1. A device for marking a path on a skin surface for inserting an epidural needle into an epidural space, the device comprising:
a first arm having a length extending between a proximal end and a distal end, and a first plurality of holes equally spaced apart by a fixed distance along the length of the first arm;
a pin attached at the proximal end of the first arm, wherein the pin is a hollow cylinder made from a material that is visible in fluoroscopy imaging for providing a fixed reference point that identifies a selected target location in the epidural space; and
a second arm having a proximal end attached to the pin allowing the first and second arms to rotate about the pin to adjust an angle separating the first and second arms, and further having a length extending from the proximal end to a distal end, and a second plurality of holes equally spaced apart by the fixed distance along the length of the second arm;
wherein the first and second pluralities of holes on the first and second arms provide locations for marking the path on the skin surface to insert the epidural needle; and
wherein the first and second arms include the material surrounding each hole of the first and second pluralities of holes causing the first and second pluralities of holes to visually depict a path in the fluoroscopy imaging for inserting the epidural needle to reach the selected target location identified by the pin.
