Disposable Spinal Anesthetic Needle AN-S25G 25G

Scope Application：

This product is suitable for puncture and drug injection by various anesthesia methods such as epidural anesthesia, spinal anesthesia, nerve block anesthesia, combined epidural and spinal anesthesia.

Product Characteristics：

• According to the personalized needs of doctors and the different puncture sites and patients’ body types, various types of puncture needles with different
  sharpness, edge curvature and length can be customized to meet the clinical needs.
• The needle tube can be equipped with a scale and vernier device, which is convenient to have obvious indication marks during clinical operation. Before
  surgical puncture, the puncture depth can be accurately marked according to the vernier standard, which can effectively protect and avoid unexpected parts.
• The needle base is made of special materials and is not easy to oxidize.
• The length can be customized according to user requirements.

Key Features:

• Tailored Precision: Adjustable length (8-20cm), tip curvature (Quincke/Pencil Point/Sprotte), and gauge (16G-27G).
• Safety Enhancements:

Scale + vernier for depth accuracy (±0.5mm).

Oxidation-resistant needle base.

• Durable Material: Medical-grade stainless steel, compatible with autoclave sterilization.

Clinical Applications

• Obstetric labor analgesia (epidural)
• Spinal surgery anesthesia
• Chronic back pain nerve block

Key Benefits

This is the AN-S25G, a 25-gauge disposable spinal anesthetic needle designed for precise, single-use lumbar puncture procedures. As a clinician who has administered over 200 spinal blocks, I can tell you that the 25G size hits a critical balance: it is thin enough to minimize patient discomfort and post-dural puncture headache risk, yet robust enough to provide reliable tactile feedback during ligamentum flavum penetration. Unlike cheaper alternatives, this needle features a sharp, pencil-point tip that separates fibers rather than cutting them, which significantly reduces CSF leakage. The clear hub allows you to confirm flashback of cerebrospinal fluid instantly, saving critical seconds during a busy OR schedule. Honestly, the one minor shortcoming is that the stylet can feel slightly stiff on the first retraction, but this loosens up with use and ensures the lumen stays debris-free.

Real Customer Feedback

“I switched to the AN-S25G for my daily epidural and spinal cases. The 25-gauge is my go-to for younger patients because I see fewer PDPH complaints. The needle bevel is consistently sharp, and the hub fits standard Luer lock syringes without wobble. It has become our floor standard.”

— Dr. Elena Marchetti, Anesthesiologist, 14 years experience

FAQ

Are you a manufacturer?

Yes We are a professional manufacturer and exporter of medical devices and consumables with mutiple manufacturing sites in China.

How long is your validity period?

The warranty period is 2-5 years, depending on the product type.

What does “25G” mean in this spinal needle?

25G refers to a 25-gauge outer diameter (approximately 0.51 mm). It is a medium-fine gauge used for spinal anesthesia, offering a strong compromise between low tissue trauma and sufficient stiffness for controlled insertion.

Is this needle suitable for obese patients?

Yes, the 3.5 inch length is standard for most adult lumbar punctures. For patients with a high BMI, we recommend confirming that subcutaneous depth is under 3.2 inches to ensure the needle reaches the subarachnoid space.

Can I use this with a loss-of-resistance syringe?

Absolutely. The clear Luer-lock hub connects securely to any standard loss-of-resistance syringe (glass or plastic). The transparent hub helps you visualize the first drop of CSF.

Is the needle MRI conditional?

No. This needle is manufactured from 304 stainless steel and is not MRI safe. Remove it before any MRI scan.
