Description

Technical Field

[0001] The utility model relates to the technical field of ankle-foot orthosis, in particular to an ankle-foot orthosis device. Background Art

[0002] Ankle-foot orthosis is an important medical assistive device, mainly used to correct ankle and foot deformities and provide stability to the joints. It can effectively limit abnormal ankle movement and prevent injuries such as sprains and dislocations. It is particularly effective for ankle instability caused by muscle weakness or spasms due to neurological diseases. At the same time, for congenital or acquired foot deformities such as equinus, flat feet, inversion, and valgus, ankle-foot orthosis can gradually correct the deformity and improve the appearance and function of the foot by applying appropriate pressure and traction. In addition, it can also improve the patient's gait, increase walking safety and comfort, and play an important role in rehabilitation treatment and daily life.

[0003] Ankle-foot orthosis devices available on the market use straps to control the angle between the foot and calf. However, straps generally have a certain degree of deformation and poor strength, making them unsuitable for patients with severe foot drop. In addition, the straps do not provide precise control over the angle. Therefore, to address the above-mentioned issues, an ankle-foot orthosis device was proposed to meet the needs of actual use. Utility Model Content

[0004] The utility model provides an ankle-foot orthosis device, which solves the technical problems in the background technology.

[0005] To solve the above technical problems, the present invention provides an ankle-foot orthosis device, comprising a foot sleeve, an ankle cuff, and a traction assembly, wherein the foot sleeve comprises a foot pad, a foot wrapping portion, a first adjustment strap, and a second adjustment strap, wherein the foot wrapping portion is fixedly connected to the top edge of the foot pad, the first adjustment strap and the second adjustment strap are movably mounted on the instep of the foot wrapping portion, and a connecting block is fixedly mounted on the ankle of the foot wrapping portion; the ankle sleeve comprises an ankle wrapping portion, a third adjustment strap is movably connected to one side of the ankle wrapping portion, and a side surface of the ankle wrapping portion is rotatably connected to the connecting block;

[0006] The traction assembly includes a base, the side of the base is connected to a knob buckle by rotating through a ratchet mechanism, the side of the knob buckle is rolled up with a traction belt, one end of the traction belt is fixedly installed with a connecting column, the base is fixedly installed on the side of the ankle wrapping part, the connecting column is fixedly installed on the side of the foot pad, and the traction belt uses a rubber-coated steel wire rope.

[0007] Preferably, the ankle wrapping portion is U-shaped to wrap the ankle, and a silicone pad is bonded to the inner side of the ankle wrapping portion, and the silicone pad fits the ankle.

[0008] Preferably, the inner walls of the foot wrapping part and the ankle wrapping part are both bonded with sweat-absorbing and breathable layers.

[0009] Preferably, the first adjustment strap, the second adjustment strap and the third adjustment strap are all adjusted in length by Velcro.

[0010] Compared with related technologies, the ankle-foot orthosis device provided by the present invention has the following beneficial effects:

[0011] This utility model provides an ankle-foot orthosis device based on a traditional ankle-foot orthosis. The knob allows for gradual adjustment of the orthotic angle by turning, making the adjustable angle more precise and changing the force application position of the orthosis, maximizing the device's utilization. A silicone pad is added to the ankle, providing greater elasticity and cushioning than traditional EVA pads, making it more user-friendly for bedridden patients, even those with skinny skin. The use of a rubberized steel wire rope, replacing the commonly used straps, provides increased strength and provides greater traction for patients with severe foot drop, meeting the rehabilitation needs of patients with high muscle tone.
