Description
(54) УСТРОЙСТВО ДЛЯ ФИКСАЦИИ ПОЗВОНКОВ(54) DEVICE FOR FIXING CALLS
II
Изобретение относитс к медицине и касаетс конструкции устройства дл фиксации позвонков.This invention relates to medicine and concerns the construction of a device for fixing vertebrae.
Известно устройство дл фиксации позвонков , содержащее пластину, состо щую из двух частей, соединенных с возможностью перемещени и фиксации одна относительно другой и имеющих на своих концах крючки дл наложени на остистые отростки. При фиксации переломов тел позвонков крючки известного устройства накладывают на их остистые отростки. После наложени крючков и совмещени отломков части пластины накладывают друг на друга внутренними поверхност ми и фиксируют стопорными винтами, чем обеспечиваетс необходимое нат жение между отломками 1.A device for fixing the vertebrae is known, comprising a plate consisting of two parts, connected with the possibility of moving and fixing one relative to the other and having hooks at their ends for imposing on the spinous processes. When fixing the fractures of the vertebral bodies, the hooks of the known device are placed on their spinous processes. After hooking and combining fragments, parts of the plate are superimposed on each other by internal surfaces and fixed with locking screws, which ensures the necessary tension between the fragments 1.
Однако в этом устройстве фиксаци позвонков не всегда достаточно устойчива.However, in this device, the fixation of the vertebrae is not always sufficiently stable.
Цель изобретени - повышение устойчивости фиксации позвонков.The purpose of the invention is to increase the stability of vertebral fixation.
Дл достижени поставленной цели устройство снабжено, по меньшей мере, одной промежуточной серьгой с фиксатором, при этом пластина имеет продольный паз под серьгу, а на концах частей пластины установлены винты, расположенные перпендикул рно ее вертикальной оси.To achieve this goal, the device is equipped with at least one intermediate earring with a retainer, while the plate has a longitudinal groove for the earring, and at the ends of the plate parts there are screws located perpendicular to its vertical axis.
На фиг. 1 изображено предлагаемое устройство , вид сбоку; на фиг. 2 - то же, вид спереди; на фиг. 3 - устройство в разобранном состо нии, вид сбоку.FIG. 1 shows the proposed device, side view; in fig. 2 - the same, front view; in fig. 3 - disassembled device, side view.
Устройство содержит пластину, состо щую из двух частей 1 и 2. Часть 2 пластины установлена на ее части 1 посредством хомутика 3 с возможностью перемещени . На концах частей пластины имеютс двухзубые крючки 4 и 5, служащие дл наложени на остистые отростки. Пластина имеет продольный паз 6, в котором с возможностью перемещени установлена промежуточна серьга 7 с фиксатором 8. На концах частей пластины установлены винты 9 и 10, расположенные перпендикул рно ее вертикальной оси.The device comprises a plate consisting of two parts 1 and 2. Part 2 of the plate is mounted on its part 1 by means of a clamp 3 with the possibility of movement. At the ends of the portions of the plate there are bicuspid hooks 4 and 5, which are used for imposing on the spinous processes. The plate has a longitudinal groove 6, in which an intermediate bar 7 with a latch 8 is mounted for movement. At the ends of the plate parts there are screws 9 and 10, which are located perpendicular to its vertical axis.
Устройство устанавливаетс следующим образом.The device is set as follows.
Обнажают одну из боковых поверхностей остистых отростков до дужек, на остистые отростки двух ближайших к очагу позвонков надевдют серьги 7, остистые отростки соседних позвонков охватывают двухзубыExpose one of the side surfaces of the spinous processes to the arches, on the spinous processes of the two vertebrae nearest to the center, they will wear earrings 7, the spinous processes of the adjacent vertebrae will cover the two teeth
