Metatarsal bone far-end osteotomy post-operation fixing device

Abstract

The invention discloses a metatarsal bone far-end osteotomy post-operation fixing device, which comprises a fixing band and a toe separating pad, and is characterized in that the fixing band comprises a medical bandage corresponding to a first toe, an inner-layer medical bandage corresponding to a front foot sole and an outer-layer medical glass fiber bandage corresponding to the front foot sole and a first metatarsal bone, the medical glass fiber bandage comprises a rectangular body belt corresponding to the front foot sole, a limiting belt for preventing plantar curvature of the first toe is arranged in front of the body belt corresponding to the first metatarsal bone, the limiting belt is close to the outer side edge of the body belt, the toe separating pad is located between a first toe web and a second toe web, and the rear end of the toe separating pad is pressed between the outer-layer medical glass fiber bandage and the inner-layer medical bandage.

Description

technical field [0001] The invention belongs to the field of rehabilitation engineering, and is a fixing device for patients with hallux valgus after osteotomy of the distal end of the first metatarsal bone. Background technique [0002] Correction of hallux valgus is a common foot deformity, and the incidence rate of women is higher than that of men. It is manifested by the lateral deviation of the big toe of the foot bones, thick bumps and protrusions at the metatarsophalangeal joints, and osteophytes continue to grow , The friction with the external vamp forms bunions, local redness and swelling, and the surface skin forms corpus callosum neuritis, causing pain and paresthesia of the big toe, forming a larger corpus callosum structure. Patients are often accompanied by symptoms such as pain, redness, and swelling, which can lead to unsteady gait and affect normal sports and life. [0003] Hallux valgus correction can be roughly divided into physical correction and surgic...

AI Technical Summary

Problems solved by technology

At present, there is no uniform fixation method clinically, and some fixation is done with screws and Kirschner wires, but after fixation, the range of motion of the forefoot is limited and the pain index is high. The recovery time is prolonged; some bandages, adhesive tapes, gauze or fabrics are used for bandaging and fixing. This method is simple and convenient to operate, and the wound is easy to clean and easy to replace. However, this kind of fabric is soft and easy to deform, and the bandaging is slightly looser. It is not obvious, and it is easy to cause the metatarsal end to fall off after the operation. If the bandage is slightly tight, it will affect the blood flow of the foot and prolong the recovery time of the osteotomy end; It is often mass-produced, and it is mainly suitable for patients with mild symptoms. The purpose is to slow down the aggravation of hallux valgus, and it does not play a role in fixing and maintaining the stability of the metatarsal end after surgery.

Compared with the previous hallux valgus fixation method, it always plays the role of fixation, binding and tying through ankle wrapping. The operation is cumbersome and the effect is not obvious. It usually takes three days for the patient to walk slowly on the ground. Therefore, this kind of fixation delays the patient's recovery time
