The through-hole having the greatest diameter for collecting or taking out the tissue sample is disposed as a collecting hole in the center of the needle body, and the though-holes having a diameter smaller than that of the central through-hole are disposed in the periphery. The through-holes are respectively used as a cutting hole for cutting the tissue sample, a treatment hole for infusing a disinfectant solution, a hole for administering a medicament for infusing a medicament for destroying cells having diseases, and an observation hole for observing an internal state for enabling more reliable collections. <P>COPYRIGHT: (C)2009,JPO&INPIT |
