U-Motion II™ 髖臼系統






一杯多襯,滿足所有需求
優磨二代髖臼系統讓骨科醫師可以為需要的病患們選擇最佳的材質配對。




 多樣化的配對組合   
 


理想的球頭與髖臼杯比例,增加關節穩定度
更大的球頭搭配 12/14 的 UTF 軸頭系統,達到滿意的彎曲角度並且沒有碰撞的問題。



 更大的關節活動度    



簡易的襯墊髖臼杯鎖合機制







抗氧化高耐磨聚乙烯全髖臼內襯

聯合抗氧化高耐磨聚乙烯 E-XPETM 提供良好的耐磨特性,展現高機械強度及抗氧化的效果[1-3]


較高的螺絲擺動角度
增進手術的操作彈性,不用為了達到髖臼杯固定度而妥協[4]








具有臨床證明的長期穩定結果







更佳的髖臼杯球頭尺寸配對
使用 56 mm 直徑的髖臼杯就可以搭配 40 mm 直徑的陶瓷球頭,提供更佳的關節穩定度、增進關節活動度,進而減低脫臼的風險。
