Description

(54) ARTIFICIAL STOP

one

The invention relates to medicine, namely, to prosthetics and prosthesis, and is intended for prosthetics of the lower extremities.

An artificial foot is known that contains a shell with a filler / ankle and a spring fl.

The use of a known foot allows for the support of the heel and roll, to a certain extent approaching walking to normal, however, it does not provide a satisfactory repulsion of the nose portion. A disabled person using a well-known foot at each step fails at the moment of repulsion with a toe due to the incompatibility of the structure and properties of the spring (support element) with the structure of the natural foot, which causes an increase in the energy consumption of the disabled person.

The aim of the invention is to reduce the energy consumption of a disabled person when walking by creating dynamic foot characteristics that are adequate to a person’s natural foot.

The goal is achieved by the fact that the spring is made in the form of two branches, one of which repeats the curvature of the natural dome, and the free end of the other is in contact

with the first in the area of the metatarsophalangeal joint. Moreover, the ratio of the curvature of the branch in the plane of the Shoparovsky joint to the value of the curvature of the other branch is 1: 1.5.

Fig. 1 shows an artificial foot section; in fig. 2-4 are graphs illustrating the change in the dynamic characteristics of walking.

ten

The artificial foot contains a shell 1 with filler 2 in the form of rubber or polyurethane foam, a cyclone 3 and a spring 4 in the form of two branches 5, 6, One branch - branch 5 repeats the curvature of the natural vault, and the free end of branch 6 is in contact with branch 5 in ob.pasty metatarsophalangeal

articulation. The ratio of the curvature of the branch in the plane of the Shoparovsky joint to the curvature of the other branch

20 is 1: 1.5.

Artificial foot works as follows.

In a position where the load is applied to the entire surface of the foot, the spring 4 deforms and cancels the energy. With this free end

branch 6 slides along branch 5. at the moment

reliance on the toe, corresponding to the rear push, accumulated vy30

frees up and contributes to the creation of an elastic back thrust.

The registration of changes in the support reaction forces carried out using a dynamographic platform showed an increase in the magnitude of the back shock, indicating a decrease in the energy consumption of the disabled person. Thus, an increase in both the horizontal component and the vertical component of the support reaction vector increases by an average of 8-10%, which causes an increase in the main vector of support reactions by 10%.

Claims (2)

1. An artificial foot containing a casing with a filler, an ankle and a spring, o-T l and h aa C with the fact that, in order to reduce
energy consumption of a disabled person when walking by creating dynamic characteristics of feet that are adequate to the natural foot of a person, the spring is made in the form of two branches, one of which repeats the curvature of the natural arch, and the free end of the other is in contact with the first in the area of the phalsan-phalangeal joint.
2. Stop pop. 1, characterized in that the ratio of the curvature of the branch in the plane of the Shoparovsky joint to the curvature of the other branch is 1: 1.5.
