Description

Walking brace for patients with ankle sprains

technical field

The utility model relates to an auxiliary device for walking of patients with ankle joints, in particular to a walking brace for rehabilitation of patients with ankle joint sprains.

Background technique

At present, the clinical treatment of acute ankle ligament injuries at home and abroad follows the conservative treatment of the Policemm principle (protection, appropriate weight bearing, ice pack, compression pack, and raising the limbs). Proper rest, ice pack, press pack, Active functional therapy exercises begin after extremity elevation and early weight bearing.

At present, there are many treatment methods for acute ankle ligament injury, and the effects are different. There is still a lot of controversy in the clinic about the treatment and treatment principles of acute ankle ligament injury.

At present, the relatively unified understanding of the treatment methods for acute ankle ligament injuries is: proper exercise with the assistance of external support, rather than static rest in bed.

Through ankle joint anatomy and biomechanical research, when the ankle joint (tibiotalar joint) is maintained in a neutral position and dorsiflexion, the tibiotalar joint is in the most stable anatomical structure and the state of less stress on the inner and outer malleolus ligaments, controlled by a suitable brace Maintain the stable structure of the ankle joint to achieve the purpose of early functional treatment.

In the prior art, a wearable and adjustable ankle joint device for patients with foot drop is disclosed, Chinese patent CN217390979U, this technical solution is aimed at patients with foot drop, in order to stretch and improve the contracted calf triceps and Achilles tendon, Make the affected foot wear a wedge with a hypotenuse side and fix it on the plantar forefoot, so that when standing or walking on the ground, the foot is forced to have an upward angle relative to the heel, stretching the patient's calf triceps or contracted Achilles tendon , get rehabilitation training. Due to the different purpose of the design, if it is applied to patients with acute ankle sprains and injuries to the medial and lateral ligaments, there are obvious defects. Wearing adjustable ankle joint wedges is assembled under the ball of the forefoot, which is under the head of the foot and forces it to face up relative to the ground. From the beginning, the activities of the tarsal joint, intertarsal joint and heel-tarsal joint are ignored, and the range of motion of the ankle joint cannot be well controlled; especially when striding in walking, the foot drop cannot be controlled; the design of the wedge is narrower than that of the forefoot , similar to forefoot high-heeled shoes, can stand upright, is extremely unstable when walking, and is prone to secondary injury of the patient's ankle joint; it is not suitable for ankle sprains, internal and external malleolus ligaments, ankle fixation and walking.

Utility model content

In order to solve the deficiencies in the prior art and realize walking while standing with a fixed support, the utility model discloses a walking support for patients with ankle joint sprains.

The technical scheme adopted by the utility model to realize the purpose of the invention is:

A walking brace for patients with ankle sprains, the walking brace is connected to the sole, and the walking brace corresponds to the shape of the sole;

The brace is a wedge-shaped body composed of an upper surface corresponding to the shape of the sole and a bottom surface at a designed angle with the ground;

The wedge-shaped body formed by the upper surface and the bottom surface is a wedge-shaped body whose thickness gradually decreases from the front end of the sole to the rear;

The wedge angle formed by the upper surface and the bottom surface is smaller than or equal to the wedge angle of the user's ankle joint dorsiflexion.

The beneficial effects of the utility model are: for the brace for acute ankle sprains, along the front-to-back direction of the foot, cooperate with the sole of the foot so that the slope of the wedge-shaped body faces backwards and forms a supporting contact with the sole of the sole of the foot; The surface of the sole or the inner sole of the shoe is connected or integrally formed to form a contact support with the whole sole of the foot, and when it reaches the walking or upright state, it forms a stable restriction, support, or sliding and rubbing of the ankle. The structure is simple and the connection methods are diverse. Through the study of ankle joint anatomy and biomechanics, the walking brace can maintain the ankle joint and ligaments in the most stable anatomical position during walking. effect. It achieves the purpose of fixed support and early weight-bearing walking after sprain, recovery of basic life, study and light physical work, and promotion of rehabilitation.

Detailed ways

Referring to the accompanying drawings, a walking brace for a patient with an ankle sprain, the walking brace is connected to the sole, and the walking brace 1 corresponds to the shape of the sole 2;

The support 1 is a wedge-shaped body composed of an upper surface 1-1 corresponding to the shape of the sole and a bottom surface 1-2 at a designed angle with the upper surface 1-1;

The wedge-shaped body formed by the upper surface 1-1 and the bottom surface 1-2 is a wedge-shaped body whose thickness gradually decreases from the front end of the sole to the rear;

The wedge-shaped body formed by the upper surface 1-1 and the bottom surface 1-2 is smaller than or equal to the dorsiflexion angle of the user's ankle joint.

In the embodiment of the present utility model, one end of the upper surface 1-1 and the bottom surface 1-2 of the brace 1 is connected via a rotating shaft 1-5 to form a wedge-shaped body with a variable angle between the upper surface 1-1 and the bottom surface 1-2. A return spring 1-6 is arranged between the above-mentioned upper surface 1-1 and the bottom surface 1-2.

In this embodiment, the return spring 1-6 is a linear spring fixed on the other end of the upper surface 1-1 and the bottom surface 1-2 away from the rotating shaft 1-5 or a torsion spring arranged on the rotating shaft 1-5.

In this embodiment, when the patient is walking, the return springs 1-6 can play an auxiliary support role for the ankle joint, and the ankle joint can appropriately increase the force of the ankle joint according to the improvement of the patient's condition.

During walking, the angle of the wedge can change with the magnitude of the elastic force as the wedge is subjected to pressure.

In this embodiment, the bottom surface 1-2 is provided with rubbing rollers 3-1 at the maximum or minimum thickness end of the wedge-shaped body or the bottom surface 1-2 is provided with a sliding pad 3-2.

The purpose that roller 3-1 and sliding aid pad 3-2 are set by rubbing is that this walking brace 1 makes the patient's injured instep be the front end tilted posture. Rubbing roller 3-1 and sliding pad 3-2 reduce the frictional resistance with the ground when the wedge moves. It is convenient for patients to walk (see accompanying drawings 1 and 9).

Sliding pad 3-2 Teflon material, wear resistance, noise reduction and sliding effect is obvious.

In the embodiment of the present utility model, the bottom surface 1-2 and the upper surface 1-1 form a designed angle along the width direction of the upper surface 1-1, which constitutes a tilting posture toward the inside of the human body or toward the outside of the human body when the wedge-shaped body supports the ankle joint. supporting structure. (see accompanying drawings 3 and 4). Reduce the stretch on the sides of the ankle joint.

In the embodiment of the utility model, the upper surface 1-1 of the support is fixedly arranged on the sole 2 or the upper surface 1-1 of the walking support and the sole 2 form an integral structure. A special treatment rehabilitation shoe with the brace is formed.

In the embodiment of the utility model, the rubbing roller 3-1 is a universal roller. It is convenient for patients to move and walk in any direction.

In the embodiment of the present utility model, in the structure of the wedge-shaped body formed by the upper surface 1-1 and the bottom surface 1-2, the upper surface 1-1 is provided with the installation card position 1-3 and the binding belt 1-3 of the patient's foot or shoe. 4. During use, the patient's injured foot or the shoes on the injured foot are arranged in the mounting position 1-3 and fixed by the binding strap 1-4.
