The present invention relates to a biopsy device (1) for obtaining a tissue sample. The biopsy device comprises an elongated tube shaped drill (2), extending along a longitudinal axis A, and comprising a cutting edge arrangement (3) at a distal end (4) of said drill (2). The drill (2) further comprises at least one flute (5) extending helically, along said longitudinal axis A, at an outer surface (6) of said drill (2), wherein said flute (5) extends from said distal end (4) and along a substantial part (7) of said outer surface (6) of said drill(2). The drill (2) is provided with an opening (10) at its distal end (4), wherein said opening (10) being in communication with a cavity (16) adapted to receive said tissue sample. The cutting edge arrangement (3) comprises a first cutting edge (11), adapted to perform a cutting action when said drill (2) is rotated in a first direction(d), and said first cutting edge (11) comprises at least one longitudinal cutting edge (13) extending essentially along said longitudinal axis A.La présente invention concerne un dispositif de biopsie (1) permettant dobtenir un échantillon de tissus. Le dispositif de biopsie selon linvention comprend un foret (2) en forme de tube allongé, qui sétend le long dun axe longitudinal A, et comprenant un agencement à bord tranchant (3) au niveau dune extrémité distale (4) dudit foret (2). Le foret (2) comprend en outre au moins une cannelure (5) sétendant de manière hélicoïdale, le long dudit axe longitudinal A, au niveau dune surface extérieure (6) dudit foret (2), ladite cannelure (5) sétendant à partir de ladite extrémité distale (4) et le long dune partie substantielle (7) de ladite surface extérieure (6) dudit foret (2). Le foret (2) est pourvu dune ouverture (10) au niveau de son extrémité distale (4), ladite ouverture (10) se trouvant en communication avec une cavité (16) adaptée à recevoir ledit échantillon de tissus.
