Abstract

Изобретение относитс  к медицинской технике, а именно к травматологии и ортопедии, и предназначено дл  создани  одномоментной симметричной дистракции или компрессии фрагментов кости. Устройство содержит кольцевые опоры 1-4, св занные дистракторами 5 в виде резьбовых стержней, на которых жестко закреплены зубчатые колеса 6, св занные зубчатым венцом 7. Узел управлени  8 расположен на одном из дистракторов. При вращении узла управлени  8 вращательное движение передаетс  через колеса 6 и зубчатый венец 7 на дистракторы 5, которые мен ют положение кольцевых опор 1-4. 1 ил.The invention relates to medical technology, namely to traumatology and orthopedics, and is intended to create simultaneous symmetric distraction or compression of bone fragments. The device comprises annular supports 1-4, connected by distractors 5 in the form of threaded rods, on which gears 6 are rigidly fixed, connected by a gear ring 7. Control unit 8 is located on one of the distracters. When the control unit 8 rotates, the rotational movement is transmitted through the wheels 6 and the ring gear 7 to distractors 5, which change the position of the annular supports 1-4. 1 il.

Изобретение относитс  к Медицинской технике, а именно к ортопедии и травматологии .The invention relates to medical technology, namely to orthopedics and traumatology.

Цель изобретени  -- упрощение конструкции .The purpose of the invention is to simplify the design.

На чертеже представлен аппарат, общий вид.The drawing shows the apparatus, a general view.

Аппарат содержит кольцевые опоры 1-4, св занные дистракторами 5 в виде резьбовы.х стержней, на которы.х жестко закреплены зубчатые колеса 6, св занные кинематической св зью, выполненной в виде зубчатого венца 7, установленного с возможностью вращени  между кольцевыми опорами. Узел 8 управ.тени  расположен на одном из дис- тракторов.The apparatus contains ring supports 1-4, connected by distractors 5 in the form of threaded rods, on which gears 6 are rigidly fixed, connected by a kinematic link, made in the form of a gear ring 7, mounted for rotation between the ring supports. Site 8 control shade is located on one of the tractors.

Аппарат работает следующим образом.The device works as follows.

При вращении узла 8 управлени  вращательное движение передаетс  через зубчатые колеса 6 и зубчатый венец 7 на все дистракторы 5, которые одновременно посредством резьбового соединени  измен ют положение кольцевых опор 1 -4.When the control unit 8 is rotated, the rotational movement is transmitted through the gears 6 and the gear ring 7 to all distractors 5, which simultaneously change the position of the annular supports 1-4 by means of a threaded connection.
