Bone Implant TRIZ Cases
- Expandable Vertebral Implant Gear Mechanism
A coaxial expandable vertebral implant uses a threaded gear mechanism to adjust dimensions for precise spinal fit.
- Hydro-swellable Membrane for Artificial Cartilage Restoration
A polyether-urethane-urea membrane cap absorbs synovial fluid to swell and mimic hyaline cartilage viscoelasticity.
- Entangled Collagen Osteoimplant for Bone Growth
An entangled insoluble collagen fiber matrix forms a semi-solid mass via mechanical force and lyophilization to create a biocompatible implant scaffold.
- Demineralized Bone Gel Sheet Composition for Defect Repair
Autoclaving demineralized bone particles creates a moldable gel sheet that maintains position within osseous defects.
- Reverse Shoulder Prosthesis Glenoid Plate Asymmetry
An asymmetric glenoid plate with a superiorly shifted stem reduces scapular notching and dislocation while increasing range of motion.
- Expandable Implant Tubular Members Key Pin Fixation
Nested tubular members expand via a key pin mechanism to resolve the trade-off between small incision size and structural support while promoting bone growth.
- Polyisobutylmethacrylate Spinal Fill Reduces Polymerization Heat
Replacing PMMA with polyisobutylmethacrylate reduces polymerization temperature, preventing bone necrosis while maintaining structural support.
- Porous Tantalum Coating on Silicon Carbide Template
Chemical vapor deposition coats porous silicon carbide with tantalum metal to create a biocompatible implant material.
- Spinal Fusion Implant Laser-Modified Surface Osteoinductivity
Laser engraving creates nano-scale surface networks on spinal fusion implants to enhance osteoinductive bone growth.
- Spinal Fusion Device Locking Mechanism for Screw Retention
Segmented anchoring and locking fasteners prevent screw disconnection under high stress forces.
- Transcutaneous Prosthetic Anchor and Signal Transmission
A transcutaneous prosthetic device links bone anchors to external limbs via sealed signal transmission means.
- Spinal Interbody Cage with Wide Load-Bearing Footprint
A spinal interbody fusion implant features a wide load-bearing footprint to distribute vertebral loads and enhance structural stability.
- Plasma Arc Sprayed Titanium Coating on Polished Zirconia
Polishing the ceramic substrate before vacuum plasma arc spraying eliminates mechanical interlocking steps while ensuring strong bonding reliability.
- Expandable Spinal Spacer With Graft Window And End-Locking Mechanism
End-mounted locking mechanism enables bone graft insertion into expanded spinal spacers without rotating cage components, preventing vertebral injury.
