研发曲面定位型髋臼后柱置钉瞄准器,论述该型瞄准器的曲面定位方式的可行性,以及其在定位精度、精度稳定性方面的优势。针对后柱安全置钉通道与髂骨翼之间产生的干涉现象,提出解析法与作图法的解决方案,先采用解析法寻找出安全置钉通道圆柱体上距髂骨翼表面最远的母线;再采用作图优化法,以从大到小的金属接骨螺钉直径为离散变量,在后柱安全置钉通道范围内逐步调控,直至置钉通道与髂骨翼外包容平面的夹角、钻头与髂骨翼表面的间隙满足瞄准器结构设计的需要及手术钻削螺纹底孔的操作需要;最后采用着色实验验证3D打印技术对于设计制造曲面定位型置钉瞄准器的适应性,采用螺纹底孔钻削实验验证后柱置...

A curved positioning acetabular posterior column staple sight was developed.The feasibility of the surface positioning method of this type of sight and the comparative advantages in positioning accuracy and precision stability are discussed.Aiming at the interference phenomenon between the safe placement of the posterior column and the humeral wing,the solution of the analytical method+mapping method is proposed.Firstly,the analytical method is used to find the safest nailing channel.Far busbar;then using the mapping optimization method,the diameter of the metal bone screw from large to small ...
