Erfindungsgemäß werden die Erfaßteile der Prothese, nachdem sie sich an den zu haltenden Gegenstand angeschmiegt haben, mittels * einer an einer Hebelübersetzung angreifenden Kraft unter Drehen in einem Preßgelenk an den Gegenstand gepreßt.The invention relates to a hand prosthesis. According to the invention, the detection parts the prosthesis after they have snuggled up to the object to be held, by means of * a force acting on a lever transmission while rotating in a press joint pressed against the object.

Auf der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes schema- tisch dargestellt.In the drawing, an embodiment of the subject matter of the invention is schematically table shown.

ι bezeichnet das Gehäuse der künstlichen Hand; an diesem sind mittels Gelenkachsen 2 und 3 der Daumen sowie die übrigen vier Finger angelenkt, von welch letzteren jedoch nur der Zeigefinger dargestellt ist. Die Glieder 4, 5 des Daumens und die Glieder 6, 7 der Finger sind durch eine Gelenkachse 8 bzw. 9 miteinander verbunden. An jedem Fingerglied ist konzentrisch zu seiner Gelenk achse eine Verzahnung 10 bis 13 befestigt, in die eine Schnecke 14 bis 17 eingreift. Die Wellen der Schnecken 14 und 15 sind in dem Mittelglied des Daumens bzw. Zeigefingers gelagert, während die Welle der Schnecke 16 im Handgehäuse gelagert ist: Die Welle der Schnecke 17 ist in einem Hebel 31' gelagert, der im Handgehäuse abgestützt ist. Auf jeder Schneckenwelle sitzen zwei kleine Rollen 18 bis 25 fest; über die Rollen x8, 20, 23 und 25 sind Schnüre gelegt, welche sämtlich mit einer Schnur 26 vereinigt sind. Diese Schnur ist durch eine Rolle 27 mit einem Zugorgan 28 verbunden, das zu einer willkürlich zu betätigenden Muskelkraftquelle führt. Die Schnüre sind so um die Rollen 18, 20, 23 und 25 gewickelt, daß, wenn die Schnur 28 nach unten gezogen wird, die Fingerglieder mit Hilfe der Schnecken und der in sie eingreifenden Verzahnungen geöffnet werden, d. h. in die gestreckte, Lage kommen. Wie schon erwähnt, sind auch die auf der Zeichnung nicht dargestellten Glieder der übrigen Finger mit Schnecken, zugehörigen Verzahnungen sowie Rollen und darüber gelegten Schnüren versehen, welch letztere mit der Schnur 28 verbunden sind; durch Ziehen an letzterer werden mithin außer dem Daumen und dem Zeigefinger auch die übrigen Finger der künstlichen Hand geöffnet.ι denotes the housing of the artificial hand; on this are by means of joint axes 2 and 3 the thumbs and the other four fingers articulated, but from which latter one only the index finger is shown. The limbs 4, 5 of the thumb and the limbs 6, 7 of the Fingers are connected to one another by a joint axis 8 and 9, respectively. On every phalanx A toothing 10 to 13 is attached concentrically to its joint axis, into which a worm 14 to 17 intervenes. The shafts of the augers 14 and 15 are in the middle link of the thumb or index finger stored, while the shaft of the worm 16 is stored in the hand housing is: The shaft of the worm 17 is mounted in a lever 31 ', which is in the hand housing is supported. Two small rollers 18 to 25 are firmly seated on each worm shaft; above the rollers x8, 20, 23 and 25 are cords, which are all united with a cord 26 are. This cord is connected by a roller 27 to a pulling element 28, which leads to an arbitrarily operated source of muscle power leads. The cords are wrapped around rollers 18, 20, 23 and 25 in such a way that, when the cord 28 is pulled down, the phalanges of the fingers with the help of the snails and the teeth engaging in them are opened, d. H. get into the stretched position. As already mentioned, the links not shown in the drawing are also the remaining links Fingers with worms, associated teeth, as well as rollers and overlaid Laces provided, the latter being connected to the cord 28; by pulling on In addition to the thumb and index finger, the other fingers also become the latter the artificial hand opened.

Über die Rollen 19, 21, 22 und 24 sind ebenfalls Schnüre gewickelt, deren eine Enden an den betreffenden Rollen, die anderen dagegen an Federn 29 bis 32 befestigt sind, die selbst wieder an den betreffenden Gliedern bzw. am Handgehäuse befestigt sind.About the roles 19, 21, 22 and 24 are also Cords wound, one end to the relevant pulley, the other against it are attached to springs 29 to 32, which themselves again on the relevant links or on Hand housing are attached.

Der Wicklungssinn der um die zuletztgenannten Rollen gelegten Schnüre ist demjenigen der um die Rollen 18, 20, 23 und 25 gelegten Schnüre entgegengesetzt, so daß beim Abwärtszuge der Schnüre 28, 26 die um die Rollen 19, 21, 22 und 24 gelegten Schnüre auf letztere aufgewickelt und die mit ihnen verbundenen Federn gespannt werden.The sense of winding the cords placed around the last-mentioned rollers is that opposed to the cords placed around the rollers 18, 20, 23 and 25, so that when Downward pulling of the cords 28, 26 on the cords placed around the rollers 19, 21, 22 and 24 the latter are wound up and the springs connected to them are tensioned.

Der bereits erwähnte Hebel 31' liegt mit seinem unteren Ende an einem Arme 37 eines Winkelhebels 37, 38; der Arm 38 ist durch eine Schnur 39 mit einer Muskelkraftquelle verbunden.The already mentioned lever 31 'lies with its lower end on an arm 37 of one Angle lever 37, 38; the arm 38 is connected to a muscular power source by a cord 39 tied together.

Das obere Ende des Hebels 31' trägt mit-The upper end of the lever 31 'carries with

tels eines seitlichen Fortsatzes 34 die Gelenkachse 3 des Zeigefingers, so daß durch entsprechendes Drehen jenes Hebels 31/ der ganze Zeigefinger mehr oder weniger um das Preßgelenk 36 gedreht werden kann, und zwar mit übersetzter Kraft.means of a lateral extension 34, the hinge axis 3 of the index finger, so that by corresponding Turn that lever 31 / the whole index finger more or less around the press joint 36 can be rotated, with translated force.

Die Wirkungsweise des Handersatzes ist folgende:The mode of action of the hand replacement is as follows:

Für gewöhnlich sind die Finger geschlossen.Usually the fingers are closed.

Um einen Gegenstand, z. B. einen Hammerstiel, zu erfassen, übt der Amputierte willkürlich einen Zug im Sinne des Pfeiles I auf die Schnüre 28 und 26 aus, wodurch, wie schon früher erwähnt ist, die sämtlichen Finger geöffnet und die Federn 29, 30, 31 und 32 gespannt werden.To an object, e.g. B. to grasp a hammer handle, the amputee exercises arbitrarily a train in the direction of arrow I on the cords 28 and 26, whereby, as before is mentioned earlier, all fingers are open and the springs 29, 30, 31 and 32 are stretched will.

Nachdem der zu erfassende Gegenstand in die Hand gelegt worden ist, läßt der Amputierte die Zugwirkung auf die Schnur 28 aufhören; die Federn 29 bis 32 entspannen sich dann und bewirken mit Hilfe der beim Öffnen der Hand auf die Rollen 19, 21, 22, 24 gewickelten Schnüre das Schließen der Finger, soweit es der erfaßte Gegenstand zuläßt. Es wird hier darauf hingewiesen, daß die Schließbewegungen der einzelnen Finger ganz voneinander unabhängig sind, mithin sich jeder Finger der Form des zu ergreifenden Gegenstandes anschmiegen kann. Nachdem dies erfolgtest, übt der Amputierte auf die Schnur 39 einen Zug, aus, wodurch mittels des Hebels 37, 38 der Hebelarm 31' um den Punkt 36 gedreht wird und so mit Hilfe des Fortsatzes 34 die Achse 3 nach innen geschwungen wird, mit der Wirkung, daß mit Ausnahme des Daumens alle Finger mit ins Starke übersetzter Kraft gegen den Gegenstand bzw. gegen den Daumen hin gepreßt werden.After the object to be grasped has been placed in the hand, the amputee leaves cease pulling the cord 28; springs 29 to 32 relax then and effect with the help of the rolls 19, 21, 22, 24 wound onto the rollers 19, 21, 22, 24 when the hand is opened Cord the closing of the fingers as far as the grasped object allows. It is pointed out here that the closing movements of the individual fingers are completely independent of one another, so that each finger follows the shape of the object to be grasped can hug. After this has been done, the amputee exercises on the cord 39 a train, whereby the lever arm 31 'is rotated about the point 36 by means of the lever 37, 38 is and so with the help of the extension 34 the axis 3 is swung inward, with the effect that, with the exception of the thumb, all fingers are translated into strength Force against the object or against the thumb to be pressed.

Auf diese Art wird ein kräftiges Festhalten des Gegenstandes durch die Finger erzielt. Ein selbsttätiges öffnen der letzteren ist ausgeschlossen, indem die an den Fingern befestigten Verzahnungen durch die zugehörigen Schnecken in ihren Lagern gesperrt werden· und die Federn 29 bis 32 die Schnecken so zu drehen suchen, daß die Einger geschlossen werden.In this way, the object is held firmly by the fingers. An automatic opening of the latter is impossible because they are attached to the fingers Toothings are locked by the associated worms in their bearings · and the springs 29 to 32 close the worms turn to seek that the fingers are closed.
