The primary bronchus utilized during therapeutic or surgical bronchoscopies is the rigid bronchus. This type of bronchoscopy uses a sturdy and straight metal tube, which allows for better access to the airways and visualization of larger structures. The rigidity of the instrument makes it suitable for procedures that may require significant manipulation or the removal of large airway obstructions, such as foreign bodies or tumors.

Rigid bronchoscopes are often preferred in therapeutic settings because they can accommodate larger instruments, such as forceps and suction devices, which may be necessary for certain interventions. Their design provides a clearer field of view and is often used in conjunction with other surgical tools, enabling a more effective approach to treat specific pulmonary conditions.

In contrast, flexible bronchoscopes are typically employed for diagnostic purposes and for less invasive procedures. They are useful for examining the airways and collecting tissue samples but may not provide the same level of control or access during more complex therapeutic interventions. Fiberoptic and video-assisted bronchoscopes also have their respective uses, leaning more towards diagnostic imaging and visualization rather than surgical intervention.
