Abstract

一种由超高分子量聚乙烯材料制成的新型人造 全髋臼，采用哑铃型粘接结构，使人造骨与骨头粘接 牢固，承受拉力增加三分之二，抗扭力作用增强，可抗 骨水泥老化后松动与脱落，使用时间延长一倍。

Description

本实用新型属于假肢体或附件领域，具体涉及一种新型人造全髋臼。
股骨头坏死、股骨胫骨折，严重骨性关节炎，髋骨骨折等疾病常导致需要手术治疗，去除病灶骨质，换上人工代用骨。在这种情况下，以往的治疗是直接用骨水泥将人造骨与人骨头粘接，其缺点是骨水泥老化后易于松动甚至脱落，承受的拉力也小。近来在接骨时，在骨头与人造骨或人工关节上打孔或挖沟槽，在孔内或沟槽内填上骨水泥后再粘接，形成棒式粘接。这种方法比平面粘接要牢固一些，但仍存在粘接易松动与脱落的缺点，不易锁住，承受的拉力也低。
本实用新型的目的在于提供一种粘接牢固，防止松动脱落的新型人造全髋臼。
技术方案如下：
新型人造全髋臼使用超高分子量聚乙烯材料制造，全髋臼上部为一半球体，直径为38～54mm，半球中空内径为26～32mm，下面有一底座高6～10mm。在半球上交错等距，均匀分布有哑铃型小孔，露在半球表面的孔小，直径为4～8mm，内膛大直径为5～8mm。表面小孔中心间距为10～15mm。哑铃型孔使用三维卡具，用车床加工。使用时，将带哑铃小孔全髋臼孔内压满骨水泥，在对接骨上也对应打上哑铃型小孔，压满骨水泥，吻合对接粘上，待牢固后即完成接骨，然后缝合伤口。
本实用新型的优点在于：由于两骨粘接为哑铃孔式粘接，连接牢固，承受拉力比原来增加三分之二，抗扭力作用增强，可抗骨水泥老化后松动与脱落；使用时间延长一倍。
本实用新型有附图1、附图2。
图1为本实用新型主视图；
图2为本实用新型俯视图。
实施例：见图1、图2。
新型人造全髋臼使用超高分子量聚乙烯材料制成，全髋臼1为半球形，直径为50mm，半球中空，内孔直径为30mm，底座2为8mm，半球面上交错等距，均匀分布打孔，使用三维卡具，车床加工，哑铃型孔3直径为6mm，露在半球表面的孔4直径为4mm，见图2，孔中心间距为12mm。
