摘要:
A bone plate locking system including a threaded screw body having a proximal end and a distal end and a plate with a through-hole. The proximal end includes a head. The head includes an upper portion, a groove adjacent the upper portion and a lower portion adjacent the groove, wherein a center-axis of the groove is off-axis to a center- axis of the threaded screw body. A locking ring configured to reside within the groove of the head. The through-hole includes an upper portion, a groove adjacent the upper portion and a lower portion adjacent the groove. The head is receivable in the through- hole. The locking ring is rotatably positioned around the groove of the head such that in an unlocked position the locking ring is outside the groove of the through-hole and in a locked position the locking ring is at least partially within the groove of the through-hole.
摘要(中):
一种骨板锁定系统,包括具有近端和远端的螺纹螺钉主体以及具有通孔的板。 近端包括头部。 头部包括上部,与上部相邻的凹槽和与凹槽相邻的下部,其中凹槽的中心轴线与螺纹螺钉体的中心轴线偏离轴线。 锁环配置成位于头部的凹槽内。 通孔包括上部,与上部相邻的凹槽和与凹槽相邻的下部。 头部可以容纳在通孔中。 锁定环围绕头部的凹槽可旋转地定位,使得在解锁位置中,锁定环位于通孔的凹槽的外部,并且在锁定位置中,锁定环至少部分地位于通孔的凹槽内 。
