Hip simulator

This apparatus simulates the movements and mechanical loads induced by gait on the hip articulation. It allows testing the resistance to wear of bearing components of the hip prostheses (heap and cup).

Technical characteristics:

4 stations

Frequency: up to 1Hz

Load: programmable, up to 5 kN per station

Test medium: water or diluted bovine serum

Decoaptation is possible on 1 station

Example of load cycle (left: Paul's cycle) and movements (droite) allowed by Mateis Hip Simulator
