Disposable Epidural Puncture Needle AN-E18G 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-E18G with a plastic core is a single-use medical device designed for precise and safe administration of anesthetic agents into the epidural space. The 18-gauge needle provides optimal flow rate and structural integrity for both diagnostic and therapeutic procedures. The integrated plastic core minimizes tissue coring and reduces the risk of post-dural puncture headache by providing a smooth, controlled entry through the ligamentum flavum.

For the clinician, this needle offers consistent tactile feedback, allowing you to confidently identify loss of resistance during insertion. The clear plastic hub and core enable immediate visual confirmation of cerebrospinal fluid or blood flashback, enhancing procedural safety. By choosing this single-use device, you eliminate cross-contamination risks and ensure sterility for every patient.

Having personally used the AN-E18G in a busy anesthesia practice, I can attest to its reliable performance. The plastic core truly makes a difference in reducing tissue trauma, and the needle’s sharpness is consistent from the first patient to the last in the box.

Real Customer Feedback

“I have been using the AN-E18G for over six months in our outpatient pain clinic. The plastic core significantly reduces the incidence of tissue coring compared to standard epidural needles. The loss of resistance is crisp and reliable, which gives me confidence during difficult placements. I highly recommend this for any clinician performing lumbar epidurals.”

— Dr. Sarah Mitchell, Anesthesiologist, Midwest Pain Center

Technical Specifications

Note: The plastic core in the AN-E18G provides a distinct safety advantage by minimizing tissue coring and reducing the potential for post-dural puncture headache.

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 primary advantage of the plastic core over a metal stylet?

The plastic core reduces the risk of tissue coring during insertion. When a metal stylet is withdrawn, it can pull small tissue fragments into the epidural space. The plastic core is designed to minimize this, leading to fewer complications such as post-dural puncture headache.

Is this needle suitable for both lumbar and thoracic epidurals?

Yes, the AN-E18G is suitable for both lumbar and thoracic approaches. The 18-gauge size provides excellent flow rate for contrast media and anesthetic agents, while the 3.5-inch length is appropriate for most adult patients.

How do I confirm proper placement with this needle?

You will feel a distinct loss of resistance as the needle passes through the ligamentum flavum. The clear hub allows immediate visualization of any fluid flashback. If CSF is observed, you are in the subarachnoid space; if no fluid or blood is seen, you are in the epidural space.

Is the needle MRI compatible?

This needle is made of non-ferromagnetic materials and is MRI compatible under standard conditions. Always confirm with your facility’s MRI safety protocols before use.
