[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0028] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying 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.

[0029] See also Figure 1-Figure 8 A pediatric foot and ankle orthosis brace, comprising a calf brace 100, an ankle brace 200, and a forefoot brace 300, wherein the calf brace 100 is provided with a plurality of first through holes 101, and the first through holes 101 are used to reduce the overall weight and make the part in contact with the calf more breathable;

[0030] The calf brace 100 is also provided with a hanging buckle 110, a fixing ring 120, and a first spherical portion 130. The hanging buckle 110 is used to pass through a rope or a strap, so as to pass around the calf through the strap to tie the calf brace 100 tightly to the calf;

[0031] The fixing ring 120 is arranged on the outer wall of the first spherical part 130, and a clamping groove 121 is formed between the fixing ring 120 and the outer wall of the first spherical part 130. The first spherical part 130 is a hemispherical shell, and the concave arc surface of the first spherical part 130 is used to cooperate with the heel (root bone);

[0032] The ankle brace 200 is provided with a second spherical portion 210 at a position corresponding to the first spherical portion 130. The second spherical portion 210 is inserted into the inserting groove 121, and the stud portion 411 of the lag screw 410 passes through the fixing ring 120, and its end surface clamps the second spherical portion 210 to the first spherical portion 130, thereby realizing the clamping assembly of the second spherical portion 210 and the first spherical portion 130, and the lag screw 410 and the fixing ring 120 are assembled and fixed by screwing together;

[0033] The ankle brace 200 is also provided with a slide groove 201, a fixing through hole 202, and a circular protrusion 220. The circular protrusion 220 is provided at the concave arc surface of the second spherical part 210 and is directly opposite to the pressing part of the square head screw 410. This design is to increase the strength of the second spherical part 210 on the one hand, and on the other hand, the contact surface of the circular protrusion 220 and the first spherical part 130 is set as a mutually fitting arc surface, which can greatly increase the friction force after the first spherical part 130 and the second spherical part 210 are clamped, thereby increasing the assembly strength between the first spherical part 130 and the second spherical part 210.

[0034] The first spherical part 130 and the second spherical part 210 form a sandwich spherical hinge mechanism. This design allows the ankle brace to rotate in three directions: sagittal axis, frontal axis and vertical axis, meeting the needs of correction in all directions. The square head design of the screw facilitates the doctor's rotation operation during correction. Loosen the square head screw, and the first spherical part can move up and down and forward and backward to align with the ankle rotation center of the child. Tighten the square head screw to fix the adjusted position;

[0035] The inner surface of the hemispherical structure of the ankle brace has a circular protrusion 220, the inner surface of the circular protrusion is concave and matches with the outer wall of the first spherical part, so as to facilitate the squeezing and fixing of the first spherical part when the square head screw is tightened;

[0036] The first spherical part is consistent with the ankle joint rotation center to ensure that the ankle brace will not interfere with each other when adjusting the angle, and will not cause additional displacement of the ankle joint;

[0037] The forefoot brace 300 is provided with a second through hole 301 that penetrates through the forefoot brace 300. The second through hole 301 provides ventilation function for the sole part when in use and reduces the weight of the forefoot brace. The forefoot brace 300 is also equipped with a first screw rod 510 and a second screw rod 520. The first screw rod 510 and the second screw rod 520 pass through the fixed through hole 202 and the slide groove 201 respectively. One end of the first screw rod 510 and the second screw rod 520 pass through the fixed through hole 202 and the slide groove 201 and are respectively assembled and fixed with the first nut 420 and the second nut 430 by screw thread engagement, so that the forefoot brace 300 is fixed on the ankle brace 200.

[0038] When in use, the forefoot brace 300 can rotate relative to the ankle brace 200 with the first screw 510 as the center, and the rotation angle is limited by the slide groove, so as to achieve the correction of the metatarsal relative to the heel. The forefoot brace is bound to the child's foot through a strap.

[0039] During actual manufacturing, a scanner is first used to obtain the external contours of the child's calf and foot. A three-dimensional model of the calf and foot is established through data processing based on the child's CT / MRI data. The calf brace and foot brace are designed based on the three-dimensional model. The final product is made through 3D printing technology, which can ensure that the entire brace is personalized with the child's calf and foot, thereby increasing the correction effect and user comfort.

[0040] The matters not described in detail in the present invention are all known technologies to those skilled in the art.

[0041] The preferred specific embodiments of the present invention are described in detail above. It should be understood that a person skilled in the art can make many modifications and changes based on the concept of the present invention without creative work. Therefore, any technical solution that can be obtained by a person skilled in the art through logical analysis, reasoning or limited experiments based on the concept of the present invention on the basis of the prior art should be within the scope of protection determined by the claims.
