| description | The embodiment of the invention provides a laryngoscope and a video laryngeal mask, the laryngoscope comprises a video tube and a hard lantern ring arranged on the video tube, and the video tube is used for being matched with a video channel of the laryngeal mask in a pluggable mode; and a friction part, in contact with the inner wall of the video channel, of the hard lantern ring protrudes out of the circumferential outer surface of the video tube. According to the laryngoscope, in the process that the video tube is inserted into the video channel, the hard lantern ring makes friction contact with the inner wall of the video channel, on one hand, the friction coefficient between the hard lantern ring and the inner wall of the video channel is relatively small, on the other hand, the contact area between the video tube and the inner wall of the video channel can be reduced, and therefore the contact area between the video tube and the inner wall of the video channel is reduced.
