Description

Technical Field

[0001] The utility model relates to the technical field of tracheal occlusion catheters, and particularly relates to a occlusion device for assisting in segmental surgery. Background Art

[0002] At present, the main process of thoracoscopic surgery is to perform unilateral lung ventilation by using an occlusion balloon or a double-lumen tracheal intubation. The lung on the surgical side undergoes total lung collapse. The surgeon anatomically locates the lung segment or sub-lung segment to be resected based on experience and then performs the resection surgery. For junior doctors or in cases where the lungs themselves have complications such as emphysema, pleural adhesion, pulmonary fibrosis, etc., it is often impossible to quickly and accurately locate the lung segment or sub-lung segment. Usually, an electronic bronchoscope is used to guide a double-balloon occluder to enter through the airway. The distal balloon is placed at the opening of the lung segment or sub-lung segment bronchus to be resected, and the proximal balloon is placed in the main bronchus for simultaneous occlusion, enabling the collapse of the affected lung while keeping the lung segment or sub-lung segment to be resected inflated.

[0003] The length of the sub-lung segment occlusion tube of the existing double-lumen tracheal intubation is fixed and cannot be adjusted in length according to the bronchial conditions of the patient. There will be a situation where the length of the sub-lung segment occlusion tube is too long and the position where the balloon needs to be inserted is too close, resulting in the bending of the segment occlusion tube. This situation will hinder the doctor's operation when pushing medical devices through the sub-lung segment occlusion tube. Summary of the Utility Model
