在本说明书中，术语“近端”通常用于指装置的更靠近临床医生的部分，而术语“远端”通常用于指装置的更远离临床医生的部分。此外，术语“内窥镜”通常用于指内窥镜、腹腔镜、关节镜和/或通过小直径切口或套管进行的任何其它手术。此外，术语“临床医生”通常用于指医务人员，包括医生、护士和辅助人员。
图1和图2绘示了圆形钉合装置10，包括本发明公开的重新装载组件的示范性实施例，所述重新装载组件通常显示为重新装载组件100。钉合装置10包括手柄组件12、细长主体或适配器组件14、重新装载组件100和砧座组件18，砧座组件18支撑用于在如本领域已知的间隔位置和近似位置之间相对于重新装载组件100移动。重新装载组件100包括近端部分102，近端部分102可释放地联接到细长主体16的远端部分16a。手柄组件12包括固定把手20，固定把手20用于支撑致动按钮22，以控制钉合装置10的各种功能的操作，包括分别接近重新装载组件100和砧座组件18，从重新装载组件100击发缝合钉，以及切割组织或取芯组织。
钉合装置10绘示为包括电动手柄组件12的电动钉合装置，电动手柄组件12可以支撑一个或多个电池(未示出)。细长主体14呈适配器组件的形式，所述适配器组件将动力从手柄组件12分别传递到重新装载组件100和砧座组件18。电动钉合装置的实例可以在美国专利第9,055,943号('943专利)、第9,023,014号('014专利)以及美国公开第2018/0125495号和第2017/0340351号中找到，其全部内容通过引用并入本文。
参照图2和图3，重新装载组件100包括外壳壳体110、支撑多个缝合钉“S”的钉仓120、缝合钉推动器组件130以及支撑环形刀具132的刀架140。钉仓120是环形的，并且限定钉凹座121的环形排。每个钉凹座121支撑多个缝合钉“S”中的一个(图3)。
重新装载组件100的推动器组件130包括缝合钉推动构件132和环形推动器134，缝合钉推动构件132和环形推动器134一起限定纵向通孔131(图4)。环形推动器134具有邻接缝合钉推动构件132的近端部分的远端部分，使得环形推动器134在外壳壳体110内的远端移动导致缝合钉推动构件132在外壳壳体110内的远端移动。重新装载组件100的缝合钉推动构件132具有多个指状件136。多个指状件136中的每一个被容纳在钉仓120相应的一个钉凹座121内，并且可移动通过相应的钉凹座121，以在缝合钉推动构件132在外壳壳体110内从缩回位置移动到前进位置时将缝合钉“S”从钉凹座121中弹出。
重新装载组件100的外壳壳体110包括外壳体部分112和与外壳体部分112间隔开的内壳体部分114，以限定环形空腔113。推动器组件130和刀架140(包括环形刀具142)可在环形空腔113内在缩回位置(图10)与前进位置(图14)之间移动。推动器组件130可独立于刀架140从其缩回位置移动到其前进位置(图11)，以将缝合钉“S”从钉仓120中弹出。
环形刀具142支撑在刀架140的外表面周围，并限定圆柱空腔141。在实施例中，环形刀具142包括突起142a(图10)，突起142a被容纳在刀架140上的开口141a中，以将环形刀具142固定在刀架140周围。可选地，可以使用其它紧固技术将刀具142固定到刀架140。
此外参照图4，刀架140包括一对柔性臂144，所述一对柔性臂144沿着刀架140的近端部分140a延伸。柔性臂144的端部包括钩部分146。如下面将进一步详细描述的，钩部分146配置成选择性地与重新装载组件100的电可编程只读存储器保持器170接合，以防止刀架140过早前进，并在击发之后将刀架140保持在缩回位置。尽管显示为包括一对柔性臂144，但是设想刀架140可以仅包括一个臂，或者可以包括多于两个臂。
继续参照图2和图3，外壳壳体110包括支撑联接机构150的近端部分110a，联接机构150可用以将重新装载组件100联接到钉合装置10的适配器组件14(图1)。联接机构150包括保持构件152和联接构件154。联接构件154被容纳在外壳壳体110的近端部分110a周围，并且配置成与适配器组件14的远端接合以将重新装载组件100联接到适配器组件14。在实施例中，保持构件152包括突起156，突起156被容纳在外壳壳体110的近端部分110a中的开口113(图3)中，以将保持构件152和联接构件154固定到外壳壳体110。可以设想，可以使用其它联接机构将重新装载组件100固定到适配器14。
参照图5和图6，外壳壳体110的内壳体部分114限定通孔115(图5)，通孔115容纳砧座组件18(图1)的砧座轴(未示出)。对于砧座组件的更详细描述，请参见例如'106专利。通孔115容纳衬套160，衬套160限定与通孔115同轴的通孔161。在实施例中，衬套160由高强度材料(例如，金属)形成，以向外壳壳体110的内壳体部分114提供增加的强度。
此外参照图7，重新装载组件100包括电可编程只读存储器保持器170，电可编程只读存储器保持器170被容纳在轴衬160上并支撑在外壳壳体110内。电可编程只读存储器保持器170包括壳体部分172和从壳体部分172延伸出去的环形凸缘部分174。壳体部分172限定用于容纳电可编程只读存储器芯片(未示出)的空腔171(图5)。如本领域已知的，电可编程只读存储器芯片与适配器组件14(图1)连通，以向适配器组件14和手柄组件12提供与重新装载组件10的特性相关的信息。如下面将进一步详细描述的，壳体部分172进一步限定一对开口173，所述一对开口173用于容纳刀架142的柔性臂144的钩部分146(图8)。电可编程只读存储器保持器的环形凸缘部分174配置成被容纳在衬套160周围。
参照图8至图10，推动器组件130的缝合钉推动器构件132和刀架140中的每一个分别限定切口133(图8)、143(图9)，当相应的推动器组件130和刀架140处于其缩回位置(图10)时，切口133、143容置电可编程只读存储器保持器170。
特别参照图10，当推动器组件130和刀架140处于其缩回位置时，刀架140的柔性臂144的钩部分146被容纳在电可编程只读存储器保持器170的壳体部分172中的开口173内。柔性臂144的钩部分146与电可编程只读存储器保持器170的壳体部分172的接合将刀架140维持在其缩回位置。
转到图11，推动器组件130的缝合钉推动器构件132包括锥形内表面138，当缝合钉推动器构件132在外壳壳体110内向远端移动第一距离，如箭头“A”所示，到达部分前进位置时，锥形内表面138与刀架140的柔性臂144上的倾斜外表面148接合。当缝合钉推动器构件132向远端移动时，通过推动器组件130的缝合钉推动器构件132的锥形内表面138与刀架140的柔性臂144的倾斜外表面148的接合使得柔性臂144如箭头“B”所示径向向内弯曲。柔性臂144的向内弯曲使柔性臂144的钩部分146从电可编程只读存储器保持器170的壳体部分172中的开口173内缩回，并且与壳体部分172脱离接合。
参照图12，在刀架140的柔性臂144不再与电可编程只读存储器保持器170接合的情况下，刀架140前进第二距离，如箭头“C”所示，到达部分前进位置，以从电可编程只读存储器保持器170的壳体部分172内收回柔性臂144的钩部分146。
转到图13，推动器组件130的缝合钉推动器构件132接着前进第三距离，如箭头“D”所示，到达完全前进位置，以使推动器组件130的环形推动器134前进并从钉仓120内弹出缝合钉“S”(图3)。尽管显示为将推动器组件130移动第一距离以释放刀架140并且接着移动第二距离以从钉仓120弹出缝合钉“S”的多步骤过程，但是设想了缝合钉推动器构件132可以配置成同时地或在同一行程内释放刀架140和弹出缝合钉“S”。
参照图14，在推动器组件130的第二次前进之后或同时，刀架140前进第四距离，如箭头“E”所示，以将环形刀具144移动到完全前进位置，并使得切开容纳在钉仓120与砧座组件18的头部组件18a之间的组织(未示出)。
转到图15，在切开过程之后，刀架140缩回，如箭头“F”所示。当刀架140缩回时，刀架140的柔性臂144的钩部分146的成角度表面146a与电可编程只读存储器保持器170的壳体部分172接合，以引起柔性臂144向内弯曲，如箭头“G”所示。
如图16所示，刀架140的连续缩回，如箭头“H”所示，使得柔性臂144的钩部分146被容纳在电可编程只读存储器保持器170的壳体部分172中的开口173内，以使刀架140的柔性臂144与电可编程只读存储器保持器170的壳体部分172重新接合。一旦刀架140与电可编程只读存储器保持器170重新接合，就防止刀架140和环形刀具142随后前进。
在完成钉合过程之后，临床医生可能想要从环形刀具142内移除组织环形圈。当临床医生抓住组织环形圈并向远端拉动组织环形圈以将组织环形圈从外壳壳体110中拉出时，刀架的柔性臂144与电可编程只读存储器保持器170的壳体部分172之间的接合会防止刀架140和环形刀具142向远端移动以将环形刀具142保持在外壳壳体110内凹进的位置。
本领域技术人员将理解，在本文具体描述并在附图中示出的装置和方法是非限制性的示范性实施例。可以设想，结合一个示范性实施例说明或描述的元件和特征可以与另一个的元件和特征组合，而不脱离本发明的范围。同样，本领域技术人员将基于上述实施例了解本发明的其它特征和优点。因此，本发明不受特别示出和描述的内容限制，而是由所附权利要求限定。
