As for the biopsy equipment, in the driver assembly and the aforementioned driver assembly which are kept by the user it has with the disposable biopsy probe assembly which installation and removal possibly is installed. The aforementioned driver assembly generates the fluid flow of the vacuum which faces to absorption source, at the same time, is constituted by a state where the fluid flow of the positive pressure which leaves from the aforementioned absorption source is prevented, has the 1st absorption route which possesses the 1st check valve which is arranged. The aforementioned disposable biopsy probe assembly generates the fluid flow of the aforementioned vacuum from the sample basket, at the same time, is constituted by a state where the fluid flow of the aforementioned positive pressure which faces to the aforementioned sample basket multiplex is prevented, has the 2nd absorption route which possesses the 2nd check valve which is arranged. For example the flow to the aforementioned absorption source is prevented from the aforementioned sample basket of the vital substance of the biopsy where with a certain execution form, the fluid management tank is arranged fluid in the aforementioned 2nd absorption route, remains behind.< Selective figure >Figure 3生検機器は、ユーザーによって保持されるドライバアセンブリと、前記ドライバアセンブリに着脱可能に取付けられる使い捨ての生検プローブアセンブリとを備える。前記ドライバアセンブリは、吸引源に向かう負圧の流体流れを発生させ、かつ、前記吸引源から離れる正圧の流体流れを防止する状態に構成され、配置されている第1の逆止め弁を有する第1の吸引経路を備える。前記使い捨ての生検プローブアセンブリは、サンプルバスケットから前記負圧の流体流れを発生させ、かつ、多重的に前記サンプルバスケットへ向かう前記正圧の流体流れを防止する状態に構成され、配置されている第2の逆止め弁を有する第2の吸引経路を備える。例えばある実施形態では、前記第2の吸引経路において流体管理タンクが流体的に配置され、残留した生検の生体物質の前記サンプルバスケットから前記吸引源への流れを防止している。【選択図】図3
