Description

An orthopedic implantable adjustable bending plate for scoliosis surgery

This application is a divisional application for an invention patent application with the application number: 2018102895090, the name of invention and creation: an implantable scoliosis surgery auxiliary adjustable bending plate, and the application date: April 3, 2018.

technical field

The invention relates to the technical field of medical devices, in particular to an orthopedic implantable scoliosis surgery auxiliary adjustable bending plate.

Background technique

Scoliosis, also known as scoliosis, is a three-dimensional deformity of the spine, including coronal, sagittal, and axial sequence abnormalities. The spine of a normal person should be a straight line from the back, and the two sides of the torso should be symmetrical. If the shoulders are unequal in height from the front or the back is uneven from the back, it should be suspected of "scoliosis". At this time, a standing full spine X-ray should be taken. If the frontal X-ray shows a lateral curvature of the spine greater than 10 degrees, scoliosis can be diagnosed. Mild forms of scoliosis are usually without significant discomfort and no apparent physical deformity. Severe scoliosis will affect the growth and development of infants and adolescents, deform the body, and in severe cases can affect cardiopulmonary function, and even involve the spinal cord, resulting in paralysis. Mild scoliosis can be observed, and severe cases require surgical treatment. Scoliosis is a common disease that endangers adolescents and children. The key is to detect and treat early.

In the early stage of scoliosis, if the degree of curvature is not serious, external correction can be performed. Once the curvature is greater than 45︒, scoliosis surgery should be performed as soon as possible for correction. Scoliosis surgery is to straighten and fix the deformed spine. It is quite intensive. Traditional correction surgery uses surgical forceps to straighten the correction device. Once the angle is not well grasped, it is easy to touch the nerve, which increases the risk of surgery.
