Abstract
The invention relates to a biopsy needle for obtaining material for histological examination of body tissue, in particular, of bone marrow, or for the isolation, culture and modification of body cells, comprising a cannula with a cutting edge and a manual turning handle and a stylet running in the cannula. At the end of the cannula is an internal thread and preferably an outer thread. An easily visible marking is preferably provided on the manual turning handle. On withdrawing the biopsy needle the biopsy sample is thus held in position in the cannula and the advancing is precisely controllable.
