Ligaments TRIZ Cases
- Flipping-Type Graft Fixation Device with Sliding Loop
A sliding graft retention loop moves to a midpoint position on the fixation buckle to minimize flipping distance.
- Surgical Ligament Reconstruction Sleeve with Bone Regrowth
Intermediary sleeve mimics natural ligament environment to resolve anatomical reconstruction accuracy and fixation stability trade-offs.
- Forked Graft Introducer with Tensioned Suture for Bone Tunnel Insertion
A forked graft introducer spans a suture between tines to position tendon tissue within a bone tunnel, preventing frictional displacement during insertion.
- Continuous Artificial Muscle Fiber Twisting via Localized Heating
Localized heating softens artificial muscle fibers during continuous twisting, preventing snarls and breakage while enabling large-scale production.
- Hemi-Collateral Ligament Graft for Small Joint Repair
Segmenting collateral ligaments into hemi-grafts eliminates donor site morbidity while matching material properties for small joint reconstruction.
- ACL-Substituting Knee Prosthesis Post Design
Integrated tibial post substitutes ACL function to maintain normal motion patterns without requiring separate reconstruction surgery.
- Hardenable Filler Anchoring Graft to Bone via Expansion
A hardenable filler material expands within a bone cavity to secure a graft against the walls.
- Implantable Prosthesis Buckling Prevention via 3D Reinforcement
A composite prosthesis employs a three-dimensional reinforcing element to prevent central buckling and viscera exposure when pulling forces are applied.
- Tenodesis Implant With Push Rod Guide For Accurate Tendon Fixation
A tenodesis implant uses a push rod to guide tendon placement into a bone bore for secure anchoring.
- Canine Tibial Osteotomy Surgical Guidance System
Surgical guidance system aligns canine tibia via precise osteotomy, reducing shear forces and joint instability.
- Variable Stiffness Device Using Granular Jamming
Granular medium compression against an outer member increases structural rigidity while maintaining contour adaptability for rehabilitation support.
- Elongate Fiber Artificial Muscles for Scalable Actuation
Elongate fiber artificial muscles replace expensive nanotubes with coated commercial fibers, achieving high tensile strength and scalability.
- Trochlear Implant Oval Stem Design for Cartilage Repair
Oval stem trochlear implant abuts prepared bone surfaces to repair articular cartilage defects.
- In Situ Graft Tensioning for Knee Ligament Reconstruction
Simultaneous heating and tensioning maintains graft size, preventing unpredictable shrinkage and hyperextension.
- Elevated Meniscus Implant Anchorage Design
An elevated meniscus implant integrates anchoring protrusions directly into its outer surface structure.
- Biceps Tenodesis Delivery Tool with Segmented Anchor and Fork
A tendon anchoring system uses a segmented anchor delivered by a universal fork tool to simplify surgical placement.
- Resilient Multi-Axial Ankle Foot Prosthesis for Gait Stability
Segmented stiffness in the ankle member balances heel strike stability with progressive toe-off support, resolving multiaxial movement trade-offs.
- Trephine System for Ligament Reconstruction with Sliding Support Stem
A concentric trephine system uses a sliding reamer support stem to harvest bone tunnels accurately.
