Biopsy arrangement

A biopsy needle arrangement comprising:

• a needle sheath having proximal end and a distal end, the needle sheath constituting an elongated, along a first direction, hollow tube having a sheath opening at the distal end of the needle sheath;
• the sheath opening being delimited by a first sheath opening edge that defines and is disposed in a first plane and a second sheath opening edge that defines and is disposed in a second plane that is inclined relative to the first plane, the first plane and the second plane intersecting with each other at an angle along a first intersection line;
• and
• a needle having proximal end and a distal end, the needle comprising an elongated, along the first direction, shaft portion configured to fit inside of, and to slide relative to, the needle sheath;
• a tip portion connected to the shaft portion and located at the distal end of the needle;
• and a cavity formed by the shaft portion and extending in the first direction, a second direction perpendicular to the first direction, and a third direction perpendicular to the first and second directions;
• the tip portion having a distal tip and a first proximal tip edge that defines and is disposed in a third plane and a second proximal tip edge that defines and is disposed in a fourth plane that is inclined relative to the third plane, the third plane and the fourth plane intersecting with each other at the angle along a second intersection line;
• wherein:
• the needle arrangement is configured to be in a closed state where the first sheath opening edge abuts the first proximal tip edge and the second sheath opening edge abuts the second proximal tip edge and the first intersection line coincides with the second intersection line.
