Description

一种股骨柄假体
技术领域
本实用新型涉及一种股骨柄假体，尤其涉及一种结构稳定性强、生物相容性高、节省成本的股骨柄假体。
背景技术
现有的股骨柄假体存在结构稳定性不强的缺点，难以固定或固位不稳，股骨柄与骨质之间容易发生松动，而且股骨承受重力难以均衡，容易造成股骨柄损坏，缩短了股骨柄的使用寿命，增加了股骨柄的更换率和治疗成本。
实用新型内容
针对现有技术存在的上述缺陷，本实用新型旨在提供一种结构稳定性强、生物相容性高、节省成本的股骨柄假体。
为了实现上述目的，本实用新型采用以下技术方案：股骨柄假体包括柄体、颈领和球关节；所述柄体和所述颈领为活动连接，所述柄体和所述颈领连接处设有球关节；所述颈领上设有螺丝钉；所述柄体上设有多孔钽填充部位。
    作为对本技术方案的改进，所述多孔钽填充部位为方孔状。
与现有技术比较，本实用新型由于采用了上述技术方案，增强了股骨柄假体的结构稳定性，提高了股骨柄假体的生物相容性，节省了治疗成本。
附图说明
图1为本实用新型实施例的结构示意图。
图中：1柄体、2颈领、3球关节、4螺丝钉、5多孔钽填充部位。
具体实施方式              
下面通过实施例对本实用新型进行具体的描述，有必要在此指出的是以下实施例只用于对本实用新型进行进一步的说明，不能理解为对本实用新型保护范围的限制，本领域的技术人员可以根据上述内容对本实用新型作出一些非本质的改进和调整。
实施例：一种股骨柄假体，如图1所示，股骨柄假体包括柄体1、颈领2和球关节3；所述柄体1和所述颈领2为活动连接，所述柄体1和所述颈领2连接处设有球关节3；所述颈领2上设有螺丝钉4；所述柄体1上设有多孔钽填充部位5。
优选地，所述多孔钽填充部位5为方孔状。
使用时，柄体与颈领连接处设有球关节，柄体与颈领通过球关节活动连接。螺丝钉有助于提高结构的连接稳定性。多孔钽填充部位能有效提高结构的生物相容性，加强结构的稳定性。这种结构的股骨柄假体，结构简单紧凑，连接可靠，固位稳定，不仅可以使股骨柄与股骨相对固定，而且使股骨承受的重力均衡分布，可有效防止股骨柄和骨质间发生松动，使结构不易损坏，延长股骨柄的使用寿命，节省治疗成本。
