After getting 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 really 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, he needed to rest for a few minutes almost every time he did it, 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 is too great, and the operation must be controlled. After a long time, the side effects of dizziness will appear.

"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 a computer.

But the computers in the 1990s were not good-looking or practical, and the price was very expensive. The algorithms were limited, so 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 classmate Wang with a parrot on his shoulder, using a 300,000 folding fan to suppress his daily life.

If he chose to be a doctor, he would 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 stage, including Shen Yiwei, were dumbfounded.

3D reconstruction, is that done by humans?

How could it be possible to simulate surgery based on just a few films on the film light?

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

But why did they say it so clearly? Even Xiao Chenguang, who was holding the camera, had 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.

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

"Maybe. We tried so hard before but couldn't find this area. Doctor Xiao found it in just a few strokes. 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 graduated from medical school will have a magical feeling.

"This... is a coincidence. "

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

The operation on the stage was still going on. Under Xiao Chenguang's control, the cancerous tissue adhered to the gallbladder triangle was being freed little by little.

Xu Guoqiang manipulated the separation forceps and grasping forceps, and he was amazed while operating.

Before, as a cameraman, he dared not explore many areas, but now Xiao Chenguang turned a blind eye and the camera moved around in the abdominal cavity without any effort.

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

Is this the advantage of three-dimensional reconstruction?

Xu Guoqiang didn't know, but now he couldn't care less After thinking about all this, I felt a little excited and just wanted to finish the operation quickly.

As long as the patient can get off the stage safely, there will be a chance for minimally invasive surgery.

In front of so many people, even Shen Yiwei did not hesitate to put on the role of dean to promise him, and he would definitely not regret it, unless this guy didn't care about his face.

When the department is established and Xu Guoqiang becomes the director, he will no longer be constrained by Shen Yiwei, and he is very excited no matter how he thinks about it.

The operation is still going on.

Xu Guoqiang tried his best and focused on stripping the triangle area, but at this time, Xiao Chenguang's voice rang out.

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

As soon as these words came out, Xu Guoqiang paused for a moment.

"Any questions? "

Xu Guoqiang blurted out that according to the surgical procedure, the common hepatic duct should be exposed first, so why did Xiao Chenguang let him free the liver area first.

"That's right, behind the common hepatic duct, there is a hidden 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 vessel buried in the liver area, just behind the common hepatic duct. If you don't observe carefully, it will definitely cause heavy bleeding during the freeing.

Huh...

Xu Guoqiang took a breath of cold air when he saw this, and even the people in the audience looked at each other in surprise.

For them, surgeons, the most feared thing is this invisible and intangible hidden blood vessel.

If Xiao Chenguang hadn't reminded him, the patient would have died on the spot with this scissors.

"But this blood vessel can't be reached with separation forceps or long scissors. "

As one of the first few people to perform laparoscopic surgery in the province, Xu Guoqiang had more experience than the group of people in the audience.

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

In this way, even if the cancerous tissue in the liver area was freed, the operation could not be completed.

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

"Teacher Xu, your department just got a rotating abdominal instrument, and it's just in time to use it now."

Xiao Chenguang's calm voice sounded slowly in the operating room.

Yes!

Xu Guoqiang then remembered that someone seemed to come here specifically to promote laparoscopic equipment a few days ago, and Director Shen had announced this at the time.

But how did Xiao Chenguang know?

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

Seeing Xu Guoqiang's puzzled expression, Xiao Chenguang explained.

"Great Wall Medical, Qin Yong? "

Although no one knew who this person was, when Xiao Chenguang mentioned it, everyone present silently remembered this name in their hearts.
