Different from normal tumor tissue, what we saw before is a part of the body. Although it is abnormal hyperplasia and pathological changes, it still belongs to a part of the body.

But in front of this big watermelon, it seems to have its own set of independent circulation system. The pedicle is the pipe, constantly wriggling... Wriggling

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

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

This is the normal way of heart blood circulation.

Zheng Ren thought of this because the beat of the big watermelon was inconsistent with the heart beat, which was much faster.

If it is a living thing, it should be in the left ventricle. In this way, it receives arterial blood and "nutrition" is more sufficient.

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

Is this an anaerobic organism that doesn't like oxygen?

I don't know whether it's because of long-time blood immersion or just like this. The color of big watermelon is dark red and disgusted with Ze Ze Ze.

Zheng Ren gently put his finger on the big watermelon to determine the time for the heart to beat once. It needs to beat 4-5 times.

It's really a strange thing. I don't know if the big pig hoof can perfectly simulate this guy.

According to the habit of surgery in the past, it must be blunt separation first, remove it from the right atrium with the least damage, and then open it after the operation.

The smallest hemostatic forceps were placed in his fingers. Zheng Ren put on a microscope and began to free the tissue at the edge.

Points, pulls, lifts, pinches, the entire big watermelon's pedicle is separated by Zheng Ren. It contains the intima with the right atrial wall and the lateral wall of the inferior vena cava, which are free and cut off together.

This is the principle of complete tumor resection. The periphery should always carry normal tissue. Otherwise, as long as there is a trace of tumor cells, recurrence is inevitable.

In Zheng Ren's opinion, this thing is completely tumor tissue, even higher than the "malignant" degree of tumor tissue!

Completely remove the tumor, the attached right atrial wall and part of the lateral wall of inferior vena cava, immediately switch to inferior vena cava intubation, and the operation field is clear after tightening the control belt.

Then Zheng Ren used autologous pericardial patch and inferior vena cava repair. Cut two pieces of pericardium and sew to repair the right atrium and inferior vena cava like a tailor.

It is simply that the operating box given by Dr. Charles has all kinds of equipment, and this problem can be solved without the smallest needle.

Continuous suture, check no active bleeding, Zheng Renchang breathed.

The operation is over here.

As for stitching, it's the work of an assistant. It has nothing to do with yourself.

The whole operation is much simpler than tricuspid valve tumor. Zheng Ren finished it smoothly at one time.

Instead of caring about the chest of the test body, he came to the side, held the "big watermelon" in his hand and observed it carefully.

Because there was no blood supply, the peristalsis of the two straws was much slower.

Zheng Ren felt that it was really intelligent, as if "big watermelon" was communicating with himself through sterile gloves.

Unfortunately, I can't understand it.

That frequency is not Morse code, nor is it any cryptosystem known by other Zheng Ren.

Cut it open. Zheng Ren holds the "big watermelon" in his left hand and cuts it with a knife in his right hand.

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 operator died.

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

Is this special? What's going on?

Zheng Ren was silly.

If the operation fails, it will fail. Why is there a prompt of death?

Time passed quickly. The first thing Zheng Ren did after he calmed down was to continue to buy surgery training time.

As the system operating room rose, he stepped directly in.

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

He knew that his guess was right. The space occupying lesion in the right atrium of chunouansai is not a myxoma at all, but an insect egg!

I just cut the eggs myself, and the insects inside ran out and killed myself.

What a special shape!

The sudden change of painting style made Zheng Ren uncomfortable.

The reason why he keeps a respectful and distant attitude towards some things of strange forces and gods is that Zheng Ren thinks these can be explained by science.

If you can't explain, it's that the technology tree hasn't reached that level.

It is difficult to use one technology tree to explain the technology of another technology tree.

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

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

However, when I came to Nanyang, I inevitably came into contact with these strange things.

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

This time, he didn't do cardiopulmonary bypass and began dissection directly.

Open the heart, Zheng Ren carefully stabbed a small hole with a willow blade knife, and then extended the oval pliers.

Test body, death.

Zheng Ren clamped the right atrium with oval pliers and finally determined that it was all right. Only then did he dissect the right atrium of the test body.

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

Zheng Ren was fine this time. The system did not prompt the operator to die, but the operation failed.

Zheng Ren determined that it must be the problem of this little bug that led to the strange hint of the death of the operator.

He stabilized his mind and had another operation, but this time he honestly only did the operation and didn't touch the "big watermelon".

The surgical completion rate was 95%.

For a very complex operation, Zheng Ren completed it alone. It's good that the system can give such a high evaluation.

Back to reality, Zheng Ren heard the sound of flat cars in the corridor.

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

Although it is called the National Hospital, it is a truly private hospital. All kinds of equipment are prepared for the rich, regardless of cost.

To tell you the truth, Zheng Ren is a little envious.

"Su Yun, Lao he, you prepare first. I'll explain something to the patient's family." Zheng Rendao.

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

Zheng Ren looked at Xie Yi very carefully and forced out a smile. Fortunately, in the operating room, wearing a sterile mask, I can't see how reluctant the smiling face is.

Xie Yi smiled back. Zheng Ren felt that the world was very warm now.

Out of the operating room, Zheng Ren saw Chunu Ansai half sitting on the flat car, and more than a dozen doctors and nurses pushed him over.

"Wait a minute, Mr. chunouansai. I have something to tell you." Zheng Ren stood in front of the flat car and blocked the way.
