The front end if the needle is provided with a tissue receiving means cooperatingwith the cutting edge of cannula; an inner needle having located inside and coaxially withthe hollow biopsy needle; a vacuum unit coupled to the hollow biopsy needle; thecannula and hollow biopsy needle being mutually axially moveable. The vacuum unit isadapted to create a lowered air pressure in the inner cavity when the front end of thehollow biopsy needle is axially moved away from the front end of the inner needle. Thevacuum unit is located uniaxially with the cannula and hollow biopsy needle.
