REVERSIBLE CLOSABLE EXTREMITY ORTHOSE OR BANDAGE OR SPORTS AID

Description

[0001] The present invention relates to an extremity orthosis or bandage or a sports aid, comprising a tensioning system consisting of a first tensioning element system and a second tensioning element system, wherein the first tensioning element system and the second tensioning element system are each reversibly lockable.

[0002] Orthoses and bandages for extremities, also called extremity orthoses or bandages, in particular knee orthoses for passive and active stabilization of the knee joint, but also elbow orthoses, are known from the prior art. Such knee orthoses often have a support element in the form of a bandage onto which stabilizing elements such as straps, rods or joint splints are mounted, as shown, for example, in DE 200 05 366 U1.

[0003] Knee braces are used, for example, in cases of knee osteoarthritis or after a medial meniscus injury to relieve and stabilize the affected area. Knee braces often feature straps that allow them to be adjusted to the shape of the leg and / or the area of ​​application. Specifically guided tensioning systems are known, for example, from EP 2 612 626 A2, DE 40 136 93 A1, DE 10 2017 220 968 A1, WO 1996 / 16615 A1, and DE 198 44 545 A1. US 8,277,401 B2 discloses a brace with a tensioning system consisting of two tensioning element systems.

[0004] These tensioning systems require the wearer, especially the patient, to step into the tensioning system with their extremity, especially their leg, when putting on the orthosis or bandage, and to step out when taking it off, which can be complicated and particularly uncomfortable and dangerous for patients.

[0005] The problem underlying the present invention is the provision of an extremity orthosis or bandage, in particular a knee orthosis or bandage, which overcomes the problems of the prior art and in particular enables easier and safer putting on and taking off of the orthosis or bandage.

[0006] The present invention solves the underlying technical problem by means of an extremity orthosis or bandage or a sports aid according to claim 1.

[0007] All the following embodiments for an extremity orthosis or extremity bandage according to the invention are also disclosed for sports aids according to the invention.

[0008] It was found that it is advantageously possible to provide a fully functional tensioning system that is reversibly lockable and unlockable. This allows the wearer, especially the patient, to advantageously place and close the tensioning system around the extremity, particularly the leg, when putting on the orthosis or bandage, thus eliminating the need to step into the system with the leg or insert the arm. The same applies when removing the orthosis or bandage, where the tensioning system can be reopened and removed without the wearer, especially the patient, having to pull the extremity out of the system.

[0009] In a preferred embodiment, when applying an extremity orthosis or bandage, the first and / or the second tensioning system of the tensioning system are guided around the extremity, in particular a leg, such that the first and / or the second tensioning system of the tensioning system each enclose the extremity. According to the invention, it is particularly provided that the first tensioning system is assigned to the upper part of the extremity, i.e., the thigh or upper arm, and the second tensioning system is assigned to the lower part of the extremity, i.e., the lower leg or forearm, so that the knee or elbow is positioned between the two tensioning systems when the orthosis or bandage is applied.

[0010] In a preferred embodiment, the first clamping element system and the second clamping element system are formed from a single, continuous clamping element. It is therefore advantageously possible to form the extremity orthosis or bandage according to the invention with only a single clamping element.

[0011] Alternatively, it can of course also be provided that the first clamping system is formed from a first clamping element and the second clamping system is formed from a second clamping element.

[0012] In a preferred embodiment, the at least one tensioning element is a strap, a flat band, a rope, a wire, or a Bowden cable.

[0013] The clamping element can be flexible, inflexible, or partially flexible. In a preferred embodiment, the at least one clamping element is inelastic.

[0014] In a preferred embodiment, the at least one tensioning element comprises a rope or a wire, wherein the rope or wire runs at least partially within a sheath, the sheath being slidably mounted on the extremity orthosis or bandage.

[0015] The Bowden cable, and therefore also the cord, can be attached to padding, at least in sections. This padding, for example in the form of a strap or belt, provides significantly greater comfort for the patient and prevents the cord from cutting into the extremity. The padding can be elastic or inelastic. Padding with only partially elastic sections is also possible.

[0016] The at least one tensioning element can also be connected to the padding via rotatably mounted fastening elements. In the preferred embodiment, the padding and the entire cable guide are slightly elastic. In a preferred embodiment, the extremity orthosis or bandage has rotatably mounted deflection guides in which the at least one tensioning element is deflected.

[0017] In a preferred embodiment, the first clamping element system can be reversibly closed by a first coupling device and the second clamping element system by a second coupling device.

[0018] According to the invention, the first clamping element system and the second clamping element system can each be reversibly closed by means of a coupling device, wherein each coupling device comprises a first coupling element and a second coupling element, wherein the first coupling element can be reversibly connected to the second coupling element via a locking system, wherein the first coupling element has a first guide for a clamping element and the second coupling element has a second guide for a clamping element, wherein the clamping element runs in the first guide and the clamping element runs in the second guide, and wherein, in the connected state of the two coupling elements, the first guide and the second guide cross each other at least once, in particular twice.

[0019] The guides cross at least once, and preferably twice, causing the clamping elements within them to also intersect. Therefore, when the two coupling elements are connected, for example to close the orthosis, the two clamping elements guided within them cross over in two different planes. This intersecting clamping elements has the advantage that the coupling elements can be implemented in a relatively small space, and friction is minimized by this design. This also leads to better force distribution within the entire clamping system.

[0020] A preferred double crossing of the guides occurs, for example, when the two guides are curved in opposite directions and overlap. A single crossing of the guides occurs, for example, when the two guides are curved in opposite directions and only overlap at their tips, i.e., the apexes of the curvature.

[0021] Preferably, the first guide has a curvature, in particular a horseshoe shape, and the second guide also has a curvature, in particular a horseshoe shape. Preferably, the two horseshoe-shaped guides overlap when the two coupling elements are connected. Preferably, the two ends of the first horseshoe-shaped guide point away from the second horseshoe-shaped guide, and vice versa.

[0022] The guides can be designed, for example, as tunnels or channels, or even as open tunnels or channels. The guides allow the tensioning elements to cross without contact.

[0023] In a preferred embodiment, the first guide is positioned in the edge region of the first coupling element and the second guide is positioned in the edge region of the second coupling element.

[0024] In a preferred embodiment, the first coupling element has a front and a back and is horseshoe-shaped with a concave inner edge, wherein the second coupling element has a front and a back and is horseshoe-shaped with a concave inner edge, wherein the first coupling element has a first locking element in the region of the apex of the horseshoe shape on the front and the second coupling element has a second locking element in the region of the apex of the horseshoe shape on the back, and wherein the second horseshoe-shaped coupling element has a first web element spanning the concave inner edge of the second coupling element.wherein, in the connected state of the two coupling elements, the first locking element of the first coupling element engages in the first web element of the second coupling element, and the second locking element of the second coupling element engages in the concave inner edge of the first coupling element.

[0025] Preferably, the first coupling element and the second coupling element are displaceable or rotatable relative to each other when the two coupling elements are connected. This has the advantage that the clamping elements are also displaceable relative to each other.

[0026] Preferably, the second coupling element has a second web element spanning the concave inner edge of the second coupling element, which, in the connected state of the two coupling elements, presses the first web element against the first locking element. Preferably, the second web element has an inclined flattening in its central region, which, particularly during bending, can slide under the first web and lift it up or otherwise release it from the locking element.

[0027] Preferably, the first coupling element and the second coupling element are made of plastic.

[0028] It is preferred that the first guide and / or the second guide are designed as a handle element.

[0029] A coupling device is also preferred, wherein the first coupling element is reversibly connected to the second coupling element via the locking system, and the coupling device is opened by pressing the second horseshoe-shaped coupling element together at the arms of the horseshoe-shaped coupling element, thereby preferably pushing the second web element spanning the concave inner edge of the second coupling element towards the tip of the second horseshoe-shaped coupling element and / or towards the first coupling element, and thereby preferably lifting the first web element out of the first locking element, so that the two coupling elements are preferably pushed against each other and can thereby be separated from each other.

[0030] In a preferred embodiment, the extremity orthosis or bandage has a connecting element to which the at least one tensioning element, in particular the single tensioning element or the first tensioning element and / or the second tensioning element, is attached.

[0031] In a preferred embodiment, the at least one clamping element is attached to the connecting element at both ends. In a preferred embodiment, the single clamping element is attached to the connecting element at both ends. With multiple clamping elements, it is also possible for each element to be attached to the connecting element at only one end.

[0032] In a preferred embodiment, the connecting element includes a tension control element for tensioning the at least one clamping element. In a preferred embodiment, the connecting element is a tension control element for tensioning the at least one clamping element.

[0033] It is advantageously provided that the two clamping systems can be clamped together or separately, so that they enable, on the one hand, a firm fit of the orthosis or bandage for extremities on the extremity, in particular the knee orthosis or bandage on the leg, and on the other hand, good positioning and a good fit of a preferred joint splint.

[0034] In a preferred embodiment, the tension control element is designed as a rotary knob with which the clamping element can be tensioned, or both clamping elements can be tensioned simultaneously. Preferably, the clamping elements are tensioned by turning a knob, for example, by winding cables that form the clamping elements through the rotary knob. It is therefore preferred that the two clamping element systems are tensioned simultaneously by a single tension control element, so that both clamping element systems have the same clamping force, thus combining the two clamping element systems into a single clamping system and requiring only one step to tension both clamping element systems.

[0035] Naturally, the tension control element is designed so that the clamping systems can also be released. For example, different tension levels can be set using detents in the rotary knob, thus advantageously enabling specific force adjustment.

[0036] In a preferred embodiment, the at least one clamping element is attached to the tension control element at both ends. However, it can also be attached to the tension control element at only one end. The second end can then be attached to any point on the orthosis.

[0037] Alternatively, a first clamping element can be provided for the first clamping system and a second clamping element for the second clamping system, with each of the two clamping elements being attached at one end to the tension control element and at the other end to any point on the orthosis or bandage, for example on a joint rail.

[0038] In a preferred and advantageous embodiment, the clamping system is guided such that the first clamping element system intersects in a first intersection area and the second clamping element system intersects in a second intersection area. Preferably, the first intersection area is formed by the first coupling device and the second intersection area by the second coupling device.

[0039] Preferably, the first and / or second crossing area is located on the inside of the extremity when worn. Preferably, the first and / or second coupling device is located on the inside of the extremity when worn. Alternatively, the crossing areas and / or the coupling devices can be located on the outside of the extremity, or at the back, or at the front.

[0040] It is therefore preferred that, in the case of the applied extremity orthosis or bandage, the first tensioning element system and / or the second tensioning element system of the tensioning system are guided around the extremity, in particular a leg, in such a way that the first tensioning element system and / or the second tensioning element system of the tensioning system encircles the extremity and crosses itself once.

[0041] The present invention also relates to an extremity orthosis or bandage comprising a tensioning system consisting of a first tensioning element system and a second tensioning element system, wherein the two tensioning element systems are preferably formed from a single tensioning element, and wherein the tensioning system is guided such that the first tensioning element system intersects in a first intersection area and that the second tensioning element system intersects in a second intersection area, wherein the first and / or the second intersection area lies / lie on the inside of the extremity when worn, and wherein preferably both ends of the tensioning element are connected to a tension control element. This extremity orthosis or bandage can be reversibly or irreversibly closed.

[0042] A preferred guidance of the tensioning element in an extremity orthosis according to the invention with only one tensioning element is as follows when worn: The tensioning element starts at its first end approximately at the level of the knee or elbow on the tension control element and extends upwards over the thigh or upper arm. The tensioning element then extends to one side of the extremity, in particular to the inner side of the extremity, where it is deflected upwards by the first coupling element of the first coupling system of the first tensioning element system. The tensioning element then extends again over the thigh or upper arm. The tensioning element then slides over the anterior region of the thigh or upper arm to the other side of the extremity, in particular the outer side of the extremity, and extends over the posterior side of the thigh or upper arm to the first side, in particular the inner side of the thigh or upper arm.There, the tensioning element is deflected downwards in the second coupling element of the first coupling system and continues towards the back of the thigh or upper arm. The tensioning element thus crosses the closed first coupling system twice. The tensioning element runs slightly diagonally downwards along the back of the thigh or upper arm to the second side, specifically the outer side of the extremity, and is guided vertically downwards under the joint, i.e., the knee or elbow, to the lower leg or forearm and thus to the second tensioning system. There, the tensioning element runs over the back of the lower leg or forearm to the first side, specifically the inner side of the lower leg or forearm. There, the tensioning element is deflected downwards in the second coupling element of the second coupling system of the second tensioning system and continues towards the back of the lower leg or forearm.The clamping element runs slightly diagonally along the posterior lower leg or forearm to the second side, specifically the outer side of the extremity, and is guided there towards the anterior lower leg or forearm and from there to the first side, specifically the inner side of the lower leg or forearm. There, the clamping element is deflected upwards by the first coupling element of the second coupling system of the second clamping element system, after which the clamping element runs again along the front of the lower leg or forearm and terminates at the tension control element with its second end. Both ends of the clamping element can thus be tensioned using the tension control element, for example, by coiling it up.

[0043] Preferably, the tension control element is located on the outside of the extremity, particularly if the coupling systems are located on the inside. Alternatively, the tension control element is located on the inside of the extremity, particularly if the coupling systems are located on the outside.

[0044] In a preferred embodiment, an extremity orthosis or bandage according to the invention comprises at least one hinged splint, preferably two hinged splints. Preferably, the two hinged splints are positioned laterally when worn, i.e., one on the outside of the extremity and one on the inside of the extremity. Preferably, the extremity orthosis or bandage has one hinged splint that is positioned on the outside of the extremity when worn. Alternatively, the extremity orthosis or bandage has one hinged splint that is positioned on the inside of the extremity when worn. When using two hinged splints, it is preferred that one of the two hinged splints, in particular the one positioned on the outside of the extremity, is connected to the tensioning element.Preferably, a second joint rail, in particular the joint rail on the inside of the extremity, is connected to one of the two coupling elements of the first clamping element and to one of the two coupling elements of the second clamping element.

[0045] Joint splints are usually designed so that knee movement can be adjusted not only in the sagittal plane but also in the frontal plane. In the frontal plane, these are adjustable hinge joints located as close as possible to the apex of the knee or elbow joint, thus relieving stress on the inner compartment of the femoris or elbow joint. The circularly arranged straps shown in the prior art act as counter-bearings above and below the knee joint on the opposite side of the joint splint. Such joint splints are known, for example, from WO 2007 / 145504 A1 or WO 2003 / 103547 A1.

[0046] In a preferred embodiment, the at least one articulated rail has a first rail section, a second rail section and a third rail section, wherein the first rail section and the second rail section are each connected to the third rail section by a joint.

[0047] In a preferred embodiment, the rail sections are elastically designed. In a preferred embodiment, the third rail section is formed from a spring element, in particular a leaf spring. The other two rail sections can also be formed from leaf springs.

[0048] In a preferred embodiment, the joints are monocentric. The two monocentric joints above and below the third, middle rail section of a jointed splint together form a duocentric mechanism, which advantageously results in less stress being generated in the knee joint during flexion. During flexion, the center of rotation can change multiple times from one pivot point to the other. In combination with elastic splints, particularly the leaf spring, the duocentric mechanism ensures that the orthosis or bandage does not shift laterally relative to the extremity axis, especially the leg axis, during flexion.

[0049] The design of the third rail section as a spring element, in particular a leaf spring, for example made of spring steel, results in the first and second rail sections not only rotating on one axis, but also being movable on an axis rotated by 90°, preferably in the area where the coupling element makes the central force application point of the three-point system created by the clamping system flexible. Furthermore, the two joints connecting the first and second rail sections, respectively, to the third rail section allow the articulated rail as such to adapt much better to the contours of the body.The spring mechanism of the third rail section also advantageously allows the orthosis or bandage for an extremity, especially a knee orthosis, to give way slightly during extreme movements, thus warning the user against excessively incorrect leg movement.

[0050] In a preferred embodiment, the connecting element is attached to the third rail section of the at least one hinged rail, in particular one of the two hinged rails.

[0051] In the case of an orthosis or bandage for extremities, in particular a knee orthosis or knee bandage, an additional support element may be present, for example a bandage base element, in particular a knitted or woven fabric, but the support element can also be dispensed with due to the design of the tensioning system according to the invention.

[0052] The extremity orthosis or bandage may additionally include a bandage base. Suitable bandage bases, in particular tubular bandage bases, are known to those skilled in the art. The bandage base is preferably not permanently connected to the rest of the extremity orthosis or bandage, but rather not connected at all or only reversibly. This allows the bandage base to be pulled over the extremity in the conventional manner, after which the rest of the extremity orthosis or bandage can be applied in the advantageous way described.In an alternative embodiment, the bandage base body can also be firmly and permanently connected to the rest of the extremity orthosis or bandage, for example, if the bandage base body can also be opened, for example by a zipper, a Velcro fastener or buttons, so that the bandage base body can also be placed around the extremity when putting it on and then closed, and the wearer does not have to put the extremity through the bandage base body.

[0053] Of course, it is also possible to forgo a bandage base, so that the limb orthosis or bandage is worn directly on the skin or over a garment. This allows the orthosis or bandage to be adapted to the patient's therapy progress.

[0054] Whether a given product is an orthosis or a bandage depends on whether the product has a bandage-like knitted or woven fabric and / or how heavily the product is equipped.

[0055] In a preferred embodiment, the extremity orthosis or bandage is a knee orthosis or bandage.

[0056] In a preferred embodiment, the limb orthosis is a knee orthosis. The ease of application and removal is particularly advantageous for a knee orthosis. However, these advantages also apply to an elbow orthosis, so the limb orthosis can also be an elbow orthosis.

[0057] In a preferred embodiment, the extremity bandage is a knee bandage. The ease of application and removal is particularly advantageous for a knee bandage. However, these advantages also apply to an elbow bandage, so the extremity bandage can also be an elbow bandage.

[0058] The extremity orthosis or bandage according to the invention can also be used as a sports aid. In an alternative embodiment, the extremity orthosis or bandage according to the invention is a sports aid.

[0059] When the present description refers to the position of an element of the orthosis or bandage in relation to a body part, this refers to the orthosis or bandage in the worn state, i.e., when the orthosis or bandage is applied to the extremity.

[0060] The invention is explained in more detail with reference to an example and the figures, which are not to be understood as limiting.

[0061] They show Figure 1 shows an extremity orthosis according to the invention as a knee orthosis; Figures 2 to 7 show different perspectives of the knee orthosis. Figure 1 Figures 8 to 11: Detailed views from the knee brace Figure 1 Figure 12 shows an extremity orthosis according to the invention as an elbow orthosis; Figure 13 shows the elbow orthosis made of Figure 12 Figure 14 shows an extremity orthosis according to the invention as an elbow orthosis with bandage; Figure 15 shows the elbow orthosis made of Figure 14 Figure 16 shows a preferred coupling device for an orthosis according to the invention in the closed state from the front; Figure 17 shows the coupling device made of Figure 16 in the closed position from the rear, Figure 18 the coupling device made of Figure 16 In the open position from the front, Figure 19 the coupling device made of Figure 16in the open position from the rear, Figure 20 the coupling device made of Figure 16 with instructions for use, Figure 21 Detailed views of the coupling device from Figure 16 .

[0062] Figure 1 Figure 1 shows an extremity orthosis according to the invention, specifically a knee orthosis (1000) on a leg (1500) comprising a thigh (1510), knee area (1520), and lower leg (1530). A bandage (500) is associated with the knee orthosis (1000). The knee orthosis includes a tensioning system (300) consisting of a Bowden cable (320) with a rope (323) largely concealed by a sheath (321). The Bowden cable (320) runs on padding (325). The first rope end (322) and the second rope end (324) are connected to a rotary knob (340) for tensioning.

[0063] In Figure 2 and Figure 3The knee orthosis (1000) is visible on the inner side (1501) of the leg. A second joint rail (420) runs along this side, comprising a first rail section (421) connected via a first joint (424) to a third rail section (423), and a second rail section (422) also connected via a joint (425) to the third rail section (423). Within the area of ​​the second joint rail (420) are two coupling devices (10), each consisting of a first coupling element (100) and a second coupling element (200). The two coupling devices (10) simultaneously fulfill two functions: firstly, to allow the knee orthosis (1000) to be opened and closed reversibly, and secondly, to redirect the Bowden cable (320) via a first guide (10) and a second guide (201).

[0064] Figure 4Figure 1 shows the knee orthosis (1000) on the back of the leg. It shows how the tensioning system (300) is divided into a first tensioning element system (301) on the thigh (1510) and a second tensioning element system (302) on the lower leg (1530), both of which are tensioned.

[0065] In Figure 5 and Figure 6The knee orthosis (1000) is shown on the outside (1502) of the leg. A first joint rail (410) runs along this side, comprising a first rail section (411) connected via a first joint (414) to a third rail section (413), and a second rail section (412) also connected via a joint (415) to the third rail section (413). A connecting and tensioning element, designed as a rotary knob (340), is located on the third rail section (413) for tensioning the Bowden cable (320). The first end (322) and the second end (324) of the cable (323) terminate at the rotary knob (340). The joint rail (410) also features rotatably mounted fastening elements (326) and rotatably mounted deflection guides (327) for the Bowden cable (320).

[0066] Figure 7 shows again how Figure 1the front of the leg (1500) with the knee orthosis (1000), where the division of the tensioning system (300) formed by the Bowden cable (320) into a first tensioning system (301) on the thigh (1510) and a second tensioning system (302) on the lower leg (1530) can again be seen, with the rotary knob (340) positioned as a tension control element in the knee area (1520).

[0067] The Figures 1 to 7 The figures clearly show the course of the Bowden cable (320) as a tensioning system (300) in the given order: The Bowden cable (320) as a tensioning element (300) starts with the first end (324) at approximately the level of the knee at the tension control element (340) on the outside of the leg and runs upwards over the thigh (1510) ( Figure 1). The tensioning element then extends to the inside (1501) of the leg and is deflected upwards there by a guide (101) in the first coupling element (100) of the first coupling system (10) of the first tensioning element system (301), whereupon the tensioning element again runs over the thigh ( Figure 2 The tensioning element (300) then slides over the front of the thigh to the outside of the thigh and runs over the back of the thigh to the inside of the thigh. There, the tensioning element (300) is deflected downwards by a guide (201) in the second coupling element (200) of the first coupling system (10) and guided further towards the back of the thigh ( Figure 3 The clamping element (300) crosses twice through the closed first coupling system (10). The clamping element (300) runs slightly diagonally downwards along the posterior thigh ( Figure 4) to the outside of the leg and is guided vertically downwards under the knee to the lower leg and thus to the second tensioning system (302) Figure 5 ). There, the clamping element (300) runs over the back of the lower leg to the inside of the lower leg ( Figure 4 ). There, the clamping element is deflected downwards by a guide (201) into the second coupling element (200) of the second coupling system (10) of the second clamping element system (302) and guided further towards the rear lower leg ( Figure 3 ). The tensioning element (300) runs along the back of the lower leg towards the outside of the leg ( Figure 5 ) and is directed there towards the front of the lower leg ( Figure 6 ) and from there further to the inside of the lower leg ( Figure 2). There, the clamping element (300) is deflected upwards by the deflection (101) of the first coupling element (100) of the second coupling system (10) of the second clamping element system (302), whereupon the clamping element (300) again runs over the front of the lower leg and ends with its second end (324) again at the tension control element (340) on the outside ( Figure 7 ). The tension control element (340) thus allows both ends (322,324) of the rope (323) of the Bowden cable (320) to be tensioned.

[0068] Figure 8 Figure 1 shows the cutout on the inner side (1501) of the thigh (1510). Visible is the upper coupling system with the first coupling element (100) with guide (101) for the Bowden cable (320) and the second coupling element (200) with guide (201) for the Bowden cable (320). The knitted bandage (500) is reversibly connected via a pocket to the upper, first rail section (421) of the second joint rail (420).

[0069] Figure 9 Figure 1 shows the cutout on the inside (1501) of the lower leg (1530). Visible is the lower coupling system with the first coupling element (100) with guide (101) for the Bowden cable (320) and the second coupling element (200) with guide (201) for the Bowden cable (320). The knitted bandage (500) can be reversibly connected via a pocket to the lower, second rail section (422) of the second joint rail (420).

[0070] Figure 10 shows the excerpt from Figure 8 the upper coupling system is open, thus separating the first coupling element (100) from the second coupling element. The first coupling element (100) is connected to the upper, first rail section (421) of the second articulated rail (420).

[0071] Figure 11 shows the closing process of the open knee brace Figure 10. The second coupling element (200) is guided to the first coupling element (100) and connected to it.

[0072] Figure 12 Figure 1 schematically shows an extremity orthosis according to the invention as an elbow orthosis (2000) on an arm (2500) with upper arm (2510), elbow region (2520) and forearm (2530). A bandage can be associated with the elbow orthosis (2000). The elbow orthosis comprises a tensioning system (300) with a rope (323). Figure 12 a) shows the outer arm Figure 12b The figure shows the inner arm. A joint splint (410) rests against the outer arm. The two coupling systems (10) for opening and closing the elbow orthosis (2000) are located on the inner arm. Details of the design can be seen from the knee orthosis (1000). Figures 1 to 7 to be taken over.

[0073] Figure 13 schematically shows the elbow orthosis (2000) with rope (323) and coupling systems (100) made of Figure 12From another perspective. The articulated rail (410) has a first rail section (411) which is connected to a third rail section (413) via a first joint (414) and a second rail section (412) which is also connected to the third rail section (413) via a joint (415). A tension control element (not shown) is located on the third rail section (413).

[0074] Figure 14a, Figure 14b and Figure 15 shows another embodiment of the elbow orthosis (2000) with coupling systems (100) and joint rail (410) from the Figure 12 and 13 , in which a bandage (500) is assigned to the elbow orthosis (2000). The structure otherwise corresponds to that of the Figure 12 and 13 .
