    The invention relates to an orthotic or prosthetic socket for a leg orthosis or leg prosthesis for weight relief of a leg joint, in particular a hip, knee and / or ankle. The invention also relates to a leg orthosis or leg prosthesis with such an orthotic or prosthetic socket and to a use of such an orthotic or prosthetic socket and a method for weight relief of a leg joint.
    In the prior art, leg orthoses for relieving a leg joint, in particular a knee joint or a hip joint are already known.
    DE 10 2013 208 165 A1 discloses a leg orthosis with a first holding part for receiving a thigh and a second holding part for receiving a lower leg. The holding parts are spaced apart in the region of the knee and connected to each other on the inside and outside of the leg via a respective narrow orthotic joint. The orthotic joints go into narrow slide rails, which are attached to the second holding part. In the slide rails a bracket is mounted, which is connected to an adjusting device. By means of the adjusting device, the distance between the first and second holding part can be increased to relieve the knee joint. For this purpose, the adjusting device on a gas spring, which in this case generates the thrust force acting on the first and second holding part.
    DE 20 2014 008 160 U1 discloses a hip joint relief orthosis having an upper thigh socket which engages around a thigh near the hip joint and a lower thigh socket which engages around the thigh near the knee joint. The upper and lower thigh recesses are spaced apart and connected to one another only on the inside and outside of the leg via an adjustment device for increasing the distance between the thigh cushions. The adjusting device is in each case formed on the inside of the leg and the outside of the leg as a rod-like cylinder-piston unit.
    A disadvantage of the two leg orthotic described above is that the holding parts on which the thrust acts, are widely spaced apart, whereby the orthoses have a lower stability transverse to the longitudinal direction of the orthosis and just offer a worse grip in the weight relief position. In addition, a two-part shaft with spaced apart holding parts due to multiple edges involves the risk of cutting into the tissue when the orthosis is firmly attached.
    It is therefore an object of the invention to provide an orthotic or prosthetic socket for a leg orthosis or prosthesis, which has a high stability and supportability in particular transversely to the longitudinal direction of the shaft and also offers a high level of comfort.
    According to the invention, a length-adjustable orthotic or prosthetic socket is provided for a leg orthosis or leg prosthesis for weight relief of a leg joint. The orthotic or prosthetic socket is at least partially substantially cylindrical jacket-shaped for receiving a thigh and has a first and a second shaft part, which are arranged in the direction of the cylinder axis, ie in the longitudinal direction of the orthotic or prosthesis shaft, overlapping, so that the first and the region of the second part of the shaft form a substantially continuous cylinder jacket surface. The first shaft part is designed for support on the seat leg and the second shaft part for support on the Fußbo-the and / or on the leg on a side remote from the seat leg of the leg joint.
    Furthermore, the length-adjustable orthotic or prosthesis shaft according to the invention has an adjusting device for telescoping the first and second shaft parts in the direction of the cylinder axis so that the orthosis or prosthesis shaft can be brought from a starting position into a joint relief position.
    A particularly preferred embodiment of the length-adjustable orthotic or prosthetic shaft according to the invention is characterized in that the first and the second shaft part form a substantially continuous and smooth surface on an inside of the orthotic or prosthetic shaft facing a thigh receiving area. By a contiguous surface is meant herein a surface which has no openings which are substantially perpendicular to the longitudinal direction of the orthotic or prosthetic shaft extending through holes. A contiguous surface on the inside of the orthotic or prosthetic shaft improves the stability and supportability of the leg orthosis or prosthetic leg transversely to its longitudinal direction. A smooth surface enhances the comfort of the leg orthosis or prosthesis by avoiding edges that could cut into the tissue.
    The first and / or the second shaft part may be designed to be open or closed in a plane perpendicular to the cylinder axis. The entire Orthe-sen- or prosthesis stem may be closed annularly in a plane perpendicular to the cylinder axis. Such a trained shaft provides a very good grip and high comfort, since there are no edges in the circumferential direction, where pressure points can arise.
    In a further advantageous embodiment of the invention, the adjusting device comprises a cable pulling device. Furthermore, the second shaft part can have a linear guide, in which the first shaft part can be guided in the direction of the cylinder axis. The cable pulling device can in particular comprise a cable fastened to the second shaft part and a tensioning lever for tensioning the cable and two deflecting rollers fixed to the first shaft part, over which the cable can be guided, so that the first shaft part in the linear guide is directed away from the second shaft part by tensioning the cable from the home position to the joint relief position is movable. The clamping lever can be latched to fix the joint relief position.
    It is particularly advantageous if the joint relief position corresponds to an extension of the orthotic or prosthesis stem relative to the starting position by 10 to 30 mm, preferably 10 to 20 mm, preferably 13 to 17 mm, particularly preferably 15 mm.
    In a further advantageous embodiment of the invention, the first shaft part in a contact area with the seat leg on removable padding pads for additional relief of the leg joints on.
    According to the invention, a leg orthosis or prosthesis for weight relief of a leg joint with a length-adjustable orthotic or prosthetic socket described above is also provided. The leg orthosis or prosthesis may have one or more orthotic or prosthetic joints. In particular, these orthotic or prosthetic joints may have a blocking function for stiffening the orthotic or prosthetic joint when a corresponding leg joint is to be relieved.
    The invention also includes a use of a previously described length-adjustable orthotic or prosthetic shaft for a Beinortenhe-se or prosthetic leg for weight relief of a hip, knee and / or ankle.
    The invention further includes a method for weight relief of a leg joint by means of a leg orthosis or leg prosthesis with a length-adjustable orthotic or prosthetic stem described above, wherein during a wearing time of the leg orthosis or leg prosthesis of the adjustable length Orthesen- or prosthesis stem, if necessary, intermittently or permanently in the joint relief position is brought.
    An embodiment of a length-adjustable orthotic or prosthetic shaft according to the invention is shown in the figures and will be explained in more detail with reference to these figures. In the figures described herein, identical or similar elements or features are designated by identical or similar reference numerals, so that their detailed description need not be repeated. The embodiment described below includes a variety of features and related advantageous features of the present invention. However, the features described in the context of the embodiment can each also represent an advantageous development of the invention.
    Show it:
    Figure 1 a length-adjustable orthotic or
    Prosthesis shaft in a side view,
    Figure 2 shows the orthotic or prosthesis stem of Figure 1 in a shortened
    Condition with open cocking lever and
    FIG. 3 shows the orthotic or prosthetic socket from FIG. 1 in the extended state with the clamping lever closed.
    FIG. 1 shows a length-adjustable orthotic or prosthetic socket 1 according to the invention for relieving a hip joint in a side view. The orthotic or prosthesis shaft 1 has a first shaft part 1 a and a second shaft part 1 b, which essentially have the shape of a hollow cylinder with an opening 14 open in the front. In an overlapping region 1c, the first shaft part 1a overlaps the second shaft part 1b, so that the first 1a and the second shaft part 1b form a substantially contiguous cylinder jacket surface which is open towards the front on an outer side 11 of the orthotic or prosthesis shaft 1. The first 1a and the second shaft part 1b are connected to one another along a longitudinal axis of the hollow-cylindrical orthotic or prosthesis shaft 1 displaceable by an adjusting device 2-8. In its region remote from the second shaft part 1 b, the first shaft part 1 a has a contact region 10 with the seat leg. This contact area 10 can be equipped with additional pads to increase the wearing comfort.
    The adjusting device 2-8 has a linear rail system 2, 5, 8, wherein a first rail 5 along the longitudinal axis (cylinder axis) is fixed to the first shaft part 1a and a second rail 2 is attached to the second shaft part 1b. In this case, the second rail 2 overlaps with the first rail 5 such that the first rail 5 can be guided in the second rail 2. In the upper region of the first rail 5 facing the contact region 10, a retaining rail 8 extending downwards, that is to say towards the second shaft part 1b, is fastened, which additionally guides the first rail 5 perpendicular to the cylinder jacket surface. In other words, the holding rail 8 holds the first rail 5 on the second rail 2 and thus holds the linear rail system together. At the top, a contact region 10 with the seat leg facing the end of the second rail 2 slightly to the rear, so offset to a side facing away from the opening 14 side of the second rail 2, a first guide roller 6 is fixed. A second deflection roller 7 is mounted centrally at an upper end of the support rail 8. The pulleys 6 and 7 are thus next to each other and offset from each other. The deflection rollers 6 and 7 together with a cable 4 a cable pulling device 4, 6, 7, with which the first 5 and the second rail 2 and thus the first and the second shaft part 1 b are mutually displaceable. The cable 4 is fixed at its upper end 13 at the upper end of the first rail 5 such that it extends from its fixed end 13 below the guide roller 7, from the guide roller 7 above the guide roller 6 and down to the second shaft part 1b. At its lower, a knee region 12 facing the end of the cable 4 with a clamping lever 3, approximately in the middle of the clamping lever 3, connected. The clamping lever 3 is also suspended at its upper end about a perpendicular to the cylinder axis and tangent to the cylinder surface of the orthotic or prosthesis shaft 1 extending axis rotatably mounted on the second shaft portion 1 b. By folding the clamping lever 3 against the outer side 11 of the orthotic or prosthesis shaft 1, the clamping lever 3 engages and is secured against self-opening.
    FIGS. 2 and 3 show the mode of operation of the length-adjustable orthotic or prosthetic socket 1 according to the invention. FIG. 2 shows the orthotic or prosthesis socket 1 in a state in which the tensioning lever 3 is opened, ie folded away from the outside 11. In this case, a rope portion between the clamping lever 3 and the first guide roller 6 is reduced, a rope share between the guide roller 6 and the guide roller 7 increases. As a result, the first shaft part 1a, which is fixedly connected to the second deflection roller 7 and the first rail 5, can move downwards so that the two shaft parts 1a, 1b overlap more strongly, so that the overlapping area 1c is enlarged. A length of the orthotic or prosthesis shaft 1 is shortened.
    FIG. 3 shows the orthotic or prosthetic socket 1 from FIG. 1 in a state in which the tensioning lever 3 is closed. The clamping lever 3 is folded over a vertex out against the outside of the second shaft part, whereby the clamping lever 3 engages. The rope portion located between the first deflection roller 6 and the tensioning lever 3 is extended relative to the opened state, whereas the rope portion located between the deflection rollers 6 and 7 is shortened. As a result, the first shaft part 1a is pulled up, whereby the shaft parts 1a and 1b overlap less, so that the overlapping area 1c is reduced. The length of the orthotic or prosthesis shaft 1 is extended. The orthosis or prosthesis stem 1 is supported on the floor or on the leg on one of them
    From the side of the hip joint facing away from the seatbone, the extended orthotic or prosthetic socket 1 relieves strain on the hip joint.
