Abstract

A socket (110) for upper limb prosthesis comprises a rigid reinforcing member (210) between two silicone-coated supporting layers, and a thin layer of foam padding. The reinforcing member, made from resin reinforced with glass or carbon fibres and molded on a 'positive' corresponding to the shape of the amputee's stump, is connected by an intermediate component to an artificial elbow or hand. A socket (110) for upper limb prosthesis consists of a rigid reinforcing member (210) between two silicone-coated supporting layers and includes a thin layer of foam padding. The reinforcing member, made from resin reinforced with glass or carbon fibres and molded on a 'positive' corresponding to the shape of the amputee's stump, is connected by an intermediate component to an artificial elbow or hand, while the supporting layers are of a silicone coated woven fabric. Where the prosthesis uses myoelectric control, the reinforcing member has at least one generally rectangular or circular cut out for the connection of electrodes opposite the appropriate muscles. An Independent claim is also included for a method of producing the socket.

Description

<Desc / Clms Page number 1>

The present invention relates to a flexible socket for prosthetics of a person with an amputated hand, forearm or arm, that is to say to receive the corresponding stump.

Previously, the sockets used for fitting the limbs of a limb, or part of a limb, were made of materials giving a more or less rigid shape depending on their nature: plastics and, in a somewhat apart, the combination of leather and a metal.

The difficulties encountered then by the amputees were mainly: - the difficulty of introducing the stump into the socket, - the difficulty of placing the electrodes in contact with the skin, opposite the cuts made in the removable sleeve, in the case of myoelectric prostheses with a removable sleeve, - the discomfort of the amputee fitted: in fact, the shape of the muscle masses changes according to the position and joint of the limb; however, the muscular masses of an amputee are constrained in his prosthesis, even during simple changes of position of the limb.

On connaît déjà un dispositif permettant de pallier, pour les amputés fémoraux, aux inconvénients ci-dessus évoqués, tel que celui décrit dans le brevet français 2 539 616 concernant une emboîture souple destinée à la prothétisation d'un amputé trans-fémoral. Cette emboîture est constituée, pour l'essentiel, d'une armature rigide, configurée selon chaque moignon, incluse entre deux couches de supports enduits de silicone. Cette armature est, dans ce domaine particulier, reliée par une pièce intermédiaire au bloc du genou. Un robinet ou une ventouse permet, si besoin, de chasser l'air emprisonné dans le fond de l'emboîture, lors de l'introduction du moignon dans celle-ci. Les parties antérieure et postérieure de l'emboîture sont souples et peuvent ainsi se déformer et se tendre, ainsi que le collet d'emboîture.

A device is already known which overcomes, for the femoral amputees, the drawbacks mentioned above, such as that described in French patent 2,539,616 concerning a flexible socket intended for prosthetizing a trans-femoral amputee. This socket consists essentially of a rigid frame, configured according to each stump, included between two layers of supports coated with silicone. This frame is, in this particular area, connected by an intermediate piece to the knee block. A tap or a suction cup allows, if necessary, to expel the air trapped in the bottom of the socket, during the introduction of the stump therein. The front and rear parts of the socket are flexible and can thus deform and stretch, as can the socket collar.

The invention aims to remedy these drawbacks with regard particularly to the fitting of persons with a hand, forearm or arm amputation. This invention therefore aims, on the one hand, to achieve a comfortable socket of which only the rigid reinforcement, variable in its shape and its cutouts, ensures the resistance and the joining with the connecting parts: elbow, wrist and hand, and, on the other hand, to provide said socket with flexibility facilitating its self-adaptation to variations in shape of the stump, while ensuring, permanently, a good containment thereof.

The flexible socket for prosthetizing a person with an arm or forearm amputation, according to the invention, is con-

<Desc / Clms Page number 3>

 consisting essentially of a rigid frame, included between two layers of supports coated with silicone, with possible interposition of a film of foam padding; said frame being connected by an intermediate piece to the elbow or to the artificial hand; is characterized, mainly, in that the frame is made of acrylic resin, reinforced with glass or carbon fibers, molded on a "positive" corresponding to the shape of the stump to be fitted, and in that the support layers are made of a "woven" coated with silicone.

The frame is delimited according to the particularities of shape and dimensions of each stump.

The rigid frame and the deep layer of the socket comprise, in the case of a myoelectric prosthesis with removable sleeve, at least one generally rectangular or circular cut, allowing the electrodes to come into contact with the skin. The removable sleeve has the same cutout (s). These electrodes are fixed on the rigid framework and are in contact with the medial and lateral epicondylar muscles.

In the case of a hand amputee, the armature corresponds, depending on the shape and dimensions of the stump, mainly to the following alternative embodiments: - delimitation, at its lower end, by a part matching the shape of the end of the stump and attached to the prosthetic wrist, at its upper end, by two rounded parts

 dies placed opposite the medial and lateral faces of the stump and having two large indentations revealing almost the anterior and posterior faces of said stump - delimitation, at its lower end, by a part matching the shape of the end of the stump attached to the prosthetic wrist, at its upper end, by a wide and deep notch revealing the anterior face of the stump and by an opening revealing the posterior face of said stump, - delimitation, at its lower end, by a part conforming to the shape of the end of the stump fixed to the prosthetic wrist, at its upper end, by a wide and deep notch revealing the posterior face of the stump and by an opening revealing the anterior face of said stump, In the case of an amputation of the forearm, the frame corresponds, depending on the shape and dimensions of the stump, mainly in the following variant embodiments s: - delimitation, at its lower end, by a part matching the shape of the end of the stump, at its upper end, by two opposite shells taking the shape of the elbow and, transversely, by two large curvilinear notches, uncovering the faces anterior and posterior stump, - delimitation, at its lower end, by a part

The process for producing the flexible socket for prosthetizing a person with an amputated hand, forearm or arm according to the invention, essentially consisting of a frame rigid, enclosed between two layers of silicone-coated supports, with interposition of a film of foam padding; said frame being connected to the prosthesis by an intermediate piece, is characterized, mainly, in that it consists in carrying out, in order, the following steps: a) carrying out a molding of the stump, with corrected reproduction of the latter, b) placing a tubular woven fabric on the molding, c) coating the tubular woven fabric with a layer of silicone, d) after polymerization of the first layer of silicone, coating of a second layer of silicone, to obtain the first support layer,

<Desc / Clms Page number 8>

 e) making the armature of reinforced synthetic resin, f) placing the armature on the first support layer produced in steps b to d, g) as appropriate, placing the electrodes in the cutouts of the '' reinforcement provided for this purpose, h) interleaving of a foam padding film on all contacting surfaces, i) spreading of a "primer" on the foam film and on the reinforcement, j) placement , on the assembly obtained during the previous steps, of a tubular woven impregnated with silicone, constituting the second layer The advantages obtained, thanks to the invention, consist essentially in that the flexible socket adapts perfectly to the stump, without any discomfort for the amputee, without interposition of additional element intended to fill a possible space between stump and socket; the frame of this socket is, moreover, designed, in each case, to allow a free deformation of the muscle masses in all the zones where it can be permitted, while preserving a sufficient attachment of the stump to the prosthesis and leaving the amputated free joint movement.
