The BEST-LISAS® bone marrow biopsy needles with the NOLOSE® system feature an internal sample collection mechanism that ensures a successful and intact sample retrieval. The minimally invasive technique and the absence of bone dislocation make the procedure less painful for patients and simpler and quicker for the operator. The optimized geometry of the needle opening (TREPAN® geometry) allows for the collection of intact samples with a significantly larger volume compared to conventional Jamshidi needle systems, while reducing trauma during needle insertion. The ergonomic handle, with color coding, ensures precise and controlled operation and makes it easy to identify the needle sizes (gauge).
