Its characteristics are: it consists of Anderson localizing optical fiber with annular waveguide, illumination light source, surgical light source, optical fiber wavelength division multiplexer, optical fiber side polished coupler, and camera system. In the composition: (1) The illumination light beam transmitted in the annular waveguide provides intravascular illumination. The Anderson localizing optical waveguide channel of the Anderson localizing optical fiber with the annular waveguide collects and transmits the intravascular image information to the camera system for detection to find the lesion region； (2) The surgical light beam transmitted in the annular waveguide removes the lesion region in the blood vessel.1/3 DRAWINGS 1-1 1-2 FIG.1 2 1 FIG.2
