A new aspiration-biopsy instrument for bone marrow was devised and experiences of clinical application were reported. 35 cases of bone marrow examination in hematological and nonhematological disorders involving 12 "dry tap" cases were studied. 68 trials of bone marrow biopsy on 35 cases were performed. Sufficient specimens were obtained in all cases. They were 2 mm in diameter and ranged from 0.3∼2.5 cm in length. (average length 1.2 cm). 66 out of 68 specimens (97%) were considered as good materials for histological evaluation except 2 specimens which were moderately crushed. The merits of a new aspiration-biopsy instrument were as follows:1. This needle were well evaluated not only for diagnosis of hematological and nonhematological disorders, but also for the study of haematopoietic activity and the staging of malignant lymphoma. By this method, cell and tissue examination could be performed simultaneously.2. As this method was being used for biopsy in the case of "dry tap", there was few damage on the patient's side.3. Having the stopper and the graduation attached to the complementary tube, this instrument could be used with safety.4. The outer needle was modeled according to the volume of old aspiration instrument.5. The outer needle was so easily removed that we could change it for another one, when damage of tip was found.6. The outer needle was able to being attached to the transfusion set, so that both infusions and blood transfusions could be carried out.
