Abstract
Description
Technical Field
[0001] This utility model belongs to the field of ankle joint dynamic orthosis technology, and more specifically, it relates to a biomimetic breathable ankle joint dynamic orthosis. Background Technology
[0002] Ankle dynamic orthoses are medical devices used to treat or support the ankle joint, designed to provide dynamic support and protection to help restore normal motor function or prevent further injury. These orthoses are commonly used for ankle injuries, postoperative rehabilitation, or the treatment of certain chronic conditions such as ankle instability and arthritis.
[0003] Some current ankle dynamic orthotics use electric drive structures such as motors to assist in correction. However, the motors increase the overall weight of the wearer's lower body, thus increasing the wearer's physical exertion. Furthermore, electric drive can easily lead to dependence during rehabilitation, making it less effective for self-correction exercises after the wearer is no longer using the device. In addition, some current ankle dynamic orthotics have poor breathability, which can affect comfort with long-term wear.
[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a biomimetic breathable ankle joint dynamic orthosis in order to achieve a more practical purpose. Utility Model Content

[0006] A biomimetic, breathable, dynamic ankle orthosis includes an arc-shaped plate and a shoe body. Several sets of guide rods are symmetrically arranged on both sides of the arc-shaped plate. Each set of guide rods consists of two rods arranged symmetrically vertically. Both ends of each guide rod extend to the inner and outer sides of the arc-shaped plate. A pair of clamps are symmetrically installed at the inner end of the two sets of guide rods located in parallel positions. A threaded block is threadedly connected to the arc-shaped plate at the midpoint of each set of guide rods, with one end of the threaded block extending to the inner side of the arc-shaped plate and rotatably connected to it. The shoe body is rotatably mounted on the bottom end of the arc-shaped plate. A replacement component is installed at the bottom end of the shoe body. Several ventilation holes are provided on the surface of the shoe body. An elastic element is installed between the arc-shaped plate and the shoe body.
[0007] Furthermore, the replacement component includes a plurality of slots, a replacement plate, and a plurality of bolts. The plurality of slots are disposed at the bottom end of the shoe body.

[0027] As attached Figure 1 To be continued Figure 4 As shown:
[0028] This utility model provides a biomimetic breathable ankle joint dynamic orthosis, including an arc-shaped plate 1 and a shoe body 2. Several sets of guide rods 3 are symmetrically arranged on both sides of the arc-shaped plate 1. Each set of guide rods 3 consists of two rods arranged symmetrically vertically. Both ends of each guide rod 3 extend to the inner and outer sides of the arc-shaped plate 1. A pair of clamps 4 are symmetrically installed at the inner end of the two sets of guide rods 3 located in parallel positions. A threaded block 5 is threadedly connected to the arc-shaped plate 1 at the middle position of each set of guide rods 3, and one end of the threaded block 5 extends to the inner side of the arc-shaped plate 1 and is rotatably connected to the arc-shaped plate 1. The shoe body 2 is rotatably installed at the bottom end of the arc-shaped plate 1. A replacement component is installed at the bottom end of the shoe body 2. Several ventilation holes 6 are provided on the surface of the shoe body 2. An elastic element 7 is installed between the arc-shaped plate 1 and the shoe body 2.
[0029] The connection between the arc plate 1 and the shoe body 2 can be rotatably connected by a bearing seat or a hinged rotating shaft 17. The position of the connection between the arc plate 1 and the shoe body 2 can be adjusted according to the position of the user's ankle joint, thereby better simulating the user's ankle joint movement and improving the orthopedic effect. Through the rotation of the threaded block 5, under the limiting action of each set of guide rods 3, the two clamps 4 located in parallel positions move towards each other simultaneously. When wearing the orthosis, the arc plate 1 is fixed to the user's leg by the contact of several pairs of clamps 4 in different positions with the user's leg. Anti-slip pads can be added to the inside of the clamps 4 to increase friction with the user's leg or clothing. The ventilation holes 6 can improve the breathability of the shoe body 2 and reduce the stuffiness and discomfort caused by prolonged wear. The elastic element 7 can provide resistance and limiting traction when the user's foot is raised, and then pull the user's foot back to its original position through its own rebound, thereby achieving the effect of repeated training and orthopedic correction.
[0030] The replacement component includes several slots 8, a replacement plate 9, and several bolts 10. Several slots 8 are located at the bottom of the shoe body 2. The top of the replacement plate 9 is equipped with a plug 11 at a position that matches each slot 8. A threaded hole 12 is provided through one side of the plug 11. Several bolts 10 are installed on both sides of the shoe body 2 at positions that match each threaded hole 12, and the size of the bolt 10 matches the size of the threaded hole 12.
[0031] The replacement plate 9 can protect the contact area between the shoe body 2 and the ground, reducing dirt from directly adhering to the bottom of the shoe body 2 when the user needs to walk on the ground, reducing the wear and tear of debris on the bottom of the shoe body 2, and reducing cleaning costs. When it is necessary to clean and replace the replacement plate 9, the bolt 10 can be removed to release its restriction.
[0032] The bottom of the replacement plate 9 is provided with anti-slip texture 13.
[0033] The anti-slip texture 13 can increase the friction between the replacement plate 9 and the ground.
[0034] A knob 14 is installed on the other side of the threaded block 5.
[0035] Knob 14 allows the user to easily rotate threaded block 5.
[0036] The elastic element 7 includes a pair of connecting seats 15, which are respectively installed on the bottom of one side of the shoe body 2 and on one side of the bottom of the arc plate 1, and an elastic rubber sheet 16 is installed between the pair of connecting seats 15.
[0037] The elastic rubber sheet 16 allows the user's ankle joint to be reset during flexion and extension movements, thereby improving the exercise and correction of the user's ankle joint. At the same time, the individual elastic rubber sheet 16 can reduce the overall weight of the orthosis, thus reducing the burden on the user when using the orthosis for exercise or movement.
[0038] The working principle of this embodiment:
[0039] When wearing this biomimetic breathable ankle joint dynamic orthosis, the user first passes their foot through the arc plate 1 and into the shoe body 2. Then, by rotating each knob 14, under the limiting action of each set of guide rods 3, the two clamps 4 located in parallel positions move towards each other and clamp the sides of the user's leg, thus fixing the arc plate 1 and the shoe body 2 as a whole. After the fixation is completed, the user can perform sitting ankle flexion and extension exercises or walking exercises. During the exercise, the shoe body 2 and the arc plate 1 will rotate together with the relative movement of the user's leg and foot. At the same time, after the user completes a single flexion and extension exercise, the elastic rubber sheet 16 will rebound and reset itself, and exert traction on the user's foot, thereby assisting the user's foot to reset. Example
[0040] Based on Example 1, as shown in the appendix Figure 1 To be continued Figure 6 As shown:
[0041] The elastic element 7 includes a rotating shaft 17, an L-shaped connecting block 18, and a torsion spring 19. The rotating shaft 17 is installed on one side of the bottom end of the arc plate 1. The L-shaped connecting block 18 is rotatably installed on the bottom end of the arc plate 1, and the other end of the L-shaped connecting block 18 is connected to one side of the shoe body 2. The torsion spring 19 is installed on the surface of the rotating shaft 17, and one end of the torsion spring 19 is connected to one side of the L-shaped connecting block 18.
[0042] The torsion spring 19 can be dynamically replaced and adjusted according to the user's orthopedic needs, and can also be replaced according to the user's orthopedic progress. During rotation, the L-shaped connecting block 18 can restrict the position of the user's foot rotation and pull the user's foot back to its original position after a single flexion and extension.
[0043] The working principle of this embodiment:
[0044] When the user finishes wearing the orthosis and is training, the L-shaped connecting block 18 can restrict the position of the user's foot rotation and pull the user's foot back to its original position after a single flexion and extension. The torsion spring 19 can be set more flexibly according to the user's orthotics needs, thereby improving the flexibility and orthotics effect of the orthosis.

Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
