具体实施方式
将参照附图详细说明本公开的手术设备以及用于所述手术设备的接合器和手柄组件的实施例，在几幅视图的每幅中，相同附图标记指代相同或对应的元件。如本文所用，术语“远侧”指的是手术设备或其部件的较远离用户的部分，而术语“近侧”指的是手术设备或其部件的较靠近用户的部分。
现在参考附图，其中在几个视图中相同的附图标记指示相似的部件，图1示出了根据本公开的原理的手术紧固件设备10。手术紧固件设备10包括手柄组件100、可安装至手柄组件100的接合器组件200以及可释放地可联接至接合器组件200的装载单元300。手柄组件100可以是具有手柄框架102、至少一个致动器并且在一些实施例中为两个或更多个致动器、以及适于控制紧固件设备10的操作的控制和/或安全开关104、106、108的任何手柄组件(可再用的或一次性的)。手柄组件100可以是动力的，例如，机电手柄，包括：电动机400；以及控制器500，其具有相关联的逻辑、软件或电路以控制电动机400的操作，并且继而控制接合器组件200和装载单元300的操作。致动器104、106、108可以与控制器500通信以控制手柄框架102内的电动机400和各种推动器、齿轮、连接杆和/或驱动部件的操作。手柄框架102包括用于将接合器组件200机械地安装至手柄组件100的手柄安装件110。手柄安装件110包括各种电路、接触器等，以与接合器组件200的各种对应的电部件电通信。可以通过参考Malinouskas等人的共同转让的美国专利公开第2011/0121049号或Zemlok等人的美国专利公开第2013/0214025号来确定用于与紧固件设备10一起使用的合适的手柄的进一步的细节，上述每个文献的全部内容都通过引用合并于此。
接合器组件200适于转换手柄组件100的机械部件的诸如旋转或直线运动的运动，以致动装载单元300。接合器组件200包括接合器安装件202和从接合器安装件202延伸并限定纵向轴线“k”的细长构件204。接合器安装件202包括各种接触器、开关或类似物，当接合器安装件202安装至手柄安装件110时，所述各种接触器、开关或类似物与手柄组件100的手柄安装件110内的协作部件通信，以控制接合器组件200和装载单元300的操作。细长构件204包括在细长构件204的近侧端208和远侧端210之间延伸的外管206。外管206支撑控制装载单元300的操作的一个或更多驱动机构。下面将讨论接合器组件200的进一步的细节。
继续参考图1，装载单元300可以是适于在组织上执行手术操作的单次使用装载单元(SULU)。还可以想到，装载单元300可以是适于例如用于一个或更多紧固件或吻合钉的顺序发射的多次使用装载单元(MULU)。在一个实施例中，装载单元300可以是适于在例如直线吻合操作或吻合术的连接中发射直线阵列的紧固件的SULU。根据本实施例，装载单元300包括细长主体302和安装在细长主体302的端部处的末端执行器或工具组件304。细长主体302能够相对于接合器组件200的外管206的远侧端210可释放地安装。末端执行器304包括砧座306和紧固件钉仓308。紧固件钉仓308容纳至少一排，例如优选为各自都布置成直线阵列的多排紧固件或吻合钉(未示出)。砧座306和紧固件钉仓308适于在打开位置(图1)和接近位置之间的相对运动。紧固件被从紧固件钉仓308驱动通过定位在部件周围或定位在部件之间的组织，并且由砧座306压曲。如图2中最佳地示出的，结合图1，细长主体302还包括与接合器组件200机械联接的安装翼片312和一对直径相对的安装凸耳310。此外，至少一个，例如两个电接触器314安装至细长主体302。接触器314可以与存储与装载单元300相关的参数的存储芯片相关联或者相通信，其中所述参数为例如序列号、类型、尺寸、吻合钉或紧固件尺寸、长度、最大冲程数量、装载单元的早先使用等。可以通过参考Zergiebel等人的、2015年9月24日提交的序列号为14/863,558的共同转让的美国专利申请来确定装载单元300的进一步的细节，上述申请的全部内容通过引用合并于此。
现在参照图2至图6，现在将讨论接合器组件200的激活机构。激活机构212向临床医生提供装载单元300已经被适当地安装至接合器组件200的正反馈，并且与在装载单元300内相关联的存储器或逻辑结合，向临床医生提供关于装载单元300的细节(包括类型、使用等)。激活机构212还允许多个装载单元300的重复安装而不经历其在接合器组件200内的机械和/或电部件的任何性能变差，从而增强接合器组件200的可用性并确保接合器组件200在经过扩大的使用次数后的适当工作。
激活机构212包括安装在细长构件204的外管206(在图2中示出为部分地移除)内的开关致动器214。在一个实施例中，开关致动器214相对于细长构件204的内壳体216安装，并且适于在第一和第二纵向位置之间相对于内壳体216纵向移动。图2示出了开关致动器214的第一或初始位置。开关致动器214包括激活连杆218和联接至激活连杆218的开关柱塞220。激活连杆218包括：近侧安装部222，其具有纵向狭槽224；以及远侧臂部226，其从近侧安装部222伸出。远侧臂部226具有从其伸出的大致细长的臂末端230。远侧臂部226还限定邻近臂末端230与远侧臂部226的相交处的止动表面232(图5)。安装突片234从激活连杆218的中间部径向向外突出。安装突片234限定大致矩形横截面并且具有稍微弯曲或弓形的轮廓。
继续参考图2至图6，开关柱塞220包括柱塞框架236，柱塞框架236限定贯通其的大致矩形开口238(图3和图5)以用于接收激活连杆218的安装突片234。特别地，开关柱塞220的矩形开口238和安装突片234的矩形横截面对应地确定尺寸，从而安装突片234可以插在矩形开口238内以联接两个部件。选择安装突片234和开口238之间的公差，使得安装突片234可以能够在当安装在细长构件204内时沿横向于纵向轴线“k”的方向有限的滑动运动，例如，在一个实施例中，安装突片234不直接紧固至开关柱塞220的柱塞框架236。开关柱塞220包括柱塞延伸部或突片240。开关柱塞220的柱塞框架236至少部分地接收在内壳体216的凹槽242(图2和图6)内，并且适于在开关致动器214在第一和第二纵向位置之间纵向移动期间穿过凹槽242。凹槽242对应地定尺寸以限制开关柱塞220的横向移动。具体地，凹槽242(图6)的宽度“m”基本对应于例如略大于柱塞框架236的宽度“b”。(图3)以该尺寸，柱塞框架236在有效地穿过凹槽242的同时以基本上直线方式移动而没有横向移动。
如图2和图6中最佳地示出的，开关致动器214通常通过弹性构件或弹簧244而被沿远侧方向偏置，例如朝向第二纵向位置偏置。弹簧244在其近侧端处接合细长构件204的内壳体216的弹簧支撑壁246，并且在其远侧端处接合激活连杆218的弹簧支承表面248。弹簧支撑壁246还在激活连杆218的纵向狭槽224内延伸，并且通过穿过纵向狭槽224而用作导轨，从而使开关致动器214在第一和第二纵向位置之间纵向移动期间的横向移动最小化。
现在参照图4至图5，与图2一起，接合器组件200的激活机构2还包括至少部分地安装在设置在细长构件204的远侧端210处的帽部252(图2)内的可旋转锁定构件250。可旋转锁定构件250适于相对于接合器组件200在对应于装载单元300的解锁状态(图2)和锁定状态的两个角位置之间，围绕纵向轴线“k”旋转。可旋转锁定构件250包括通过连接臂258互连的第一和第二环部254、256。第一环部254包括至少一个或更多电接触器260，当装载单元300安装至接合器组件200时，电接触器260可以与控制器500通信以传输与装载单元300相关联的数据。第二环部256限定与装载单元300联接的、直径相对的凹槽262、264。凹槽262限定在从第二环部256向外伸出的一对腿266之间。
第二环部256还具有安装至其外表面的致动器止动件268。致动器止动件268可以是圆柱形杆，所述圆柱形杆布置成当可旋转锁定构件250处于图2的解锁状态时基本纵向对准开关致动器214，具体为激活连杆218的止动表面232。在这个位置，激活连杆218的止动表面232接合致动器止动件268，从而防止开关致动器214(响应于弹簧244的弹簧偏置)沿远侧方向朝向其第二纵向位置移动。
再次参考图2和图6，将描述接合器组件200的进一步的细节。接合器组件200还包括安装至细长构件204的内壳体216的电开关270，电开关与开关柱塞220的柱塞延伸部240大致纵向对准。开关270配置为响应于包括开关柱塞220的开关致动器214的移动而拨动(例如拨动开关)到第二纵向位置，这发生在装载单元300联接至接合器组件200时。开关270与控制器500电通信，并且可以包括逻辑、电路或软件以在控制器500激活和去激活时将一个或更多电信号发送到控制器500。如图7中最佳地示出的，开关密封或外膜272(其一部分示出为被移除)可以包围开关270以保护其部件。外膜272可以是弹性体的盖或类似物。开关270和开关柱塞220的柱塞延伸部240可以具有基本相同的横截面积“a1”、“a2”(图3和图7)，以确保柱塞延伸部240与开关270的适当的直接接触和激活。
接合器组件200还包括延伸穿过外管206并超出帽部252的驱动构件274。驱动构件274在手柄组件100和接合器组件200联接时可机械地联接以驱动手柄组件100的部件。连接器276包括在驱动构件274中，并且配置为并定尺寸为用于与装载单元300的相关联的驱动机构选择性的接合，以控制装载单元300的操作。
现在将讨论激活机构212的操作。手柄组件100和接合器组件200通过将接合器组件200的接合器安装件202插入手柄组件100(图1)的手柄安装件110内而联接。此后，装载单元300与接合器组件200的细长构件204的帽部252对准，使得装载单元300的安装凸耳310与可旋转锁定构件250的第二环部256的安装凹槽262、264对准，如图2所示出的。装载单元300被引入帽部252内，由此安装凸耳310接收在可旋转锁定构件250的安装凹槽262、264内，并且接合器组件200的驱动构件274定位在装载单元300内，如图6和图8所示的。装载单元300的安装翼片312也容纳在由连接臂258限定的下层凹槽内。在这个位置，可旋转锁定构件250的致动器止动件268以防止开关致动器214沿远侧方向朝向第二纵向位置移动的方式接合激活连杆218的止动表面232。在一个实施例中，开关致动器214可以处于第二纵向位置使得在装载单元300插入可旋转锁定构件250期间，致动器止动件268可接合激活连杆218的止动表面232，以将开关致动器214移动至第一纵向位置。
在操作的这一点上，可旋转锁定构件250相对于装载单元300的安装凸耳310处于解锁状态。装载单元300的电接触器314与可旋转锁定构件250的第一环部254的电接触器260接合(图6)。
参照图9和图10，装载单元300围绕纵向轴线“k”向锁定状态旋转(沿方向箭头“p”的角方向)，这引起可旋转锁定构件250由于装载单元300的安装凸耳310与可旋转锁定构件250的安装凹槽262、264的接合(例如，与限定凹槽262的腿266和/或与第二环部256的限定凹槽264的表面接合)而对应地旋转。在向锁定状态旋转时，致动器止动件268偏离或移出与激活连杆218的纵向对准从而允许包括开关柱塞220的开关致动器214在弹簧244的影响下沿远侧纵向方向(方向箭头“w”)向图9的第二纵向位置推进。在该移动期间，开关柱塞220的柱塞框架236以直线方式穿过内壳体216的凹槽242，使得柱塞延伸部240保持与开关270的纵向对准。由于凹槽242和柱塞框架236的协作尺寸，开关270不受到可能影响开关密封或外膜272和/或开关部件的完整性的任何离轴力。另外，在旋转期间，由于激活连杆218的安装突片234在柱塞框架236的开口238内的自由联接，开关致动器214的激活连杆218可被允许略微横向地或向外地移动，即，安装突片234可以滑动以适应在可旋转锁定构件250的旋转期间激活连杆218可能经受的任何径向向外的力或扭矩力。这使得开关柱塞220的在开关柱塞220的穿过移动之前和/或期间的任何离轴或角运动最小化，以保持操作部件的完整性并确保柱塞延伸部240与开关270的直接接触。在第二纵向位置，开关致动器214的柱塞延伸部240接合并激活开关270，由此开关270将装载单元300与接合器组件200接合的信号“s1”(在图9中示意性地示出)发送到控制器500。装载单元300和可旋转锁定构件250的电接触器314、260发送至少一个信号“s2”(也在图1中示意性地示出)，以将与装载单元300相关联的数据传送到控制器500，用于供临床医生检查。
