ETR

Bone biopsy disposable system composed by a four-sides sharp stylet, an ultra-sharpened cannula with side hole, a safety cap, a safety handle, an accessory wire to extract the sample and the special ETR cannula that avoids any painful deflecting operation. Standard shape handle.

Thanks to the special ETR cannula, the specimen collection is fast and harmless, without any painful deflecting operation. 

The Physician has just to rotate the needle to “trap” a full size and not damaged specimen.
