Document Type and Number:
Japanese Patent JP2019136497
Kind Code:
A
Abstract:
To provide a spinal repositioning instrument and a spinal repositioning system enabling a correction with less displacement in anterior-posterior direction applied to a vertebral body.SOLUTION: A spinal repositioning instrument 1 is disclosed, including a first coupling body 10 for direct or indirect coupling to a pedicle screw, and a second coupling body 20 for direct or indirect coupling to another pedicle screw. The spinal repositioning instrument 1 is configured to perform a first movement and a second movement independent from the first movement. Under the first movement, the coupling bodies perform a scissor-like pivoting about a first axis. Under the second movement, the coupling bodies rotate in opposite directions about respective second axes. The second axes are relatively fixed under the second movement. The spinal repositioning instrument 1 further includes a synchronizing transmission configured such that the rotations of the coupling bodies under the second movement are mirror symmetrical to each other.SELECTED DRAWING: Figure 2
