Key Benefits

This is the AN-S18G Disposable Spinal Anesthetic Needle, a 18-gauge precision instrument designed for single-use lumbar puncture and spinal anesthesia administration. It provides a sharp, consistent puncture with minimal tissue trauma, ensuring a smooth procedure for the clinician and reduced discomfort for the patient. Why choose this? Because it combines a rigid 18-gauge construction with a sterile, ready-to-use design that eliminates cross-contamination risks, saving you preparation time in high-volume clinical settings.

Precision and Safety

• 18-Gauge Rigidity: The larger bore provides excellent tactile feedback and steady flow for contrast media or anesthetic agents, giving you confident control during dural puncture.
• Disposable Sterility: Each needle is individually packaged and gamma-sterilized, eliminating the need for reprocessing and reducing infection risks.
• Sharp Quincke Tip: A beveled cutting edge ensures a clean dural incision, facilitating faster CSF flow and shorter procedure time.

User Experience

• Clear Hub Design: The transparent polypropylene hub allows immediate visualization of CSF flashback, confirming correct placement.
• Color-Coded Gauge: The standard yellow hub color instantly identifies the 18G size, preventing mix-ups during rapid setup.

Real Customer Feedback

“I’ve been using these AN-S18G needles in our outpatient pain clinic for six months. The 18-gauge is perfect for heavier contrast media injections, and I haven’t had a single hub crack or needle bend. Honestly, the packaging is a bit bulky for our small supply cart, but the performance is rock-solid.”
— Dr. Maria Chen, Anesthesiologist, Pacific Spine Center
