Description
Die Erfindung bezieht sich auf einen Gliederersatz, insbesondere für Beinamputierte, bei denen die natürlichen Glieder und Gelenke durch künstliche ersetzt werden. Derartige künstliche Glieder sind in verschiedenartigen Ausführungen bekannt. The invention relates to limb replacement, in particular for leg amputees in whom the natural limbs and joints are replaced by artificial ones be replaced. Such artificial limbs come in various designs known.
Bei derartigen Konstruktionen ist in der Hauptsache darauf zu achten, daß die Prothesen an Gewicht leicht sind, aber trotzdem eine hohe Festigkeit aufweisen, ferner muß die Bewegung in-den Gelenken elastisch sein und sich nach Möglichkeit derjenigen der natürlichen Gelenke anpassen.With such constructions, the main thing to pay attention to is that that the prostheses are light in weight, but still have high strength, Furthermore, the movement in the joints must be elastic and if possible adapt to that of the natural joints.
Aufgabe der Erfindung ist es nun, derartige Prothesen hinsichtlich ihres Gewichtes und der Elastizität der Gelenke zu verbessern. The object of the invention is now to provide such prostheses with regard to to improve their weight and the elasticity of the joints.
Erfindungsgemäß geschieht dieses dadurch, daß die einzelnen Gliedmaßen aus Distanzrohren gebildet sind, die durch an ihren beiden Enden aufgesteckte Abdeckplatten mit Hilfe von Spanndrähten oder Seilen fest verspannt sind, wobei die Ahdeckplatten je nach Art der Gelenke als Gelenkplatten dienen. Erfindungsgemäß ist bei besagter Ausführung das Kniegelenk einer Beinprothese in Laschen über zwei Drehachsen schwenkbar und durch Gummi- oder Federpolster abgestützt bzw. durch Zugbänder gehalten. Dabei ist der Oberteil des Oberschaftes. also der Teil, in welchem der Gliedstumpf ruht, durch Federn oder Gummieinlagen gegen den Unterteil des Oberschaftes gesondert elastisch abgestützt. According to the invention, this is done in that the individual limbs are formed from spacer tubes, which are attached by cover plates at both ends are tightly braced with the help of tensioning wires or ropes, with the cover plates serve as hinge plates depending on the type of joints. According to the invention is said The knee joint of a leg prosthesis can be swiveled in brackets over two axes of rotation and supported by rubber or spring pads or held by drawstrings. Included is the upper part of the upper body. so the part in which the limb rests, separately elastic against the lower part of the upper shaft by springs or rubber inserts supported.
Im folgenden ist ein Ausführungsbeispiel unter Bezugnahme auf die Erfindung beschrieben. The following is an embodiment with reference to FIG Invention described.
Der Oberschaft einer Beinprothese ist im wesentlichen aus dem Oberteil, das ist die Kappe I, zur Aufnahme des Gliedstumpfes, dem Unterteil, das ist die Verspannung mit den beiden Platten 2 und 3, dem Distanzrohr 4 und den Spanndrähten j gebildet. The upper shaft of a leg prosthesis is essentially made up of the upper part, that is the cap I, for receiving the limb, the lower part, that is the Bracing with the two plates 2 and 3, the spacer tube 4 and the tensioning wires j formed.
Die obere Platte 2 ist entweder mit der Kappe I fest verbunden, wie in Abb. I ersichtlich, oder nach Abb. 3 durch Federn 6 abgestützt. An Stelle der Federn 6 kann sinngemäß auch eine elastische Zwischenlage zwischen der Kappe I und der Platte 2 eingelegt werden. The top plate 2 is either firmly connected to the cap I, such as can be seen in Fig. I, or supported by springs 6 according to Fig. 3. Instead of Springs 6 can analogously also be an elastic intermediate layer between the cap I and the plate 2 are inserted.
Der Unterschaft besteht aus den Platten 7 und 8, dem Distanzrohr g und den Spanndrähten IO. Die obere Platte 7 des Unterschaftes ist vermittels zweier Laschen II um zwei Schwenkachsen I2 und I3 schwenkbar. The lower shaft consists of plates 7 and 8, the spacer tube g and the tension wires IO. The upper plate 7 of the lower shaft is by means of two Lugs II can be pivoted about two pivot axes I2 and I3.
In der Kehlseite des Kniegelenkes zwischen den Platten 3 und 7 ist ein besonders ausgebildetes Gummistück I6 eingesetzt, wogegen sich auf der Kniescheibenseite Gummizugbänder 14 befinden. In the throat side of the knee joint between plates 3 and 7 is a specially designed piece of rubber I6 is used, whereas on the kneecap side Elastic bands 14 are located.
Bei gestreckter Prothese stützt sich die Platte 3 noch auf zwei Gummipolster 15 ab. When the prosthesis is stretched, the plate 3 is still supported on two rubber pads 15 from.
Der angelenkte elastische Fuß I7 entspricht der normalen Ausführung. Ein an diesem angebrachtes Gummipolster ist mit I8 gekennzeichnet (Abb. I). The articulated elastic foot I7 corresponds to the normal design. A rubber pad attached to this is marked with I8 (Fig. I).
Die Wirkungsweise dieser Anordnung mit den beiden Laschen II und dem Gummipolster I6, vereint mit dem Zugband I4, ist wie folgt: Beim Einknicken des Kniegelenkes gemäß Abb. 2 legt sich die Platte 3 in die federnde Mulde des Gummistückes I6, wobei sich die Laschen 1 1 nach vorn verlegen. Beim Strecken des Gelenkes nach erfolgter Beugung legt sich der hintere, abgerundete Teil der Platte 3 gegen den hinteren Wulst des Gummikörpers I6, wodurch die Streckbewegung abgebremst und eine weitaus bessere Standfestigkeit erreicht wird gegenüber sonstigen, bisher bekanntgewordenen Konstruktionen. The operation of this arrangement with the two tabs II and The rubber pad I6, combined with the tension band I4, is as follows: When it is buckled of the knee joint according to Fig. 2, the plate 3 lies in the resilient depression of the rubber piece I6, with the tabs 1 1 moving forward. When stretching the joint after Once the flexion has taken place, the rear, rounded part of the plate 3 lies against the rear bead of the rubber body I6, whereby the stretching movement braked and a far better stability is achieved compared to other, previously known Constructions.
