Abstract
Изобретение относитс к медицине, а именно к травматологии и ортопедии, и предназначено дл лечени переломов шейки бедренной кости. Устройство содержит корпус и установленные в нем винт 1, на одном конце которого расположена тарельчата пружина 2, и узел захвата в виде наконечника 3 раздвижени с резьбовым хвостовиком 4 и установленной на нем упругой втулки 5. Винт 1 выполнен с наружной муфтой 11, соединенной с винтом 1 и хвостовиком 4 по резьбе и скреплен с цилиндром 6. Корпус выполнен в виде раздвижных св занных шлицевым соединением цилиндров 6 и 7, причем цилиндр 7 выполнен с накостным фланцем 8, а цилиндр 6 св зан с наконечником 3 деротационным элементом. Перемеща наконечник 3, раздвигают втулку 5 - обеспечиваетс надежный захват проксимального фрагмента, а враща винт 1, сжимают пружину 2 - обеспечиваетс высока динамическа компресси фрагментов костей.2 ил.The invention relates to medicine, namely to traumatology and orthopedics, and is intended for the treatment of femoral neck fractures. The device includes a housing and a screw 1 installed therein, at one end of which a spring 2 is located, and a gripping device in the form of a tip 3 extending with a threaded shank 4 and an elastic sleeve 5 mounted on it. The screw 1 is made with an external coupling 11 connected to the screw 1 and shank 4 along the thread and fastened to the cylinder 6. The body is made in the form of sliding connected cylindrical joints of cylinders 6 and 7, the cylinder 7 being made with an outboard flange 8, and the cylinder 6 is connected to the tip 3 with a de-rotating element. By moving the tip 3, the sleeve 5 is pushed apart - a secure grip of the proximal fragment is ensured, and by turning the screw 1, the spring 2 is compressed - a high dynamic compression of the bone fragments is achieved. 2 Il.
