Spinal Internal Fixation System Component Testing Machine
Standard
YY/T 0119-2014 (China): Specifies mechanical testing protocols for spinal fixation components, including screws, plates, rods, and connectors.
ASTM F2193-18 (International): Defines methodologies for evaluating the static and fatigue performance of spinal implant constructs.
ISO 12189-1: Additional compliance for mechanical testing of spinal implant components under physiological loading.
Product Advantages
Universal Testing Compatibility: Modular design accommodates screws (3.5–7.5 mm), plates (20–100 mm length), and rods (4.5–6.5 mm diameter).
Multi-Axis Loading: Simultaneous axial/torsional/shear loading replicates complex in vivo stresses.
High-Frequency Stability: 0.1–15 Hz dynamic control with ±0.05% force accuracy.
Biorelevant Environment: Temperature-controlled (37±1°C) lubrication bath with protein skimmer.
AI-Powered Analytics: Machine learning algorithms predict failure modes from initial test cycles.
Regulatory Compliance: Pre-loaded protocols for FDA/CE submission requirements.
Product Features
Electromagnetic Servo Actuators: 50 kN axial/25 Nm torsional capacity with programmable load ratios (R=0.1–10).
6-DOF Kinematic System: Replicates flexion/extension, lateral bending, and axial rotation (±20° range).
Dynamic Load Control: 0.1–15 Hz frequency range with programmable waveforms (sine, square, random).
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.
