Изобретение относитс к медицинской технике, а именно к травматологии , и предназначено дл лечени переломов костей.The invention relates to medical technology, namely to traumatology, and is intended for the treatment of bone fractures.
Известно устройство, содержащее резьбовой стержень и установленную на нем втулку с лепестками, имеющими винтовую нарезку l. .A device containing a threaded rod and a sleeve mounted thereon with petals having a screw cut l is known. .
Нарезка на лепестках втулки имеет профиль обычной метрической резьбы с притупленной кромкой при вершине и диаметром основани , меньшим диаметра гладкой цилиндрической поверхности цанговой втулки. Така форма нарезки на лепестках цанговой ьтулки фиксатора не обеспечивает при проведении остеосинтеза надежную фиксацию ее в канале костной ткани.The cutting on the petals of the sleeve has the profile of a conventional metric thread with a blunt edge at the top and a base diameter smaller than the diameter of the smooth cylindrical surface of the collet sleeve. Such a form of cutting on the lobes of the collet clamp bushing does not provide for reliable fixation in the bone tissue channel during osteosynthesis.
Целью изобретени вл етс обеспечение надежной фиксации костных от ломков.The aim of the invention is to ensure reliable fixation of bone from brittle.
Это достигаетс тем, что винтова нареэка «а лепестках втулки выполнена в виде упорной резьбы, профиль которой имеет форму пр моугольного тре угольника гипотенузой, г обращенной в сторону торцайтулки и режущей кромкой при вершине.This is achieved by the fact that the screw nareek and the petals of the sleeve are made in the form of a stop thread, the profile of which has the shape of a rectangular triangle by the hypotenuse, facing the end face and the cutting edge at the apex.
На чертеже изображен фиксатор Шестерни Н.А. с частичным ра-резом. The drawing shows the latch Gear N.A. with partial cut.
Он содержит цанговую втулку 1 с наружной винтовой нарезкой 2 на лепестках .3 и внутренней резьбой 4 на противоположном конце и стержень 5 с резьбой дл ввинчивани в отверстие цанговой втулки, на одном конце которой имеетс упорный корпус 6, а на другом- головка 7 со шлицом.It contains a collet sleeve 1 with an external screw thread 2 on the petals .3 and an internal thread 4 at the opposite end and a rod 5 with thread for screwing into the hole of the collet sleeve, at one end of which there is a stop body 6, and at the other end there is a head 7 with a slot .
Устройство работает следующим образом .The device works as follows.
По рентгеновскому снимку определ ю место и направление введени устройства . Сверлом, диаметр которого равен гладкой части предложенного устройств предварительно просверливают канал в костной ткани. Затем цанговую втулку ввинчивают в кость. Режуща крюмка резьбы на лепестках обеспечивает возможность без особых усилий ввести втулку в проделанный канал, при этом травматизаци тканей незначительна. Затем ввод т резьбовой стержень 5, который разводит лепестки устройства и надежно закрепл ет его в костной ткани.An x-ray determines the place and direction of insertion of the device. A drill whose diameter is equal to the smooth part of the proposed device is pre-drilled a channel in the bone tissue. Then the collet sleeve is screwed into the bone. Cutting the hook of the thread on the petals provides the opportunity to effortlessly insert the sleeve into the channel, while tissue trauma is negligible. Then a threaded rod 5 is inserted, which spreads the petals of the device and securely holds it in the bone tissue.
Упорна резьба на лепестках обеспечивает повышение прочности фиксации отломков и стабильность остеосинтеза несмотр на развивающийс остеопороэ кости вокруг устройства, исключаетThe resistant thread on the petals provides increased strength of the fixation of fragments and the stability of the osteosynthesis despite the developing osteoporosis of the bone around the device, eliminates
возможность аксиальной миграции устройства . Извлечение стержн осуществл ют в обратном пор дке, т.е. сначала удал ют фиксирующий стержань, а затемртулку .possibility of axial device migration. Removing the rod is carried out in reverse order, i.e. first, the fixing rod and then the sleeve are removed.
