Spinal Needle Explained: Types, Sizes, and Common Uses
From anesthesiologists to neurologists, the spinal needle is a tool they rely on every day—and choosing the right one can make all the difference.
🔍 What Is a Spinal Needle Used For?
1. Spinal Anesthesia
One of the most common applications of a spinal needle is in regional anesthesia. It delivers anesthetic directly into the cerebrospinal fluid, numbing the lower part of the body during surgeries.
2. Diagnostic Spinal Tap
Also known as a lumbar puncture, this procedure uses a spinal tap needle to collect cerebrospinal fluid (CSF) for testing. It's vital in diagnosing infections, bleeding, or neurological conditions.
3. Intrathecal Injections
Used to administer chemotherapy or pain medication directly into the CSF.
Understanding Spinal Needle Sizes and Gauges
What Is Spinal Needle Gauge?
Gauge refers to the diameter of the needle. The higher the gauge, the thinner the needle.
Choosing the correct spinal needle size depends on the patient's age, the purpose of the procedure, and the desired flow rate.
Spinal Needle Types You Should Know
1. Quincke Needle (Cutting Tip)
This traditional needle has a sharp bevel that slices through tissues. Commonly used in diagnostic spinal taps.
2. Whitacre Needle (Pencil-Point Tip)
A type of atraumatic spinal needle designed to spread rather than cut tissues. It's popular for spinal anesthesia because it reduces the risk of post-lumbar puncture headache.
3. Sprotte Needle
Similar to the Whitacre but with a longer opening. Favored in obstetric anesthesia.
4. Tuohy Needle
Used more for epidural anesthesia, but still worth noting in the context of regional procedures.
Key Parts of a Spinal Needle
Hub – Connects to the syringe.
Cannula – The main hollow shaft of the needle.
Stylet – Prevents tissue blockage inside the needle during insertion.
Bevel/Tip – Determines whether it’s cutting or non-cutting.
Understanding spinal needle parts helps in selecting the right type for your procedure and improving patient outcomes.
Choosing the Right Spinal Needle: Tips for Practitioners
When selecting a spinal needle, consider:
Gauge size (thinner needles = less patient discomfort)
Length (based on patient’s body size)
Tip design (atraumatic vs. cutting)
Compatibility with syringes or other devices
Sterility (ensure it’s a disposable spinal needle if single-use)

FAQs
1. What is the difference between an atraumatic spinal needle and a regular one?
An atraumatic needle has a blunt pencil-point tip that parts the tissue instead of cutting it, reducing complications like post-dural puncture headache.
2. What gauge is typically used for spinal anesthesia?
A 22G or 25G needle is commonly used. The higher the gauge, the thinner the needle, which typically results in less discomfort.
3. Can I reuse a disposable spinal needle?
No. Disposable spinal needles are meant for single use only to prevent infection and maintain sterility.
4. Why is the stylet important in a spinal needle?
The stylet prevents tissue from clogging the needle during insertion, which helps maintain patency.
5. What certifications should a good spinal needle manufacturer have?
Look for ISO 13485, CE marking, and FDA clearance to ensure global standards are met.
