Description

Изобретение относитс  к области протезостроени , в частности к искусственным кист м дл  протезов.The invention relates to the field of prosthesis, in particular to artificial cysts for prostheses.

Известны искусственные кисти дл  протезов , содержащие корпус, гибкую т гу и механизм схвата в виде двуплечих рычагов, первого и блока второго-п того пальцев, и фиксатора, недостатком которых  вл етс  значительна  выборка т ги при управлении протезом, а также возрастание усили  на т ге по мере раскрыти  пальцев кисти.Artificial brushes for prostheses are known, comprising a body, a flexible pull and a gripper mechanism in the form of double-arm levers, a first and second to fifth fingers block, and a latch, the disadvantage of which is a large selection of thrust when controlling the prosthesis, as well as Ge as you open your fingers.

Предлагаема  искусственна  кисть отличаетс  от известных тем, что первый и блок второго-п того пальцев соединены посредством промежуточного звена, па оси корпуса установлен направл ющий ролик под т гу, закрепленную на первом пальце, пружина выполнена винтовой и помещена между осью ролика и блоком второго-п того пальцев, а фиксатор кинематически св зан с т гой. Такое выполнение искусственной кисти позвол ет уменьшить усилие и величину выборки т ги при раскрытии пальцев и фиксации их в исходном положении .The proposed artificial brush differs from the known ones in that the first and second-to-fifth fingers are connected by means of an intermediate link, a guide roller is mounted under the axle of the body, mounted on the first finger, the spring is screwed and placed between the roller axis and the second- fingers, and the latch is kinematically connected to the thy. Such an embodiment of an artificial brush makes it possible to reduce the force and size of the hauling sample when opening the fingers and fixing them in the initial position.

На чертеже изображена предлагаема  кисть дл  протезов, в двух проекци х.The drawing shows the proposed brush for prostheses in two projections.

Искусственна  кисть содержит корпус /, ось 2 на рычаге 3 первого пальца, который вращаетс  вокруг оси , блок 5 второго-п то. го пальцев с осью 6, промежуточное звено 7,The artificial brush comprises a housing /, axis 2 on the lever 3 of the first finger, which rotates around an axis, block 5 of the second-n. th fingers with axis 6, intermediate 7,

ось 8 вращени  блока 5 второго-п того пальцев , винтовую пружину 9, направл ющий ролик 10 на оси 11, фиксатор 12 с пружиной 13 на оси 14. С фиксатором кинематически св зана гибка  т га 15, закрепленна  на рычаге 3 первого пальца. Винтова  пружина 9 помещена между осью 11 с роликом 10, по которому проходит т га 15, и блоком 5 второго- п того пальцев.axis 8 of rotation of block 5 of second to fifth fingers, helical spring 9, guide roller 10 on axis 11, clamp 12 with spring 13 on axle 14. With clamp the kinematically connected bend 15, fixed on lever 3 of the first finger. The screw spring 9 is placed between the axis 11 with the roller 10, through which the ha goes 15, and the block 5 of the second and fifth fingers.

Работа искусственной кисти осуществл етс  следующим образом.The operation of the artificial brush is carried out as follows.

При воздействии на гибкую т гу 15 фиксатор 12, прикрепленный к ней, поворачиваетс  вокруг оси 14 и освобождает рычаг 3 первогоWhen acting on the flexible cable 15, the retainer 12 attached to it rotates around the axis 14 and releases the lever 3 of the first

пальца. Этот рычаг поворачиваетс  вокруг оси 4, увлека  за собой промежуточное звено 7, шарнирно соединенное с блоком 5 второго-п того пальцев, который поворачиваетс  вокруг оси 8 в противоположном направлении,fingertips. This lever rotates around axis 4, dragging along intermediate link 7, pivotally connected to block 5 of second or fifth fingers, which rotates around axis 8 in the opposite direction,

и пальцы раскрываютс . При расслаблении гибкой т ги механизм перемещаетс  в обратном направлении под действием пружины 9, пальцы закрываютс , осуществл етс  схват. Фиксатор вместе с т гой возвращаетс  в исходное положение, фиксиру  рычаг 3 первого пальца. Фиксатор установлен так, что в исходном положении (схват) угол между ним и рычагом 3 составл ет приблизительно 90-135°. Предмет изобретени and fingers open. When the flexible thrust is relaxed, the mechanism moves in the opposite direction under the action of the spring 9, the fingers are closed, the gripper is realized. The latch together with the thrust returns to its original position, locking the lever 3 of the first finger. The locking mechanism is set so that in the initial position (gripper) the angle between it and the lever 3 is approximately 90 ° -135 °. Subject invention
