BENDABLE URETER GUIDE SHEATH

The present utility model relates to the technical field of medical apparatuses, and in particular to a bendable ureter guide sheath, comprising a sheath tube. The sheath tube is of a bendable tubular structure composed of a main body section and a tail section, one end of the tail section is connected to a tail end of the main body section, the elastic modulus of the tail section is lower than that of the main body section, and after a flexible ureteroscope passes through the tail section, the tail section can bend along with the flexible ureteroscope. By means of the present utility model, the tail section of the ureter guide sheath can be synchronously bent along with the flexible ureteroscope, a sheath opening of the ureter guide sheath can reach a position close to stones along with the flexible ureteroscope, fine stone powder can be rapidly discharged from the body along the ureter guide sheath when the stones are crushed, larger stones can be completely removed during an operation in combination with t
