Resistance Feedback Laryngoscope

A resistance feedback laryngoscope comprising:

• a pushing grip, a trigger pad, a rotary shaft, a first transmitting rod, a second transmitting rod, and a two-step levering blade, the pushing grip including a curved front side, and a bottom end of the curved front side of the pushing grip connecting with the blade set, the two-step levering blade including a first movable blade fixed on a middle section thereof, a second movable blade mounted on a front end thereof, and a fixed blade, the fixed blade coupling with the first transmitting rod and the second transmitting rod, and a front end of the first transmitting rod being coupled with the first movable blade, a front end of the second transmitting rod being connected with the second movable blade, such that the first movable blade and the second movable blade are pushed by the first transmitting rod and the second transmitting rod to raise curvedly;
• the first transmitting rod and the second transmitting rod connecting with the rotary shaft, the rotary shaft being fixed on a drive post, and the drive post having a resilient element fitted therein, the resilient element having a first foot and a second foot, the first foot of the resilient element abutting against a locking peg proximate to the drive post, and the second foot being biased against a side piece of the rotary shaft;
• the trigger pad contacting with two sides of an outer wall of the pushing grip and curving upward slightly, and the trigger pad including an arcuate groove formed therein, a bottom end of the arcuate groove contacting with the side piece of the rotary shaft.
