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

Bidirectional Torsion Control: Advanced electromagnetic actuator maintains R=-1 load ratio (fully reversed torsion) with ±0.1% accuracy.

5 Million Cycle Endurance: Proven capability to complete YY/T 0959’s 5×10⁶-cycle fatigue test without calibration drift.

Dynamic Angle Control: 0.001° resolution ensures precise replication of physiological spinal motion.

Real-Time Fracture Detection: AI-powered acoustic emission monitoring identifies micro-cracks at sub-millisecond intervals.

Intuitive Workflow: 21.5” capacitive touchscreen with gesture control and pre-loaded SOPs for 8+ implant geometries.

Modular Environmental Chambers: Quick-swap pods for simulated physiological (-20°C to +50°C) and corrosive environment testing.

Product Features

Electromagnetic Servo Motor: 50 Nm peak torque capacity with programmable load ratios (R=-1 to R=0.1).

Torsional Actuator: ±180° rotation range with 0.001° angular resolution.

Dynamic Load Control: 0.1–5 Hz frequency range with programmable waveforms (sine, square, random, custom).

Thermal-Mechanical Chamber: ±0.3°C temperature stability with integrated humidity control (10–95% RH).

High-Speed Imaging Ready: Syncs with external cameras for full-field strain mapping (DIC optional upgrade).

Safety First: Triple-redundant emergency stop, overload clutches, and laser-based specimen breakage detection.
