1. A device (1) for collecting samples of biological tissue, comprising a needle (3) and a cannula (4), positioned at a distal end (5) of the device (1) and coaxially arranged along an axis (A) and slidable with respect to each other along the axis (A); a covering sheath (6), surrounding the needle (3) and the cannula (4); and an actuating mechanism (7), positioned at a proximal end (8) of the device (1) and connected to the needle (3) and the cannula (4) for moving the needle (3) and the cannula (4) in the sheath (6); wherein the actuating mechanism (7) is connected to the needle (3) and the cannula (4) by respective flexible operation cables (10a, 10b), capable of transmitting axial forces in both directions;
wherein the needle (3) has a stem (11) provided with a front tip (12) and a rear end element (13), positioned at respective axially opposite ends of the stem (11) and radially protruding from the stem (11) and extending radially about the stem (11) to define a collecting seat (14) shaped to receive a sample of tissue, and the position of the end element (13) on the stem (11) is adjustable axially to change the distance of the end element (13) from the tip (12) and thus the axial length of the seat (14).
