Description

Adjustable Modular Scoliosis Brace

technical field

The invention relates to an extracorporeal orthopedic device for human adolescent scoliosis, in particular to an adjustable and assembled scoliosis brace.

Background technique

Adolescent scoliosis is a relatively common spinal deformity in adolescence, with an incidence rate of about 0.3%. Early detection and early treatment can well prevent the aggravation of spinal deformity. However, the current surgical rate of scoliosis is still very high. The main reason is not enough attention, but also related to the poor treatment effect of the currently used braces. Milwaukee, Boston, Lyon, Wilmington and other braces were basically invented in the 1960s. After nearly 60 years of use, they still haven't been updated much. They have played a great role in the correction of scoliosis in the past. The role of the treatment has benefited many children and avoided surgical treatment. However, these braces have some drawbacks, the orthopedic effect on adolescent scoliosis is limited, and they cannot be completely individualized. accept. Milwaukee can only guide the upper thoracic scoliosis, and it is difficult to correct it effectively. This requires the application of new concepts and new technologies to find an extracorporeal brace that is both comfortable and beautiful and has a good orthopedic effect.

SUMMARY OF THE INVENTION

Based on the problems existing in the existing orthopedic braces, the purpose of the present invention is to provide an adjustable and assembled scoliosis brace with good comfort, good orthopedic effect, easy combination and assembly, and adaptation to individual differences.

The object of the present invention is achieved through the following technical solutions: an adjustable and assembled scoliosis brace is characterized in that: it is composed of a shoulder circle, a pelvis circle, an elastic plate and a support plate; The rear part of the ring is detachably connected with the rear part of the pelvis ring, and the vertically arranged support plate connects the front part of the shoulder ring and the front part of the pelvis ring detachably.

The shoulder ring is adapted to the shape of the shoulder position of the human body, and a plurality of screw holes are arranged at the front and rear of the shoulder ring; the shoulder ring is used to fix the shoulder and adjust the balance of the shoulder.

The pelvic ring is adapted to the shape of the human pelvis, and the pelvic ring is provided with a plurality of pelvic ring screw holes; the pelvic ring is mainly used to fix the pelvis and is the 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 pelvic ring screw holes through screws, so as to realize the detachable connection between the rear part of the shoulder ring and the rear part of the pelvis ring. The middle part of the elastic plate is provided with a widening and expanding area, the widening and expanding area is provided with a horizontal arc, and the side surface of the elastic plate is a vertical arc.

The two ends of the support plate are provided with a plurality of connection holes, and the connection holes of the support plate are connected with the screw holes of the shoulder ring and the pelvis ring by screws to realize the detachable connection between the front part of the shoulder ring and the front part of the pelvis ring; the support plate is straight.

The vertical arc of the elastic plate is convex to the kyphotic spine and thorax (the highest part of the razor back), and the widened and enlarged area of the middle segment is in contact with the rearward protruding thorax to put pressure on it, and correct the scoliosis through the conduction of thoracic force. The spine, while improving the rotation of the spine and thoracic deformity through the correction of the thorax. The enlarged part of the middle section of the elastic plate increases the contact surface between the brace and the thorax, prevents skin crushing, and increases the orthopedic effect. The curved elastic plate can also ensure continuous pressure on the apical vertebrae, so as to achieve continuous and dynamic pressure correction and increase the correction effect. The balance of the pelvis and shoulders can be controlled by fixing the pelvis and shoulder rings with the vertically connected support plates and elastic plates at selectable joint points. The straight connecting plate is used to support the concave side of the scoliosis (in front of the thorax, opposite to the elastic plate through the thorax) to increase the orthopedic effect and increase the fixation strength of the brace.

The shape and size of the shoulder ring, pelvis ring, support plate and elastic plate are obtained from the patient's CT scan data and 3D printed according to the patient's body data. The radian and pressure of the elastic plate are obtained by finite element analysis to ensure effective orthosis.

The brace provided by the invention only contacts the key parts of the body, greatly reduces the coverage area of the trunk, increases the air permeability, reduces the area and area of the brace, is easily covered by clothes worn outside, and is comfortable and beautiful. Efficient, easy for children to accept and use together.

The present invention is invented by the inventor on the basis of years of clinical experience, and overcomes the defects of the existing braces. This brace is truly individualized design and application for different types of scoliosis and scoliosis of different severity. The structure has been improved to a large extent, and the comfort has been increased at the same time. It is easy for children and parents to accept, and it is easy to cooperate with assembly and wear, thereby improving the ability to correct scoliosis.
