Double-lumen bronchial cannula with movable lens

The utility model belongs to the technical field of medical instruments, and particularly relates to a double-lumen bronchial cannula with a movable lens. The device is mainly used in non-cardiothoracic surgeries such as thoracic surgeries, cardiac surgeries and spinal fusion. A main branch pipe and an auxiliary branch pipe are arranged; the lens passage is arranged between the main branch pipe and the auxiliary branch pipe; the lens assembly is electrically connected with external visual equipment, can be placed in the lens passage, and can slide along the extension direction of the lens passage after being stressed; the double-lumen bronchial intubation tube solves the problems that the preparation time before intubation is prolonged and the workload of anesthetists is increased due to the fact that the view field is frequently replaced in the intubation operation process of an existing double-lumen bronchial intubation tube. 本实用新型属于医疗器械技术领域，具体涉及为一种具有可移动镜头的双腔支气管插管；主要用于胸外科手术、心外科手术以及脊柱融合术等非心胸外科手术中；通过设置主支管与副支管
