Total Knee Joint Prostheses Wear Tester - China

Standard

ISO 14243-1: 2014: Specifies wear testing parameters for total knee prostheses, including axial loading, flexion/extension kinematics, and environmental conditions.

ISO 14243-3: 2014: Defines protocols for simulating physiological loading, displacement, and rotation during knee joint wear testing.

ASTM F3297-18: Additional compliance for advanced testing scenarios including high-flexion and pivot-shift motions.

Product Advantages

Hexapod Motion Control: 6-DOF kinematic simulation replicates natural knee motion (flexion/extension ±120°, AP displacement ±15 mm, tibial rotation ±20°).

Dynamic Load Management: Dual-axis load control (axial 0–3.000 N, shear 0–500 N) with 0.1% force accuracy.

Biorelevant Environment: Temperature-controlled (37±1°C) lubrication bath with 20±2 g/L protein concentration.

Extended Durability: Capable of 10+ million cycle testing with <0.3% drift in calibration.

Automated Compliance: Pre-programmed ISO/ASTM test protocols with real-time data validation.

Modular Design: Four-station configuration allows parallel testing of multiple specimens.

Product Features

Electrohydraulic Actuation: Six independent servo-hydraulic actuators for precise motion control.

6-Axis Force/Torque Sensors: Measure axial forces, shear forces, and torsional moments simultaneously.

Temperature-Controlled Bath: Recirculating lubrication system with protein skimmer and pH 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.
