Laparoscopy has a great advantage for bystanders of the operation. The bystanders and the surgeon can see the same surgical field.

This is a very important point.

For conventional traditional surgery, even if the most advanced panoramic high-resolution camera is used, it is impossible to see all the scenes seen by the surgeon.

After all, the range of the camera is limited, and during the operation, problems may not always occur within the scope of the surgical field. Sometimes, the surgeon may make a surgical decision based on conditions outside the infusion range, and it may not even be based on the observation.

If you arrive, you may be able to touch it...

In contrast, endoscopic surgeries such as laparoscopy or arthroscopy do not involve so many conditions outside the surgery.

Whatever scene is displayed on the screen of the laparoscope is what the surgeon sees. Bystanders will not see any more or less than the surgeon.

If you just take a casual look, this difference may not matter.

However, if you really want to learn a surgical technique, the characteristics of laparoscopy and other endoscopes are very useful.

What you see is what you get, eliminating countless doubts and guesses.

However, at this time, the operating room No. 3 of the Emergency Center of Yunhua Hospital was filled with doctors who were full of doubts.

"Is it really a bloodless magic field?"

"It can't be said that it is completely bloodless..."

"Where's the blood?"

"What I just sucked away..."

"It doesn't matter what is sucked away, this is the bloodless magic field!"

Before Ling Ran could say anything, the doctors had already divided into three groups: left, middle and right, and started a heated discussion.

The term "bloodless surgery" is the highest state for surgeons, and it is a concept close to Confucian sanctification.

At present, except for a few types of surgeries, it is impossible to achieve a completely bloodless surgical field.

However, the process of surgeons constantly approaching this goal through various methods is just like the Confucian pursuit of sanctification, which is constantly moving forward, never stopping, and striving for excellence.

As for the benefits of "bloodless magic field", they are endless.

In the words of Halsted, the proposer of bloodless surgery: Only adequate exposure and careful hemostasis can give surgeons the necessary calmness, allowing them to think clearly and operate in an orderly manner on the operating table.

However, Halsted was a master of surgery in the late 19th century. He proposed this goal, but its implementation was a long process.

At present, the technology of extracorporeal circulation can achieve a relatively perfect bloodless surgical field.

Minimally invasive surgery can partially achieve a bloodless surgical field, but it is not 100%. In fact, not only is it not 100%, but the true bloodless state may not even be 1%.

It should be said that in addition to extracorporeal circulation technology, minimally invasive surgery is only one of the prerequisites to achieve bloodless surgical field.

Knowledge of anatomy and a little bit of luck are essential.

Even with the medical power of electrosurgical machines now, we cannot just electrocute small blood vessels when we see them. The result of doing so will only damage the patient's body.

The best thing to do is to avoid all kinds of blood vessels.

And this is actually the most incredible part. Human bodies are different. Different people have different blood vessels in terms of location, length, thickness, density, etc. To avoid all blood vessels, the naked eye alone is not enough.

judgmental.

Fortunately, the hole made by laparoscopy is very small, and even if a little blood flows out, it can be sucked away.

Of course, the hemostasis operation must be fast and accurate, and this is what Ling Ran is good at.

"The mesangium is open."

"Cut."

"Preparing to remove the appendix."

Ling Ran's voice sounded like a whisper.

Professor Huang couldn't help but glance at Ling Ran. If it were the students under him, they would be scolded first just for reporting so quickly.

Most surgeons can actually perform surgeries very quickly.

But if you want to do it well and quickly, it's not that easy.

The term "make mistakes while busy" is not a joke.

The most typical example is driving a vehicle at 20 kilometers per hour, 40 kilometers per hour, 80 kilometers per hour, or 120 kilometers per hour. It is definitely becoming more and more difficult to balance control and safety.

The various factors that need to be taken into consideration when driving are probably not as many as those that doctors need to consider during surgery.

Therefore, if Professor Huang heard that his students were deliberately pursuing speed, he would definitely throw out all the curses he had prepared.

However, Ling Ran did not show any "deliberate" appearance.

Professor Huang looked at Ling Ran's movements and felt fascinated. He thought unconsciously: Why don't I have such a student?

On second thought, Professor Huang couldn't help but shake his head: How could I have such a student!

"Professor Li's husband was operated on by Dr. Ling? No wonder he didn't die." A doctor suddenly said this, which shocked everyone.

"It's not that mysterious." Another doctor who came with him frowned and turned to ask Professor Huang: "Dr. Ling performed an emergency liver resection on him? Did you watch it?"

"It was finished when I went there," Professor Huang said honestly.

"how long."

"The liver part? I asked them, it only takes a few minutes." Professor Huang glanced at the other party and said meaningfully: "If you don't be careless, it will definitely take less than 10 minutes."

"This..." The doctor who spoke inhaled through his teeth: "Okay, I believe it."

There are not a few doctors who can perform high-level emergency liver resections. To say that they are rare, there is no shortage of surgeons who can perform bloodless surgical fields.

Several doctors from different hospitals calmed down and watched Ling Ran's surgery, with different thoughts running through their minds.

…

Ling Ran performed the appendicitis surgery at hand with a calm mind.

Since there was no need to perform a teaching surgery, Ling Ran no longer pursued speed and only considered completing the surgery safely.

Appendicitis is an extremely minor abdominal surgery. Because of this, there can be no mistakes at all.

Ma Yanlin finished the operation with a very uneasy state of mind.

Ma Yanlin, who has been a trained doctor for two years, has long been tired of seeing appendicitis surgery. What he really wants to do is to get started with it. No matter what he thinks of, a duck that reaches his mouth can actually fly!

"It's done." Ling Ran said habitually, and then said to Ma Yanlin, "I'll leave the rest to you."

"Yes." Ma Yanlin's expression suddenly became vivid. Although the duck flew away, it was good to leave one wing behind.

Ling Ran took off his mask and gloves and stepped on the air-tight door.

Professor Huang and others looked at each other and followed suit.

"Dr. Ling, is the operation finished?" Lu Wenbin happened to come out wearing hand washing clothes and saw a large group of people.

"It's done." Ling Ran nodded and introduced him as he walked out: "The patient's family members were involved in a car accident yesterday."

"Oh." Lu Wenbin then followed Ling Ran and continued walking out. He changed the topic without much enthusiasm and said, "I just went to meet the future family members."

"Huh?"

"oh……"

Yu Yuan asked louder: "Future family members? Are they going on a blind date?"

Lu Wenbin sighed and said: "The other party requires that the home must have two parking spaces and two cars. I can't get it, so there is no chance."

"A house and a car are not enough now?" Yu Yuan jumped up in surprise. She didn't even have a serious bicycle.

Lu Wenbin said "En" and said, "I'll go back and check the parking spaces. Hey, our parking spaces in Yunhua are expensive."

While speaking, a middle-aged woman in an Amash suit stood up from a group of doctors in white coats, looked at Lu Wenbin with a very experienced look, and said: "No matter how expensive it is, you have to buy it. Two parking spaces.

For now, it can be regarded as a necessity in life.”

"Then we don't need two..." Lu Wenbin complained.

The middle-aged woman in an Ama suit looked at Lu Wenbin and smiled: "You have to drive to work, so your wife shouldn't drive to work? If you want to park easily and go home early after work, shouldn't your wife stop the car easily and go home early?"

"I..." Lu Wenbin said helplessly: "Not many families buy two parking spaces now."

The middle-aged woman sneered at this: "You don't even have two parking spaces. If you go on a blind date, aren't you wasting people's time? If my daughter encounters such a situation, I will find trouble with the introducer on the spot."

Lu Wenbin was stunned for a moment, then turned around and took out his mobile phone, clicked on the group "Artiodactyl", and sent a text: "Pre-orders will open tomorrow, and you will get 400 for every 2,000 you spend on your membership card!"

After his message was sent out, WeChat exploded instantly.

Lu Wenbin recovered with pain and joy.

Listening to the conversation between the two, Yu Yuan couldn't help but sigh: "It seems like Dr. Ling should buy a parking space as soon as possible."
