The Intervertebral Fusion Cages Torsion Fatigue Tester is a specialized biomechanical testing device used to evaluate the torsional fatigue performance of spinal fusion cages. It simulates the twisting forces that implants experience in the human spine during daily movement, assessing their durability, structural integrity, and long-term reliability.
Standard
(1)YY/T 0959-2014 (China): Specifies torsional fatigue testing protocols for intervertebral fusion devices, including load ratios, frequency, and failure criteria.
(2)ASTM F2077-17 (International): Defines methodologies for evaluating the fatigue strength of intervertebral body fusion devices under torsional loading.
(3)ISO 12189-1: Additional compliance for mechanical testing of spinal implant components.
Application
The Intervertebral Fusion Cages Torsion Fatigue Tester is used to assess the mechanical durability and torsional fatigue resistance of spinal fusion cages under repeated twisting loads. It helps manufacturers and researchers evaluate implant performance, predict long-term reliability, and ensure compliance with biomechanical testing standards before clinical implementation.
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.
