Description

Ankle joint sprain patient walking brace

Technical Field

The utility model relates to an auxiliary instrument for walking of ankle joint patients, in particular to a walking brace for rehabilitation of ankle joint sprain patients.

Background

At present, the conservative treatment (protection, proper load, ice compress, compression bag and limb elevation) for clinically treating acute ankle ligament injury at home and abroad follows the Policemm principle, and positive function treatment exercise is started after proper rest, ice compress, compression bag and limb elevation under ankle protection and early load.

At present, the treatment methods for the acute ankle ligament injury are relatively more, the effects are different, and the treatment and treatment principles for the acute ankle ligament injury are also relatively great in clinic.

The current unified recognition of the treatment method of the acute ankle ligament injury is that: with the aid of external support, proper movement is performed, rather than bedridden static rest, but the existing various methods for protecting and fixing the brace equipment and the like still cannot meet the requirements.

Through ankle joint dissection and biomechanical study, when the ankle joint (shank joint) is maintained in a neutral position and a dorsi-extension position, the shank joint is in the most stable anatomical structure and in-and-out ankle ligament smaller stress state, and the stable structure of the ankle joint is controlled and maintained through a proper brace so as to achieve the aim of early function treatment.

In the prior art, an adjustable ankle joint ware can be dressed to patient with drop foot is disclosed, chinese patent CN217390979U, this technical scheme is to drop foot patient, for the triceps and achilles tendon of shank that traction improves contracture, makes the wedge that the hypotenuse was dressed backward to the affected foot be fixed in the plantar forefoot, when can stand or walk to fall to the ground like this, forces the foot to have the angle of rising relative heel, stretches patient's triceps or contracture's achilles tendon, obtains rehabilitation training. Because the design purpose is different, if the adjustable ankle joint device wedge block is applied to patients with acute ankle sprain inner and outer ligament injury, obvious defects exist, and the adjustable ankle joint device wedge block is worn under the front sole, so that the lower part of the foot cudrania bone is forced to be upward relative to the ground level, the movements of the cudrania tarsalis joint, the tarsal joint and the calcaneal joint are ignored, and the ankle joint movement degree cannot be well controlled; particularly when walking mid-stride, foot drop cannot be controlled; the wedge-shaped block is narrower relative to the front foot, is similar to a high-heeled shoe of the front foot, is upright and can walk very unstable, and is easy to cause secondary injury of the ankle joint of a patient; is not suitable for fixing and walking of ankle injury caused by ankle sprain inner and outer ankle ligaments.

Disclosure of Invention

In order to solve the defects in the prior art, realize the fixed support standing and walk at the same time, the utility model discloses a walking brace for ankle sprain patients.

The technical scheme adopted for realizing the aim of the utility model is as follows:

the walking support is connected with the sole, and the walking support corresponds to the sole in shape;

the support consists of a wedge-shaped body which is formed by an upper surface corresponding to the shape of the sole and a bottom surface forming a designed included angle with the ground;

the wedge body formed by the upper surface and the bottom surface is a wedge body with the front end of the sole gradually decreasing in thickness backwards;

the included angle of the wedge-shaped body formed by the upper surface and the bottom surface is smaller than or equal to the back extension angle of the ankle joint of the user.

The beneficial effects of the utility model are as follows: the brace for acute ankle sprain is matched with the sole along the front-back direction of the foot, so that the inclined surface of the wedge body is backwards and forms supporting contact with the whole sole of the sole; or form contact support with the sole of foot through forming connection or integrated molding with the sole of a sock, sole or insole surface, etc., and form stable restriction, support or sliding and rubbing of ankle movement when walking or standing. The walking brace has the advantages that the structure is simple, the connection mode is various, the ankle joint and the ligament can be maintained at the most stable anatomical position in walking through ankle joint dissection and biomechanical study, and the effect is highlighted by rubbing the pulleys and the sliding assisting pad. The aims of fixing and supporting, sprain early-stage load walking, recovering basic life, learning and light physical work and promoting rehabilitation are achieved.

The present utility model will be described in detail with reference to the accompanying drawings.

Detailed Description

Referring to the attached drawings, a walking support for ankle sprain patients is connected with a sole, and the walking support 1 corresponds to the sole 2 in shape;

the support 1 is a wedge-shaped body which is formed by an upper surface 1-1 corresponding to the shape of the sole and a bottom surface 1-2 forming a design included angle with the upper surface 1-1;

the wedge body formed by the upper surface 1-1 and the bottom surface 1-2 is a wedge body with the front end of the sole gradually decreasing in thickness backwards;

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

In the embodiment of the utility model, one end of the upper surface 1-1 and one end of the bottom surface 1-2 of the support 1 are connected through 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, and a return spring 1-6 is arranged between the upper surface 1-1 and the bottom surface 1-2.

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