| Model# | GF2580 |
|---|
The GF2580 fatigue fixture meets the requirements of ASTM F2580 to test the fatigue performance of modular, proximally fixed, femoral hip implants. The test specimen holder is sized to accommodate a variety of test specimen mounting angles and positions, while allowing variation of the holder's X-Y position on the machine base to ensure the force line of action runs through the center of the femoral head. Loads are applied to the implant head by a cylindrical loading head attached to a low-friction bearing to prevent off-axis loading. Since biomedical implants will be used in vivo, the hip implant fatigue fixture is designed for use with biobaths to test in saline environments.
A special alignment fixture is also available to ensure precise and accurate fixturing of the femoral hip implant in the specimen holder. This fixture allows precision measurement and adjustment of the implant mounting angle and height.The GF2580 hip implant fatigue fixture also meets the requirements of ASTM F1440 for testing the fatigue performance of metallic stemmed hip arthroplasty femoral components without torsion and ASTM F1612 for testing the fatigue performance of metallic stemmed hip arthroplasty femoral components with torsion.
