Description

Technical Field

[0001] The invention relates to a dynamic foot and ankle orthosis, belonging to the technical field of orthoses. Background Art

[0002] Dynamic ankle-foot orthosis is an orthosis used to improve ankle and foot function. It can provide light, flexible and effective support for the ankle and foot, improve the stability of the ankle joint, and enable the sole of the foot to obtain excellent autonomous feedback from the ground. It is made of special custom-molded materials and has close wrapping contact with the ankle-foot joint and the back of the foot when used.

[0003] A Chinese patent publication (publication number: CN 213283620 U) discloses a dynamic ankle-foot orthosis for assisting dorsiflexion, comprising a calf fixing plate, a foot element and a spring booster block, wherein a U-shaped interlaced rail is arranged on the back of the calf fixing plate, a support platform is arranged on the foot element, and support ribs are symmetrically arranged between the foot element and the support platform in an integrated manner, the lower end of the calf fixing plate is hinged on the support platform, a leg fixing belt is arranged on the calf fixing plate, and a foot fixing belt is arranged on the foot element, the spring booster block comprises a shell and a movable block, the shell is interlaced in the U-shaped interlaced rail, a spring is fixedly arranged between the movable block and the shell, a convex block is arranged on the support platform, and an ankle fixing belt is arranged between the support ribs. The invention is made of polymer carbon fiber material, has high strength and light weight, and the orthosis has the advantages of helping ankle dorsiflexion during the swinging period of walking, stabilizing both sides of the ankle joint, improving heel force, limiting inappropriate plantar flexion, and being comfortable and convenient to wear, and is worthy of promotion;

[0004] The positions of the shell and the movable block in the resistance structure of the above-mentioned device are relatively fixed, and the two are not in direct contact. Only when the calf fixing plate and the foot element are at ninety degrees can the protrusion squeeze the spring. However, when the patient walks, the interlaced protrusions and springs and other components will move in a circular direction, so that when the spring releases the downward pressure and releases the elastic force, the elastic force is released in an upward direction, and the elastic force cannot be released synchronously with the direction of movement of the calf fixing plate, resulting in a poor assist effect.

[0005] To this end, a dynamic ankle orthosis is proposed. Summary of the invention

As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0032] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0033] Example 1

[0034] like Figure 1 , Figure 4 and Figure 5 As shown, an embodiment of the present invention provides a dynamic foot and ankle orthosis, comprising a foot segment 1, a support frame 3 is fixedly mounted on the top of the foot segment 1, and a leg segment 4 is arranged on the top of the support frame 3;

[0035] The surface of the support frame 3 is provided with a power-assisting structure 2, which includes a cylinder 201. The two cylinders 201 are fixedly installed on the left and right sides of the support frame 3. The inner cavities of the two cylinders 201 are fixedly installed with circular sheets 202. The tops of the two circular sheets 202 are fixedly connected with power-assisting springs 203. The other ends of the two power-assisting springs 203 are movably connected to the tops of the inner cavities of the two cylinders 201. The tops of the two circular sheets 202 are fixedly installed with mounting rods 204. The bottoms of the two circular sheets 202 are fixedly installed with connecting rods 205. The two connecting rods A movable block 206 is fixedly installed at the bottom of 205, and a clamping block 207 is movably connected to the outer side of the two movable blocks 206. The two clamping blocks 207 are fixedly installed on the left and right sides of the support frame 3. A first slot 208 is opened at the top of the two cylinders 201, and two mounting rods 204 pass through the inner cavity of the two first slots 208 and extend to the top of the two cylinders 201. A second slot 209 is opened at the bottom of the inner cavity of the two cylinders 201, and two connecting rods 205 pass through the inner cavity of the two second slots 209 and extend to the bottom of the two cylinders 201.

[0036] By setting the power-assisting structure 2, when the patient walks, the leg segment 4 swings and drives the cylinder 201 to move in a circular direction. At this time, the cylinder 201 synchronously drives the circular piece 202 and the movable block 206 to swing. At this time, the pressure on the power-assisting spring 203 gradually decreases, and the cylinder 201 and the movable block 206 are pushed to move in opposite directions through the tension of the power-assisting spring 203 itself, thereby saving the patient from applying force to the bending of the leg segment 4 and the support frame 3 when walking, saving the patient from still having to compensatorily lift the affected side when walking, ensuring the treatment effect, and facilitating the use of the operator. By setting the first notch 208, the mounting rod 204 can be limited to avoid the mounting rod 204 from deflecting when moving, thereby affecting the power-assisting effect. By setting the second notch 209, the movement of the connecting rod 205 can be limited to avoid the connecting rod 205 from deflecting when moving, thereby affecting the power-assisting effect.

[0037] Example 2

The right side of the foot segment 1 and the left side of the leg segment 4 are fixedly installed with a first magic strap 6, and the left side of the foot segment 1 and the left side of the leg segment 4 are fixedly installed with a second magic strap 7, and the materials of the second magic strap 7 and the first magic strap 6 are elastic elastic bands, and the surfaces of the three second magic straps 7 are fixedly installed with adhesives 9, and the surfaces of the three first magic straps 6 are fixedly installed with adhesives 8. The inner sides of the leg segment 4 and the foot segment 1 are both arc-shaped, the front side of the top of the foot segment 1 is curved, the left and right sides of the support frame 3 are fixedly installed with a rotating shaft 10, the outer sides of the two rotating shafts 10 are movably connected to the left and right sides of the leg segment 4, the surface of the top of the foot segment 1 and the surfaces of the inner sides of the support frame 3 and the leg segment 4 are all provided with a base layer 11, the surface of the base layer 11 is fixedly installed with an elastic layer 12, and the material of the elastic layer 12 is elastic rubber, the surface of the elastic layer 12 is adhered with a sweat-absorbing layer 13, and the material of the sweat-absorbing layer 13 is sterile sweat-absorbing cotton.

[0039] By setting the ventilation hole 5, the ventilation of the foot section 1 can be improved, which is convenient for patients to dissipate heat from their feet when wearing the shoes in summer. By setting the second magic strap 7 and the first magic strap 6, due to the characteristics of the materials of the two, they can surround legs and feet of different sizes, which is convenient for patients of different body shapes to wear. By setting the adhesive patch 9 and the adhesive patch 8, the second magic strap 7 and the first magic strap 6 can be adhered to each other, thereby improving the convenience of wearing the foot section 1 and the leg section 4. Segment 1, since both of the inner sides are arc-shaped, can be matched with the shape of human feet and legs, thereby improving the comfort of patients wearing the device. By setting the rotating shaft 10, the leg segment 4 and the foot segment 1 can be movably connected, so that the patient's feet and legs have room to move when walking. By setting the elastic layer 12, the comfort of wearing the device can be improved, and a cushioning effect can be achieved when the patient's affected limb walks. By setting the sweat-absorbing layer 13, the patient's sweat can be absorbed when wearing the device, thereby improving the comfort of patients wearing the device.

[0040] When the present invention is working: first, when the patient is in an upright state, the movable block 206 and the connecting rod 205 are in a vertical state, and push the circular piece 202 to move upward. At this time, the assisting spring 203 is deformed due to extrusion, and the circular piece 202 drives the mounting rod 204 to move upward. When the patient walks, the foot segment 1 and the leg segment 4 swing. At this time, the cylinder 201 swings synchronously with the leg segment 4, and the movable block 206 drives the connecting rod 205 to swing synchronously. At this time, with the swing of the connecting rod 205, the circular piece 202 gradually moves downward. At this time, the pressure gradually disappears, and the assisting spring 203 is deformed again, and the elastic force is released synchronously, pushing the movable block 206 and the cylinder 201 to move in opposite directions, thereby achieving the assisting effect of the swing of the support frame 3 and the leg segment 4 when the patient walks.

[0041] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of various changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention.
