Stylet advance button remains locked during penetration: simpler manoeuvre, increased
safety during the biopsy procedure, enhanced sensibility upon penetration.
Pre-determinated bioptic throw (10-20 mm), adapting to the lesion size.
Stylet completely retractable from the cannula left in situ: control of the adequacy of the
specimen, possibility of multiple biopsies (prostate mapping).
Stronger mechanism: reliable cutting of the most compact tissue
