Chapter 200 For the first time in the history of medicine, the concept of an inverted triangle is proposed

Zhao Peiru said, "I plan to improve in two aspects."

Everyone cheered up and listened attentively!
Professor Shu Yun winked at a deputy director next to him, and that person immediately went to close the door.

Everyone knows that the next step is the most critical part of the "Project Proposal"!

Zhao Peiru: "The first one is to improve the anastomosis. After the hepatic vein is cut horizontally, it is trimmed downward along the longitudinal axis of the vena cava to form an "inverted triangle" of corresponding size."

"In this way, the anterior wall of the recipient's retrohepatic vena cava is trimmed to an "inverted triangle" incision of the same size as the donor liver's retrohepatic inferior vena cava."

"To facilitate the anastomosis of recipient and donor."

Among the crowd, those with a slightly higher level fell into deep thought.

Those with a slightly lower level will be confused.

As for Professor Shu Yun, when Zhao Peiru said the first sentence, the corresponding steps were mapped out in his mind.

This 'piggyback liver transplant', she is too skilled!It was immediately clear that what Zhao Peiru was talking about was the last step between the "donor" and "recipient" before transfer.

"Is the anastomosis improved?"

"Make both the donor and the recipient into an inverted triangle anastomosis in advance?"

In Shu Yun's mind, a flash of inspiration suddenly appeared!

It was as if a flash of lightning suddenly appeared in the dark night sky!
Isn't this "unifying the caliber" in advance?

It's like connecting a faucet when a house is being renovated.

Generally speaking, each faucet joint is different in size and shape because "everyone is different".

When "butting" each water pipe and faucet, it has to be polished temporarily to figure out various ways to prevent "water leakage".

And this step of Zhao Peiru's operation is to trim the openings of the "faucet" and "water pipe" into a uniform shape and size in advance.

Unified the caliber in advance!
In this way, a lot of time can be saved when the liver is officially transplanted and the anastomosis is performed!

The reason is very simple.

But it is not so easy to apply this principle to the human body.

The human body is much more complex!
There are many such "docking ports" in the human body!The vena cava, hepatic artery, biliary tract, and jejunum all have dozens or hundreds of ports that need to be "docked"!Each requires a different "docking port".

In addition, what shape and size to build can make the "docking" work complete faster, and no one has mentioned it before.In other words, there is no docking step that needs to be started from scratch, and there are no reference materials.

This time, Zhao Peiru proposed the concept of "inverted triangle" for the first time in the history of medicine.

"Is this shape... more suitable for matching and docking?"

While thinking about it, Shu Yun subconsciously came to the "liver transplant simulation equipment" next to him.

"Xiao Zhang, turn on the equipment, and switch the surgery simulation process to the part before the donor-recipient transplant."

At the moment, the thoughts in her mind are very vague, and she can't grasp them!
I vaguely feel that the shape Zhao Peiru mentioned is very scientific!

But where the science is, and whether it really applies, she hasn't quite figured it out yet.

The others were even more confused. After seeing Professor Shu's actions, everyone gathered here quickly.

"This equipment is really advanced!"

On the big screen in front of everyone, a real "liver transplant operation" was displayed.

Shu Yundao: "In this device, 60 'piggyback liver transplant operations' I have performed are recorded, and this simulated reality is modeled based on my surgical operation data."

"In the past few years, we have relied on this equipment and continued to simulate trial and error to improve the 'piggyback' technology to the present level."

The envious eyes of everyone!
This advanced equipment is so useful!

You can continue to trial and error, continue to simulate, and modify many unreasonable details into mature details through this device!
If you can have one in your own hospital... just thinking about it makes your mouth water!
The deputy director of Jiren Hospital was a little proud when he saw that everyone was envious, but when he saw Zhao Peiru...

Only Zhao Peiru remained calm.

"This Director Zhao is indeed famous for his calmness, and his reputation is well-deserved!"

In the heart of the deputy director, Zhao Peiru showed the demeanor of a famous doctor!

In fact, Zhao Peiru had no interest in this device.

It's useless to him!
In his mind, there are all kinds of ready-made and excellent techniques, and there is no need for this kind of equipment to simulate and improve.

It is equivalent to saying that others are still in the process of running a race, but he has already stood at the finish line.Naturally, Zhao Peiru was not interested in "equipment that can increase speed in a race".

In addition, this kind of simulation equipment has many disadvantages, such as simulation cannot 100% restore reality after all.In the process of computer deduction, there may also be a huge deviation in the final result due to insufficient parameter samples.

In addition, it is impossible to simulate in time, and a large number of data samples must be input in advance.This is far from his "golden preview card".

With the advancement of surgical simulation on equipment...

The advantages of the inverted triangle anastomosis are also gradually revealed.

"This inverted triangle anastomosis, why is it so suitable!"

"Extremely effective in expanding the hepatic vein outlet of the donor liver and ensuring the patency of the anastomotic stoma!"

"The most important thing is that this kind of inverted triangle mouth is easy to operate and can be completed in a very short time during the operation, and the effect can be guaranteed!"

It combines the advantages of simple operation, quick effect and long time effect.

On the monitor, wait for the "docking and matching" part of this step to be completely completed.

Professor Shu pulled up a list and compared the time data.

If it works well, how long does it take?
Wait for the comparison list to come out...

Professor Shu's eyes froze!Almost speechless.

"This step of yours only took 26 minutes!"

When she was doing this operation, the whole process of anastomosis and butt joint took 60-90 minutes!

Compared with her "synthetic butt joint" operation, it saves a lot of time!
Don't look at the time as if it's not too close.You should know that this period of time is the patient's "anhepatic period", that is to say, the patient is enduring the adverse effects of "no normal compensation of liver function" at any time!Every minute and every second is extremely important!
Professor Shu Yun was completely shocked!

"Your inverted triangle anastomosis reduces the difficulty of vena cava separation and anastomosis..."

"The most important thing is that because of the short time, it can greatly reduce the severe pathological reaction in the anhepatic phase! It reduces the incidence of non-functioning liver transplantation or delayed recovery of liver function!"

Professor Shu Yun's eyes lit up.

This step of improvement is really meaningful!
In the whole operation, the most time-saving step is this step!I didn't expect that Zhao Peiru's improvement was exactly this!
She was so surprised!

Others also stared at the simulation result in astonishment.

One by one, there was a bang in my head!

If such an excellent effect can be achieved in the example operation, then the impact will be too great!

It can directly upgrade the "piggyback" to a higher level, making it more popular in the industry!

And Zhao Peiru, the improver, will definitely become famous!
