Abstract
Description
Hintergrund der ErfindungBackground of the invention
(a) Bereich der Erfindung(a) Field of the invention
Die vorliegende Erfindung betrifft ein stoßverringerndes künstliches Knie, welches unter Einsatz von Gelenken mindestens zwei beweglich verbundene Abschnitte hat, welche zusammen mit einem Schwenkbegrenzer und einer pneumatischen Zylinderstruktur dem Knie eine sichere und gleichmäßige Arbeitsweise erlauben, die zur Schonung des Prothesenträgers beiträgt.The The present invention relates to an impact-reducing artificial Knee, which uses at least two movable joints has connected sections, which together with a Schwenkbegrenzer and a pneumatic cylinder structure the knee a safe and uniform operation allow, which contributes to the protection of the prosthesis wearer.
(b) Beschreibung des derzeitigen Standes der Technik(b) Description of the current state of the technique
Der Fortschritt in der Medizintechnik macht es heutzutage möglich, daß durch Einsatz eines künstlichen Kniegelenks zusammen mit einer Beinprothese der Betroffene wieder nahezu natürlich gehen kann.Of the Progress in medical technology makes it possible today through that Use of an artificial Knee joint together with a prosthetic leg of the person concerned again almost natural can go.
Wegen des äußerst komplizierten Aufbaus des menschlichen Knies kann ein konventionelles künstliches Knie die Funktion des natürlichen Knies nicht vollständig nachbilden und erlaubt daher dem Benutzer keinen vollkommen natürlichen Gang. Wenn ein Erwachsener mit seinen natürlichen Knien geht, steht ein Bein senkrecht, um das Körpergewicht zu tragen, während das andere angehoben, nach vorne bewegt und abgesenkt wird bis es den Boden berührt. Bevor es den Boden berührt werden beide Kniegelenke leicht angewinkelt, um die Bodenberührung weicher ablaufen zu lassen und um den nächsten Schritt vorzubereiten. Beim Gang mit einem künstlichen Kniegelenk unterliegt der dem Unterschenkel entsprechende Teil keiner Kontrolle im Hinblick die Stellung des Fußes und dem Winkel mit dem das Knie gebogen wird, wenn der Fuß durch die Kraft des Oberschenkels angehoben und nach vorne bewegt wird. Beim Auftreten der Prothese auf dem Boden wird daher der Hauptteil des Körpergewichts von dem der Ferse entsprechenden Teil aufgenommen. Der dadurch erzeugte Stoß wird an die Wirbelsäule abgegeben und an das Gehirn sowie andere Organe weitergeleitet. Längeres Gehen mit einer derartigen Prothese führt daher zu Unbehaglichkeit, wenn nicht zu Körperschäden.Because of of the extremely complicated Construction of the human knee can be a conventional artificial Knee the function of the natural Knee not completely therefore, it does not simulate and allow the user a completely natural one Corridor. When an adult walks with his natural knees, one gets in Leg perpendicular to the body weight too wear while the other is raised, moved forward and lowered until it is touched the ground. Before it touches the ground Both knee joints are slightly angled to soften the ground contact to expire and to the next Prepare step. When walking with an artificial knee joint is subject the lower leg corresponding part of any control in terms the position of the foot and the angle at which the knee is bent when the foot goes through the force of the thigh is lifted and moved forward. When the prosthesis on the floor is therefore the main part of body weight taken from the heel corresponding part. The generated thereby Shock will delivered to the spine and forwarded to the brain and other organs. Longer walking with such a prosthesis leads therefore uncomfortable, if not to physical injury.
Zusammenfassung der ErfindungSummary of the invention
Hauptziel der Erfindung ist ein künstliches Kniegelenk, das bessere Abfederung und Dämpfung der beim Gehen auftretenden Stöße erlaubt.main goal the invention is an artificial knee joint, the better cushioning and cushioning of the allowed to go while walking.
Zur Erreichung dieses Ziels dient ein stoßverringerndes künstliches Knie, bestehend aus einem oberen Koppelstück mit einem Anschlußkopf zur Befestigung an einem Oberschenkel und einem unteren Verbindungsstück zur Aufnahme eines Pneumatikzylinders. Zwischen beiden befindet sich das eigentliche Kniegelenk mit dem Gelenkstopper und der mittleren Gelenksektion. Die Stoßdämpfung erfolgt im Wesentlichen durch Reibung im Gelenkstopper und die Reaktion des Pneumatikzylinders.to Achieving this goal serves a shock-reducing artificial Knee, consisting of an upper coupling piece with a connection head to Attachment to a thigh and a lower connector for receiving a pneumatic cylinder. Between the two is the actual Knee joint with the joint stopper and the middle joint section. The shock absorption takes place essentially by friction in the joint stopper and the reaction of the pneumatic cylinder.
