Instrument set for percutaneous spine stabilization using pedicle screws and rods

摘要

The invention relates to a set of instruments for percutaneous spine stabilization with the aid of rods (8) and a screw head (3) and a screw shank (4) having pedicle screws (1) with a distal open recess (13) for receiving a rod (8) a cylindrical sleeve (20) and a slide (24) comprising screw manipulator (2), wherein - the wall of the cylindrical sleeve (20) of two diametrically opposed, axially extending and in the proximal The proximal ends of the first wall segments (27) form gripping elements (28), which in a screw manipulation at least a longitudinal portion of the screw head (3) between take up, and - the slide (24) in the axial direction on the sleeve (20) displaceable and thus with the first wall segments (27) is connected in that it secures it against radial divergence, at least in a proximal displacement end position (E).
