现在转向图7A和7B,手术组合件10的手术器械200包含器械主体210和从器械主体210向远侧延伸到末端执行器202(参见图2)的器械轴212。再次简要参考图3,器械主体210还在器械主体210中限定夹持孔口210a,所述夹持孔口210a可例如由临床医师的手指或其它工具接合以促进将手术器械200插入到器械驱动单元100中和/或从器械驱动单元100移除手术器械200,如下文更详细描述。
参考图7A,手术器械200的器械主体210包含主体部分214和支撑在主体部分214上的头部分216。器械主体210的主体部分214在其中限定沿着其纵向延伸的通道214a。器械主体210的主体部分214进一步包含从其外表面并沿着主体部分214纵向延伸的凸缘218。尽管图7A中仅示出第一凸缘218a,但类似于第一凸缘218a的第二凸缘设置在主体部分214的相对侧上,与第一凸缘218a处于镜像关系。
再次参考图2到4,当手术器械200的器械主体210被插入器械驱动单元100的U形通道102g和/或从所述U形通道102g取出时,手术器械200的器械轴212和末端执行器202可通过器械驱动单元100的主体102的底板102h的中心孔口接收。手术器械100的凸缘218通过器械驱动单元100的两对相对锥形化表面102k、102l的引导而可接收在器械驱动单元100的侧通道102i内以将手术器械200的器械主体210支撑在器械驱动单元100的U形通道102g内。凸缘218被配置成当手术器械200的凸缘218接收在器械驱动单元100的侧通道102i内时使手术器械200维持与器械驱动单元100共轴对齐。
再次参考图7A和7B,手术器械200进一步包含可滑动地支撑在手术器械200的器械主体210的每个通道214a中的器械突片220。手术器械200可包含任何数目的器械突片220且可限定任何数目的通道214a以容纳围绕器械主体210的主体部分214和/或纵向轴线“X1”隔开定位的器械突片220。
如图7B所见,手术器械200的每个器械突片220包含上表面220a、下表面220b、第一侧表面220c和第二侧表面220d。器械突片220包含通过连接构件226连接的前面222和背面224。器械突片220的前面222限定从下表面220b、跨越前面222并朝向上表面220a延伸的成角表面222a。器械突片220的背面224限定穿过其的通道224a,所述通道224a在其中接收手术器械200的连接构件“CM”。背面224包含成角侧表面224b。器械突片220的一对侧凹槽228a、228b限定在器械突片220的第一侧表面220c和第二侧表面220d中,位于器械突片220的前面222与背面224之间。器械突片220的这一对侧凹槽228a、228b可与器械主体210的主体部分214接合以使得手术器械200的相应器械突片220能够沿着器械主体210的通道214a中的相应一个轴向滑动。
参考图3、4和8到14,为了将器械驱动单元100的适配器组合件107耦接到手术器械200的器械突片220,手术器械200的器械主体210被推进到器械驱动单元100的U形通道102g中。当手术器械200的器械主体210被推进到器械驱动单元100的U形通道102g中时,手术器械200的凸缘218沿着器械驱动单元100的相对通道102i滑动,直到手术器械200的器械主体210的底表面接触器械驱动单元100的底板102h为止。凭借设置在器械驱动单元100的相应电机组合件103的轴106的下部部分上的器械驱动单元100的一个或多个适配器组合件107,相应电机组合件103的电机104被激活以使相应电机组合件103的轴106旋转,由此使器械驱动单元100的相应适配器组合件107轴向向上和/或远离器械驱动单元100的底板102h移动。
如图10A到12B所见,器械驱动单元100的适配器组合件107朝向电机组合件103的电机104的移动(例如,向上)致使适配器组合件107的突片锁110的肩状物110e接触手术器械200的器械突片220的前面222的成角表面222a,从而使得突片锁110的肩状物110e沿着器械突片220的前面222的成角表面222a凸起。如由箭头“A”指示,器械驱动单元100的突片锁110的锁定臂110b围绕突片锁110的纵向轴线“X2”从第一位置并远离适配器组合件107的止动壁108i朝向第二位置旋转。当突片锁110的锁定臂110b远离适配器组合件107的止动壁108i旋转时,突片锁110的弹簧110c向突片锁110的锁定臂110b施加偏置力。当突片锁110的肩状物110e沿着手术器械200的器械突片220的前面222的成角表面222a凸起时实现突片锁110在第一与第二位置之间的旋转。
当器械驱动单元100的突片锁110的锁定臂110b远离第一位置(例如,初始位置)旋转而抵靠适配器组合件107的适配器主体108的止动壁108i时,手术器械200的器械突片220接收在适配器组合件107的器械突片底座108d内。在完全安置位置中,手术器械200的器械突片220的下表面220b接触适配器组合件107的器械突片底座108d的底表面108g。一旦手术器械200的器械突片220完全安置在器械驱动单元100的器械突片底座108d内且适配器组合件107的突片锁110的锁定臂110b的底表面110f已上升高于手术器械200的器械突片220的上表面220a,来自突片锁110的弹簧110c的偏置力就使突片锁110的锁定臂110b在手术器械200的器械突片220上方从突片锁110的第二位置往回朝向突片锁110的第一位置(例如,抵靠适配器主体108的止动壁108i)旋转,如由箭头“B”指示。
参考图13,一旦器械驱动单元100的突片锁110的锁定臂110b返回到第一位置、同时手术器械200的器械突片220完全安置在适配器组合件107的器械突片底座108d中时,突片锁110的锁定臂110b的底表面110f接触器械突片220的上表面220a,从而使得突片锁110的指状物110d覆盖适配器组合件107的器械突片底座108d并将手术器械200的器械突片220紧固在适配器组合件107的器械突片底座108d内。当手术器械200的器械突片220紧固在适配器组合件107的器械突片底座108d内时,激活电机组合件103致使器械突片220与适配器组合件107一起沿着轴向方向平移,如由箭头“C”指示。更确切地说,激活电机组合件103的电机104会使电机组合件103的轴106旋转从而经由适配器组合件107的带螺纹管构件108h沿着电机组合件103的轴106轴向驱动适配器组合件107。适配器组合件107的轴向移动赋予手术器械200的器械突片220相对于手术器械200的器械主体210的伴随轴向移动。如上文所论述手术器械200的器械突片220的轴向移动致使手术器械200的末端执行器202实现末端执行器202的操作。
如图14所见,器械驱动单元100的任何数目的适配器组合件107可耦接到如上文所描述的手术器械200的相应器械突片220,以使得末端执行器202能够进行各种功能,例如抓握、铰接、旋转等。
参考图2到14,为了从手术器械200的相应器械突片220释放和/或解耦器械驱动单元100的适配器组合件107中的一个或多个,可手动和/或以电子方式使相应适配器组合件107的突片锁110往回朝向突片锁110的第二位置旋转,从而使得手术器械200的相应器械突片220可与器械驱动单元100的相应适配器组合件107的器械突片底座108d分离。在实施例中,适配器组合件107的一个或多个组件(例如,适配器组合件107的一个或多个管构件108h和/或突片锁110)可包含协作来使得器械驱动单元100的电机组合件103能够以电子方式使突片锁110中的一个或多个旋转的再一个齿轮、齿状物、轴承、弹簧等。在一些实施例中,一个或多个独立电机组合件103可耦接到和/或可与突片锁110接合从而以电子方式使突片锁110相对于相应适配器主体108旋转。在某些实施例中,适配器组合件107可被推进到支撑在电机组合件103的轴106上的接合齿轮(未示出)以接合与适配器主体108和/或突片锁110关联的轴承组合件(未示出),以使得电机组合件103能够以电子方式使突片锁110旋转。
一旦手术器械200的每个器械突片220与其相应适配器组合件107分离,手术器械200就可与器械驱动单元100分离;例如以进行器械交换。
器械驱动单元100的适配器组合件107中的一个或多个可独立于其它适配器组合件107中的一个或多个耦接到和/或与手术器械200的其相应器械突片220解耦。另外和或或者,适配器组合件107中的两个或多于两个可同时耦接到和/或与其相应器械突片220解耦。
