    • One non-limiting embodiment is directed to a reduction instrument releasably engageable with a bone anchor and structured to reduce a connecting element into a receiving member of the bone anchor. The reduction instrument includes a first member and a second member laterally movable relative to the first member between a first position for receiving a portion of the bone anchor and a second position for engaging the reduction instrument with the bone anchor. The reduction instrument also includes an actuating member axially displaceable relative to the first and second members. Additionally, the second member is moved between the first and second positions upon displacement of the actuating member relative to the first and second members, and the second member extends substantially parallel to the first member as it is moved between the first and second positions.
    • 一个非限制性实施例涉及可释放地与骨锚固件接合并且被构造成将连接元件减小到骨锚的接收构件中的减速器。 所述还原器具包括第一构件和第二构件,所述第一构件和第二构件可相对于所述第一构件横向移动在用于接收所述骨锚的一部分的第一位置和用于使所述还原器具与所述骨锚固接合的第二位置。 还原装置还包括相对于第一和第二构件可轴向移动的致动构件。 此外,当致动构件相对于第一和第二构件移动时,第二构件在第一和第二位置之间移动,并且当第二构件在第一和第二位置之间移动时,第二构件基本上平行于第一构件延伸。
