Bone Implant TRIZ Cases

Aseptic processing preserves osteoinductivity while enzymatic extraction removes collagen to eliminate immunogenic reactions.

A helical bone graft containment device expands to fill irregular target spaces while retaining graft material.

Computed tomography generates accurate bone parameters for implant cutting plans, eliminating destructive testing and clean room waste.

Slits in the housing allow thread protrusion, providing resistance to migration and pull-out during bone fixation.

A cannulated sacroiliac screw uses a self-drilling tip and spiral cutting flutes to advance into bone.

A bone anchor with a cutting distal tip enables rapid insertion into bone tissue.

Segmented annular and leaflet support members prevent mitral valve prolapse without invasive resection, improving coaptation reliability.

Elastic hinges enable the foldable spinal implant to self-deploy, resolving subsidence risks and complex mechanical expansion.

Segmented intervertebral prosthetic discs use posterior endplates and cores to reduce surgical exposure size and avoid anterior vascular injury.

A contoured patella spacer implant uses fluid-filled bladders to redistribute joint forces and maintain tendon alignment.

Integrated spin-plate eliminates separate fixation devices, resolving surgical complexity while maintaining reliable vertebral stability.

A bone fiber processing apparatus produces heterogeneous allograft fibers with varying dimensions to enhance cellular infiltration.

Asymmetric biplanar geometry allows straight diagonal insertion of a fusion cage, eliminating blind rotation and ensuring flush vertebral contact.
