Total Hip Joint Prostheses Wear Tester
Standard
- YY/T 0651.1-2016 (China): Specifies wear testing parameters for total hip prostheses, including angular motion, loading modes, and environmental conditions.
- ISO 14242-1:2014 (International): Defines protocols for simulating physiological loading and kinematics during hip joint wear testing.
- ASTM F3047M-15: Additional compliance for advanced testing scenarios including edge loading and micro-separation.
Product Advantages
- Triaxial Motion Simulation: Replicates full physiological motion profiles (flexion/extension ±100°, abduction/adduction ±30°, internal/external rotation ±40°).
- Dynamic Load Control: Dual-peak loading up to 4,500 N with 0.1% force accuracy.
- Biorelevant Environment: Temperature-controlled (37±2°C) lubrication bath with 30±2 g/L protein concentration.
- Extended Durability: Capable of 5+ million cycle testing with <0.5% drift in calibration.
- Automated Compliance: Pre-programmed ISO/YYT test protocols with real-time data validation.
- Modular Design: Six-station configuration allows parallel testing of multiple specimens.
Product Features
- Electrohydraulic Actuation: Six independent servo-hydraulic actuators for precise motion control.
- 3D Force/Torque Sensors: Multi-axis sensors measure axial forces and torsional moments simultaneously.
- Temperature-Controlled Bath: Recirculating lubrication system with protein concentration monitoring.
- High-Resolution Imaging: Optional integration with micro-CT systems for in-situ wear analysis.
- AI-Powered Analytics: Machine learning algorithms predict wear rates from initial test cycles.
- Safety System: Emergency stop, over-pressure relief, and laser-based specimen breakage detection.
