Description

Three-dimensional orthopedic brace

Technical Field

The utility model relates to the technical field of medical equipment, especially, relate to a three-dimensional orthopedic brace of individuation customization.

Background

Spinal deformities are three-dimensional deformities characterized by coronal plane deviation, sagittal plane imbalance, and transverse rotation, and may also be considered a four-dimensional deformity in view of their progression over time. Wherein adolescent idiopathic scoliosis is the most common, the prevalence rate is 0.47-5.20%, female patients are common, and the onset age of 90% of patients is 11-18 years. Adolescent idiopathic scoliosis progresses rapidly in adolescence, and the probability that the difference actually exists is 95% when the difference value of the Cobb angle is 5 degrees reported in the literature, which indicates that the deformity progresses. The change of the physical appearance of the patient can influence the self-evaluation and psychological confidence of the patient, and the serious patient can also influence the balance of the cardiopulmonary function and the body, thereby reducing the life quality. With the deep understanding of the pathophysiology and clinical treatment and the development and progress of the spinal column orthopedic technology and the internal fixation instrument, the brace treatment is suitable for mild and moderate patients (such as patients with 20 degrees Cobb angle)

45 deg.) that the surgical treatment is appropriate for progressive or severe malformed patients has reached consensus. The scoliosis correction brace is worn, so that the progress of the state of an illness can be effectively slowed and controlled.

The current scoliosis correction brace is designed by medical personnel according to experience, the brace mainly adopts computer aided design, 3D printing is adopted, few braces based on the mechanics analysis design of a spine three-dimensional finite element model are available, and the brace is only simply pasted by magic in a pressurizing mode and needs to be given one by one, pressurizing force is not objective, a pressure sensor is not installed, monitoring is impossible, human errors inevitably occur, the situation that the brace is too loose or too tight occurs, not only is the use experience reduced, but also the correction effect is influenced, and even the illness state is aggravated. Specifically, if the brace is too tight, the brace is excessively squeezed, so that the skin is broken and infected, the life quality of a patient is seriously affected, if the brace is too loose, the brace cannot play a role in correction, and as teenagers are in the growth and development period, the brace is usually rechecked regularly for 8 months or 1 year after the braces are worn, once the brace is too tight in the period, the brace cannot be timely found, manpower and material resources are wasted, the expected correction purpose cannot be achieved, and improvement is urgently needed.
