Example (b):

as shown in figure 1, the airway anastomosis protector comprises a catheter 1 and is combined with figure 3, two cuffs are arranged at the end parts, extending into an airway 7, of the catheter 1, the two cuffs are a first cuff 2 and a second cuff 3 respectively, when the airway anastomosis protector is used, the first cuff 2 is placed in a bronchus of a stump on the operation side of a patient, and the second cuff 3 is placed in the bronchus of a donor lung.

In use, there are two ways to inflate the cuff, a common inflation tube in figure 1 and separate inflation tubes in figure 2.

As shown in figure 1, the first cuff 2 and the second cuff 3 share one inflation tube I6 and one inflation valve, the inflation tube I6 inflates the two cuffs simultaneously to seal two sides of the suture area, of course, the inflation tube I6 can inflate the cuffs with liquid and the like to swell the two cuffs, and meanwhile, the inflation valve is replaced by a liquid control valve when the liquid is inflated.

As shown in figure 1, the first cuff 2 and the second cuff 3 are communicated through an access tube 9, and the access tube 9 is embedded in the side wall of the catheter 1 for convenient arrangement and use.

As shown in fig. 2, the first cuff 2 and the second cuff 3 are respectively matched with an inflation tube, which is a second inflation tube 10 and a third inflation tube 11, and are respectively provided with an inflation valve, the second inflation tube 10 inflates the first cuff 2 or fills liquid, and the third inflation tube 11 inflates the second cuff 3 or fills liquid.

In use, the distance x between the first sleeve 2 and the second sleeve 3 is 1-5cm, in this example x is 3 cm. A certain space is left between the two cuffs, which is convenient for the suture of the operation.
