Single Biopsy Extraction
For the single biopsy extraction, the ejection stylet is introduced and advanced into the distal opening of the outer cannula using an introducing aid. The sample can be extracted afterwards.
Multiple Biopsy Extraction
The use of a inner cannula with biopsy chamber for the multiple biopsy extraction is recommended. This cannula carrys during the penetration the sample and can be pulled out for the extraction, without changing the placement of the outer cannula.
