Plastic hard visible tracheal catheter core

The invention discloses a plastic hard visible tracheal catheter core, which relates to the technical field of medical instruments, and is characterized in that the plastic hard visible tracheal catheter core comprises a catheter body, and a metal guide wire, an optical fiber channel and a conveying channel are arranged on the inner side of the catheter body. In the invention, through the metal guide wire in the tube body, the shape can be kept in the using process, the glottis can be easily reached, the metal guide wire has plasticity, the front section J-shaped angle can be individually adjusted according to different oropharynx structures of patients, and the related problem that the existing device is insufficient in operation flexibility at present is solved; the extension tube is connected with the external oxygen delivery device, the suction device and the injection device, so that oral pharyngeal secretions can be sucked in the intubation process, and the situation that the visual field is affected du
