It was different from normal tumor tissue. What he had seen before was a part of the body. Although it was abnormal hyperplasia and had pathological changes, it was still a part of the body.
However, the watermelon in front of him seemed to have its own independent circulatory system. The stem was like a pipe, constantly squirming … squirming …
The venous blood entered the heart, flowed through the right atrium, entered the right ventricle, and then entered the pulmonary artery to participate in blood oxygen exchange.
After oxygen exchange, the blood flowed from the pulmonary vein into the left atrium, left ventricle, and ascending aorta.
This is the normal route of blood circulation to the heart.
The reason he thought of this was because the big watermelon's pulse was much faster than his heart's.
If it was a living thing, it would be best if it was in the left ventricle. That way, it would receive arterial blood and have more "nutrients".
However, it was in the right atrium, and it was absorbing venous blood.
Could it be an anaerobic organism that didn't like oxygen?
He didn't know if it was because it had been soaked in blood for a long time or if it was originally like this, but the color of the watermelon was dark red.
Zheng Ren gently placed his finger on the big watermelon to determine the time it took for the test subject's heart to beat once. It needed four to five heartbeats.
What a strange thing. He didn't know if the System could perfectly imitate this guy.
Based on past surgeries, blunt dissection would be carried out first to remove it from the right atrium with the least amount of damage. Then, after the surgery was over, they would make an incision to take a look.
Placing the smallest hemostatic forceps between his fingers, Zheng Ren put on the microscope and began to dissociate the peripheral tissues.
The stem of the watermelon was separated, pulled, lifted, and pinched. The wall of the right atrium and the lining of the inferior vena cava were separated and cut off together.
This was the principle of complete tumor resection. There must always be normal tissue around the periphery. Otherwise, as long as there was a trace of tumor cells, recurrence was inevitable.
From Zheng Ren's point of view, this thing was completely tumor tissue. In fact, it was even more malignant than tumor tissue!
The tumor, the right atrial wall attached to the tumor, and part of the lateral wall of the inferior vena cava were completely removed. The inferior vena cava intubation was immediately performed. The operative field was clear after the control band was tightened.
Then, he performed autologous pericardial graft and inferior vena cava repair. He cut two pieces of the pericardium and mended the right atrium and inferior vena cava like a tailor.
Fortunately, the surgical box given by Dr. Charles was fully equipped with all kinds of equipment. They did not even need the smallest needle to solve this problem.
After a series of sutures and no active bleeding, Zheng Ren heaved a sigh of relief.
That was the end of the surgery.
As for suturing, that was the assistant's job. It had nothing to do with him as the surgeon.
The entire surgery was much simpler than that of the tricuspid valve tumor. Zheng Ren successfully completed it in one go.
He didn't care about the test subject's chest. Instead, he went to the side, held the "big watermelon" in his hand, and carefully observed it.
Because there was no blood supply, the two straws moved much more slowly.
Zheng Ren felt that it really had a mind of its own. It was as if the Big Watermelon was communicating with him through a pair of sterile gloves.
Unfortunately, he didn't understand.
That frequency was not Morse code, nor was it any other password system that Zheng Ren knew of.
Let's cut it open and see. Zheng Ren held the 'big watermelon' in his left hand and held the knife in his right hand.
The moment the incision was made, everything in front of him turned bright red. Then, a System notification popped up — surgery failed, surgeon dead.
The System's operating theater disappeared and Zheng Ren stood alone in the System, facing the sneer of the little white fox across the pond.
What the f * ck was going on?
Zheng Ren was dumbfounded.
If the surgery failed, then it was a failure. Why was there suddenly a notification of the surgeon dead?
Time passed quickly. The first thing Zheng Ren did after he recovered was to continue buying surgery training time.
As the System's operating theater rose from the ground, he stepped inside.
This time, the little beast in Zheng Ren's heart roared.
He knew that his guess was right. The space-occupying lesion in Chunu Ansai's right atrium was not a myxoma at all, but an insect egg!
When he cut open the insect egg just now, the insect inside ran out and killed him.
It was really a freaking alien!
The sudden change in attitude made Zheng Ren a little uncomfortable.
The reason why he maintained a respectful and distant attitude toward the supernatural was that Zheng Ren felt that these things could be explained with science.
If it could not be explained, then the technology tree had not reached that level yet.
It was difficult to use one technology tree to explain another technology tree without reaching the pinnacle.
Therefore, Zheng Ren respected it, but he had to stay away.
This was not his world, and it was not his technology tree.
However, when he came to Nanyang, it was inevitable that he would come into contact with these strange things.
Zheng Ren looked at his surroundings and confirmed that he was in the System space, not the outside world.
This time, he did not do extracorporeal circulation and directly began to dissect.
After opening the heart, Zheng Ren carefully pierced a small hole with a lancet and inserted the oval forceps into it.
The test subject was dead.
Zheng Ren used the oval forceps to clamp randomly. In the end, after confirming that it was fine, he dissected the test subject's right atrium.
There was a lot of blood inside. A worm that was like a thin thread was crushed and mixed with the other messy tissues.
This time, Zheng Ren was fine. The System did not indicate that the surgeon had died. It was just that the surgery had failed.
Zheng Ren was sure that it was definitely the problem with this small worm that caused the strange notification of the surgeon's death.
He calmed his mind and performed another surgery. However, this time, he only performed the surgery honestly and did not touch the 'big watermelon'.
The surgery completion rate was 95%.
For an extremely complicated surgery, Zheng Ren had completed it alone. It was already not bad that the System could give such a high evaluation.
When he returned to reality, Zheng Ren heard the sound of a stretcher trolley coming from the corridor.
The quality of the stretcher trolley was not bad. It was better than the ones in Sea City and the 912. The ground was also flat and the sound was very soft.
Although this was called a national hospital, it was a 100% private hospital. All kinds of equipment were prepared for the rich. They did not care about the cost at all.
To be honest, Zheng Ren was a little envious.
"Su Yun, Old He, you guys prepare first. I'll go and explain something to the patient's family," Zheng Ren said.
"Hey, why are you sneaking around again?" Su Yun was obviously dissatisfied with Zheng Ren's actions and nagged.
Zheng Ren looked at Xie Yiren very cautiously and forced out a smile. Fortunately, he was in the operating theater and was wearing a sterile mask, so one could not see how forced his smile was.
Xie Yiren returned a faint smile. Zheng Ren felt that the current world was very warm.
Walking out of the operating theater, Zheng Ren saw Chunu Ansai half-sitting on the stretcher trolley. More than a dozen doctors and nurses around him pushed him over.
"Wait a moment, Mr. Chunu Ansai. I have something to tell you." Zheng Ren stood in front of the stretcher trolley and blocked the way.
