Изобретение относитс  к медицине, а именно к протезостроению и протезированию .The invention relates to medicine, namely to prosthetic engineering and prosthetics.

Известна стопа с голеностопным амортизатором , примен юща с  при минимальном укорочении конечности, состо ща  из сварного металлического каркаса, резиновых амортизаторов, эластичной облицовки и голеностопного узла.A foot with an ankle damper is known, which is used with minimal shortening of the limb, consisting of a welded metal frame, rubber shock absorbers, an elastic lining and an ankle unit.

Однако эта стопа из-за своей т жести и громоздкости не может быть использована у детей при минимальном укорочении нижней конечности. Кроме того, передний и задний амортизаторы стопы при ходьбе не дают ощущени  голеностопного шарнира, а перекат осуществл етс  за счет эластичности носковой части стопы. Технологический процесс изготовлени  этой стопы трудоемкий и сложный.However, this foot, due to its severity and bulkiness, cannot be used in children with minimal shortening of the lower limb. In addition, when walking, the front and rear shock absorbers of the foot do not give the feeling of an ankle joint, and the roll is carried out due to the elasticity of the forefoot. The technological process of making this foot is laborious and complex.

Известна искусственна  стопа дл  протеза бедра, состо ща  из металлического каркаса и шин в месте их соединени , образующих голеностопные шарниры, пружинных амортизаторов и эластичной носковой части.A known artificial foot for a hip prosthesis, consisting of a metal carcass and tires at the junction, forming ankle joints, spring shock absorbers and an elastic forefoot.

Однако известна  стопа предназначена дл  протеза бедра и, следовательно, не может быть использована при минимальном укорочении нижней конечности у маленьких детей. Голеностопные шарниры не имеют развилки шин, что  вл етс  необходимым использование общей оси дл  соединени  их, а это исключает использование известной стопы при минимальном укорочении нижней конечности на 1-2 см, ибо при более значительном удлинении конечности (5-7 см) приводит к нестабильности голеностопного сустава, высоко расположенного над площадью опоры.However, the known foot is intended for a hip prosthesis and, therefore, cannot be used with minimal shortening of the lower limb in young children. Ankle joints do not have a fork in the tires, which is necessary to use a common axis to connect them, and this eliminates the use of a known foot with a minimum shortening of the lower limb by 1-2 cm, because with a more significant lengthening of the limb (5-7 cm) leads to instability ankle joint, high above the support area.

Целью изобретени   вл етс  протезирование длинных культей у маленьких детей .The aim of the invention is prosthetics of long stumps in young children.

Поставленна  цель достигаетс  тем, что по гипсовому позитиву конечности изготавливают жесткую пластмассовую приемную гильзу, дистальный конец которой устанавливают между шинками искусственной стопы . Шинки к стопе фиксируют при помощи металлических заклепок.The goal is achieved by the fact that according to the plaster positive of the limbs, a rigid plastic receiving sleeve is made, the distal end of which is placed between the shank of an artificial foot. Sinks to the foot is fixed with metal rivets.

На фиг,1 изображена искусственна  стопа с шинками; на фиг.2 - искусственна  стопа, соединенна  с приемной гильзой, а также резиновыми амортизаторами и эластичной облицовкой; на фиг.З - разрез А-А на фиг.2; на фиг.4 - разрез Б-Б на фиг.2.Fig. 1 shows an artificial foot with shanks; Fig. 2 shows an artificial foot connected to a receiving sleeve, as well as rubber shock absorbers and an elastic lining; on fig.Z - section aa in figure 2; figure 4 - section bb in figure 2.

Искусственна  стопа содержит металлический каркас 1, кра  которого изогнуты и выполнены а виде ребер 2 жесткости, соедин ющийс  посредством ушек 3 и винтов 4 с шинками 5, образу  голеностопные шарниры 6. К переднему краю металлического каркаса фиксированы пружинные пластиныThe artificial foot contains a metal frame 1, the edges of which are bent and made in the form of stiffening ribs 2, connected by means of lugs 3 and screws 4 to taverns 5, forming ankle hinges 6. Spring plates are fixed to the front edge of the metal frame

7 в виде носка стопы. Искусственную стопу соедин ют с приемной гильзой конечности 8 шинками 5 при помощи заклепок 9. Между приемной гильзой и передним и задним концами металлического каркаса расположены резиновые амортизаторы 10. Искусственна  стопа и приемна  гильза облицована эластичным материалом 11. Это позвол ет осуществл ть протезирование детей даже при укорочении нижней конечности с эквинусным положением стопы до 1 см и выработать правильный стереотип ходьбы.7 in the form of a toe. An artificial foot is connected with the receiving sleeve of the extremity 8 by the skirts 5 by means of rivets 9. Rubber shock absorbers 10 are located between the receiving sleeve and the front and rear ends of the metal frame. The artificial foot and the receiving sleeve are lined with elastic material 11. This allows the prosthetics of children to be performed even shortening the lower limb with the equinus position of the foot to 1 cm and develop the correct walking pattern.

Искусственна  стопа работает следующим образом.Artificial foot works as follows.

При заднем толчке пружинные амортизаторы 7 носковой части искусственной стопы сгибаютс , в то врем , как при сн тии нагрузок носок искусственной стопы возвращаетс  в первоначальное положение. Передний толчок осуществл етс  за счетWith the rear push, the spring-loaded shock absorbers 7 of the forefoot of the artificial foot are bent, while, when the load is removed, the toe of the artificial foot returns to its original position. Front push is due to

движений в голеностопном шарнире 6 и упругости заднего резинового амортизатора 10. Перекат искусственной стопы в голеностопном шарнире осуществл етс  за счет переднего амортизатора 10 и эластичнойmovements in the ankle joint 6 and the elasticity of the rear rubber damper 10. The roll of the artificial foot in the ankle joint is carried out by the front shock absorber 10 and elastic
