    摘要: The device for mechanical lithotripsy and removal of stones that form in the bile duct or urinary system has a stone collection basket at a distal end of a tube and two actuators at the proximal end of the tube. A cable runs through the tube and connects each actuator to the basket. The actuators are screw drives and form a common structural unit that is concentric to the tube and the cable. One actuator controls the opening and closing of the basket while the other actuator controls the force transmitted through the cable to the basket to allow for crushing of the stone in the basket.

    摘要: A device (1) for endoscopic removal of stones or concrements from a bile and pancreatic duct or foreign bodies and polyps subsequent to polypectomy in the upper or lower gastrointestinal tract comprises a cable (9) guided in a tube (2) and further comprises, on its proximal end, an actuation element (3) for an axial displacement of the cable (9) within the tube (2). The cable (9) receives, on its distal end, a collecting basket (16) formed by at least four elastic basket wires (17), said basket wires (17) being bundled at one end on the cable (9) and at another end on a guide element (18). The basket wires (17) bear against the end of the tube (2) such that an axial displacement of the cable (9) leads to a loop-like contraction or expansion of the collecting basket (16) and to a twisting of the collecting basket (16) about its longitudinal axis. The tube (2) is configured as a double-lumen tube, the cable (9) being arranged in a first lumen (8) and a guide wire (5) being arranged in a second lumen (19), and a distal end of the guide wire (5) extending axially beyond the tube (2) is not guided relative to the collecting basket (16).
