Description

A hallux valgus correction regulator that can be freely bent and adjusted

technical field

The invention relates to the technical field of hallux valgus correctors, in particular to a hallux valgus corrector that can be freely bent and adjusted for use.

Background technique

Hallux valgus refers to the situation where the joint between the hallux phalanx and the first metatarsal is tilted more than 15 degrees. Hallux valgus is caused by a variety of conditions, such as genetics, frequent wearing of high-heeled and pointed shoes, causing the hallux toe to be excessively everted, In addition, patients with flat feet are more likely to develop hallux valgus. Among the patients, there are more women than men, and they are more common in middle-aged and elderly women. Those who are used to wearing high heels and pointed shoes are also prone to the disease.

Hallux valgus is mainly manifested as foot deformity and pain. The deformity is manifested as hallux valgus, which deviates to the direction of other toes, while the metatarsal head at the root of the thumb protrudes obviously. When the deformity is severe, the protrusion of the toe head can be hemispherical. The second toe also protrudes toward the back of the foot due to extrusion. Most patients with severe deformity will experience varying degrees of pain. The pain is mainly due to the protruding part of the metatarsal head, which is squeezed and rubbed by the upper for a long time, causing local skin Thickening, bone hyperplasia, and can produce bursa and bursitis in the subcutaneous area, causing redness, swelling and pain.

technical problem

At present, the existing correcting adjusters generally do not have the effect of automatically adjusting the correcting angle according to the movement rules of the human toes. Even when the degree of valgus of the human toes is relatively serious, they can still flexibly move up or down normally after being controlled by the human body. Downward joint movement, even when the toes are forced to move by external force, for example, when the toes step on a hard object and bend passively, most of the existing correction regulators are forced to pull the toes outward to achieve correction. If the corresponding changes in the correction angle cannot be achieved during joint activities such as bending, it is easy to cause damage to the toes. For this reason, we provide a thumb that can be used freely to bend and adjust the correction angle according to the movement rules of the toes of the human body. Flip the correction regulator.
