Abstract
Использование: в медицине дл остео- синтеза переломов предплечь . Сущность изобретени : устройство выполнено в виде стержн с п тигранной частью, пр моугольной средней частью и концом цилиндрической формы. П тое ребро п тигранной части противоположно основанию с прилежащими пр мыми углами. П тигранна часть дугообразно изогнута с вогнутостью по п тому ребру. Пр моугольна часть изогнута в плоскости, перпендикул рной плоскости изгиба п тигранной части. Три грани п тигранной части совпадают с гран ми пр моугольной части. Грани п того ребра плавным изгибом переход т в грань пр моугольной части. 2 ил.Usage: in medicine for osteosynthesis of forearm fractures. SUMMARY OF THE INVENTION: the device is made in the form of a rod with a polyhedral part, a rectangular middle part and a cylindrical end. The fifth rib on the tiger's part is opposite to the base with adjacent right angles. The ран tigranous part is curved arcuately with concavity along the ridge along the ridge. The rectangular part is curved in a plane perpendicular to the plane of bending and the tiger's part. The three faces of the n tigered part coincide with the faces of the rectangular part. The faces of the fifth rib smoothly bend into the face of the rectangular part. 2 ill.
Description
Изобретение относитс к медицине, а именно к травматологии и предназначаетс дл надежной интрамедулл рной фиксации фрагментов костей предплечь .The invention relates to medicine, namely to traumatology, and is intended for reliable intramedullary fixation of fragments of bones of the forearm.
Известен интрамедулл рный фиксатор дл костей предплечь в виде п тигранной призмы. П тиугольна форма поперечного сечени стержн обоснована каплевидной формой поперечника узкой части внутрико- стного канала костей предплечь . Однако данное устройство не обеспечивает надежной фиксации костных фрагментов.An intramedullary retainer for bones of the forearm is known in the form of a pigranium prism. The p-shaped cross-sectional shape of the rod is justified by the drop-shaped cross-section of the narrow part of the intraosseous canal of the forearm bones. However, this device does not provide reliable fixation of bone fragments.
Цель изобретени - повышение надежности фиксации.The purpose of the invention is to increase the reliability of fixation.
На фиг.1, 2 предствлено предлагаемое устройство.In figure 1, 2 presents the proposed device.
Устройство дл внутрикостного остео- синтезз костей предплечь выполнено в виде стержн с п тигранной частью 1, средней частью 2 пр моугольной формы и концом 3 цилиндрической формы. П тигранна часть 1 содержит п тое ребро Л противоположноеThe device for intraosseous osteosynthesis of bones of the forearm is made in the form of a rod with a polyhedral part 1, a middle part 2 of a rectangular shape and an end 3 of a cylindrical shape. P tigran part 1 contains the fifth edge of L opposite
основанию 5 с прилежащими пр мыми углами . П тигранна часть 1 дугообразно изогнута с вогнутостью по ребру 4, а средн часть 2 изогнута в плоскости, перпендикул рной плоскости изгиба п тигранной части 1.base 5 with adjacent right angles. The tigranic part 1 is curved arcuately with concavity along the rib 4, and the middle part 2 is curved in a plane perpendicular to the bend plane of the tigranic part 1.
Основание 5 п тигранной части 1 и прилежащие к нему грани 6, 7 совпадают соответственно с гран ми 8, 9, 10 пр моугольной средней части 2. Грани 11, 12 образующие ребро 4 посредством плавного изгиба переход т в грань 13 пр моугольной части.The base 5 of the tigranic part 1 and the adjacent faces 6, 7 coincide with the faces 8, 9, 10 of the rectangular middle part 2, respectively. The faces 11, 12 forming the edge 4 by smooth bending go into the face 13 of the rectangular part.
Устройство ввод т в кость предплечь . При этом дл предупреждени выпр млени естественной анатомической кривизны лучевой кости устройство перед введением изгибаетс согласно кривизне центральной анатомической оси внутрикостного канала в виде дуги с выпуклостью направленной кнаружи.The device is inserted into the forearm bone. At the same time, to prevent rectification of the natural anatomical curvature of the radius, the device is bent before insertion according to the curvature of the central anatomical axis of the intraosseous canal in the form of an arc with a convex outward.
