Abstract

This utility model discloses a thoracic spine protective brace, including a neck support and a chest support arranged vertically. The chest support includes a front chest support and a back support arranged front to back, with a telescopic component between the front chest support and the neck support, and between the back support and the neck support. Through the combined use of the neck support and the chest support, it can be used for patients with impaired stability in the thoracic vertebrae 1-4, including those with trauma and thoracic spine surgery. The purpose is to maintain spinal stability during rehabilitation, improve spinal load-bearing capacity, promote patient comfort, enhance psychological support for patients with motion sickness, and encourage appropriate activity. The telescopic component, in conjunction with a third connecting strap, makes this thoracic spine protective brace suitable for patients of different body types. When the inner plate is adjusted to the desired position, a snap-fit mechanism quickly limits the movement between the outer shell and the inner plate, effectively ensuring the accuracy of the telescopic component's height adjustment.
