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