1,、頂端操作簡(jiǎn)單,,長(zhǎng)臂結(jié)構(gòu)有利于棒的植入
Easy-to-operate top coupled with long Tail makes it easy to implant
2,、內(nèi)鎖螺母,,雙重鎖定
Inward-locking screw bolt for enhanced locking effect
3、萬(wàn)向螺釘能提供較大角度范圍的連接鎖緊
Polyaxial screws provide locking within a wide angle range
4,、螺母為獨(dú)特的梯形螺紋可將螺紋的外張力降到最低,,防止釘臂張開(kāi)變形
Unique trapezoidal thread design minimizes external tensionand prevents deformation
5,、梯形螺紋可增強(qiáng)摩擦力,阻止螺母松動(dòng)確保光棒固定安全可靠
Trapezoidal thread design increases friction to preventloosening and ensure tight fixation.
6,、頂絲有利于進(jìn)一步消除螺紋間隙,,增加鎖緊壓力
Tip wire reduces gaps among the threads and increases locking pressure
