The main structure comprises: the foot sole limiting plate 1, the leg limiting cylinder 2 and the driving component 3 are arranged on two sides of the foot sole limiting plate 1, movable shafts 12 are arranged on the two limiting side plates 11, the two sides, close to the foot sole limiting plate 1, of the leg limiting cylinder 2 are respectively provided with connecting terminals 21, the connecting terminals 21 are movably connected with the movable shafts 12, so that the leg limiting cylinder 2 is movably connected with the foot sole limiting plate 1, the driving component 3 is arranged on the leg limiting cylinder 2, and the driving component 3 is used for driving the foot sole limiting plate 1.

It should be noted that, the current ankle-foot orthosis generally does not have an ankle-joint exercise training function, and only covers and limits the ankle joint, so that the ankle foot can only be in a relatively fixed state during the long-term orthopedic treatment. Training of ankle joint movement function is neglected, so that blood blocking and even deep venous thrombosis are extremely easy to cause. According to the utility model, the driving component 3 is arranged at the movable joint between the sole limiting plate 1 and the leg limiting cylinder 2, and the sole limiting plate 1 is driven to move through the driving component 3, so that the ankle joint of a patient can be moved. Thereby realizing the ankle joint exercise training function.

In some embodiments, the limiting plate 11 is integrally formed with the sole limiting plate 1, and at least one of the sole limiting plate 1 and the leg limiting cylinder 2 is provided with the driving component 3.

Further, as shown in fig. 3 and 4, the driving assembly 3 includes: the leg limiting cylinder 2 comprises a shell 31, an upper cover 32, a driving motor 33, a control board 34, a battery 35 and a reduction gear 36, wherein the shell 31 is fixedly connected to the leg limiting cylinder 2 at a position close to the movable shaft 12, the upper cover 32 is arranged on the shell 31, the driving motor 33 is fixedly connected in the shell 31, the control board 34 is arranged in the shell 31, the battery 35 is arranged in the shell 31, and the reduction gear 36 is rotatably connected in the shell 31; wherein, driving motor 33 and battery 35 are all connected with control panel 34 electricity, and driving motor 33's output shaft and gear 36 meshing, gear 36's output shaft and loose axle 12 meshing. In this embodiment, the driving motor 33, the control board 34, the battery 35 and the reduction gear 36 are integrated together, so that the flexibility of the ankle exercise training of the patient can be improved, and no external device is required without receiving external limitation.

In some embodiments, the drive assembly 3 includes a drive motor 33, and the on-off, rotational speed, and direction of transmission of the drive motor 33 are controlled by an external power source or control device.

Further, as shown in fig. 3 and 4, the control board 34 is provided with a control button 37, and the control button 37 penetrates the housing 31. The control board 34 is used to control the switching or rotational speed of the motor, etc.

Meanwhile, the toe limiting strap 13 can limit the sole of the patient on the sole limiting plate 1.

Further, as shown in fig. 1 and 2, a first opening and closing slit 22 is formed on the side wall of the leg limiting cylinder 2, and at least one set of first opening and closing components 23 is disposed on the leg limiting cylinder 2 at a position close to the first opening and closing slit 22.

It should be noted that, most of the conventional orthoses adopt a limiting structure with a fixed size to limit and fix the ankle portion, and lack sufficient adjustable operation. The leg and the foot can be fixed and worn only under the hardness standard of the orthosis, so that the leg and the foot are not comfortable and can be more easily swelled and fatigued. The first opening and closing component 23 and the second opening and closing component 15 with adjustable lengths are adopted in the scheme. In some embodiments, the first and second opening and closing assemblies 23 and 15 may be configured as a connection structure of a velcro or the like that can be adjusted in length and quickly disassembled.

Further, as shown in fig. 2 and 3, the two limiting side plates 11 keep a gap, the heel positions of the two limiting side plates 11 close to the sole limiting plate 1 are mutually closed to form a second open-close seam 14, and the second open-close seam 14 is provided with a second open-close component 15.

The first slit 22 and the second slit 14 are provided on the back in the same direction as each other. When the patient wears the foot protector, the first opening and closing assembly 23 and the second opening and closing assembly 15 are firstly released, so that the first opening and closing seam 22 and the second opening and closing seam 14 are opened, and the sole and the lower leg of the patient can penetrate from the back. Finally, the first opening and closing component 23 and the second opening and closing component 15 are locked.

Further, as shown in fig. 3, the first opening and closing assembly 23 has the same structure as the second opening and closing assembly 15, the first opening and closing assembly 23 includes a strap 231 and a connecting member 232, the strap 231 is detachably connected to the connecting member 232, and one end of the strap 231 is connected to one side of the first opening and closing slit 22 or the second opening and closing slit 14, and the connecting member 232 is disposed on the other side of the first opening and closing slit 22 or the second opening and closing slit 14.

It can be understood that the first opening and closing assembly 23 and the second opening and closing assembly 15 have the same functions, so as to be convenient and quick to assemble and disassemble, and can realize the function of adjusting the length. The first opening and closing member 23 in this embodiment is identical to the second opening and closing member 15 in structure.

Further, as shown in fig. 2, the binding band 231 is provided with a clamping groove 2311 in an aligned manner, and the binding band 231 is clamped with the connecting piece 232 through the clamping groove 2311.

The connector 232 is internally provided with an abutting member engaged with the engaging groove 2311, and the abutting member is engaged with the engaging groove 2311 so that the connector 232 and the binding band 231 are fixed to each other. When the strap 231 needs to be opened, the abutment member is away from the catch 2311, and the strap 231 is released from the connector 232 without restriction. It is to be understood that the specific function of the connecting member 232 in this embodiment is available to those skilled in the art according to the prior art, and the structure and working principle of the connecting member 232 will not be described herein.

Further, as shown in fig. 1, a cushion pad 16 is provided on the sole limiting plate 1. First, the cushion 16 can provide cushioning to help reduce impact forces on the ball of the foot during the training process and avoid discomfort and injury. For example, in some sports rehabilitation exercises, a patient is required to perform a certain high impact motion such as jumping and landing, and the cushion 16 plays an important role in protecting the sole and the lower leg bone from injury due to excessive impact.

Secondly, the cushion pad 16 can also be used as an adjusting device, and according to different training requirements and individual differences of patients, the supporting and limiting degree of the sole limiting plate 1 on the sole can be adjusted by adding or subtracting cushion blocks or replacing cushion blocks with different hardness. Thus, the individual training requirements of the patient can be better met, and a better treatment effect is achieved.

In summary, the utility model provides an ankle orthosis, wherein a driving component 3 is arranged at a movable joint between a sole limiting plate 1 and a leg limiting cylinder 2, and the sole limiting plate 1 is driven to move by the driving component 3 so as to further move the ankle joint of a patient. Thereby realizing the ankle joint exercise training function.
