[0028] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0029] It should be noted that, in the description of the present invention, unless otherwise specified, “multiple” means two or more; the terms “upper”, “lower”, “left”, “right”, “inside”, “outside”, “front end”, “rear end”, “head”, “tail”, etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0030] Furthermore, the terms "first," "second," "third," etc. are used for descriptive purposes only and are not to be understood as indicating or implying relative importance.

[0031] At the same time, in the description of this utility model, unless otherwise specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, it can mean fixed connection, detachable connection, or integral connection; it can be mechanical connection or electrical connection; it can be direct connection or indirect connection through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to the specific circumstances.

[0032] See Figure 1-6 This is an embodiment of a prosthetic orthosis of the utility model.

[0033] It includes a calf correction body 1, a thigh correction body 2 rotatably arranged above the calf correction body 1, and a height-increasing prosthesis 3 arranged at the lower end of the calf correction body 1;

[0034] When using this device, patients with leg atrophy caused by polio can place the atrophied and deformed legs in the calf correction body 1, and then fix the thigh correction body 2. This can correct the patient's legs. At the same time, one side of the leg of a polio patient will be shorter than the other normal leg due to atrophy, so this device is also equipped with a height-increasing prosthesis 3 to help patients achieve balance in both legs.

[0035] When in use, the tightening structure 4 can be opened, and the calf can be placed into the first cylindrical shell 11 through the first opening 12 on the front side of the calf correction body 1. At this time, since the foot plate 13 is integrally formed at the bottom of the first cylindrical shell 11, the foot plate 13 can provide support for the patient.

[0036] Then, a tightening structure 4 for tightening the first opening 12 is provided on the first cylindrical shell 11 and at the junction of the first cylindrical shell 11 and the foot plate 13; and then the first opening 12 is tightened by the tightening structure 4 to firmly bind the patient's legs.

[0037] After binding the calf, the thigh needs to be bound. Since the thigh corrector 2 for binding the thigh is arranged above the calf corrector 1, in order to prevent the thigh corrector 2 from affecting the wearing of the calf corrector 1, the thigh corrector 2 is rotated and arranged on the calf corrector 1. With this arrangement, when wearing the calf corrector 1, the thigh corrector 2 is rotated to the back first, which will not affect the wearing of the calf corrector 1.

[0038] Connecting rods 5 are provided on both sides of the first cylindrical shell 11. The upper ends of the connecting rods 5 are connected to mounting rods 8 via rotating components 7. The thigh correction body 2 is fixed between the mounting rods 8.

[0039] Specifically, a connecting rod 5, a rotating assembly 7 and a mounting rod 8 are provided between the calf correction body 1 and the thigh correction body 2;

[0040] The rotating assembly 7 includes two symmetrically arranged side plates 71 and a mounting plate 72 arranged between the side plates 71 . The connecting rod 5 is rotationally connected to the mounting plate 72 , and the mounting rod 8 is fixedly connected to the mounting plate 72 .

[0041] With such arrangement, the thigh correction body 2 can be rotated.

[0042] The rotating assembly 7 is further provided with a fixing block 73 , which is slidably sleeved on the outside of the mounting plate 72 .

[0043] At the same time, the knees of some patients cannot be bent actively, so the device is also equipped with a fixing block 73. After wearing, the fixing block 73 can be used to lock the rotating component 7 to prevent the rotating component 7 from driving the thigh correction body 2 to rotate.

[0044] The thigh correction body 2 comprises a second cylindrical shell 21 with a second opening 22 on the front side; and a tightening structure 4 is provided on the second cylindrical shell 21 to tighten the second opening 22 .

[0045] The thigh orthosis 2 of this device is worn in the same way as the calf orthosis 1.

[0046] The tightening structure 4 includes a buckle 41, and a tightening belt 42 is connected to the buckle 41 through a steel ring 43. One end of the tightening belt 42 is fixed to the first cylindrical shell 11 or the second cylindrical shell 21;

[0047] One side of the tightening belt 42 is provided with a Velcro; and a protective pad 44 is provided on the tightening belt 42 .

[0048] When the tightening structure 4 in this device is used, it is only necessary to pull the tightening belt 42, tighten the first opening 12 or the second opening 22, and then stick them together with Velcro. It is very convenient to use. At the same time, a protective pad 44 is also provided in this device to protect the legs.

[0049] The height-increasing prosthesis 3 includes a fake shoe 31 and a height-increasing column 32 . The height-increasing column 32 is rotatably mounted on the fake shoe 31 , and an elastic recovery structure 9 is disposed between the fake shoe 31 and the height-increasing column 32 .

[0050] The fake shoe 31 comprises a shoe body 311 and a flat plate 312 mounted on the shoe body 311. Two first hinge plates 313 are symmetrically mounted on the flat plate 312. The heightening column 32 is pivotally mounted on the first hinge plate 313 via a pivot. The elastic recovery structure 9 comprises a fixed plate 91 secured to the heightening column 32. A spring member 92 is hingedly connected between the fixed plate 91 and the flat plate 312. The spring member 92 comprises a spring 921 with connecting plates 922 mounted at each end. A hinged post 923 is mounted on the connecting plate 922. The hinged post 923 is pivotally mounted on a second hinge plate 924 located at the lower end of the fixed plate 91 and a third hinge plate 925 located at the upper end of the flat plate 312 via a pivot. Two elastic recovery structures 9 are symmetrically mounted at the front and rear ends of the heightening column 32.

[0051] In order to simulate the walking of a normal person, the height-increasing prosthesis 3 of this device has a height-increasing column 32 rotatably set on the artificial shoe 31, and is equipped with an elastic recovery structure 9 for controlling the rotation. In this way, the elastic recovery structure 9 is used to simulate human muscles, allowing the patient to walk normally.

[0052] When the height-enhancing column 32 rotates forward, the front spring member 92 will be compressed, and the spring 921 will accumulate elastic potential energy. At the same time, the rear spring member 92 will be stretched, and the spring 921 will also accumulate elastic potential energy, allowing the patient to walk in balance; when rotating backward, the front spring member 92 will be stretched, and the rear spring member 92 will be compressed, thereby simulating normal human walking.

[0053] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
