Abstract

本实用新型公开了一种由生物适应性材料制成可随意依人工髋关节临床手术需求而改变的组合式人工髋关节柄。其特征在于：它由一块与人体股骨大转子与小转子间骨髓腔形状吻合之金属块、镶嵌在金属块上邻近大转子方向之两面的金属片及一根与金属块以螺纹状结构紧密结合之金属棒组合成。

Description

组合式人工髓关节柄
本实用新型涉及医学领域中的一种人造股骨头，具体说是一种组合式人工髋关节柄。
传统的人工髋关节柄10(如图5)因为整体成型制作，故其制造工艺较复杂，且因其表面喷涂或加工部位9为不规则角度，喷涂不均匀，造成日后临床上容易脱落现象。另因为整体柄制作精密，加工其各项夹具及工艺均要求极高，不易达到标准化的产品，生产品种尺寸过多，因而造成库存需求量大，成本极高。
本实用新型的目的在于提供一种由生物适应性材料制成可随意依人工髋关节临床手术需求而改变的组合式人工髋关节柄。
为了实现上述目的，本实用新型采用如下技术方案：一种组合式人工髋关节柄，其特征在于：它由一块与人体股骨大转子与小转子间骨髓腔形状吻合之金属块、镶嵌在金属块上邻近大转子方向之两面的金属片及一根与金属块以螺纹状结构紧密结合之金属棒组合成。
本实用新型与传统的技术相比，具有显而易见的优点：
1、采用组合式结构，各部件易加工，提高了加工质量，实现标准化产品生产，减少库存量，降低成本。
2、金属片表面喷涂均匀，临床上不易脱落，且不同表面处理的金属片可交互更换，适应各类髋关节病症之需求。
以下结合附图和实施例对本实用新型作详细说明。
图1为本实用新型一个较佳实施例结构示意图；
图2为图中金属片结构示意图；
图3为图1金属块上邻近大转子方向之两面可镶嵌式凹槽结构示意图；
图4为本实用新型所用的销钉示意图；
图5为传统技术的髋关节柄结构示意图。
如图1至图4所示，图1是本实用新型一个较佳实施例组合式人工髓关节柄20结构示意图，它由一块与人体股骨大转子与小转子间骨髓腔形状吻合的金属块1、一块由同类金属制作的金属片2及一根与金属块以螺纹状结构3紧密结合的同类材料的金属棒4组合成。金属块1上邻近大转子方向之两面均有一可镶嵌式凹槽5，凹槽5四周边缘倾斜向外扩张成边槽6，此向外扩张之边槽6与金属片2形成相互紧嵌之机制，且金属片2与凹槽5上有相对应之嵌孔7，可供以生物适应性之销钉8钉入以固定金属片，使无法滑动。与骨髓腔吻合之金属块1和同类材料之金属棒4由螺纹状结构3紧密结合，形成一完整的人工髋关节柄，其尺寸大小可应市场需求交替搭配，库存量小，成本低。金属片2可在金属块1之两面均以上述机构嵌入，且其表面可涂布制作成不同可诱使人体骨骼生长的材料或结构，而达到可变型式人工髋关节柄在人体手术之股骨髓腔内形成固定之作用，且不同表面处理之金属片可交互更换，适应各类髋关节病症之需求。金属片表面涂布的材料根据临床需要，可以是羟基磷灰石、珍珠面、金属丝面或骨水泥。本实用新型的髓关节柄各部位扭力、抗压力均符合生物力学原理。
