Equipment to move loaded with top-loading spinal fixation device and a top-loading spinal fixation device

摘要

The bone anchoring device having a head and a pair of side walls forming the top opening and the top end, a bottom end, is connected to the bottom end, disposed on the top end and the U-shaped elongated groove having a first longitudinal axis system to introduce an elongated spinal rod equipped. The further formed a passage that is configured to receive a spinal rod, and each side wall, a top opening and groove further forms the second end face facing the first end surface, the opposite side of the end surface of the first to. Extends from the bottom end of the head, bone engaging member is secured to the bone the bone fixation device. The system further comprises a tool to be introduced into the U-shaped groove rod. End portion and the tool includes a first member having a proximal end. End portion is configured to guide the rod through the passageway, so as to introduce into the U-shaped groove through the top opening. The second member, to form a second longitudinal axis substantially perpendicular to the longitudinal direction of the first. Has an end and a second end of the first and second end, the second member is disposed outside the passage of the spinal rod, the second member, to the top opening, preferably as there is no possibility of that approach is also interference impedes, I have a pair of jaws is fixed to one of the sidewalls of the head of the bone fixation device tool. The first member, a second end and the first end of the second member so as to introduce a spinal rod passage through the top opening and is a pivotal movement with respect to the second member As is translatable linearly in a direction parallel to the longitudinal axis of the second along a second longitudinal axis between and is connected operatively to the second member.
