Fasteners TRIZ Cases
- Shape Memory Compression Screw for Orthopedic Fixation
A Nitinol compression screw maintains prolonged compressive load across fracture sites using elastic energy storage.
- Self-adjustable Pectus Reconstruction Bar with Sliding Slots
Sliding slots in the reconstruction bar enable dynamic adjustment for respiratory changes, reducing pain from rigid implants.
- Bone Implant Screw Wedging via Conical Head and Radial Notch
Radial notches in the implantable part allow multi-directional screw insertion while conical geometry prevents unscrewing.
- Variable Angle Bone Fixation Device Burr Prevention
Dulled plate hole edges prevent burr formation during variable angle screw locking, maintaining structural stability.
- Superelastic Screw Bone Plate Dynamic Compression
Superelastic screws provide dynamic biasing force for controlled fracture compression, resolving rigidity constraints in orthopedic fixation.
- Bone Fixation Plate With Positioning Pin And Temporary Wire
A bone fixation plate with distinct apertures guides a temporary wire through a positioning pin, enabling accurate alignment before permanent screw insertion.
- External Knee Load Bearing Distracting Device
Rotatable extensions and translational inserts unload knee cartilage while maintaining physiological range of motion for osteoarthritis treatment.
- Independent Rotation Bone Screw for Locking and Lagging
Segmented head and shaft rotate independently to lock the plate while lagging the bone, resolving fixation stability versus anatomical reduction trade-offs.
- Orthopedic Screw Thread Ribbon Resilient Flange
A resilient flange portion on the thread ribbon expands radially to increase outer diameter under load.
- Bone Fusion Plate with Countersunk Screw Holes for Hallux Valgus
A bone fusion plate stabilizes the first metatarsal head and shaft during osteotomy.
