[0030] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0031] Reference Figure 1 and Figure 2 As shown, this utility model provides a technical solution: an ankle inversion corrector, including a support plate 1, a placement hole 2 on the upper surface of the support plate 1, the cross-section of the placement hole 2 being foot-shaped, an adjustment structure 3 on the upper surface of the support plate 1, and an auxiliary structure 4 on the upper surface of the support plate 1.

[0032] The specific settings and functions of its adjustment structure 3 and auxiliary structure 4 will be discussed below.

[0033] Reference Figure 3 and Figure 4As shown in this embodiment, the adjustment structure 3 includes a fixed base 301, a connecting plate 306, and two arc plates 308. The fixed base 301 is fixed to the upper surface of the bearing plate 1. A connecting plate 302 is rotatably connected to the inner wall of the fixed base 301. An arc-shaped hole 303 is provided on one side of the fixed base 301. The center of the arc-shaped hole 303 is coaxial with the axis of rotation of the connecting plate 302. A screw 304 is slidably connected to the inner wall of the arc-shaped hole 303. One end of the screw 304 is fixedly connected to one side of the connecting plate 302. A lead screw 307 is threaded through the side of the two arc plates 308. The arc surface of the lead screw 307 has a bidirectional thread. The lead screw 307 rotatably passes through the side of the connecting plate 306, and the connecting plate 302 slidably passes through the lower surface of the connecting plate 306. By setting the adjustment structure 3 and adjusting the arc plates 308, people with different leg lengths can use the ankle inversion corrector, thus improving the applicability of the ankle inversion corrector. A positioning plate 309 is fixedly connected to one side of the connecting plate 306. Positioning rods 310 slide through the sides of both arc plates 308, with the ends of the two positioning rods 310 fixedly connected to the sides of the positioning plate 309 respectively. When the lead screw 307 drives the arc plate 308 to move, the arc plate 308 moves along the arc surface of the positioning rods 310, thus preventing rotational deviation during its movement. Rubber pads 311 are fixedly connected to the inner walls of both arc plates 308, and the rubber pads 311 are adapted to the dimensions of the inner walls of the arc plates 308. The rubber pads 311 improve the softness of one side of the arc plate 308, thus preventing the arc plate 308 from pinching the patient's skin. An adjusting ring 305 is threadedly connected to the arc surface of the screw 304, and the adjusting ring 305 is fixedly connected to one side of the fixed seat 301. Rotating the adjusting ring 305 abuts against the fixed base 301, locking the connecting plate 302 and the arc plate 308. An arc-shaped rail 312 is fixedly connected to one side of the bearing plate 1. The center of the arc-shaped rail 312 is coaxial with the center of the arc-shaped hole 303. A sliding rod 313 is slidably connected to the inner wall of the arc-shaped rail 312. One end of the sliding rod 313 is fixedly connected to one side of the connecting plate 302. An elastic rope 314 is installed inside the arc-shaped rail 312, with both ends fixedly connected to the arc-shaped rail 312 and the sliding rod 313, respectively. The elastic rope 314 can pull the sliding rod 313 to automatically slide along the inner wall of the arc-shaped rail 312. The sliding rod 313 drives the connecting plate 302, which in turn drives the connecting plate 306 and the two arc plates 308. The arc plates 308 drive the patient's lower leg, thus enabling the foot to automatically push outward for resistance training of eversion.

[0034] Reference Figure 5 and Figure 6As shown in this embodiment: the auxiliary structure 4 includes two limiting rings 41, which are fixed to the upper surface of the support plate 1. A limiting band 42 passes through the inner wall of the two limiting rings 41. An adjusting rod 43 is threaded through the upper surface of the limiting rings 41, and a pressure plate 44 is rotatably connected to the lower end of the adjusting rod 43. A guide rod 45 slides through the upper surface of the limiting rings 41, and the lower end of the guide rod 45 is fixedly connected to the upper surface of the pressure plate 44. By setting the auxiliary structure 4, after the person's foot enters the placement hole 2, the limiting band 42 can be adjusted to tighten and limit the foot, thereby preventing the foot from falling out of the placement hole 2 and improving the stability of the ankle inversion corrector. A limiting groove 46 is opened on one side of the inner wall of the limiting ring 41, and the size of the limiting groove 46 is smaller than the size of the pressure plate 44. When the pressure plate 44 is used to press and limit the limiting band 42, the limiting band 42 can be squeezed into the limiting groove 46, which achieves the effect of fixing the limiting band 42 more securely.

[0035] Detailed Instructions for Use: When a patient with ankle inversion needs to use the orthosis for correction, first place the foot in the placement hole 2 on the support plate 1, then pull the connecting plate 306 to adjust its height. As the connecting plate 306 rises and falls, the connecting plate 302 moves through the lower surface of the connecting plate 306. After the connecting plate 306 drives the arc plate 308 to a suitable height, rotate the screw 307. The screw 307 drives the two arc plates 308, causing them to move towards each other simultaneously. Once the arc plate 308 and the rubber pad 311 are firmly in contact with the patient's lower leg, the ankle inversion orthosis is fixed. When the patient's ankle moves, the connecting plate 302 rotates along the inner wall of the fixing seat 301. Due to the presence of the arc hole 303 and the screw 304, the direction and angle of the patient's foot movement can be adjusted. The system effectively prevents inversion of the patient's ankle. The elastic rope 314 pulls the slide bar 313 to slide automatically along the inner wall of the arc-shaped rail 312. The slide bar 313 drives the connecting plate 302, which in turn drives the connecting plate 306 and two arc plates 308. The arc plates 308 drive the patient's lower leg, thus enabling the foot to automatically push outward for resistance training of eversion. While the lead screw 307 drives the arc plate 308 to move, the arc plate 308 moves along the arc surface of the positioning rod 310, thus preventing rotational deviation during the movement of the arc plate 308. In addition, the rubber pad 311 can increase the softness of one side of the arc plate 308, thus preventing the arc plate 308 from pinching the patient's skin. Finally, the rotating adjusting ring 305 abuts against the fixing seat 301 to lock the connecting plate 302 and the arc plate 308.

[0036] When it is necessary to prevent a person's feet from falling out of the placement hole 2, first move the limiting band 42 through the two limiting rings 41 in sequence. After the limiting band 42 is taut and binds the person's feet, rotate the adjusting rod 43 to drive the pressure plate 44. The pressure plate 44 moves towards the limiting band 42 in the limiting position of the guide rod 45. The pressure plate 44 will squeeze the limiting band 42. When the limiting band 42 is squeezed into the limiting groove 46, the limiting band 42 can be fixed. When the pressure plate 44 is used to squeeze and limit the limiting band 42, the limiting band 42 can be squeezed into the limiting groove 46, which achieves a more stable effect in fixing the limiting band 42.
