250中的开口249容纳。基座构件202通过导引臂248相对于接合构件204固定。更具体地，接合构件204容纳在基座构件202周围，其中导引臂248容纳在分别限定在基座构件202的第一和第二突起212、214之间的槽213内。在导引臂248上的柄脚252相对于基座构件202保持接合构件204。套管针装载装置200的弹簧208容纳在接合构件204的连接器部分250和基座构件202之间，以相对于保持构件206偏置基座构件202。
套管针装载装置200以与上文所描述的套管针装载装置100基本上相似的方式操作。当套管针组件50未正确地通过套管针装载装置200的接合构件204固定时，当将套管针组件50容纳在套管针装载装置200的基座构件202的纵向通道221内时，由定位在基座构件202和保持构件206之间的弹簧208产生的偏置引起套管针组件从基座构件202的纵向通道221内弹出。
现在参考图18和19，关于套管针组件350和适配器组件320(图19)，示出用于确保套管针组件正确地容纳和固定在适配器组件内的机构。
首先参考图18，套管针组件350包括外壳体352和套管针构件354。外壳体352限定被配置成用于适应压缩弹簧360的环形切口353。切口353的深度，和/或压缩弹簧360的厚度使压缩弹簧360的一部分安置在外壳体352的外表面352a的径向外侧。
现在参考图19，适配器组件320被配置成可释放地容纳套管针组件350。一旦套管针组件350完全安放在适配器组件320内，锁定机构(未示出)将套管针组件350固定在适配器组件320内。
应变机构330安置在适配器组件320内，并且被配置成当套管针组件320容纳在适配器组件320内时接合压缩弹簧360。更具体地，在套管针组件350收纳在适配器组件320内期间，和在套管针组件350完全安放在适配器组件320内之前，例如接合锁定机构(未示出)，压缩弹簧360开始接触应变机构330。套管针组件350继续插入适配器组件320内压缩压缩弹簧360，例如对其施加载荷。
在套管针组件350未正确地安放在适配器组件320内和/或锁定机构(未示出)未正确地接合套管针组件350的情况下，压缩弹簧360的装载引起套管针组件350从适配器组件320弹出。
在吻合程序之后，套管针组件350可通过以传统方式从锁定机构释放套管针组件350从适配器组件320弹出。
现在参考图20-22关于套管针组件450和适配器组件420，示出用于保证在适配器组件内的套管针组件的对准的机构。
套管针组件450包括壳体452和轴承壳体456。壳体452和轴承壳体456中的每个分别包括展平的部分452a、456a。各个壳体452和轴承壳体456的展平的部分452a、256a键连到保持器壳体470(图20)的展平的部分470a和轭壳体480(图21)的展平的部分480a。
特别参考图20，保持器壳体470限定用于容纳套管针组件450的纵向通道471。各个壳体452和轴承壳体456的展平的部分452a、456a与保持器壳体470的展平的部分470a彼此对准，以确保套管针组件450在保持器壳体470内正确定向。类似地，各个壳体452和轴承壳体456的展平的部分452a、456a与保持器壳体470的展平的部分470a的未对准防止套管针组件450装载在保持器壳体470内。
特别参考图21，轭壳体480限定用于容纳套管针组件450的纵向通道481。轴承壳体456的展平的部分456a与保持器壳体480的展平的部分480a彼此对准，以确保套管针组件450在轭壳体480内正确定向。类似地，轴承壳体456的展平的部分456a与轭壳体480的展平的部分480a的未对准防止套管针组件450装载在轭壳体480内。
在实施例中，各个壳体452、轴承壳体456、保持器壳体470、轭壳体480的展平的部分452a、456a、470a、480a可由金属形成。当展平的部分452a、456a和展平的部分470a、480a未对准时，介接展平的部分452a、456a、470a、480a的金属结构为组装适配器组件420的人员(例如外科医生)提供更大的反馈，并且/或者增加迫使套管针组件450在适配器组件420内的难度。
本公开的实施例可单独使用或与实施例结合使用，以便于套管针组件在适配器组件内的正确装载和重新装载。
尽管本文已经参考附图描述本公开的说明性实施例，但是应理解，本公开不限于那些确切的实施例，且本领域技术人员可在其中在不脱离本公开的范围或精神的情况下进行各种其它改变和修改。
