Abstract

The invention relates to the technical field of medical apparatus, and discloses a spinal deformation correcting device. The spinal deformation correcting device comprises pedicle screws, a longitudinal connective bar, a bar presser, a locking nut, transverse connectors and a longitudinal connecting framework, wherein the screw bodies of the pedicle screws are implanted into a vertebral body of aspinal column to be corrected; the longitudinal connective bar is spliced with grooves of the pedicle screws; the bar presser is sleeved on the outer side of the pedicle screws; the locking nut is matched with internal threads of the pedicle screws; the transverse connectors are connected with tail pipes of two pedicle screws positioned on the same vertebral body; and a plurality of the transverse connectors positioned in the longitudinal direction of the spinal column are connected with one another through the longitudinal connecting framework. Besides, the invention also discloses a using method of the spinal deformation correcting device.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a spinal deformation correction device. The present invention also relates to a method for using the above-mentioned spinal deformation correction device. Background technique [0002] The surgical treatment of spinal deformity through spinal internal fixation technology has a history of several decades; from the adoption of spinal internal fixation technology in the 1980s in my country to the present, from the initial Harrington (Harrington rod) technology to the Luque cone plate under the steel wire in the 1970s Fixation, and then to CD (Cotrel-Dubousset) internal fixation system, spinal internal fixation technology has been greatly improved. In recent years, with the development of spinal biomechanics research and material science, spinal internal fixation technology has been widely used in the surgical treatment of spinal degenerative diseases, spinal tumors, trau...
