Background

Airway stenosis is a complication of a number of benign and malignant lung diseases, such as post-tracheal intubation or dissection, tracheal or bronchial nodules, tumors. Patients often develop chest distress, asthma, dyspnea, and recurrent pulmonary infections due to airway narrowing. Bronchoscopic balloon dilation is a common and effective method for treating airway stenosis at present, and has the advantages of small wound and safety. Depending on the degree of stenosis, the balloon with the larger diameter needs to be replaced step by step to achieve the desired dilation effect. When the same patient is subjected to airway expansion, different types of balloons are generally required to be replaced, so that the time required by clinical operation is increased, and the treatment cost of the patient is increased. Therefore, the balloon capable of meeting different expansion diameters is designed, so that the clinical operation is facilitated, and the treatment cost of a patient is reduced.
