A bronchoscope is a medical instrument used to examine the airways and lungs. It is a thin, flexible tube equipped with a light and camera, allowing doctors to visualize the inside of the trachea and bronchi. This procedure, known as bronchoscopy, helps diagnose conditions such as infections, tumors, and blockages. During a bronchoscopy, the bronchoscope is inserted through the nose or mouth and guided down the throat into the lungs. It can also be used to collect tissue samples for further analysis. This tool is essential for pulmonologists, specialists in lung health, to provide accurate diagnoses and treatments.
