Chương 2590: It ended before it even started.

As the airtight lead door closed, the surgery officially began.

Zheng Ren used a 7.5mm tracheostomy tube to explore the bronchi. He then used a 6 Fr JR 4 guidance tube to enter the bronchi, and a 0.035-inch guide wire followed the bronchi tube in.

There was no problem with these steps. Although boss Zheng was more skilled, Zhou chunyong could also do it. Although his movements were much slower than boss Zheng 's, it was not fatal even if he was a dozen or so seconds late.

After that, the guidance catheter extended out from the side hole of the bronchic catheter to reach the foreign object, and Zheng Ren sent in the micro capture device that he had just selected.

Zhou chunyong started to hold his breath. The next step was the most crucial one! He had performed the operation 16 times before. Once, he successfully used a 3-Fr vascular clamp to remove the foreign object and sent it to the level of the vocal cord.
