Spinal Internal Fixation Components Tester

Standard

YY/T 0961-2014 (China): Specifies static/fatigue testing protocols for spinal fixation systems, including connection integrity and anti-loosening performance.

ASTM F1798-17 (International): Defines methodologies for evaluating the mechanical performance of spinal implant interconnections under cyclic loading.

ISO 12189-1: Additional compliance for connection durability testing in spinal implant assemblies.

Product Advantages

Universal Interconnection Testing: Modular fixturing accommodates screw-rod, plate-screw, and hook-rod connections.

Multi-Axis Load Application: Simultaneous axial/torsional/shear loading replicates complex physiological stresses.

Anti-Loosening Detection: High-precision torque sensors monitor connection degradation in real-time.

Biorelevant Environment: Temperature-controlled (37±1°C) lubrication bath with protein skimmer.

AI-Powered Analytics: Machine learning algorithms predict connection failure thresholds.

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 micro-movement analysis.

Safety Suite: Emergency stop, overload clutches, and laser-based specimen breakage detection.
