Robossis: Orthopedic Surgical Robot

Alignment of femur fractures requires high precision in the presence of a huge traction force which is very arduous. The difficulties are mainly due to the bone’s elongated anatomy and its strong counteracting muscles, which necessitate a high traction force to be exerted by the surgeon and the medical team. Robossis eliminates the need for the surgeon to apply this force, and significantly improves the precision of the procedure. This platform will balance the accuracy, payload, and workspace for the surgeon, resulting in more efficient, successful surgeries. The experimental tests on a phantom reveal that the mechanism is well capable of applying the desired reduction steps against the large muscular payloads with high accuracy.
