Novel gallstone removing device

The utility model discloses a novel gallstone removing device, which comprises a conical head part, a net basket body, an outer sheath pipe, a connecting component, a Y-shaped valve and a torsion-control guide wire, wherein the conical head part, the net basket body and the torsion-control guide wire are sequentially connected into a whole to form a net basket system; the outer sheath pipe, the connecting component and the Y-shaped valve are sequentially connected into a whole to form a sheath pipe system; and the net basket system is nested in a cavity tract of the sheath pipe system, and can be pushed forwards and backwards and rotate by the torsion-control guide wire. The net basket body adopts a laser-engraved structure, and a far end thereof has a rather high mesh density for fixing the gallstone conveniently and protecting the gallstone from dropping in the withdrawing and hauling process; and a near end of the net basket body has a rather low mesh density for capturing the gallstone conveniently. The net basket body is high in stability and is unlikely to distort in the process of capturing the gallstone, so that the surgical success rate is increased and complications are reduced.
