[0051] Optionally, the image sensor 53 is a CCD or a CMOS.

[0052] Working principle of the image acquisition module: After the handle member 1 is installed in place, the image acquisition module is turned on. The light emitted by the light source is transmitted to the inner side of the sleeve through the first optical fiber 7 and is exported through the light guide ring 59. After illuminating the object to be measured, the image sensor 53 acquires the image inside the patient's trachea.

[0053] Illumination principle: The light emitted by the light source is transmitted to the inner side of the sleeve through the first optical fiber 7. The cladding 72 of the first optical fiber 7 disposed in the spiral groove 573 scatters the light to the inner side of the sleeve. The scattered light is reflected multiple times through the outer wall of the lens barrel 51, the outer wall of the first reflector 55, the inner wall of the second reflector 56, the outer wall of the guide cylinder 57, and the inner wall of the sleeve 58 to homogenize the outgoing light, making the outgoing light more uniform.

[0054] The image acquisition module integrates image acquisition, ranging, and illumination, reducing the volume of the device while improving the functions of the system. The use of two optical fibers, namely the first optical fiber and the second optical fiber, realizes illumination and ranging, which has a significant improvement compared with the large-volume ranging module and the optical fiber bundle used in the prior art.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention.
