1. A combined system of a concealed closed tracheoscope and an artificial airway breathing circuit, comprising an artificial airway breathing tubing and a tracheoscope, wherein the artificial airway breathing tubing comprises an inhalation circuit and an exhalation circuit, wherein the inhalation circuit and the exhalation circuit are connected through a connecting tube;
the exhalation circuit comprises: a front-end extendable corrugated tube, a breathing circuit tube provided with a tracheoscope handle portion, and a tail-end extendable corrugated tube, wherein the front-end extendable corrugated tube, the breathing circuit tube and the tail-end extendable corrugated tube are sequentially connected in series; the front-end extendable corrugated tube is connected to the connecting tube; and the front-end extendable corrugated tube is provided with an upward water injection channel and a downward drainage channel;
the tracheoscope comprises the handle portion and an insertion portion connected to the handle portion; a first end of the insertion portion is connected to the handle portion, and a second end of the insertion portion serves as a bent portion; and a head end of the bent portion is provided with a camera lens, a light-emitting diode (LED) light source, and a working channel;
the insertion portion is inserted into the front-end extendable corrugated tube and runs through the connecting tube; and the insertion portion is configured to advance through retraction of the front-end extendable corrugated tube such that the bent portion extends from the connecting tube; and
the handle portion comprises a shell, a tracheoscope bent portion direction control component, and a tracheoscope bent portion direction control handle; the shell has a diameter larger than a diameter of the breathing circuit tube and wraps around the breathing circuit tube; the tracheoscope bent portion direction control component is located inside the shell; and the tracheoscope bent portion direction control handle is connected to the shell through a handle cover, and an operating end of the tracheoscope bent portion direction control handle is exposed.
