摘要: A spinal implant that has a rod connects and stabilizes the vertebrae of vertebral column. The screws are attached to vertebrae. Each screw clamp with first bore allows be placed over screw. is larger than major diameter screw, so can float about screws. clamps each have second perpendicular bore, adapted receive hold rod. Integrally formed pair flanges. When flanges deflected inward, "grabs" on hexagonally shaped shoulder nut fastened onto opposite side clamp, such pressed between nut. approximately same small deflection produces large clamping force
