摘　　要：目的:研制一种用于单肺通气的可移动气管套管导管,以弥补目前使用双腔支气管导管、支气管封堵器进行单肺通气存在的不足。方法:在短气管导管中内置一根长气管导管,组成一根完整的气管套管导管,内置导管在外套管内能够旋转和移动,完成气管插管后,根据手术需要通过旋转选择内置导管前端方向,将内置导管向前推移插入左或右支气管进行单肺通气,结束手术后,将内置导管从支气管退出到气管进行双肺通气或从外套管中拔出由外套管进行双肺通气。结果:①可移动气管套管导管通过将内置导管插入左或右支气管,单肺通气效果确切;②插管技术比双腔支气管导管和支气管封堵器简单;③内置导管在外套管内旋转移保护患者气道不受损伤,避免使用双腔管术后更换气管导管过程以及换管困难造成患者缺氧和将气管导管误插入食道造成食道手术吻合口损伤的风险。结论:可移动气管套管导管设计合理,插管操作简单,临床实用性强,产品转化可行性大。Objective:To develop a catheter of movable tracheal cannula for single lungventilation so as to compensate the existed disadvantages of using double-lumen bronchialcatheter and bronchial occlusive device in single lung ventilation in present.Methods:Along tracheal catheter was installed into a short endotracheal catheter so as to form a complete catheter of trachealcannula.The internally installed catheter could be rotated and moved in the cannula.After then,the front-enddirection of internally installed catheter was chose through rotated the catheter according to the requirement ofoperation,and the single lung ventilation could be achieved when the internally installed catheter was pushedforward and was inserted in left or right bronchus.After the operation,the internally installed catheter exitedout from bronchus to trachea and was used to implement double lung ventilation,or it was pulled out from outercannula and the double lung ventilation was implemented by using outer cannual.Results:The ventilation effectof single-lung was doubtless when the catheter of movable tracheal cannula was inserted in left or right bronchusby using internally installed catheter.The technique of intubation tube was simpler than that of double-lumenbronchial catheter and bronchial occlusive device.The internally installed catheter could rotate in the outer cannulaso as to protect tracheal wall and avoid oxygen deficit of patient during the processes of replacing tracheal catheterand the difficulty of replacing tracheal catheter post-operation of double-lumen bronchial catheter.Besides,it alsocould avoid the injury risk of anastomotic stoma of esophageal surgery caused by mis-insertion of tracheal catheterin esophagus.Conclusion:This kind of removable tracheal cannula has reasonable design,simple operation ofintubation and better clinical practicability,andits feasibility is better that the product is transformed.
