Abstract

Official abstract text for this publication.

Among other things, there are disclosed embodiments of full-core biopsy needles having an outer needle component and a middle cannula through a lumen in the outer component, through which a mandrel may be placed. The outer component includes an internal boss that reduces its internal diameter, and the cannula includes fingers that extend distally. When the needle is inserted for biopsy, tissue enters the outer component and cannula. Moving the cannula forward causes the fingers to engage a surface of the internal boss, resulting in the fingers curving into the tissue. The fingers pinch the tissue while reducing or eliminating compression of the sample to provide an easier removal of the tissue from adjacent tissue, as well as providing a block or backstop keeping the tissue within the needle. Gaps are provided between the fingers to further reduce damage to the tissue sample.
