Description
The Avanos 18369 (formerly Halyard/Kimberly-Clark) is a Chiba-Style Spinal Needle. This needle is highly regarded for its precision and tactile feedback, making it a standard choice for both diagnostic and therapeutic spinal procedures.
The model number specifies its dimensions: 22 Gauge thickness and 3.5 inches (90 mm) in length.
Key Features
Chiba-Style Tip: Features a short bevel design. The 30-degree angle of the Chiba tip provides the clinician with enhanced tactile sensitivity, allowing them to accurately "feel" the needle passing through the ligamentum flavum and the dura mater.
Regular Wall Construction: Manufactured with medical-grade stainless steel with a standard wall thickness, providing the rigidity needed to maintain a straight path through dense ligaments while resisting bending.
Translucent Plastic Hub: The hub is color-coded Black (standard for 22G). Its translucent design allows for immediate visualization of cerebrospinal fluid (CSF) or blood "flashback," confirming successful entry into the target space.
Integrated Metal Stylet: Includes a precisely fitted stylet that prevents tissue "coring" (the accidental removal of a small skin or tissue plug) during insertion, ensuring the needle lumen remains unobstructed for medication delivery or fluid collection.
Depth Indicator: Often equipped with a sliding rubber depth indicator on the shaft to help the clinician monitor insertion depth according to pre-procedural imaging.

Primary Uses
Diagnostic Lumbar Puncture: A primary tool for collecting cerebrospinal fluid (CSF) for laboratory analysis to detect conditions like meningitis, subarachnoid hemorrhage, or neurological disorders.
Myelography: Used to inject contrast media into the subarachnoid space for radiographic imaging of the spinal canal.
Spinal Anesthesia: Facilitates the delivery of anesthetic or analgesic agents into the spinal fluid for surgical procedures.
Pressure Measurements: Used in conjunction with a manometer to measure the "opening pressure" of the CSF during a diagnostic tap.
