Abstract

本实用新型公开了一种人工髋关节假体,所述假体的关节端的外表面上设有若干微孔。采用上述结构后,由于假体的关节端外表面上设有若干微孔,使假体植入人体后,人体骨组织长入微孔中从而跟假体连接牢固;另外,由于微孔深度为200-400微米,微孔间距为50-500微米,微孔孔径为50-500微米,从而保证微孔加工方便、骨组织长入效果好,进一步保证假体与人体连接牢固、稳定性好,延长人工髋关节假体的使用寿命。

Description

人工髋关节假体
技术领域
本实用新型涉及一种人工髋关节假体,属于医疗器械技术领域。
背景技术
人工髋关节假体在植入人体后,常因假体表层与人体骨组织之间结合不好而使连接不牢固,导致假体在人体内的稳定性差、使用寿命短。
实用新型内容
针对上述问题,本实用新型的目的在于提供一种与人体骨组织连接紧密、手术时使用更加方便的人工髋关节假体。
为达到上述目的,本实用新型的技术解决方案为:
一种人工髋关节假体,所述假体的关节端的外表面上设有若干微孔。
进一步,所述微孔深度为200-400微米。
进一步,所述微孔间距为50-500微米。
进一步,所述微孔孔径为50-500微米。
进一步,所述假体的直线端为圆锥形。
进一步,所述直线端的两侧面设有和该直线端延伸方向平行的狭长凹槽。
进一步,所述微孔深度不同。
采用上述结构后,由于假体的关节端外表面上设有若干微孔,使假体植入人体后,人体骨组织长入微孔中从而跟假体连接牢固;另外,由于微孔深度为200-400微米,微孔间距为50-500微米,微孔孔径为50-500微米,从而保证微孔加工方便、骨组织长入效果好,进一步保证假体与人体连接牢固、稳定性好,延长人工髋关节假体的使用寿命。
附图说明
图1为本实用新型的结构示意图;
图2为本实用新型另一实施例的结构示意图。
具体实施方式:
如图1所示,本实用新型人工髋关节假体,包括关节端1及直线端2,关节端1的外表面上设有若干微孔11,微孔11可根据需要设为规则或不规则图案,如图1、2所示,微孔11的深度为200-400微米,微孔间距为50-500微米,孔径为50-500微米;直线端2为圆锥形,手术时可方便地将假体植入人体股骨髓腔中。并且,直线端2的两侧面设有和该直线端延伸方向平行的狭长凹槽21,在假体插入股骨髓腔时该凹槽起到排出骨髓和血液,减低髓腔压力的作用。
另外,关节端1的外表面上若干微孔11的深度还可选取不同值。
