1,、表面高拋光處理,摩擦系數極低
Mirror polishing surface reduces friction coefficient to the minimum extent
2、雙中心設計活動保證髖關節(jié)活動范圍最大,,降低磨損率
Two-center design ensures the greatest range of motion and the lowest rate of wear for the hip joint
3,、經典大環(huán)(卡鎖)設計,良好的防脫位性能
Classic clamping-lock structure avoids head dislocation
