医疗器械10在图1中仅示意性地表示。例如，一个或多个医疗器械可以保持在支座中，该支座可以与连接部件6螺纹连接。医疗器械例如可以是采血泵、照明装置、探头等等。
所述球座5包括套筒5a，所述套筒具有前侧的用于球头4的止挡15。所述套筒在支撑臂1的第一端部上可以安装成，使得所述套筒相对于支撑臂1能围绕所述纵轴线x旋转并且不能轴向移动。所述止挡15具有用于与球头4接触的摩擦面，所述球头4能被锁止元件12压紧在所述止挡15的摩擦面上，使得所述套筒5a绕支撑臂1的纵轴线x的旋转被摩擦锁止。所述套筒5a包括第一套筒段21和第二套筒段24，所述第一套筒段套装在支撑臂1上，所述第一套筒段21和第二套筒段24通过连接元件22相互连接。在第一套筒段21与支撑臂1之间形成环形腔室，所述连接元件22容纳在所述环形腔室中。第一套筒段21和第二套筒段24分别具有内螺纹，所述连接元件22具有外螺纹，所述第一套筒段21的内螺纹和第二套筒段24的内螺纹旋拧在连接元件22的外螺纹上。连接元件22套装在支撑臂1上，止推元件23设置在支撑臂1的第一端部上并且使得所述连接元件22连同套筒5a相对于支撑臂1不能轴向移动。
锁止元件12构造成推杆，所述推杆具有能被操纵元件11操纵的后端部和用于与球头4共同作用的前端部，所述前端部设有面状的摩擦片14。所述摩擦片14构造成部分球面形的，并且能全表面地贴靠在球头4上。所述推杆的前端部能在支撑臂1的轴向方向上支撑在支撑臂1的第一端部上，并且所述前端部的摩擦面形成用于球头4的支撑面。在所述支撑臂1的空腔中设有弹簧13，所述弹簧以其一端支撑在支撑臂1上并且以其另一端支撑在锁止元件12上，所述弹簧使得锁止元件12朝球头4预紧。因此，即使操纵元件11处于松开状态，转动球头4或者套筒5a需要克服预定的较小的阻力。
支撑臂1能相对于支座部件2枢转。所述支撑臂1包括在第二端部上的接纳部件25，所述接纳部件构成为筒状部件并且接纳所述支座部件2。所述接纳部件25具有第一孔，所述支座部件2具有杆部37，所述杆部可旋转地接纳在所述第一孔中，所述杆部的纵轴线限定所述枢转轴线y。所述枢转轴线y与所述纵轴线x正交，并且处于一个共同的平面中。所述接纳部件25具有第二孔，所述操纵元件11接纳在所述第二孔中。所述第一孔和所述第二孔彼此相邻，并且所述第二孔的直径大于所述第一孔的直径。所述支座部件2的杆部37伸入到第二孔中。

所述操纵元件11具有斜面33，所述斜面构造成用于，与所述锁止元件12的后端部共同作用，所述操纵元件的操纵行程能经由所述斜面33转换成锁止元件12的移动行程。在旋拧头部35时，所述斜面33与头部35一起上升或者下降。所述斜面33可以构成为环绕的斜面。

所述支撑臂装置可以包括锁止器40，所述锁止器构造成用于可松开地锁止插头和插座的插接连接。在图1中，所述锁止器40构造成按钮装置，所述按钮装置包括按 钮头部41，通过按压按钮头部，所述锁止器40能在锁止状态与松开状态之间转换，在所述锁止器的锁止状态中，所述插头和插座的插接连接能被锁止，在所述锁止器的松开状态中，所述插头和插座的插接连接能被松开。所述按钮装置还包括与所述按钮头部41连接的按钮杆42，所述按钮杆被弹簧元件43预紧在初始位置上并且能从初始位置按压到预定的按压位置中，所述初始位置与锁止器40的锁止状态对应，所述按压位置与锁止器40的松开状态对应。所述按钮杆42具有用于限定初始位置的止挡45。所述按钮杆42接纳在支座部件2的空腔中，并且向上延伸直至贯穿操纵元件11并且从操纵元件11的端面露出。按钮头部41处于操纵元件11的端面的凹部中，并且能被按压操作。所述按钮装置包括接纳在插头的孔44中的活动元件，所述按钮杆42具有径向伸出部，在按钮杆42的初始位置中，所述活动元件被所述径向伸出部挤压并且因此从插座的表面伸出，在按钮杆的按压位置中，所述径向伸出部脱离所述活动元件。为清楚起见，所述活动元件在图1中未示出，以便可以更好地观察到插座中的用于活动元件的凹部。活动元件例如可以是销子。
在图1所示的实施方式中，同一个操纵元件11可以将球头4的转动运动、套筒5a绕纵轴线x的转动运动以及支撑臂1绕枢转轴线y的枢转运动锁止和释放。
图2是按照本发明的另外的实施方式的操纵臂装置的大大简化的俯视图。该操纵臂装置包括两个操纵臂1，其中，每一个操纵臂1以及接纳在该操纵臂中的各个部件例如锁止元件12、弹簧13、摩擦片14、球头4、套筒5a、止推元件23、连接元件22等等可以与在图1所示的实施方式中相同或类似地构成。相同的附图标记表示相同的部件。对于在图2中未描述的部件，可以参考图1以及针对图1的具体说明。
在一些未描述的实施方式中，两个操纵臂1可以具有共同的支座部件2和共同的接纳部件25，它们可以与在图1所示的实施方式中相同或类似地构成。因此，操纵元件11和锁止器40也可以与在图1所示的实施方式中相同或类似地构成。因此，两个操纵臂1能共同地围绕枢转轴线y枢转，两个球头4能分别转动，并且两个套筒5a能分别围绕各自的支撑臂的纵轴线x转动。同一个操纵元件11可以将两个球头4的转动运动、两个套筒5a绕纵轴线x的转动运动以及两个支撑臂1绕枢转轴线y的共同的枢转运动锁止和释放。
在一些未描述的实施方式中，两个操纵臂1可以具有共同的支座部件2并且分别具有自己的接纳部件25。两个接纳部件25重叠地套装在支座部件2的杆部37上。形象地说，将图1所示的杆部37朝上延长，在图1所示的接纳部件25与操纵元件11 之间添加一个另外的接纳部件25。因此，两个操纵臂1能彼此独立地围绕枢转轴线y枢转，两个球头4能分别转动，并且两个套筒5a能分别围绕各自的支撑臂的纵轴线x转动。同一个操纵元件11可以将两个球头4的转动运动、两个套筒5a绕纵轴线x的转动运动以及两个支撑臂1绕枢转轴线y的各自的枢转运动锁止和释放。
在图2所示的实施方式中，两个支撑臂1构成180°的夹角。不言而喻，它们也可以构成其他的夹角，例如60°、90°或120°的夹角。另外，也可以设置更多个支撑臂1。例如三个支撑臂1可以围绕共同的接纳部件25彼此隔开120°的角间距。
图3是按照本发明的另外的实施方式的操纵臂装置的大大简化的俯视图。该操纵臂装置包括一个操纵臂1和一个另外的臂1a。除了所述另外的臂1a之外，按图3的操纵臂装置可以与按图1的操纵臂装置相同或类似地构成。所述另外的臂1a是一个固定在操纵臂1的接纳部件25上的杆，该杆例如可以用来悬挂物品。在图3所示的实施方式中，操纵臂1与另外的臂1a构成180°的夹角，因此臂1a可以视为操纵臂1的延伸部分，当臂1a与操纵臂1具有相同的横截面且处于一条直线上时，尤其如此。换言之，支座部件2限定了操纵臂1的第二端部的位置，操纵臂1的在背离第一端部的方向上超过支座部件2的部分，即使是操纵臂1的一体的部分，可以视为操纵臂的延续部分。
不言而喻，它们也可以构成其他的夹角，例如60°、90°或120°的夹角。在一些未示出的实施方式中，一个或多个操纵臂1与一个或多个另外的臂1a的组合也是可能的。
图4是按照本发明的另外的实施方式的操纵臂装置的大大简化的侧视图。该操纵臂装置包括操纵臂1、球铰3和支座部件2。球铰3以及接纳在操纵臂1内的部件可以与图1的实施方式相同或类似地构成。支座部件2与操纵臂1固定地连接，例如一体地制成。接纳在支撑臂1中的锁止元件12以及接纳在操纵臂1的延续部分(或者说一个另外的臂)以及接纳在支座部件2中的操纵元件11分别用虚线表示。操纵元件11包括接纳在所述延续部分中的第一部分11a和接纳在支座部件2中的第二部分11b。支座部件2可旋转地插入到医疗装置的凹座中，该凹座具有作为摩擦面的内圆周面。在所述支座部件2的壁体中接纳活动的摩擦元件(未示出)。在操纵元件11被朝锁止元件12挤压时，第一部分11a压紧锁止元件，使得球头4和套筒5a被摩擦锁止，同时，第二部分11b将活动的摩擦元件压紧在凹座的内圆周面上，使得支座部件2相对于凹座的枢转运动也被摩擦锁止。凹座可以设有按钮装置(未示出)，用于防止支座 部件2从凹座中拔出。
最后要指出的是，本发明不限制于所示的和所说明的具体实施方式。本领域技术人员在这些实施方式的基础上做出的修改方案和变型方案同样落入本发明的保护范围内。
