  • Publication number: 20230067978
    Abstract: A small-size multi-axis ankle joint prosthesis is provided. Two ends of each of four springs are fixedly connected with two spring seats at an upper part and at the lower part respectively. The joint axes are positioned in a space surrounded by the lower part, the four springs and the upper part. Front and rear perforated blocks in the joint axes are respectively in bolted connection with a fifth arc hole pair g and a sixth arc hole pair h of a second arc plate in the upper part. Left and right perforated blocks in the joint axes are respectively in bolted connection with a second arc hole pair e and a third arc hole pair f of the first arc plate in the lower part.

  • Publication number: 20220400814
    Abstract: A separated prosthetic foot with a transverse arch belongs to the technical field of manufacturing of artificial limbs. The characteristics of the transverse arch of the human foot are combined into the previous transverse-straight carbon fiber foot design to improve the stiffness of the prosthetic foot and reduce the weight of the prosthetic foot. A forefoot part employs a separated curved plate design, and two simple curved plates with different curvatures are used for simulating a complex curved surface of the transverse arch of the human, such that the manufacturing cost is reduced, and the various parts of the sole are non-uniform in stiffness distribution: the outer side of the foot is a single-layer forefoot plate with a smaller curvature and minor stiffness; and the inner side of the foot is a double-layer stacked forefoot plate, and the lower layer plate has a large radius in curvature and stiffness.
