Spinal anesthesia needle AN-S

blunt22G18G

Combined Anesthesia Needle Sprotte Type (AN-S/S II) are spinal needles designed for atraumatic dural puncture and controlled directional flow of anesthetic agents. They feature a precision-formed lateral side hole, a lateral opening with fitted mandrel to prevent the biopsy effect, and a conical tip with no sharp edges to minimise post-spinal headache risk.

Key benefits

• Precision-formed side hole for directional flow of anesthetic agents and reduced risk of straddling the dura
• Special needle design with lateral opening and fitted mandrel to preclude the biopsy effect during puncture
• Conical needle tip with no sharp edges enabling atraumatic puncture of the dura and minimising risk of post-spinal headache
