7. The bronchial occlusion device with adjustable visualization angle of claim 6, wherein: the speed reducing motor is a micro stepping motor provided with a gear speed reducing mechanism.
8. The bronchial occlusion device with adjustable visualization angle of claim 1, wherein: the diameter of the plugging catheter is 2 mm-10 mm, and the distance from the front end of the plugging air bag to the tail end of the silica gel head is 10 mm-40 mm; the silica gel head is provided with a plurality of air holes.
9. Use of a visual angularly adjustable bronchial occlusion device according to any of claims 1-8, characterized in that:
(1) and (4) checking: checking the air bag for plugging and monitoring the air tightness of the air bag, connecting a transmission joint with a display device, connecting a power supply joint to a power supply, detecting whether the functions of the camera, the second camera and the steering mechanism are normal or not, and carrying out corresponding adjustment;
(2) placing: the handle is held to enable the plugging catheter to be placed into one side of the lung of the patient through the tracheal catheter placed into the lung of the patient, the camera displays the placement condition through the imaging device, whether secretions exist in the trachea or the tracheal catheter of the patient can also be displayed, and the placement condition of the patient is observed to ensure accurate placement; if secretions exist in the trachea or the tracheal catheter of the patient, the connector of the sputum aspirator is connected with the sputum aspirator, and the secretions in the lung are sucked out through the sputum suction pipeline; the sputum suction pipeline can also be connected with an oxygen machine to supply oxygen to the patient;
(3) turning: when the plugging pipeline enters a bronchus from the trachea, the plugging pipeline needs to be steered, and the step motor is controlled to work by rotating the rotary switch, so that the pinion drives the rotary rod, and the front section of the plugging catheter is pushed to steer; the clockwise rotation and the anticlockwise rotation of the rotary switch respectively correspond to the right rotation and the left rotation, and the rotation amplitude corresponds to the steering angle;
(4) positioning: the plugging catheter is slowly pushed through the picture collected by the camera on the imaging equipment, and the position of the plugging balloon is roughly determined; pulling the adjusting rod, pushing out the second camera through the pushing-out mechanism, observing the position of the plugging balloon and the condition of the bronchus through the developing equipment, releasing the adjusting rod, finely adjusting the position of the plugging catheter to enable the plugging balloon to enter the correct plugging position, and determining the position of the plugging balloon through the second camera again;
(5) and (3) completing plugging: puncturing a rubber plug on the monitoring balloon through an injector, injecting air into the monitoring balloon, and observing the condition of the blocking balloon through a second camera until the blocking requirement is met; and (4) sequentially closing the channels on the side wall of the tail section of the plugging catheter to complete the plugging of the bronchus.
10. The bronchial occlusion device with the adjustable visualization angle as claimed in any one of claims 1 to 8, which discloses an application of the bronchial occlusion device with the adjustable visualization angle in the technical field of medical surgical instruments.
