Spine coronal plane balance measuring scale

By designing a coronal plane balance measuring ruler for the spine and combining it with lumbosacral X-rays, the problem of judging coronal plane balance in spinal deformity surgery was solved by using the rotation and movement of the scale and vertical rod. This enabled accurate coronal plane balance measurement and improved the accuracy of the surgery.

AI Technical Summary

Technical Problem

In spinal deformity correction surgery, current technology makes it difficult to accurately determine the coronal plane balance, mainly because it is impossible to obtain full-length X-rays of the spine during the operation.

Method used

A spinal coronal plane balance measuring ruler was designed, including a scale, a horizontal bar, and a vertical bar. By combining intraoperative lumbosacral X-rays, the rotation and movement of the scale and the vertical bar can achieve accurate measurement of the patient's coronal plane balance.

Benefits of technology

It can accurately determine the coronal plane balance of the patient in the prone position during surgery, and grasp the changes in the coronal plane balance of the spine, thus improving the accuracy and reliability of the measurement.

Abstract

The utility model discloses a spine coronal plane balance measuring scale, which comprises a dial, a horizontal rod and a vertical rod, a rotating shaft is arranged in the center of the dial, the rotating shaft is fixedly connected with the dial, the vertical rod is sleeved on the rotating shaft and is in clearance fit with the rotating shaft, the vertical rod can rotate 360 degrees along the rotating shaft, the dial is provided with a through hole, and the horizontal rod is fixedly connected with the vertical rod. The horizontal rod penetrates through the through hole and is in clearance fit with the through hole, and the dial can transversely slide along the horizontal rod. The vertical rod can rotate around the rotating shaft, the dial can horizontally move along the horizontal rod together with the vertical rod, and the coronal plane balance of a patient in a prone position can be accurately measured and calculated by combining a C arm or X-ray fluoroscopy, so that the change condition of the coronal plane balance of the patient before and after correction is accurately mastered.
