Description
Изобретение относитс к медицине, а именно к устройствам дл лечени заболеваний позвоночника.The invention relates to medicine, namely to devices for the treatment of diseases of the spine.
Известно устройство дл коррекции позвоночника - дистрактор Казьмина, содер- жащий верхнюю и нижнюю вилки с резьбой , резьбовый цилиндр и контргайки I.A spine correction device is known — a Kazmina distractor containing a threaded upper and lower forks, a threaded cylinder and lock nuts I.
Одним из недостатков данного устройства вл етс больша нагрузка на опорный позвонок, привод ща к резорбции ткани позвонка.One of the drawbacks of this device is the large load on the supporting vertebra, resulting in resorption of vertebral tissue.
Известно также устройство дл коррекции позвоночника - дистрактор Харринг- тона, содержащий стержень с резьбой, установленные на стержне крюки и гайки 2It is also known a spinal correction device — the Harrington distractor, containing a threaded rod, hooks and nuts 2 mounted on the rod.
Применение известного устройства не позвол ет добитьс максимальной коррекции деформации позвоночника одномоментно из- за опасности возможных переломов опорных элементов позвонков как непосредственно во врем операции, так и в послеоперационном периоде в результате перегрузки или резорбции дужек. Особо опасным или даже невозможным вл етс применение устройства у детей 8-12-летнего возраста, когда дужки позвонков не завершили костное сли ние с телами.The use of the known device does not allow one to achieve maximum correction of spinal deformity at one time because of the danger of possible fractures of the supporting elements of the vertebrae, both directly during the operation and in the postoperative period as a result of overload or resorption of the arches. Particularly dangerous or even impossible is the use of the device in children 8-12 years of age, when the vertebrae did not complete bone marrow with the bodies.
Целью изобретени вл етс получение максимальной коррекции позвоночника у детей путем распределени дистракционной нагрузки на позвонки.The aim of the invention is to obtain a maximum correction of the spine in children by distributing the distraction load on the vertebrae.
Поставленна цель достигаетс тем, что в устройстве дл коррекции позвоночника, содержащем стержень с резьбой, установленные с двух сторон на стержне крюки, гайки, крюки установлены на стержне с каждой стороны с помощью кронштейнов и гибких пластин с возможностью продольного перемещени , причем концы крюков имеют изгиб под углом 5-15°.The goal is achieved by the fact that in the spine correction device containing a threaded rod, hooks, nuts and hooks mounted on both sides of the rod are mounted on the rod on each side with the help of brackets and flexible plates with the possibility of longitudinal movement, with the ends of the hooks bending at an angle of 5-15 °.
На фиг.1 изображено устройство дл коррекции позвоночника, в двух проекци х; на фиг.2 - то же, со спаренным кронштейном с крюками.Fig. 1 shows a device for the correction of the spinal column, in two projections; figure 2 - the same, with a paired bracket with hooks.
Устройство дл коррекции позвоночника состоит из стержн 1 с резьбой 2, гайки 3 и контргайки 4 на одном конце и выступа 5 на другом. Оно снабжено элементами креплени 6 и 7, содержащими крюки 8-10 с разворотом в сторону под углом 5-15° укрепленными подвижно на кронштейне И. Крюки 9 и 10 расположены на гибкой пластинке 12 со спиральными прорез ми 13 на ее свободном конце.The spinal correction device consists of a rod 1 with a thread 2, a nut 3 and a lock nut 4 at one end and a protrusion 5 at the other. It is equipped with fastening elements 6 and 7, containing hooks 8-10 with a turn to the side at an angle of 5-15 ° fixedly mounted on bracket I. The hooks 9 and 10 are located on a flexible plate 12 with spiral slots 13 on its free end.
В кронштейне И расположено черв чное колесо 14, вступающее во взаимодействиеIn the bracket I there is a worm wheel 14, which interacts
со спиральными прорез ми 13 на гибкой пластинке 12. Кроме того, в кронщтейне 11 предусмотрено отверстие 15 дл соединительного стержн 16.with spiral slots 13 on the flexible plate 12. In addition, a hole 15 is provided in the brace 11 for the connecting rod 16.
Крюк 8 соединен подвижно с кронштейном 11, а крюки 9 и 10 - с пластинкой 12 и могут вращатьс вокруг оси 17, а перемещение вверх и вниз крюков 9 и 10 осуществл етс с помощью реечно-черв чно- го сочленени , а к переду и к заду - за счет гибкости пластинки 12.The hook 8 is movably connected to the bracket 11, and the hooks 9 and 10 are connected to the plate 12 and can be rotated around the axis 17, and the up and down hooks 9 and 10 are moved up and down by means of a rack and a worm with an articulated joint. bottom - due to the flexibility of the plate 12.
Кроме того, дл предупреждени самосто тельного раскручивани черв чного колеса 14 и ослаблени крюков 9 и 10, расположенных на пластинке 12, витки выполнены в виде пр моугольных треугольников и в соотношении 1:5.In addition, to prevent the self-driving of the worm gear 14 and loosening the hooks 9 and 10 located on the plate 12, the turns are made in the form of right triangles and in a 1: 5 ratio.
Устройство работает следующим образом.The device works as follows.
По общеприн тому методу осуществл ют доступ к задним элементам позвоночника. После выделени суставных отростков и дужек смежных двух позвонков с вогнутой стороны позвоночника при сколиозе к последним подвод т крюки в-10 элементов креплени 6 и 7. Подгонка крюков к опорным элементам позвонков производитс с помощью реечно-черв чного соединени . Элементы креплени 6 и 7, установленные под суставные отростки в дужки, фиксируют на стержне 1 и, подкручива гайку 3, производ т коррекцию деформации позвоночника .According to the generally accepted method, the posterior elements of the spine are accessed. After the separation of the articular processes and the arches of the adjacent two vertebrae on the concave side of the spinal column in case of scoliosis, the last hooks are delivered in –10 fastening elements 6 and 7. The hooks are fitted to the vertebral support elements by means of a worm joint. The fastening elements 6 and 7, installed under the articular processes in the arms, are fixed on the rod 1 and, tightening the nut 3, correct the deformity of the spine.
При сколиотических деформаци х позвоночника в краниальном отделе примен ютс крюки с разворотом в сторону деформации до 15°, а их изгиб, ширина и высота соответствуют контурам суставных отростков и дужки позвонка.For scoliotic spinal deformities in the cranial section, hooks are used with a turn in the direction of deformation up to 15 °, and their curvature, width and height correspond to the contours of the articular processes and the vertebral arch.
В процессе дистракции крюки 8-10 благодар их подвижности дополнительно самоустанавливаютс с оптимальной адаптацией к опорным элементам позвонка. После окончани коррекции рану послойно ушивают и накладывают гипсовый корсет.During the distraction process, the hooks 8-10, due to their mobility, are additionally self-aligning with optimal adaptation to the supporting elements of the vertebra. After completing the correction, the wound is sutured in layers and a plaster corset is applied.
В случа х необходимости, установленный элемент креплени 6 или 7 можно спарить с подобным и установленным таким же образом с другой стороны позвонков (фиг.2). Дл этого предусмотрены соединительный стержень 16 и в кронштейне 11 отверстие 15.In cases of necessity, the mounted fastening element 6 or 7 can be paired with a similar one and installed in the same way on the other side of the vertebrae (Fig. 2). For this, a connecting rod 16 and an opening 15 in the bracket 11 are provided.
Таким образом, предлагае.мое устройство позвол ет достигнуть максимальной коррекции деформации позвоночника, оно имеет п:ирокий диапазон применени (сколиоз, посттравматическа деформаци позвоночника , спонтилолистез) и позвол ет избежать встречающихс осложнений.Thus, the proposed device allows to achieve maximum correction of spinal deformity, it has the n: wide range of application (scoliosis, post-traumatic deformity of the spine, spontylolisthesis) and avoids the occurring complications.
