Bone Implant TRIZ Cases
- Intervertebral Implant with Extendable Bone Fixation Members
Extendable staples engage vertebral bodies via cam mechanisms, resolving the trade-off between secure attachment and insertion complexity.
- Biologic Injection System with Planetary Gear and Pressure Limiting
A medical compound delivery device uses a planetary gear assembly to move a dispensing element in discrete increments through a flexible conduit.
- Segmented Bone Substitute Scaffolds for Cavity Adaptation
Segmented structural elements with varying hardness fill irregular bone cavities, resolving the trade-off between complete filling and mechanical stability.
- Spinal Fusion Device with Dynamic Expansion and Hollow Shaft
Dynamic expansion mechanism transitions from compact insertion to expanded state, resolving structural reliability issues while enabling material injection.
- Composite Bone Implant Merging Osteoinductive and Osteoconductive Functions
A composite bone implant merges polylactic acid scaffolds with allogenic bone material to create a customizable structural support.
- Resilient Plug for Osteolytic Lesion Containment
A resilient plug seals bone lesions to contain osteoregenerative material during injection.
- Allograft Preparation Station with Adjustable Gripping and Cutting Guide
Adjustable internal blocks grip donor bones while a cutting guide directs extraction for single-handed operation.
- Osteoimplant Shape Retention via Porous Composite Structure
Porous ceramic particles bound in a matrix absorb fluids to maintain shape, resolving erosion risks during bone repair procedures.
- Bioimplant Silver-Infused Coating Sustained Ion Release
Calcium phosphate thermal spray films containing 0.05 to 3.00 wt% silver sustain ion release to prevent post-operative biofilm infections.
- Zero-Profile Spinal Cage with Lateral H-Fixation
H-shaped fixation frame extends laterally from a recessed spacer to anchor vertebral bodies without anterior protrusion.
- Expandable Vertebral Implant with Adjustable Screw Mechanism
Adjustable height mechanism resolves anatomical variability by dynamically expanding the spacer while maintaining structural stability.
- Lateral Lumbar Fusion Cage with Asymmetric Fixation
A lateral lumbar interbody fusion cage uses asymmetric fixing nails to restore vertebral alignment and spacing.
- Shoulder Prosthesis Glenoid Component with Perimeter Fins
Perimeter fins on a shoulder prosthesis keel block rotation and encourage bone growth to fix eccentric forces.
- Humeral Head Trialing Assembly with Sliding Adapter Plate
A trialing assembly couples a mounting plate to an adapter coupling plate via a sliding fastener for precise prosthetic head sizing.
- Cartilage Grafts with Subchondral Channels for Recellularization
A devitalized cartilage graft incorporates subchondral channels to facilitate in vitro recellularization and host tissue integration.
- Porous Fusion Device Lattice Structure for Tissue Integration
A porous fusion device uses an internal lattice cage to distribute graft material through variable density structures.
- Spinal Fusion Device Segmented Retention and Load Bearing
Segmented spinal fusion device couples a retention component to a load bearing cage for stable vertebral fixation.
