FAQ:

Q1: What is a 20G interventional needle? In which medical fields is it mainly used?

A:​ A 20G interventional needle refers to a medical puncture needle with a 20-gauge standard diameter (inner diameter approx. 0.6mm-0.9mm, depending on specific tolerances). It is widely used in interventional radiology, angiography, CT-guided biopsy, abscess drainage, and local medicine perfusion.

Q2: Why does this needle feature a side hole design? How does this help in surgery?

A:​ The side hole design allows fluids (such as contrast agents or medications) to flow out more uniformly and smoothly, preventing excessive pressure at the tip that could damage blood vessel walls or surrounding tissues. This is particularly important for interventional surgeries requiring precise control over flow rate and direction, such as cardiac angiography or tumor chemotherapy perfusion.

Q3: Besides aesthetics, what is the practical function of the yellow hub?

A:​ The medical industry often uses a color-coding system to quickly differentiate needle gauges. The standard color corresponding to 20G is typically yellow. This not only allows medical staff to quickly confirm the needle gauge to avoid errors but also improves the efficiency of medication preparation and operation in emergencies.

Q4: Can this interventional needle be reused?

A:​ We recommend this product as a single-use medical consumable. To ensure optimal puncture performance and strict sterilization standards, single-use helps avoid cross-contamination risks and ensures the sharpness of every puncture.
