| Zusammenfassung: | A soft tissue biopsy device (102, 150, 570, 584, 1302) including:a handle (104, 152, 470, 510, 1604) including a gripping member;an elongated flexible shaft (106, 156, 474) mechanically comprising a hollow distal sampling portion with an internal lumen (624, 1005) and a distal opening (453, 622, 1016) facing a soft tissue;a driving unit (110) configured to rotate the sampling portion with a speed of at least 100 rounds-per-minute (RPM) to 10,000 RPM while the sampling portion axially advances into said soft tissue;wherein said hollow distal sampling portion is configured to apply shearing forces and/or tensile forces on a tissue sample positioned at least partly inside said hollow distal sampling portion during rotation of said elongated flexible shaft;wherein said hollow distal sampling portion comprises a circumferential tapered sharpened cutting edge (455, 626) surrounding said distal opening for cutting said soft tissue. |
