Correction device for pediatric developmental dysplasia of hip

Abstract

The invention discloses a correction device for pediatric developmental dysplasia of hip. The device comprises a first inverted V-shaped wrist rest suitable for supporting a left knee wrist of a child, a second inverted V-shaped wrist rest suitable for supporting a right knee wrist of the child, and a telescopic adjusting part for adjusting the distance between the first inverted V-shaped wrist rest and the second inverted V-shaped wrist rest to expand a left leg and a right leg of the child. The device provided by the invention has the following effects: two legs of the child can be expandedto abduction to be fixed, so that the corrective treatment of developmental dysplasia of the hip is facilitated; two legs of the child are only supported by the first inverted V-shaped wrist rest andthe second inverted V-shaped wrist rest, so that the child feels comfortable when uses the device; the telescopic adjusting part has an adjustable telescopic length, so that the distance between the first inverted V-shaped wrist rest and the second inverted V-shaped wrist rest can be adjusted, and the distance of the first inverted V-shaped wrist rest and the second inverted V-shaped wrist is conveniently and adaptively adjusted to be suitable for use according to the size and the like of the lower part of a child body; therefore, the device has a good use effect.

Description

technical field [0001] The invention relates to the technical field of medical care products, in particular to a correction device for children with developmental dysplasia of the hip joint. Background technique [0002] Hip dysplasia is a collective term for congenital or developmental structural abnormalities of the hip joint in infancy and childhood, including acetabular dysplasia, dislocation, and subluxation. Early symptoms include asymmetric hip lines, asymmetric thigh lines, and unequal lengths of lower limbs. It is generally believed that the incidence of this disease is 0.1% to 0.3%, and there is a lack of comprehensive and authoritative statistical data in China. Most of them are girls, the ratio of male to female is 1:6, and 20% of children have family history. The etiology is not yet clear, and it may be related to breech delivery, joint laxity, and family history. [0003] For developmental dysplasia of the hip, early diagnosis and treatment are required, and ...

Problems solved by technology

[0005] For infants and young children, when special pantyhose covers are used to wear them, because they are too soft like clothes, they cannot achieve a good effect of stretching their two thighs, making the treatment effect poor. When using Pavlik harness to wear it, because the Pavlik harness has more straps and is tied to the neck, chest, calf and sole of the feet, etc., many strangulation marks will appear on the skin of the infant patient. It causes discomfort. When using a plaster frame to stretch and fix its thigh, the plaster frame needs to be specially made according to the size of the infant, so that it cannot be used universally, and the plaster frame cannot be used according to the recovery degree of the patient's hip joint dysplasia. Make adjustments, so that the use effect is not good

[0006] Therefore, the tools used in the conservative treatment of the existing technology need to be improved and optimized
