Description
The Avanos 18397 (formerly Halyard/Kimberly-Clark) is an Extra-Long Quincke-Style Spinal Needle. It is a specialized medical device used primarily for spinal anesthesia or diagnostic lumbar punctures in clinical scenarios where standard-length needles cannot reach the target space.
The model number specifies its dimensions: 22 Gauge thickness and 6 inches (152 mm) in length.
Key Features
Extra-Long 6-Inch Reach: At 15.2 cm, this needle is nearly twice the length of a standard 3.5-inch spinal needle. It is specifically designed for patients with a large body habitus (high BMI/obesity) or unique anatomical variations where the subarachnoid space is deep.
Quincke-Style Bevel: Features a traditional "cutting" tip with a medium-length bevel. This tip design provides clinicians with high tactile feedback, allowing them to feel the distinct "pop" as the needle penetrates the ligamentum flavum and the dura mater.
Sliding Depth Indicator: Most versions of this long needle include a rubber depth stopper on the shaft. This allows the clinician to pre-set or track the insertion depth based on pre-procedural imaging (Fluoroscopy or CT), significantly enhancing safety during deep access.
Integrated Metal Stylet: Comes with a precisely fitted metal stylet that prevents "coring" (the removal of a small skin or tissue plug) during insertion. This ensures the needle lumen remains unobstructed for fluid aspiration or drug delivery.
Translucent Hub: The hub is color-coded Black (standard for 22G) and translucent, allowing for immediate visualization of cerebrospinal fluid (CSF) or blood "flashback."

Primary Uses
Diagnostic Lumbar Puncture in Obese Patients: Used to collect CSF for laboratory analysis when standard 3.5-inch or 5-inch needles are insufficient.
Myelography: Facilitates the injection of contrast media into the spinal canal for imaging in patients with deep anatomical targets.
Deep Spinal Anesthesia: Used to deliver anesthetic agents for surgery in patients where the spinal canal is located deeper than 10-12 cm from the skin surface.
Pressure Monitoring: Allows for the measurement of CSF opening pressure in challenging anatomy.
