FIELD: biopsy instruments.
SUBSTANCE: device holds biopsy material in biopsy needle-cannula provided with fixing mechanism. Fixing mechanism is introduced into proximal end of biopsy needle-cannula, which end is pushed through between internal wall of biopsy cannula and cylindrical fragment of biopsy material. Distal end of fixing mechanism is provided with wire having cut. Wire has angle of preliminary shift, length, which length corresponds to biopsy cannula and ends up directly at its end. Device can be successfully used for performing through-skin biopsy of tissues, especially of solid tissue and marrow tissue.
EFFECT: improved efficiency.
