Изобретение относитс к медицинской технике.The invention relates to medical technology.
Известно устройство дл нормализации кинематики движений звеньев протеза нижней конечности, содержащее гильзу бедра, балансировочный груз, неподвижно укрепленный на гильзе голени протеза с возможностью регулировки его положени , и коленный шарнир 1.A device for normalizing the kinematics of movements of lower limb prosthesis links, comprising a femoral sleeve, a balancing weight fixed on the lower leg of the prosthesis with the possibility of adjusting its position, and a knee hinge 1 are known.
Однако такое устройство не позвол ет измен ть период колебаний в процессе шага, кроме того, оно требует больших энерготрат .However, such a device does not allow to change the period of oscillations in the step process, in addition, it requires a large amount of energy.
Цель изобретени - обеспечение возможности изменени периода колебаний в процессе шага и уменьшение энерготрат.The purpose of the invention is to provide the possibility of changing the oscillation period in the step process and reducing energy consumption.
Дл этого в предлагаемое устройство введены шток, соединенный с балансировочным грузом посредством резьбового соединени , и шатун с осью, котора размеш,ена в пазу гильзы бедра с возможностью ее фиксации с различными эксцентриситетами относительно оси коленного шарнира.For this, a rod, connected to the balancing weight by means of a threaded joint, and a connecting rod with an axis that is placed in the groove of the thigh sleeve with the possibility of its fixation with different eccentricities relative to the axis of the knee joint are inserted into the proposed device.
На чертеже схематично изображено предлагаемое устройство дл нормализации движений звеньев протеза бедра, обший вид в разрезе.The drawing schematically shows the proposed device for the normalization of the movements of the links of the hip prosthesis, a general view in section.
Устройство содержит гильзу 1 бедра, гильзу 2 голени, шток 3, соединенный с балансировочным грузом 4 посредством резьбового соединени , шатун 5 с осью 6, котора размешена в пазу гильзы 1 бедра, коленный шарнир 7.The device comprises a thigh sleeve 1, a shank sleeve 2, a rod 3 connected to the balancing weight 4 by means of a threaded connection, a connecting rod 5 with an axis 6 which is placed in the groove of the thigh sleeve 1, a knee joint 7.
Устройство работает следующим образом.The device works as follows.
При сгибании протеза бедра относительно оси коленного шарнира 7 в переносный период шага балансировочный груз 4, св занный с гильзой 1 бедра шатуном 5, штоком 3 и ос ми 8 и 6, перемещаетс в проксимальном направлении на заданное рассто ние, что обеспечивает требуемое изменение инерционных характеристик протеза бедра дл нормализации периода колебаний протезированной конечности.When the hip prosthesis is bent relative to the axis of the knee joint 7, the balancing weight 4 connected to the thigh sleeve 1 by the connecting rod 5, rod 3 and axes 8 and 6 moves in the proximal direction by a predetermined distance during the portable period of the step, providing the required inertial characteristics hip prosthesis to normalize the period of oscillation of the prosthetic limb.
Корректировку исходного положени балансировочного груза производ т следующим образом: протез бедра огибают относительно оси коленного щарнира 7, вынимают ось 6, освобожда щатун 5, поворотом щатуна и щтока 3 балансировочный груз 4 перемещают вверх и вниз, причем вращению его вместе со штоком 3 преп тствует ограничитель 9 поворота.The initial position of the balancing weight is adjusted as follows: the hip prosthesis bends around the axis of the knee joint 7, the axis 6 is removed, releasing the rod 5, turning the rod and the stem 3, the balancing weight 4 is moved up and down, and the limiter prevents it from rotating with the stem 3. 9 turns.
Исследовани и практическое протезирование показали, что применение устройства дл нормализации рисунка ходьбы инвалида на протезе бедра позволило получить изменени периода колебаний и максимальных значений коленного угла как на протеStudies and practical prosthetics have shown that using a device for normalizing the walking pattern of a disabled person on a hip prosthesis allowed us to obtain changes in the oscillation period and maximum values of the knee angle as per the
