参见图3和4，安装组合件170包含上部安装部分172和下部安装部分174以及保持刀片176。如图示，上部安装部分172和下部安装部分174通过从上部安装部分172延伸的柱178而紧固在一起。上部安装部分172和下部安装部分174中的每一者分别包含枢轴部件172a(图3)和174a(图4)。如上文所述，上部安装部分172上的枢轴部件172a接纳于砧主体132的支架132a的孔133(图3)内，以将上部安装部分172紧固到砧主体132。近端主体部分102的第一耦合部件114a(图3)具有第二末端，其界定也接纳枢轴部件172a的开口115a。下部安装部分174上的枢轴部件174a接纳于近端主体部分102的第二耦合部件114b(图3)的开口115b中。将砧主体132紧固到夹爪部件156的枢轴销138延伸穿过形成于砧主体132中的开口139以及形成于夹爪部件156中的开口151，且接纳在形成于下部安装部分174中的开口173中以将下部安装部分174紧固到夹爪部件156(图3)。下部安装部分174界定用于接纳保持刀片176的狭槽177。如下文将进一步详细描述，保持刀片176包含弯曲的面向远端的表面176a(图4)以及一对限制部件176b(图4)。
驱动组合件180包含驱动部件182，其具有主体和工作末端184。工作末端184包含上部凸缘186a、下部凸缘186b、互连上部凸缘186a和下部凸缘186b的垂直撑杆186c，以及支撑于垂直撑杆186c上或形成到其中的刀187。上部凸缘186a被定位成可滑动地接纳于砧组合件130的通道131(图24)内，且下部凸缘186b被定位成沿着夹爪部件156的外表面156a(图24)可滑动地定位。在使用中，驱动部件182的远端移动最初将上部凸缘186a推进到形成于砧板134上的凸轮表面134b中，且将下部凸缘186b推进为与形成于夹爪部件156上的凸轮表面156b接合，以使芯筒组合件150朝向砧组合件130枢转到接近或关闭位置。在工作末端184移动通过工具组合件104时，驱动部件182的继续推进逐步地维持邻近于驱动组合件180的工作末端184在砧组合件130与芯筒组合件150之间的最小组织间隙。
驱动部件182的主体的远端支撑驱动部件182的工作末端184且界定止挡表面184a。致动橇162(图3)在芯筒组合件150(图3)内安置于工作末端184远端的位置处。当工作末端184在其最近端位置且工具组合件104处于打开或未接近位置(图24)时，橇162和工作末端184处于其初始位置。橇162包含多个凸轮表面166a，其被定位成在芯筒主体154的卡钉保持狭槽153b内接合且提升推动器164。推动器164(图3)定位于芯筒组合件150内以当橇162推进通过工具组合件104时从芯筒主体154排出卡钉“S”。橇162的近端包含一个或多个指状物166a，其界定开口或狭槽163(图4)，下文将进一步详细描述。
在某些实施例中，驱动部件182的主体由多个堆叠的材料(例如，不锈钢)片材182a到d形成。锁定部件188(图3)支撑于装载单元100的近端周围以防止驱动部件182的轴向移动直到装载单元100附接到钉合设备10(图1)。装载单元100的上文指出的组件的更详细论述在‘924专利中描述，所述专利已经以全文引用的方式并入本文。
参考图5到7，连接组合件190支撑于上部外壳半部110a的近端上，且提供装载单元100与外科钉合器10(图1)之间的电连接。连接组合件190包含连接器外壳192、接触部件194以及中继/间隔部件196。接触部件194包含一对接触部分194a，其接纳于连接器192的凹部193内。接触部分194a被定位成接合安置于外科钉合器10(图1)的长形主体14(图1)内的接触部件(未图示)的对应接触部分(未图示)。接触部件194包含在接触部分194a之间延伸的连接器部分194b。如上文所述，导体(例如，电丝带或电缆“R”或导线)延伸穿过装载单元100的近端主体部分102且进入工具组合件104以使连接组合件190与识别组合件200(图8)电耦合。
在装载单元100到外科钉合器10(图1)的长形主体14(图1)的附接期间，连接组合件190的接触部件194的接触部分194a被定位成接合支撑于外科钉合器10(图1)的长形主体14(图1)的远端内的连接器组合件(未图示)的接触部分(未图示)。连接组合件190的接触部件194a与外科钉合器10的连接器组合件的接触部件的接合使装载单元100的识别组合件200(图8)与外科钉合器10(图1)的手柄组合件12(图1)连接。如上所述，装载单元100可以借助卡口耦合或以任何其它合适方式附接到长形主体14。
现在参考图8到17，装载单元100的识别组合件200包含连接器组合件202和芯片组合件212。连接器组合件202包含连接器外壳204和突片204b。连接器外壳204具有凸缘部件204a，其接纳于工具组合件104的通道部件156中的开口157a(图10)内。突片204b接纳于通道部件156中的狭槽157b(图10)内以将连接器组合件202紧固到通道部件156。连接器外壳204接纳例如电丝带“R”(图11)的导体的远端，电丝带“R”从连接组合件190(图6)延伸以使连接组合件190(图7)的接触部件194与第一接触部件206a和第二接触部件206b电连通。在实施例中，连接器外壳204围绕电丝带“R1”的远端模制以使电丝带“R1”与第一接触部件206a和第二接触部件206b紧固在一起。当连接器外壳204紧固到夹爪部件156时，接触部件206a、206b从连接器外壳204向远端延伸。
芯片组合件212包含芯片外壳214和识别芯片218。突出部214a从芯片外壳214延伸且接纳在形成于芯筒组合件150的芯筒主体154(图12)的近端中的凹部155(图12)内，以将芯片组合件212紧固到芯筒主体154。芯片组合件212进一步包含第一接触部件216a和第二接触部件216b，其从芯片外壳214延伸且与识别芯片218连通。
当芯筒主体154接纳于夹爪部件156(图16)内时，第一接触部件216a和第二接触部件216b接合连接器组合件202的相应第一接触部件206a和第二接触部件206b。在实施例中，且如图示，连接器组合件202的第一接触部件206a和第二接触部件206b以及芯片组合件212的第一接触部件216a和第二接触部件216b以悬臂型式支撑于相应连接器外壳204和芯片外壳214上，以准许第一接触部件206a、216a之间以及第二接触部件206b、216b之间的搭扣接合。连接器组合件202的第一接触部件206a和第二接触部件206b以及芯片组合件212的第一接触部件216a和第二接触部件216b可以包含大体上球形形状以促进连接器组合件202与芯片组合件212之间的接合。
识别芯片218可以包含任何市售的芯片，其能够存储包含芯筒组合件150的规范的信息，例如芯筒大小、卡钉布置、卡钉长度、夹起距离、生产日期、型号、批号、到期日等，以及将所述信息中的至少一些发射到手柄组合件12(图1)。在一个实施例中，识别芯片218包含可擦除可编程只读存储器(“EPROM”)芯片。以此方式，附接的芯筒组合件150的配置可以中继到手柄组合件12，使得例如可以调整手柄组合件12的击发冲程的击发力和/或长度以适应特定芯筒组合件150。设想替代于EPROM，识别芯片218可以是读/写存储器芯片，例如读/写RAM，使得数据可以写入到识别芯片218上。举例来说，使用信息可以写入到识别芯片218上，其识别装载单元100已经完全或部分地击发以防止空的或部分击发的装载单元的再用，或用于任何其它目的。
特定参考图16到18，在芯筒组合件150于通道部件156内的装载期间，芯片组合件212的第一接触部件216a和第二接触部件216b接合连接器组合件202的第一接触部件206a和第二接触部件206b。一旦芯片组合件212的第一接触部件216a和第二接触部件216b与连接器组合件202的相应第一接触部件206a和第二接触部件206b接合，存储于芯片组合件212的识别芯片218上的信息就可在装载单元100连接到外科钉合器10的主体部分14后中继到手柄组合件12。如上文所述，识别组合件200经由导体(例如，延伸穿过装载单元100的电丝带或电缆“R1”(图7和11))以及通过安置于装载单元100的近端内的连接组合件190(图6)连接到外科钉合器10(图1)。
现在将参考图18到28描述击发封锁组合件220。击发封锁组合件220大体上类似于2014年3月31日提交的第14/230,516号美国专利申请(“‘516申请”)中描述的击发封锁组合件，且将仅参考其间的差异来详细描述。因此，‘516申请的内容以全文引用的方式并入本文。
击发封锁组合件220包含闩锁部件222，其以枢转方式支撑于下部安装部分174的远端上。闩锁部件222包含U形主体(图19)，其具有近端基座部件224以及两个间隔的远端延伸支腿226。如图示，基座部件224具备阻挡部件224a，其界定阻挡表面且焊接或紧固到基座部件224以对基座部件224提供额外支撑。替代地，基座部件224的近端可界定阻挡表面。闩锁部件222从第一位置(图21)枢转到第二位置(图22)。在图21中所示的第一位置中，闩锁部件222的阻挡部件224a与驱动部件182的止挡表面184a对准以防止驱动部件182在工具组合件104内的推进。在图22中所示的第二位置中，阻挡部件224a与驱动部件182的止挡表面184a未对准以准许驱动部件182在工具组合件104内的推进。
特定参考图18到20，闩锁部件222的支腿226中的每一者具有在中心定位的枢轴部件228以及对接表面230。枢轴部件228支撑于安装组合件170的下部安装部分174的钩臂174b(图20)上以将闩锁部件222以枢转方式支撑于下部安装部分174上。偏置部件包含一对弹簧232(图18)，其支撑在形成于下部安装部分174的远端面中的相应孔175a(图18)内以朝向第一位置推动闩锁部件222。每一弹簧232被定位成接合形成于闩锁部件222的相应对接表面230上的结块230a以在如图24中所见的逆时针方向上偏置闩锁部件222。每一支腿226的远端包含向下延伸的突出部234，其被定位成当橇162处于缩回位置、闩锁部件222处于第一位置且砧组合件130和芯筒组合件150处于接近位置时延伸穿过界定于橇162中的开口163(图20)。
一对弹簧236定位于夹爪部件156的内表面156b(图10)与界定于下部安装部分174的底部表面中的相应孔175b(图20)之间，以将工具组合件104推动到未接近位置(图2)。夹爪部件156包含用于接合弹簧236的一对圆柱体158(图10和11)。
参见图23和24，当驱动部件182处于完全缩回位置且工具组合件104处于未接近或打开位置时，驱动部件182的工作末端184的上部凸缘186a和下部凸缘186b分别在橇162的近端以及形成于砧板134和通道部件156上的凸轮表面238a、238b的近端间隔开。在工具组合件104的未接近位置中，闩锁部件222被弹簧232朝向逆时针位置推动。下部安装部分174包含表面240，其被定位成接合基座部件224或阻挡部件224a。下部安装部分174的阻挡部件224a与表面240之间的接合防止闩锁部件222的进一步逆时针旋转以将闩锁部件222保持于第一位置。如图25中所示，当击发封锁组合件220处于锁定配置时，阻挡部件224a接合下部安装部分174的角撑件174c以防止闩锁部件222的远端移动。
击发封锁组合件220的操作在‘516申请中详细描述。简要来说，在装载单元100的击发期间，击发封锁组合件220的闩锁部件222围绕下部安装部分174的枢轴部件174b枢转。如上文所述，保持刀片176接纳于下部安装部分174中的狭槽177内。如图26中图示，保持刀片176的弯曲表面176a适应闩锁部件222的阻挡部件224a的弓形运动，以防止在装载单元100的击发期间闩锁部件222的近端移动。闩锁部件222的近端移动可造成枢轴部件228与下部安装部分174的钩臂174b分离。在装载单元100的击发期间闩锁部件222与下部安装部分174的分离可能导致装载单元100的误击发和/或防止击发封锁组合件220恰当地起作用。
在装载单元100的击发之前，工具组合件104可以相对于近端主体部分102铰接。在工具组合件104的铰接期间，保持刀片176的限制部件176b接合第二耦合部件114b，所述第二耦合部件从装载单元100的近端主体部分102延伸以限制工具组合件104相对于近端主体部分102的铰接。
参考图29和30，芯筒组合件150的装运楔300被配置成在芯筒主体154的卡钉保持狭槽153b内维持卡钉“S”(图3)且防止在移除之前装载单元100的工具组合件104的致动。装运楔300包含长形主体302，其沿着长形主体的底部表面界定长形凹部303(图30)。凸缘304从长形凹部303内延伸，且包含多个凸起304以用于将凸缘304紧固于芯筒主体154(图29)的长形狭槽153a(图14)内。长形主体302的近端包含升高部分306(图29)，其被配置成防止一旦芯筒组合件150装载于工具组合件104的夹爪部件156(图2)内且在装运楔300的移除之前芯筒组合件150(图2)朝向砧组合件130(图2)接近。长形主体302的远端包含突出部308，其被定位且配置成由临床医生抓持以促进装运楔300与芯筒组合件150的分离。多个突片310从长形主体302延伸以用于接合芯筒组合件150的芯筒主体154，以将装运楔300可释放地紧固到芯筒组合件150的芯筒主体154。
现在参考图31和32，根据本公开的另一实施例的装载单元大体示出为装载单元400。装载单元400大体上类似于上文描述的装载单元100，且将仅关于其间的差异来描述。
装载单元400包含电导体，即柔性电缆或电丝带“R2”，用于电耦合安置于装载单元400的近端主体部分402的近端上的连接组合件190与安置于装载单元400的工具组合件404内的识别组合件200(图8)。柔性电缆“R2”包含应变消除部分，其包含多个线圈“c”。如图示，柔性电缆“R2”包含从柔性电缆“R2”的近端部分到柔性电缆“R2”的远端部分具有减小高度的七(7)个线圈“c”。设想柔性电缆“R2”可以包含多于或少于七(7)个线圈“c”和/或线圈的高度可以从近端部分到远端部分增加。替代地，线圈“c”的高度可为均匀的或者以随机或均匀方式变化。虽然示出为在线圈“c”之间具有均匀间距，但设想线圈“c”之间的间距可为不同的。
在装载单元400的工具组合件404相对于装载单元400的近端主体部分402的铰接期间，柔性电缆“R2”经历应变。柔性电缆“R2”经历的应变是连接组合件190近端主体部分402与安置于工具组合件404内的识别组合件200之间的距离在工具组合件404相对于近端主体部分402铰接时改变的结果。特定来说，连接组合件190与识别组合件200之间的距离在工具组合件404在第一方向上铰接时增加，如图31中的箭头“D”指示，且连接组合件190与识别组合件200之间的距离在工具组合件304在第二方向上铰接时减小，如图31中的箭头“E”指示。
柔性电缆“R2”的线圈“c”允许柔性电缆“R2”通过响应于柔性电缆“R2”上的应变而变形而具有可变长度。特定来说，当如图32中的箭头“A”指示张力施加于柔性电缆“R2”的远端时，如图32中的箭头“a1”指示的每一线圈“c”的挠曲和/或如图32中的箭头“a2”指示的线圈“c”相对于彼此的向外挠曲准许柔性电缆“R2”拉长，从而消除柔性电缆“R2”上的应变。当如图32中的箭头“B”指示压缩施加于柔性电缆“R2”时，如箭头“b1”指示的每一线圈“c”的向内挠曲和/或如图32中的箭头“b2”指示的线圈“R2”相对于彼此的向内挠曲准许柔性电缆“R2”缩短，从而消除柔性电缆“R2”上的应变。
装载单元400的近端主体部分402包含上部外壳半部410a和下部外壳半部410b。通道417延伸上部外壳半部410a的长度且接纳柔性电缆“R2”。通道417包含用于接纳柔性电缆“R2”的近端和远端部分的近端部分417a和远端部分417b，以及用于接纳柔性电缆“R2”的线圈“c”且当柔性电缆“R2”正经历应变时适应线圈“c”的挠曲的中心部分417c。
柔性电缆“R2”延伸装载单元400的近端主体部分402的长度且进入装载单元400的工具组合件404。柔性电缆“R2”电耦合与装载单元400的近端主体部分402一起安置的连接组合件190与安置于装载单元400的工具组合件404内的识别组合件200(图8)。柔性电缆“R2”可以松散地接纳于通道417内以准许柔性电缆“R2”的纵向移动。在一个实施例中，柔性电缆“R2”的近端使用例如粘合剂、包覆模制而轴向固定于通道417的近端部分417a内。
如上文所述，柔性电缆“R2”在装载单元400的主体部分402的近端与装载单元400的工具组合件404之间延伸。在装载单元400的工具组合件404相对于装载单元400的近端主体部分402的铰接期间，柔性电缆“R2”经历应变，即拉伸或压缩。特定来说，如图31中的箭头“D”指示工具组合件404相对于近端主体部分402在第一方向上的铰接如图32中的箭头“A”指示在柔性电缆“R2”的远端上产生拉力，且如图31中的箭头“E”指示工具组合件404相对于近端主体部分402在第二方向上的铰接如图32中的箭头“B”指示在柔性电缆“R2”的远端上产生推力。为了适应在工具组合件404的铰接期间由柔性电缆“R2”经历的应变，且从而防止柔性电缆“R2”的断裂和/或屈曲，如上文所述，柔性电缆“R2”的线圈“c”被配置成个别地且相对于彼此挠曲。在线圈“c”向外挠曲时，柔性电缆“R2”伸展，且在线圈“c”向内挠曲时，柔性电缆“R2”压缩。工具组合件404返回到非铰接位置造成柔性电缆“R2”的线圈“c”返回到非应变配置。
虽然示出且描述为并入到装载单元400中，但设想柔性电缆“R2”可以并入到具有铰接工具组合件且需要铰接工具组合件到手柄组合件的电耦合的任何装置中。
本领域的技术人员将理解，本文具体描述且在附图中图示的装置和方法是非限制性的示例性实施例。设想在不脱离本公开的范围的情况下，结合一个示例性实施例图示或描述的元件和特征可以与另一示例性实施例的元件和特征组合。本领域的技术人员还将基于上述实施例而了解本公开的另外特征和优点。因此，本公开不受已经特定示出且描述的内容限制，由所附权利要求书指示的除外。
