Description

KniebereichsteilungsadapterKnee area division adapter

Die vorliegende Erfindung betrifft einen Kniebereichsteilungsadapter für das Gebiet der Beinprothesen, wie sie beispielsweise bekannt sind aus derDE-A-199 53 972.The present invention relates to a knee area division adapter for the field of leg prostheses, as known for example from DE-A-199 53 972.

Grundsätzlich besteht eine derartige Beinprothese aus einem am Oberschenkelstumpf befestigten oder befestigbaren Oberschenkelteil, aus einem daran befestigten Kniegelenk und einem am Kniegelenk angekoppelten Prothesenunterschenkel. Wenn die Beinprothese und insbesondere die zum Einsatz kommenden Kniegelenke schon eine erstaunliche Funktionalität im Hinblick auf einen möglichst physiologischen Bewegungsabauf haben, ergibt sich ein Problem kosmetischer Art. So werden Beinprothesen üblicherweise häufig mit möglichst hautfarbenen Ausstattungen versehen, damit die Beinprothese in ihrem optischen Erscheinungsbild jenem des natürlichen Beines möglichst nahe kommt. Die erwähnten Ausstattungen sind im Falle des Unterschenkels Hart- oder Weichschäume als kosmetische Umkleidung, wohingegen der Kniebereich mit einem Weichschaum umkleidet wird, da das Kniegelenk bei Wahrnehmung seiner Funktion sehr häufig gebeugt wird im Gegensatz zu dem Hartschaum im Bereich des Unterschenkelteils. Die Belastung führt zu einem Ermüden des Weichschaums um das Kniegelenkteil herum. Hieraus ergibt sich die Notwendigkeit, die Umkleidung im Bereich des Kniegelenks häufiger auszuwechseln als jene im Bereich des Unterschenkelteils. Hierfür gab es bislang in der Praxis allerdings keinen Vorschlag, was zur Folge hatte, dass die gesamte Ganzbeinausstattung ersetzt werden musste, obwohl dies an sich nur im Bereich des Kniegelenkes erforderlich gewesen wäre.Basically, such a leg prosthesis consists of a thigh part that is attached or can be attached to the thigh stump, a knee joint attached to it and a prosthetic lower leg coupled to the knee joint. If the leg prosthesis and in particular the knee joints used already have an astonishing functionality with regard to a movement sequence that is as physiological as possible, a problem of a cosmetic nature arises. For example, leg prostheses are usually often provided with fittings that are as skin-colored as possible so that the leg prosthesis is as close as possible to that of the natural leg in its visual appearance. In the case of the lower leg, the fittings mentioned are hard or soft foams as a cosmetic covering, whereas the knee area is covered with a soft foam because the knee joint is very often bent when performing its function, in contrast to the hard foam in the area of the lower leg. The load leads to fatigue of the soft foam around the knee joint part. This results in the need to replace the covering in the area of the knee joint more often than that in the area of the lower leg part. However, there has been no proposal for this in practice to date, which meant that the entire leg equipment had to be replaced, although this would actually only have been necessary in the area of the knee joint.

Vor diesem Hintergrund ist es nun die Aufgabe der vorliegenden Erfindung, einen Lösungsvorschlag dahingehend zu machen, dass tatsächlich nur jene Teile des kosmetischen Überzuges ausgetauscht werden müssen, bei dem aufgrund von Verschleißerscheinungen ein Auswechseln unumgänglich ist, um neben dem kosmetischen Effekt zu erhalten auch noch beispielsweise das Kniegelenk wirksam vor dem Eindringen von Staub und Schmutz schützen zu können.Against this background, it is now the object of the present invention to propose a solution such that only those parts of the cosmetic cover actually have to be replaced where replacement is unavoidable due to signs of wear in order to not only maintain the cosmetic effect but also, for example, to be able to effectively protect the knee joint from the ingress of dust and dirt.

Gelöst wird diese Aufgabe durch einen Kniebereichsteilungsadapter mit dem Merkmal des Anspruchs 1. Vorteilhafte Weiterbildungen ergeben sich aus den Unteransprüchen.This object is achieved by a knee area division adapter with the feature of claim 1. Advantageous further developments emerge from the subclaims.

Demgemäß ist ein Kniebereichsteilungsadapter zur lösbaren Verbindung eines ersten kosmetischen Schaumteils, das über ein Kniegelenk einer Beinprothese schiebbar und über einen Oberschenkelstumpf stülpbar ist, mit einem zweiten kosmetischen Schaumteil, in das ein Unterschenkelteil der Beinprothese einbettbar ist, vorgesehen. Sie weist zwei miteinander lösbar verbindbare plattenförmige Adapterteile auf, wobei ein erstes Adapterteil mit dem ersten kosmetischen Schaumteil und ein zweites Adapterteil mit dem zweiten kosmetischen Schaumteil lösbar verbindbar ist.Accordingly, a knee area division adapter is provided for detachably connecting a first cosmetic foam part, which can be pushed over a knee joint of a leg prosthesis and pulled over a thigh stump, to a second cosmetic foam part, in which a lower leg part of the leg prosthesis can be embedded. It has two plate-shaped adapter parts that can be detachably connected to one another, wherein a first adapter part can be detachably connected to the first cosmetic foam part and a second adapter part can be detachably connected to the second cosmetic foam part.

Das erste Schaumteil oder Umkleidung umgibt also das Kniegelenk und schützt dieses vor dem Eindringen von Schmutz und Staub. Hin zum Oberschenkelstumpf kann ein umlaufender Verstärkungsring vorgesehen sein, der das erste kosmetische Schaumteil stabil am Oberschenkelstumpf hält. Das erste kosmetische Schaumteil wird in aller Regel aus einem hautfarbenen Weichschaum hergestellt sein. Am unteren Ende des ersten Schaumteils ist dieses lösbar mit dem ersten Adapterteil verbunden, beispielsweise durch eine Verklebung, die werksseitig hergestellt wird, oder das Schaumteil ist mit dem AdapterteilThe first foam part or covering surrounds the knee joint and protects it from the ingress of dirt and dust. A reinforcing ring can be provided around the thigh stump, which holds the first cosmetic foam part firmly on the thigh stump. The first cosmetic foam part is usually made of a skin-colored soft foam. At the lower end of the first foam part, this is detachably connected to the first adapter part, for example by means of an adhesive that is produced in the factory, or the foam part is connected to the adapter part.

verklebbar, so dass das erste Schaumteil und das erste Adapterteil ein Set darstellen. Andere Verbindungsmöglichkeiten sind denkbar.glued together so that the first foam part and the first adapter part form a set. Other connection options are conceivable.

Das zweite kosmetische Schaumteil für das Unterschenkelteil wird in aller Regel aus einem hautfarbenen Hart- oder Weichschaum bestehen, das, wenn die Beinprothese von dem Typ ist, dass das Unterschenkelteil über ein Stützrohr hin zu dem Prothesenfuß verfügt, das Stützrohr umgibt. Knieseitig ist dieses zweite kosmetische Schaumteil mit einem zweiten Adapterteil lösbar verbindbar, beispielsweise wiederum durch eine Verklebung, die werksseitig hergestellt wurde, oder aber das Schaumteil ist mit dem Adapterteil verklebbar, so dass beide wiederum ein verkaufsfähiges Set darstellen.The second cosmetic foam part for the lower leg part will generally consist of a skin-colored hard or soft foam that surrounds the support tube if the leg prosthesis is of the type that the lower leg part has a support tube leading to the prosthetic foot. On the knee side, this second cosmetic foam part can be detachably connected to a second adapter part, for example again by means of an adhesive that was produced in the factory, or the foam part can be glued to the adapter part so that both again form a saleable set.

Beide Schaumteile mit ihrem jeweiligen Adapterteil sind nun miteinander lösbar verbindbar. Dies hat den Vorteil, dass bei der Notwendigkeit, das erste kosmetische Schaumteil um das Kniegelenk ersetzen zu müssen, die Verbindung zwischen den beiden Adapterteilen des Kniebereichsteilungsadapters gelöst werden kann und lediglich das erste kosmetische Schaumteil ersetzt zu werden braucht, wonach dann die Verbindung mit dem zweiten Adapterteil an dem zweiten kosmetischen Schaumteil wieder verbunden werden kann. Somit ist das Ziel erreicht, nur die wirklich notwendig zu ersetzenden Teile der kosmetischen Verkleidung auszuwechseln. Hierdurch sind u. a. bedeutsame Kosteneinsparungen möglich.Both foam parts with their respective adapter parts can now be detachably connected to one another. This has the advantage that if the first cosmetic foam part around the knee joint needs to be replaced, the connection between the two adapter parts of the knee area dividing adapter can be released and only the first cosmetic foam part needs to be replaced, after which the connection with the second adapter part on the second cosmetic foam part can be reconnected. This means that the goal of only replacing the parts of the cosmetic cover that really need to be replaced is achieved. This makes significant cost savings possible, among other things.

Die lösbare Verbindung zwischen den beiden Adapterteilen wird gemäß einer bevorzugten Ausführungsform realisiert durch eine Verrastung. Diese kann in besonders bevorzugter Ausführungsform durch Ösen in dem einen Adapterteil und durch darin einrastbare Haltelaschen auf dem anderen Adapterteil realisiert sein. Mit einer Art Schnappverbindung können beide Teile lösbar miteinander verbunden werden, wobei die Haltelaschen dann aufgrund ihrer Elastizität nachThe detachable connection between the two adapter parts is realized according to a preferred embodiment by a latching mechanism. In a particularly preferred embodiment, this can be realized by eyelets in one adapter part and by retaining tabs that can be latched into them on the other adapter part. Both parts can be detachably connected to one another with a type of snap connection, whereby the retaining tabs can then be pushed back due to their elasticity.

Durchdringung der Ösen nach außen federn und es mit einem Vorsprung verhindern, dass beide Adapterteile ohne zusätzliche Maßnahmen wie Zusammendrücken der Haltelaschen durch die Ösen gezogen werden können.Penetration of the eyelets springs outwards and prevents with a projection that both adapter parts can be pulled through the eyelets without additional measures such as pressing the retaining tabs together.

Die Erfindung wird anhand der Zeichnungsfiguren näher erläutert.

Nachfolgend sind gleiche Teile mit denselben Bezugszeichen versehen.In the following, identical parts are provided with the same reference symbols.

Über den Oberschenkelstumpf 4 ist das erste kosmetische Schaumteil 1 gestülpt und wird mit Hilfe eines umlaufenden Verstärkungsringes 13 in Lage gehalten. Das erste kosmetische Schaumteil 1 ist vorliegend grau schraffiert dargestellt, um insofern auch eine optische Unterscheidung zum zweiten kosmetischen Schaumteil 5 zu bewirken. Unterschenkelseitig ist das erste kosmetische Schaumteil 1 abgeschlossen durch ein erstes Adapterteil 7. Das Schaumteil 1 beherbergt in seinem Inneren ein Kniegelenk 2 der Beinprothese 3.The first cosmetic foam part 1 is placed over the thigh stump 4 and is held in position with the help of a surrounding reinforcing ring 13. The first cosmetic foam part 1 is shown here with gray hatching in order to visually distinguish it from the second cosmetic foam part 5. On the lower leg side, the first cosmetic foam part 1 is closed off by a first adapter part 7. The foam part 1 houses a knee joint 2 of the leg prosthesis 3 inside.

Teil der Beinprothese 3 ist auch das Unterschenkelteil 6, welches vorliegend über ein Stützrohr 9 verfügt.Part of the leg prosthesis 3 is also the lower leg part 6, which in this case has a support tube 9.

Das schon erwähnte zweite kosmetische Schaumteil 5 umschließt das Unterschenkelteil 6. Kniewärts ist das zweite Schaumteil 5 abgeschlossen durch ein lösbar mit ihm verbundenes zweites Adapterteil 8. Die Verbindung des zweiten Adapterteils 8 mit dem Stützrohr 9 erfolgt vorliegend lösbar durch den Rohradapter 10.The previously mentioned second cosmetic foam part 5 encloses the lower leg part 6. Towards the knee, the second foam part 5 is closed by a second adapter part 8 that is detachably connected to it. The connection of the second adapter part 8 to the support tube 9 is detachably made in this case by the tube adapter 10.

Beide Adapterteile 7 und 8 sind ebenfalls miteinander lösbar verbunden. Hierbei sind im Adapterteil 7 Ösen 11 vorgesehen. Mit der Herstellung der lösbaren Verbindung zwischen den Adapterteilen 7 und 8 werden am Adapterteil 8 angeformte Haltelaschen 12 durch die Ösen 11 im Adapterteil 7 geschoben, und zwar so lange, bis diese mit ihren Köpfen in den Ösen verrasten. Durch Zusammendrücken der gegenüberliegenden Haltelaschen 12 in den Ösen 11 kann die Verbindung zwischen den Adapterteilen 7 und 8 wieder aufgehoben werden und beispielsweise das erste kosmetische Schaumteil 1 ersetzt werden, wohingegen das zweite kosmetische Schaumteil 5 weiter verwendet werden kann.Both adapter parts 7 and 8 are also detachably connected to one another. Eyelets 11 are provided in the adapter part 7. When the detachable connection between the adapter parts 7 and 8 is created, retaining tabs 12 formed on the adapter part 8 are pushed through the eyelets 11 in the adapter part 7 until their heads lock into the eyelets. By pressing the opposing retaining tabs 12 together in the eyelets 11, the connection between the adapter parts 7 and 8 can be removed again and, for example, the first cosmetic foam part 1 can be replaced, whereas the second cosmetic foam part 5 can continue to be used.

Die Adapterteile 7 und 8 können beispielsweise werksmäßig mit den Schaumteilen 1 bzw. 5 verklebt sein, oder aber als Set mit diesen ausgeliefert werden, woraufhin dann der Patient selbst die Verbindung herstellen kann.The adapter parts 7 and 8 can, for example, be factory-glued to the foam parts 1 and 5 respectively, or can be delivered as a set with them, after which the patient can then make the connection himself.
