Chapter 448: Gentle

? Laparoscopy has a great advantage for surgical bystanders. The bystanders and the operator can see the same surgical field of view.

This is a very important point.

In conventional traditional surgery, even if the most advanced panoramic high-resolution camera is used, it is impossible to see all the scenes that the operator sees.

After all, the range of the camera is limited, and during the operation, the problem is not always within the range of the surgical field. Sometimes, the surgeon may make a surgical decision based on the situation outside the range of the infusion, and it may not even be based on the observation. Got it, maybe touched it...

In contrast, endoscopic procedures, such as laparoscopy or arthroscopy, do not have as many surgical field conditions.

What scene is displayed on the laparoscopic screen, what the surgeon sees is exactly what the surgeon sees, and the bystanders will see neither more nor less than the surgeon.

If you just look at it casually, this difference may not matter.

However, if you really want to learn a surgical technique, the characteristics of endoscopes such as laparoscopes are very useful.

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

However, at this time, operating room No. 3 of the emergency center of Yunhua Hospital was full of suspicious doctors.

"Is it really a bloodless wild?"

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

"Where is the blood?"

"Just sucked away..."

"It doesn't count if it is sucked away, this is the bloodless wild!"

Before Ling Ran could speak, the doctors had already divided into three factions: left, middle and right, and heated discussions started.

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

For now, it is impossible to achieve a completely bloodless surgical field of vision except for a few types of surgery.

However, the process of surgeons constantly approaching this goal through various methods is just like Confucianism’s pursuit of holiness.

It is constantly advancing, never stopping, and striving for perfection.

As for the benefits of the "bloodless wild", there are too many to mention.

In the words of Halsted, who proposed bloodless surgery, only sufficient exposure and careful hemostasis can give surgeons the necessary calmness, so that they can think clearly and operate in an orderly manner on the operating table.

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

At present, that is, the extracorporeal circulation technology can perfectly realize the bloodless surgical field.

Minimally invasive surgery can partially achieve a bloodless surgical field, but not 100%. In fact, not only is it not 100%, but even less than 1% of those who can truly reach the bloodless state.

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

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

Even with the medical air of an electric knife now, you can't just electrocute when you see a small blood vessel. The result of doing so will only damage the patient's body.

The best way is to avoid all kinds of blood vessels.

And this is actually the most incredible part. The human body is different from the human body. The position, length, thickness, density, etc. of the blood vessels of different people are different. To avoid all the blood vessels, the naked eye alone is not enough Judgmental.

Fortunately, the hole to be drilled by the laparoscope is very small, but a little blood flows out, and it is enough to suck it away.

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

"The mesentery is open."

"Cutting."

"Preparing to remove the appendix."

Ling Ran's voice sounded like a voice.

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

Most surgeons can perform operations very quickly.

But if you want to do it well and quickly, it is not so easy.

The term "mistakes in a busy schedule" is not just for fun.

The most typical example is driving. It is definitely more and more difficult to balance the control and safety of a vehicle with a speed of 20 kilometers per hour, 40 kilometers per hour, 80 kilometers, and 120 kilometers per hour.

As for the various factors that need to be considered in driving, I am afraid that there are still not as many factors that doctors need to consider in surgery.

Therefore, if Professor Huang hears that his students are deliberately pursuing speed, then he must throw out all the cursing baskets he has prepared.

However, Ling Ran did not appear to be "deliberate".

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

After thinking about it, Professor Huang couldn't help shaking his head: How could I have such a student!

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

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

"I finished it when I went." Professor Huang said honestly.

"how long."

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

"This..." The speaking doctor inhaled between his teeth: "Okay, I believe it."

There are not a few doctors who can perform high-level emergency liver resection. If it is rare, it is rare but a surgeon who can create a bloodless surgical field.

Several doctors from different hospitals calmed down, watching Ling Ran's operation, they each had different thoughts in their hearts.

...

Ling Ran performed the appendicitis operation at hand with a peaceful mind.

There is no need to do teaching surgery, Ling Ran no longer pursues speed, and only thinks about completing the surgery safely.

Appendicitis is a small abdominal operation that cannot be smaller. Because of this, there must be no mistakes at all.

Ma Yanlin finished the operation with an extremely uneasy attitude.

Appendicitis surgery, for Ma Yanlin, who has been a training doctor for two years, has long been tired of seeing it. What he wants to do is to do it firsthand. Wherever he thinks, a duck can fly!

"It's done." Ling Ran said habitually, and then said to Ma Yanlin: "Leave the rest to you."

"Yes." Ma Yanlin's expression suddenly became lively. Although the duck flew away, it is not bad to leave a wing.

Ling Ran took off his mask and gloves, and stepped on the airtight door.

Professor Huang and the others looked at each other, and they all followed suit.

"Doctor Ling, are you done with the operation?" Lu Wenbin happened to come out wearing a hand sanitizer, and saw a large group of people.

"It's done." Ling Ran nodded, and while walking outside, he introduced by the way: "The family member of the patient yesterday was involved in a car accident."

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

"Huh?"

"oh……"

Yu Yuan asked even louder: "Future family members? Go on a blind date."

Lu Wenbin sighed, and said: "The other party requires that there must be two parking spaces and two cars at home. I can't get them out, it's useless."

"It's not enough to have a house and a car now?" Yu Yuan jumped up in surprise, she didn't even have a decent bicycle.

Lu Wenbin said "En", and said, "I'll go back and look at the parking spaces. Hey, our Yunhua's parking spaces are very 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 experienced eyes, and said, "No matter how expensive it is, you have to buy it. Two parking spaces, For today's small families, it can be regarded as a necessity of life."

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

The middle-aged woman in the Amash suit looked at Lu Wenbin and smiled: "You have to drive to work, but your wife shouldn't drive to work? If you want to park easily after work and go home early, your wife shouldn't park 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. Isn't it a waste of people's time if you go on a blind date? If my daughter encounters such a situation, I will find trouble with the introducer on the spot."

Lu Wenbin was stunned, turned around and took out his mobile phone, clicked on the group "cloven hooves", and sent a text: "Tomorrow, pre-orders will open, and the membership card will be 2000 to get 400!"

His message was sent out, >

Lu Wenbin responded with pain and happiness.

Listening to the conversation between the two, Yu Yuan couldn't help but sigh with emotion: "From this point of view, Doctor Ling should buy a parking space earlier."

"Doctor Ling doesn't need it, our family has 6 parking spaces." The middle-aged aunt had a warm smile on her face.
