Frog type hip joint fixing support

Abstract

The invention discloses a frog type hip joint fixing support which comprises shoulder belts, a waist fixing belt, a waist fixing belt cushion, hip circumference plate cushions, thigh circumference plate cushions, thigh fixing belts, square plastic rings, thigh circumference plates, adjustable aluminum alloy back plates, plastic back plates, adjustable thigh supporting strips, right-angled connecting plates, copper sliding blocks and dial discs. The adjustable aluminum alloy back plates and the plastic back plates are connected through bolts, one end of each shoulder belt is connected with the corresponding plastic back plate through a snap fastener, and the other end of each shoulder belt penetrates through the waist fixing belt. The right-angled connecting plates, the copper sliding blocks and the dial discs are fixed to the adjustable aluminum alloy back plates, the right-angled connecting plates are connected with the adjustable thigh supporting strips, and the adjustable thigh supporting strips are connected through the thigh circumference plates through bolts. The hip joint abduction angle is adjustable, the hip flection angle is adjustable, and the frog type hip joint fixing support is mainly used for expectant treatment on hip joint dislocation and subluxation of a child who is six months to three years old or second-stage fixing by replacing a pair of traditional closed reduction gypsum trousers.

Description

technical field [0001] The invention relates to a medical device, in particular to a frog-type hip joint fixation brace. Background technique [0002] Congenital dislocation of the hip joint is a relatively common congenital deformity in children. It is characterized by the loss of the normal apposition relationship between the femoral head and the acetabulum in the joint capsule, so that it cannot develop normally before and after birth and affects walking. Most patients Avascular necrosis of the femoral head occurs in adults with serious consequences and is a disabling disease. The principle of treatment of this disease is early diagnosis and timely treatment. Treatment should begin as soon as the diagnosis of congenital dislocation of the hip is established after birth; the older the age at which treatment is initiated, the less effective it is. [0003] At present, the traditional treatment method is to adopt conservative treatment or surgical treatment. Conservative t...

Problems solved by technology

[0003] At present, the traditional treatment method is to adopt conservative treatment or surgical treatment. Conservative treatment is fixed treatment with frog-style plaster or frog-style orthosis. The purpose of frog-style plaster fixation is to stabilize and shape the femoral head in the acetabulum. Joints, but strenuous activities will cause the femoral head to prolapse again. At the same time, the course of the disease is long, and the course of treatment takes 6 months. The film is reexamined once a month, and the fixing device is adjusted. It is not easy to care. During the 6-month treatment period, the child is fixed. In the frog position, you can only take the supine position, and you cannot turn over, sit, stand, or crawl, which affects eating and urine and stool management, and seriously affects the growth and development of the child; the frog-style orthosis has disadvantages such as insufficient external fixation force and easy loosening. , so that the femoral head of the hip joint on the affected side lacks effective fixation after reduction, and the possibility of re-dislocation is high; and in the frog position, the medial femoral circumflex artery passing through the adductor longus muscle and the iliopsoas muscle is compressed, which directly affects Femoral head blood supply; in frog position, the enlarged labrum can compress the epiphyseal groove, which will affect the development of the femoral head and even cause deformity
