This apical vertebra probe is suitable for UBE minimally invasive spinal surgery. Its ultra-slim long shaft easily accesses narrow intervertebral foramens and deep spinal canals. The corrugated anti-slip handle delivers stable grip, preventing slipping during slight rotation and pushing. It features a smooth blunt tip, specially designed to locate apical vertebra and explore the interior of spinal canals. The blunt end avoids lacerating the dural sac and nerve roots. It helps surgeons confirm vertebral position, detect spinal stenosis and define lesion scope during operations.
