Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and particularly relates to a breathable ankle-foot dorsiflexion fixator. Background Art

[0002] Foot drop is one of the orthopedic signs. When the patient is sitting and the two lower limbs are naturally hanging down, if the foot is in the plantar flexion position and completely unable to dorsiflex actively and invert / evert, it is foot drop. Patients affected by this disease generally have difficulty walking because when the patient's foot is lifted off the ground, it generally tends to droop. Therefore, to avoid tripping, the patient generally has to lift the foot higher than it should be. Ankle-foot orthosis is generally used to provide protection for the patient's ankle and foot, and at the same time provide support to resist excessive plantar flexion. The ankle-foot orthosis achieves the correction effect by applying force on the patient's limb and can be used to support, protect, correct or protect the patient's limb.

[0003] To solve the above problems, the existing utility model patent with the patent application number: CN201420056009.X and the patent name: "Naked Foot Dorsiflexion Rehabilitation Device" has the technical solution recorded as follows: The naked foot dorsiflexion rehabilitation device includes a footrest plate for foot drop orthosis and a fixing device for fixing the footrest plate on the leg. The fixing device is set as a knee guard plate tied and fixed at the knee. The knee guard plate is hinged to the middle of the footrest plate through a connecting plate. By setting the footrest plate, the knee guard plate, the elastic plate and their connection structures, when the patient walks and lifts the foot, the ankle and foot are in a relaxed state, and when the foot lands, the ankle and foot are in a corrected state. Persistent long-term use can enhance the ankle joint function and promote the rehabilitation treatment of foot drop. Although the above existing technology can solve the rehabilitation treatment of foot drop, this structure cannot solve the problem of fixation after knee joint surgery. Therefore, the present invention provides an ankle-foot dorsiflexion fixator that can not only solve the rehabilitation treatment of foot drop, but also achieve fixation after knee joint surgery, so as to avoid the patient after knee joint surgery from wearing a heavy and non-breathable plaster. Summary of the Utility Model

[0010] Preferably, the second strap buckle is provided with a mounting hole for a rivet to pass through and a second strap opening for the second magic tape to pass through, and the first strap buckle has the same structure as the second strap buckle.

[0011] Preferably, the side surface of the plate body of the front blocking plate is an "L"-shaped long plate body, and the width dimension of the front blocking plate is smaller than the cavity opening dimension between the foot support shell, the calf shell and the thigh shell.

[0012] Preferably, the plate body of the front blocking plate is provided with third ventilation holes.

[0013] Preferably, an arc-shaped threading plate for passing the second magic tape is provided on the surface of the front blocking plate, and a through hole is formed between the plate body of the threading plate and the plate body of the front blocking plate.

[0014] Compared with the prior art, the present utility model has the following beneficial effects: First, the ankle-foot dorsiflexion fixator of the present utility model can not only solve the rehabilitation treatment of foot drop, but also realize the fixation and ventilation after knee joint surgery. Second, for the ankle-foot dorsiflexion fixator of the present utility model, the cavities at the integrally formed shell can accommodate the patient's knees, calves and feet into the cavities to limit the range of activities, ensuring the correction effect of the patient's limbs, and the ankle-foot dorsiflexion fixator has a simple structure and is convenient to wear. Third, an arc-shaped threading plate for passing the second magic tape is provided on the surface of the front blocking plate, so as to more conveniently fix the front blocking plate.

Detailed Description of the Preferred Embodiment

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] As Figures 1-3 shown, a breathable ankle-foot dorsiflexion fixator includes a footrest shell 1, a calf shell 2, a thigh shell 3, and a front blocking plate 9. A calf shell 2 is fixedly connected between the footrest shell 1 and the thigh shell 3. A first strap buckle 4 is provided on one side of the footrest shell 1. A first magic tape 8 for cooperating with the first strap buckle 4 is provided on the other side of the footrest shell 1. Second strap buckles 5 are respectively provided on one side of the calf shell 2 and the thigh shell 3, and second magic tapes 7 for cooperating with the second strap buckles 5 are provided on the other side of the calf shell 2 and the thigh shell 3. A front blocking plate 9 is snapped into the cavities of the footrest shell 1, the calf shell 2, and the thigh shell 3, and the front blocking plate 9 can block the leg and make it easier to fix the leg. First ventilation holes 13 are provided on the calf shell 2 and the thigh shell 3.

[0022] As Figures 1-2 shown, the footrest shell 1 is provided with second ventilation holes 12, and the second ventilation holes 12 are in a long strip shape, so that the foot is also more breathable.

[0023] As shown Figures 1-2 in the figure, the first belt-passing buckle 4 and the first magic tape 8 are respectively fixed to both sides of the footrest shell 1 by rivets 6. The second belt-passing buckle 5 and the second magic tape 7 are respectively fixed to the calf shell 2 and the thigh shell 3 by rivets 6. Fixing with the first magic tape 8 and the second magic tape 7 is more convenient for wearing and fixing.

[0024] As shown Figures 1-3 in the figure, the mounting hole 501 for the rivet 6 to pass through and the second belt-passing opening 502 for the second magic tape 7 to pass through are provided on the second belt-passing buckle 5. The first belt-passing buckle 4 has the same structure as the second belt-passing buckle 5.

[0025] As shown Figures 1-2 in the figure, the side surface of the plate body of the front baffle 9 is an "L"-shaped long plate body, and the width dimension of the front baffle 9 is smaller than the cavity opening dimension between the footrest shell 1, the calf shell 2 and the thigh shell 3.

[0026] As shown Figures 1-2 in the figure, the plate body of the front baffle 9 is provided with a third ventilation hole 11.

[0027] As a preferred way, the footrest shell 1, the calf shell 2 and the thigh shell 3 can also be integrally formed.
