Fasteners TRIZ Cases
- Patella Bone Plate with Mesh Cage for Fracture Fixation
Segmented mesh cage fixation stabilizes comminuted inferior poles while preserving the patellar vascular supply.
- Surgical Shim K-Wire Guide and Barb Stabilization
Segmented guides and barbed features stabilize retractors by preventing corridor intrusion.
- Double-threaded bone screw with segmented anchoring profiles
Segmenting the anchoring body into distinct pitch zones matches cortical and spongy bone hardness to improve holding power.
- Self-Tapping Orthopedic Fixator for Resource-Limited Fracture Care
A modular external fixator with self-tapping bone screws enables rapid assembly and stable fracture immobilization without specialized surgical tools.
- Curved Fracture Plate Oblique Screw Trajectories
A curved fracture plate design positions screw holes with oblique trajectories to enhance fixation strength in the humeral head.
- Spinal Screw Movable Tip Bi-Cortical Fixation
A spinal screw features a sliding distal tip that extends within the shaft lumen to engage bone cortex.
- Elongated Pin with Threaded Conical End for Bone Fixation
A threaded conical pin anchors in cortical bone to balance system weight and fixation stability while reducing infection risk from invasive procedures.
- Half Pins for External Fixators with Hydroxyapatite Coating
A half pin uses a thin hydroxyapatite coating and variable thread pitch to stimulate bone growth.
