Abstract

Протез нижней конечности относитс  к медицинской технике, а именно, к протезам нижних конечностей дл  инвалидов. Цель изобретени  - снижение энергозатрат инвалида при ходьбе за счет приближени  кинематики протеза в фазе переноса к движению здоровой конечности. Протез нижней конечности содержит гильзу 1 бедра и гильзу голени, состо щую из двух частей: проксимальной 2 и дистальной 3 телескопических трубок. Гильза бедра и проксимальна  трубка соединены между собой с помощью шарнира 4. К гильзе бедра сзади оси шарнира 4 подсоединен шарнирно-упругий элемент, выполненный в виде телескопически подпружиненного звена, включающего телескопическую трубки 5 и 6 и пружину 7. Второй конец упругого элемента шарнирно св зан с рычагом 8, с которым жестко соединен коленный стопорный механизм, включающий храповое колесо 9 и собачку 10. Оси храпового колеса и собачки св заны с проксимальной трубкой 2 гильзы голени. Собачка 10 посредством подпружиненной т ги 11 проксимальной телескопической трубки 2 соединена с дистальной трубкой 3. К дистальной трубке 3 гильзы голени присоединена щиколотка 12, к которой с помощью шарнира 13 присоединена стопа 14. Со стопой жестко св зано храповое колесо 15 голеностопного стопорного механизма. Собачка 16 голеностопного стопорного механизма св зана посредством жесткой подпружиненной т ги 17 дистальной телескопической трубки 3 с проксимальной телескопической трубкой 2. Между щиколоткой 12 и стопой 14 сзади шарнира 13 стопы размещена пружина 18. 1 ил.The prosthesis of the lower limb relates to medical technology, namely, the prosthetic lower limb for the disabled. The purpose of the invention is to reduce the energy consumption of a disabled person when walking due to the approach of the kinematics of the prosthesis in the transfer phase to the movement of a healthy limb. The lower limb prosthesis contains a sleeve of the thigh and a sleeve of the lower leg consisting of two parts: the proximal 2 and the distal 3 telescopic tubes. The thigh sleeve and proximal tube are interconnected by means of a hinge 4. A hinge-elastic element made in the form of a telescopically spring-loaded link including a telescopic tube 5 and 6 and a spring 7 are connected to the thigh sleeve at the rear of the axis of the hinge 4 and the second end of the elastic element is hinged with a lever 8, with which a knee locking mechanism is rigidly connected, including a ratchet wheel 9 and a dog 10. The axes of the ratchet wheel and dog are connected with the proximal tube 2 of the shin sleeve. The pawl 10 is connected via a spring-loaded rod 11 of the proximal telescopic tube 2 to the distal tube 3. An ankle 12 is attached to the distal tube 3 of the shin sleeve, to which is attached a hinge 13 to the foot 14. A ratchet wheel 15 of the ankle locking mechanism is rigidly connected. The dog 16 of the ankle locking mechanism is connected by means of a rigid spring-loaded rod 17 of the distal telescopic tube 3 with a proximal telescopic tube 2. A spring 18 is placed between the ankle 12 and the foot 14 behind the hinge 13 of the foot. 1 Il.

Второй конец упругого элемента шарнирно связан с рычагом 8, с которым жестко соединен коленный стопорный механизм, включающий храповое колесо 9 и собачку 10. Оси храпового колеса и собачки связаны с проксимальной трубкой 2 гильзы голени. Собачка 10 посредством подпружиненной тяги 1 1 проксимальной телескопической трубки 2 соединена с дистальной трубкой 3. К дистальной трубке 3 гильзы голени присоединена щиколотка 12, к которой с помощью шарнира 13 присоединена стопа 14. Со стопой жестко связано храповое колесо 15 голеностопного стопорного механизма. Собачка 16 голеностопного стопорного механизма связана посредством жесткой подпружиненной тяги 17 дистальной телескопической трубки 3 с проксимальной телескопической трубкойThe lower limb prosthesis refers to medical equipment, namely to lower limb prostheses for the disabled. The purpose of the invention is to reduce the energy consumption of a disabled person when walking due to the approximation of the kinematics of the prosthesis in the transfer phase to the movement of a healthy limb. The prosthesis of the lower limb contains a sleeve 1 of the thigh and a sleeve of the lower leg, consisting of two parts: proximal 2 and distal 3 telescopic tubes. The thigh sleeve and the proximal tube are interconnected using a hinge 4. A hinge-elastic element made in the form of a telescopically spring-loaded link including telescopic tubes 5 and 6 and a spring 7 is connected to the thigh sleeve behind the axis of the hinge 4. The second end of the elastic element is pivotally connected to the lever 8, to which a knee locking mechanism is rigidly connected, including a ratchet wheel 9 and a dog 10. The axles of the ratchet wheel and a dog are connected to the proximal tube 2 of the lower leg sleeve. The dog 10 is connected by a spring rod 1 1 of the proximal telescopic tube 2 to the distal tube 3. An ankle 12 is attached to the distal tube 3 of the lower leg sleeve, to which the foot 14 is attached using the hinge 13. The ratchet wheel 15 of the ankle stop is rigidly connected to the foot. The dog 16 of the ankle locking mechanism is connected by means of a rigid spring-loaded rod 17 of the distal telescopic tube 3 with the proximal telescopic tube 2. Между щиколоткой 12 и стопой 14 сзади шарнира 13 стопы размещена пружина 18. 1 ил.2. Between the ankle 12 and the foot 14 at the back of the hinge 13 of the foot is a spring 18. 1 ill.
