Zheng Ren kept the guide wire and used it to retract the endoscope. He followed the guide wire into the endoscope again, and inserted a second guide wire into the cystic cavity.
Then, he prepared to use a 10mm cylindrical airbag to expand and puncture the hole.
Zheng Ren was very careful in this step. He did not relax just because he had succeeded many times in the system's operating theater.
He opened the airbag bit by bit, but he did not directly open the puncture holes. Instead, he tested a few spots.
The elasticity and toughness of every part of the body varied in size. Zheng Ren was looking for the most elastic and toughest part of the body.
The flexibility and toughness were similar, and it could even be said that no one other than him could distinguish such a slight pressure during surgery. However, the difference was there.
This was a perfect detail in the surgery, and Zheng Ren tried his best to do it perfectly.
