Abstract
Embodiments of assemblies used for bending spinal needles and method for producing bent spinal needles used in medical procedures are disclosed. In one embodiment, a straight needle is placed in position for a fulcrum to apply pressure onto a designated spot on the needle and apply a bending pressure to bend the needle while the needle is supported at both ends. A barrier wall is configured to limit the movement of the needle resulting from the bending force to prevent overbending of the needle. In two other embodiments, a dual angle bending member enables selecting the bending angle desired by the user to be applied onto the needle. The angle of the bent needle is considerably reduced due to metal relaxation; however, the angle reduction is predictable and is taken into account in calculating the target bending angle.
