Internal Osteosythesis TRIZ Cases
- Polyaxial Spinal Rod Connectors for Non-Parallel Alignment
This case uses adjustable passages, set screws, and rod cradles to secure spinal fixation rods at angles up to 40 degrees.
- Dynamic Compression Fixation for Bone Alignment and Remodeling
Dynamic compression fixation adapts from initial stabilization to later bone remodeling, helping maintain alignment during healing.
- Monolithic Variable-Diameter Spinal Rods to Reduce Stress Shielding
A monolithic spinal rod uses smooth diameter transitions to tailor stiffness, reduce stress shielding, and support flexible screw placement.
- Nested Screw Assembly for Simultaneous Bone Compression and Stability
A cannulated outer screw and inner screw work together to compress a joint while maintaining fixation stability.
- Rib Fracture Fixation Using Minimally Invasive Intramedullary Stents
Guidewires and catheters deliver an expandable intramedullary stent to realign and stabilize difficult rib fractures.
- Spinal Fusion Plate Guide Assembly for Precise Screw Placement
Preconfigured guide bores and a plate holder support precise spinal fixation, helping reduce parts, surgical time, and placement risk.
- Spinal Stabilization Anchors and Bridges Restraining Segmental Motion
This case uses clamps, bridges, and tracking markers to stabilize vertebrae and improve surgical tool guidance.
