What is the diameter range for non-vascular needles?

The diameter range for non-vascular needles typically falls between 22 gauge to 14 gauge. This range is commonly used in various medical procedures, including interventional radiology, where non-vascular needles are employed for purposes such as biopsy sampling, drainage procedures, and certain types of injections.

Needle gauges indicate their diameter, with lower numbers corresponding to larger diameters. For example, a 14 gauge needle is considerably larger than a 22 gauge needle, making the 14 gauge suitable for applications where larger volumes of fluid need to be drawn or administered.

Using non-vascular needles within the 22 to 14 gauge range provides a balance, offering sufficient size for clinical applications while incorporating the precision needed for procedures that require careful placement without causing unnecessary trauma to surrounding tissues. This range is extensively utilized in practice, aligning with standard protocols in interventional procedures.
