In recent years, advances in interventional bronchoscopy have led to safer and more effective solutions for the diagnosis and treatment of respiratory diseases. However, the techniques currently used to diagnose and treat peripheral pulmonary lesions (PPL) have certain limitations. Robotic-assisted bronchoscopy (RAB) offers a new solution to these limitations. Currently, three RABs have been approved by the US Food and Drug Administration (FDA) and are successfully marketed, while two domestic RABs are in the research and development stage. This article provided an overview of the advantages and disadvantages of various techniques and introduced five RABs in detail. It also discussed the advantages and disadvantages of RAB technology and future trends in its development.
