Detailed Implementation

[0028] like Figures 1-3 As shown, the present invention provides an orthosis for the ankle and hip joints, comprising: a foot and ankle fixation member 100 and a support member 200; wherein, the foot and ankle fixation member 100 includes a foot wrapping part 110 and an ankle wrapping part 120, for fixing the ankle joint in a relatively stable posture; the support member 200 is detachably fixed to the inner side and / or outer side of the foot wrapping part 110, and the support member 200 abuts against the bed surface.

[0029] Compared with the prior art, the orthosis for the ankle and hip joints provided by this utility model stabilizes the ankle joint at a normal angle through the ankle fixation member 100. The support member 200 is connected to the side of the foot wrapping part 110 of the ankle fixation member 100. The support part 210 rests against the bed surface, and the supporting force of the support part 210 is transmitted to the torsional force through the leg, which can correct the internal and external rotation of the hip joint. If correcting the internal rotation of the hip joint, the support member 200 is connected to the inner side of the foot wrapping part 110, which applies an outward force to the hip joint. If correcting the external rotation of the hip joint, the support member 200 is connected to the outer side of the foot wrapping part 110, which applies an inward force to the hip joint. Of course, the support member 200 can be connected to both the inner and outer sides of the foot wrapping part 110, which can also prevent the internal and external rotation of the hip joint.

[0030] In one embodiment, such as Figure 2 andFigure 3 As shown, the inner and / or outer sides of the foot wrapping part 110 are provided with slots 111. The support member 200 includes a support part 210 and a U-shaped clip 220 located at one end of the support part 210. A clip 221 is provided on the inner side of the U-shaped clip 220. The U-shaped clip 220 is clamped to the side of the foot wrapping part 110, and the clip 221 is embedded in the slot 111. In use, place the U-shaped clip 220 against the side of the foot wrap 110 with the slot 111, and push the support 200 to make the U-shaped clip 220 open elastically, so that the locking block 221 is inserted into the slot 111. The U-shaped clip 220 returns to its original position, completing the assembly of the support 200. When it is necessary to remove or move to the other side of the foot wrap 110, flip the support 200 to the side without the locking block 221 to make the U-shaped clip 220 open elastically, and the locking block 221 disengages from the slot 111, completing the separation of the support 200 from the foot wrap 110. Repeat the above installation process to complete the assembly of the support 200, which can quickly install and remove the support 200 and has a relatively sturdy structure.

[0031] In one embodiment, the slot 111 is rectangular in shape, and the corresponding block 221 is rectangular in shape. Thus, the mating surfaces of the rectangular structures have right angles, which can improve the fit and reduce the offset between the support 200 and the foot wrap 110, which is beneficial for hip joint correction.

[0032] In one embodiment, the inner width of the U-shaped clip 220 is 0.1-2 mm smaller than the side thickness of the foot wrapping part 110. In this way, the U-shaped clip 220 has a certain clamping force on the foot wrapping part 110, which can improve the connection stability between the support member 200 and the foot wrapping part 110.

[0033] In one embodiment, such as Figure 3 As shown, the support 210 includes an upright section 211 and a movable leg 212. A limiting groove 213 is formed on the bottom side of the upright section 211. The movable leg 212 has a protrusion 214 that extends into the limiting groove 213. The protrusion 214 is connected to the upright section 211 by fasteners. The limiting groove 213 is used to limit the minimum adjustment angle of the movable leg 212. It can be understood that by adjusting the angle of the movable leg 212 using fasteners, the overall length and support point of the support member 200 can be changed, thereby changing the support angle of the support member 200 to meet the needs of different users and adjust the correction intensity.

[0034] In one embodiment, the fastener includes a fastening bolt 215 passing through the upright section 211 and the protrusion 214, and a nut 216 screwed to the fastening bolt 215. Thus, by loosening or tightening the nut 216, the movable leg 212 can be in an angle-adjustable state or a fixed state.

[0035] In one embodiment, the ankle wrap 120 includes a front half-wrap plate 121 and a BOA lacing system 122 for easy and quick wear.

[0036] In one embodiment, the front half-enclosing plate 121 and the foot wrapping part 110 are integrally formed. Specifically, the front half-enclosing plate 121 and the foot wrapping part 110 are made of PVC, PC or polyurethane by injection molding process, with a Mohs hardness of 50-90, which has sufficient mechanical strength and elasticity, and is not easy to deform significantly during correction, while not being too hard to cause discomfort to the user.

[0037] In another embodiment, such as Figures 4-6 As shown, the inner and / or outer sides of the foot wrap 110 are provided with at least two positioning holes 112, and one end of the support member 200 is provided with at least two screw holes 222 corresponding to the positioning holes 112. The wrap is provided with at least two screws 113 that pass through the positioning holes 112 and are screwed into the screw holes 222. In use, the support member 200 is connected to the side of the foot wrap 110 by the two screws 113, which can also be used for quick assembly and disassembly of the support member 200 and for changing the side of the support member 200.

[0038] In one embodiment, the support member 200 has an L-shaped structure. This provides the support member 200 with a larger bottom surface support, which helps to improve stability during correction.
