Thigh low-squatting type prosthetic limb

Abstract

The invention provides a thigh squatting prosthesis. The prosthesis comprises a connecting seat of a receiving cavity, a knee joint part, a main tension spring part, a shank part consisting of a main stand bar and a lower stand bar, an ankle joint part and an assistant tension spring part, wherein the upper end of the shank part is connected with the knee joint part, while the lower end is connected with the ankle joint part; and the main tension spring part and the assistant tension spring part are arranged between the knee joint part and the ankle joint part. The knee joint part adopts a gear and rack mechanism, and the knee joint drives a main spring component and an assistant spring component in a squatting process, so the ankle joint part generates a corresponding prosthesis squatting function; a screw thread adjustment locking mechanism arranged between the main stand bar and the lower stand bar can adjust the height of the prosthesis, and a spherical joint in the ankle joint part is elastically connected with multiple points, so that buffering power can be reduced when a person walks, and comfortableness and flexibility of walking can be improved. The mechanical prosthesis has the advantages of simple structure, good upslope and downslope performance, light and flexible application, safety and reliability, low cost and convenient assembly and maintenance.

Description

Technical field: [0001] The invention relates to a prosthesis for disabled people with thighs. Background technique: [0002] Due to traffic accidents, industrial injuries, diseases or other accidents, the number of patients with incomplete thighs is increasing. The lack of legs not only makes people unable to walk normally, but also brings great inconvenience to people's life and work, and greatly harms the health of patients. Soul, and even make patients lose the courage to live. In order to make patients with disabled thighs able to stand on their own, people have designed a variety of thigh prostheses to help patients walk, such as load-bearing self-locking thigh limbs, link-type prostheses, etc., but existing The various types of thigh prostheses are complex in structure and expensive, and most patients are unable to use them. Moreover, the knee joints of ordinary thigh prostheses cannot squat down, and patients cannot squat down and sit up. Safe and reliable, easy to ...
