Description
he Avanos 183172 is a specialized Discogram Set (also known as a Double Needle Set). This medical device is engineered for "needle-through-needle" access to the spinal discs, providing the length and stability required for provocative discography or deep-tissue spinal injections.
Key Features
Double Needle System: Designed so a fine-gauge inner needle (spinal) is guided through a larger-gauge outer needle (introducer). This allows for deep penetration with a thin final needle while minimizing "needle whip" or bending.
Short Bevel Tip: The primary spinal needle features a short bevel tip. This design is preferred for discography as it provides enhanced tactile feedback when penetrating the annulus fibrosus and reduces the risk of over-penetration.
Precision-Matched Lengths: The introducer and spinal needle are specifically matched in length so the inner needle extends exactly the intended distance beyond the introducer tip.
Fitted Metal Stylets: Both needles are equipped with fitted metal stylets to prevent tissue coring and to maintain the structural integrity of the needles during insertion.
Clear Plastic Hubs: The hubs are made of clear plastic to allow the clinician to immediately visualize any fluid flashback.

Primary Uses
Provocative Discography: The primary diagnostic use. A clinician uses the set to inject contrast media into the nucleus pulposus of an intervertebral disc to determine if that specific disc is the source of the patient's chronic back pain.
Deep Access Nerve Blocks: Used when a standard 3.5-inch needle is too short to reach specific deep-seated nerve structures.
Diagnostic Spinal Imaging: Facilitates the injection of dyes or contrast agents into deep spinal layers where high precision and stability are required.
