Chapter 448： Kind (1/2)

? Laparoscopy has a great advantage for bystanders of surgery, that is, bystanders and surgeons can see the same surgical field of vision.

This is a very important point.

Changing to conventional surgery, even with the most advanced panoramic high-resolution camera, it is impossible to see the entire scene seen by the operator.

After all, the scope of the camera is limited, and during the operation, the problem is not always within the scope of the surgical field. Sometimes, the doctor of the main surgeon may make a surgical decision based on the situation outside the infusion range, not even looking at it. Yes, it may be felt ...

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

In the screen provided by the laparoscope, what scene is displayed, what scene is seen by the chief surgeon, and bystanders will not see a little bit more or less than a little bit.

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

However, if you really want to learn a surgical technique, this characteristic of endoscopes such as laparoscopy is very useful.

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

However, at this time, the operating room 3 of Yunhua Hospital's Emergency Center was full of doctors in doubt.

”Really bloodless?”

”It can't be said to be completely bloodless ...”

”Where is the blood?”

”It was just sucked ...”

”It doesn't matter what you suck, this is the bloodless field!”

Before Ling Ran spoke, the doctors had been divided into three groups: left, middle, and right, and heated discussions took place.

The term ”bloodless field” is the highest state for surgeons, and is a concept of sanctification close to Confucianism.

For the time being, it is impossible to achieve a completely bloodless surgical field except for a few operations.

However, the surgeon's constant approach to this goal in various ways, just like the Confucian pursuit of sanctification, is constantly advancing, never stopping, and improving.

As for the benefits of the ”Bloodless Field”, it is endless.

In the words of the author of bloodless surgery, Holstead said: Only sufficient exposure and careful hemostasis can give surgeons the necessary calmness, so that they can think clearly and operate on the operating table.

However, Holsted was a surgeon in the late 19th century. He proposed this goal, but the implementation is a long process.

At present, it is the technique of extracorporeal circulation, which can perfectly realize the bloodless operation field.

Minimally invasive surgery can partially achieve bloodless operation, but it is not 100%. In fact, not only is it not 100%, it can really reach the bloodless realm, maybe even less than 1%.

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

An understanding of anatomy and a little bit of luck are essential.

Even if there is a medical spirit like an electric knife now, I can't see the small blood vessels and then call off the electricity. As a result, it only damages the patient's body.

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

This is actually the most incredible part. The human body is different from the human body. Different people have different positions, lengths, thicknesses, and denseness of blood vessels. To avoid all blood vessels, the naked eye is not enough. Judging.

Fortunately, the hole to be punched by the laparoscope is very small.

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

”The mesangium is open.”

”Cut.”

”Ready to get the appendix.”

Ling Ran's voice sounded like a sound.

Professor Huang could not help but take a look at Ling Ran. If it was replaced by a student under his hand, the speed of the report would be scolded first.

Most surgeons can do surgery quickly.

But what you want to do is good and fast, it is not so easy.

The word ”wrong during busy hours” is not for fun.

The most typical example is driving. Vehicles traveling at speeds of 20 kilometers, 40 kilometers, 80 kilometers, and 120 kilometers per hour. It must be more and more difficult to balance control and safety.

And there are many factors to consider when driving. I am afraid that there are not many factors that doctors need to consider during surgery.

Therefore, if Professor Huang hears his students deliberately pursue speed, then he is prepared to scold others and must throw it out.
