    • The present invention relates to an outrigger for securing a longitudinal spinal rod, preferably a horizontally offset spinal rod, with respect to a bone anchor. The outrigger may include a housing having a first throughbore to receive the bone anchor and a second throughbore to receive the spinal rod, a cam for surrounding the bone anchor, the cam being disposed within the first throughbore, and a collet having a passage for surrounding the spinal rod, the collet being disposed within the second throughbore. The cam may be moveable from a first position to a second position such that, in the first position, the spinal rod and bone anchor are free to move with respect to the housing and in the second position, the spinal rod and collet are secured with respect to the housing. The collet may be moveable between a first configuration to a second configuration such that movement of the cam from the first position to the second position causes the collet to move from the first configuration to the second configuration. The cam preferably may move into contact with the collet when the cam is moved into the second position. The collet preferably may be compressible into the second configuration. The cam may also include an intermediate position wherein in the intermediate position, the spinal rod is free to translate with respect to the housing but is prevented from articulating with respect thereto.
    • 本发明涉及一种用于固定相对于骨锚的纵向脊柱杆,优选水平偏移的脊柱杆的支腿。 外伸支架可以包括具有第一通孔以容纳骨锚的壳体和用于容纳脊柱杆的第二通孔,用于围绕骨锚的凸轮,设置在第一通孔内的凸轮,以及具有用于围绕 脊柱杆,夹头设置在第二通孔内。 凸轮可以从第一位置移动到第二位置,使得在第一位置,脊柱杆和骨锚固件相对于壳体自由移动,并且在第二位置,脊柱杆和夹头用 尊重住房。 夹头可以在第一配置与第二配置之间移动,使得凸轮从第一位置到第二位置的移动使夹头从第一配置移动到第二配置。 当凸轮移动到第二位置时,凸轮优选地可以与夹头接触。 筒夹优选地可压缩成第二构造。 凸轮还可以包括中间位置,其中在中间位置,脊柱杆相对于壳体自由地平移,但是防止其相对于其铰接。

    • An expandable interspinous process spacer implant for insertion and/or implantation between a spinous process of a superior vertebral body and a spinous process of an inferior vertebral body, the implant comprising multiple pairs of legs joined in a scissor-like fashion and pivotally coupled to each other by one or more pins, where each leg has multiple slots along its longitudinal axis. The implant further may include a pair of bearing surfaces coupled between the legs via cross pins and a first plate and second plate each of which is coupled to a pair of roller pins disposed between a pair of slots on the legs where rotation of a fastener in the fastener holes of the first and second plate results in the first plate and the second plate being drawn toward each other causing the expansion of the height of the implant.
    • 一种用于在上椎体的棘突和下椎体的棘突之间插入和/或植入的可扩展的棘突间间隔植入物,所述植入物包括以剪刀状方式连接并可枢转地联接到每个 另一个由一个或多个销钉组成,其中每个支腿沿其纵向轴线具有多个槽。 植入物还可以包括一对通过十字销连接在腿部之间的支承表面,第一板和第二板联接到一对辊销上,该对销钉设置在腿上的一对槽之间, 第一和第二板的紧固件孔导致第一板,并且第二板被拉向彼此,导致植入物的高度的膨胀。
