摘要
探讨用解析几何原理研究颅骨的方法。建立颅骨某些结构的三维空间坐标系:即以Frankfurt平面,正中矢状面和垂直通过双耳门上点的额状面,作为三个互为垂直的基准坐标面,以三面的交线作为基准坐标轴线。把颅骨固定在作者改进的定颅器上。在各基面的水平位置上,利用测高游标卡尺垂直升降的特点,分别测量各测点与该面的垂直距,即坐标。测出了32个颅骨颅底内面解剖标志27项,共50个测点的三维坐标值。为临床手术和X线检查提供各种参考数据。
The purpose of the study is to explore an approach for measuring the human skull according to the principle of analytical geometry. In order to establish a three--dimensional coordinate system of the skull, three perpendicular planes(the universal Frankfurt horizontal plane, the median sagittal plane and the frontal plane through perpendicularly the porions) were used as three datum coordinate planes and the intersecting line of the three planes was used as the datum coordinate axis. The skull was fixed on the craniophore which can determine the location of the datum planes of the skull. Utiliing the vertical movement of a alti-vernier calliper on the horizontal location of each datum plane we measured the vertical distances (coordinate) of the measured points to the related datum plane, 27 body landmarks of the internal surface of cramal base of 32 adults human skulls and three-dimensional coordinate values of 50 measured points. The study provides a series of reference data for clinical operation and X-examination.
