目的研制代偿头位测量仪。方法根据代偿头位发生机理及三维特点,应用厚度2.0mm透明有机玻璃,利用电脑雕刻技术,制成两侧及前方为量角器,上方安置一个带刻度(0°～360°)指南针的四方体,每个量角器中心安有微型轴承指针,计量单位为0°～90°,利用重力作用及指南针指向恒定的特点,将该正方体通过固定头套置于头顶可同时精确测量水平、旋转及垂直代偿头位度数。此仪器能准确、方便的对代偿头位进行定量测量,对代偿头位诊断、手术设计及疗效评价极为有用。结论代偿头位测量仪对代偿头位诊断、手术设计及疗效评价有重要意义,有临床推广和实用价值。
Objective To develop compensation head measuring instrument. Methods According to the mechanism of occurrence of compensatory head position and the three-dimensional characteristics, a 2.0mm thick transparent plexiglass was used. Using computer engraving technology, a protractor on both sides and in front was made. A square (0 ° ~ 360 °) , Each protractor center with micro-bearings pointer, the unit of measurement 0 ° ~ 90 °, the use of gravity and the compass pointing constant characteristics of the cube through the fixed head cover placed on top of the head at the same time accurately measure the level of rotation and vertical compensation Head degree. This instrument can accurately and conveniently carry out quantitative measurement of compensatory head position, which is extremely useful for compensating head position diagnosis, surgical design and curative effect evaluation. Conclusion The compensation head measuring instrument is of great significance for diagnosis, operation design and curative effect evaluation of compensatory head position, and has clinical promotion and practical value.
