[0002] Orthopedics is one of the most common departments in major hospitals. Orthopedics, also known as orthopedic surgery, is a specialty or discipline in medicine that specializes in the anatomy, physiology and pathology of the skeletal muscle system, and uses drugs, surgery and physical methods to maintain and develop the normal form and function of this system, as well as to treat injuries and diseases of this system. We often find that when patients undergo orthopedic foot surgery, the force and reaction forces will cause redness, swelling, blisters and infection in the force-generating parts, which will cause pain to the patients and trouble to the doctors. Among them, an orthopedic foot orthosis with application number "CN202022916146.4" is used in this utility model. The folding component is set to drive the fixing plate to unfold or fold, which is convenient for fixing the corrective shoe, improves the correction effect on the foot, prevents the human foot from shaking and causing secondary injuries, and effectively reduces the volume of the corrective shoe. The fixed component is set to fix the fixing plate through the cooperation of the moving block, spring, fixing frame and U-shaped card block, which is more practical and makes the fixing plate more stable when unfolded. However, the foot orthosis still has certain shortcomings when in use: the connection between the sole and the upper of the orthosis is fixed and the height cannot be adjusted. When in use, the upper part cannot be adjusted in height according to the patient's leg length, thereby affecting the patient's comfort when wearing it. Utility Model Content

[0022] See also Figure 1-Figure 4 A height-adjustable foot orthosis comprises: a support sole 1, an adjustment mechanism 4 and a fixing mechanism 5; the support sole 1, the root of the support sole 1 is fixedly connected with an ankle wrapping piece 2, and the top of the ankle wrapping piece 2 is connected with a leg wrapping piece 3;

[0023] See also Figure 3 , the adjustment mechanism 4 includes a mounting sleeve 41 fixedly mounted on the outer wall of the ankle wrap 2, a rack 42 is slidably mounted inside the mounting sleeve 41, a mounting box 43 is mounted on the surface of the mounting sleeve 41, an adjustment knob 44 is rotatably mounted on the surface of the mounting box 43, a gear 45 is fixedly mounted on the middle part of the adjustment knob 44, the gear 45 is inserted through the mounting sleeve 41 and meshed with the rack 42, the top of the rack 42 is fixedly connected to the outer wall of the leg wrap 3, a limiting groove 46 is provided inside the mounting sleeve 41, limiting strips 47 are connected to both sides of the rack 42, the limiting strips 47 slide inside the limiting groove 46, and limiting teeth 48 are connected to both ends of the rack 42.

[0024] During specific use: turning the adjustment knob 44 drives the gear 45 to rotate inside the installation box 43, and the rotation of the gear 45 drives the meshingly connected rack 42 to perform lifting and lowering adjustment inside the installation sleeve 41. The lifting and lowering of the rack 42 drives the leg wrap 3 to follow the lifting and lowering, so that the leg wrap 3 can be adjusted in height relative to the ankle wrap 2, which is convenient for patients with different leg lengths to adjust the height when used. When the rack 42 is lifted and lowered, the limit strips 47 on both sides slide in the limit grooves 46 opened inside the installation sleeve 41, so that the rack 42 can be lifted and lowered stably. The two ends of the rack 42 are connected to the limit teeth 48. The limit teeth 48 limit the range of the lifting and lowering movement of the rack 42 to prevent the rack 42 and the gear 45 from slipping.

[0025] See also Figure 4 The fixing mechanism 5 includes a fixing belt 51 fixed on one side of the supporting sole 1 and the leg wrapping piece 3, and a connecting buckle 52 is fixedly connected to the other side of the supporting sole 1 and the leg wrapping piece 3. One end of the fixing belt 51 is inserted through the connecting buckle 52 and then folded back and magically bonded to itself. A protective pad 6 is slidably connected to the surface of the fixing belt 51, and the protective pad 6 is a sponge pad.

[0026] Specific use: When performing orthopedics, place the foot on the support sole 1, wrap the heel with the ankle wrap 2, fit the leg with the leg wrap 3, pull the fixing strap 51 so that the pad 6 on the surface of the fixing strap 51 contacts the leg and the instep, pass one end of the fixing strap 51 through the connecting buckle 52 and fold it back, and adhere the fixing strap 51 to itself with Velcro so that the orthotic device is fixedly worn on the foot. The pad 6 is made of sponge pad to improve wearing comfort and avoid pressure sores and marks on the skin.

[0027] See also Figure 3 The bottom of the leg wrapping piece 3 is fixedly connected with a guide rod 7, and the guide rod 7 is inserted and connected to the top of the ankle wrapping piece 2.

[0028] During specific use: the bottom of the leg wrapping piece 3 is fixedly connected with a guide rod 7. When the leg wrapping piece 3 is raised or lowered under the drive of the rack 42, the guide rod 7 slides inside the ankle wrapping piece 2, so that the leg wrapping piece 3 maintains a stable rise and fall.

[0029] See also Figure 3 A thread groove is formed at one end of the adjusting knob 44, and a fixing nut 8 is threadedly connected to the surface of the thread groove.

[0030] During specific use: a threaded groove is provided at one end of the adjusting knob 44, and a fixing nut 8 is threadedly connected to the surface of the threaded groove. When the adjusting knob 44 drives the gear 45 to rotate for adjustment, the fixing nut 8 is tightened to keep the adjusting knob 44 fixed to prevent the gear 45 from rotating after being driven by the rack 42.

[0031] When it is necessary to adjust the height of the leg wrap 3, turn the adjustment knob 44 to drive the middle gear 45 to rotate inside the installation box 43. The rotation of the gear 45 drives the meshing rack 42 to be raised and lowered inside the installation sleeve 41. The lifting and lowering of the rack 42 drives the leg wrap 3 fixed on the top to follow the lifting and lowering, thereby increasing or decreasing the distance between the ankle wrap 2 and the leg wrap 3, which is convenient for height adjustment when used for patients with different leg lengths, so that the leg wrap 3 can support the patient's legs, which is convenient for improving the wearing comfort during foot correction.
