Hip-knee joint integrated structure for powered prosthesis

ActiveCN116636963BImprove sports coordination abilitygood synergyArtificial legsHip flexionLimb amputation
The application discloses a hip-knee joint integrated structure for a power prosthesis, characterized in that the hip-knee joint integrated structure comprises a prosthesis hip joint (1), a power transmission system (2) and a prosthesis knee joint (3); the prosthesis hip joint (1) is fixedly connected with the prosthesis knee joint (3), and the power transmission system (2) is fixedly connected with the prosthesis hip joint (1); the power transmission system (2) simultaneously transmits power to the prosthesis hip joint (1) and the prosthesis knee joint (3) in two directions, drives the prosthesis hip joint (1) to complete a hip flexion action, and drives the prosthesis knee joint (3) to complete a knee flexion action. The hip-knee joint integrated structure can improve the joint motion coordination ability and improve the gait of an amputee, and a set of power system can be used to improve the energy utilization rate. The hip-knee joint integrated structure can also simulate the pulling effect of leg joint muscles on the joint, and meanwhile, the jerk feeling that may exist in the periodic motion process of rigid transmission is avoided.
