Problems solved by technology

Its shortcoming is that the vertebral body on one side is fixed on the correction rod with pedicle screws during correction, but the screws on the vertebral body on the other side of the curved spine cannot be fixed on the correction rod, and the operator needs to adjust it based on experience The other side of the vertebral body is corrected so that the screws on the vertebral body reach the position of the correction rod before the screw and the correction rod can be fixed. This requires extremely high surgical skills for the surgeon and there is a great risk of nerve damage during the operation. , requires precision, so the operation is a highly technically demanding operation

Abstract

The invention relates to a spine orthopedic device which comprises a first correcting part and a second correcting part, one end of the first correcting part is movably connected with one end of the second correcting part, and the first correcting part and the second correcting part are fixed to the two sides of the spine after apical vertebra osteotomy or resection at the spine bending position respectively. The first correcting part and / or the second correcting part are / is provided with a length adjusting part, and the length adjusting part is used for correcting the spine to the preset length when the first correcting part rotates relative to the second correcting part to correct the bent spine. By means of the spine orthopedic device, the spine bent in a V shape can be corrected and adjusted to the preset length. The invention further discloses an adjusting method of the spine orthopedic device.

Description

technical field [0001] The present invention relates to a spinal orthopedic device, and the present invention also relates to an adjustment method of the orthopedic device. Background technique [0002] Spinal correction uses methods including spinal osteotomy for orthodontic treatment. In the operation, the vertebral body of the top vertebra at the curvature of the spine is usually wedge-shaped osteotomy or total resection, and the deformed spine is usually corrected with correction rods, conventional correction rods In order to form the straight rod structure, the bending rod tool can be used to bend it during the operation to meet the morphological requirements of the surgeon, and it can be combined with the screws of the vertebral bodies on both sides to fix the spine. The disadvantage is that the vertebral body on one side is fixed on the correction rod with pedicle screws during correction, and the screw on the vertebral body on the other side of the curved spine canno...
