<p>An adjustable bent sheath tube (100) and delivery system having same, the adjustable bent sheath tube (100) comprising a tube body (101); the tube body (101) has a distal end and a proximal end; reinforcing ribs (105) and traction fibers (104) are axially provided in the tube wall of the tube body (101); the distal ends of the traction fibers (104) are fixed on the distal end of the tube body (101); the proximal ends of the traction fibers (104) extend out of the tube body (101) to connect to an operating handle; the delivery system comprises the adjustable bent sheath tube (100), a sheath core (200) disposed inside the adjustable bent sheath tube (100), and the operating handle fixed with the proximal ends of the adjustable bent sheath tube (100) and the sheath core (200); and the proximal ends of the traction fibers (104) are fixed on the operating handle. The adjustable bent sheath tube (100) facilitates the adjustment of the distal end direction of the adjustable bent sheath tube (100), improves the controllability of the distal end bent direction of the adjustable bent sheath tube (100), and easily controls the movement of the distal end of the adjustable bent sheath tube (100) toward a lesion site.</p> |
