The front of both the leg bandage 2 and the orthotic brace body 1 is an open structure, which is simple to wear, lightweight, and will not affect the child's normal life. At the same time, it will not affect the child's lower limb development, and it avoids the trouble of needing to change the cast multiple times, thus saving medical resources.

[0031] It also includes a perforated hole 7, which is opened in the heel part of the corrective brace body 1, thereby reducing the anterior displacement stress of the calcaneus and the plantar flexion stress of the hind foot.

[0032] The fixing unit 6 includes a strap 61, perforations 62, and ear loops 63. There are two sets of ear loops 63, which are symmetrically arranged on the front and rear sides of the opening of the orthotic body 1. The ear loops 63 are provided with perforations 62 spaced apart. The strap 61 passes through the perforations 62 on the two sets of ear loops 63 and binds and fixes the opening of the orthotic body 1. The strap 61 passes through the perforations 62 to bind the two sets of ear loops 63. The binding method of the strap 61 can be the same as the binding method of shoelaces, which adopts existing technology, so that the two sets of ear loops 63 are close to each other, thereby fixing the opening of the orthotic body 1, which facilitates the subsequent fixation of the ankle joint Velcro strap.

[0033] The ankle joint Velcro fixation set 8 includes two sets of ankle joint Velcro straps. The ends of both sets of ankle joint Velcro straps are connected and fixed to the side of the orthotic body 1. One set of ankle joint Velcro straps is placed at the fifth metatarsophalangeal joint of the affected foot, and the other set of ankle joint Velcro straps is placed at the first metatarsophalangeal joint of the affected foot. The two sets of ankle joint Velcro straps cross and cover the dorsum of the affected foot and are glued and fixed to the ankle joint of the child to correct foot deformity.

[0034] The sliding mechanism 3 includes a sliding sleeve 31 and a connecting strip 32. The end of the connecting strip 32 is fixedly connected to the side of the leg strap 2. Multiple sliding sleeves 31 are provided and are slidably arranged on the connecting strip 32. The thigh Velcro fastening group 4 and the calf Velcro fastening group 5 are arranged on the side of the corresponding sliding sleeve 31. By sliding the sliding sleeve 31 on the connecting strip 32, the position of the thigh Velcro fastening group 4 and the calf Velcro fastening group 5 can be adjusted to adapt to children of different body types.

[0035] The thigh Velcro fixation group 4 includes two sets of thigh Velcro straps, both of which are fixed to the side of the slide sleeve 31. The ends of the two sets of thigh Velcro straps are glued together to fix the child's thigh segment. The lower leg Velcro fixation group 5 includes two sets of lower leg Velcro straps, both of which are fixed to the side of the slide sleeve 31. The ends of the two sets of lower leg Velcro straps are glued together to fix the child's lower leg segment, ensuring the accuracy of the fixation.

[0036] The orthopedic brace body 1 is composed of a polyester fiber outer layer 101 and a pure cotton inner lining 102. The polyester fiber outer layer 101 can ensure the strength of the orthopedic brace body 1, and the pure cotton inner lining 102 is used to make soft contact with the child's skin.

[0037] The working principle of the ankle joint correction device for children with loose clubfoot provided by this utility model is as follows: The correction brace body 1 is composed of a polyester fiber outer layer 101 and a pure cotton inner lining 102. The polyester fiber outer layer 101 ensures the strength of the correction brace body 1, and the pure cotton inner lining 102 is used for flexible contact with the child's skin. It fixes the child's thigh segment through the thigh Velcro fixing group 4, fixes the child's lower leg segment through the calf Velcro fixing group 5, and presses the ankle joint Velcro fixing group 8 onto the dorsum of the child's foot and fixes the child's ankle joint position, thereby ensuring the accuracy of fixation. The front of the leg strap 2 has an open structure, thereby ensuring that the patella area is hollowed out, thereby reducing the movement of the patella. The corrective brace body 1 has a perforated hole 7 at the heel to reduce anterior calcaneal displacement stress and hindfoot plantar flexion stress. Two sets of ankle joint Velcro straps cross and cover the dorsum of the affected foot and are fixed to the ankle joint position of the child to correct foot deformity. When fixing the ankle joint, the strap 61 is first passed through the perforation 62 to tie the two sets of ear loops 63. The strap 61 can be tied in the same way as shoelaces, using existing technology, so that the two sets of ear loops 63 are brought closer to each other, thereby fixing the opening position of the corrective brace body 1. The position of the thigh Velcro fixing group 4 and the calf Velcro fixing group 5 can be adjusted by sliding the sliding sleeve 31 on the connecting strip 32 to adapt to children of different body types.
