    Field of the Invention
    The invention relates to an improved knee joint bandage comprising correction strips to stabilize the patella (patella). According to the invention, the correction strip is adjustable in relation to its effect on the patella.
    The knee joint bandage provided here mainly serves to correct the position of the kneecap by a target, adjustable mechanical impact of force. Knee joint bandages comprising an elastic textile material for stabilizing the knee joint are known, which are pulled like a sock along the knee joint. Often such bandages show a recess comprising a profiled insert (pellet), which is arranged in or in the textile material. In connection with the force generated by the elasticity of the bandage tissue on the knee joint, the profiled insert serves mainly to mechanically stabilize the knee joint, drain water from the tissue present due to inflammatory events and / or to ensure the physiologically correct position of the kneecap on the knee. This is for the therapy of damaged knee joints. The bandage can also be used to prevent further damage to the knee joint.
    In order to improve the function of such knee joint bandages, they comprise for stabilizing the position of the patella at least one non-elastic tension member foldable in the form of a correction strip, which essentially connects the sections of the kneecap poles in the fibula side (outer side of the knee, lateral) arched around the patella, such that an increase in the distance of one of these sections (moving away), in the context with the knee joint doubling the arc distance of the correction strip of the patella is reduced, so that it is displaced medially or pushed to the center of the knee and / or fixed here in a physiologically correct position. Such knee joint bandages are described in DE 38 38 576 Al and DE 10 2004 040 793 Al.
    In such knee joint bandages, it is particularly disadvantageous that the medially centering effect of the brace is not sufficient for many applications. In certain movements and / or certain types of damage to the knee joint to be treated, the effect is too weak for any beneficial preventive or therapeutic effect to occur. In addition, under certain other conditions of movement, for example, when sitting with a bent knee, pressure is often applied to the kneecap which is experienced as too strong and potentially harmful to therapy. Accordingly, it is desirable to provide a knee bandage of the aforementioned type that avoids these inconveniences. The invention is based on the technical problem of providing an elastic knee joint bandage in which the displacement force applied to the patella by a correction strip arranged in the knee joint bandage can be beneficially adjusted for the respective therapeutic and prophylactic conditions. to improve therapeutic success.
    The invention completely addresses the underlying technical problem in a bandage for a knee joint, which comprises a textile elastic stocking and a profiled elastic insert arranged in or in the textile stocking similar to a ring or clasp, which houses at least one side section of the knee joint, that is, on the fibula side, as well as at least one elastic band, which essentially extends in the longitudinal direction of the bandage over the knee joint, which is flexible but not elastic, which is guided laterally or along the profiled insert. The traction strip has an upper end and a lower end, with at least one end being fixed by at least one upper anchoring point 5 and / or one lower anchoring point to a textile sock, detachable, particularly in an adjustable way . In a section between the upper end and the lower end of the traction strip, a force can be applied to the knee cap when the bandage is worn, which can move the patella to its normal and physiologically safe (fixed) position on it.
    If the traction force is applied to at least one end of the anchored traction strip, which in a fabric bandage is generated mainly when the knee 15 is bent by anchoring points that move beyond, it acts on the section as a retor of force of displacement or fixation of the patella. Particularly on a damaged knee the fixation effect is based here on a displacement force acting on the joint on the knee cap 20 to be neutralized by an applied counter-force properly adjusted by the traction strip, which opposes the displacement of the patella.
    The invention is primarily characterized by the effective length between the ends of the tension strip being adjustable along a clamping force, not locally fixed or adjustable, of at least one end of the tension strip, in order to control the displacement or fixing the force applied to the patella. The force that the traction strip can be applied on the kneecap depends on its effective length. This defines the effective length of the traction strap arc, which applies force to the knee cap when the ends connected to the anchor points separate when the knee is bent. The effective short duration is equivalent to a stretched elastic band, when the bandage is used, which can apply a greater force, a longer effective length is equivalent to a less stretched elastic band during its use, which applies a lesser force in the patella.
    The invention therefore provides to realize the traction strip, in such a way that it can be altered in its effective length, in order to allow the predetermined displacement or to fix the effect of the elastic strap and, thus, the bandage on the kneecap. knee, according to the respective disease, the therapeutic approach, the movement condition, the progression of the therapy, the therapeutic schedule, etc., in particular, individually for each patient.
    In a first bandage modality, at least the upper end of the traction strip, that is, the end that points to the trunk, is fixed at different optional points at one of the several distant anchoring points. For example, the various anchoring points, mainly arranged one behind the other in the direction of the extension of the tension strip, can alternatively be detachably connected, in order in this way to control the effective length of the tension strip. In another variant of this modality, alternatively, only the lower end of the elastic strap can be fixed, respectively, in a locally adjustable way. In another variant, both ends of the elastic strap can be fixed in an adjustable manner respectively locally.
    Preferably, the locally adjustable fastening is implemented through a detachable connection selected from velcro, buttons and hook / eye system. Although, the detachable connection is not limited to these structures only. A person skilled in the art knows other detachable connections that can easily be used in particular in the field of textile bandages.
    It may be provided to mark the alternative anchoring points for an adjustable fixation of the traction strip by coloring or using numbers or symbols, so that, if applicable, the patient (he / she) can simply perform the effective length adjustment of the traction strip easily and reliably, after the previous instruction by the doctor or orthopedic technician, for example, depending on the therapeutic requirements, therapy of predetermined times, and / or current conditions of movement of the patient.
    In another variant, the locally adjustable fixation of the traction strip is also carried out in at least one winding provided in or near the anchoring points, in order to adjust the effective length. Such a winding mechanism can additionally be provided with a locking stop mechanism against a resistance, known per se. In another alternative embodiment, a pulley mechanism, known per se, is provided at the anchoring points, in order to further improve the adaptability, particularly to relieve the force required for such changes.
    The invention provides that the traction strip, although flexible, is essentially inelastic. In the sense of the present invention, non-elastic means means above all that the modulus of elasticity of the traction belt material and / or the internal structure of the traction strip is considerably greater compared to the other elastic materials used in the bandage, particularly textile and profiled insertion, here particularly for one or more orders of ten. Although the preferred materials for a profile insert are, for example, silicone elastomers, with an average hardness of shore A, for example, 30 to 60 of shore A, the traction strip must be produced, for example, under the in the form of a thread, rope, or web comprising a hard material, such as steel or nylon. A person skilled in the art knows other similar materials, and structures, which, in the sense of the invention, are also suitable for implementing the traction strip used according to the invention; the invention also includes these additional materials and structures.
    In a particular embodiment, the traction strip is guided in a strong sliding channel arranged in or in the profiled insert. It can be permanently connected to the profiled insert and is particularly realized so that the lateral forces applied through the traction strip when using the bandage cannot act directly on the profiled insert, by which it could be destroyed, particularly, once here , during the frictional forces of use, cutting like knives, develop between the tension strip and the profiled insert filling material. Preferably, the sliding channel is incorporated in the form of a tube or a groove, that is to say made of a mechanically resistant and friction resistant material, for example, Teflon, nylon, which allows less friction of sliding of the traction strip , avoiding abrasion of the material.
    In another embodiment, the orientation channel itself is also elastic. Here, the modulus of elasticity of the material of the guide channel is selected, such that it corresponds to the modulus of elasticity of the profiled insert, so that shear forces are particularly avoided, which disturbs the connection between the guide channel. and profiled insertion.
    In an alternative embodiment, the traction strip is fixed locally to the interior or to the profiled insert. In this way, friction and cutting forces acting on the filling material can be avoided, the filling material follows the movement of the tension strip at the limit between the tension strip and the profiled insert. For example, the pull strip can be launched into the profiled insert material. Alternatively, the elastic strip can be glued or welded on the profiled insert or the filling cover of the profiled insert. In a particular embodiment, the traction strip is arranged in such a way that it extends, in the applied state between the profiled insert and the knee, in order, essentially, directly in contact with the patella to be corrected or fixed. For this purpose, for example, the traction strip can extend directly into or within the filling cover disposed between the profiled insert and the patella. Preferably, the traction strip is sewn or welded to said traction strip. Alternatively or additionally, the traction strip itself is covered directly with a filler in order to avoid any mechanical irritation on the skin. This can be advantageous when, alternatively, the traction strip extends along the outside of the profiled insert, preferably directly at the knee joint. For example, the traction strip is formed from nylon thread with silicone coating, forming a strip of fabric covered with silicone elastomer.
    In another additional or alternative embodiment, the traction strip is incorporated interchangeably in the bandage. It can be incorporated in alternative thicknesses, lengths and / or degrees of elasticity for use in the same bandage. For example, it may be necessary in the same bandage for a while to use it harder and harder and another for a more elastic traction strip, depending on the movement condition. In this way, the effect of the traction strip is beyond the possibility of adjusting the ends of the traction strip, it can also be adjusted over a longer interval, in order to further improve the ability to adjust the function of the articulation bandage. of the knee.
    In a particular embodiment, it is envisaged that the traction strip extends in the area of the patella laterally inward, that is, the interior area of the bandage facing the knee, and at least leaves a crossing point the bandage out of the inside of the textile sock and then extends outside the bandage, so that the outer area in front of the knee, here, preferably, in the textile sock itself to be anchored in at least one anchoring point. Thus, advantageously, the adjustment of the effective length is also possible, when the bandage is worn. In addition, it can be avoided in this way that the means that incorporates the detachable connection, locally variable, according to the invention must be arranged inside the bandage, which facing the body, which here can disadvantageously be connected local, mechanical irritation of the skin. However, the invention is not limited to externally located detachable connecting means or an outer progression of at least one end of the traction strip.
    In particular, it is envisaged that one end of the traction strip is fitted locally directly attached to the or the textile sock in a non-detachable or adjustable manner, while the other end is fixed in an adjustable manner, according to the invention. For this purpose, the traction strip is preferably sewn, glued, or welded to the textile sock. In a preferred embodiment, the lower end of the traction strip is welded or glued to the textile sock and the upper end of the traction strip is guided from the inside to the outside of the bandage, where it is easily accessible by the user and can be attached to its end in an adjustable way.
    In one embodiment of the bandage, it shows at least one spring plane stabilizing element in or within the textile sock on the side of the bandage that extends the longitudinal extent of the bandage, in order to stabilize the knee joint bandage itself in a manner mechanics.
    In a particular embodiment of such an embodiment, it is now envisaged that at least one of the attachment points at the end of the traction strip is directly connected to the flat spring element in a form of adjusting force.
    In this way, a better local fixation of the traction strap can be achieved, which improves the application of force on the traction strap by flexion of the knee and, thus, also, the mechanical effect on the patella.
    The bandage helps to relieve pain caused by a failure to position the kneecap. Advantageously, the wear and tear of the knee joint cartilage, located behind the kneecap can be prevented. The purpose of the invention also includes the medical, therapeutic and / or prophylactic use of the bandage, according to the invention for the prophylaxis, attenuation, and / or therapy of diseases of the joints of the animal or human body, particularly diseases of the joint of the knee, which are linked to a harmful displacement of the patella. This particularly includes, lateralization of the patella, patellar dysplasia, retropatellar arthritis, patellar chondropathy, acute patella syndrome, patellar chondromalacia, state after patellar dislocation, as well as post-traumatic and postoperative conditions.
    The invention is explained in more detail in the figures and in the corresponding description, without being limited to them.
