[0023] The specific implementation of the utility model is described below with reference to the drawings. In order to fully understand the utility model, many details are described below, but the utility model can be implemented without these details for those skilled in the art. For well-known components, methods and processes, the following will not be described in detail.

[0024] Referring to Figure 1 and Figure 2 , a rigid bronchoscope air bag comprises an air bag body 10, the air bag body 10 is clamped on the outer tube wall of a rigid bronchoscope tube body 20, the air bag body 10 comprises a first air bag 11 and a second air bag 12 arranged side by side, the first air bag 11 and the second air bag 12 are both C-shaped structures, and the C-shaped opening of the first air bag 11 is staggered with the C-shaped opening of the second air bag 12 in use. The first air bag 11 and the second air bag 12 are made of latex or thermoplastic polyurethane material, based on the structure design of the air bag body 10 of high elasticity material, the air bag body 10 of the utility model can be well applied to the rigid bronchoscope tube body 20 with an outer diameter of 10-14 mm. When the first air bag 11 and the second air bag 12 are clamped on the rigid bronchoscope tube body 20 with different outer diameters, the opening size of the C-shaped opening of the first air bag 11 and the C-shaped opening of the second air bag 12 also changes correspondingly. The air bag body 10 is connected in communication with the gas outlet end of an inflation pipeline 30.
