Multi-part support device for an orthosis

Description

[0001] The present invention relates to orthopedic products, in particular orthoses and support devices for orthoses. The invention provides an improved support device for an orthosis, a method for its manufacture, and an orthosis incorporating a support device according to the invention.

[0002] Orthoses are therapeutic devices used to stabilize or support the movement of body parts. The primary goal of functional orthoses is to restore and / or maintain the mobility of the musculoskeletal system. Orthoses can have a functionally reliable, mobilizing, supportive, movement-limiting, and / or corrective effect on the musculoskeletal system. Orthoses can be used directly post-traumatically, post-operatively, or conservatively, meaning to rebuild, secure, or protect joint function, for example, in cases of degenerative diseases. To achieve the necessary stability for each application, the orthosis incorporates one or more stabilizing elements, which are typically rod-shaped or shell-shaped.The stabilizing elements, designed as shells, surround the body part or joint to be stabilized, for example a limb joint, or the torso in the lumbar region, usually by more than half its circumference.

[0003] The stabilizing elements support the mechanically stabilizing effect of the orthosis. Orthoses with body-part-encompassing stabilizing elements include, for example, functional orthoses for the ankle, knee, hip and thigh, wrist, elbow, and shoulder joints. Such orthoses are characterized by the fact that they generally enclose the body part to be stabilized completely, meaning they typically encompass at least more than half of the body part's circumference. The body-encompassing stabilizing elements designed for such orthoses are usually brace-shaped and have a circumferential cross-section that extends beyond a semicircle (greater than 180 degrees) around the body part being stabilized.

[0004] Stabilizing elements are typically molded from a thermoplastic or thermosetting plastic or composite material. Such non-flat or shell-shaped braces, designed to encompass the body or body part, feature an undercut. Manufacturing these types of three-dimensional structures is technically challenging. In established manufacturing processes, body- or body-part-encompassing braces are usually formed from flat blanks (sheets) through thermoforming, particularly deep drawing, into their final three-dimensional shape (user conformity). This manufacturing process is complex and generally requires significant material and labor input. Stabilizing braces for orthoses manufactured using these established methods are not amenable to alternative, and especially not more economical, manufacturing techniques.There is therefore a need to provide improved stabilizing elements for orthoses that can be manufactured using simpler and more economical manufacturing techniques and that have at least equivalent and preferably improved functional properties compared to known stabilizing elements.

[0005] The prior art includes plastic injection molding technology for the production of stabilizing elements for orthoses. However, injection-molded elements are generally essentially flat small parts, add-on components, or shells that are not related to a body-encompassing stabilizing element.

[0006] The technical problem underlying the invention therefore consists in particular in further developing a support device for a body- or body-part-encompassing orthosis in such a way that it is easier and more economical to manufacture and, depending on the specific design, can simplify the application and / or expand the range of functions of the orthosis.

[0007] The technical problem is solved by the subject matter of the independent claims.

[0008] The present invention relates in particular to a support device according to claim 1.

[0009] This particular design of the body-enclosing support device according to the present invention advantageously makes it possible to achieve the desired shape and function of the support device by positively interlocking two shell elements. This allows for simple and economical production of the individual shell elements using injection molding, while simultaneously maintaining or improving the functionality and stability of one-piece support devices for orthoses. A particular advantage is that the assembly, i.e., the positive interlocking connection, of the two shell elements to obtain the support device according to the invention can be carried out without tools, in particular by hand.In a preferred embodiment, the at least two locking connections by which the two shell elements of the device according to the invention are connected to each other cannot subsequently be released without considerable effort.
