    • A handheld biopsy device is provided for the collection of soft tissue samples from a surgical patient. In a preferred embodiment, the biopsy device comprises a handpiece, a fluid collection system, and a power transmission source. The handpiece is configured for grasping by a single hand, and being independently manipulatable by hand for movement of the instrument toward and away from the patient. An elongated piercer extends from the distal end of the handpiece. The piercer has a sharpened distal end for entering the tissue and a port located proximal to the sharpened distal end for receiving a portion of tissue mass. An elongated cutter is disposed coaxially relative to a piercer lumen of the piercer. A distal blade of the cutter slides distally past the port of the piercer to severe the tissue portion drawn into the port by vacuum. The cutter is retracted to a most proximal position for removal of the tissue portion from a cutter lumen of the cutter. The handpiece further comprises a holster for detachably connecting a cutter rotational transmission and a cutter axial transmission to the power transmission source.
    • 提供了一种手术活检装置,用于从手术患者收集软组织样本。 在优选实施例中,活检装置包括手持件,流体收集系统和动力传递源。 手持件构造成用于单手抓握,并且可以用手独立地操作以使仪器朝向和远离患者移动。 细长的穿孔机从手持件的远端延伸。 穿孔器具有用于进入组织的锋利的远端和位于锐化的远端附近的端口,用于接收组织块的一部分。 细长切割器相对于穿孔器的穿孔腔同轴设置。 切割器的远端叶片向远侧滑动穿过穿孔器的端口,以使通过真空吸入端口的组织部分变得严重。 切割器缩回到最近的位置,以从切割器的切割器内腔移除组织部分。 手持件还包括用于将切割器旋转传动和切割器轴向传输可拆卸地连接到动力传递源的机架。
