Description

TECHNICAL FIELD

[0001] The utility model relates to an ankle foot orthosis technical field, concretely is a light multi -functional rear support type ankle foot orthosis. BACKGROUND

[0002] Ankle foot orthosis is a kind of structure from shank to foot bottom, is used to control and limit the ankle joint movement orthosis, can be divided into branch type ankle foot orthosis, plastic ankle foot orthosis, patellar ligament load type ankle foot orthosis etc., the main function of ankle foot orthosis includes fixing joint in normal function position, avoiding the relaxation of ligament after being abnormally stretched, long time tendon traction, antagonizing muscle spasm and compensating partial muscle weakness, ankle foot orthosis can be used for lower limb orthosis, help to improve gait function, reduce the pressure of lower limb structure, in addition, ankle foot orthosis can also be customized according to the specific situation of individual to meet different treatment and support needs.

[0003] The current mainstream ankle foot orthosis manufacturing method is 3D printing technology, traditional handwork high-temperature thermoplastic plate manufacturing, low-temperature thermoplastic plate material, semi-finished high-molecular fiber material and prefabricated type and customized type, 3D printing is benefited from the mature development of current optical scanner technology and 3D printing technology, with the characteristics of high production efficiency, high precision, controllable data, flexible design and light weight, but the corresponding scanning equipment and 3D printing equipment purchase cost is higher, modeling import 3D printing equipment starts to print and cannot be adjusted, at the same time, optical scanning can collect all the data of patient's limbs, which may involve sensitive information, traditional handwork high-temperature thermoplastic plate manufacturing allows to adjust the shape of orthosis at any time during manufacturing process, the cost of hand-made equipment and materials is also lower, and the material performance and durability have been tested in the market for a long time, but hand-made requires the manufacturer to have extremely rich experience and skill, needs long time work and physical labor, and the production method is limited, the product type and function are single, the existing foot and ankle diseases and flat foot diseases cannot be treated at the same time, because the traditional ankle foot orthosis foot bottom plane is consistent with the size of foot, and cannot support the arch, the function of ankle foot orthosis is limited, and the application range is small.

[0004] Therefore, a new light multi -functional rear support type ankle foot orthosis is proposed to solve the above problems. Utility model content

[0005] The utility model aims at providing a light multi -functional rear support type ankle foot orthosis to solve the problems that foot and ankle diseases and flat foot diseases cannot be treated at the same time, cannot support the arch, the function of ankle foot orthosis is limited, and the application range is small in the above background technology.

[0006] To achieve the above object, the utility model provides the following technical scheme: a kind of lightweight multifunctional rear support type ankle-foot orthosis, the inside of the base is provided with arch orthopedic shoe pad, the top of the base is provided with multifunctional auxiliary standing and walking correction assembly;

[0007] The correction assembly includes a first ankle-foot orthosis body and a second ankle-foot orthosis body, which are fixedly connected to the front and rear of the top of one side of the base respectively, and are fixedly connected between the rear end of the outer side of the first ankle-foot orthosis body and the front end of the outer side of the second ankle-foot orthosis body.

[0008] Preferably, the space of the calf slot is larger than that of the Achilles tendon slot, and the inside of the first ankle-foot orthosis body and the second ankle-foot orthosis body is vertically through the reinforcing rib.

[0009] Preferably, the front and rear ends of one side of the base are through the opening of a plurality of air holes, and the air holes are arranged at equal intervals in the inside of the base.

[0010] Preferably, the top of the base is hollow, the hollow part of the base is provided with a limiting inner groove, the limiting inner groove is inserted and connected with the arch orthopedic shoe pad, the outer end of the arch orthopedic shoe pad is connected to the inner wall of the base, and the surface of the inside of the base is fixedly connected with a plurality of adhesive outer layers.

[0011] Preferably, the bottom end of the arch orthopedic shoe pad is connected with the surface of the adhesive outer layer, and the center of the arch orthopedic shoe pad is convex upward.

[0012] Preferably, the bottom of the arch orthopedic shoe pad is provided with a plurality of placing grooves, the inside of the placing grooves is fixedly connected with a plurality of buffer cushions, and the bottom of the buffer cushion is arc-shaped.

[0013] Compared with the prior art, the utility model has the beneficial effects that the lightweight multifunctional rear support type ankle-foot orthosis not only realizes multifunctional correction, realizes disassembly and assembly function, but also realizes buffer stability function.

[0014] (1) The first ankle-foot orthosis body, the second ankle-foot orthosis body, the arch orthotic insole, the Achilles tendon slot and the calf slot are fixed together on the outside of the first ankle-foot orthosis body and the second ankle-foot orthosis body. An open area is designed on the back of the calf and the Achilles tendon. The normal function of the joint is fixed by the calf slot and the Achilles tendon slot. By keeping the ankle joint in a neutral position, the ligaments are prevented from being loosened after abnormal stretching. It assists in standing and walking, corrects deformities, affects muscle tone, and pulls the tendon for a long time to resist muscle contracture. It helps to correct deformities and maintain normal alignment. For patients with insufficient muscle strength, the ankle-foot orthosis can provide additional support to help them carry out daily activities. It provides various correction and fixation functions. At the same time, it can be used with the arch orthotic insole to complete the correction of flat feet and achieve multi-functionality.

[0015] (2) By setting up ventilation holes, adhesive outer layer and limiting inner groove, the arch orthotic insole is inserted and fixed in the limiting inner groove by using the interlocking structure, and multiple sets of adhesive outer layer are used to enhance the connection force, ensuring that the arch orthotic insole will not loosen or even fall off during use. The base provides it with a fully enclosed space to ensure comfort. At the same time, multiple sets of ventilation holes are opened to provide sufficient ventilation protection for both sides of the arch orthotic insole.

[0016] (3) By setting up an orthotic insole, cushioning pads and placement grooves, several sets of cushioning pads are fixedly installed in the corresponding placement grooves to provide strong support and protection for the bottom of the orthotic insole, play a shock-absorbing and comfortable role for the sole of the foot, increase the patient's comfort, and at the same time provide safety protection to avoid foot discomfort caused by excessive hardness of the base during use.
