Biopsy assembly for obtaining a tissue sample, comprising - an outer tubular cannula provided with an oblique distal tip, and - a stylet configured to be disposed axially within said cannula and being provided with an oblique distal tip, the stylet having a recess arranged along a side of said stylet, and the recess being configured to receive said tissue sample, - a housing configured to guide and to manipulate said cannula and stylet, and - a rotating member mounted at a proximal end of said stylet or said cannula, wherein the rotating member being configured to rotate said stylet or said cannula around a common longitudinal axis, such that said cannula and said stylet are rotated relative to one another, wherein the rotating member is configured to rotate said stylet and said cannula relative to one another without any substantial relative axial displacement along the common axis between said stylet and said cannula prior to tissue sampling, such that a most distal edge of said oblique distal tip of said cannula is arranged at the same side as said recess when the tissue sampling is performed, and wherein a length, measured along a line parallel to the longitudinal axis of said stylet from a distal end of said recess and to a proximal leading edge of said stylet is between 0 and 2,0 mm, - at least one spring adapted to exert a spring force on said cannula in an axial direction, for moving said cannula axially, wherein the at least one spring is adapted to exert a spring force on said cannula in an axial direction, for rapidly moving said cannula distally to sever said tissue, characterized by a release mechanism, to release said cannula for axial movement relative to said stylet after receiving said tissue sample, the release mechanism comprising at least one retaining protrusion adapted to inhibit distal movement of said cannula until said release mechanism is activated, and wherein a proximal part of the housing is arranged to be axially movable in relation to the distal part of the housing, and the stylet is provided with a proximal elongated extension, forming a moving member, with a proximal handle, the proximal handle arranged in a longitudinal slit of the proximal part of the housing and partially protruding out of one side of the housing. - an outer tubular cannula provided with an oblique distal tip, and - a stylet configured to be disposed axially within said cannula and being provided with an oblique distal tip, the stylet having a recess arranged along a side of said stylet, and the recess being configured to receive said tissue sample, - a housing configured to guide and to manipulate said cannula and stylet, and - a rotating member mounted at a proximal end of said stylet or said cannula, wherein the rotating member being configured to rotate said stylet or said cannula around a common longitudinal axis, such that said cannula and said stylet are rotated relative to one another, wherein the rotating member is configured to rotate said stylet and said cannula relative to one another without any substantial relative axial displacement along the common axis between said stylet and said cannula prior to tissue sampling, such that a most distal edge of said oblique distal tip of said cannula is arranged at the same side as said recess when the tissue sampling is performed, and wherein a length, measured along a line parallel to the longitudinal axis of said stylet from a distal end of said recess and to a proximal leading edge of said stylet is between 0 and 2,0 mm, - at least one spring adapted to exert a spring force on said cannula in an axial direction, for moving said cannula axially, wherein the at least one spring is adapted to exert a spring force on said cannula in an axial direction, for rapidly moving said cannula distally to sever said tissue,
