Lower Limb Prosthesis Cyclic Testing
At the Orthopaedic Trauma Institute at San Francisco General Hospital, I work on a wide range of novel orthopaedic technologies, with a focus on mechanical design, fabrication and testing. For each of these testing setups, I build them entirely from scratch using primarily the mill and other machine shop tools. Mechanical tests are performed on medical devices, sometimes in cadaveric specimens, in the MTS Bionix 858 (a servohydraulic testing system) along with an Optotrack Tracking System to track movement of test subjects in 3D space.
For this particular test, we are performing cyclic test on a novel 3D printed lower prosthesis. Running the leg through this test will ensure that it can be worn by a real human being and has the lifetime as tested in the machine. Following previous studies, both follow ISO Standard 10328 (Structural testing of lower limb prostheses).
