Description
本实用新型属假肢体或附件领域，具体涉及一种新型人工髌骨关节。
骨损伤、化脓性骨髓炎、化脓性关节炎等疾病严重地影响着患者的身体健康，给患者带来极大的痛苦。急慢性骨髓炎、关节炎，例如膝关节炎早期表现为红、肿、痛、热、关节肿痛、活动受限，严重者将累及关节骨质损伤，甚者需要截肢才能挽救生命。以往需手术的病人在治疗时将膝关节的整块髌骨换掉。这样，没有病变的骨质也被去除，本实用新型技术方案：
使用Co－Cr－Mo合金材料或钛合金材料，整体精铸，再将钉子焊上，根据病人病情及骨骼大小，骰骨髁可分不同大小，宽为50～60mm，高40～50mm，厚5.5～8mm，钉子用普通车床加工成塔形，钉子长15～30mm。人工髌骨加工成大小为直径25～35mm，高10～20mm，钉子长8～15mm。在髌骨内面上对称分布有椭圆形孔，以利于骨质生长。股骨髁与人工髌骨共同组合为人工髌骨关节。手术时，将人工骰骨髁替代坏死骨质，钉入股骨，用人工髌骨替代坏死的髌骨钉入胫骨，手术后缝合即可。
使用人工髌骨关节有如下优点：1、对病人损伤小。可根据病人骨损伤的情况，选用大小不同型号的骰骨髁，只要切除患病部分，不需全切除。2、减少病人痛苦。因手术范围减小，只施行部分切除，手术工作量小，简单，时间短，病人少受痛苦。3、便于推广。由于手术简化，使用器械少，医生易于掌握，中小医院也可手术，方便病人。4、节省了医疗费用与医疗材料。5、经临床观察，疗效与全切除一致。6、钉子加工成塔形，不易脱落，固定效果好。
本实用新型有如下附图：
图1 为人工髌骨关节主视图；
图2 为骰内髁俯视图；
图3 为骰骨髁侧视图；
图4 为人工髌骨底视图。
实施例：见图1、图2、图3、图4。使用Co－Cr－Mo合金材料，整体精铸，打磨抛光，骰骨髁1长56mm，宽42mm，厚6.5mm，钉子2长20mm，两钉间距为32mm，钉子2加工成塔形状。人工髌骨3直径为30mm，钉子4直径为10mm，钉子4长10mm，加工成螺丝形状，人工髌骨3总高为14mm，其内面有六个椭圆形孔5。手术时，将人工骰骨髁替代坏死骨质，用人工髌骨替代坏死的髌骨，分别钉入股骨和胫骨，然后手术缝合，愈合后即可。
