Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example

[0024] Please see Figure 1-4 An adjustable lower limb fixation orthosis includes an orthotic base 1, straps 2, adjusting clips 3, guide sleeves 4, an orthotic extension frame 5, a rotating connecting piece 6, a threaded rod 7, a screw handle 8, and a screw sleeve bracket 9. Multiple sets of straps 2 are connected to the front two ends of the orthotic base 1. Each set of straps 2 has an adjusting clip 3 in the middle. A guide sleeve 4 is vertically arranged inside the orthotic base 1. The inner side of the guide sleeve 4 is vertically slidably connected to the outer side of the orthotic extension frame 5. The upper-middle rear side of the orthotic extension frame 5 is connected to the front side of the rotating connecting piece 6. The bottom end of the rotating connecting piece 6 is rotatably connected to the top end of the threaded rod 7. The bottom end of the threaded rod 7 is connected to the middle of the top end of the screw handle 8. The upper rear part of the orthotic base frame 1 is connected to the front side of the threaded sleeve frame 9. The inner wall of the threaded sleeve frame 9 is screwed to the outer wall of the threaded rod 7. An anti-rotation mechanism is also provided between the rotating connecting piece 6 and the threaded rod 7. When in use, the orthotic base frame 1 is wrapped around the outside of the patient's affected limb, and is wrapped together by multiple sets of straps 2. It is adjusted and fixed by the adjusting clip 3. Then, as needed, the threaded rod 7 is rotated under the constraint of the rotating connecting piece 6 by turning the handle 8. The threaded rod 7 is screwed to the threaded sleeve frame 9 and is connected to the orthotic extension frame 5 by the rotating connecting piece 6. It slides vertically under the constraint of the guide sleeve 4, moving out the corresponding length to meet the correction needs of the affected limb, and is fixed by the anti-rotation mechanism.

[0025] The anti-rotation mechanism includes a chuck 10, a connecting plate 11, a spring 12, and a top support plate 13. The upper outer side of the threaded rod 7 is connected to the inner side of the chuck 10. After rotating the connecting plate 6, the middle side is connected to the top of the connecting plate 11. The front end of the connecting plate 11 is connected to the rear side of the top support plate 13 via the spring 12. With the connection of the connecting plate 11, the top support plate 13 can be clamped on the outer side of the chuck 10 by the supporting action of the spring 12, preventing the threaded rod 7 from rotating and improving stability.

[0026] It also includes a sliding sleeve 14, a sliding rod 15, and a pull tab 16. The lower inner side of the connecting piece 11 is connected to the outer side of the sliding sleeve 14. The inner wall of the sliding sleeve 14 is slidably connected to the outer wall of the sliding rod 15. The rear end of the sliding rod 15 is connected to the middle of the front end of the pull tab 16. The front end of the sliding rod 15 is connected to the middle of the rear end of the top support plate 13. By holding the pull tab 16, the sliding rod 15 can slide backward under the constraint of the sliding sleeve 14, thereby connecting the top support plate 13 to move backward and releasing the locking wheel 10, improving convenience.

[0027] It also includes slots 17, straps 18, adjustment clips 19, and limiting plates 20. Multiple sets of slots 17 are provided on the left and right sides of the orthopedic extension frame 5. Straps 18 pass through the inside of the slots 17. The outer side of each set of straps 18 is connected to the middle of the inner side of a set of limiting plates 20. Adjustment clips 19 are provided on the inner side of the two sets of straps 18. After the orthopedic extension frame 5 extends outward, the straps 18 can pass through the slots 17, be limited by the outer side of the limiting plates 20, and can be adjusted by the adjustment clips 19 to improve practicality.

[0028] It also includes a pad 21, with the rear side of each set of adjustment card 1 3 and adjustment card 2 19 connected to the inner side of a set of pads 21 respectively; the pads 21 allow the lower limbs of the corresponding adjustment card 1 3 and adjustment card 2 19 to make contact with each other, avoiding injury and improving comfort.

[0029] It also includes an information board 22, with the lower left side of the orthopedic base 1 connected to the inner side of the information board 22; the information board 22 can display information about the device, making it easier to read and use, and improving convenience.

[0030] In summary, when using an adjustable lower limb fixation orthosis, the orthotic base 1 is wrapped around the outside of the patient's affected limb by multiple sets of straps 2, and then adjusted and fixed by the adjusting clip 3. As needed, by holding the pull tab 16, the sliding rod 15 can slide backward under the constraint of the sliding sleeve 14, thereby loosening the pull tab 10 and connecting the top support plate 13. By turning the handle 8, the threaded rod 7 rotates under the constraint of the rotating connecting piece 6. The threaded rod 7 is screwed into the threaded sleeve frame 9, and the orthotic extension frame 5, connected by the rotating connecting piece 6, slides vertically under the constraint of the guide sleeve 4. The device extends to the appropriate length to meet the correction needs of the affected limb. Under the connection of the connecting piece 11, the spring 12 provides support, which allows the top support plate 13 to be locked on the outside of the locking wheel 10, preventing the threaded rod 7 from rotating. After the orthotic extension frame 5 extends outward, the second strap 18 can pass through the through slot 17 and be limited by the outside of the limiting piece 20. The binding can be adjusted by the second adjusting card 19, and the pad 21 allows for the corresponding adjustment of the lower limb external contact between the first adjusting card 3 and the second adjusting card 19 to avoid injury. The information plate 22 displays the information of this device, making it easy to read and use, and improving convenience.

[0031] This adjustment card 3 is a device known to those skilled in the art and can be purchased directly from the market. Here we are simply using it without making any structural or functional improvements, and we will not go into detail about it here.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
