    • The present invention provides for a screw and rod fixation assembly for fixing a screw and, optionally, a rod. The screw and rod fixation assembly includes a screw, fixing mechanism, a substantially annular ring, rod seating mechanism, and locking mechanism. The present invention also provides for a fixing mechanism for fixing a screw, wherein the fixing mechanism further includes an inner surface wall having a gripping portion and a non-gripping portion. Further, the present invention provides for a substantially annular ring for guiding and providing mechanical and frictional force to a screw head. Additionally, the present invention provides for a rod seating mechanism operatively engaged to the screw head and including at least one flexible portion capable of being compressed against a portion of a rod therein. Finally, the present invention provides for a locking mechanism for engaging the rod and the rod seating mechanism. The locking mechanism includes a deflecting mechanism for deflecting the at least one flexible portion of the rod seating mechanism against and around the rod as the locking mechanism further engages the at least one flexible portion of the rod seating mechanism.
    • 本发明提供一种用于固定螺钉和任选的杆的螺钉和杆固定组件。 螺杆和杆固定组件包括螺钉,固定机构,基本环形的环,杆座机构和锁定机构。 本发明还提供了一种用于固定螺钉的固定机构,其中固定机构还包括具有抓握部分和非抓握部分的内表面壁。 此外,本发明提供了一种用于引导并向螺钉头提供机械和摩擦力的大致环形的环。 另外,本发明提供了一种可操作地接合到螺钉头并且包括至少一个柔性部分的杆座机构,该柔性部分能够抵抗杆的一部分被压缩。 最后,本发明提供了用于接合杆和杆座机构的锁定机构。 所述锁定机构包括偏转机构,用于当所述锁定机构进一步接合所述杆座机构的所述至少一个柔性部分时,使所述杆座机构的所述至少一个柔性部分偏转和围绕所述杆。

    • A screw and rod fixation assembly includes a body member including a screw seat for seating a screw head therein and a rod seat for seating a rod therein. An adjustable locking ring applies a locking force against the screw head seated in the screw seat and a locking cap adjustably applies a locking force against a rod seated in the rod seat. The adjustable screw locking ring and locking cap function independent of each other. A method of fixing the rod to the screw includes the steps of inserting a screw head into a screw seat in one end of a body member and inserting a rod into a rod seat in a second end of a body member and selectively and independently adjusting a locking force on both the screw head and the rod within the screw seat and rod seat, respectively.
    • 螺钉和杆固定组件包括主体构件和杆座,主体构件包括用于在其中放置螺钉头的螺钉座和用于将杆放置在其中的杆座。 可调节的锁定环对位于螺钉座中的螺钉头施加锁定力,并且锁定帽可调节地将锁定力施加到坐在杆座中的杆上。 可调式螺丝锁定环和锁定盖彼此独立工作。 将杆固定到螺钉上的方法包括以下步骤:将螺钉头插入本体构件的一端中的螺钉座中,并将杆插入本体构件的第二端中的杆座中,并选择性地且独立地调节 锁定力分别在螺丝座和杆座内的螺丝头和杆上。
