Abstract

Изобретение относитс  к медицинской технике, а более конкретно к эндопротезам суставов нижних конечностей, и предназначено дл  замены паталогически поврежденного естественного тазобедренного сустава. Цель изобретени  - повышение надежности фиксации эндопротеза путем заклинивани  костной ткани смежными участками. Эндопротез содержит корпус 1 в виде конической втулки, со стороны большего диаметра которой имеетс  примыкающий к ней цилиндрический по с 2. Расположенные на его поверхности лопасти выполнены в виде нескольких витков ребристого выступа 3, опо сывающего корпус подобно нитке резьбы, при этом толщина ребристого выступа на цилиндрическом участке корпуса увеличена, вследствие чего рассто ние между стенками смежных витков ребристого выступа соответственно уменьшено, а помещенный в корпусе вкладыш 9 на входе в свою сферическую полость выполнен в форме расширенного наружу конуса. 3 ил.The invention relates to medical technology, and more specifically to endoprosthesis joints of the lower extremities, and is intended to replace a pathologically damaged natural hip joint. The purpose of the invention is to increase the reliability of fixation of the endoprosthesis by jamming the bone tissue in adjacent areas. The endoprosthesis comprises a housing 1 in the form of a conical sleeve, on the larger diameter side of which there is a cylindrical adjoining it with 2. The blades located on its surface are made in the form of several turns of the ribbed protrusion 3, which surrounds the body like a thread, and the ribbed protrusion is the cylindrical section of the housing is increased, as a result of which the distance between the walls of adjacent turns of the ribbed protrusion is reduced accordingly, and the insert 9 placed in the housing at the entrance to its spherical cavity n in the form of expanded outwardly conical. 3 il.
