Torsion Fatigue Tester for Spinal Pedicle Screw - Rod Systems

Specifically, this tester can be used for the following tests: - Evaluate the fatigue life of spinal pedicle screw - rod systems with different materials and designs under torsional stress. - Study the deformation and damage of spinal pedicle screw - rod systems under long - term loading. - Compare the differences in torsional fatigue performance among spinal pedicle screw - rod systems from different brands and models. - Provide scientific evidence for the research, development, production, and quality control of spinal implants.
