Because the maxillary sinus forceps need to extend into the affected part of the maxillary sinus of a human body and are deep, the forceps body is generally in a slender rod shape. In order to avoid the problems that the volume of the maxillary sinus forceps is excessively increased, the view field is excessively shielded and the operation space is occupied due to the fact that the volume of the maxillary sinus forceps is excessively increased, and the optical fiber and/or the pipeline for illumination are/is arranged on the outer side of the forceps body in an externally hanging mode. The structure can also realize the effects of quick overhaul and maintenance, and reduce the difficulty of repair and maintenance.
