A kind of spinal orthopedic bed with traction mechanism

technical field

The utility model relates to an orthopedic device, in particular to a spinal orthopedic bed with a traction mechanism.

Background technique

Scoliosis, also known as scoliosis, is a three-dimensional deformity of the spine, including sequence abnormalities in the coronal, sagittal and axial positions. The spine of a normal person should be straight when viewed from the back, and the sides of the trunk should be symmetrical. If a person has uneven shoulders from the front or uneven back from the back, he may suffer from "scoliosis". Scoliosis is diagnosed by taking a standing X-ray of the entire spine. If the front X-ray shows a lateral curvature of the spine greater than 10 degrees, scoliosis can be diagnosed. While the scoliosis of the spine is deformed, it may also be deformed to rotate in one direction or multiple directions, that is, the vertebral body may be deformed and diseased at various angles, resulting in deformed rotation of the spine. Scoliosis is a change in the physiological curvature of the spine due to a series of reasons such as congenital factors or acquired trauma, bad posture, etc., so that bending, hunchback or lateral spine deformation and deformity can be seen in appearance. If the scoliosis is severe, it may compress the important organs of the body such as the heart and lungs, causing a series of diseases in the body and shortening the life span of the patient.

Treatment methods for scoliosis include surgery, physical therapy, and exercise therapy. Among them, surgical treatment is only recommended for users with scoliosis above 40 degrees. It is risky and expensive. In addition, surgical treatment of scoliosis may damage nerves, leaving sequelae after surgery, changing body functions, and reducing cardiopulmonary function. ; For women, it may also affect reproductive function. Exercise therapy has a long cycle and slow effect, so it is one of the optional auxiliary therapies. Physiotherapy is a relatively safe and effective treatment for users with mild to moderate scoliosis. In physical therapy, appliances are used to fix the human body, and through certain methods, the appliance exerts an external force on the curved spine, so that the curved spine gradually returns to its original shape under the action of the external force. Thus, the design of the physical appliance is critical.

The existing spinal orthopedic bed is not suitable for users who need to position the limbs, such as leg fractures, or other diseases that require suspension traction.
