Fasteners TRIZ Cases
- Intraoral Surgical Guide Fixation With Replaceable Pins and Drill Sleeves
Larger replacement pins and guiding sleeves address loosening and drill wandering during intraoral guided surgery.
- Surgical Screw Caddy With Elastomeric Stabilization for Insertion
A screw caddy uses elastomeric openings and a rigid handle to limit dislodgement during plate and patient insertion.
- Surgical Bone Rivet With Expandable Shaft for Rotation-Free Fixation
A deformable threaded shaft expands with a mandrel for linear bone fixation, while a cutting flute eases later removal.
- Minimally Invasive Bone Fixation Tool With Deployable Retention Block
A displacement tip, retention block, and targeting guide support precise fixation through one wound, reducing repeated insertions and recovery burden.
- Variable-Angle Locking Construct With Relief Holes for Orthopedic Plates
A tapered-head anchor and relief-hole plate support variable-angle locking, reliable load transfer, and reduced screw backout.
- Guidewire-Capturing Instrument for Single-Step Pedicle Screw Insertion
An integrated handle, wire housing, and clutch reduce instrument switching, guidewire handling, and infection risk during insertion.
- Bendable Orthopedic Fasteners With Helical Flexure and Torque Drivers
This case shows how helical openings and interior torque drivers help orthopedic fasteners bend while transmitting driving torque.
- Variable-Pitch Surgical Screw for Combined Compression and Locking
A variable-pitch shaft and matching head thread combine fracture compression and bone-plate locking in one surgical screw.
- Extremity Fusion Plate Assembly With Screw-Guided K-Wire Alignment
A bone plate, screw guide, and K-wire coordinate fixation and alignment to support stable extremity bone fusion and weight bearing.
