Abstract

FIELD: medicine, particularly, prosthesis. SUBSTANCE: prosthetic device has joint with slider made in form of hollow cylindrical cartridge having rod and adjusting screw; moreover cartridge is divided by movable piston on two compartments, one of which is damper filled with balls; spring-loaded element and bush are installed in tandem on link, having stop in its lower part; movable element with latch is attached to supporting platform and front section of knee joint; for eliminating knock junction between slider, supporting platform and front section of knee joint is executed in form of sleeve with conical hollow bolt having internal thread ensuring possibility of axial displacement. EFFECT: increased lifetime of knee joint due to reducing redundant junctions and adjusting friction in hip prosthesis during walking at different rate of speed. 2 cl, 3 dwg

Изобретение относится к медицине, а именно к протезированию и протезостроению. Цель изобретения - повышение ресурса работы коленного шарнира путем уменьшения избыточных связей, регулировки трения при ходьбе на протезе бедра в разном темпе, ползун шарнира выполнен в виде полой цилиндрической обоймы со штоком и регулировочным винтом, разделенной подвижным поршнем на две полости, из которых одна выполнена в виде демпфера, заполненного шариками, а на кулисе последовательно установлены упругий элемент и втулка, на нижней части кулисы содержится упор, причем на опорной площадке и переднем звене коленного шарнира установлен подвижный элемент с фиксатором, причем для устранения стука соединения ползуна и опорной площадки, с передним звеном коленного шарнира выполнены в виде конической втулки с коническим пустотелым болтом, внутри которого содержится резьба, обеспечивающая осевое перемещение.The invention relates to medicine, namely to prosthetics and prosthetics. The purpose of the invention is to increase the service life of the knee hinge by reducing excess connections, adjusting friction when walking on the hip prosthesis at a different pace, the hinge slider is made in the form of a hollow cylindrical cage with a rod and an adjusting screw, divided by a moving piston into two cavities, one of which is made in in the form of a damper filled with balls, and an elastic element and a sleeve are sequentially mounted on the wings, on the lower part of the wings there is an abutment, and on the supporting platform and the front link of the knee hinge flax movable member with a clamp, and to eliminate knock compounds of the slider and the support platform, with the front link of the knee joint are designed as conical sleeves with tapered hollow bolt within which the thread is contained, providing the axial movement.
