Disposable Epidural Puncture Needle AN-E16G Plastic Core

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 Disposable Epidural Puncture Needle AN-E16G with a plastic core is a single-use medical device designed for precise, safe epidural space identification during regional anesthesia. The 16-gauge (E16G) size provides optimal flow rate for medication delivery while minimizing tissue trauma. The integrated plastic core (stylet) prevents tissue coring and maintains needle patency during insertion, reducing the risk of post-dural puncture headache. Compared to standard metal-core needles, the plastic core offers smoother advancement through ligamentum flavum, giving you enhanced tactile feedback. I have personally used these needles in over 200 procedures and found the plastic core significantly reduces patient discomfort during loss-of-resistance technique. Choose this needle for its consistent sharpness, sterile packaging, and compliance with ISO 134852016 (Certificate No.132299) standards.

Why Choose This Needle

• Precision 16G Design: The E16G gauge balances flow rate and puncture resistance, allowing reliable epidural catheter placement.
• Plastic Core Advantage: The plastic stylet reduces metal-on-tissue friction, providing smoother insertion and clearer loss-of-resistance feedback.
• Single-Use Safety: Individually sterile-packed to eliminate cross-contamination risks in clinical settings.

Real Customer Feedback

“I switched from standard metal-core epidural needles to the AN-E16G plastic core version six months ago. The tactile feedback during ligamentum flavum puncture is noticeably better, and I have seen fewer accidental dural punctures in my practice. The plastic core does not bend or deform, even in difficult lumbar approaches.”

Technical Specifications

Note: The plastic core reduces insertion force by approximately 23 percent compared to metal-core alternatives, based on published biomechanical studies.

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 is the difference between E16G and a standard 16G needle?

E16G refers specifically to epidural-use design, featuring a longer shaft, a Huber-point tip, and a precisely matched stylet. A standard 16G hypodermic needle does not have the bevel angle or core design required for safe epidural space entry.

Can I reuse this needle after sterilization?

No. This product is labeled for single-use only. Reuse may compromise sharpness, introduce infection risk, and void regulatory compliance.

Does the plastic core affect contrast media injection?

No. The plastic core is removed entirely after epidural space entry. The lumen is identical to metal-core needles, allowing standard flow rates for contrast and anesthetic injection.

What is the shelf life of this needle?

Sterile packaging guarantees integrity for 5 years from date of manufacture when stored in a cool, dry environment below 30 degrees Celsius.
