    Joint for knee joint orthoses, prostheses or supports
    The invention relates to a joint for knee joint orthoses, prostheses or supports, with at least one lower leg associated first joint leg and at least one thigh associated second joint leg, which are so overlappingly connected at their ends, that with increasing angle between the joint legs a combined rolling and sliding movement is effected in the plane defined by the two joint legs, wherein in the overlapping end of a joint leg curves are provided and at the overlapping end of the other joint leg with the curves of the other joint leg cooperating guide elements are provided.
    The terms "rotate", "roles", and "glide" are interpreted differently in connection with the movements taking place in a knee joint. In the technical sense, a rotary movement is usually the rotation of a body about a fixed axis. A rolling motion is technically comparable to a wheel rolling on a flat surface with the center of the wheel shifting in the direction of the rolling motion. Sliding motion is, in a technical sense, the displacement of a body relative to another body or its base, comparable to a blocking wheel being pushed on a flat surface (e.g., skid mark).
    A simultaneous rolling and sliding movement as it occurs in the knee joint is in this sense comparable to a wheel which rolls on a flat surface, but the center of rotation shifts in the direction of movement by a smaller or higher value than mathematically correspond to the rolling motion would (analogous to the spinning or blocking the wheels of a vehicle).
    The object of the present invention was a joint of the type specified, which optimally simulates the kinematics of the natural human knee by a variable rotation center.
    To solve this problem, the invention is characterized in that the curves are configured such that with increasing angle between the joint legs a combined rolling and sliding movement of the second joint leg is effected in the plane defined by the two joint legs in a direction which substantially radially to the axis of the first hinge leg leads into the enclosed between the two joint legs quadrant, the fulcrum of the two joint legs for an angle between the joint legs between 0 and 25 ° remains substantially stationary.
    According to a first embodiment of the invention, it is provided that a first curve as a substantially straight slot and a second curve around the slot as
    WY-3413 AT
    Center curved in the first joint leg is worked out, wherein the displacement of the guide element in the second curve with increasing angle causes a preferably progressive displacement of the other guide element in the slot.
    Advantageously, two curves in slot shape are worked out in one of the joint legs, the relative course with increasing angle between the joint legs causes a displacement of the second hinge leg substantially radially to the axis of the first hinge leg in the enclosed between the two joint leg circle segment, the two curves preferably curved and facing each other with their concave sides.
    Another embodiment of the invention, however, is characterized in that one of the joint legs has a hollow body, in which the other joint leg protrudes, wherein the inner surface of the hollow body has at least two curves, against which at least two cam-shaped outer contours of the other joint leg as guide elements.
    In order to allow an adaptation to the respective varus or valgus position of the knee, as well as a recording of the lateral movements as well as possibly a correction of pathological misalignments, an embodiment is provided in which at least one of the overlapping regions of at least one of the joint legs with the adjoining portion of the joint leg is connected via a monocentric joint whose axis is oriented substantially parallel to the plane defined by the angular movement of the two joint legs.
    If, according to a further optional feature of at least one of the overlapping regions, at least one of the joint limbs is connected to the adjoining section of the joint leg via two joint elements which provide rotational movement between the support body and the orthotic joint or joint of the knee joint support about the axis of the lower leg, the physiologically possible rotation of the lower leg about its longitudinal axis can take place when the knee is bent.
    A further optional feature provides that at least one of the overlapping regions of at least one of the joint legs is connected to the adjoining section of the joint leg via a length adjustment system which allows a change in distance between the section overlapping the other joint leg and the remaining part of the joint leg. The advantage of length adjustment is to reduce the stress exerted by the femoral condyles on the tibial plateau. ············································································································································
    To solve the task is also a knee orthosis with at least two lower leg associated first joint legs and at least two thighs associated second joint legs suitable, which are each connected via a joint according to one of the preceding paragraphs, wherein the two joints or the pivot points are at different heights to allow, for example, an adaptation to the respective varus or valgus position of the knee.
    In the following description, the invention will be explained in more detail by means of preferred but non-limiting embodiments and with reference to the accompanying drawings.
    1 to 4 each show different embodiments of a joint according to the invention in an exploded view.
    The main function of the joint according to the present invention is to simulate the kinematics of the human knee so as to obtain such a variable center of rotation when the joint is used in knee joint prostheses, orthoses or supports that no tension in the prosthesis or orthosis can arise. which are uncomfortable for the wearer or patient or impede the mobility of the leg.
    For this purpose, the joint comprises at least one first leg 1 associated with the lower leg and at least one second leg 2 associated with the thigh, which are connected in an overlapping manner by their ends. In the illustrated in Fig. 1 embodiment of the invention, two curves 3, 4 are worked out in the first joint leg. A first curve 3 is formed as a substantially straight slot, while a second, curved curve 4 is worked around the contactor 3 as a center around. At the second joint leg 2, two guide elements 5, 6 are provided, wherein in each case a guide element 5 or 6 engages in one of the curves 3 and 4 and therein along these curves 3, 4 is displaceable. In the course of the flexion movement of the two joint legs 1, 2 to each other, the guide element 6 engaging in the second curve 4 is guided according to the curvature of the curve 4, which movement of the guide element 6 along the curved path the pivot point of the two joint legs 1, 2 to an angle between the joint legs 1, 2 of 25 ° substantially stationary.
    In continuation of the flexion movement of the joint legs 1, 2 then causes the further preferably progressive movement of the Führungsseiementes 6 in the slot 4 and an increasing displacement of the other guide element 5 in the straight slot 3. The sole pivotal movement at stationary pivot is doing with increasing angle between the joint legs. 1 , 2 into a combined rolling and sliding movement in the plane defined by the two joint legs 1, 2, which preferably leads the center of rotation progressively substantially radially to the axis of the first joint leg 1 in the quadrants enclosed between the two joint limbs 1, 2.
    In a knee joint orthosis in each case two of the joints according to the invention are used, which may be either integral with extending along the upper or lower leg of the wearer longitudinal elements - see for example Fig. 3 - or as in the illustrated embodiments of FIG. 1, 2 and 4 can also be connected to the joint legs 1, 2 by, for example, screwing or riveting. The movement of the joint legs 1, 2 relative to each other is controlled by the interactive curves 3, 4 such that the joint leg 2 associated with the thigh relative to the lower leg associated joint leg 1 from anterior (viewed from the front side of the knee) to the rear (posterior ), in such a way that up to a flexion angle of the knee (flexion) of about 25 degrees predominantly a rotational movement without visible displacement of the center of rotation in the direction of posterior (back) takes place, which subsequently in a simultaneous rolling and sliding movement with a progressive horizontal displacement of the fulcrum between the two joint legs 1, 2 to the rear (posterior) passes. The diffraction angle of the joints according to the invention, which is formed until the end of the rotation, is preferably limited to approximately 120 degrees, but could also go to the maximum angle of diffraction of a knee of approximately 135 degrees.
    The guide elements 5, 6 can be designed as separate elements, as in FIG. 1, the guide element 6, which are connected by means of, for example screws 7 with the joint legs. But they can also be integrally formed with the joint legs 1, 2, as in the example shown in FIG. 1, the guide element 5 through which a screw 8 is guided, which connects a first cover 9 with a second cover 10 and so the joint holds together.
    After often a limitation of the mobility between the thigh and the lower leg of the wearer, in particular orthoses, is required, two pins 11 or similar elements are provided, which can be inserted through radial bores 12 in one of the joint legs 1, 2 and fixed therein depending on the placement of the pins 11, the movement of the guide element 6 in the slot 4, and thus the scope of the possible bending movement of the joint legs 1, 2 to each other, limited.
    Also, two curves in slot shape 13, 14, the embodiment of the joint according to the invention according to FIG. 3. Here, both long slots 13, 14 worked out in the joint leg 1 are curved around the pivot point of the joint legs 1, 2 as a region of curvature. In each slot 13,14 a bolt 15, 16 is guided as a guide element, which bolts 15, 16 are connected to the second hinge leg 2. In the course of rotation is through the arrangement and extending along the circumference
    WY-3413 AT changing curvature interactively causes the physiological rotational and progressive sliding movement of the two joint legs 1, 2 to each other, as already described above in connection with FIG.
    The two bolts 15, 16 preferably extend through the slots 13, 14 through to the opposite side of the hinge leg 1 and connect the second hinge leg 2 in turn with a cover plate 10, which holds the hinge legs 1 and 2 together. A friction-reducing intermediate plate 17 facilitates the relative movement of the two joint legs 1, 2.
    In order to allow a limitation of the scope of the possible bending movement of the joint legs 1, 2 to each other, is an array of holes 17, at least one pin (not shown) per joint leg 1, 2 and a nose-like projection la, 2a at each of the joint legs 1, 2 provided. The row of holes 27 extends in the joint leg 1 substantially parallel to the slot 13 and in Geienkschenkel 2 essentially mirror-inverted. If now in at least one of the holes 27, a pin is inserted, comes in the course of mutual movement of the joint legs 1, 2 relative to each other, the projection la, 2a to stop on this pin and thus blocks the further relative movement of the joint legs 1, 2. This effect can be achieved in at least two existing pins for both the flexion and the stretching movement. If even two pins are provided per joint leg 1, 2, the strength and thus the safety can be further increased. In the embodiment of Fig. 2 turn two guide curves are provided. These two guide curves 18, 19 together define a cavity 20, which is worked out in the joint leg 1. In this cavity 20 projects a cam-shaped guide body 21, which is guided in each case one of its two outermost sections on a respective guide curve 18,19. Furthermore, as a further curve, a slot 4 is curved around the cavity 20 as a center curved around. In this curved slot 4, a guide element 6 attached to the joint leg 2 is movably movable and displaceable therewith, in turn, and in combination with the action of the guide body 21 in the cavity 20, the above-described stationary and subsequently in the combined rolling and sliding motion movement to cause the fulcrum between the joint legs 1, 2.
    The cohesion of the joint of Fig. 2 is effected by two screws 7, which are screwed through the cover plate 10 into the guide body 21. The other side of the joint may again be protected by a cover plate 9. The arrangement of pins 11 and radial holes 12 for limiting the movement of the guide element 6 in the slot 4 thus also the limitation of the scope of the possible bending movement of the joint legs 1, 2 to each other can be provided.
    In the embodiment of Fig. 4, a cavity 22 in the joint leg 1 is worked out, which is limited by three guide curves 23, 24, 25. In this cavity 22 engages a triangular guide body 26 which is fixedly connected to the other joint leg 2 or formed thereon, by sliding along the three outermost regions of the guide body 26 along each one of the three guide curves 23, 24, 25, the physiological rotation and Sliding movement of the two joint legs 1, 2 to cause each other.
    Also, in the embodiment of Fig. 4, as in the case of the embodiment of Fig. 3, via an array of pins 11 and holes 27 limiting the movement of the guide body 26 in the cavity 22 thus limiting the scope of the possible bending movement of the joint legs 1, 2 to each other possible. However, the bores 27 are now shifted all the way to the outer edge of the joint leg 2 and to the edge of a cover plate 28 substantially corresponding to the joint leg 2 so that they actually represent notches in these components 2, 28 that are radially outwardly open.
