Laminoplasty Plate System Fatigue Testing Machine

Standard

• ASTM F2193-18: Specifies static/fatigue testing protocols for spinal constructs, including lamina fixation plates.
• ISO 12189-1: Defines methodologies for evaluating mechanical performance under physiological loading.
• YY/T 0961-2014 (China): Compliance with static/dynamic testing requirements for spinal interconnection systems.
• Custom Protocols: Tailored testing regimens for lamina fixation plate bending/compression fatigue per clinical usage models.

Product Advantages

1. Anatomical Simulation: 4-point bending fixture replicates spinal curvature (0°–45° lordosis adjustment).
2. Dynamic Compression Control: 0.1–15 Hz frequency range with ±0.05% force accuracy.
3. Multi-Axial Loading: Combines axial compression (±25 kN) with anterior-posterior shear (±5 kN).
4. Biorelevant Environment: 37±1°C saline bath with protein skimmer for in vivo corrosion simulation.
5. AI-Powered Analytics: Machine learning identifies creep-fatigue interactions in real-time.
6. Modular Design: Dual-station configuration enables simultaneous specimen testing.

Product Features

• Electromagnetic Servo Actuator: 25 kN axial/5 kN shear capacity with programmable load ratios (R=0.1–10).
• 4-Point Bending Fixture: Self-aligning anvils accommodate plate lengths (30–80 mm) and curvatures.
• Dynamic Load Control: Sinusoidal/square/random waveforms with 0.01 Hz resolution.
• Thermal-Mechanical Chamber: -20°C to +50°C temperature control with 10–95% RH humidity.
• High-Resolution Imaging: Built-in 5MP camera system for crack propagation analysis.
• Safety Suite: Emergency stop, overload clutches, and laser-based specimen breakage detection.
