Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically a knee joint anti-hyperextension orthosis. Background Technology

[0002] Hemiplegic patients commonly exhibit foot drop and knee hyperextension. Some patients with high lower limb muscle tone also have severe foot inversion combined with knee hyperextension and valgus. This abnormal movement is particularly noticeable during the stance phase of walking on the affected lower limb. Currently, ankle-foot orthoses are used clinically to correct foot drop and inversion in patients.

[0003] In the existing technology, anti-hyperextension braces are usually used for knee hyperextension and valgus. However, the two orthoses are used separately, and the fixation effect is not ideal for patients who have both foot inversion and knee hyperextension and valgus. Therefore, a knee joint anti-hyperextension orthosis is proposed to solve the above problems. Utility Model Content

[0004] To address the problems mentioned in the background section, this invention provides a knee joint anti-hyperextension orthosis.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a knee joint anti-hyperextension orthosis, comprising an ankle-foot orthosis and a sleeve, one end of the sleeve being fixedly connected to the ankle-foot orthosis, the other side of the sleeve being adhesively attached to the ankle-foot orthosis via Velcro, the outside of the sleeve being wrapped with a first strap, both sides of the ankle-foot orthosis being movably connected to connecting frames, the middle of the two connecting frames being movably connected to an anti-knee hyperextension device, the top of the connecting frames being movably connected to a thigh connector, and a second strap being provided on the thigh connector.

[0006] Preferably, the connecting frame is made of metal.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0008] This invention utilizes a combination of an ankle-foot orthosis, a connecting frame, an anti-knee hyperextension device, and a thigh connector to achieve the effects of correcting foot drop and inversion, preventing knee hyperextension, and preventing knee valgus. The ankle-foot orthosis employs a stable structure with an immobile ankle joint, effectively fixing the foot and ankle while restricting ankle movement. To limit knee hyperextension and valgus and assist in lower limb support, the anti-knee hyperextension device uses a design that provides support from behind the knee joint to prevent knee hyperextension. On both sides of the knee joint, the connecting frame connects the knee joint portion of the device to the lower leg and ankle joint portions as a whole, ensuring the overall stability of the device, guaranteeing the range of motion of knee flexion and extension, effectively restricting knee valgus, and enhancing the stability of the lower limb during the walking support phase on the affected side.

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0012] like Figure 1 As shown, this utility model provides a knee joint anti-hyperextension orthosis, including an ankle-foot orthosis 1 and a sleeve 2. One end of the sleeve 2 is fixed to the ankle-foot orthosis 1, and the other side of the sleeve 2 is attached to the ankle-foot orthosis 1 by Velcro. The outside of the sleeve 2 is wrapped with a first strap 3. Both sides of the ankle-foot orthosis 1 are movably connected to connecting frames 4. The middle of the two connecting frames 4 is movably connected to an anti-knee hyperextension device 5. The top of the connecting frame 4 is movably connected to a thigh connector 6. A second strap 7 is provided on the thigh connector 6. The connecting frame 4 is made of metal.

[0013] The above scheme is adopted: the ankle-foot orthosis 1 adopts a stable structure with immobile ankle joint to effectively fix the foot and ankle; at the same time, it restricts the movement of the ankle. For limiting knee hyperextension and valgus and assisting lower limb support, the anti-knee hyperextension device 5 adopts a design that provides support from behind the knee joint to prevent knee hyperextension. On both sides of the knee joint, the connecting frame 4 connects the knee joint part of the device with the lower leg and ankle joint parts into a whole, ensuring the overall stability of the device, ensuring the range of motion of knee flexion and extension, effectively restricting knee valgus, and strengthening the stability of the lower limb during the walking support phase of the affected side. This makes the device have the effects of correcting foot drop and inversion, preventing knee hyperextension and preventing knee valgus.
