[0002] At present, most of the ankle prostheses on the market have a single-axis structure, while the human ankle joint axis exists in the form of multiple axes. Therefore, the kinematic characteristics of the single-axis ankle prosthesis are quite different from those of healthy human limbs. Body discomfort during the process, unnatural walking gait, high energy consumption
The two-axis spatial angles of the existing multi-axis ankle prosthetic products on the market are fixed. For different amputee patients, the angles of the ankle joints of their healthy limbs are different, resulting in a low degree of personalized adaptation of such products. The adaptability of the road surface is low, and the movement coordination of the wearer's affected side and the normal side is poor

A multi-axis ankle joint prosthesis belongs to the technical field of bionic human prosthesis. The present invention is composed of an upper part, a lower part, a joint shaft part and a spring. It can be close to the structure of the ankle joint of the human body to the greatest extent, and has few parts, and the adjustment method is simple. It can be adjusted in units of 1°. shaking. The invention has a simple structure, is convenient for the wearer to self-adjust the joint axis angle suitable for himself, has a high degree of comfort for the wearer, and can improve the movement coordination of the limbs on the affected side and the normal side, can adapt to changes in different road surfaces, and reduces the energy consumption of the wearer .
Description
technical field [0001] The invention belongs to the technical field of bionic human prosthesis, in particular to a multi-axis ankle joint prosthesis. Background technique [0002] At present, most of the ankle prostheses on the market have a single-axis structure, while the human ankle joint axis exists in the form of multiple axes. Therefore, the kinematic characteristics of the single-axis ankle prosthesis are quite different from those of healthy human limbs. During the process, the body feels uncomfortable, the walking gait is unnatural, and the energy consumption is high. The two-axis spatial angles of the existing multi-axis ankle prosthetic products on the market are fixed. For different amputee patients, the angles of the ankle joints of their healthy limbs are different, resulting in a low degree of personalized adaptation of such products. The adaptability of the road surface is low, and the movement coordination of the wearer's affected and normal limbs is poor. ...
