The proximal support segment is divided into a front section, a middle section and a rear section that are connected sequentially and coaxially. The front section is of an umbrella shape, and an opening of the umbrella shape faces the middle section. The middle section is of a cylindrical shape, and a diameter of the cylindrical shape is less than a diameter of the opening segment. The rear section is spherical or hemispherical, and a maximum diameter of the rear section is greater than the diameter of the opening segment but not greater than a maximum diameter of the umbrella shape.
