Description

Adjustable assembled spinal lateral bending brace

Technical Field

The invention relates to an external orthopedic device for scoliosis of human teenagers, in particular to an adjustable assembled scoliosis brace.

Background

The scoliosis of the teenagers is a common spinal deformity in the teenager period, the incidence rate is about 0.3 percent, and the scoliosis can be prevented from being aggravated by early treatment. However, the operation rate of the scoliosis is still high at present, and the main reason is not enough to pay attention to the poor treatment effect of the currently used brace. The braces of Milwaukee, Boston, Lyon, Wilmington and the like are invented in 60 years of the last century, are used for nearly 60 years, are not updated much at present, and play a great role in correcting scoliosis in the past, so that a plurality of children patients can benefit from the braces, and surgical treatment is avoided. However, these braces have some disadvantages, the orthopedic effect on the scoliosis of teenagers is limited, and complete individuation cannot be realized, the force point of the brace for the scoliosis orthopedic is difficult to judge, discomfort and unattractive, and parents and children are difficult to accept. Milwaukee can only guide lateral curvature of the upper thoracic region and is difficult to effectively correct. It is necessary to apply the current new concept and new technology to find an external brace which is comfortable, beautiful and has good orthopedic effect.

Disclosure of Invention

Based on the problems existing in the existing orthopedic brace, the invention aims to provide an adjustable combined type scoliosis brace which has good comfort, good orthopedic effect, easy combination and assembly and is suitable for individual difference.

The purpose of the invention is realized by the following technical scheme: an adjustable matched stack formula scoliosis brace which characterized in that: consists of a shoulder ring, a pelvis ring, an elastic plate and a supporting plate; the elastic plate vertically arranged detachably connects the rear part of the shoulder ring with the rear part of the pelvis ring, and the supporting plate vertically arranged detachably connects the front part of the shoulder ring with the front part of the pelvis ring.

The shoulder ring is matched with the shape of the shoulder position of a human body, and a plurality of screw holes are formed in the front part and the rear part of the shoulder ring; the shoulder ring is used for fixing the shoulder and adjusting the shoulder balance.

The pelvis ring is matched with the shape of the pelvis of the human body, and a plurality of pelvis ring screw holes are formed in the pelvis ring; the pelvis ring is mainly used for fixing the pelvis and is a main fixing fulcrum of the brace.

The two ends of the elastic plate are provided with a plurality of connecting holes, and the connecting holes are connected with the shoulder ring and the pelvis ring screw holes through screws, so that the rear part of the shoulder ring is detachably connected with the rear part of the pelvis ring. The middle part of the elastic plate is provided with a widening expansion area, the widening expansion area is provided with a transverse arc, and the side surface of the elastic plate is a vertical arc.

The two ends of the supporting plate are provided with a plurality of connecting holes, and the connecting holes of the supporting plate are connected with screw holes of the shoulder ring and the pelvis ring through screws so as to realize the detachable connection of the front part of the shoulder ring and the front part of the pelvis ring; the supporting plate is straight.

The elastic plate is vertically arc-shaped, the convex side of the elastic plate is convex to the back, the spine and the thorax (the highest part of the back of the razor) are convex, the widened and expanded area of the section is in contact with the thorax which is convex to the back to exert pressure, the spine of the side process is corrected through the conduction of the force of the thorax, and the rotation of the spine and the thoracic deformity are improved through the correction of the thorax. The expanded part of the middle section of the elastic plate increases the contact surface between the brace and the thorax, prevents the skin from being crushed and increases the orthopedic effect. The arc elastic plate can also ensure continuous pressure application to the apical vertebra area, realize continuous dynamic pressure application and shape correction, and increase the shape correction effect. The pelvis and shoulder balance can be controlled by fixing the pelvis ring and the shoulder ring with the vertically connected supporting plate and the elastic plate at selectable joint points. The straight connecting plate is used for supporting the side bending concave side (the front part of the thorax, which is opposite to the elastic plate through the thorax) to increase the orthopedic effect and increase the fixing strength of the brace.

The shapes and the sizes of the shoulder ring, the pelvis ring, the supporting plate and the elastic plate are all obtained by CT scanning data of a patient and are printed in one step by 3D printing according to body data of the patient. The radian and the pressure of the elastic plate are obtained by finite element analysis, so that effective shape correction is ensured.

The brace provided by the invention is only contacted with key parts of a body, so that the coverage area of the body is greatly reduced, the ventilation performance is increased, the volume and the area of the brace are reduced, the brace is easily covered by clothes worn outside, and the brace is comfortable, attractive, efficient and easy to accept and cooperate with children patients.

The invention is invented by the inventor based on years of clinical experience, and overcomes the defects of the existing brace. The support is used for scoliosis of different types and scoliosis of different severity degrees, and individualized design and application are really achieved. The structure is improved to a great extent, simultaneously, the comfort is increased, the infant patient and the parents can accept easily, and the infant patient is easy to assemble and wear, so that the scoliosis correction capability is improved.
