Description

Technical Field

[0001] The utility model relates to medical equipment, in particular to a scoliosis correction measuring device during surgery. Background Art

[0002] Scoliosis, commonly known as scoliosis, is a three-dimensional deformity of the spine, including abnormal sequences in the coronal, sagittal and axial planes. Severe scoliosis can affect cardiopulmonary function and even involve the spinal cord, causing lower limb dysfunction or even paralysis. The use of three-dimensional correction technology and pedicle screw fixation surgery is the only effective treatment. However, excessive correction of scoliosis during surgery can easily lead to failure of internal fixation devices, increase the incidence of surgical complications, and even cause nerve damage and paralysis. Insufficient correction cannot change the spinal sequence and it is difficult to achieve an effective treatment effect. Therefore, it is particularly important to judge the correction angle in real time during surgery. Therefore, it is necessary to design an intraoperative scoliosis correction measurement device to judge whether the correction is appropriate during surgery, so as to avoid the above problems.
