摘要：
The invention is directed to a system and device for separating and collecting a tissue specimen from a target site within a patient. The device includes a probe component which is releasably secured to the driver component. The probe component has an elongated tubular section, a penetrating distal tip and a tissue receiving aperture in the distal end of the tubular section proximal to the distal tip, and a tissue cutting member which is slidably disposed within the probe member to cut a tissue specimen drawn into the interior of the device through the aperture by applying a vacuum to the inner lumen of the tissue cutting member. The driver has drive members for operating the elements of the probe component. The tissue penetrating distal tip preferably has a triple concave curvature shape with three curved cutting edges leading to a sharp distal point.
