Description

Die Erfindung betrifft ein künstliches Fußgelenk, welches in seiner Bewegung durch eine hydraulische Dämpfwirkung beeinflußt wird. Bislang waren Fußprothesen mit Gummipuffern oder Federn ausgestattet, die wohl auch die Bewegung dämpfen, aber einen harten unausgeglichenen Gang nicht vermeiden konnten. Sie hatten weiterhin den großen Nachteil, daß der Fuß sofort in seine Mittellage zurückschnellte, sobald die Belastung durch das Anheben der Prothese entzogen wurde. Es ist jedoch für den Prothesenträger außerordentlich wichtig, daß der Fuß in derselben Stellung wieder auf den Boden auftritt, wie er diesen verlassen hat. The invention relates to an artificial ankle, which in his Movement is influenced by a hydraulic damping effect. So far there were prosthetic feet equipped with rubber buffers or springs, which probably also dampen the movement, but could not avoid a hard, unbalanced gait. They continued to have the great disadvantage that the foot immediately snapped back into its central position as soon as the load has been removed by lifting the prosthesis. However, it is for that It is extremely important for prosthesis wearers that their feet are in the same position again occurs on the floor as he has left it.

Zum Beispiel beim Vorwärtslaufen geht die Fußspitze vorn hoch, wenn der Fuß den Boden verläßt.For example, when running forward, the toe goes up in front, if the foot leaves the ground.

In derselben Stellung, mit Fußspitze hoch und Absatz unten, muß er auf den Boden aufsetzen, wie dies beim natürlichen Gang mit einem gesunden Fuß auch der Fall ist. Dies ist durch nachbeschriebene Einrichtung möglich und wird hierbei außerdem erreicht, daß die Bewegung als solche durch den Öldruck gedämpft wird.In the same position, with toe up and heel down, he must Sit down on the floor, as you would when walking naturally with a healthy foot the case is. This is possible by means of the facility described below and will be used here also achieved that the movement as such is dampened by the oil pressure.

Die Zeichnung zeigt einen senkrechten Mittelschnitt durch das künstliche Fußgelenk. An dem künstlichen Unterschenkel I ist in bekannter Weise der Fuß 2 im Mittelpunkt 3 angelenkt. In den Fuß sind zwei oder mehr Zylinder 4 eingelassen, in welchen Kolben 5 bewegt werden. Diese Kolben 5 stehen durch Pleuelstangen 6 mit dem Unterschenkel I in Verbindung. Je nach Stellung des Unterschenkels I werden die Kolben 5 gehoben oder gesenkt und damit das in den unteren Teilen der Zylinder 4 befindliche Öl 7 durch das Verbindungsrohr 8 von einem Zylinder in den anderen gedriickt. The drawing shows a vertical center section through the artificial one Ankle. On the artificial lower leg I, the foot 2 is in a known manner Center 3 hinged. Two or more cylinders 4 are embedded in the foot, in which piston 5 are moved. These pistons 5 are connected by connecting rods 6 the lower leg I in connection. Depending on the position of the lower leg I will be the pistons 5 are raised or lowered, and thus that in the lower parts of the cylinders 4 located oil 7 through the connecting pipe 8 from one cylinder to the other pressed.

An einer von außen leicht zugänglichen Stelle ist in das Ölrohr 8 eine Drossel 9 eingebaut, mittels welcher die Durchlaufgeschwindigkeit geregelt werden kann. Durch diese regelhare Einrichtung wird ein sehr sanfter Gang bei einem Kunstbein erzielt.The oil pipe 8 is located at a point that is easily accessible from the outside a throttle 9 installed, by means of which the throughput speed is regulated can be. This regular arrangement makes a very smooth gait for you Artificial leg achieved.
