Abstract:
1. A minimally invasive surgical system comprising: a pedicle screw assembly for being connected to a vertebral bone; a coupling member of the pedicle screw assembly for receiving a spinal rod therein; a tubular member adapted to releasably engage the coupling member of the pedicle screw assembly and having a sidewall and an opening extending through the sidewall; a sleeve having an annular wall configured to slide over the tubular member and contact the spinal rod; a fulcrum of the sleeve extending radially outward from the sleeve annular wall; an aperture extending through the sleeve annular wall adjacent the fulcrum and being oriented to allow the sleeve aperture to be at least partially aligned with the tubular member opening when the sleeve is positioned over the tubular member; a lever tool having a distal end portion adapted to fit through the sleeve aperture and at least partially into the tubular member opening to engage the tubular member sidewall adjacent the opening, an intermediate portion adapted to be supported by the fulcrum, and a proximal end portion for applying a force to the lever tool and pivoting the lever tool about the fulcrum for urging the sleeve and spinal rod toward the pedicle screw assembly.
