Quinke Biopsy Needle

Description

Quinke Biopsy Needle

The Quincke needle has a sharp, beveled cutting point and comes with a stylet. Clinicians use it for punctures and for aspiration of fluid.

Quincke needle: quincke point

The bevel cuts cleanly as it enters tissue. So the point passes with a light, controlled push. Also, you may see it spelled Quinke on our site, but the pattern stays the same.

The stylet

The stylet fills the lumen while you insert the shaft. That way, tissue stays out of the bore until you reach the target. Then you withdraw the stylet and attach a syringe to aspirate.

Diameters and lengths

Pick 0.7, 1.0 or 1.2 mm to set the bore. Meanwhile, the 76 mm and 89 mm lengths set the reach. Therefore, you can match both choices to the depth and the fluid you expect.

Picking a size

A finer Quincke needle makes a smaller entry point in the skin or tissue. However, a wider bore draws thicker fluid more easily. Because both factors matter, many teams keep more than one size in stock.

Reprocessing Quincke needle

Remove the stylet and flush the lumen at once. Next, wipe the bevel with care, since the point cuts easily through gloves. Finally, dry both parts, refit the stylet, and store the instrument with the tip covered.
