Unlike normal tumor tissues, what you saw before were all part of the body. Although it was abnormal hyperplasia and pathological changes, it was still part of the body.

But the big watermelon in front of me seems to have its own independent circulation system, and the stems are pipes, constantly squirming... squirming...

Venous blood enters the heart, flows through the right atrium, into the right ventricle, and then into the pulmonary artery to participate in blood oxygen exchange.

The blood after blood oxygen exchange enters the left atrium from the pulmonary vein, the left ventricle, and the ascending aorta.

This is a normal way of blood circulation in the heart.

The reason why Zheng Ren thought of this was because the pulsation of the big watermelon was inconsistent with the heart beat, and it was much faster.

If it is a living creature, it is best to be in the left ventricle, so that the arterial blood is received and the "nutrition" is more abundant.

But it is in the right atrium and absorbs venous blood.

Could it be that this is an anaerobic organism that doesn't like oxygen?

I don’t know if it’s because of long-term blood soaking, or if it’s like this, the big watermelon is dark red and it’s so sluggish.

Zheng Ren gently put his finger on the big watermelon to determine the time for the test body's heart to beat once, and it must beat 4-5 times.

What a weird thing, I don’t know if the big pig’s hooves can perfectly simulate this guy.

According to the past habit of performing surgery, it is definitely necessary to first separate bluntly, remove it from the right atrium with the minimum damage, and then wait until the operation is over before incision.

The smallest hemostasis forceps were placed in the fingers, and Zheng Ren put on a microscope to start floating the tissues on the edge.

The entire pedicle of the watermelon was separated by Zheng Ren. The right atrium wall and the lateral wall endometrium of the inferior vena cava were separated and cut off together.

This is the principle of complete tumor removal, and normal tissue must always be carried around the periphery. Otherwise, as long as there is a trace of tumor cells, recurrence will be inevitable.

In Zheng Ren's opinion, this thing is completely tumor tissue, and it is even more "malignant" than tumor tissue!

The tumor body and the right atrial wall attached to the tumor body and part of the inferior vena cava were completely removed, and the inferior vena cava cannula was immediately replaced, and the post-control belt was tightened and the surgical field was clear.

Then Zheng Ren used autologous pericardial tablets and inferior vena cava to repair the right atrium and inferior vena cava. He cut two pericardial tablets and cut them into the right atrium and inferior vena cava like a tailor.

It is simply that the surgical box provided by Dr. Charles is complete with all kinds of equipment, and it is not necessary to use the smallest needle to solve this problem.

After continuous sutures and no active bleeding was found, Zheng Ren breathed a long sigh.

The operation ended here.

As for stitching, it is the assistant's job and has nothing to do with me as a craftsman.

The whole operation was much simpler than a tricuspid valve tumor, and Zheng Ren completed it successfully in one go.

He didn't care about the matter of testing the chest, but came aside, held the "big watermelon" in his hand, and observed it carefully.

Because there was no blood supply, the two straws were significantly slower to peristalsis.

Zheng Ren felt that it was really sensible, as if the "big watermelon" was communicating with him through sterile gloves.

Unfortunately, I don't understand.

That frequency is not Moss code, nor is it any other password system that Zheng Ren knows.

Cut it open and take a look. Zheng Ren held the "big watermelon" in his left hand and held a knife in his right hand, cutting it with one knife.

At the moment of incision, everything in front of Zheng Ren turned bright red, and then the system prompted that the operation failed and the surgeon died.

The system operating room disappeared, and Zheng Ren stood alone in the system space, facing the ridicule of the little white fox on the other side of the pond alone.

What's going on?

Zheng Ren was stunned.

If the operation fails, it fails. Why is there a sudden hint of the surgeon's death?

Time passed quickly, and the first thing Zheng Ren did after he recovered was to continue purchasing surgical training time.

As the system operating room rose from the ground, he stepped directly into it.

This time, the little wild beast in Zheng Ren's heart roared.

He knew that his guess was correct. The placeholder lesions in Chunu'ansai's right atrium were not myxomas at all, but insect eggs!

I just cut the eggs myself, and the insect body inside ran out to kill myself.

What a fucking alien!

The sudden change in painting style made Zheng Ren feel a little uncomfortable.

The reason why he maintained a respectful and distant attitude towards some of the things that were strange and powerful was because Zheng Ren felt that all of these could be explained by science.

If it cannot be explained, it means that the technology tree has not reached that level.

It is difficult to use one technology tree to explain another technology tree technology without the peak.

Therefore, Zheng Ren is in awe, but he has to stay away.

This is not your own world, nor is it your own technology tree.

However, when I came to Nanyang, I was inevitably exposed to these strange things.

Zheng Ren looked at the surrounding environment and confirmed that it was the system space, not the outside.

This time he didn't have extracorporeal circulation and started dissection directly.

Opening the heart, Zheng Ren carefully stabbed a small hole with the lancet, and then stuck the oval forceps in.

Test subject, death.

Zheng Ren used oval forceps to clamp it in a mess, and finally confirmed that it was fine, so he dissected the right atrium of the test subject.

There was a lot of bleeding inside, a thin line of insects were crushed, and mixed with other messy tissues.

This time Zheng Ren is fine. The system did not prompt the surgeon to die, but the operation failed.

Zheng Ren was sure that it must be the problem of this little bug, which led to the strange prompt of the craftsman's death.

He calmed down and had another operation, but this time he honestly only had the operation and did not touch the "big watermelon".

The surgery is completed at 95%.

Zheng Ren completed an extremely complex operation by himself. It is good that the system can give such a high evaluation.

Back to reality, Zheng Ren heard the sound of a flat car coming from the corridor.

The flat car is of good quality, better than those of Haicheng and 912. The ground is also flat and the sound is very small.

Although it is called the National Hospital, it is an absolute private hospital. All kinds of equipment are prepared for wealthy people, regardless of cost.

To be honest, Zheng Ren is a little envious.

"Su Yun, Lao He, you guys are ready first. I'll go and explain something to the patient's family." Zheng Ren said.

"Hey, why are you doing sneakily?" Su Yun was obviously dissatisfied with Zheng Ren's actions and nagged.

Zheng Ren looked at Xie Yiren carefully and forced a smile. Fortunately, he was wearing a sterile mask in the operating room, and he couldn't tell how reluctant his smile was.

Xie Yiren smiled slightly, and Zheng Ren felt that the world is very warm now.

Walking out of the operating room, Zheng Ren saw Chu Nuan Sai half-sitting on the flat car, with more than a dozen doctors and nurses pushing him over.
Chapter completed!
