摘要：
Apparatus and methods provided to remove biopsy specimens from bone and/or associated bone marrow. A powered driver may rotate a biopsy needle at an optimum speed to obtain the biopsy specimen. A thread or a groove may be disposed on interior portions of the biopsy needle. The thread or groove may engage a biopsy specimen and enhance removal of a bone marrow core from cancellous bone. Manufacturing procedures are provided for bonding a single helical thread with interior portions of the biopsy needle. The apparatus may also include a biopsy sample ejector and/or ejector funnel. A biopsy needle set may include a cannula and a trocar with respective tips having optimum configurations, dimensions and/or orientations relative to each other to optimize penetration of a bone and/or bone marrow with minimum patient trauma and enhanced reliability of obtaining a biopsy specimen.
