    • Disclosed are devices, methods and systems for manipulating a pedicle screw assembly and for inserting and reducing a rod relative to the pedicle screw assembly. The system can include a cannula assembly having a reduction cannula with an internal bore extending between a proximal region and a distal region and an insertion cannula co-axially positioned within the internal bore of the reduction cannula. The insertion cannula includes a pair of opposed prongs extending distally from a distal region of the insertion cannula, wherein each prong is interposed between a pair of flexible projecting elements. The pair of opposed prongs of the insertion cannula and the distal region of the reduction cannula are aligned to collectively define an opening that is sized and shaped for receiving a spinal rod. The device also can include an annular collar mounted on the proximal region of the reduction cannula and rotatably coupled to a proximal region of the insertion cannula. The cannula assembly can also be a pivoting cannula assembly.
    • 公开了用于操纵椎弓根螺钉组件以及用于相对于椎弓根螺钉组件插入和缩小杆的装置,方法和系统。 该系统可以包括套管组件,该套管组件具有减压插管和插入插管,该减压插管具有在近侧区域和远侧区域之间延伸的内孔,该插管同轴定位在减缩套管的内孔内。 插入套管包括从插入套管的远侧区域向远侧延伸的一对相对的叉,其中每个叉插入在一对柔性突出元件之间。 插入套管的一对相对的叉尖和缩小套管的远侧区域对齐以共同限定开口,该开口的尺寸和形状被设计成用于接收脊柱杆。 该装置还可以包括安装在减缩套管的近侧区域上并且可旋转地联接到插入套管的近侧区域的环形套环。 套管组件也可以是枢转套管组件。

    • Disclosed is a spinal transconnector device for coupling longitudinal spinal rods on either side of the mid-sagittal plane. The device includes two interconnected rod engagement elements, a first rod engagement elements having a vaulted surface adapted to secure to a first longitudinal spinal rod via an interference fit comprising compression of the first longitudinal spinal rod against the generally vaulted surface; and an interference pin that advances into a bore of the first rod engagement element forming an interference fit between the interference pin and the rod engagement element. The interference fit can be associated with elastic deformation of the first rod engagement element occurring as a consequence of the interference pin being advanced through the bore in the engagement element and contacting a surface of the first longitudinal spinal rod.
    • 公开了一种用于在中矢状面的任一侧连接纵向脊柱杆的脊柱横切器装置。 所述装置包括两个互连的杆接合元件,第一杆接合元件具有拱形表面,所述拱形表面适于通过过盈配合固定到第一纵向脊柱杆,所述过盈配合包括将第一纵向脊柱杆压靠在通常拱形表面上; 以及干涉销,其进入到所述第一杆接合元件的孔中,形成所述干涉销和所述杆接合元件之间的过盈配合。 干涉配合可以与第一杆接合元件的弹性变形相关联,这是因为干涉销推进通过接合元件中的孔并接触第一纵向脊柱杆的表面。
