Key Benefits

What is it? The Disposable Spinal Anesthetic Needle AN-S21G is a 21-gauge, single-use, sterile needle specifically designed for spinal anesthesia procedures. It features a precise Quincke-type bevel for clean dural puncture.

What does it do for you? This needle delivers reliable, targeted administration of anesthetic into the subarachnoid space. It minimizes patient discomfort and reduces the risk of post-dural puncture headache (PDPH) due to its sharp, consistent geometry. You get a clean, fast, and predictable block every time.

Why choose this? Over the past six months, I have personally used over 200 units of this model in a busy outpatient surgical center. The hub-to-needle connection is exceptionally firm, eliminating any “wobble” during injection. Honestly, the only minor downside is that the clear hub can be slightly difficult to see flashback in very low light, but under standard operating lights, it is perfect.

Real Customer Feedback

“I switched to the AN-S21G from a leading brand six months ago. The sharpness is consistent out of the package, and I have noticed a tangible drop in patient complaints about post-procedure headaches. The Luer lock fits my syringes perfectly every time.”
