The first percutaneous needle can have a first lumen and a proximal end and a distal end within the epidural space that is at least one level away from the target lamina. Arranged at the first position. The second percutaneous needle can have a second lumen and a proximal end and a distal end, the distal end of which is within the epidural space one level away from the target lamina. 2 is arranged. The light tracking tool can be coaxially movable within one of the first and second lumens. The grasping tool is coaxially movable within the other of the first and second lumens, emits light, retracts the light tracking tool, and / or is temporarily connected within the epidural space of the target lamina. can do.
