摘要：
A vacuum assisted handheld biopsy device having a housing, a stylet slideable within a cannula, the stylet having a hollow tube portion and a tissue collection portion coupled together, an actuator slideable within the housing for driving at least one of the stylet and the cannula, a vacuum source in communication with the stylet, and an ambient air opening in selective communication with the vacuum source. The coupling of the hollow tube portion with the tissue collection portion provides a fluid flow path sufficient to provide a vacuum suction to the tissue collection portion.
