An integrated portable design combines an HD camera, miniature light source, and working channel. The soft, flexible insertion tube enters the trachea and bronchi and transmits HD images to an external display in real time, helping clinicians observe airway structures, diagnose lesions, and perform sampling or treatment. Its ready-to-use single-use design avoids the cross-infection risk caused by incomplete disinfection of conventional reusable bronchoscopes and removes the associated disinfection and maintenance costs.
