Claims20
A screw lock for a cervical plate assembly, the screw lock comprising:
- a first screw locking edge at a first end of the screw lock and a second screw locking edge at a second end of the screw lock, wherein each of the screw locking edges has an outer side edge and an inner side edge opposite the outer side edge;
- a compliant middle section comprising a first linking member and a second linking member that extend between the inner side edge of the first locking edge and the inner side edge of the second locking edge;
- and
- one or binding members connecting the first and second linking members, wherein each of the one or more binding members are spaced along the linking members between the inner side edge of the first screw locking edge and the inner side edge of the second screw locking edge.

- a first screw locking edge at a first end of the screw lock and a second screw locking edge at a second end of the screw lock, wherein each of the screw locking edges has an outer side edge and an inner side edge opposite the outer side edge;
- a compliant middle section comprising a first linking member and a second linking member extending between the inner side edge of the first locking edge and the inner side edge of the second locking edge;
- and
- a first pair of plate stop tabs formed where the linking members attach to the first screw locking edge and a second pair of plate stop tabs formed where the linking members attach to the second screw locking edge, wherein each plate stop tab of the first and second pairs of plate stop tabs has a distal end extending perpendicularly relative to a medial line of the screw lock, the medial line being perpendicular to the first and second screw locking edges.

- a compliant middle section comprising a first linking member and a second linking member that extend between the inner side edge of the first locking edge and the inner side edge of the second locking edge, wherein each of the linking members is serpentine with one or more inward bends that extend toward a medial line of the screw lock body that is perpendicular to the first and second screw locking edges;
- one or binding members connecting the first and second linking members, wherein each of the one or more binding members are spaced along the linking members between the inner side edge of the first screw locking edge and the inner side edge of the second screw locking edge;
- and
- a first pair of plate stop tabs formed where the linking members attach to the first screw locking edge and a second pair of plate stop tabs formed where the linking members attach to the second screw locking edge, wherein each plate stop tab of the first and second pairs of plate stop tabs has a distal end extending perpendicularly away from the medial line.
