The UNLUX SYSTEM™ needle allows users to perform bone marrow biopsies on the iliac crest. With this particular system, it is possible to avoid the dislocation manoeuvre when the sample is being withdrawn. Due to its particular features, specific technical aspects of this device have been patented.


  • The “Trocar” tip stylet guarantees fast and non-traumatic penetration.
  • The ergonomic handle improves grip and the precision of the biopsy operation.
  • With the universal Luer-Lock connector, any syringe can be connected.
  • The ultra-sharp crown tip of the cannula facilitates the removal of an intact bone marrow fragment.


  1. Insert the needle, with a stylet, perpendicular to the bone surface. Progress forward by rotating the needle to the right and left. When the resistance decreases, the medullary cavity has been entered.
  2. Remove the stylet and advance into the medullary cavity for about 2 cm.
  3. Insert the UNLUX SYSTEM™ cannula and rotate the entire device 360° twice, cutting a fragment of bone marrow tissue from the distal part, without damaging it and avoiding its dislocation.
  4. Extract the entire cannula needle UNLUX SYSTEM™ – stylet from the patient.
  5. Remove the UNLUX SYSTEM™ stylet from the cannula. To deposit the sample on the microscope slide, insert the finger protection device and the extractor in the opposite side from the needle handle.
