Osteosynthesis Devices TRIZ Cases
- Ultrasonic Cement Removal Tool with Helical Dimples
Helical dimples on the shaft convert longitudinal vibrations to torsional motion, softening cement and reducing bone damage risk during revision arthroplasty.
- Surgical Breaking Tool for Cured Bone Cement Removal
A surgical breaking tool with a nose and chisel removes cured bone cement using human power.
- Bone Stabilization Apparatus for Accurate Orthopedic Reaming
Nested sleeves and interlocking rods stabilize bone elements, resolving the trade-off between positioning accuracy and device complexity.
- Angled Bone Screw Extraction Device with V-Groove Tip
Segmented handle and arm apply dynamic force through a cutting V-groove to extract lost-purchase screws while protecting surrounding bone tissue.
- Electric Orthopedic Impactor Tool with Rotary-to-Linear Mechanism
An electric orthopedic impactor tool uses a motor and rotary-to-linear conversion mechanism to drive a piston for controlled bone preparation.
- Spring-Locked Bone Milling Cutter for Easy Blade Replacement
Integrating a spring locking mechanism reduces part count and simplifies cleaning while enabling quick blade replacement.
- Bone Cement Cure Monitoring via Acoustic Resonance Shift
Acoustic resonance monitoring replaces subjective palpation with quantitative viscosity tracking for precise surgical timing.
