A biopsy needle set (200, 200') for minimally invasive removal of tissue samples is described, with a first needle (210, 210', 220, 220', 230, 230') which comprises a hollow shaft, a holding area (211, 211', 221, 221', 231, 231') and a distal end (212, 212', 222, 222', 232, 232') opposite the holding area (211, 211', 221, 221', 231, 231'), and with a second needle (220, 220') which is arranged to be able to move to and fro in the hollow shaft of the first needle (210, 210') and comprises a holding area (211, 211', 221, 221', 231, 231') and a distal end (212, 212', 222, 222', 232, 232') opposite the holding area (211, 211', 221, 221', 231, 231'), and which second needle (220, 220'), in the area of its distal end (222, 222'), is divided lengthwise into at least two needle halves. The biopsy needle set (200, 200') is characterized by a third needle (230, 230') which has a holding area (231, 231') and a distal end (232, 232') opposite the holding area, wherein the second needle (220, 220') has a hollow shaft for receiving the third needle (230, 230'), and both needles (220, 220', 230, 230') are arranged to be able to move to and fro relative to one another. An injector apparatus (100, 300) for such a biopsy needle set (200, 200') and a biopsy device are also described. |
