Time passed slowly, and in a flash, it was another week later.

Zhou Cheng was in charge of the operation, and Chu Hanbo, Fang Fang, and Yang Yifeng were watching. Chu Hanbo and Fang Fang watched intently, and Yang Yifeng couldn't help but yawn!

After Zhou Cheng quickly completed the treatment of the three mice, he gave up his position. However, it was not Chu Hanbo's position to take Zhou Cheng's position, but the direction.

After the director completed the disinfection and other operations very carefully, he stood at the main operating position. First, he looked at the various equipment on the simple operating table and the prepared micro-marking pens.

"Teacher Chu, Brother Cheng, Brother Yifeng, I'll start first. You should give me guidance at any time." Fang Xiang took a deep breath, then looked around and begged.

Chu Hanbo nodded and urged: "You start quickly, our time is very tight."

"Luo Yun will be in the lab over there at 11 o'clock at most. He won't give you too much time to practice."

This is the second batch of mice for batch animal experiments. The ones that Zhou Cheng operated before are currently, through CT quantitative comparison, the volume of bone tumor tissue is obviously much smaller than before.

But I still continue to monitor and observe the subsequent reactions, osteogenic reactions, recurrence, metastasis, etc. It will take time to slowly accumulate.

It was seen that it was effective, and the first time, Zhou Cheng performed it with imperfect auxiliary tools. Therefore, this time, Zhou Cheng already had access to more professional equipment.

Let them get started.

Experiments, operability and repeatability of surgery determine the value of an operation to a certain extent. If an operation cannot be repeated, then no matter how perfect it is, its value will be quite limited.

A good surgery that can be promoted is more objective.

He no longer hesitated in the direction and began to make marks honestly. Although Zhou Cheng had already listed a lot of information about the direction of blood vessels and the positioning piles of mouse legs, he was the first to contact him. The best way is to follow the steps step by step and make progress steadily.

OK.

The reason why Direction was the first to get started is because Direction’s brain is flexible enough. Although the suggestions he occasionally gives are out of tune, he is really good at thinking.

In fact, the first choice was Yang Yifeng, but Yang Yifeng's spirit has been quite sluggish recently!

"Steady your hands, don't shake them." Zhou Cheng saw that the hand in the direction was still a little unstable, so he immediately opened his mouth and stopped.

The direction suddenly shook even more violently, and then after calming down for a while, the slightly trembling hands became extraordinarily steady!

Zhou Cheng's words not only made Fang Fang feel relieved, but Yang Yifeng also cheered up and focused his gaze on the operating table with an expressionless face.

Fang Fang was very proficient in the surgical plan. Zhou Cheng demonstrated it no less than a hundred times, and the theory was quite thorough. Therefore, Fang Fang quickly made the marks and then reviewed the location of the tumor on this mouse.

Then, without hesitation, he identified the mouse's leg nerve and started the block. The immobilized mouse's affected limb slowly stopped trembling. This blocked its sensory and motor functions, and anesthetized it.

Some muscle relaxants are added to the medicine.

After anesthesia, Fang was disinfected again, and then he nervously opened the skin of the mouse's leg. Zhou Cheng chose to blindly enter the popliteal artery, while Fang took the second best option and chose to partially open it.

The skin and subcutaneous tissue were carefully incised, and then the epimysium was exposed. The epimysium was bluntly broken open, and then a blood vessel with a larger diameter was carefully found from the popliteal fossa.

It was the popliteal artery. When he saw its diameter, he suddenly took a breath of cold air: "Brother Cheng, you usually do this blindly, inserting into this artery, and then into its branches?"

Chu Hanbo also glanced at Zhou Cheng: "The skills are so close that I won't let you repeat such an operation. There are auxiliary equipment, so don't waste any more time. Four minutes have passed since you did this."

Not daring to be careless, he quickly clamped the proximal end of the heart and then used a syringe to break open the blood vessel. Then he slowly opened the proximal vascular clamp and restored the blood flow. He did not see much blood being broken from the pinhole.

out.

Then, through the special cannula tissue, the one-way sheath tissue was slowly placed into the popliteal artery. In an instant, the blood that slowly seeped out completely disappeared, proving that the sheath placement was successful.

After carefully injecting some markers to allow the arteries to be roughly visualized, the direction took the opportunity to clamp the surrounding meridians so that the developed markers would not flow back into the body's blood system.

After that, everyone exited and took pictures again. After processing by the imaging system, the general signs and trends of the blood system of the lower limbs were obtained. Among them, the place with the most abundant blood vessels was undoubtedly the location of the tumor tissue!

This is to simplify the surgical operation and reduce the difficulty of the operation. The simplified surgical plan designed by Zhou Cheng and others based on the existing equipment and technology is equally effective, but the process is more complicated and lengthy.

But as long as the goal is achieved, the speed of the operation does not need to be so concerned. The operation time can be shortened by improving proficiency.

While reading the film carefully, Xiang Fang frowned: "Isn't this blood vessel network too rich?"

"No wonder we don't choose precise targeted blockade, but perform extensive vascular blockade."

Zhou Cheng said: "The tumor's habits and growth area are inherently difficult to control and cannot be repeated. Naturally, it is impossible to directly operate its nutritional blood vessels as it is prescribed to die."

"Then continue to push the catheter in to the appropriate position, and then continue to adjust the positioning, and then you can start the block operation." Zhou Cheng continued to repeat the idea of ​​​​the operation.

The idea is certain, but the operation is very difficult, and the direction is not required to be achieved overnight.

After finishing speaking, he looked at Yang Yifeng. Yang Yifeng could not take his eyes away. His eyes seemed to be deep, but in fact they were a bit blurry. It seemed that he had not had much rest recently.

Yang Yifeng also noticed Zhou Cheng's gaze and shrank his neck.

I just regret that my hair is too short and cannot stop the fruits Liu Shiyu grows.

If it weren't for this action, Zhou Cheng would not have paid attention to Yang Yifeng's neck under his old face. After seeing it, Zhou Cheng cursed loudly.

Second Austrian.

He's so young, but he still imitates other people's fun...

The direction was still trembling, pushing the connecting catheter inside, and then constantly taking pictures and positioning. People kept going in and out of the operating room.

Finally, after seven minutes, Fang Xiang's forehead was so tense that he saw the positioning stakes were ready and said: "Brother Cheng is such a pervert. It was difficult for me to get into the position even when I was positioning. He actually

It can be found accurately."

However, he didn't say much, and then quickly added a longer catheter appropriately and entered the farther end of this catheter.

After that, the direction controlled the syringe of one of the catheters and injected a certain amount of blocker. It can be seen that due to the filling of the blocker, the flow of the artery was blocked and the lumen of the blood vessel became slightly larger.

part.

However, there are still other passages surrounding it, so it is not completely closed.

After that, the direction immediately followed the same technique and spent more than ten minutes to find the exit of the nourishing artery network and block it!

Operation completed!

"It's done!" Fang Fang looked at Chu Hanbo happily, his face full of surprise.

Chu Hanbo said: "More than twenty minutes have passed now. If Zhou Chenglai had done the operation, he would have completed two units. Your half of the operation has not been completed. What can you be happy about?"

Hearing this, Xiang Xiang's face collapsed and his excitement subsided: "Teacher Chu, how about you come and give it a try?"

Chu Hanbo immediately shut up and said nothing!

If he had the ability to do this, he would have gone to it long ago. However, he has not been in a clinic for a long time, so he may need a period of familiarity if he is a little bit new.

Obviously, he has not passed this familiarization period yet.

"Director, don't worry about arguing with Senior Brother Chu. You are in charge now. Don't let any other factors affect your mood and operations. Continue to the next step." Seeing that the situation was wrong, Zhou Cheng put the topic on the right track.

Next step!

It is to extensively fill the nutrient artery network with blockers. This will block the nutrient artery network blocked by bone tumors to the greatest extent. This can also prevent blood vessels from causing blood problems even if new collateral circulation is established.

Reconnect!

It's impossible to starve them to death.

This step may seem simple, but it is actually difficult to operate, because the relatively large entrances and exits of the nutrient artery network are blocked at this moment, and blood cannot flow, leaving only small collateral circulation and low blood flow.

In order for the blocker to completely fill the entire lumen of the nutrient arterial network, most of the blood inside needs to be emptied to make way for the blocker.

This is not easy to operate.

It is easy to directly destroy the nourishing artery network. After that, the operation will be directly GG.

This kind of thing has not happened before. The last time, Luo Yun used too much force during the experimental operation and directly squeezed and exploded the blood vessels inside!

If the mouse explodes, it won't be a big deal, but when it actually enters the human body, if such a situation occurs, it will be a very serious matter.

Having learned from Luo Yun's mistakes, he took a more cautious direction.

I didn't dare to exert force, and then I found that I seemed to have no strength, and there was a lot of resistance when pushing in the blocking object.

"Just because you don't use too much force doesn't mean you shouldn't use force."

"But you have to use continuous force, otherwise after a while, the blocker will dry up and become a blind cavity. If you want to go into the blind cavity again."

Before Zhou Cheng finished speaking, the direction said: "Brother Cheng, it has solidified. It cannot be beaten."

The direction also tried to use force, and sure enough, I saw a pushing back feeling like the syringe was blocked and the air was squeezed out.

Zhou Cheng sighed: "Then there is no other way. The current blocking objects can only have such properties. It is almost impossible to temporarily improve the quality of the blocking objects."

"You should finish the operation." Unexpectedly, after so long preparation, the direction still failed, and it also fell to the place where Luo Yun had operated before.

The direction quickly moved away from the operating table, and if he continued, the result would definitely be the same as Luo Yun's last operation.

At this time, Luo Yun happened to come from outside. Looking at the complicated tools on the operating table, he knew that this operation was not done by Zhou Cheng.

"How was it? Was it successful?" Luo Yun turned around and asked, looking at Yang Yifeng.

Among these people, Yang Yifeng's operating level is the best and closest to Zhou Cheng. If it weren't for Yang Yifeng's recent poor state, Luo Yun would not have become the first loser.

"Teacher Luo, this time the operation was directional. During the process of blocking the nutrient artery network, the blocker was still allowed to partially solidify. The operation was not completed." Yang Yifeng quickly explained.

Luo Yun almost understood what he had encountered in the direction. He glanced at Zhou Cheng and complained: "Xiao Zhou, is there something wrong with your plan?"

"This kind of rapid coagulant is not suitable for such tiny arteries at all."

Zhou Cheng closed his eyes and thought for a moment. Luo Yun was just asking a question, not making an argument.
