Bronchoscope is a set of equipment, including a mirror body and a support. Simply put, it is like a hollow flexible tube with a light source at the front end. After entering the trachea and lungs, observe. If it is necessary to remove the pathology for biopsy, the supporting biopsy forceps are used to extend out of the hollow tube and take out a piece of tissue. You need to do some brushing, and then do something else.
In other words, bronchoscopy must be done for bronchoscopy!
