基于计算机辅助设计3d打印的髋关节置换截骨导向器

Hip joint replacement cuts bone director based on computer aided design 3D prints

Abstract

本实用新型公开了一种基于计算机辅助设计3D打印的髋关节置换截骨导向器,包括导向器本体,导向器本体内表面与股骨小转子向外凸起面吻合;导向器本体的前端端面前倾角与股骨颈截骨面吻合,导向器本体的后端端面位于小转子内侧隆起高度的2/3处,导向器本体的第一侧面贴合于小转子的内侧缘,导向器本体的第二侧面贴合于小转子的外侧缘;导向器本体的前端向外的侧面上设置有两个间隔布置的凸起圆柱。本实用新型为理想的人工全髋关节股骨假体在体内的位置提供精准的截骨面,将摆锯倾斜面的角度、方向、位置固定精确,将手术的大部分工作放在术前准备,缩短了手术实施的时间,提高了手术的精确度,减少了手术风险。
The utility model discloses a hip joint replacement cuts bone director based on computer aided design 3D prints, including the director body, director body internal surface coincide with the outside crowning of thighbone lesser trochanter, the front end terminal surface front rake and the thighbone neck of director body cut the surface of bone and coincide, and the rear end terminal surface of director body is located 23 departments of lesser trochanter medial eminence height, laminate in the medial border of lesser trochanter in the first side of director body, laminate in the lateral border of lesser trochanter in the second of director body side, be provided with the protruding cylinder of two interval arrangements on the outside side of the front end of director body. The utility model discloses an artifical full hip joint femoral prosthesis position in vivo of ideal provides the accurate surface of bone that cuts, and with angle, direction, the rigidity accuracy on goose saw inclined plane, the most work that will perform the operation is put and is prepared before the art, has shortened the time that the operation was implemented, has improved the accuracy of performing the operation, has reduced the operation risk.
