Definitions
- the invention relates to a lightweight prosthesis for the purely optical replacement of missing extremities with a molded body simulating the missing extremity, and to a receptacle for connecting the prosthesis to the stump of the missing extremity.
- the invention serves only as an optical limb replacement for the temporary or permanent care of all types of amputations of the upper and lower extremities.
- the present prosthesis is not intended to achieve stability or functionality. This means that the prosthesis should not be used for walking or grasping, but should only be used as an optical replacement that reproduces the missing extremity as faithfully as possible. Especially elderly patients after amputations not to deal in the area, with prostheses, which allow a walking or 'grasp.
- EP 0 151 834 AI describes a leg prosthesis, in particular for use in the bathing area, which consists of a relatively firm shell and is provided on the inside with several inflatable air chambers. The area of the foot has a relatively large contact surface, which comprises a stiff sole.
- the air chamber between the sole and the stump of the missing extremity assumes a certain stability, so that an occurrence on the artificial extremity is possible at least to a certain extent. If the prosthesis is not used, it can be folded up for storage or transportation. In order to achieve the necessary stability, the prosthesis becomes ever wider towards the foot, which does not correspond to the natural shape of the leg, so that such a prosthesis cannot serve as a visual replacement.
- GB 2 064 331 A describes an inflatable prosthesis which is intended in particular for use immediately after amputation or after very long use of conventional prostheses. In order to enable the stump of the missing extremity to be assessed even when the prosthesis is attached, the prosthesis is preferably made of transparent material.
- the prosthesis is made of a relatively thick material and has a two-layer structure, with a plurality of air chambers being formed between the two layers.
- the prosthesis tapers downwards and ends in the form of a knob-like element.
- This prosthesis is also unsuitable for an optical replacement of the missing limbs.
- US 3 889 301 A shows a leg prosthesis in which the receptacle for the stump of the missing extremity is provided with an inflatable layer.
- Such prostheses are used for therapeutic purposes by freshly amputated patients.
- the lower area of the prosthesis includes a stem and a foot replica, which does not match the shape of a natural leg.
- the US 4790855 A relates to an elastic support element for fastening the prosthetic legs after amputations of the leg above the knee.
- the element is essentially made of a part made of flexible, elastic material, which is connected to the stump and waist, preferably via Velcro fasteners.
- the circumference of the support element can be adapted to the respective circumference of the stump.
- No information is given on the nature of the prosthesis itself or the receptacle for connecting the prosthesis to the stump.
- EP 0806193 AI shows a leg prosthesis which contains a special, extremely elastic sleeve as a receptacle for connecting the prosthesis to the stump.
- the sleeve is pulled over the stump as well as over the proximal end of the prosthesis, whereby the prosthesis is held securely on the stump.
- the aim of the present invention is therefore to create a prosthesis mentioned at the outset which can be connected as simply as possible to the stump of the missing extremity and which is as light and simple as possible.
- the prosthesis does not have to or gripping function, but only serves as an optical replacement for the missing extremity.
- the prosthesis according to the invention should be able to be used for the largest possible area of extremities of different sizes, so that no expensive and complex custom-made products are required.
- the cost of manufacturing the prosthesis should be as low as possible for the widest possible use.
- the object of the invention is achieved in that the molded body consists of light plastic material and that the extent of the receptacle for connecting the prosthesis to the stump can be changed in a manner known per se.
- a prosthesis in which the molded body consists of light plastic material, is relatively easy and inexpensive to manufacture and has a low weight. Due to the changeable extent of the receptacle for connecting the prosthesis to the stump of the missing extremity, the prosthesis can be used for different dimensions of the stump.
- the prosthesis described can thus also be used as an optical replacement for the missing limb by older patients who are no longer able to wear a functional prosthesis.
- the molded body can, for example, be hollow or made of light material, for example styrofoam, preferably with a covering made of resistant plastic.
- the variability of the circumference of the receptacle for connecting the prosthesis to the stump can be formed by the receptacle being made of elastic material at least in a partial area of the circumference. This represents a particularly simple way of realizing a variable scope.
- the receptacle includes quick-release fasteners, for example Velcro fasteners, for fixing the stump.
- quick-release fasteners for example Velcro fasteners
- the length of the receptacle can also be changed, so that the prosthesis can also be used for patients of different sizes with extremities of different lengths.
- the variability of the length of the receptacle can be formed in that the receptacle consists of elastic material over at least a partial area of its length, and that the elastic material forms at least one fold in this partial area in order to achieve a change in the length of the receptacle.
- the receptacle can be designed to overlap in a partial area by forming two folds, the overlap being adapted to the length of the stump and the length of the extremity.
- the at least one fold is advantageously fixed by quick fasteners, in particular Velcro fasteners.
- the prosthesis can thus be quickly and easily fixed in the desired length.
- the molded body of the prosthesis for the optical replacement of missing limbs can also contain one joint or several joints for simulating the joint or the joints of the missing extremity.
- the functionality of this joint should only be limited to the absolute necessity. This means that, for example in the case of a leg prosthesis, a certain flexion of the knee joint should be made possible, whereas, on the other hand, functionality of the ankle is usually not necessary.
- the molded body of the prosthesis advantageously consists of elastic, air-impermeable plastic and has at least one valve for inflating the molded body.
- an inflatable prosthesis can be realized, which is particularly simple and inexpensive to manufacture. Due to the receptacle designed according to the invention, it is not necessary to produce a custom-made prosthesis for each patient, which would increase the manufacturing costs.
- the molded body can have a plurality of interconnected air chambers. Due to the special arrangement of the air chambers, the natural shape of the missing extremity can be reproduced well. Reinforcement layers made of plastic can be arranged in partial areas on the inside of the molded body. These can be used to form the joints or to reinforce stressed areas, for example the heel area or the foot the shoe is streaked serve.
- the surface of the molded body is expediently reproduced by the coloring and surface structure of the skin of the missing extremity.
- the prosthesis has fastening straps by means of which it can be connected to the patient's body.
- FIG. 1 schematically shows a side view of a leg prosthesis according to the present invention
- 2 shows a partial area of the receptacle of the prosthesis with an elastic partial area
- 3 shows the inclusion of a prosthesis with quick-release fasteners
- 4 shows an embodiment of the receptacle of the prosthesis with which the length of the receptacle can be changed
- 5 shows a sectional view of the view according to FIG. 4 along the section line VV
- FIG. 6 shows a variant of a leg prosthesis with an inflatable molded body.
- FIG. 1 schematically shows a prosthesis for the optical replacement of missing limbs in the illustrated example of a missing leg with a molded body 1 simulating the missing extremity, and a receptacle 2 for connecting the prosthesis to the stump 3 of the missing extremity.
- the molded body 1 is made of plastic and has no functional purposes. This means that with the help of the present prosthesis, no walking or gripping function has to be performed.
- the scope of the receptacle 2 for connecting the prosthesis to the stump 3 can be changed, so that the prosthesis can be connected to stumps of different sizes of missing extremities.
- FIG. 2 shows an embodiment variant of a changeability of the circumference of the receptacle 2, which consists of a partial area 4 of the receptacle 2 made of elastic material.
- the scope of the receptacle 2 can thus be adapted to a certain extent to stumps 3 of missing extremities of different sizes.
- FIG. 3 shows A further variant of a change in the circumference of the receptacle 2 in FIG. 3, where the circumference of the receptacle 2 can be fixed with the aid of quick-release fasteners 6, for example Velcro fasteners.
- the receptacle 2 is placed in two folds in the area 5, and the fold is fixed with the aid of the quick fasteners 6.
- FIG. 6 shows a sectional view of an embodiment variant of the prosthesis, wherein the molded body 1 consists of elastic, air-impermeable plastic material 9 and has at least one valve 10 for inflating the molded body 1. This creates an inflatable prosthesis that is particularly simple and inexpensive to manufacture.
- Reinforcement layers 11 made of plastic can be arranged on the inside of the molded body 1 at sensitive points.
- fastening straps 12 can be arranged for further fastening of the prosthesis to the patient's body.

Abstract
Description
Leichtprothese easy prosthesis
Die Erfindung betrifft eine Leichtprothese zum rein optischen Ersetzen fehlender Extremitäten mit einem die fehlende Extremitat nachbildenden Formkörper, und einer Aufnahme zum Verbinden der Prothese mit dem Stumpf der fehlenden Extremitat. Die Erfindung dient nur als optischer Gliedmaßenersatz zur temporären oder permanenten Versorgung von allen Arten von Amputationen der oberen und unteren Extremitat. Eine Stabilität oder Funktionalität soll mit Hilfe der vorliegenden Prothese nicht erzielt werden. Das bedeutet, die Prothese soll nicht zum Gehen oder Greifen dienen, sondern nur als optischer Ersatz einsetzbar sein, der die fehlende Extremitat möglichst naturgetreu nachbildet. Insbesondere ältere Patienten sind nach Amputationen nicht in der Lage, mit Prothesen, welche ein Gehen oder 'Greifen zulassen, umzugehen. Die Gründe dafür liegen einerseits in der schlechteren körperlichen Verfassung älterer Patienten und andererseits in einer schlechteren Wundheilung, welche die Anwendung normaler Prothesen nicht zulassen. Nichtsdestotrotz stellen die fehlenden Extremitäten bei älteren Patienten auch ein psychisches Problem dar, weshalb ein Bedarf an kosmetischen Prothesen besteht. Neben einer Reihe von Prothesen, welche auch Geh- und Greiffunktionen erfüllen, existieren auch Prothesen für temporäre Verwendung. Beispielsweise beschreibt die EP 0 151 834 AI eine Beinprothese, insbesondere zur Verwendung im Badebereich, welche aus einer relativ festen Hülle besteht und innen mit mehreren aufblasbaren Luftkammern versehen ist. Der Bereich des Fußes weist eine relativ große Auflagefläche auf, welche eine steife Sohle umfasst. Die Luftkammer zwischen der Sohle und dem Stumpf der fehlenden Extremitat übernimmt eine gewisse Stabilität, so dass ein Auftreten auf die künstliche Extremitat zumindest bis zu einem gewissen Grad möglich ist. Wird die Prothese nicht verwendet, kann sie zur Lagerung oder für einen Transport zusammengelegt werden. Um die notwendige Stabilität zu erzielen, wird die Prothese in Richtung Fuß immer breiter, was der natürlichen Form des Beines nicht entspricht, so dass eine derartige Prothese nicht als optischer Ersatz dienen kann. Die GB 2 064 331 A beschreibt eine aufblasbare Prothese, die insbesondere für einen Einsatz unmittelbar nach der Amputation oder nach sehr langem Gebrauch konventioneller Prothesen gedacht ist. Um die Begutachtung des Stumpfes der fehlenden Extremitat auch bei befestigter Prothese zu ermöglichen, ist die Prothese vorzugsweise aus transparentem Material hergestellt. Um eine gewisse Stabilität zu erzielen, ist die Prothese aus relativ dickem Material hergestellt und zweischichtig aufgebaut, wobei zwischen den beiden Schichten mehrere Luftkammern gebildet werden. Die Prothese ist nach unten verjüngend ausgebildet und endet in Form eines knaufähnlichen Elements. Auch diese Prothese ist nicht für einen optischen Ersatz der fehlenden Gliedmaße geeignet. Schließlich zeigt die US 3 889 301 A eine Beinprothese, bei der die Aufnahme für den Stumpf der fehlenden Extremitat mit einer aufblasbaren Schicht versehen ist. Derartige Prothesen werden zu therapeutischen Zwecken frisch Amputierter eingesetzt. Der untere Bereich der Prothese umfasst einen Stiel und eine Fußnachbildung, welche der Form eines natürlichen Beines nicht entspricht . Die US 4790855 A betrifft ein elastisches Stützelement zur Befestigung der Beinprothesen nach Amputationen des Beines über dem Knie. Das Element ist im Wesentlichen aus einem Teil aus flexiblem, elastischen Material hergestellt, welches am Stumpf sowie in der Taille, vorzugsweise, über Klettverschlüsse verbunden wird. Dadurch kann der Umfang des Stützelements an den jeweiligen Umfang des Stumpfes angepasst werden. Über die Beschaffenheit der Prothese selbst sowie der Aufnahme zum Verbinden der Prothese mit dem Stumpf werden keine Angaben gemacht. Die EP 0806193 AI zeigt eine Beinprothese, welche eine spezielle extrem elastische Hülse als Aufnahme zum Verbinden der Prothese mit dem Stumpf beinhaltet. Die Hülse wird dabei sowohl über den Stumpf als auch über das proximale Ende der Prothese gezogen, wodurch ein sicherer Halt der Prothese am Stumpf erzielt wird. Die Handhabbarkeit einer derartigen Hülse ist jedoch relativ aufwendig. Ziel der vorliegenden Erfindung ist daher die Schaffung einer eingangs erwähnten Prothese, welche möglichst einfach mit dem Stumpf der fehlenden Extremitat verbindbar ist und möglichst leicht und einfach aufgebaut ist. Die Prothese muss keine Geh- oder Greiffunktion erfüllen, sondern dient lediglich als optischer Ersatz der fehlenden Extremitat. Weiters soll die erfindungsgemäße Prothese für einen möglichst großen Bereich verschieden großer Extremitäten einsetzbar sein, so dass keine teuren und aufwendigen Sonderanfertigungen erforderlich sind. Die Kosten der Herstellung der Prothese sollen für eine möglichst breite Anwendung möglichst niedrig sein. Gelöst wird die erfindungsgemäße Aufgabe dadurch, dass der Formkörper aus leichtem Kunststoffmaterial besteht, und dass der Umfang der Aufnahme zum Verbinden der Prothese mit dem Stumpf in an sich bekannter Weise veränderbar ist. Eine derartige Prothese, bei der der Formkörper aus leichtem Kunststoffmaterial besteht, ist relativ leicht und kostengünstig herstellbar und weist ein geringes Gewicht auf. Durch den veränderbaren Umfang der Aufnahme zum Verbinden der Prothese mit dem Stumpf der fehlenden Extremitat kann die Prothese für verschiedene Dimensionen des Stumpfes eingesetzt werden. Die beschriebene Prothese kann somit als optischer Ersatz der fehlenden Gliedmaße auch von älteren Patienten verwendet werden, welche nicht mehr in der Lage sind, eine funktioneile Prothese zu tragen. Somit kommen beispielsweise auch Diabetiker, die häufig in hohem Alter aufgrund der Spätfolgen ihrer Krankheit Amputationen der oberen und unteren Extremitäten erleiden, derartige Prothesen tragen. Beispielsweise können Beinamputierte eine derartige Prothese im Rollstuhl sitzend tragen, so dass das Fehlen der Extremitäten nicht oder nicht sofort offensichtlich wird. Der Formkörper kann beispielsweise hohl ausgeführt sein oder aus leichtem Material, beispielsweise Styropor, vorzugsweise mit einer Umhüllung aus widerstandsfähigem Kunststoff, bestehen. Die Veränderbarkeit des Umfanges der Aufnahme zum Verbinden der Prothese mit dem Stumpf kann dadurch .gebildet sein, dass die Aufnahme zumindest in einem Teilbereich des Umfanges aus elastischem Material besteht. Dies stellt eine besonders einfach zu realisierende Möglichkeit der Erzielung eines veränderbaren Umfanges dar. Gemäß einem weiteren Merkmal der Erfindung ist vorgesehen, dass die Aufnahme Schnellverschlüsse, beispielsweise Klettverschlüsse, zur Fixierung des Stumpfes beinhaltet. Somit kann ein Anlegen der Prothese besonders rasch und einfach von älteren Patienten vorgenommen werden. Vorteilhafterweise ist auch die Länge der Aufnahme veränderbar, so dass die Prothese auch für verschieden große Patienten mit verschieden langen Extremitäten eingesetzt werden kann. Die Veränderbarkeit der Länge der Aufnahme kann dadurch gebildet werden, dass die Aufnahme zumindest auf einem Teilbereich seiner Länge aus elastischem Material besteht, und dass das elastische Material in diesem Teilbereich zur Erzielung einer Längenveränderung der Aufnahme zumindest eine Falte ausbildet. Insbesondere kann die Aufnahme in einem Teilbereich durch Bildung zweier Falten überlappend ausgebildet sein, wobei die Überlappung an die Länge des Stumpfes und die Länge der Extremitat angepasst wird. Vorteilhafterweise wird die zumindest eine Falte durch Schnellverschlüsse, insbesondere Klettverschlüsse, fixiert. Somit kann die Prothese rasch und einfach in der gewünschten Länge fixiert werden. Der Formkörper der Prothese zum optischen Ersetzen fehlender Extremitäten kann auch ein Gelenk oder mehrere Gelenke zur Nachbildung des Gelenks oder der Gelenke der fehlenden Extremitat beinhalten. Die Funktionalität dieses Gelenks soll jedoch nur auf die absolute Notwendigkeit beschränkt sein. Dies bedeutet, dass beispielsweise bei einer Beinprothese eine gewisse Beugung des Kniegelenks ermöglicht werden soll, wo hingegen eine Funktionalität des Fußgelenkes meist nicht erforderlich ist. Vorteilhafterweise besteht der Formkörper der Prothese aus elastischem, luftundurchlässigem Kunststoff und weist zumindest ein Ventil zum Aufblasen des Formkörpers auf. Somit kann eine aufblasbare Prothese realisiert werden, welche besonders einfach und kostengünstig herstellbar ist. Durch die erfindungsgemäß ausgebildete Aufnahme ist es nicht erforderlich, für jeden Patienten eine maßgefertigte Prothese herzustellen, was die Herstellungskosten steigern würde. Der Formkörper kann mehrere miteinander verbundene Luftkammern aufweisen. Durch die spezielle Anordnung der Luftkammern kann die natürliche Form der fehlenden Extremitat gut nachgebildet werden. In Teilbereichen an der Innenseite des Formkörpers können Verstärkungsschichten aus Kunststoff angeordnet sein. Diese können zur Bildung der Gelenke oder zur Verstärkung beanspruchter Bereiche, beispielsweise des Fersenbereichs, des Fußes, über den der Schuh gestreift wird, dienen. Zweckmäßigerweise ist die Oberfläche des Formkörpers durch Farbgebung und Oberflächenstruktur der Haut der fehlenden Extremitat nachgebildet. Im Falle besonders hoher Amputationen mit beispielsweise Beckenteilresektionen ist es von Vorteil, dass die Prothese Befestigungsbänder aufweist, über welche diese mit dem Körper des Patienten verbunden werden kann. Die vorliegende Erfindung wird anhand der beigefügten Zeichnungen, welche schematisch Ausführungsbeispiele der Erfindung zeigen, näher erläutert. Dabei zeigen: Fig. 1 schematisch eine Seitenansicht einer Beinprothese gemäß der vorliegenden Erfindung; Fig. 2 einen Teilbereich der Aufnahme der Prothese mit einem elastischen Teilbereich; Fig. 3 die Aufnahme einer Prothese mit Schnellverschlüssen; Fig. 4 eine Ausführungsform der Aufnahme der Prothese, mit der die Länge der Aufnahme veränderbar ist; Fig. 5 ein Schnittbild der Ansicht gemäß Fig. 4 entlang der Schnittlinie V-V; und Fig. 6 eine Variante einer Beinprothese mit einem aufblasbaren Formkörper. Fig. 1 zeigt schematisch eine Prothese zum optischen Ersetzen fehlender Extremitäten im dargestellten Beispiel eines fehlenden Beines mit einem die fehlende Extremitat nachbildenden Formkörper 1, und einer Aufnahme 2 zum Verbinden der Prothese mit dem Stumpf 3 der fehlenden Extremitat. Erfindungsgemäß besteht der Formkörper 1 aus Kunststoff und erfüllt keine funktionellen Zwecke. Das bedeutet, dass mit Hilfe der vorliegenden Prothese keine Geh- oder Greiffunktion erfüllt werden muss. Weiters ist der Umfang der Aufnahme 2 zum Verbinden der Prothese mit dem Stumpf 3 veränderbar, so dass die Prothese an verschieden große Stümpfe fehlender Extremitäten angeschlossen werden kann. Fig. 2 zeigt eine Ausführungsvariante einer Veränderbarkeit des Umfanges der Aufnahme 2, welche durch einen Teilbereich 4 der Aufnahme 2 aus elastischem Material besteht. Somit kann der Umfang der Aufnahme 2 in einem gewissen Rahmen an verschieden große Stümpfe 3 fehlender Extremitäten angepasst werden. Eine weitere Variante einer Veränderbarkeit des Umfanges der Aufnahme 2 ist in Fig. 3 dargestellt, wo mit Hilfe von Schnellverschlüssen 6, beispielsweise Klettverschlüssen, der Umfang der Aufnahme 2 fixiert werden kann. Zu diesem Zweck wird beispielsweise die Aufnahme 2 in zwei Falten im Bereich 5 gelegt, und die Falte mit Hilfe der Schnellverschlüsse 6 fixiert. Auf diese Weise kann eine rasche und einfache Verbindung der Prothese mit dem Stumpf 3 der fehlenden Extremitat auch von älteren Patienten erzielt werden. Die Fig. 4 und 5 zeigen eine Ausführungsvariante, nach der die Aufnahme 2 auch in der Länge veränderbar ist. Dies wird dadurch erzielt, dass zumindest auf einem Teilbereich der Länge der Aufnahme diese aus elastischem Material besteht und zumindest eine Falte 7 bildet, welche wiederum durch Schnellverschlüsse 8, insbesondere Klettverschlüsse, fixiert wird. Schließlich zeigt Fig. 6 ein Schnittbild einer Ausführungsvariante der Prothese, wobei der Formkörper 1 aus elastischem, luftundurchlässigem Kunststoffmaterial 9 besteht und zumindest ein Ventil 10 zum Aufblasen des Formkörpers 1 aufweist. Somit wird eine aufblasbare Prothese geschaffen, welche besonders einfach und kostengünstig herstellbar ist. An empfindlichen Stellen können Verstärkungsschichten 11 aus Kunststoff an der Innenseite des Formkörpers 1 angeordnet werden. Zusätzlich können für eine weitere Befestigung der Prothese am Körper des Patienten Befestigungsbänder 12 angeordnet sein. Obgleich die Zeichnungen durchwegs auf Beinprothesen abgerichtet sind, können genauso Armprothesen gemäß der vorliegenden Erfindung hergestellt werden. The invention relates to a lightweight prosthesis for the purely optical replacement of missing extremities with a molded body simulating the missing extremity, and to a receptacle for connecting the prosthesis to the stump of the missing extremity. The invention serves only as an optical limb replacement for the temporary or permanent care of all types of amputations of the upper and lower extremities. The present prosthesis is not intended to achieve stability or functionality. This means that the prosthesis should not be used for walking or grasping, but should only be used as an optical replacement that reproduces the missing extremity as faithfully as possible. Especially elderly patients after amputations not to deal in the area, with prostheses, which allow a walking or 'grasp. The reasons for this lie on the one hand in the poorer physical condition of older patients and on the other hand in poorer wound healing, which do not allow the use of normal prostheses. Nevertheless, the missing limbs are also a psychological problem in older patients, which is why there is a need for cosmetic prostheses. In addition to a number of prostheses, which also perform walking and gripping functions, there are also prostheses for temporary use. For example, EP 0 151 834 AI describes a leg prosthesis, in particular for use in the bathing area, which consists of a relatively firm shell and is provided on the inside with several inflatable air chambers. The area of the foot has a relatively large contact surface, which comprises a stiff sole. The air chamber between the sole and the stump of the missing extremity assumes a certain stability, so that an occurrence on the artificial extremity is possible at least to a certain extent. If the prosthesis is not used, it can be folded up for storage or transportation. In order to achieve the necessary stability, the prosthesis becomes ever wider towards the foot, which does not correspond to the natural shape of the leg, so that such a prosthesis cannot serve as a visual replacement. GB 2 064 331 A describes an inflatable prosthesis which is intended in particular for use immediately after amputation or after very long use of conventional prostheses. In order to enable the stump of the missing extremity to be assessed even when the prosthesis is attached, the prosthesis is preferably made of transparent material. In order to achieve a certain stability, the prosthesis is made of a relatively thick material and has a two-layer structure, with a plurality of air chambers being formed between the two layers. The prosthesis tapers downwards and ends in the form of a knob-like element. This prosthesis is also unsuitable for an optical replacement of the missing limbs. Finally, US 3 889 301 A shows a leg prosthesis in which the receptacle for the stump of the missing extremity is provided with an inflatable layer. Such prostheses are used for therapeutic purposes by freshly amputated patients. The lower area of the prosthesis includes a stem and a foot replica, which does not match the shape of a natural leg. The US 4790855 A relates to an elastic support element for fastening the prosthetic legs after amputations of the leg above the knee. The element is essentially made of a part made of flexible, elastic material, which is connected to the stump and waist, preferably via Velcro fasteners. As a result, the circumference of the support element can be adapted to the respective circumference of the stump. No information is given on the nature of the prosthesis itself or the receptacle for connecting the prosthesis to the stump. EP 0806193 AI shows a leg prosthesis which contains a special, extremely elastic sleeve as a receptacle for connecting the prosthesis to the stump. The sleeve is pulled over the stump as well as over the proximal end of the prosthesis, whereby the prosthesis is held securely on the stump. However, the handling of such a sleeve is relatively complex. The aim of the present invention is therefore to create a prosthesis mentioned at the outset which can be connected as simply as possible to the stump of the missing extremity and which is as light and simple as possible. The prosthesis does not have to or gripping function, but only serves as an optical replacement for the missing extremity. Furthermore, the prosthesis according to the invention should be able to be used for the largest possible area of extremities of different sizes, so that no expensive and complex custom-made products are required. The cost of manufacturing the prosthesis should be as low as possible for the widest possible use. The object of the invention is achieved in that the molded body consists of light plastic material and that the extent of the receptacle for connecting the prosthesis to the stump can be changed in a manner known per se. Such a prosthesis, in which the molded body consists of light plastic material, is relatively easy and inexpensive to manufacture and has a low weight. Due to the changeable extent of the receptacle for connecting the prosthesis to the stump of the missing extremity, the prosthesis can be used for different dimensions of the stump. The prosthesis described can thus also be used as an optical replacement for the missing limb by older patients who are no longer able to wear a functional prosthesis. Thus, for example, diabetics, who often experience amputations of the upper and lower extremities due to the late consequences of their illness, also wear such prostheses. For example, leg amputees can wear such a prosthesis while sitting in a wheelchair, so that the absence of the extremities is not or not immediately apparent. The molded body can, for example, be hollow or made of light material, for example styrofoam, preferably with a covering made of resistant plastic. The variability of the circumference of the receptacle for connecting the prosthesis to the stump can be formed by the receptacle being made of elastic material at least in a partial area of the circumference. This represents a particularly simple way of realizing a variable scope. According to a further feature of the invention, it is provided that the receptacle includes quick-release fasteners, for example Velcro fasteners, for fixing the stump. This means that the prosthesis can be put on particularly quickly and easily by older patients. Advantageously, the length of the receptacle can also be changed, so that the prosthesis can also be used for patients of different sizes with extremities of different lengths. The variability of the length of the receptacle can be formed in that the receptacle consists of elastic material over at least a partial area of its length, and that the elastic material forms at least one fold in this partial area in order to achieve a change in the length of the receptacle. In particular, the receptacle can be designed to overlap in a partial area by forming two folds, the overlap being adapted to the length of the stump and the length of the extremity. The at least one fold is advantageously fixed by quick fasteners, in particular Velcro fasteners. The prosthesis can thus be quickly and easily fixed in the desired length. The molded body of the prosthesis for the optical replacement of missing limbs can also contain one joint or several joints for simulating the joint or the joints of the missing extremity. However, the functionality of this joint should only be limited to the absolute necessity. This means that, for example in the case of a leg prosthesis, a certain flexion of the knee joint should be made possible, whereas, on the other hand, functionality of the ankle is usually not necessary. The molded body of the prosthesis advantageously consists of elastic, air-impermeable plastic and has at least one valve for inflating the molded body. Thus, an inflatable prosthesis can be realized, which is particularly simple and inexpensive to manufacture. Due to the receptacle designed according to the invention, it is not necessary to produce a custom-made prosthesis for each patient, which would increase the manufacturing costs. The molded body can have a plurality of interconnected air chambers. Due to the special arrangement of the air chambers, the natural shape of the missing extremity can be reproduced well. Reinforcement layers made of plastic can be arranged in partial areas on the inside of the molded body. These can be used to form the joints or to reinforce stressed areas, for example the heel area or the foot the shoe is streaked serve. The surface of the molded body is expediently reproduced by the coloring and surface structure of the skin of the missing extremity. In the case of particularly high amputations with, for example, partial pelvic resections, it is advantageous that the prosthesis has fastening straps by means of which it can be connected to the patient's body. The present invention is explained in more detail with reference to the accompanying drawings, which schematically show exemplary embodiments of the invention. 1 schematically shows a side view of a leg prosthesis according to the present invention; 2 shows a partial area of the receptacle of the prosthesis with an elastic partial area; 3 shows the inclusion of a prosthesis with quick-release fasteners; 4 shows an embodiment of the receptacle of the prosthesis with which the length of the receptacle can be changed; 5 shows a sectional view of the view according to FIG. 4 along the section line VV; and FIG. 6 shows a variant of a leg prosthesis with an inflatable molded body. 1 schematically shows a prosthesis for the optical replacement of missing limbs in the illustrated example of a missing leg with a molded body 1 simulating the missing extremity, and a receptacle 2 for connecting the prosthesis to the stump 3 of the missing extremity. According to the invention, the molded body 1 is made of plastic and has no functional purposes. This means that with the help of the present prosthesis, no walking or gripping function has to be performed. Furthermore, the scope of the receptacle 2 for connecting the prosthesis to the stump 3 can be changed, so that the prosthesis can be connected to stumps of different sizes of missing extremities. FIG. 2 shows an embodiment variant of a changeability of the circumference of the receptacle 2, which consists of a partial area 4 of the receptacle 2 made of elastic material. The scope of the receptacle 2 can thus be adapted to a certain extent to stumps 3 of missing extremities of different sizes. A further variant of a change in the circumference of the receptacle 2 is shown in FIG. 3, where the circumference of the receptacle 2 can be fixed with the aid of quick-release fasteners 6, for example Velcro fasteners. For this purpose, for example, the receptacle 2 is placed in two folds in the area 5, and the fold is fixed with the aid of the quick fasteners 6. In this way, a quick and easy connection of the prosthesis to the stump 3 of the missing extremity can also be achieved by older patients. 4 and 5 show an embodiment variant, according to which the receptacle 2 can also be changed in length. This is achieved in that at least a portion of the length of the receptacle is made of elastic material and forms at least one fold 7, which in turn is fixed by quick fasteners 8, in particular Velcro fasteners. Finally, FIG. 6 shows a sectional view of an embodiment variant of the prosthesis, wherein the molded body 1 consists of elastic, air-impermeable plastic material 9 and has at least one valve 10 for inflating the molded body 1. This creates an inflatable prosthesis that is particularly simple and inexpensive to manufacture. Reinforcement layers 11 made of plastic can be arranged on the inside of the molded body 1 at sensitive points. In addition, fastening straps 12 can be arranged for further fastening of the prosthesis to the patient's body. Although the drawings are consistently drawn on leg prostheses, arm prostheses can also be made in accordance with the present invention.
