Orthosis for scoliosis and its manufacturing method

Abstract

An orthosis for scoliosis and its manufacturing method, comprising an orthosis main body, an orthopedic structure, a first orthopedic force application area, a second orthopedic force application area and a third orthopedic force application area; the orthosis main body is unilateral A cylindrical structure with a longitudinal opening that fits the human spine segment. There are openings on both sides of the main body of the orthosis. Orthopedic structures are arranged in the openings on both sides. The orthopedic force application area is located in the middle of the side, and the other side is provided with a second orthopedic force application area and a third orthopedic force application area. The second orthopedic force application area and the third orthopedic force application area are respectively located at the upper and lower ends of the side surface. Form a three-point corrective force system; the present invention provides a customized orthosis device and design method, which can adapt to the topography of the body surface, and the variable stiffness feature can accurately correct the orthopedic part of the patient while reducing the need for orthopedic The number of device dependencies.

Description

technical field [0001] The invention belongs to the technical field of external fixation orthoses, in particular to an orthosis for scoliosis and a manufacturing method thereof. Background technique [0002] Scoliosis is a curvature of one or more segments of the spine laterally deviated from the midline of the body in the coronal plane, forming a curved spinal deformity, usually accompanied by rotation of the spine and kyphosis or protrusion in the sagittal plane increase or decrease. Existing solutions include a series of physical methods such as orthotics, chiropractic, and kinesiology. Reasonable use of non-surgical orthopedic braces can effectively control the development of scoliosis when the age is young and the Cobbs angle is less than 45°. However, the orthotics used for orthopedic braces need to adjust the orthopedic stress in stages according to different stages of orthopedics. Currently, commonly used thoracolumbosacral braces such as Charleston flexion brace, ...

AI Technical Summary

Problems solved by technology

The above-mentioned braces are almost all made of homogeneous materials. Due to the needs of orthopedics, the elastic modulus of the materials is almost greater than that of the wearing limbs. Stress concentration in the application area (that is, the contact area between the brace and the skin) causes skin abrasion and ulceration, which leads to poor orthopedic effect of the brace

Excessively reducing the stiffness of the brace material will lead to the problem that the overall strength of the brace is not enough to perform orthopedics.

Moreover, long-term wearing of the brace may lead to muscle weakness, resulting in dependence on the brace

In addition, fixed braces can also cause joint contractures, hindering the normal movement of the spine
