Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a bronchial occluder with bidirectional bend control. Background Technology

[0002] One-lung ventilation refers to a method in thoracic surgery where the affected and healthy lungs are isolated and ventilated using only one lung via an endotracheal tube. Implementing one-lung ventilation on the healthy side causes lung collapse in the surgical area, creating a clear and stable surgical field, facilitating surgical procedures; it prevents blood and secretions from the affected side from entering the healthy lung, causing unnecessary infection and affecting surgical outcomes; and it helps reduce mechanical damage from partial lung resection. Currently commonly used one-lung ventilation methods include double-lumen endotracheal tubes, bronchial occluders, and endotracheal intubation. Bronchial occluders are a new type of bronchial obstruction catheter that, compared to ordinary double-lumen endotracheal tubes, offers advantages such as simpler insertion and positioning, a larger effective lumen, complete lung isolation, and less physiological disturbance.

[0003] Bronchial occluders are commonly used for single-lung isolation during open-chest surgery. Current bronchial occluders require the assistance of a fiberoptic bronchoscope for placement to achieve single-lung isolation. During surgery, patient movements such as turning or shifting can easily cause displacement of the bronchial occluder's cuff, necessitating adjustment of the cuff position using a fiberoptic bronchoscope. Furthermore, current bronchial occluders offer poor visualization.

[0004] Due to the anatomical features of the human body, the junction of the oral cavity and pharynx is a curved passage. When using an occluder in conjunction with a laryngeal mask airway, it is difficult to insert the tube through the glottis at a fixed angle. Furthermore, the angles between the left and right main bronchuses and the trachea are not exactly the same in different patients (such as children and adults), making the intubation angle need to be individualized.

[0005] Therefore, in clinical applications, there is a need for a bronchodilator that allows for real-time monitoring of the bronchial occluder cuff and adjustment of the tip angle during intubation. This would reduce the difficulty of intubation, minimize airway damage, and help detect bronchial occluder cuff displacement in a timely manner. Utility Model Content
