Spine orthopedic device

Abstract

The invention discloses a spine orthopedic device, which comprises a shoulder rest, a waist rest, a plurality of shape memory alloy bars, a power source and a controller, wherein the shape memory alloy bars are arranged between the shoulder rest and the waist rest in the longitudinal direction and electrically connected with the power source, and temperature sensors are arranged on the shape memory alloy bars and electrically connected with the power source controller. According to the relationship among current, temperature and deformation quantity of the nickel-titanium shape memory alloy, the deformation quantity of the shape memory alloy rod is automatically controlled by monitoring the temperature of the shape memory alloy rod; automatic correction of spinal deformity is achieved, andthe deformation quantity can be adjusted in time, so that orthopedic operation is more precise and accurate; in addition, power output can be automatically controlled according to stress of the shapememory alloy rod and physiological signals of a patient, and therefore high safety is achieved.

Description

technical field [0001] The invention relates to a spinal orthopedic device, which belongs to the field of medical instruments. Background technique [0002] Scoliosis is a common disease with an incidence rate of more than 5%, especially in adolescents and children. The deformity of the spine not only affects the normal growth and development, but also leads to the decline of cardiopulmonary function, inconvenient physical activities and even paralysis, and affects the mental health of patients. Cause serious harm, resulting in both physical and psychological disabilities. [0003] People have tried to use orthotics to correct scoliosis for a long time, but the curative effect of the old orthotics is not significant. With the emergence of modern orthotics such as Milwaukee, Lyon and elastic clothing, the orthopedic effect has been significantly improved, making more and more people More and more patients are choosing orthotics for spinal deformities. [0004] Since the dis...

AI Technical Summary

Problems solved by technology

However, the existing spinal orthopedic devices based on shape memory alloys are still in the initial stage of application and development, and there are still defects such as low intelligence and insensitive operation. It is necessary to develop a new spinal orthopedic device. The superelasticity of the alloy itself provides continuous orthopedic force. On the other hand, the deformation of the alloy can be intelligently controlled to provide dynamically adjustable orthopedic force, thereby improving the accuracy, sensitivity and curative effect of orthopedics.
