From small clinic to medical empire

Chapter 234: How Many Cuts Are There?

and so……

In addition to sending students to participate in the basic research of neuron induction, should a few students with good clinical skills be sent to Haoran Hospital for further study?
This thought surprised Wang Bin himself.

Yanshan Hospital is directly under the Ministry of Health, and it's not that the doctors in the hospital have never been sent to other hospitals for further study.

But the object of going is either traveling in Europe or visiting the United States, and even the hospitals in Japan are looked down upon, let alone domestic hospitals.

Send the main doctor to a private hospital in the south for further training...

If you say this kind of thing, I'm afraid you will be sprayed to death immediately!
Wang Bin smiled bitterly and shook his head, feeling that he was really whimsical.

Although the Dean Zhang in front of him has never stopped in his hand, and he has found the location very accurately, but who knows if his repair will have any effect?
Maybe it's just playing tricks?

This was Zhang Zifan's second incomprehensible behavior for Wang Bin.

Because the texture of brain tissue is very similar to tofu, blunt dissection should only be used as a secondary method.

Therefore, external brain surgery is generally performed, and the surgical instrument is a very unique bipolar electric knife.

The so-called bipolar electric knife is a kind of Z-shaped gun-like tweezers.

The whole operation is mainly completed through a series of actions of bipolar cauterization-sharp dissection with micro-scissors and blunt dissection with aspirator.

Wang Bin introduced how to use the double-click electric knife early in the morning, and said that he can cooperate with Zhang Zifan in the operation.

Of course, Wang Bin's so-called "surgery" is to find a random necrotic focus and burn it after the craniotomy, and then call it a day, instead of doing a big project like Zhang Zifan.

But the problem is that Zhang Zifan has no intention of using the bipolar electric knife at all. According to him, the damage of the bipolar electric knife is too great to be suitable for today's surgery.

From the beginning to the end, Zhang Zifan used Shi Xiaoya to provide the surgical instruments.

In addition to common brain surgery instruments such as micro scissors and brain pressure plate, there is only a special bur and a low-power electrocoagulation knife.

Well, from Wang Bin's point of view, Zhang Zifan's electrocoagulation knife is indeed very powerful, but the electrocoagulation effect looks very good, no wonder it has to be brought all the way to Europe.

……

If Zhang Zifan knew what Wang Bin was thinking, he would definitely be able to shake his head. The electrocoagulation knife in his hand is not actually low in power, but just in low smoke.

This [Minimally Invasive Electrosurgical Knife] was a system item that Zhang Zifan got when he had an operation in the United States almost a year ago.

In addition to the relatively small trauma, the biggest advantage of this electric knife is that the smoke and barbecue smell produced are reduced by 50%.

Goodness, the smell of grilled meat, especially burning fat, is already unbearable, let alone brain-burning.

The brain is basically full of fat!
Zhang Zifan was not ready yet, so he kept his sense of smell thanks to this [minimally invasive electrosurgery].

On the other hand, Zhang Zifan did have his own reasons for not choosing a bipolar electric knife.

The first is what Zhang Zifan said before, if electrocautery is used, the damage to the tissue is indeed relatively large.

The second is that after Zhang Zifan's head and neck surgery skills reached S-level, he acquired a new special skill [vascular flow restriction].

The advantage of the bipolar electric knife is that it also has the function of electrocoagulation while cutting, which can stop bleeding at any time and reduce intraoperative bleeding.

With the skill of [Vascular Flow Restriction], Zhang Zifan can control the flow rate of local blood supply to minimize bleeding during minimally invasive surgery.

However, [vascular flow restriction] does not limit the flow indefinitely.

The brain is an organ highly dependent on blood oxygen supply.

The human brain only accounts for about 2% of body weight, but consumes more than 25% of its oxygen.

If it is when studying for an exam, the brain will be further congested, and the oxygen consumption can soar to more than [-]%.

Therefore, if the blood supply to the brain tissue is cut off for a long time, it will cause irreversible necrosis of the brain tissue.

Therefore, Zhang Zifan must complete the operation in one area within 2-3 minutes, and then use [universal glue] to stop the damaged blood vessels.

When the wound is too large and it is a last resort, Zhang Zifan will use [Minimally Invasive Electrosurgical Knife] electrocoagulation to stop the bleeding.

Even so [Minimally Invasive Electrosurgical] is much less damaging than bipolar electrosurgical.

……

While Wang Bin was fighting with heaven and man, Zhang Zifan had already completed the repair of the damage on the surface of the brain.

In Zhang Zifan's field of vision, all the yellow icons turned into light green or light yellow.

It will take time and supportive treatment for them to transform into the dark green color that represents complete health.

However, there is still a big red icon, still in the center of the field of vision, very eye-catching.

Zhang Zifan looked at the CT images on the wall-mounted monitor beside him.

On CT images, this area is not obvious.

It can even be said that there is no difference between the density and structure of the image and normal brain tissue.

So far, it has not been diagnosed or treated by any brain surgeon.

And its location is not on the surface of the brain, but in the deep part of the brain fissure.

The brain is not flat. The so-called fissure is the deep gully between the lateral fissure, columns, tentorium, and gyri.

For superficial lesions of the brain, surgery can be performed through the natural channel of the fissure.

Although it is said that the brain is like tofu, it cannot be touched, but even tofu has a certain degree of elasticity, can withstand slight stretching, and the exposed space is enough for surgery.

But once the damaged part is too deep, simple pulling can no longer solve the problem.

Pulling forcibly would be very dangerous.

The solution is simple to say the least.

That's what surgeons do most often: cut!

Never cut off when trouble arises is the golden rule of surgeons, probably inherited from the European "veterinarians" in the barbaric era.

It's brutal, but it works.

Making an incision along the sulcus between the brain gyri is called a sulciostomy in academic language.

A fistula is a tube, and a ostomy is the artificial creation of a tube leading to the inside of the brain.

Obviously, in order to avoid increased trauma, the shortest and safest path for fistula must be chosen to protect the brain tissue to the greatest extent.

According to the CT images, the projection of the lesion under the shortest path is drawn on the patient's body surface, and surgical incision is made to enter.

This is the housekeeping skill of a brain surgery doctor.

Young doctors need to use computer-aided measurements for a long time, and the big guys are almost inseparable by direct visual inspection.

But the problem is, these things are all done before surgery.

But now, Zhang Zifan discovered the large red lesion during the operation after incision of the skull.

How exactly should the fistula be incised, Zhang Zifan hesitated.

Tried to use [Eye of Preset] for path analysis, but none of the self-created spells had a completion rate of more than 80%.

Sure enough, it is useless to speculate on your own without standing on the shoulders of those in front of you.

Zhang Zifan raised his head and asked Professor Wang Bin beside him who was thinking hard, "Comrade Wang, tell me, how many ways can you cut this brain circuit?"
