"Oh, boss, have you done this?" Su Yun glanced at Shu Ye and said in surprise.

"Yes." Zheng Ren said in a deep voice.

"What do you want to do so quickly? "

"I'm worried about abnormal situations and the temperature is super low, so I feel more at ease. I'm in the operation, and I'm doing it relatively quickly." Zheng Ren said lightly while undergoing the operation.

In fact, Zheng Ren was too busy to be busy in the system operating room.

So you have to get used to the ultra-low temperature.

I had known that assistants, instrument nurses, and anesthesiologists could cooperate so well, and they needed ultra-low temperatures of yarn.

After only a while of chatting, Lin Ge told a gossip. Zheng Ren had already freed from the endometrium of the blood vessels and reached the position of the pulmonary valve.

The endometrium was incised and the pulmonary valve was removed directly.

This is not a simple pulmonary valve stenosis surgery or a valve replacement surgery. It is enough to remove the pulmonary valve and then replace the prosthetic valve or autologous valve.

The valve was removed and the tumor tissue attached to the endometrium of the blood vessel was cut down along the valve.

With the naked eye, he was moving very slowly and could hardly feel his hands moving.

Su Yun stopped talking, watched Zheng Ren's operation quietly, and began to help open the pulmonary artery and assist in removing the tumor tissue.

Although I did this very quickly, it only took nearly 30 minutes to retrieve the tumor tissue.

Finally, the tumor tissue was cut down with hemostatic forceps.

Throw it into the pathological basin, and the hemostatic forceps hit the edge of the metal basin, making a crisp sound.

The main process of the operation has been completed, and the rest is to replace the prosthetic valve.

Zhao Yunlong turned his head and said to the tour nurse: "Help me wipe my sweat."

"Old Zhao, you didn't do anything either. Why did you sweat so much?"

Zhao Yunlong didn't say anything and continued to undergo the operation with a serious look on his face.

"Old Zhao, you're not good at this. You don't want to speak during the operation." Su Yun helped Zheng Ren and said contemptuously: "If you do it in the future, I'll ask Fang Lin to come up. It's better than finding a wooden platform like you."

"Fang Lin can't do it." Zhao Yunlong focused on his hand for Zheng Ren and said, "Can anyone come up and do it?"

"Boss, is this surgery not difficult?" Su Yun asked.

"It's okay." Zheng Ren began to remove the calcification foci.

Three leaves of the pulmonary artery valve were left with 2mm on the edge. Zheng Ren removed the valve, then cleared the calcified tissue on the valve annulus, and used a valve detector to measure the valve annulus to determine the number of the artificial valve.

Zhao Yunlong came up with various valves. Zheng Ren chose the same one. The nurse on the tour opened it and Xie Yiren handed it over.

"Line." Zheng Ren stretched out his hand.

Xie Yiren then patted Zheng Ren's hand with a 2-0 nylon suture stitch with double-headed needles that had just been opened and was wearing a 2-0 nylon suture with a double-headed needle.

The mattress-style suture is interrupted from top to bottom, and then the veil ring is immediately sewn on the suture ring of the artificial heart valve. Zheng Ren is careful.

The sutures should be evenly distributed and proportionate on the suture rings of the annulus and artificial heart valves, with a needle spacing of 2mm.

"Boss, your hand is too stable, it's good." Su Yun said.

"fine."

"Next time, I'll just let Lao Zhao give you a table. This surgery is too depressing." Su Yun said this, but his hands didn't stop at all, helping Zheng Ren thread and press the valve.

The 2mm needle spacing is like measuring with a ruler.

"Boss Zheng, your level is really high." Lao He looked at it and said with emotion.

"What's wrong, Lao He? I mean I didn't do well in the surgery." Su Yun looked at Lao He with contempt.

"Doctor Su, the time you saved Mr. Zhao three years ago was not anesthesia, but I saw your surgery." Lao He said seriously, "I saw it at that time, and it was shocking."

Su Yun was not proud, and there was obviously something to say later.

"But the affinity of the needle spacing, Dr. Su seems to have not reached this level, as if he was measured with a ruler." Old He said.

"Isn't it necessary?" Su Yun said contemptly: "As long as it can be sewn and not bleeding, what should I do if I do something about Humi? Do you think I can't do it?"

"Hehe." Old He smiled dryly, obviously his thoughts were different.

"Prepare to implant." Zheng Ren suddenly interrupted the two of them.

"I can't stand this kind of thing when I have valve surgery, it's like I'm going to get pregnant." Su Yun muttered.

The implantation at this time is different from the implantation of a fertilized egg.

Zheng Ren was obviously in a state of being left alone and didn't hear what Su Yun was saying.

He straightened all the sutures, pushed the artificial flap under the annulus, and confirmed that the implantation was in place.

After repeatedly confirming that the prosthetic valve did not block the left and right coronary arteries, Zheng Ren was relieved.

Three people, one by one, tie a thread, one by one.

Zheng Ren checked again last and confirmed that the opening of the left and right coronary arteries was unobstructed and that coronary stenosis was not caused by the problem of the line knot.

Be careful here, otherwise the patient will immediately develop symptoms of myocardial infarction after the operation is completed.

"Rinse." Zheng Ren said.

The basin of ice salt water was handed over.

Zheng Ren thoroughly rinsed the aorta and left ventricle above and below the prosthetic valve, and filled the aorta and left ventricle with normal saline.

“Sewing.”

The needle holder with 5-0 sutures was slapped in Zheng Ren's hand.

Suspend two pulmonary artery incisions continuously, tighten the last needle to exhaust.

If gas is left here, it is an iatrogenic air embolism.

In the operation, no details can be missed. Otherwise, just such a small detail will lead to the death of the patient.

After the right heart and pulmonary artery are exhausted, the pulmonary artery blocking forceps are opened.

Keep the right heart drainage smoothly and avoid right heart swelling. Because it is ultra-low temperature, the possibility of the heart beating on its own is not high. Zheng Ren directly uses electric shock to tremble and resuscitate.

The heartbeat resuscitated and everyone breathed a sigh of relief when they saw their heart beat well.

After resuscitation, the heart is beating free of load for a period of time without any problems.

Zheng Ren opened the upper and lower vena cava blockade belts and entered the parallel circulation. After the auxiliary circulation for a period of time, the shutdown conditions were met, and Lao He stopped the machine in time.

"You guys come on." Zheng Ren turned around and stepped down.

"Boss, your typhoon is getting worse and worse." Su Yun nagged.

"Aren't I in a hurry to see the pulmonary valve tumor?" Zheng Ren came out of the state of concentration at this time, smiled and said, "Have you seen the pulmonary valve tumor?"

"No." Su Yun and Zhao Yunlong began to find the bleeding spots, suture the pericardium, leave drainage strips, and close their chests.

The operation was successful. After the patient's heartbeat resuscitation, the blood oxygen saturation reached 100% directly while absorbing pure oxygen.

It's okay, Lao He made a judgment directly.

He leaned over to Zheng Ren and asked with a smile: "Boss Zheng, I thought you would have to have ultra-low temperatures and the operation would take at least 4 hours."

"It's not that you can cooperate well. The extracorporeal circulation is smooth and unexpectedly smooth." Zheng Ren held the lancet in his hand and dissected the tumor tissue in the pathological pelvis.
