Description
Изобретение относитс к медицинской технике, а именно к травматологии и ортопедии , и может быть использовано в качестве устройства дл фиксации и нат жени спиц в компрессионно-дистракционных аппаратах при внеочаговом остеосинтезе.
Цель изобретени - уменьшение трав- матичнссти при многократном нат жении спицы.
На чертеже изображено устройство, разрез.
Устройство содержит основной 1 и дополнительный 2 фиксаторы, выполненные идентично и устанавливаемые на спице последовательно .
В конусном отверстии корпуса фиксаторов 1, 2 размещены коническа разрезна цанга 3 и контактирующий с ней механизм зажима спицы в виде пружины 4 и резьбовой втулки 5.
Устройство используетс следующим образом.
Фиксаторы 1 и 2 надевают на перемещаемую спицу 6 Фиксатор 1 устанавливаетс неподвижно на кольце компрессионно-дистракционного аппарата. Степень зажати спицы б регулируют вращением резьбовой втулки 5, поджимающей пружиной 4 цангу 3. Фиксатором 2 совершают возвратно-поступательные движени , При его рабочем хода вправо спица 6 з жи- маетс цангой 3 и перемещаетс вместе с фиксатором 2. При его ходе влево спица 6 зажата цангой 3 фиксатора 1, а фиксатор 2 скользит вдоль спицы 6. Пружина 4 способствует зажатию спицы 6.
Устройство при многократном нат жении спицы в процессе лечени не требует перестановки фиксатора спицы на кольце компрессионно-дистракционного аппарата и таким образом предотвращает травмирование больного при демонтаже аппарата.
