Spinal Implants TRIZ Cases

A hinged artificial spinal disk uses a sliding rod to enable multi-dimensional motion within controlled limits.

Bi-concave core elements articulate with convex end plates to provide universal motion and horizontal translation while preserving spinal stability.

Segmented main body and movable frame generate complementary acting forces to improve engagement stability and expedite bone fusion.

Linked locking elements mechanically secure an expandable spinal cage, resolving the trade-off between ease of insertion and interface stability.
