The driver 3 is installed on the handle 1, and the driver 3 can be connected to the first driving screw 241 or the second driving screw 261 to drive the first driving screw 241 or the second driving screw 261 to rotate. In this embodiment, the independent driving of the first driving screw 241 and the second driving screw 261 can be realized through the driver 3, and the operation is simple and easy to use.

[0060] Preferably, as Figure 8 shown, the first driving screw 241 and the second driving screw 261 are arranged oppositely. The first driving screw 241 is provided with a first follower gear disk 246, and the second driving screw 261 is provided with a second follower gear disk 266.

[0061] Preferably, as Figure 8As shown, the driver 3 includes a driving runner 31, a first driving gear disc 32 and a second driving gear disc 33. The driving runner 31 is sleeved on the first driving screw 241 and the second driving screw 261, and can slide on the first driving screw 241 and the second driving screw 261, and can also rotate relative to the first driving screw 241 or the second driving screw 261; the first driving gear disc 32 and the second driving gear disc 33 are located on both sides of the driving runner 31. The first driving gear disc 32 faces the first follower gear disc 246 and can be engaged; the second driving gear disc 33 faces the second follower gear disc 266 and can be engaged; when the driving runner 31 is toggled to engage the first driving gear disc 32 with the first follower gear disc 246, the driving runner 31 is fixedly connected to the first driving screw 241 and rotates relative to the second driving screw 261 at the same time. Rotating the driving runner 31 will drive the first driving screw 241 to rotate; when the driving runner 31 is toggled to engage the second driving gear disc 33 with the second follower gear disc 266, the driving runner 31 is fixedly connected to the second driving screw 261 and rotates relative to the first driving screw 241 at the same time. Rotating the driving runner 31 will drive the second driving screw 261 to rotate; by means of a single driving runner 31, the first driving screw 241 and the second driving screw 261 can be respectively driven to rotate, so as to realize flexible switching between adjusting the position of the support wing 22 and the bending angle of the adjustable lens body 25, thereby significantly simplifying the operation process, reducing the operation difficulty and improving the operation efficiency. Especially in an emergency, it can effectively save precious time.

[0062] Embodiment 5

[0063] The improvement of the laryngoscope in Embodiment 4 in Embodiment 5 is as Figure 1 and Figure 3 shown. The laryngoscope further includes a display unit 4. The display unit 4 further includes a display, a camera 41 and a power supply. The power supply is installed in the handle 1 and is used to provide the required power for the camera 41 and the display; the camera 41 is arranged on the end mirror body section of the adjustable lens body 25 and is used to obtain the exact position of the end of the adjustable lens body 25 in real time; the display is rotatably arranged on the handle 1 and is connected to the camera 41. The specific position of the end of the current adjustable lens body 25 can be displayed in real time through the display. When performing medical operations such as tracheal intubation, it can accurately judge whether the end of the adjustable lens body 25 has accurately reached the target position, such as key parts such as the epiglottis and glottis, ensuring that the end of the adjustable lens body 25 can quickly and accurately be positioned at an ideal position and angle and is precisely aligned with the glottis, thereby significantly improving the success rate of tracheal intubation and reducing the time loss and potential harm to the patient caused by repeated adjustments.

[0064] The main mirror body 21 and the adjustable mirror body 23 are also respectively provided with guiding channels for guiding endotracheal intubation, so that the endotracheal intubation can be accurately and quickly inserted into the patient's airway without repeated adjustment, further improving the quality and efficiency of endotracheal intubation operation.

[0065] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention.
