Description
Изобретение относится к области медицинской техники, а именно, к протезированию и протезост.роению.The invention relates to the field of medical equipment, namely, prosthetics and prosthetics.
Известен способ изготовления металли- 5 ческих приемных гильз протезов конечностей, включающий формирование гипсовой матрицы-негатива культи, изготовление трубчатой заготовки по развертке вписанного в матрицу конуса или цилиндра, свар- 10 ку заготовки, размещение ее в матрице и воздействие на заготовку энерпией импульсного источника (1].A method for manufacturing a metallic receiving sleeves 5 iCal limb prosthesis comprising forming a gypsum matrix-negative stump of the tubular preform by the matrix scan inscribed in a cone or cylinder, 10 svar- ku preform, placing it in the matrix and the effect on the pulsed source of energy of the workpiece ( 1].
Недостатком известного способа являет- 15 ся трудоемкость операций и не точное соответствие формы гильзы анатомическому строению культи сложной конфигурации.A disadvantage of the known method yavlyaet- 15 Xia complexity of operations and do not form an exact match of the sleeve anatomy stump complex configuration.
Целью изобретения является получение длинномерных гильз, точно повторяющих 20 анатомическое строение культи в случае ее сложного строения по длине.The aim of the invention is to obtain long sleeves that accurately repeat the 20 anatomical structure of the stump in the case of its complex structure in length.
Указанная цель достигается тем, что трубчатую заготовку формируют в виде не- 25 скольких конусов различной конусности или цилиндров разного диаметра, размещают их в матрице один над другим, воздействие энергией импульсного источника проводят последовательно, начиная с ниж- 30 ней заготовки, а затем сваривают отформованные заготовки по стыкам между собой.This goal is achieved by the fact that the tubular billet is formed in the form of several 25 cones of different tapers or cylinders of different diameters, they are placed in the matrix one above the other, exposure to the energy of the pulse source is carried out sequentially, starting from the bottom 30 of the billet, and then molded are welded blanks at the joints between each other.
На фиг. 1—4 показаны различные этапы осуществления способа.In FIG. 1-4, the various steps of the method are shown.
Способ изготовления приемных гильз осуществляют следующим образом.A method of manufacturing a receiving sleeve is as follows.
С культи инвалида получают гипсовую матрицу -негатив (фиг. 1), например, путем окунания культи 1 с чехлом 2, толщина которого равна толщине материала заготовки, в полужидкий гипс 3, помещенный в металлическую емкость 4. После остывания гипса 3 'внутренняя полость полученной гипсовой матрицы-негатива полностью соответствует анатомическому строению культи.From the stump of a disabled person, a negative gypsum matrix is obtained (Fig. 1), for example, by dipping the stump 1 with a cover 2, the thickness of which is equal to the thickness of the workpiece, in semi-liquid gypsum 3, placed in a metal container 4. After cooling the gypsum 3 ', the inner cavity of the obtained the gypsum negative matrix is fully consistent with the anatomical structure of the stump.
По развертке вписываемых в снятую гипсовую матрицу-негатив конусов разной конусности или цилиндров изготавливают из металлического листа путем сварки, например, кислородно-ацетиленовой трубчатые заготовки 5, которые вставляют внутрь матрицы-негатив а (фиг. 2).According to the scan, cones of different tapers or cylinders inserted into the removed gypsum-negative matrix are made of a metal sheet by welding, for example, oxygen-acetylene tubular blanks 5, which are inserted into the negative matrix a (Fig. 2).
В полость заготовок 5 вставляют емкость 6, например, из тонкостенного полиэтилена, заполненного гидросредой 7, затем опускают детонационно-газовый источник 8 •до уровня .нижней заготовки 5. Генерируют ударную волну, которая штампует нижнюю заготовку по поверхности матрицы-негатива (фиг. 3).A container 6 is inserted into the cavity of the blanks 5, for example, of thin-walled polyethylene filled with a hydraulic medium 7, then the detonation-gas source 8 • is lowered to the level of the lower blank 5. A shock wave is generated that stamps the lower blank on the surface of the negative matrix (Fig. 3 )
Затем перемещают источник 8 до уровня верхней заготовки 5. Снова генерируют ударную волну, которая штампует верхнюю заготовку и стык верхней и нижней заготовок (фиг. 4). После формовки заготовок 5 их вынимают из полости матрицы и свари· вают обе заготовки по поперечному стыку, например, кислородно-ацетиленовой сваркой встык.Then the source 8 is moved to the level of the upper workpiece 5. Again, a shock wave is generated, which stamps the upper workpiece and the joint of the upper and lower workpieces (Fig. 4). After forming the blanks 5, they are removed from the die cavity and both blanks are welded along the transverse joint, for example, by butt-welding with oxygen-acetylene.
Таким образом, использование предлагаемого способа изготовления приемных металлических гильз протезов конечностей обеспечивает следующие преимущества: возможность получения длинномерных приемных гильз сложной конфигурации, точно повторяющих анатомическое строение культи инвалида; исключение ручной индивидуальной подгонки приемных гильз; время, затрачиваемое на штамповку одной гильзы со всеми подготовительными операциями составляет 2 .мин, на получение одной___матрицы-слепка не более 20— мин; стоимость протезов уменьшается на 50—60%.Thus, the use of the proposed method for the manufacture of receiving metal sleeves of prosthetic limbs provides the following advantages: the ability to obtain long receiving sleeves of complex configuration, exactly repeating the anatomical structure of the stump of a disabled person; the exception of manual individual adjustment of the receiving sleeves; the time spent on stamping one sleeve with all the preparatory operations is 2 .min, to get one ___ impression matrix is not more than 20 min; the cost of prostheses is reduced by 50-60%.
