Description

La présente invention Concerne un dispositif de maintient dynamique de l’ouverture de la première commissure de la main humaine.The present invention relates to a device for dynamically maintaining the opening of the first commissure of the human hand.

L’ouverture de la première commissure de la main est naturellement effectuée par les muscles intrinsèques de la main et les muscles de l’avant-bras. La charnière de cette ouverture est assurée par la présence de l’articulation trapézo-métacarpienne. Au fur et à mesure du vieillissement naturel, cette articulation se dégrade et devient source de douleurs. Il s’en suit une limitation douloureuse de l’ouverture de cette commissure. Ceci se traduit concrètement par une limitation de la préhension des objets et donc une limitation des activités quelles soient quotidiennes, de loisirs, sportives.The opening of the first commissure of the hand is naturally carried out by the intrinsic muscles of the hand and the muscles of the forearm. The hinge of this opening is ensured by the presence of the trapezio-metacarpal joint. As natural aging progresses, this joint deteriorates and becomes a source of pain. This results in a painful limitation of the opening of this commissure. This translates concretely into a limitation of the gripping of objects and therefore a limitation of activities, whether daily, leisure or sporting.

Les dispositifs existants sont uniquement disposés sur la colonne du pouce, augmentant la pression axiale de l’articulation trapézo-métacarpienne. La première commissure est libre. Ils sont statiques.Existing devices are only placed on the column of the thumb, increasing the axial pressure of the trapezio-metacarpal joint. The first commissure is free. They are static.

Le dispositif selon l’invention permet de limiter ces inconvénients. Il comporte en effet selon une première caractéristique un « bloc dynamique » anatomique. Celui-ci vient s’appliquer dans la première commissure. De par sa forme et sa structure il vient automatiquement garder l’ouverture de cette commissure sans aucune action musculaire. Il crée ainsi un deuxième axe de rotation et permet de limiter les contraintes mécaniques de l’articulation trapézo-métarcapienne. Ledit dispositif possède aussi des caractéristiques mécaniques absorbantes. Il permet donc de limiter les chocs extérieurs (vibrations) qui peuvent se répercuter sur l’articulation trapézo-métarcapienne. Ceci a pour finalité clinique de limiter les douleurs et d’améliorer la fonction de préhension de la main.The device according to the invention makes it possible to limit these disadvantages. In fact, according to a first characteristic, it comprises an anatomical “dynamic block”. This comes to apply in the first commissure. Due to its shape and structure, it automatically keeps the opening of this commissure without any muscular action. It thus creates a second axis of rotation and makes it possible to limit the mechanical stresses of the trapezio-metarcapian joint. Said device also has absorbent mechanical characteristics. It therefore makes it possible to limit external shocks (vibrations) which can affect the trapezio-metarcapal joint. This has the clinical purpose of limiting pain and improving the gripping function of the hand.

Selon les modes particuliers de réalisation ce « bloc dynamique » sera stabilisé dans la première commissure par un fourreau élastique enveloppant la main. Un emplacement spécifique (poche) dans ce fourreau lui assure une bonne stabilité lors de l’utilisation. Ceci permet aussi d’améliorer son rôle dynamique en limitant sa déformation.According to particular embodiments, this “dynamic block” will be stabilized in the first commissure by an elastic sheath enveloping the hand. A specific location (pocket) in this sheath ensures good stability during use. This also improves its dynamic role by limiting its deformation.

La représente la deuxième version du dispositif de l’invention en place sur la main.There represents the second version of the device of the invention in place on the hand.

La représente le centre naturel de rotation (a) de la colonne du pouce soit l’articulation trapézo-métacarpienne, ainsi que le deuxième centre de rotation (b) crée par notre « bloc dynamique ».There represents the natural center of rotation (a) of the thumb column, i.e. the trapezio-metacarpal joint, as well as the second center of rotation (b) created by our "dynamic block".

En référence à ces dessins, le dispositif est réalisé en une seule étape de tricotage. La poche est tricotée en même temps que le tricot, sans créer de surcouche, ni nécessité de couture ( ). Un fil fusible intégré au tricot permet d’ouvrir la poche lors du vaporisage du tricot afin de la rendre accessible. Cette ouverture de poche permet de positionner le bloc dynamique ( ), sans confection supplémentaire.With reference to these drawings, the device is produced in a single knitting step. The pocket is knitted at the same time as the knitting, without creating an overlay, nor the need for sewing ( ). A fusible thread integrated into the knit allows the pocket to be opened when steaming the knit to make it accessible. This pocket opening makes it possible to position the dynamic block ( ), without additional tailoring.

A titre d’exemple non limitatif, le bloc dynamique est actuellement en Silicone.By way of non-limiting example, the dynamic block is currently made of Silicone.

Afin d’améliorer le confort du dispositif une fixation par bandelettes fines, passant par 2 ouvertures situées dans le « bloc dynamique », est aussi prévue ( et 5). Ces bandelettes font ensuite le tour de la main pour stabiliser le dispositif lors des mouvements.In order to improve the comfort of the device, a fixing by thin strips, passing through 2 openings located in the "dynamic block", is also provided ( and 5). These strips then go around the hand to stabilize the device during movement.

Les dimensions et la forme du « bloc dynamique » peuvent évoluer en fonction de la taille de la main. L’épaisseur variable de celui-ci ainsi que les différents matériaux utilisés permettent de faire varier la déformation élastique du « bloc dynamique ». Ceci permet de faire évoluer le dispositif en fonction des objectifs recherchés. Une plus grande souplesse du « bloc dynamique » apportera du confort alors qu’une rigidité augmentée permettra d’améliorer les mouvements de force (sports...).The dimensions and shape of the “dynamic block” may change depending on the size of the hand. Its variable thickness and the different materials used make it possible to vary the elastic deformation of the “dynamic block”. This makes it possible to develop the device according to the objectives sought. Greater flexibility of the "dynamic block" will provide comfort while increased rigidity will improve movement of strength (sports...).

Le « bloc dynamique » crée par sa présence un deuxième axe de rotation ( / b) du pouce. Il permet ainsi de diminuer les contraintes mécaniques s’exerçant sur l’axe anatomique du pouce ( / a) que représente l’articulation trapézo-métacarpienne, la finalité étant une diminution des douleurs.The "dynamic block" creates by its presence a second axis of rotation ( / b) thumb. It thus makes it possible to reduce the mechanical stresses exerted on the anatomical axis of the thumb ( / a) represented by the trapezio-metacarpal joint, the purpose being a reduction in pain.

Le dispositif selon l’invention est particulièrement destiné au maintient dynamique de l’ouverture de la première commissure de la main chez les personnes souffrant de rhizarthrose.The device according to the invention is particularly intended for the dynamic maintenance of the opening of the first commissure of the hand in persons suffering from rhizarthrosis.
