Abstract

本实用新型专利为一种骨科髋关节置换手术中的内侧横截面的两条边线成夹角的股骨柄，其特征为在股骨柄的横截面（A-A剖面）上，柄的内侧横截面的两条边线形成5°～179°的夹角。此设计能更多的保留股骨内侧弧形面松质骨，有效保证血液供给。

Description

内侧横截面的两条边线成夹角的股骨柄
技术领域
     本实用新型涉及一种医疗器械中的植入物，特别是一种用于骨科髋关节置换手术中的内侧横截面的两条边线成夹角的股骨柄。
背景技术
在骨科髋关节置换手术中，需要用到股骨柄替代需修复的髋关节，在手术过程中需要去除部分松质骨，形成一个与股骨柄相匹配的型腔。股骨柄（如图1、2）的内侧弧形面（1）与型腔壁压配，形成稳定、可靠的压配关系。由于能更多的保留内侧弧形面松质骨，有效保证血液供给。而常规股骨柄（图3、4）内侧弧形面（1）设计为圆形，不利于保留更多的松质骨，不利骨生长。
发明内容
本实用新型专利针对现有技术的缺陷，提供一种内侧横截面的两条边线成夹角（内侧弧形面扁平）的股骨柄，减少内侧弧形面松质骨的漏失。
附图说明
图1、2为内侧横截面的两条边线成夹角的股骨柄及其横截面示意图；
图3、4为常规股骨柄及其横截面示意图。
具体实施方式
下面结合附图和实施方式对本实用新型作进一步的描述。
如图1、2所示，本实用新型专利为骨科髋关节置换手术中的内侧横截面的两条边线成夹角的股骨柄，其特征为在股骨柄的横截面（A-A剖面）上，柄的内侧横截面的两条边线形成5°～179°的夹角。此设计能更多的保留股骨内侧弧形面松质骨，有效保证血液供给。
