FAQ:
Q1: What specific medical procedures are 21G interventional needles primarily used for?
A: They are widely used in coronary angiography, peripheral angiography, cerebral angiography catheter guidance, as well as puncture biopsies and abscess drainage of solid organs such as the kidneys and liver. Their fine characteristics make them particularly suitable for minimally invasive surgeries in elderly patients or those with poor vascular conditions requiring high imaging resolution.
Q2: What is the clinical significance of the side hole design on this needle?
A: The side hole design effectively disperses the impact force of fluid jets, preventing intimal stripping or rupture of small vessels during high-pressure contrast injection. In biopsy applications, it also ensures uniform distribution of negative pressure during aspiration, improving the success rate of obtaining tissue samples while minimizing damage to normal tissue.
Q3: Does the green Luer lock hub conform to international general standards?
A: Yes, our products strictly comply with international medical device industry standards (such as ISO 80369 series). In most standards, the 21G gauge commonly uses green as its identifying color. This helps medical staff quickly confirm the instrument size in fast-paced surgical environments, avoiding confusion and improving surgical efficiency.
Q4: What are the main performance differences between 21G and 20G puncture needles?
A: The 20G needle has a larger inner diameter and higher fluid throughput, making it suitable for complex lesions requiring rapid, large-volume contrast media; while the 21G needle is finer, causing less trauma and providing a clearer imaging path, making it ideal for routine diagnostic angiography or delicate surgeries with extremely high vascular protection requirements. The choice depends on the specific surgical needs and the patient's vascular condition.
