Abstract

According to the invention, the substantially cylindrical sheath has a cord (4) fixed to its upper part, making it possible to withdraw it after the stump has been fitted into the prosthesis.

Description

GAINE DE CHAUSSAGE DE PROTHESE. PROSTHETIC SHOE SHEATH.

La présente invention a pour objet une gaine de chaussage de prothèse destinée en particulier, mais non exclusivement, à la mise en place d'une prothèse de contact cuisse.The present invention relates to a prosthesis sheath intended in particular, but not exclusively, for the establishment of a thigh contact prosthesis.

Les prothèses de contact, notamment de cuisse, sont des prothèses maintenues sur le moignon par succion. A cet effet, elles comprennent au niveau qui sera celui de la partie inférieure du moignon une valve permettant d'évacuer l'air qui se trouve entre la partie inférieure de la chambre ou embolture et le moignon de sorte que ces deux éléments sont solidarisés par la pression atmosphérique. Ce type de prothèse est également désigné par prothèse à sussion.Contact prostheses, especially of the thigh, are prostheses held on the stump by suction. For this purpose, they comprise at the level which will be that of the lower part of the stump a valve making it possible to evacuate the air which is between the lower part of the chamber or embolture and the stump so that these two elements are joined together by atmospheric pressure. This type of prosthesis is also referred to as a percussion prosthesis.

Son usage suppose toutefois un assujetissement parfait du moignon dans l'emboîture de prothèse. Or, lors de l'introduction de celle-ci dans l'emboîture, les chairs se déforment ce qui conduit à des sensations douloureuses lors du port de la prothèse pendant un temps assez long, ainsi qu'à la perte de l'effet de succion et donc de la prothèse.However, its use presupposes a perfect subjection of the stump into the prosthesis socket. However, during the introduction of the latter into the socket, the flesh deforms which leads to painful sensations when wearing the prosthesis for a fairly long time, as well as to the loss of the effect of suction and therefore of the prosthesis.

La présente invention a pour objet de pallier cet inconvénient et de permettre un bon positionnement du moignon, une répartition des chairs homogènes à l'intérieur de l'emboiture de la prothèse.The object of the present invention is to overcome this drawback and to allow proper positioning of the stump, a distribution of homogeneous flesh inside the socket of the prosthesis.

Selon la présente invention, la gaine de chaussage de prothèse est caractérisée en ce qu'elle est constituée par un tricot cylindrique fermé à sa partie inférieure et ouvert à sa partie supérieure, un cordon de tirage dont la longueur est supérieure à deux fois la hauteur du tricot étant relié par ses extrêmités au bord supérieur dudit tricot. According to the present invention, the prosthesis sheath is characterized in that it is constituted by a cylindrical knit closed at its lower part and open at its upper part, a pull cord whose length is greater than twice the height knitting being connected by its ends to the upper edge of said knitting.

Ainsi, la personne amputée après avoir enfilé la gaine sur le moignon introduit le bas du cordon dans le trou d'ouverture de la soupape, puis tire sur celui-ci ce qui entralne la gaine à se replier sur elle-meme jusqu'à ce qu'elle soit complètement dégagée du moignon. Elle est ainsi extraite par le trou de la soupape.Thus, the amputee after having put the sheath on the stump introduces the bottom of the cord into the opening hole of the valve, then pulls on it which causes the sheath to fold in on itself until that it is completely clear of the stump. It is thus extracted through the hole in the valve.

Selon une autre caractéristique de l'invention, le tricot est extensible latéralement et indéformable longitudinalement de sorte qu'il ne puisse glisser sur lui-même qu'en direction longitudinale. Dans ces conditions, le retournement de la gaine sur elle-même ne produit aucune déformation et la répartition des chairs dans l'emboîture reste telle qu'elle était lors du chaussage de la prothèse.According to another characteristic of the invention, the knitted fabric is laterally extensible and longitudinally non-deformable so that it can slide on itself only in the longitudinal direction. Under these conditions, the reversal of the sheath on itself produces no deformation and the distribution of the flesh in the socket remains as it was during the fitting of the prosthesis.

D'autres caractéristiques et avantages de l'invention apparaîtront au cours de la description qui va suivre de modes particuliers de réalisation donnés à titre d'exemples non limitatifs en regard des figures qui représentent - La figure 1, une gaine selon l'invention; - les figures 2 à 5 des schémas montrant la mise en place et
l'extraction d'une telle gaine.Other characteristics and advantages of the invention will appear during the description which follows of particular embodiments given by way of nonlimiting examples with reference to the figures which represent - FIG. 1, a sheath according to the invention; - Figures 2 to 5 of the diagrams showing the installation and
the extraction of such a sheath.

Sur la figure 1, on voit que la gaine est constituée par un tricot 1 de fils de nylon, par exemple, de forme générale tronconique, terminé à sa partie supérieure par un revers 2 et à sa partie inférieure par un talon 3 qui renforce celle-ci. Le tricot 1 est extensible latéralement, de manière à pouvoir épouser la forme du moignon mais non longitudinalement. Un cordon 4, dont la longueur est supérieure a deux fois la hauteur du tricot est relié par couture de ses extrêmités sur le revers 2. In FIG. 1, it can be seen that the sheath consists of a knitted fabric 1 of nylon threads, for example, of generally frustoconical shape, terminated at its upper part by a cuff 2 and at its lower part by a heel 3 which reinforces that -this. The knit 1 is extendable laterally, so as to be able to follow the shape of the stump but not longitudinally. A cord 4, the length of which is greater than twice the height of the knitted fabric, is connected by sewing its ends to the lapel 2.

La texture du tricot du slipper fait qu'il n'y a qu'une élasticité transversale. De plus celle-ci ne laisse glisser le tricot sur lui-même que dans le sens longitudinal sans qu'il y ait de glissement possible latéralement.The texture of the knit of the slipper means that there is only transverse elasticity. In addition it allows the knitting to slide on itself only in the longitudinal direction without there being possible sliding laterally.

La figure 2 représente un moignon revêtu d'une gaine selon l'invention. La gaine 1 est très fine (de l'épaisseur d'un bas de soie ou nylon par exemple) mais, sur les schémas cette épaisseur a été volontairement exagérée pour permettre la compréhension.FIG. 2 represents a stump coated with a sheath according to the invention. The sheath 1 is very thin (the thickness of a silk or nylon stocking for example) but, in the diagrams, this thickness has been deliberately exaggerated to allow understanding.

Lors de l'introduction du moignon dans l'emboîture 6, on prend soin de faire passer le cordon 4 à travers le trou 5.When introducing the stump into the socket 6, care is taken to pass the cord 4 through the hole 5.

(figure 3).(figure 3).

Après emboltement convenable du moignon dans la prothèse, on tire alors sur le cordon 4 ce qui entralne le déroulement de la gaine 1 sur le moignon comme représentée sur la figure 4.After proper embolism of the stump in the prosthesis, the cord 4 is then pulled, which entrains the course of the sheath 1 on the stump as shown in FIG. 4.

Comme indiqué précédemment, et grâce à la texture spécifique du tricot, la gaine glisse dans le sens longitudinal, c'est à dire le long du moignon en se retournant sur elle-même.As indicated previously, and thanks to the specific texture of the knitting, the sheath slides in the longitudinal direction, that is to say along the stump while turning on itself.

Lors de la traction, la gaine 1 suit le cordon 4 à travers le trou 5 et peut ainsi être complètement extraite de l'emboîture 6 par le trou de la valve 5. Comme la gaine ne peut glisser que longitudinalement, les chairs du moignon restent dans leur position d'origine. Après quoi, on obture le trou par une soupape 7 comme représenté sur la figure 5.When pulling, the sheath 1 follows the cord 4 through the hole 5 and can thus be completely extracted from the socket 6 by the hole in the valve 5. As the sheath can only slide longitudinally, the stumps of the stump remain in their original position. After which, the hole is closed by a valve 7 as shown in FIG. 5.

Les amputés bénéficient ainsi d'un moyen permettant d'assurer un chaussage de la prothèse qui ne crée aucune déformation des chairs du moignon, et qui permet donc un chaussage avec une parfaite répartition des chairs évitant ainsi toute contrainte supplémentaire sur le moignon. The amputees thus benefit from a means enabling the prosthesis to be fitted, which does not cause any deformation of the stump flesh, and which therefore allows a fitting with a perfect distribution of the flesh, thus avoiding any additional stress on the stump.

Il va de soi que de nombreuses variantes peuvent être introduites notamment par substitution de moyens techniquement équivalents sans pour autant sortir du cadre de l'invention. It goes without saying that many variants can be introduced in particular by substitution of technically equivalent means without departing from the scope of the invention.
