1、表面高拋光處理,摩擦系數(shù)極低
Mirror polishing surface reduces friction coefficient to the minimum extent
2,、雙中心設(shè)計(jì)活動保證髖關(guān)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(jīng)典大環(huán)(卡鎖)設(shè)計(jì),良好的防脫位性能
Classic clamping-lock structure avoids head dislocation
