Embodiment Construction

[0016] The inventors of the present invention have found that the existing lower limb prosthesis, its ankle joint is generally rigid, and cannot simulate the moderate activity of the ankle joint when a normal person walks, so it is less comfortable to use; moreover, the existing lower limb prosthesis, its The height of the prosthesis corresponding to the vertical part of the calf is fixed. For users with different body sizes, it is necessary to customize lower limb prostheses of different heights; moreover, after a period of use of the prosthesis, the height of the prosthetic body will decrease. Phenomenon, thereby making the height of both feet inconsistent, affecting the normal walking function of the user.

[0017] In view of the above problems, the inventor of the present invention proposes a technical solution, which is specifically as follows: a calf prosthesis, characterized in that it includes the sole of the foot, a wheel bowl, a wheel sphere, a limiting unit, and a le...

Abstract

The invention discloses a below-knee artificial limb, which comprises a sole, a wheel bowl, a wheel ball body, a limiting unit and a leg rod, wherein the wheel bowl is fixedly arranged on the sole; the wheel ball is matched with the wheel bowl body; the wheel ball at the lower part of the wheel bowl body can rotate in the wheel bowl; the wheel ball body has a hollow structure and is provided with internal thread; the leg rod is provided with external thread matched with the internal thread of the wheel ball body; the connecting length of the leg rod and the wheel ball body is adjusted by rotating the leg rod; the limiting unit is positioned between the wheel bowl and the wheel ball body for limiting the rotation direction and amplitude of the wheel ball in the wheel bowl; and all the sole, the wheel bowl, the wheel ball body and the leg rod are made of a carbon fiber material. According to the below-knee artificial limb, the length of the entire below-knee artificial limb can be adjusted, and the rotation of an ankle joint of a human body can be simulated by the below-knee artificial limb, so that the problems of incapability of adjusting height, labor-consuming walking and poor safety existing in the conventional below-knee artificial limb are solved.

Description

technical field [0001] The invention relates to the field of artificial limb manufacturing, in particular to a calf artificial limb. Background technique [0002] For disabled people with amputations, the most common restoration measure at present is to install artificial limbs to obtain basic limb functions. In order to ensure the stability and strength of the existing lower limb prostheses, the ankle joints are generally rigidly fixed at a certain angle, that is, the ankle joints cannot be moved; at the same time, the height of the lower limb prostheses cannot be adjusted, and must be customized for each disabled person. design. Because the user itself has certain limb defects, the strength of the residual limb and the balance of the body etc. are all weak, so the use of this prosthesis is not good for the user in terms of comfort and convenience. Moreover, the manufacturing cost of this custom-made prosthesis is very high, and the financial burden on the user is very he...
