The Spinous Process Fixation Plate System Fatigue Testing Machine is a specialized device used to evaluate the fatigue performance of spinal fixation systems that use spinous process plates. It applies repeated mechanical loads, such as bending, compression, and torsion, to simulate physiological conditions and assess the durability, strength, and failure characteristics of the implant under long-term use.
Application
The spinous process fixation plate system is designed for lamina reconstruction following spinal canal decompression surgery. Based on the clinical use of spinous process fixation plates, a simplified mechanical model is proposed, establishing testing methods for the static compression-bending performance and compression fatigue performance of the plate system. These test methods provide guidance on loading types and methods, principles for measuring displacement, determining yield load, and evaluating stiffness and strength.
The M Electromagnetic series equipment offers precise sinusoidal load control with stable peak values. It provides professional testing fixtures and accurate, effective test protocols (SOP), supporting mechanical performance analysis of implants.
