Bone Implant TRIZ Cases

A porous ceramic bone substitute material uses a polyurethane foam template to create an open-pore structure for osseoconduction.

A mitral valve implant anchors to coronary tissue via a shaft to restore proper heart function.

Microgrooved titanium surfaces with TiN deposition anchor PCL nanofibers to prevent detachment and boost osseointegration.

Integrated keels on the spacer anchor into vertebrae, eliminating supplemental screws and reducing surgery time.

Physical vapor deposition creates a uniform tantalum layer that prevents stress shielding and promotes vascularization.

Segmented cutting rib assembly allows instant swapping of worn components, preventing cross-contamination and thermal osteonecrosis during bone reaming.

A percutaneous implant uses a porous spigot to promote tissue ingrowth and secure external prostheses.

A layered ceramic structure enhances surface hardness on zirconium alloy substrates.

A subperiosteal syringe device delivers bone graft material through soft tissue tunnels to precise surgical sites.

Removable shield retains bone graft material inside interbody implant during insertion, preventing heterotopic bone formation from leakage.

Folded biocompatible fabric prosthesis resists buckling under compressive forces during implantation.

Composite polyurethane particles in a curable binder resolve the trade-off between pore interconnectivity and mechanical strength.

Offset drill guide transfers pre-measured distances to bone, resolving visibility and precision trade-offs during surgical graft placement.

Segmented spline teeth invert complex threading to simplify locking, reducing surgical time while maintaining high primary stability.

Dynamic bioactive bone graft materials replace donor site morbidity by providing customizable, moldable synthetic implants with controlled porosity.

A nested hollow tube delivers bone graft material into a disc space while positioning a fusion cage, reducing surgical trauma.
