    • A medical device for severing and removing small amounts of internal tissue for biopsy sampling or other purposes is disclosed. Versions of the device may include a hollow probe having a tissue receiving aperture; a cutter having a cutting edge that moves past the tissue receiving aperture, and a cutter driving mechanism. Versions of the device also may include a vacuum plunger within the probe, and coordinated actuation of the vacuum plunger and the cutter driving mechanism whereby an effective vacuum is developed and maintained within the probe to draw tissue into the tissue receiving aperture prior to and during a cutting stroke of the cutter. Versions described may be used for removing multiple samples of tissue during a single insertion of the probe proximate to a target tissue mass.
    • 公开了用于切断和去除少量内部组织用于活组织检查取样或其它目的的医疗装置。 装置的版本可以包括具有组织接收孔的中空探针; 具有移动经过组织接收孔的切割边缘的切割器和切割器驱动机构。 装置的版本还可以包括探针内的真空柱塞,以及真空柱塞和切割器驱动机构的协调致动,由此有效真空被发展并保持在探针内,以在组织接收孔之前和期间将组织拉入组织接收孔 切割行程。 所描述的版本可以在探针接近目标组织块的单次插入期间用于去除多个组织样品。
