Abstract

A core biopsy arrangement for taking a tissue sample from a human or animal tissue, preferably from a tumour or a suspected tumour, includes a needle holder member provided with a tissue sampling needle, a longitudinal movement element adapted to apply a longitudinal movement to the needle, wherein the movement of the needle is a reciprocating movement having a stroke length L, wherein the forward movement is faster than the retracting movement, and wherein the reciprocating movement is initiated when the distal end of the needle is subjected to a force in the longitudinal direction.
