图2是侧视图，其示出作为实施例的根据本发明的多件式头板1。
FIG. 2 is a side view showing a multi-part head plate 1 according to the disclosure as an embodiment.
头板1用于在手术期间支撑躺在手术台30(参见图6)上的患者头部。
The head plate 1 serves to support the head of a patient lying on an operating table 30 (see FIG. 6 ) during an operation.
如图2所示，头板1包括用于耦联到手术台上的耦联装置2和两个头板段3和4。
As shown in FIG. 2, the head plate 1 comprises a coupling arrangement 2 for coupling to the operating table and two head plate segments 3 and 4.
在此，第一头板段作为竖起段3用于竖起头板1并且第二头板段作为头枕段4用于支撑患者头部。
In this case, a first head plate segment is designed as a positioning segment 3 for positioning the head plate 1 and a second head plate segment as a head support segment 4 for supporting the patient's head.
此外，头板1包括两个分别具有旋转轴线A和B的活节装置5、6，所述旋转轴线彼此间隔开(参见图2中的两个十字)。
Furthermore, the head plate 1 comprises two joint arrangements 5, 6, each with an axis of rotation A and B (see the two crosses in FIG. 2 ), which are spaced apart from one another.
竖起段3通过第一活节装置5可围绕旋转轴线A枢转地与耦联装置2连接，而头枕段4可围绕第二活节装置6的旋转轴线B相对于竖起段3枢转。
While the positioning segment 3 is pivotably connected to the coupling arrangement 2 via the first joint arrangement 5, the head support segment 4 can be pivoted relative to the positioning segment 3 about the axis of rotation B of the second joint arrangement 6.
头枕段4包括下面详细描述的操作装置23(参见图6)、如带衬垫的头支承板10、两个侧面滑轨8(在图2-5中仅示出一个)和一个位于端面的保持轨9，其用于固定附件、如操作设备、用于呼吸软管的软管保持器或输液架。
The head support segment 4 comprises an actuating device 23 described later in detail (see FIG. 6 ), an e.g. padded head support plate 10, two side slide rails 8 (only one is shown in FIGS. 2-5 ) and a front-positioned mounting rail 9 for attaching accessories, such as e.g. an operating device, a tube holder for breathing tubes or a drip stand.
耦联装置2包括用于例如分别固定在手术台30侧轨的一端上的两个销活节11(参见图6-10和13)。
The coupling arrangement 2 has two pin joints 11 for fastening in each case, for example, to one end of a side rail of an operating table 30 (see FIGS. 6-10 and 13 ).
在一些实施方式中，销活节11可分别具有横截面为“L形”的直角轮廓。
In some embodiments, the pin joints 11 can each have a right-angled profile that has an “L shape” in cross section.
例如耦联装置2可包括两个相对于患者支撑表面垂直定向的连接区段7和两个大致水平构造的销活节11。
For example, the coupling arrangement 2 can comprise two connecting sections 7, which are oriented perpendicularly to the patient support surface, and two pin joints 11 which are substantially horizontal.
图3-5示出根据本发明的头板1在头板段3和4的不同角度位置中的其它侧视图。
FIGS. 3-5 show further side views of the head plate 1 according to the disclosure in different angular positions of the head plate segments 3 and 4.
当前头板1允许通过竖起段3围绕旋转轴线A的第一旋转自由度在角度范围α1和α2内调节竖起段并且通过头枕段4围绕旋转轴线B的第二旋转自由度在角度范围β内调节头枕段，并且它们可逐阶地固定。
The present head plate 1 enables, via a first degree of freedom of rotation of the positioning segment 3 about the axis of rotation A, a displacement of the positioning segment in the angular ranges α1and α2and, via a second degree of freedom of rotation of the head support segment 4 about the axis of rotation B, a displacement of the head support segment in the angular range β, which can be fixed in stages.
竖起段3可从头板1的未调节的初始位置(其高度和定向在耦联状态中相应于患者支撑表面的高度和定向(图2))竖起倾斜角度α1或降下倾斜角度α2(图3和4)。
The positioning segment 3 can be positioned from an undisplaced initial position of the head plate 1, the height and orientation of which in the coupled state correspond to the height and orientation of the patient support surface (FIG. 2 ), by the inclination angle α1or lowered by the inclination angle α2(FIGS. 3 and 4 ).
另外，头板1可调节旋转角度β，即头枕段4以该旋转角度围绕第二活节装置6的旋转轴线B相对于竖起段3枢转。
In addition, the head plate 1 can be displaced by the angle of rotation β, in that the head support segment 4 is pivoted about the axis of rotation B of the second joint arrangement 6 relative to the positioning segment 3.
头板1的这种调节可能性的优点在于，在手术期间可毫无问题地实现患者的侧卧位。
These displacement possibilities for the top plate 1 have the advantage that a lateral positioning of the patient during an operation can be realized without problems.
为此使患者的头部(根据肩膀宽度)在身体支撑表面上方几厘米处枕在竖起的头枕段4上，以实现头部和肩膀肌肉的最佳放松，这相应于头部的阶梯式安置。
For this the patient's head—depending on the shoulder width—is stored a few centimeters above the body support surface on the positioned head support segment 4 in order to achieve optimal relief of the head and shoulder muscles, which corresponds to a stepped positioning of the head.
图6-8示出安装在手术台30上的、图2-5的头板1的内部结构。
FIGS. 6-8 show the internal structure of the operating table 30 mounted on the top plate 1 of FIGS. 2-5.
在此应注意，两个头板段3、4、活节装置5、6以及操作和锁止装置18、19、22相对于一个纵向延伸穿过头板1中心的平面镜面对称地构造。
It should be noted that the two head plate segments 3, 4, the joint arrangements 5, 6, and the actuating and blocking devices 18, 19, 22 are constructed in mirror symmetry with respect to a plane running longitudinally through the center of the head plate 1.
因此，为清楚起见，图6-8中仅示出头板一侧的构件。
For the sake of clarity, only components of a single top plate side are therefore shown in FIGS. 6-8.

操作装置23在每个头板侧上具有以操作套筒19形式的操作元件和与之刚性连接的切换板18以及以切换管17形式的同步元件，每个切换板18可与操作套筒19一起围绕切换管17的纵向轴线C枢转地支承。

The switching tube 17 connects the actuating sleeve 19 on the left side of the head plate to an actuating sleeve 19 on the right side of the head plate (see FIGS. 11, 12 ).
每个切换板18位于操作套筒19的朝向患者头部的一侧上并且这样构造，使得切换板在一端上具有卡锁元件(未示出)，这些卡锁元件沿第二活节装置6的径向方向接合到位于第二活节装置6中的容纳元件16中。
Each switching plate 18 is located on a side of the actuating sleeve 19 facing the patient's head and is designed such that it has latching elements (not shown) at one end which engage in a receiving element 16 located in the second joint arrangement 6 in the radial direction of this joint arrangement 6.
