The working steps of the multi-angle wireless visible laryngoscope are as follows:

A) when the laryngoscope is operated, medical personnel hold the laryngoscope through the grab handle 1, the laryngoscope tube 2 is adjusted for different patients, the laryngoscope tube 2 is adjusted by pressing the plurality of pressing blocks 13, the pressing blocks 13 pop out the first through hole at the moment, so that the limiting effect on the adjacent two connecting sections 6 is not realized, the mutual rotation state of the plurality of connecting sections 6 is changed according to the patient condition, the adjustment of the laryngoscope tube 2 is realized, then the plurality of pressing blocks 13 are pressed again, the L-shaped limiting rod 19 enters the spline slotting for limiting again at the moment, the plurality of limiting strips 14 on the pressing blocks 13 simultaneously limit the first clamping strip 15 and the second clamping strip 16, the adjacent connecting sections 6 are fixed, and the shape of the laryngoscope tube 2 is fixed;

B) then according to the required length, the limiting effect of the first limiting bolt 22 can be removed, the fixing seat 21 slides to a proper position on the laryngoscope base 3, then the first limiting bolt 22 is screwed down again to fix the grab handle 1 and the laryngoscope tube 2, the length adjustment is completed, the connecting block 25 is clamped into the connecting groove on the strip-shaped rotating block 8, then the third limiting bolt 26 is screwed in to complete the fixation, so that the fixation of the display screen 7 and the grab handle 1 is completed, then the annular block 23 is rotated to enable the display screen 7 to reach the proper position, then the second limiting bolt 24 is screwed down, the display screen 7 can also be rotated to reach the proper viewing position, and the fixing is performed through the limiting knob 9;

C) the laryngoscope soft shell 5 is heated by the strip-shaped electric heating wires 10, the miniature air pump 29 is enabled to work according to requirements, the miniature air pump 29 inflates the strip-shaped air bags through the air pipe 30, the laryngoscope soft shell 5 is enabled to be in a proper thickness, and then the laryngoscope is used;

D) the laryngoscope tube 2, the grab handle 1 and the display screen 7 can be detached from each other on the laryngoscope, meanwhile, the inside of the grab handle 1 is powered by a battery, the battery can be replaced, and when the laryngoscope tube 2 and the grab handle 1 are detached or fixed, the power-on condition is determined by the connection of the conductive wire 28.

The foregoing is merely exemplary and illustrative of the present invention and various modifications, additions and substitutions may be made by those skilled in the art to the specific embodiments described without departing from the scope of the invention as defined in the following claims.
