Abstract

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.
