The invention discloses a multi-axis
ankle joint artificial limb and belongs to the technical field of bionic
human body prostheses. The multi-axis
ankle joint artificial limb comprises an upper part, a lower part, a joint shaft part and a spring, and the space angle of a joint shaft can be adjusted by adjusting the positions of all mechanisms, so that the
prosthesis can be attached to a
human body ankle joint structure to the greatest extent, and the
prosthesis has the advantages of few parts, simple adjustment mode and low cost. Adjustment can be carried out by taking 1 degree as a unit, the adjusting effect is high in reliability, the space size is small, the matching degree with people is high, the structure is stable, and shaking is not likely to happen. The structure is simple, a wearer can conveniently adjust the
joint axis angle suitable for himself / herself, the comfort degree of the wearer is high, the movement coordination of the limb on the affected side and the limb on the
normal side can be improved, different
road surface changes can be adapted, and the
energy consumption of the wearer is reduced.
