Structural Characteristics
Material: It is usually made of biocompatible materials such as polyvinyl chloride (PVC) and silica gel, which are soft, smooth and durable, reducing irritation and damage to the airway mucosa.
Shape: It is long and slender in shape. According to different designs and uses, its distal end may have different shapes and structures, such as being equipped with an air bag and side holes.
Marking: There are usually clear scale markings on the surface of the catheter, so that medical staff can accurately control the insertion depth.
Functions
Lung Isolation: It can separate the left and right lungs or different lobes of the same lung, preventing pollutants such as secretions, blood and pus in one lung from entering the other lung and preventing cross-infection and the spread of lesions.
Single-lung Ventilation: In some thoracic surgeries, such as lobectomy and esophageal cancer surgery, it is necessary to ventilate one lung while allowing the other lung to collapse to facilitate surgical operation. The endobronchial tube can achieve single-lung ventilation, ensuring a clear surgical field and maintaining the patient's oxygenation and ventilation functions.
Selective Bronchial Blockage: For some localized lung lesions, such as ruptured pulmonary bullae and broncho-pleural fistula, the bronchus of the diseased part can be selectively blocked through the endobronchial tube to achieve the purpose of treatment.
Clinical Applications
Thoracic Surgery: It is one of the commonly used devices in thoracic surgery, which can help doctors to perform surgical operations better, reduce surgical risks and improve the success rate of surgery.
Intensive Care: In the intensive care unit, for some patients with severe pulmonary infection, atelectasis, respiratory failure and other conditions, the endobronchial tube can be used for operations such as bronchoalveolar lavage and secretion suction, which is helpful to improve the patient's respiratory function.
Interventional Therapy: In bronchoscopic interventional therapy, the endobronchial tube can be used as a guiding tool to help the bronchoscope accurately reach the lesion site. It can also be used for ventilation, suction and other operations during the treatment.
