Intraoperative correction device for scoliosis

Abstract

The invention relates to an intraoperative correction device for scoliosis. The intraoperative correction device comprises two cross bars arranged at two ends and parallel to each other and longitudinal connecting bars with adjustable length and located above the cross bars. The cross bars are perpendicular to the longitudinal connecting bars. When surgical correction is performed, a current position of a spine can be accurately determined, when a linear light spot coincides with the position of the spine, the purpose of correction is achieved, and the effects of equal height of postoperativeshoulders and balanced spine sagittal position are achieved.

Description

technical field [0001] The invention relates to the field of surgical instruments, in particular to a scoliosis intraoperative correction device. Background technique [0002] The spine is the central axis skeleton of the human body, the pillar of the body, and has functions such as weight bearing, shock absorption, protection and movement. A normal person's spine is straight when viewed from the back or front. If the spine deviates from this central axis to the left or right, causing the spine to curve sideways into a "C" or "S" shape, it is called scoliosis. Scoliosis is one of the most common diseases of spinal deformity, with an incidence rate as high as 0.5%-3%. There are an estimated 12 million patients worldwide, and at least more than 3 million people in China. [0003] Posterior orthopedic surgery is a classic way to treat scoliosis. The key to posterior orthopedic surgery is to correct the patient’s spinal deformity while restoring the coronal and sagittal plane ...

AI Technical Summary

Problems solved by technology

[0005] 1. During the operation, it is necessary to place the measuring instrument on the top of the spine for measurement, stop the operation, and then remove the measuring instrument after the measurement is completed. If there is a problem, it is necessary to re-adjust the operation. Due to the limitation of the operating environment, the above operation is particularly inconvenient;

[0006] 2. A protractor is required during the measurement process, and the accuracy is poor. The most important thing is that the orthopedic angle of the orthopedic surgery cannot be measured in real time, which increases the surgical risk of repeated measurement and adjustment;

[0007] 3. Since the length of the measuring rod needs to be long enough to measure the entire spine at one time, it will inevitably be deformed during the measurement process, which will affect the measurement accuracy and affect the surgical effect
