Description

Изобретение относитс  к медицинской технике , а именно к протезам верхних конечностей . Известен привод, содержаш,ий т говый механизм в виде сектора с т гой и собачки, и разгрузочный механизм с упругим элементом. Однако в этом приводе при сгибании - разгибании протезированной конечности требуетс  больша  величина моментов мышечных сил. Целью изобретени   вл етс  создание устройства , облегчающего управление протезом. Дл  этого в приводе установлены электродвигатель , микропереключатели, механический пороговый элемент и самотормоз ща с  винтова  передача, к гайке которой прикреплен конец упругого элемента разгрузочного механизма, электродвигатель кинематически св зан с винтом самотормоз щейс  передачи, а механический пороговый элемент выполнен в виде пружины, например пластинчатой, и блока управлени  с микропереключател ми пр мого и обратного вращени  вала электродвигател , последовательно соединенными с микропереключател ми крайних положений гайки самотормоз щейс  передачи и микропереключателем , установленным в пальцах кисти протеза. Иа чертеже изображена принципиальна  схема привода. Он содержит электродвигатель 1, кинематически св занный с винтом 2 самотормоз щейс  передачн, гайка 3 которой св зана с концом упругого элемента 4 разгрузочного мехаппзма. Привод снабжен т говым механизмом в виде сектора 5 с т гой 6 и собачки 7, механическим пороговым элементом, выполненным в виде пружины 8, например, пластинчатой, и блоком управлени  с микропереключател ми 9 пр мого и 10 обратного вращени  вала электродвигател  1, последовательно соединенными с микропереключател ми 11 и 12 крайних положений гайки 3 самотормоз щейс  передачи и микропереключателем 13, установленным в пальцах кисти протеза. Привод работает следующим образом. При захвате кистью предмета срабатывает микропереключатель 13. Последующий подъем дистального звена протеза осуществл етс  за счет усили , прпкладываемого к т ге 6. Если это усилие превышает пороговую величину , задаваемую жесткостью пружины 8, собачка 7 поворачиваетс  вокруг оси 14, включа  микропереключатели 9 пр мого вращени . Включаетс  электродвигатель 1, и упругий элемент 4 разгрузочного механизма начинает раст гиватьс , получа  энергию через винтовую самотормоз щуюс  передачу. Увеличение момента, создаваемого унругим элементом 4 относительно оси 15, продолжаетс  до тех пор, пока не выравн ютс  значени The invention relates to medical technology, namely to upper limb prostheses. The drive is known to contain a traction mechanism in the form of a sector with a thrust and a pawl, and an unloading mechanism with an elastic element. However, in this drive, when bending - unbending the prosthetic limb, a large amount of muscular strength moments is required. The aim of the invention is to provide a device that facilitates the management of the prosthesis. To do this, an electric motor, microswitches, a mechanical threshold element and a self-brake with a screw gear are installed in the drive, to the nut of which the end of the elastic element of the unloading mechanism is attached, the electric motor is kinematically connected with the screw of the automatic brake gear, and the mechanical threshold element is designed as a spring, for example a plate-type , and a control unit with microswitches for direct and reverse rotation of an electric motor shaft connected in series with microswitches of extreme positions rd nut samotormoz scheys transmission and a microswitch installed in the fingers of the prosthesis brush. The drawing shows a schematic diagram of the drive. It contains an electric motor 1, kinematically connected with the screw 2 of a self-braking gear, the nut 3 of which is connected with the end of the elastic element 4 of the unloading mechanism. The drive is equipped with a traction mechanism in the form of a sector 5 with a tension of 6 and a pawl 7, a mechanical threshold element made in the form of a spring 8, for example, a plate-like one, and a control unit with microswitches 9 for direct and 10 reverse rotation of the shaft of an electric motor 1 connected in series with microswitches 11 and 12 of the extreme positions of the nut 3 self-braking transmission and microswitch 13 installed in the fingers of the prosthesis. The drive works as follows. When the object is gripped by the brush, microswitch 13 is triggered. Subsequent lifting of the distal prosthesis link is carried out due to the force applied to the rod 6. If this force exceeds the threshold value specified by the spring stiffness 8, the pawl 7 rotates around the axis 14, turning the microswitches 9 forward rotation . The electric motor 1 is turned on, and the elastic element 4 of the unloading mechanism begins to stretch, receiving energy through a screw self-braking transmission. The increase in the moment created by the external element 4 about the axis 15 continues until the values
