Изобретение относитс к области медицины , в частности к протезированию.This invention relates to the field of medicine, in particular to prosthetics.
Известен способ управлени протезом с внешним источником энергии, при котором в качестве источника управл ющих сигналов используют контактный датчик, установленный непосредственно на протезе 1.A known method of controlling a prosthesis with an external energy source, in which a contact sensor mounted directly on the prosthesis 1 is used as a source of control signals.
Однако при смеп1,ении протеза, неизбежно возникающем при работе им, относительно мышечного канала может происходить самопроизвольное срабатывание датчика, а повышение помехозащитности путем увеличени усили , необходимого дл срабатывани датчика , ведет к чрезмерной нагрузке на стенки мышечного канала и не позвол ет использовать ослабленные мышцы культей.However, when the prosthesis inevitably arises when working with it, relative to the muscular canal, spontaneous sensor activation may occur, and increased noise immunity by increasing the force required to trigger the sensor leads to excessive stress on the walls of the muscular canal and prevents the use of weakened muscles .
Целью изобретени вл етс исключение ложных срабатываний протеза, а также возможность использовани ослабленных мышЦ культей конечностей дл управлени протезом . Это достигаетс тем, что создают оперативным путем мышечный канал, в который помещают датчик, например контактный, и соедин ют датчик с электроприводом протеза .The aim of the invention is the elimination of false positives of the prosthesis, as well as the possibility of using the weakened muscles of the stump of the limbs to control the prosthesis. This is achieved by creating operatively the muscular canal into which the transducer is placed, for example a contact channel, and the transducer is connected to the prosthesis electrically.
На фиг. 1 показано расположение датчика и протеза на инвалиде; на фиг. 2 изображен датчик.FIG. 1 shows the location of the sensor and prosthesis on the disabled; in fig. 2 shows a sensor.
Датчик 1, погруженный в канал, электрически соединен с электронным блоком 2 управлени , св занным с источником 3 питани и искусственной кистью 4 с электроприводом . Блок управлени и искусственна кисть закреплены на протезе 5, датчик не имеет 5 жесткого соединени с протезом.A sensor 1 immersed in a channel is electrically connected to an electronic control unit 2 connected to a power source 3 and an electric motorized brush 4. The control unit and the artificial brush are fixed on the prosthesis 5, the sensor does not have 5 rigid connections with the prosthesis.
Датчик содержит пружин щий пинцет 6, закрепленный на плате 7, на которой расположены микропереключатели 8 и 9, закрытые крышкой 10.The sensor contains spring tweezers 6, mounted on the board 7, on which microswitches 8 and 9 are located, closed by a cover 10.
0 В исходном положении кнопка микропереключател 8 нажата свободным концом пружин щего пинцета 6.0 In the initial position, the microswitch button 8 is pressed with the free end of the spring forceps 6.
Управл ют протезом следующим образом. Пинцет погружают в образованный опера5 тпвным путем мышечный канал. При сужении канала свободный конец пинцета начинает перемещатьс , при этом сначала отпускаетс кнопка микропереключател 8, а затем нажимаетс кнопка микропереключател 9. Спгнал с микропереключателей поступает на электронный блок 2 управлени . Он реализует заданный алгоритм управлени , например познционпо-скоростной, при котором быстрому сжатию пинцета до сра5 батыванн микропереключател 9 соответствует включение электропривода кисти на раскрытие, а медленному - на схват.The prosthesis is controlled as follows. The tweezers are immersed in the muscular canal formed by the operative. When the channel is narrowed, the free end of the tweezers begins to move, first the microswitch button 8 is released, and then the microswitch button 9 is pressed. The microswitch signal goes to the electronic control unit 2. It implements a predetermined control algorithm, for example, position-speed, in which the quick compression of the tweezers to the right side of the microwatch 9 corresponds to switching on the brush electric drive for opening, and slower for gripping.
Использование предлагаемого способа управлени протезом с внешнпм источникомUsing the proposed method of controlling a prosthesis with an external source
о энергии приводит к исключению самопроизвольных срабатываний датчика при смещени х протеза относительно культи, получению возможности использовани дл управлени ослабленных мышц культей конечностей .Energy leads to the elimination of spontaneous sensor actuation when the prosthesis is biased relative to the stump, and can be used to control the weakened muscles of the stumps of the limbs.
