Abstract:

BACKGROUND: Artificial hip joint simulator is used to evaluate wearing features and verify accordance between calculation results and actual results. However, testing results of wearing is greatly influenced by testing instrument.
OBJECTIVE: To design temperature control and lubrication components of novel artificial hip joint simulator to match the actual wearing mechanism and pattern and to better determine biological wearing parameters of artificial joint materials.
METHODS: Through the copper wire heating and proportion-integral-differential control, the temperature control was adjusted, and the drip lubrication was used to lubricate the wearing joints.
RESULTS AND CONCLUSION: The experimental observation showed that temperature control and lubrication parts design allows better simulation of human body environment by artificial hip joint simulator, so as to provide a more accurate and reliable in vitro test data for clinical application.
