Description

Technical Field

[0001] This utility model relates to the field of braces for correcting X-shaped and O-shaped legs, specifically a three-point support leg correction brace. Background Technology

[0002] X-shaped legs and O-shaped legs actually refer to genu valgum (knock-knees) and genu varum (knock-knees), respectively. Genu valgum means that when the knees are together, the ankles cannot be brought together, while genu varum means that when the ankles are together, the knees cannot be brought together. Whether it's X-shaped or O-shaped legs, the choice between conservative and surgical treatment should be based on the severity of the deformity. Conservative treatment mainly involves physical therapy and wearing orthotic braces to correct the deformity. Surgical treatment primarily involves osteotomy to correct the deformity.

[0003] Patent CN2023106066251, issued by Xinjiang Huaruitai Medical Technology Co., Ltd., discloses an O-leg correction device, such as... Figure 1 As shown, its structure includes an L-shaped support rod, a leg fixing structure, and a foot support structure. The L-shaped support rod includes an upright section and a horizontal section. The leg fixing structure is fixedly installed on the upper part of the upright section. The foot support structure includes a foot placement plate installed above the horizontal section and a foot fixing structure installed above the foot placement plate. The upright section includes a lower upright and an upper upright. The upper upright includes a vertical rod, a diagonal rod located below the vertical rod, and a connecting part located below the diagonal rod. The connecting part is hinged to the upper end of the lower upright. The vertical rod is located above the lower upright and close to... The invention relates to a foot support structure on one side; a support foot is located below the lower upright, extending forward and backward, and a first anti-slip pad is located below the support foot. This invention provides an O-leg correction device that can correct O-legs during exercise. Its innovation lies in its innovative design based on traditional strap-type corrective braces, utilizing the "lever principle" to increase the inward corrective force on the lower leg through a physical and mechanical structure. Over time, the lateral ligaments of the knee joint recover and shorten, while the medial ligaments lengthen and recover, thus correcting O-legs. However, this structure is too complex for young children, requiring long-term adult assistance. Often, both children and adults cannot maintain the corrective effect over time.

[0004] Patent CN2024106420999, Shaanxi Nuclear Industry 215 Hospital, an O-leg corrector such as Figure 2As shown, this design innovates upon previous airbag-based corrective braces. Its main feature is the linkage between an airbag-integrated resistance adjustment structure and a magnetic traction correction structure. The resistance adjustment structure differentiates different stages of O-leg correction based on the airbag's contraction. An indicator light illuminates the completion of each stage, signaling the start of the next. This gradual correction divides the O-leg correction process into stages, with each stage marked by an indicator light, allowing patients to see their progress and boosting their confidence. Furthermore, the phased approach allows for adjustments based on the progress at each stage, resulting in better outcomes. The addition of an electromagnetic coil utilizes electromagnetic induction. While the innovative concept is commendable, prolonged use by younger children, especially those in childhood or adolescence, can cause significant psychological stress and affect their concentration.

[0005] Therefore, there is a need in the market for a new type of orthodontic brace that is suitable for children and adolescents or younger children, reduces psychological stress during actual wear and correction, and can be worn and adjusted by themselves. Utility Model Content

A traction steel wire rope (2) is provided in the middle of the outer side for tightening the knob device (3). The 3D printed brace body (1) is tightened and fixed to the leg of the corrector by the cooperation of the upper and lower Velcro (4) and the triangular pull ring (5). A multi-adhesive self-adhesive layer is provided in the inner part of the 3D printed brace body (1) close to the skin. It is bonded and fixed by the multi-adhesive self-adhesive layer and the sweat-absorbing and moisture-wicking functional inner lining layer (7). In order to increase its cushioning and avoid wear, the four sides of the 3D printed brace body (1) are sealed by the edge sealing strip (6). The upper and lower ends of the 3D printed brace body (1) are provided with U-shaped clips (8) through which the traction steel wire rope can pass.

[0010] Preferably, the inner knee joint is provided with two upper and lower traction wire rope fixing ends A, which are composed of wire rope locks (10) and eyelet rivets (11) to fix the wire rope.

[0011] Preferably, the tensioning knob device (3) includes a winding wheel (31), a base (32), and a knob cover (33). The steel wire traction rope (2) is threaded on the winding wheel (31). When the knob cover (33) rotates, the traction steel wire rope (2) winds around the winding wheel (31), causing the traction steel wire rope (2) to be tensioned and generating a huge mechanical force through the gear structure on the device base (32). Therefore, a huge tension force can be generated with a very small force. The base (32) is fixed to the 3D printed support body (1) by a clamping screw (9).

[0012] Preferably, the tension knob device (3) is a device that locks in the forward direction and releases the rope in the reverse direction. The tension knob device (3) forms a three-point interaction support force with the upper and lower fixed ends A of the traction wire rope (2).

[0013] Preferably, in order to realize the torque sensing of the tension belt, a torque meter is provided between the winding wheel (31) and the knob cover (33), and an LED torque display screen is provided on the knob cover (33).

[0014] Preferably, the 3D printed support body (1) is provided with multiple ventilation holes.

[0015] Preferably, the Velcro (4) is fastened and fixed by pulling the triangular pull rings (5) together.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a three-point support leg corrective brace, which has the following beneficial effects:

[0018] This 3D-printed brace is printed according to the actual dimensions of the wearer to achieve customized knee valgus and varus correction angles. Compared with previous products on the market, it has a particularly good fit and comfort. The structure is integrally molded without any other additional structural designs. The tension knob device is a telescopic device that tightens in the forward direction and releases in the reverse direction. The tension knob device forms a three-point interaction support force through the traction steel wire rope and the two traction steel wire ropes set at the top and bottom. The three points are on the same plane but not on the same straight line. When the force direction of one point is opposite to that of the other two points, the interaction of the three forces produces a corrective effect according to the action and reaction forces, the law of force decomposition, and the lever balance principle, while reducing the wearing pressure of the wearer.
