现在参考图2和图3，接合器组件100包括联接组件102、相对于联接组件102支撑的手柄组件104、从手柄组件104向远侧延伸的细长主体部106以及延伸穿过联接组件102、手柄组件104和细长主体部106的驱动组件108(图3)。联接组件102将接合器组件100选择性地固定到致动组件10(图1)。驱动组件108延伸穿过接合器组件100的联接组件102、手柄组件104和细长主体部106，并且被构造成将动力从致动组件10(图1)传递到附接的末端执行器，即工具组件30(图1)，用于实现工具组件30的致动。
继续参考图2和图3，简单来讲，接合器组件100的驱动组件108包括被构造成与致动组件10的第一驱动构件、第二驱动构件和第三驱动构件(未示出)可操作地连接的第一连接器160a、第二连接器160b和第三连接器160c(图2)。如图3中所示，第二连接器160b可操作地连接到细长驱动轴162，用于使旋转运动经过接合器组件100传递。第一连接器160a和第三连接器160c中的每一个可操作地连接到支撑在接合器组件100内的行星齿轮组件164(图3；仅示出了一个)。该行星齿轮组件164构造成将来自致动组件10的旋转运动转变成纵向运动。对于包括示例性联接组件和示例性驱动组件的示例性接合器组件的详细描述，请参考'766申请，其内容先前已并入本文。
现在特别参考图3，接合器组件100的手柄组件104包括基部构件或芯部110、可旋转地支撑在基部构件110上的旋转手柄120，以及可操作地支撑在旋转手柄120上的锁定机构130。如将在下面进一步详细描述的，当锁定机构130处于解锁配置(图9和图10)时，旋转手柄120能够相对于基部构件110沿着纵向轴线“x”旋转，而当锁定机构130处于锁定配置(图7和图8)时，旋转手柄120相对于基部构件110旋转地固定。特别地，旋转手柄120围绕接合器组件100的纵向轴线“x”的旋转引起限定纵向轴线“y”(图1)的末端执行器(即，工具组件30(图1))相对于接合器组件100的纵向轴线“x”进行关节式运动或枢转，以允许工具组件30相对于致动组件10定位。由此，临床医生能够使工具组件30相对于致动组件10定向，而不改变致动组件10的定向。
另外参考图4，基部构件110包括大致圆柱形构件112，其限定一对纵向开口113a、113b，用于接收穿过其中的驱动组件108(图3)。基部构件110包括近侧圆形凸缘114和远侧圆形凸缘116，并且进一步限定了近侧圆形沟槽115和远侧圆形沟槽117。近侧圆形凸缘114有助于将手柄组件104的基部构件110附接到联接组件102。近侧圆形沟槽115容纳旋转手柄120的圆形凸缘126，以将旋转手柄120可旋转地固定到基部构件110。
仍旧参考图3和图4，基部构件110的远侧圆形凸缘116和远侧圆形沟槽117与手柄组件104的锁定机构130结合操作，以将旋转手柄120相对于基部构件110以固定旋转定向固定。特别地，基部构件110的远侧圆形凸缘116限定第一径向切口117a、第二径向切口117b和第三径向切口117c，上述切口被构造成选择性地接收锁定机构130的锁定构件134的锁定部146。尽管被示出为第一切口117a和第三切口117c彼此对置且第二切口117b定向成垂直于第一切口117a和第三切口117c，但可以想到，远侧圆形凸缘116可以限定任何数量的切口，并且切口可以布置成任何合适的配置。例如，切口可以以设定的间隔布置，并且在驱动组件108允许的地方，切口可以完全围绕远侧圆形凸缘116延伸地形成，以允许将旋转手柄120锁定在围绕基部构件110的任意三百六十度(360°)的定向。
继续参考图3和图4，旋转手柄120包括截头圆锥体122，其具有被构造为由用户可操作地接合的多个凸脊124(图1)。细长主体部106(图2)被固定到旋转手柄120，使得旋转手柄120围绕接合器组件100的纵向轴线“x”的旋转引起细长主体部106围绕纵向轴线“X”的旋转。以这种方式，固定到接合器组件100的细长主体部120的末端执行器(例如，工具组件30(图1))，或固定到例如延伸组件20(图1)的延伸组件(所述延伸组件固定到接合器组件100的细长主体部120上)的末端执行器，能够独立于接合器组件100所附接到的致动组件10(图1)的运动而旋转。
如上所述，旋转手柄120包括圆形凸缘126(图3或图4)，其被接收在基部构件110的近侧圆形沟槽115内以允许旋转手柄120相对于基部构件110旋转。旋转手柄120限定用于可操作地接收锁定机构130的径向开口123。旋转手柄120中的开口123定位成与基部构件110的远侧圆形沟槽117对齐或对准，使得锁定机构130的锁定构件134可以由远侧圆形沟槽117接收并且可选择性地接收在远侧圆形凸缘116中的第一切口117a、第二切口117b和第三切口117c的每一个内。
另外参考图5和图6，接合器组件100的手柄组件104的锁定机构130包括用于使锁定机构130脱离的按钮或闩锁构件132。锁定机构130还包括布置在旋转手柄120内并且能够相对于按钮构件132枢转的锁定构件134。第一弹簧构件(例如，压缩弹簧136)将锁定构件134偏置到锁定配置(图5)。
继续参考图4和图5，锁定机构130的按钮构件132包括构造成由用户可操作地接合的基部140以及从基部140延伸用于接合第一弹簧构件136的凸缘142。按钮构件132的基部140可以包括用于向用户指示的标记，例如，旋转手柄120的旋转方向。如所示的，按钮构件132的基部140包括双面箭头“I”，其指示手柄组件104能够围绕纵向轴线“x”旋转。
锁定机构130的按钮构件132限定用于接收锁定构件134的凹部141(图3)和形成在凹部外侧的一对圆柱形开口141a，所述一对圆柱形开口141a用于枢转地接收锁定构件134的枢转构件152。唇缘140a沿着圆柱形开口141a延伸，用于相对于按钮构件132枢转地保持锁定构件134。凸缘142包括突出142a，其构造成与旋转手柄120的表面120a接合以将按钮构件132保持在旋转手柄120中的开口123内。突起142a还与锁定机构130的第一弹簧构件136接合。特别地，第一弹簧构件136将锁定机构130的按钮构件132沿径向向外的方向偏置。
另外参考图6，锁定机构130的锁定构件134包括枢转部144和锁定部146。锁定构件134的枢转构件152从枢转部144向外延伸并且构造成接收在锁定机构130的按钮构件132中的圆柱形开口141a内。锁定构件134的锁定部146构造成选择性地接收在基部构件110的远侧圆形凸缘116中的第一径向切口117a、第二径向切口117b和第三径向切口117c内。凹口143形成在锁定构件134的枢转部144和锁定部146之间。如下面将进一步详细描述的，在锁定机构130处于解锁位置时，凹口143与基部110的远侧圆形凸缘116的对准允许旋转手柄120相对于基部构件110旋转。
第二弹簧构件(例如，板簧148)相对于锁定构件134固定并且接合旋转手柄120的第二表面120b。如下面将进一步详细描述的，在锁定机构130的按钮构件132释放之后，第二弹簧构件148使锁定构件134返回到锁定位置(图3)。
现在将参考图7至图11描述锁定机构130的操作。首先参考图7和图8，锁定机构130被示出为处于锁定配置。特别地，锁定构件134的锁定部146被接收在基部构件110的远侧圆形凸缘116中的第一切口117a内。在锁定配置中，锁定机构130的按钮构件132被弹簧构件136径向向外偏置。如上所述，按钮构件132通过从按钮构件132的凸缘142延伸的突起142a保持在旋转手柄120的开口123内。
现在参考图9和图10，如由图9中的箭头“A”所示的，当锁定机构130的按钮构件132被按下时，按钮构件132克服弹簧构件136的偏置而径向向内移动。随着按钮构件132径向向内移动，锁定构件134克服板簧148的偏置而绕枢转构件152(图6)沿着如由图9中的箭头“B”所示的逆时针方向枢转。锁定构件134的逆时针枢转使锁定构件134的锁定部146从基部构件110的远侧圆形凸缘116的第一径向切口117a内移动，使得锁定构件134的枢转部144和锁定部146之间的凹口143与远侧圆形凸缘116对准。
现在转到图11，一旦锁定机构130处于解锁配置，则旋转手柄120可以相对于基部构件110旋转，如由箭头“C”所示的。按钮构件132的释放允许弹簧构件136将按钮构件132偏置到其初始位置。类似地，板簧148将锁定构件134偏置到其初始位置。当锁定构件134与基部构件110的远侧圆形凸缘116的第一径向切口117a、第二径向切口117b和第三径向切口117c中的一个对准时，锁定构件134的锁定部146接收在相应的第一切口117a、第二切口117b和第三切口117c内，这将旋转手柄120相对于基部构件110旋转地锁定。
锁定机构130可以在整个手术过程中使用来使接合器组件100的细长主体部106相对于致动组件10(图1)旋转。在手术操作之后，接合器组件100可被灭菌并重新使用。
考虑到强度、耐久性、耐磨性、重量、耐腐蚀性、制造容易性、制造成本等，本文所述的任意部件可以由金属、塑料、树脂、复合材料等中的任一种制造。
