图1和2示出圆形缝合装置10，其包含通常展示为重新装载组件100的本发明所公开的重新装载组件的示范性实施例。缝合装置10包含手柄组件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，所述砧座组件经过支撑以用于相对于重新装载组件100在间隔开的位置与合拢位置之间移动，如本领域中已知。重新装载组合件100包含近端部分102(图1)，其以可拆卸方式连接到细长主体14的远端部分14a。手柄组件12包含固定把手22，其支撑用于控制缝合装置10的各种功能的操作的致动按钮24，所述操作包含分别从重新装载组件100击发缝钉和切割组织或取出组织的核心的重新装载组件100和砧座组件18的接近。
缝合装置10被示出为电力驱动缝合装置，其包含可支持一个或多个电池(未展示)是电力驱动手柄组件12。细长主体14呈适配器组件的形式，其将功率从手柄组件12分别转移到重新装载组件100和砧座组件18。可在美国专利第9,055,943号('943专利)、第9,023,014号('014专利)和美国公开第2018/0125495号和第2017/0340351号中发现电力驱动缝合装置的实例，所述专利和公开以全文引用的方式并入本文中。替代地，可预见的是，本公开还可并入到例如美国专利第7,303,106号('106专利)中所教示的手动地提供动力的缝合装置或配置成与不包含手柄组件的机器人系统一起使用的缝合装置中。举例来说，所述细长主体可适于以与本领域中已知的其它机器人仪器类似的方式接合机器人手术系统。'106专利还以全文引用的方式并入本文中。
参看图2和3，重新装载组件100包含外壳壳体110、推进器组件112(图8)、刀架114、支撑在刀架114上的环形刀116、钉仓118，和支撑于钉仓118内的多个缝钉120。钉仓118为环形的并限定钉凹座124的环形行。钉凹座124中的每一个支撑多个缝钉120中的一个。推进器组件112包含环形推进器128(图3)和在一起限定纵向通孔132的缝钉推进构件130。推进器128具有紧靠缝钉推进构件130的近端部分的远端部分，使得推进器128在外壳壳体110内的远侧移动引起缝钉推进构件130的远侧移动。重新装载件100的缝钉推进构件130具有多个指形件134。多个指形件134中的每一个收纳在钉仓118的钉凹座124中的相应一个钉凹座内，且可移动通过相应的钉凹座124以当缝钉推进构件130从缩回位置移动到外壳壳体110内的前进位置时从钉凹座124弹出缝钉120。
外壳壳体110包含外壳体部分140和内壳体部分142，其彼此间隔开以在内壳体部分142与外壳体部分140之间限定环形空腔144。推进器组件112(图8)、刀架114和环形刀116可在缩回位置与前进位置之间在环形空腔144内移动。推进器组件112可独立于刀架114和环形刀116从其缩回位置移动到其前进位置，以从钉仓118弹出缝钉120。环形刀116支撑在刀架114的外表面周围，且限定圆柱形空腔117和远侧切割边缘117a。在实施例中，刀116包含突出部116a(图8)，其收纳在刀架114中的开口117c(图8)中以将刀116紧固在刀架114周围。替代地，其它紧固技术可用于将刀116紧固到刀架114。在推进器组件112从其缩回位置移动到其前进位置之后，刀架114可从其缩回位置移动到其前进位置以切割定位在钉仓118的径向内侧的组织。
外壳壳体110的内壳体部分142限定通孔150(图3)，其收纳砧座组件18的砧座轴18a(图1)。对于示范性砧座组件18的更详细描述，参见例如'106专利。通孔150具有收纳衬套152的近端部分，所述衬套限定通孔150a，所述通孔150a是同轴的并形成内壳体部分142的通孔150的延伸。在实施例中，衬套152由例如金属的高强度材料形成，以将增加的强度提供到外壳壳体110的内壳体部分142。
外壳壳体110包含支撑联接机构160(图2)的近端部分158(图3)，所述联接机构可用于以可拆卸方式将重新装载组件100联接到缝合装置10(图1)的适配器组件14以促进替换重新装载组件100和重新使用缝合装置10。联接机构160包含保持构件162和联接构件164。联接构件164收纳在外壳壳体110的近端部分158(图3)周围，且配置成接合适配器组件14的远端部分114a以将适配器组件14联接到重新装载组件100。可预见，其它联接机构可用于将重新装载组件100紧固到适配器14。
重新装载组件100可包含支撑在外壳壳体110上的可擦除可编程只读存储器170(图3)。如本领域中已知，可擦除可编程只读存储器可与适配器组件14通信以向适配器组件14和手柄组件12提供与重新装载组件10的特性有关的信息。
参看图3到5，刀架114在推进组件112的缩回位置与前进位置之间可移动地定位在推进组件112的通孔132(图8)内并限定阶梯式中心孔172。阶梯式中心孔172包含小直径近端部分172a和较大直径远端部分172b。刀架114的中心孔172的近端部分172a收纳外壳壳体110的内壳体部分142(图8)，使得刀架114围绕内壳体部分142滑动。
刀架114限定环形肩部176(图5)，其定位于中心孔172的近端部分172a与远端部分172b之间。中心孔172的近端部分172a由纵向延伸的主体部分173(图4)限定，所述纵向延伸的主体部分通过纵向槽孔178彼此分离。纵向槽孔178收纳外壳壳体110的引导部分179(图6)以在刀架114在其前进位置与缩回位置之间移动时将所述刀架限制为外壳壳体110的环形空腔144内的纵向移动。肩部176支撑弹性锁定构件180，其沿着刀架114(图4)的邻近纵向狭槽178中的一个的外表面延伸，如下文进一步详细描述。
在实施例中，锁定构件180包含细长弹簧臂，其基本为U形且具有第一和第二支腿180a及在支腿180a之间延伸的后跨部180b。当锁定构件180紧固到刀架114时，后跨部180b横跨刀架114的纵向槽孔178中的一个(图4)延伸。锁定构件180由例如弹簧钢的弹性材料形成，并支撑在刀架114的肩部176的外表面上以沿着刀架114的近端部分延伸。在实施例中，锁定构件180的支腿180a延伸通过限定在刀架114的环形肩部176中的开口182(图4)，且包含弯曲端部“B”(图5)以将锁定构件180紧固到刀架114。可预见，刀架114可支撑一个或多个锁定构件180，例如，1个、2个、3个等。
参看图6到8，外壳壳体110的内壳体部分142包含卡扣构件154，其定位于分别在内壳体部分142与外壳体部分140之间的环形空腔144中。卡扣构件154包含悬臂钩部分154a，所述悬臂钩部分在刀架142处于其缩回位置中且锁定构件154处于未偏置状态时延伸到刀架114的相应纵向狭槽178(图8)中并接合锁定构件180的后跨部180b，如下文详细地论述。卡扣构件154包含凸轮表面190，所述凸轮表面在锁定构件180处于与钩部分154a脱离的偏置状态(图8)时定位在钩部分154a径向外侧并支撑锁定构件180。当刀架114在重新装载组件100被击发之前处于缩回位置中时，锁定构件180处于偏置状态。卡扣构件154的钩部分154a包含面192，所述面朝向外壳壳体110的内壳体部分142在近侧方向上径向向内渐缩。
参看图8，当刀架114在重新装载组件100的击发之前处于缩回位置中时，锁定构件180的后跨部180a支撑在卡扣构件154的凸轮表面190上。在此位置中，锁定构件180处于偏置状态并从卡扣构件154的钩部分154a径向向外挠曲。
参看图9，当缝合装置10通过手柄组件12(图1)的致动而致动以击发缝钉120(图8)时，包含环形推进器128的推进器组件112和缝钉推进构件130在由箭头“A”指示的方向上朝向砧座组件18前进以在夹持在钉仓118与砧座18之间的组织中形成缝钉120。
在缝钉被击发之后，重新装载组件100的刀架114在由箭头“B”指示的方向上前进以使环形刀116在由箭头“C”指示的方向上前进。当刀架114和环形刀116前进时，联接到刀架114的外表面的锁定构件180的后跨部180b沿着卡扣构件154的凸轮表面190向远侧滑动并滑动离开。当后跨部180b离开凸轮表面190到在卡扣构件154远侧的位置时，锁定构件154返回到未偏置状态，其中后跨部180b与卡扣构件154的钩部分154a的渐缩面192轴向对准。当刀架114在外壳壳体110的环形空腔144内前进时，环形刀116前进到砧座组件118中以切割夹持在砧座组件18与钉仓118之间的组织。
参看图10和11，当刀架114在由箭头“D”指示的方向上在外壳壳体110的环形空腔144内向近侧移动到其缩回位置时，环形刀116撤回到外壳壳体110中且切割边缘117a由钉仓118遮蔽。当刀架114接近其缩回位置时，在由图11中的箭头“D”指示的方向上移动的锁定构件180的后跨部180b接合卡扣构件154的渐缩面192并使卡扣构件154在由箭头“E”指示的方向上向上偏置，使得后跨部180b在卡扣构件154下方经过而到达卡扣构件154的钩部分154a的止动表面194后方的位置。在此位置中，锁定构件180与卡扣构件154之间的接合阻挡刀架114和刀116朝向前进位置向后移动。因而，环形刀116在外壳壳体110内保持在其缩回位置中，以便于临床医生操纵和安置重新装载组件。
图13到19示出本发明所公开的重新装载组件200(图17)的替代实施例。重新装载组件200类似于重新装载组件100，除了修改了卡扣构件154(图10)和锁定构件180(图3)的配置以外。重新装载组件200的所有剩余的部件如关于重新装载组件100所描述。因此，将在本文中仅详细地描述修改。
参看图13和14，锁定构件280呈扭力弹簧的形式并包含间隔开的支腿280a和后跨部280b。支腿280a中的每一个的中心部分限定环282。环282收纳枢转构件284，其支撑在肋部286之间，所述肋部形成于刀架214的外表面上。如上文关于锁定构件180所论述，锁定构件280支撑在刀架214的外表面上，使得锁定构件280的后跨部280b横跨限定在刀架214的纵向主体部分273之间的纵向狭槽278中的一个延伸。
参看图15和16，外壳壳体210的内壳体部分242包含卡扣构件254，其定位于分别在内壳体部分242与外壳体部分240之间的环形空腔244中。卡扣构件254包含钩部分254a，其延伸通过刀架214中的相应纵向狭槽278，到达在刀架114径向外侧的位置。卡扣构件254在刀架242处于缩回位置中时接合锁定构件280的后跨部280b，并且卡扣构件254处于如下文详细地论述的未偏置状态以阻挡刀架214前进。卡扣构件254还包含凸轮构件290，其定位在卡扣构件254的钩部分254a的径向外侧。当刀架214在重新装载组件200被击发之前处于缩回位置中时，凸轮构件290以偏置状态将锁定构件280支撑在卡扣构件254的钩部分254a外侧。卡扣构件254的钩部分254a包含渐缩表面292，其定位在纵向狭槽278内且在近侧方向上径向向外渐缩。卡扣构件254的钩部分254a和凸轮构件290限定凹座296。
参看图17，当刀架214在重新装载组件200的击发之前处于缩回位置中时，锁定构件280的后跨部280b支撑在卡扣构件254的凸轮构件290上。在此位置中，锁定构件280处于偏置状态并且在卡扣构件254的钩部分254a径向外侧挠曲，使得锁定构件280的后跨部280b定位在凹座296外部。
参看图18，当缝合装置10(图1)通过手柄组件12的致动而致动以击发缝钉220(图17)时，包含环形推进器228的推进器组件212和缝钉推进构件230在由箭头“G”指示的方向上朝向砧座组件18前进以在夹持在钉仓218与砧座18之间的组织中形成缝钉220。
在缝钉被击发之后，重新装载组件200的刀架214在由箭头“H”指示的方向上前进以使环形刀216在由箭头“I”指示的方向上前进。当刀架214和环形刀216前进时，围绕枢转构件284联接到刀架214的外表面的锁定构件280的后跨部280b沿着卡扣构件254的凸轮表面290向远侧滑动并且滑动离开。当后跨部280b离开凸轮构件290到在卡扣构件254远侧的位置时，锁定构件280返回到未偏置状态，其中后跨部280b与卡扣构件254的钩部分254a的渐缩表面292轴向对准。当刀架214在外壳壳体210的环形空腔244内前进时，环形刀216前进到砧座组件18中以切割夹持在砧座组件18与钉仓218之间的组织。
参看图19，当刀架214在由箭头“J”指示的方向上在外壳壳体210的环形空腔244内向近侧移动到其缩回位置时，环形刀216在由箭头“K”指示的方向上撤回到外壳壳体210中且刀216的切割边缘217a由钉仓218遮蔽。当刀架214接近其缩回位置时，锁定构件280的后跨部280b接合卡扣构件254的钩部分254a的渐缩表面292并且沿着渐缩表面192且在钩部分254a上方向外偏置。当后跨部280b向近侧越过钩部分254a时，后跨部280b向内扣接到凹部296中到达卡扣构件254的钩部分254a的止动表面294后方的位置。在此位置中，锁定构件280与卡扣构件254之间的接合阻挡刀架214和刀216朝向前进位置向后移动。因而，环形刀216在外壳壳体210内保持在其缩回位置中，以便于临床医生操纵和安置重新装载组件200。
