On the rod 1 with the stop thread 2 is installed by means of thread 4, the sleeve 3 with the external thread 5, the pitch of which is less than the pitch of the stop thread 2 of the rod 1, and the step of thread 4 is equal to the pitch of the external thread 5 of the sleeve 3, 1 Il.
Description
оabout
Изобретение относитс к медицине, в частности к травматологии и ортопедии, и предназначено дл лечени переломов костей .The invention relates to medicine, in particular to traumatology and orthopedics, and is intended for the treatment of bone fractures.
4 Цель изобретени - упрощение удалени винта из кости.4 The purpose of the invention is to simplify the removal of the screw from the bone.
На фиг.1 изображен компрессирующий винт, установленный в кость, общий вид,Figure 1 shows a compression screw installed in a bone, a general view,
Компрессирующий винт А.А.Сеидовой содержит стержень 1 с упорной резьбой 2 на одном конце и втулку 3, установленную на другом конце стержн 1 посредством резьбы 4, шаг которой совпадает с шагом наружной резьбы 5 втулки 3, причем шаг упорной резьбы 2 больше шага наружной резьбы 5 втулки 3. На торцах стержн 1 и втулки 3 выполнены соответственно шлицы 6 и 7.The compression screw A.A. Seidovoy contains a rod 1 with a stop thread 2 at one end and a sleeve 3 mounted on the other end of the rod 1 by means of thread 4, the pitch of which coincides with the pitch of the external thread 5 of the sleeve 3, and the step of the stop thread 2 is greater than the pitch of the outer the threads 5 of the sleeve 3. At the ends of the rod 1 and the sleeve 3 are respectively slots 6 and 7.
Компрессирующий винт используетс следующим образом.The compression screw is used as follows.
Соедин ют стержень 1 со втулкой 3. Вращением за шлицы 6 и 7 винт провод т через линию перелома кости. Так как стержень 1 и втулка 3 имеют различный шаг резьб, то при вращении винта обеспечиваетс компресси отломков кости. После образовани костной мозоли втулка 2The rod 1 is connected to the sleeve 3. The rotation for the splines 6 and 7 leads the screw through the bone fracture line. Since the rod 1 and the sleeve 3 have different thread pitch, when the screw is rotated, the bone fragments are compressed. After the formation of callus sleeve 2
выводитс из кости вращением за шлиц 7, затем вращением за шлиц 6 из кости выводитс стержень 1.pin 1 is pulled out of the bone by rotation for slot 7, then rod 1 is pulled out of the bone by spin for slot 6.
Винт обеспечивает упрощение удалени из кости после образовани костнойThe screw provides easier removal of the bone after bone formation.
мозоли, что позвол ет снизить травмирование костной ткани.corns, which reduces bone trauma.
