    摘要： The set of biopsy needles of the invention is provided with a shaft member for an inner needle 6 which has an inner needle base 22 at the front end to fix an inner needle 24, a shaft member for an outer needle 13 which has an outer needle base 21 at the front end to fix an outer needle 23, a gripping member 1 for operation which fixes the shaft member for the inner needle 6 and axially movably support the shaft for the outer needle 13, a actuating member 9 which gives protrusion force to the shaft member for the outer needle 13, a holding member 15 which holds the shaft member for the outer needle 13 at the position before protrusion against the protrusion force of the actuating member 9 and releases from holding the shaft member for the outer needle 13 before protrusion by outside operation, and a rotation generating member 10 which gives rotation force to the shaft member for the outer needle 13 when the shaft member for the outer needle 13 moves axially.

    摘要翻译： 本发明的活检针组具有用于内针6的轴构件，内轴6在前端具有内针座22，用于固定内针24，外针13的轴构件，其具有外针 基部21在前端固定外针23，用于操作的夹持构件1，其固定用于内针6的轴构件并且轴向可移动地支撑外针13的轴;致动构件9，其将突出力提供给 用于外针13的轴构件，保持构件15，其在突出之前的位置处抵靠驱动构件9的突出力保持外针13​​的轴构件，并且在保持外针13​​的轴构件之前释放 以及当外针13的轴构件轴向移动时向外针13的轴构件施加旋转力的旋转产生构件10。
