SPINAL ROD PERSUADER

机译:螺旋杆说服器

摘要

A spinal rod persuader, system and method can include an outer tube, an inner tube, and a locking element. A first actuation mechanism can be movable in a linear fashion along a longitudinal axis direction to cause the locking element to move in a linear fashion over the inner tube and to lock the inner tube onto a pedicle screw. A second actuation mechanism can be rotated to cause the outer tube to move in a longitudinal axis direction with respect to the inner tube to push the spinal rod into a final position with respect to the pedicle screw while the pedicle screw is locked to the inner tube. A slot and/or tab structure can be provided in the outer tube such that actuation of the slot/tab will allow disassembly of the inner tube, outer tube and locking element with respect to each other.
