摘要：
The invention relates to medicine, namely to traumatology and orthopedics and neurosurgery, and can be used in the surgical treatment of injuries and diseases of the spine using metal plates, or combinations thereof with bone grafting rear access. The technical result of the utility model is to provide a tight fit between the rectangular gear formed with a through channel in the form of an equilateral hexagon, with the bolt head, as well as increasing the compression effect in the fixing plates to the spinous processes. This is achieved in that the device comprises a flat rectangular housing, the proximal end of which is bevelled at an angle of 45 °. The apparatus also comprises a U-shaped frame, wherein the shaft is mounted with a sliding lever handle rotation type. The shaft is fixedly mounted bevel gear, sheltered housing and consisting of a conical gear wheel, mating with same impeller disposed in the chassis. Bevel gear mating with same impeller disposed housing device has a common rotating shaft with a rectangular toothed wheel, mating with the wheel system, hidden in the body of the device mounted in the distal portion of the U-shaped frame on an outer surface of one of its sides, which while the inner wall of the housing. The utility model as compared with the prior art, increases the reliability of the fixing device on the bolt head, and the fixation of the spine, reduces the time of the operation, reduces the risk of trauma to surrounding tissues and increases comfort when using the device.Полезная модель относится к медицине, а именно к травматологии и ортопедии, а также нейрохирургии и может быть использовано при оперативном лечении повреждений и заболеваний позвоночника с применением металлических пластин или их комбинаций с костной пластикой доступом сзади. Техническим результатом полезной модели является создание более плотной фиксации между прямоугольным зубчатым колесом, выполненным со сквозным каналом в форме равностороннего шестигранника, с головк
