AI Technical Summary
The connecting straps of existing foot and ankle orthotic braces are not adjustable, resulting in unstable fixation of smaller feet, which affects overall stability and applicability.
An orthotic brace for the foot and ankle was designed, comprising leg sleeves, foot sleeves, tension ropes, a retractable mechanism, and an adjustable strap. The adjustable strap is equipped with a limiting structure and a nylon hook and loop fastener structure, allowing the tension ropes to be adjusted as needed to adapt to different foot shapes, and the connection is strengthened by limiting protrusions and limiting holes.
It achieves a tight fit of the tension cord, adapts to different foot shapes, expands the range of applications, improves wearing comfort and stability, and simplifies the wearing and adjustment process.
