    • The invention is directed to tissue cutting members and biopsy devices with such tissue cutting member for separating a tissue specimen from a patient's body at a target site. The tissue cutting member is slidably disposed within an inner lumen of an elongated probe member of the biopsy device to cut a tissue specimen drawn into the interior of an outer cannula of the biopsy device through a tissue receiving aperture in the probe. The tissue cutting member has a tubular distal portion with a distal tip having an outer tissue cutting edge, an inner tissue receiving aperture, and a longitudinally oriented opening with a closed proximal end and open distal end which opens to the inner tissue receiving aperture to facilitate flaring of the distal tubular portion. The cutting member has at least one opening in a wall of the tubular portion to maintain a vacuum during use.
    • 本发明涉及具有这种组织切割构件的组织切割构件和活检装置,用于在目标部位处将组织标本与患者的身体分离。 组织切割构件可滑动地设置在活检装置的细长探针构件的内腔中,以通过探针中的组织接收孔切割拉入活检装置的外套管内部的组织样本。 组织切割构件具有管状远端部分,远侧末端具有外部组织切割边缘,内部组织接收孔和纵向定向的开口,其具有封闭的近端和敞开的远端,其通向内部组织接收孔以便于 远端管状部分的扩口。 切割构件在管状部分的壁中具有至少一个开口,以在使用期间保持真空。
