Description

Sperrvorrichtung für künstliche Kniegelenke. Die Erfindung betrifft eine Sperrvorrichtung für künstliche Kniegelenke und besteht darin, daß auf die Dutte des nach bekannter Weise in Seitenschienen gehaltenen, zweckmäßig konischen Gelenkbolzens ein gegen einen elastischen Anschlag des Oberschenkels in der Strecklage des Beines auftreffendes und auswechselbares Rohrstück aufgeschoben ist, dessen unteres Ende im Unterschenkel festsitzt, und dessen Lagerkopf nach der Kniekehle hin einen rastartigen Ausschnitt aufweist; in den letzteren greift ein Sperrzahn einer, über einen auswechselbaren Bolzen oberhalb der Kniegelenkachse geschobenen und mit der Hand beweglichen Sperrklinke ein, welche in diesem Zustande das künstliche Bein in der Streckrichtung hält.Locking device for artificial knee joints. The invention relates to a locking device for artificial knee joints and consists in that on the Dutte of the appropriately conical, held in side rails in a known manner Hinge pin one against an elastic stop of the thigh in the extended position of the leg impacting and replaceable piece of pipe is pushed lower end is stuck in the lower leg, and its bearing head to the hollow of the knee has a ratchet-like cutout; a ratchet engages in the latter one, pushed over a replaceable bolt above the knee joint axis and a pawl which can be moved by hand, which in this state is the artificial Holds the leg in the direction of extension.

Auf der Zeichnung ist der Erfindungsgegenstand dargestellt, und zwar zeigt Abb. Z einen Längsschnitt, Abb. a einen Querschnitt.The subject of the invention is shown in the drawing, namely Fig. Z shows a longitudinal section, Fig. a shows a cross section.

Von den Seitenschienen a' und ä ' gehalten, durchdringt die konische Knieachse b das Kunstbein in seiner ganzen Breite. In der Mitte der Knieachse b ist der mit einem Ausschnitt c versehene Lagerkopf des Anschlagrohres d auswechselbar aufgesteckt.Held by the side rails a ' and ä' , the conical knee axis b penetrates the artificial leg in its entire width. In the middle of the knee axis b, the bearing head of the stop tube d, which is provided with a cutout c, is plugged in an exchangeable manner.

Der untere Teil desselben ruht fest im Material des Unterschenkels und trifft auf einen Anschlag e des Oberschenkels auf, der elastisch ist. Die Achse f des Sperrzahnes g ist oberhalb der Kniegelenkachse b auswechselbar angeordnet, so daß der Sperrzahn g durch Drehung des Hebels h mit der Hand in den Ausschnitt c zwecks Feststellung beliebig aus- und eingeschaltet werden kann.The lower part of the same rests firmly in the material of the lower leg and meets a stop e of the thigh, which is elastic. The axis f of the ratchet tooth g is arranged exchangeably above the knee joint axis b, so that the ratchet tooth g by turning the lever h by hand in the cutout c can be switched on and off at will for the purpose of detection.
