multiaxial mechanical simulator for wear tests on articular orthopedic prostheses

摘要

MULTIAXIAL MECHANICAL SIMULATOR FOR WEAR TESTS IN JOINT ORTHOPEDIC PROSTHESES. Consisting of bench (1) with part of the electronic control systems of motion systems and the main metal frame (2) with interchangeable parts and mechanical simulator that has four independent motion axes, driven by synchronous motors (3) where At its center is the lower mechanical assembly (6) and the upper lever for force application (7) and the opposite end of the auxiliary mechanical assembly (8) with displacement spindle are articulated at the top of the lateral projection. lever (7), where the mechanical subassembly (9) is allocated with a motor for internal / external rotational movements (10), and with said lower mechanical assembly (6) with a test chamber (11) with specific fluid with a temperature of 37 198 C sym 2 198 C, the development of which aims to achieve a multi-axis joint prosthesis wear testing machine, which faithfully reproduces parameters for normalized meters and biological signals describing kinematics, kinetics, and other systemic conditions inherent in joints such as the hip, knee, ankle, cervical or lumbar spine, intervertebral disc, shoulder, elbow, and wrist.
