For example, patent number 202020150505.7 discloses a multifunctional ankle-foot orthosis, including a foot-shaped base plate and a tibialis base plate, which are vertically distributed and connected by two ankle joint connection mechanisms. Two parallel Velcro straps are fixedly connected to the inner bottom wall of the foot-shaped base plate, and a fan-shaped massage pad with the connection point of the plantar fascia and calcaneus as the axis is attached to the upper end of the two Velcro straps. The massage pad is connected to the position of the plantar fascia. Multiple soft massage hemispheres are evenly distributed on the upper end of the massage pad. A stretching mechanism corresponding to the abductor digitorum valgus muscle of the little toe is provided on the side wall of the foot-shaped base plate. This utility model can provide a certain massage effect on the plantar fascia and can perform flexion and stretching operations on the abductor digitorum valgus muscle of the little toe, relaxing the entire ankle and foot, reducing the tension of the entire ankle and foot, and improving the walking effect.

[0004] However, it cannot be adjusted slightly to allow for different needs and rehabilitation stages. The fixed angle can lead to insufficient pressure or support, thus limiting its effectiveness. Utility Model Content

[0023] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0024] A foot support device to prevent foot drop, such as Figure 1 As shown, the system includes a shin-shaped substrate 1 and a foot-shaped substrate 6. The shin-shaped substrate 1 has a Velcro strap 12 on its side, which is used to fix the Velcro strap 12 to the shin. The foot-shaped substrate 6 has a Velcro strap 61 on its side, which is used to fix the foot. Connecting plates 4 are fixed to both sides of the foot-shaped substrate 6, and a pointer 41 is provided at the top of each connecting plate 4. The connecting plates 4 are rotatably connected to the shin-shaped substrate 1, and a protractor 3 is provided on the side of the shin-shaped substrate 1. The pointer 41 is used to indicate the angle between the shin-shaped substrate 1 and the foot-shaped substrate 6. The foot-shaped substrate 6 and the two sides of the shin-shaped substrate 1 are connected by a traction assembly 2. The traction assembly 2 is a telescopic structure and is rotatably connected between the foot-shaped substrate 6 and the shin-shaped substrate 1.

[0025] For example, the traction component 2 can be a hook and loop fastener. The hook and loop fastener generally consists of a fastener (one side has a toothed barbed surface and the other side has a rough surface) and an adjustable snap fastener. One end of the fastener is fixed to the foot-shaped base plate 6, and the snap fastener is fixed to the shin-shaped base plate 1. The tightness is adjusted by passing the other end of the fastener through the snap fastener. This is the prior art. The hook and loop fasteners in this application all have this structure.

[0026] Preferably, the traction assembly 2 adopts the structure shown in the figure. Specifically, the traction assembly 2 includes a connecting piece 21, an inner rod 22, a locking screw 23, an outer rod 24, a connecting piece 25, and a fixing piece 26. The connecting piece 21 is rotatably connected to the side of the tibia-shaped base plate 1, and the connecting piece 25 is rotatably connected to the side of the foot-shaped base plate 6. The other end of the connecting piece 21 is rotatably connected to the inner rod 22, and the other end of the connecting piece 25 is rotatably connected to the outer rod 24. The inner rod 22 is inserted into the outer rod 24, the side of the outer rod 24 is threadedly connected to the locking screw 23, and the end of the locking screw 23 is rotatably connected to the fixing piece 26. Figure 2As shown, the outer surface of the inner insert rod 22 forms a groove, and the cross-section of the fixing piece 26 adopts a semi-circular annular structure; the inner wall of the fixing piece 26 forms a protrusion, which cooperates with the groove. The angle between the tibia-shaped base plate 1 and the foot-shaped base plate 6 can be adjusted according to the traction requirements. During adjustment, the locking screw 23 is rotated to loosen it, and then the inner insert rod 22 is moved until the traction assembly 2 reaches a suitable length. Then, the locking screw 23 is rotated in the opposite direction, causing the locking screw 23 to push the fixing piece 26 to grip the inner insert rod 22, thus achieving fixation in this state.

[0027] Furthermore, in order to increase overall breathability, the shin-shaped substrate 1 has multiple perforations 11 on its sidewall, and the foot-shaped substrate 6 has a rotating baffle 62 rotatably connected to its end. The rotating baffle 62 is used to block the toes and prevent toe dents during use.

[0028] Furthermore, the foot-shaped base plate 6 is provided with an auxiliary component 5 at its end. The auxiliary component 5 includes a first baffle 51 and a second baffle 52. The first baffle 51 and the second baffle 52 are rotatably connected to the side of the foot-shaped base plate 6 via a rotating shaft. There is damping between the first baffle 51, the second baffle 52 and the rotating shaft, so that the first baffle 51 and the second baffle 52 can be rotated 90° to be fixed. This allows the first baffle 51 and the second baffle 52 to be rotated open when the user is lying down. The first baffle 51 and the second baffle 52 can support the foot-shaped base plate 6 and keep the foot-shaped base plate 6 at the center position of the top of the two baffles.

[0029] During normal walking, foot pressure is concentrated in the heel, forefoot, and arch. However, foot drop patients may experience abnormally high pressure in certain areas (such as the heel or metatarsal heads) due to muscle atrophy, nerve damage, or prolonged immobilization, making them prone to pressure sores. To accommodate different degrees of foot deformity in different patients (such as high arches or flat feet), the support area needs to be adjusted accordingly. The foot-shaped base plate 6 has a foot pad 7 inside, which includes a mesh layer 71, a silicone pad layer 72, a rigid support plate 73, a soft pad 74, a support plate 75, an extension plate 76, a locking screw 77, and a moving plate 78; Figure 3 and Figure 4As shown. The heel portion of the foot-shaped base plate 6 is provided with a silicone pad layer 72, and the top of the silicone pad layer 72 is provided with a mesh layer 71; the side of the silicone pad layer 72 is connected to a rigid support plate 73, and the side of the rigid support plate 73 is rotatably connected to a support plate 75; the top of the support plate 75 is provided with a soft pad 74, and the two sides of the support plate 75 are provided with outward plates 76; the outward plates 76 pass through a limiting groove 63 opened on the side of the foot-shaped base plate 6, and the side of the outward plates 76 is connected to a moving plate 78; the two sides of the limiting groove 63 are provided with locking holes 64, and the locking screw 77 passes through the moving plate 78 and is threadedly connected to the locking holes 64. Therefore, the heel area formed by the mesh layer 71 and the silicone pad layer 72 is the main load-bearing area and needs to be cushioned and shock-absorbing. The midfoot area formed by the rigid support plate 73 provides arch support and maintains stability. The rotatable support plate 75 and the soft pad 74 form the forefoot area: to avoid pressure on the metatarsal heads and to adjust the dorsiflexion angle; during adjustment, rotate to remove the locking screw 77, and then move the moving plate 78 within the limiting groove 63 until the support plate 75 rotates to the appropriate angle, and then insert and rotate the locking screw 77 to fix it.

[0030] When using this utility model, firstly adjust the angle between the shin-shaped base plate 1 and the foot-shaped base plate 6 according to the user's needs. When adjusting, rotate to loosen the locking screw 23, and then move the length of the inner insertion rod 22 inside the outer sleeve rod 24. The angle between the shin-shaped base plate 1 and the foot-shaped base plate 6 can be observed through the protractor 3 until the angle is suitable. Then, rotate the locking screw 23 in the opposite direction so that the locking screw 23 pushes the fixing piece 26 to hug the inner insertion rod 22, thereby fixing this state.

[0031] Adjust the angle of the forefoot area as needed. During adjustment, rotate to remove the locking screw 77, and then move the moving plate 78 within the limiting groove 63 until the support plate 75 rotates to the appropriate angle. Then insert and rotate the locking screw 77 to fix it. Next, place the foot in the foot-shaped base plate 6 and the lower leg in the shin-shaped base plate 1. Then lock the Velcro cable tie 12 and Velcro cable tie 61 to complete the fixation. When walking, the rotating baffle 62 can be placed at the front to protect the toes. When resting and lying down, rotate to open the baffle 1 51 and the baffle 2 52. The baffle 1 51 and the baffle 2 52 can support the foot-shaped base plate 6 and keep the foot-shaped base plate 6 in the center position of the top of the two baffles.
