Chapter 210

After receiving Xiao Chenguang's affirmation, Xu Guoqiang's eyes flashed with surprise.

He knew that Xiao Chenguang had solid theory and rich experience, but 3D reconstruction technology was not something that ordinary people could do.

It required image comparison, combined with the brain's algorithm, simulation and reconstruction, and finally found a breakthrough point for surgery.

There are many difficulties in this, the most important of which is that the simulator must have a strong sense of spatial three-dimensionality and solid anatomical ability.

"Reconstruction is not that complicated. I will look at the film and locate it under the microscope, and Teacher Xu will help to mark it."

"Will it work?" Xu Guoqiang was a little worried.

He went to study laparoscopy before, and was fortunate to see the big guy use it on the stage.

It was quite smooth at the beginning, but later, almost every time he did it, he needed to rest for a few minutes, and even at the end, he needed to pull the oxygen cylinder and breathe oxygen while doing the surgery.

After all, the brain power consumption was too great, and the operation had to be controlled. After a long time, the side effects of dizziness and vertigo were revealed.

"No problem, there are only a few difficult points in the operation, just pass them one by one."

Xiao Chenguang spoke in a relaxed tone, as if he was talking about something very ordinary.

In fact, before he went on stage in his later life, he often did 3D reconstruction, but it was all done on computers.

But the computers in the 1990s were not good-looking or practical, and the price was very expensive. The algorithms were limited, and it was really not as reliable as calculating by yourself.

This method is actually a bit like a scientific competition program that Xiao Chenguang later loved to watch.

The most impressive one is the scene of Wang, who has a parrot on his shoulder, using a 300,000 folding fan to suppress his daily life.

If he chooses to be a doctor, he will definitely leave a strong mark in the medical community.

The two people on the stage talked about 3D reconstruction, and their words were all about surgical details.

The other surgeons on the stage, including Shen Yiwei, were dumbfounded.

3D reconstruction, is that done by humans?

How can you simulate surgery based on the few films on the film light?

The textbook only mentioned a few words on the additional pages. After all, it is too difficult. Even the editors think that it is unrealistic to do it.

But why do they say it in a very orderly manner? Even Xiao Chenguang, who is the hand holding the camera, has already started the operation.

"Come on, check the camera and prepare for laparoscopic radical resection of gallbladder cancer."

"Anesthesia, check the drugs, and observe the patient's vital signs."

"Instruments, prepare for electrocautery with separation forceps, and bring the negative pressure suction device."

Xiao Chenguang stood on the stage and instantly turned into an all-round assistant.

Anesthesia, inspection, and instruments, under Xiao Chenguang's instructions, also began to act.

Everyone followed the steps and did their own work. The originally messy operating table immediately became orderly.

Xu Guoqiang looked at the scene in front of him, and the familiar feeling came to his heart. It seemed that only with Xiao Chenguang, his operation would become so smooth.

"Teacher Xu, let's start with the simplest gallbladder triangle."

Xiao Chenguang looked at the film on the spotlight, his brain running at high speed. The lesions and tissue structures shown by the PET and CT films gradually overlapped, rotated, and reconstructed in Xiao Chenguang's brain.

Then, the abdominal lens in his hand, which had not moved, followed the patient's bulging abdominal cavity and began to explore inside.

The picture on the screen was still changing, and in the blink of an eye, it came to an area with very serious adhesions.

"Is this the gallbladder triangle?"

Xu Guoqiang recognized it for a long time and asked uncertainly.

"Yes, according to the three-dimensional reconstruction of the film, this area is the gallbladder triangle."

Xiao Chenguang said lightly.

Faced with the answer, Xu Guoqiang looked at the screen carefully again. The tissue area, which was like a fog, seemed to be peeled off by hand under the rotation of Xiao Chenguang's lens, revealing the key points inside.

The gallbladder duct, the common hepatic duct, the visceral surface of the liver...

The structures that were very familiar to him before came into view, and Xu Guoqiang couldn't help but get excited.

"It's really the gallbladder triangle, Xiao Xiao, you are amazing."

In fact, from beginning to end, the difficulties of this operation, in the final analysis, are only two.

First, the invasion of the tumor leads to unclear anatomical structure and difficulty in determining the approach.

Second, the operation is difficult and difficult to operate. Freeing and segmenting can easily damage important blood vessels and cause massive bleeding in the body.

Because it is difficult to distinguish the tissue structure, this operation was performed with hesitation.

After all, if even the first point cannot be solved, and you don't know where to start, what kind of cancer radical surgery can you talk about.

Now, with the three-dimensional reconstruction technology simulated by Xiao Chenguang, the patient's entire abdominal cavity structure is displayed to everyone under his lens.

The operation finally has the motivation to continue.

"How did he do it? Is it because of the 3D reconstruction technology mentioned by Director Xu?"

"Maybe. We tried so hard before, but we couldn't find this area. Doctor Xiao found it in a few seconds. He is really amazing."

"This technology is so powerful. I really want to learn it. I wonder if I can ask him for advice after the operation."

The doctors in the audience were excited when they saw this scene.

When the theory in the textbook is used in practice, everyone who graduates from medical school will have a magical feeling.

"This... is a coincidence."

Shen Yiwei in the corner didn't care about the role of the invisible man this time. He instinctively leaned forward and stared at the screen intently.

The operation on the stage was still continuing. Under Xiao Chenguang's control, the cancerous tissue adhering to the gallbladder triangle was being freed bit by bit.

Xu Guoqiang controlled the separation forceps and grasping forceps, marveling while operating them.

In the past, as a mirror holder, there were many areas that he did not dare to explore, but now Xiao Chenguang turned a blind eye, and the camera moved around in his abdomen effortlessly.

And he can also rely on his unique advantages to perform surgeries quickly.

Is this the advantage of 3D reconstruction?

Xu Guoqiang didn't know, but now he couldn't care about it. He was feeling vaguely excited and just wanted to finish the operation quickly.

As long as the patient can get off the stage safely, minimally invasive surgery will be possible.

In front of so many people, Shen Yiwei even did not hesitate to show off as the dean to promise him, and he would definitely not regret it unless this guy lost his face.

When Corey is established and Xu Guoqiang becomes the director, he will no longer have to be constrained by Shen Yiwei. I am very excited no matter what I think.

The operation continues.

Xu Guoqiang worked hard and concentrated on the peeling triangle area, but at this moment, Xiao Chenguang's voice rang out.

"Teacher Xu, the common hepatic duct can be left until the end. The cancerous tissue in the liver area can be separated first, which will reduce the patient's bleeding volume."

As soon as these words came out, the instrument in Xu Guoqiang's hand froze.

"Is there a problem?"

Xu Guoqiang blurted out that according to the surgical procedure, the common hepatic duct should be exposed first. Why did Xiao Chenguang ask him to dissociate the liver area first.

"Yes, behind the common hepatic duct, there is a hidden feeding blood vessel hidden in the liver area. If the common hepatic duct is freed first, there will be some trouble."

Xiao Chenguang turned the camera and saw a blood supply buried in the liver area, just behind the common hepatic duct. If he didn't observe it carefully, it would definitely cause massive bleeding when it came loose.

call……

When Xu Guoqiang saw this, he took a deep breath, and even everyone in the audience couldn't help but look at each other in shock.

For their surgeons, what they fear the most is these hidden blood vessels that are invisible and intangible.

If Xiao Chenguang hadn't reminded him, the patient would have been cold on the spot if the scissors were removed.

"But this blood vessel cannot be reached with separation forceps or long scissors."

As one of the first laparoscopic surgeons in the province, Xu Guoqiang is more experienced than the group of people in the audience.

He suddenly discovered that no matter what angle he changed, the instrument in his hand could not directly bypass the common hepatic duct and contact the feeding blood vessels hidden behind it.

As a result, even if the cancerous tissue in the liver area is freed, the operation cannot be completed.

Seeing that Xu Guoqiang was a little anxious, even the atmosphere in the operating room became tense.

"Teacher Xu, didn't your department just get a rotary abdominal instrument? It's just in time to use it now."

Xiao Chenguang's voice, as plain as water, slowly sounded in the operating room.

yes!

Only then did Xu Guoqiang remember that someone seemed to have come here specifically to promote endoscopic equipment two days ago, and Director Shen had announced this at that time.

But how did Xiao Chenguang know?

"Qin Yong from Great Wall Medical is the person who picked me up tonight. Their company's products."

Seeing Xu Guoqiang's doubts, Xiao Chenguang explained.

"Great Wall Medical, Qin Yong?"

Although they didn't know who this person was, as Xiao Chenguang mentioned it, everyone present silently recorded the name in their hearts.
