1one

Изобретение относитс  к медицине, а именно, к протезированию и протезостроению , и предназначено дл  протезировани  нижних конечностей.The invention relates to medicine, namely, to prosthetics and prosthesis, and is intended for prosthetics of the lower extremities.

Известна искусственна  стопа, содержаща  оболочку с наполнителем/ щиколотку и рессору fl.An artificial foot is known that contains a shell with a filler / ankle and a spring fl.

Применение известной стопы позвол ет осуществл ть опору на п тку и перекат, в некоторой степени приближа  ходьбу к норме, однако, не обеспечивает удовлетворительного отталкивани  носковой част1зю. Инвалид, пользу сь известной стопой, при каждом шаге проваливаетс  в момент отталкивани  носком из-за несоответстви  конструкции и свойств рессоры (опорного элемента) строению естественной стопы, что вызывает увеличение энергозатрат инвалида.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.

Целью изобретени   вл етс  уменьше ние энергозатрат инвалида при ходьбе путем создани  динамических характеристик стопы, адекватных естественной стопе человека..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.

Поставленна  цель достигаетс  тем, что рессора выполнена в виде двух ветвей, -одна из которых повтор ет кривизну естественного свода, а свободный конец другой соприкасаетс 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

с первой в области плюсне-фалангового сочленени . Причем, соотношение величины кривизны ветви в плоскости Шопаровского сустава к ве.личине кривизны другой ветви составл ет 1:1,5.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.

На фиг.,1 Изображена искусственна  стопа, разрез; на фиг. 2-4 - графики , иллюстрирую1Дие изменение динамическиххарактеристик ходьбы.Fig. 1 shows an artificial foot section; in fig. 2-4 are graphs illustrating the change in the dynamic characteristics of walking.

Регистраци  изменени  сил реакций опоры, проведенна  при помощи динамографической платформы, показала увеличение величины заднего толчка, свидетельствующее об уменьшении энергозатрат инвалида. Таким обратном, происходит увеличение как горизонтальной составл ющей, так и вертикальной составл ющей вектора опорной реакции в среднем на 8-10%, что вызывает при- ращёнйё главного вектора опорных реакций на 10%.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%.
