Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4The utility model provides a technical solution: a foot and ankle care tibiofibular joint reduction and fixation guide, comprising an ankle protector body and a reduction guide installed on one side of the ankle protector body, the ankle protector body comprising a wraparound jacket 1 and two groups of straps 2 arranged on the wraparound jacket 1, the two groups of straps 2 fix the wraparound jacket 1 by means of Velcro, a notch 3 is provided on the side of the wraparound jacket 1, the reduction guide is fixed in the notch 3, the reduction guide comprises an arc-shaped outer plate 4, a positioning plate 5, an adjuster 6 and a contact inner plate 7, the edge of the arc-shaped outer plate 4 is fixed to the inner wall of the notch 3 On the upper part, the position where the notch 3 is opened is the position of the distal tibiofibular joint. A group of guide grooves 8 and a group of positioning grooves 9 are opened on the surface of the arc-shaped outer plate 4. The positioning plate 5 is slidably set in the guide groove 8. A clamping rod 10 is fixed on one side of the positioning plate 5. The clamping rod 10 is located in the positioning groove 9. The adjuster 6 is composed of an outer plate 11, a screw 12 and an inner ball 13. The outer plate 11 is located on the outer side of the positioning plate 5 and the inner side is connected to the screw 12. The screw 12 is threadedly inserted into the outer plate 11 and the inner end is connected to the inner ball 13. The inner ball 13 is rotatably embedded in the contact inner plate 7, and the contact inner plate 7 is in contact with the distal tibiofibular joint.

[0022] Further improvement, such as Figure 1 As shown: the wrap-around jacket 1 comprises an outer shell 14 and an inner pad 15 arranged inside the outer shell 14. The outer shell 14 is made of thermoplastic plastic, and the inner pad 15 is made of breathable sponge material.

[0023] Further improvement, such as Figure 2 As shown, the guide groove 8 is longitudinally opened and two groups of blades 16 are symmetrically arranged inside. The two groups of blades 16 are made of rubber material and a gap groove 17 is formed between them to facilitate closing the guide groove 8.

[0024] Further improvement, such as Figure 2 As shown: a plurality of groups of limit openings 18 are evenly opened on the left side of the positioning groove 9 from top to bottom, and the upper and lower adjacent groups of limit openings 18 are equidistantly distributed, and the limit openings 18 are in a concave arc structure, and the clamping rod 10 is buckled in the limit opening 18. This design method facilitates the adjustment of the position of the positioning plate 5, and then adjusts the height of the adjuster 6 and the contact inner plate 7.

[0025] Further improvement, such as Figure 3 As shown: the contact inner plate 7 includes a plate body 19 and two groups of limiting side columns 20 built into the plate body 19. The plate body 19 is an arc-shaped structure and the inner wall is covered with Velcro 21. The two groups of limiting side columns 20 are symmetrically adhered to the Velcro 21. The position of the limiting side columns 20 can be adjusted according to the position of the patient's distal tibiofibular joint.
