    • The invention is directed to devices and methods for separating and collecting a tissue specimen from a patient's target site. The device includes a probe member with a penetrating distal tip and a tissue receiving aperture, and a tissue cutting member which is rotatable disposed within the probe member to cut a tissue specimen drawn into the interior of the device through the aperture. The longitudinal edges of the aperture are preferably sharpened to engage the cutting edges of the tissue cutting member. Vacuum may be provided in the inner lumen of the cutting member to transport tissue therethrough. Rotation, rotational oscillation and/or longitudinal reciprocation of the tissue cutting member is effective to separate a tissue specimen from surrounding tissue. An accessing cannula having an tissue receiving aperture may be concentrically disposed within the probe member and about the tissue cutting member. The tissue cutting edge of the tissue cutting member preferably is longitudinally oriented and may have a cutting angle less than 90° with respect to the longitudinal axis of the tissue cutting member.
    • 本发明涉及用于从患者的目标部位分离和收集组织标本的装置和方法。 该装置包括具有穿透性远侧末端和组织接收孔的探针构件,以及组织切割构件,该组织切割构件可旋转地设置在探针构件内,以通过孔切割被拉入装置内部的组织样本。 孔的纵向边缘优选地被锐化以接合组织切割构件的切割边缘。 可以在切割构件的内腔中设置真空以将组织输送通过其中。 组织切割构件的旋转,旋转振动和/或纵向往复运动有效地将组织标本与周围组织分开。 具有组织接收孔的进入套管可以同心地设置在探针构件内并且围绕组织切割构件。 组织切割构件的组织切割边缘优选地纵向定向并且可以具有相对于组织切割构件的纵向轴线小于90°的切割角度。
