Abstract

FIELD: medicine; particularly, prosthetics of hip joints. SUBSTANCE: acetabular component of endoprosthesis of hip joint has metal cup and polymer insert which is introduced into internal cavity of cup. Spherical part of metal cup has cuts extending from its top to its base and forming movable segments. Transverse recesses are made in points of cojugation of cup spherical part with the conical part of insert. Connections between transverse recesses fulfil the function of flexible support. External side of movable segments have rows of teeth with cutting edges. Upper faces of teeth are located over tangent line to the trajectory of their motion in turn relative to flexible support. External side of conical part of metal cup has multistart thread. EFFECT: higher efficiency.

Изобретение относится к медицине,а именно к протезированию тазобедренного сустава ортопедических больных. Предлагаемый компонент содержит металлическую чашку и полимерный вкладыш, который вводится во внутреннюю полость чашки. В изобретении на сферической части металлической чашки выполнены разрезы, проложенные от ее вершины до основания, образующие подвижные сегменты, а в месте сопряжения сферической части чашки с конической частью вкладыша прорезаны поперечные пазы, перемычки между которыми выполняют функцию гибкой опоры. На внешней стороне подвижных сегментов расположены ряды зубцов с режущими кромками. Верхние грани зубцов расположены по касательной к траектории их перемещения при повороте относительно гибкой опоры. Внешняя сторона конусной части металлической чашки снабжена многозаходной резьбой.The invention relates to medicine, namely to prosthetics of the hip joint of orthopedic patients. The proposed component contains a metal cup and a polymer liner, which is introduced into the inner cavity of the cup. In the invention, cuts are made on the spherical part of the metal cup, laid from its top to the base, forming movable segments, and in the place where the spherical part of the cup and the conical part of the insert meet, transverse grooves are cut, the bridges between which serve as flexible supports. On the outside of the movable segments are rows of teeth with cutting edges. The upper faces of the teeth are located tangent to the path of their movement when turning relative to a flexible support. The outer side of the conical part of the metal cup is provided with multi-thread.
