Chapter 1538 Microscopic Teaching

If there is a technology that can reduce the damage of patients, perhaps early cancers and precancerous lesions can be stopped and stopped.

As a doctor, this is also Director Wei's dream.

"Xiaocao, listen carefully." Director Wei said in a low voice but seriously.

Quan Xiaocao nodded vigorously.

For Director Wei, Quan Xiaocao is just like her name, insignificant. But in a sense, she represents the future!

The specific equipment fixed the general teacher's intestines. Zheng Ren felt that Su Yun was a genius.

This equipment is really suitable for demonstration. Although the remaining colon is only 20 cm, it does not affect the operation of colonoscopy and the demonstration of ESD technology at all.

This time he didn't come, and the patient didn't know whether he was diagnosed with thymoma or whether he had undergone surgery. As for whether the operation would be successful, Zheng Ren didn't think about it.

The rising star of cardiothoracic surgery in the imperial capital can't even do a thymoma, that's a joke.

Zheng Ren took a deep breath while thinking about the misdiagnosed operation that he had blocked.

He exhaled the turbid air, put on the microscope, and took out a new pair of sterile gloves to put on.

"microscope?"

"Yeah, when I was an apprentice, I saw a teacher who did microsurgery."

"Isn't it endoscopic mucosal dissection? Why wear a microscope?"

When the students saw Zheng Ren put on the equipment, those who knew him began to show off their knowledge, and there were many discussions.

Principal Zhang turned sideways, approached Vice President Yuan, and asked, "Lao Yuan, what is Dr. Zheng trying to do with a microscope?"

Vice President Yuan didn't know either, but someone around him knew.

"Director Luo, why does Dr. Zheng wear a microscope?" Vice President Yuan asked.

"That's right, Boss Zheng performed an ESD operation two days ago to remove a precancerous lesion that invaded the muscle layer. Normally, the current ESD technology cannot remove the diseased tissue that invades the muscle layer, but Boss Zheng uses The microscope cooperates with the colonoscope to do it." Director Luo looked ahead, looked straight at Zheng Ren, and explained to the dean.

"Surgery taboo?" Vice President Yuan was also a little surprised.

"It's a taboo for surgery under the existing technology. Boss Zheng used technology to overcome this difficulty." Director Luo saw that Zheng Ren was ready, and hurriedly defended, and then stopped talking, but looked at Zheng Ren intently. operation.

At this moment, Vice President Yuan was disliked.

As Zheng Ren was ready, there was a huge change on the big screens on both sides.

The image that appeared on the screen was the screen of the endoscope and Zheng Ren was wearing white clothes and holding a colonoscope.

The two merged into one, very natural, not contrived at all.

"The colon is divided into four anatomical structures: mucosa, submucosa, muscularis, and adventitia. We have just talked about this." Zheng Ren's voice echoed in the 2 teaching, and more and more students poured in at this time.

The aisles on both sides were already full of people.

The group of people who came first were extremely lucky, at least they had a better position.

Because of Su Yun's thoughtful design, there is no blind spot in the 2 teaching, and every corner can see the most detailed operations on the screen.

This technology has only been carried out clinically for a few years, and those who can peel off the gastric mucosa are considered big hands.

Using a colonoscope to cut appendicitis is even more of a feather in the sky.

Not to mention the students of Imperial Medical University, even the chief directors of 912, Director Wei and Director Luo, did not know much about ESD surgery.

The students were watching the liveliness, while Director Luo and Director Wei were watching the doorway.

Professor Stephen Jones was silent, watching Zheng Ren's movements quietly.

"Xiao Cao, have you seen the anatomical structure just now?" Director Wei asked.

"I see clearly!" Quan Xiaocao said excitedly, "Boss Zheng's anatomy is very detailed, and it's hard to understand."

Director Wei shook his head. It seemed that Quan Xiaocao was really excited. Usually, she would just lower her head and talk to hide her shyness.

At this time, Zheng Ren had already started the operation, and Director Wei did not continue to speak, but watched intently.

operate……

As soon as you get started, it is microscopic manipulation, which is Director Wei's technical blind spot.

Gastrointestinal surgery does not require a microscope at all.

It was not used before, not now, in the future... Director Wei sighed inwardly as he watched Zheng Ren's operation.

In the future, it's hard to say.

The forceps in front of the lens bluntly dissect the colonic mucosa, and then the mucosa is dissociated little by little.

The field of vision is Zheng Ren's microscopic field of vision. The students who had only a broad concept of the colonic mucosa before, but had no actual impression, exclaimed one after another in the 2 teaching.

At the same time, in the bodies of Director Luo and Director Wei, the hormone levels rose, fell, and rose again just like the exclamations of the two teachers.

The students were watching the liveliness, but the two directors of 912 Gastrointestinal Surgery were watching the real way.

The technique of blunt dissection is extremely delicate, fast and gentle, and the mucosa and submucosa are quickly separated from the muscularis.

This gross specimen is a normal human tissue with no lesions.

But the two directors knew that with such delicate separation, precancerous lesions and the like could not stop Boss Zheng's methods.

If the tumor is too large, it is beyond the scope of ESD surgery and can be surgically removed.

That is another concept.

"Director Luo, do you know how to use a microscope?" Director Wei asked Director Luo next to him while feeling emotional.

"No." Director Luo was a little distressed. The serious ESD surgery to strip the gastric mucosa can't be considered perfect, let alone the more advanced surgical procedures of mucosal stripping under the microscope.

Director Wei was relieved and smiled slightly.

Director Luo felt a little strange, his eyes fixed on the screen, watching Zheng Ren peel off the colonic mucosa and submucosa.

The technique was so subtle that Director Luo was deeply moved.

"What do you mean?" he asked casually.

Director Wei just smiled and watched Zheng Ren's operation on the big projection screen seriously, and did not answer Director Luo's question.

His hand moved slightly, simulating Zheng Ren's operation. But Director Wei knew that it seemed that he should be able to do it, but it was only the appearance.

This is a micromanipulation, not a manipulation under the naked eye.

If you wear a microscope yourself, you will never be able to perform such skilled micro-manipulation in a small space.

He is a little sad, he is still old, and his mastery of new technologies must be much worse than that of young people.

When I go back, I will put Quan Xiaocao in Boss Zheng's team, Director Wei thought to himself. Or go out of the clinic by himself in the future, and find some patients for ESD surgery. Quan Xiaocao will follow all the operations.

I can't believe that there is no one in gastrointestinal surgery to learn new techniques.

Even if it is to be raised, it is necessary to raise a big one who specializes in ESD surgery. Otherwise, gastrointestinal surgery will be as lonely as cardiac surgery in a few years.
