Abstract
A medical instrument comprising an insertion section, an operation section connected to a proximal end of the insertion section, and sampling means. The insertion section has a sheath comprising an inner tube and an outer tube capable of moving back and forth in an axial direction with respect to the inner tube. The operation section is connected to a proximal end of the inner tube and has suction means for generating a suction force. The sampling means comprises a distal unit provided on a distal portion of the inner tube and having an opening through which a living tissue is to be drawn by the suction force applied from the inner tube, and cutting means for cutting a part of the living tissue drawn into the distal unit as the inner tube and the outer tube are moved relative to each other in an axial direction.
