Abstract:
1. A biopsy device, comprising: a stylet having a sample recess at a distal end, and a cannula having a sample acquisition port and a sample recovery port; the stylet configured to move within the cannula to move its sample recess from the sample acquisition port to the sample recovery port; a cover member, movable relative to the stylet, to cover the sample recess selectively; and a transport mechanism connected to move the stylet and the cover member, the transport mechanism configured to move the cover member to cover the sample recess when a sample is received therein such that a sample in the sample recess is prevented from rubbing against the cannula when the stylet having the sample recess is moved relative to the cannula, the transport mechanism configured to move the cover member to uncover the sample recess to recover the sample when the sample in the sample recess of the stylet is moved to the sample recovery port of the cannula.
