The present invention provides an inner membrane tube bronchial catheter. The head of the main ventilation tube is equipped with a main ventilation port and a lateral ventilation port, while the tail is provided with two ventilator interfaces. One of the two ventilation ports can be selectively connected to either ventilator interface, thereby forming a membrane ventilation lumen. A front sealing cuff and a rear sealing cuff are respectively arranged at the anterior and posterior sides of the lateral ventilation port, and they are each connected to an inflation tube and an inflation valve. During thoracic surgery, the front sealing cuff is inserted into one bronchial orifice, while the rear sealing cuff remains within the main airway, with the lateral ventilation port oriented toward the opposite bronchial orifice; by inflating or deflating the membranous ventilation tube, lung isolation can be easily achieved, thereby minimizing the catheter's outer diameter, reducing intubation-related injury, and providing a larger ventilation chamber with lower airway resistance when ventilating either lung. Moreover, suctioning and bronchoscopic examination are made more convenient. After the surgery, the front sealing cuff can be deflated and retracted into the main airway, thereby converting the device into a single-lumen endotracheal tube. The catheter has a simple design, is cost-effective, has a low complication rate, and holds significant potential for clinical application.

This utility model provides a cardiothoracic surgical irrigation device, relating to the field of medical device technology, comprising: a main frame assembly; an external fixing component installed on one side of the main frame assembly, and an extension component installed on the main frame assembly near the external fixing component. The external fixing component is directly installed on one side of the main frame assembly, allowing for easy hand-holding and easy locking into position. The extension component, located near the external fixing component, has three sets of external connecting components, facilitating the use of various media. The main frame assembly can control the sprayed media, and its positioning component can fix the opening size, facilitating various desired effects. This solves the problem that existing surgical procedures, due to the different locations of the affected area and the different irrigation media used, cannot achieve the use of any irrigation media, leading to complex surgical procedures and abnormalities.

Patient biomarkers may be monitored before, during, and / or after thoracic surgery to predict complications, detect complications, track recovery, and / or make pre-, in- and / or post-surgery recommendations to avoid predicted complications and / or mitigate detected complications. Complications (e.g., prolonged air leak or esophageal stricture) may be predicted based on patient parameters and / or biomarker measurements. Complications may be predicted or detected based on biomarker measurements compared to thresholds associated with a biomarker (e.g., developed from baselines) generated based on patient parameters, pre- and / or in-surgery biomarker measurements, and / or surgical details (e.g., decrease in long capacity). Recovery milestones may be tracked based on biomarker measurements compared to predicted biomarker measurements for recovery stages. A recommendation (e.g., to avoid a predicted complication and / or mitigate a detected complication) may be a patient-specific selection and / or modification of more of: surgical preparation, in-surgery procedures, surgical instrument selection, surgical and / or post-surgical instrument settings, post-surgery procedures, in-surgery and / or post-surgery monitoring, etc.
