Description
Изобретение относится к медицинской технике, а йменно к протезостроению.The invention relates to medical equipment, and specifically to prosthetics.
Известен способ изготовления косметической облицовки протезов нижних конечностей путем получения полой формы пропитыванием трикотажного чулка, надетого на сохранившуюся конечность пациента, силиконовым каучуком и выворачиванием его после полимеризации с Ю последующим формированием облицовки[1] .A known method of manufacturing a cosmetic lining of prostheses of the lower extremities by obtaining a hollow form by impregnating a knitted stocking, worn on the patient’s remaining limb, with silicone rubber and turning it after polymerization with Yu followed by the formation of the lining [1].
Однако известный способ трудоемок, так как требует ручной доводки внутренней полости облицовки, увеличивая время технологического процесса.Кро- 15 ме того, у полученной облицовки нельзя сочетать такие свойства, как упругость и жесткость.However, the known method is laborious, since it requires manual refinement of the inner cavity of the cladding, increasing the time of the technological process. Moreover, the obtained cladding cannot combine such properties as elasticity and rigidity.
Цель изобретения — снижение трудоемкости изготовления, а также придание20 облицовке протеза упругости при одновременной жесткости.The purpose of the invention is to reduce the complexity of manufacturing, as well as giving 20 the lining of the prosthesis elasticity while rigidity.
Поставленная цель достигается тем, что при осуществлении способа изготовления облицовки протезов, полую форму 25 разрезают по длине, уменьшают по периметру до величины I = L - 2ίΈΗ, где L — первоначальный периметр формы, Н — толщина облицовочного материала; затем заливают в нее гипсовый раствор,30 при затвердевании которого получают позитив, снимают.в него полую форму, далее по позитиву обжимают предварительно нагретый облицовочный материал и удаляют позитив.This goal is achieved by the fact that when implementing the method of manufacturing prosthetic linings, the hollow mold 25 is cut in length, reduced along the perimeter to I = L - 2ίΈΗ, where L is the initial perimeter of the mold, H is the thickness of the facing material; then, a gypsum solution is poured into it, 30 during the solidification of which they receive a positive, they are removed. It is hollow in it, then the preheated facing material is pressed positively and the positive is removed.
Кроме того, в качестве облицовочного материала используют вспененный полиэтилен.In addition, foamed polyethylene is used as the facing material.
Способ осуществляется следующим образом.The method is as follows.
На' сохранившуюся конечность пациента надевают трикотажный чулок и пропитывают его силиконовым каучуком.A knitted stocking is put on the patient’s remaining limb and impregnated with silicone rubber.
Затем трикотажный чулок снимают с ноги инвалида путем выворачивания наизнанку и разрезают его вдоль. Затем уменьшают его в периметре с той целью, чтобы облицовочный материал, который будет затем наноситься, не выходил за пределы геометрических размеров здоровой конечности. В уменьшенную полость заливают гипсовый раст· вор, который после затвердевания образует уменьшенную копии) (позитив) отсутствующей конечности. Затем на эту копию кладут облицовочный материал в виде предварительно выкроенного вспененного полиэтилена, и блокуют по позитиву.Then the knitted stocking is removed from the leg of the disabled person by turning inside out and cut it lengthwise. Then it is reduced in the perimeter with the aim that the facing material, which will then be applied, does not go beyond the geometric dimensions of a healthy limb. A gypsum solution is poured into the reduced cavity, which, after hardening, forms a reduced copy) (positive) of the missing limb. Then on this copy lay the facing material in the form of a pre-cut foam polyethylene, and block it positively.
Использование метода уменьшения в периметре чехла, пропитанного силиконовым каучуком, сокращает время технологического процесса и не требует применения высококвалифицированного труда, а применение метода блокиров- $ ки вспененного полиэтилена позволяет получить косметическую облицовку улучшенных физико-механических свойств и уменьшить вес протеза.Using the reduction method in the perimeter of the case, impregnated with silicone rubber, reduces the time of the technological process and does not require the use of highly skilled labor, and the use of the method of blocking foamed polyethylene makes it possible to obtain a cosmetic lining with improved physical and mechanical properties and reduce the weight of the prosthesis.
