Abstract:Objective To design a portable ultrathin electronic bronchoscope with a diameter of 1.2~3.6 mm for the examination and
treatment of grade 8-11 bronchus. Methods The portable ultrathin electronic bronchoscope was consisted of a body, a display host
and a large screen component. The body included freely bendable insertion part, camera part, lighting part, etc. The display host
included image processing and control parts, display parts, interface modules, etc. The camera part used miniature low-power image
sensor and ultrathin special shielding wire. The lighting part used miniature high-brightness LED to generate light, and provided
illumination for the camera part through optical fibers. Combined with advanced image processing and control technology, it can
perform medical operation better. Results A non-working channel endoscope with an outer diameter of 1.2 mm and a resolution of
up to 40000 pixels was successfully designed by 0.6 mm edge-length miniature image sensor, And endoscope with an outer diameter
of 2.8 mm and a resolution of up to 160000 pixels was successfully designed by 1.1 mm edge-length miniature image sensor and 1.2
mm working channel. Conclusion The ultrathin electronic bronchoscope achieved the effect of ultrathin and no heat, and adopted
advanced technologies such as portable, storage, wireless and so on, which is more convenient for users to use and teach, and
observation for tracheal intubation.
