Intervertebral Fusion Cages Torsion Fatigue Tester

Standard 

• YY/T 0959-2014 (China): Specifies torsional fatigue testing protocols for intervertebral fusion devices, including load ratios, frequency, and failure criteria.
• ASTM F2077-17 (International): Defines methodologies for evaluating the fatigue strength of intervertebral body fusion devices under torsional loading.
• ISO 12189-1: Additional compliance for mechanical testing of spinal implant components.

Product Advantages

1. Bidirectional Torsion Control: Advanced electromagnetic actuator maintains R=-1 load ratio (fully reversed torsion) with ±0.1% accuracy.
2. 5 Million Cycle Endurance: Proven capability to complete YY/T 0959’s 5×10⁶-cycle fatigue test without calibration drift.
3. Dynamic Angle Control: 0.001° resolution ensures precise replication of physiological spinal motion.
4. Real-Time Fracture Detection: AI-powered acoustic emission monitoring identifies micro-cracks at sub-millisecond intervals.
5. Intuitive Workflow: 21.5” capacitive touchscreen with gesture control and pre-loaded SOPs for 8+ implant geometries.
6. Modular Environmental Chambers: Quick-swap pods for simulated physiological (-20°C to +50°C) and corrosive environment testing.

Product Features
