Description

tt

Изобретение относитс  к медицине, а именно - к протезированию,The invention relates to medicine, namely to prosthetics,

Известен протез голени на усеченную конечность, включающий стопу и эластичную оболочку, в которую заключены щиколотка с подвижно сочлененным каркасом стопы Щ.Known prosthetic leg on the truncated limb, which includes the foot and the elastic sheath, which encloses the ankle with a movable articulated frame of the foot O.

Недостатками известного протеза .  вл ютс  недостаточна  его устойчивость , частые с5лучаи травмировани  кожных покровов усеченной конечности а также случаи деформации кости усеченной конечности при протезировании )ижних конечностей у детей.The disadvantages of the famous prosthesis. its inadequate stability, frequent cases of injury to the skin of the truncated limb, and cases of deformity of the truncated limb during prosthetic repair of the extremities in children.

Цель изобретени  - повышение устойчивости при ходьбе и уменьшение травмировани  усеченной конечности.The purpose of the invention is to increase the stability when walking and to reduce the injury to the truncated limb.

Поставле нна  цель достигаетс  применением голеностопного сочленени  кулачкового типа, образованного ;щиколоткой и плоскостью каркаса, а именно - дистальна  часть щиколотк« имеет утолщение в виде кулачка и, изогнутый хвостовик, а проксимальна  часть щиколотки снабжена резьбой; каркас стопы выполнен криволинейным, с загибом у п тки и содержит винтовой упор.The goal is achieved by using an ankle joint of the cam type, formed by the ankle and the carcass plane, namely, the distal part of the ankle has a thickening in the form of a cam and, a curved shank, and the proximal part of the ankle is threaded; the skeleton of the foot is made curvilinear, with a bend in the heel and contains a screw stop.

На чертеже показан общий вид искусственной стопы в разрезе.The drawing shows a General view of the artificial foot in the section.

Искусственна  стопа состоит из эластичной оболочки 1,в которой расположены жест кий каркас 2, имеющий загиб 3 у п тки и винтовой упор 4, а также щиколотки 5, у которой дистальна  часть имеет утолщение и изогнутый хвостовик, кулачок 6 с резиновым покрытием 7, а проксимальна  часть щиколотки снабжена резьбовым o окончанием.The artificial foot consists of an elastic shell 1 in which a rigid frame 2 is located, having a bend 3 at the heel and a screw stop 4, as well as an ankle 5, in which the distal part has a thickening and a curved shank, a cam 6 with a rubber coating 7, and the proximal part of the ankle is provided with a threaded o end.

Устройство протеза работает следующим образом.The device of the prosthesis works as follows.

Винтовым упором 4 производитс  индивидуальна  регулировка сгибани  стопы.The deformation of the elastic sheath 1 and the stop of the cam 6 into the adjustable screw stop 4 at the exact bend 3. The screw stop 4 individually adjusts the flexion of the foot.
