The Intramedullary Nails Internal-fixation Pull-out Force Tester is a specialized device designed to measure the axial pull-out strength of intramedullary nails and internal fixation screws. It evaluates the mechanical anchoring performance of implants in simulated bone or test materials, ensuring their stability and reliability under clinical loading conditions. This tester is widely used in orthopedic research, implant development, and quality control to verify that internal fixation devices can resist dislodgement and provide safe, long-term fixation in patients.
Standard
(1)ASTM F543: Standard specification for metallic medical bone screws (dynamic loading protocols).
(2)ISO 12172: Implants for surgery—Partial and total hip joint prostheses (fatigue testing methodologies).
(3)YY/T 0342: Chinese standard for surgical implant testing (cutout resistance evaluation).
Adaptive Compliance: Customizable protocols for emerging regulatory frameworks.
Product Advantages
(1)Dynamic Load Simulation: Replicates physiological gait-cycle forces (0–1.500 N at 5 Hz) for real-world failure prediction.
(2)Dual-Axis Measurement: Simultaneous tracking of cutout force (N) and angular displacement (°) during cyclic testing.
(3)Failure Prediction Algorithm: Proprietary software identifies pre-failure indicators using machine learning.
(4)High-Speed Imaging Integration: Syncs with external cameras for real-time deformation visualization (optional upgrade).
(5)Ergonomic Workflow: Touchscreen interface with pre-loaded ASTM/ISO templates and customizable test sequences.
(6)Modular Design: Quick-swap fixtures for testing various nail designs (helical blades, lag screws, etc.).
Product Features
(1)Electrodynamic Actuator: Delivers sinusoidal, triangular, or custom waveforms up to 10 Hz.
(2)6-DoF Load Cell: Measures axial/torsional forces and moments with 0.1% FS accuracy.
(3)High-Resolution Motion System: ±5° angular resolution for tracking nail migration paths.
(4)Thermal Stability Chamber: Controls test environment (-20°C to +50°C) for material property analysis.
(5)AI-Powered Analytics: Auto-generates failure mode maps comparing historical/current implant designs.
(6)Remote Access: Cloud-connected system for real-time collaboration and audit trails.
