Each received a live mouse.

"The surgery lasts two hours, let's get started."

With the examiner's order, fifty candidates immediately began to anesthetize the mice.

It is then fixed to a wax dish.

Prepare all the instruments needed for the operation, arrange them according to personal habits, and start the thoracotomy on the mice.

After Zhou Can fixed the white mouse, he held the lancet, selected a suitable knife position, and cut it slowly.

All the surgical procedures need to be done by yourself, without an assistant.

This undoubtedly makes the surgery more difficult.

The tertiary incision is cool, and it perfectly avoids the large blood vessels. The depth of the knife is also just right, and it does not hurt any organs.

"Wow, how can the bleeding be so bad?"

Zhou Can almost thought that he had cut off the large arteries, only to see blood spurting out.

Took him by surprise.

Rapid electrocoagulation to stop bleeding.

One bleed spot, two, three ......

It took less than eleven seconds for him to stop all thirteen bleeding points.

The efficiency of the tertiary hemostasis is refreshing.

A little bit at a time.

Of course, there are many ways to stop bleeding, such as clamping the blood vessel with a hemostat, or ligating and anastomosizing the broken blood vessel.

White rats have very small blood vessels.

can electrocoagulate and stop bleeding, Zhou Can naturally will not bother himself in order to show off his medical skills.

"The bleeding is so fierce, most of it is a pit dug by the examiner."

Zhou Can looked up at the examiner, and sure enough, there was a wicked smile on the corner of his mouth.

Pit B.

He cursed and turned his head to check on the other 49 candidates.

A number of candidates are scrambling to operate.

Someone's face was splattered with blood, and he didn't bother to wipe it.

It appears that each rat has been hand-to-footed, bleeding ten times faster than normal bleeding.

If the hemostasis is a little bit, it is likely that the white rat will die of excessive blood loss just after the chest is opened.

Zhou Can was glad for a while.

Fortunately, hemostasis has been upgraded to the average level of a resident doctor.

That's how you can deal with it.

After opening the chest cavity, the liver, lungs, heart and other internal organs were all exposed to his surgical vision.

The large blood vessels at the root of the left lung were first identified and ligated at the proximal end.

This is to prevent heavy bleeding when the left lung is removed.

Then the left lung is carefully separated from the surrounding tissues little by little.

[Congratulations on obtaining the Separation Technique, current experience points, level 3, 0.2/1000.] It can be used to separate adhesions between tissues in the body. 】

Dissociation is a higher medical technique based on anatomy.

It has a wide range of application scenarios.

For example, when a tumor is removed, the tumor is removed from normal body tissue. Or in some special parts of the operation, it is necessary to remove a certain body organ first, and it is also necessary to use dissociation.

The separation of necrotic tissue from the patient is even more inseparable from dissection.

The sudden addition of a higher medical skill surprised and surprised Zhou Can.

"As soon as you get it, it's level three?"

When other medical techniques first started, weren't they all level 1?

After a little pondering, Zhou Can understood what was going on.

Dissociation is derived from incision.

His incision is currently level three, so the dissection is level three as soon as it comes out.

Each time you practice healing on a living item, you gain 0.2 experience.

So the current XP is level 3, 0.2/1000.

Finally figured it out.

Now that the left lung has been successfully separated from the surrounding tissue, he decisively removed it.

Fortunately, the main blood vessels were ligated ahead of schedule.

Otherwise, with the amount of blood of the white mouse, it is estimated that it will take less than ten seconds to squirt the blood in the body.

It's a lot simpler now.

Electrocoagulation is all that is needed to stop bleeding with those small blood vessels.

The bleeding throughout is very minimal.

The wound is then cleaned and the subcutaneous tissue is sutured to close the ribcage.

A complete set of left lung resection surgeries was done neatly.

After closing the ribcage, he began to have a second operation.

The root of the tail is tightened with elastic wire, and then the rat tail is truncated, and then the vascular anastomosis is performed with the help of a microscope.

There are four major blood vessels that need to be anastomized.

It's an extremely delicate piece of engineering.

The stitches are thinner than a hair.

It is extremely difficult to operate.

Rao is that his sutures and ligations are all level three, and it still took a lot of effort to finally anastomoses the first blood vessel.

[Congratulations on obtaining anastomosis, current experience points, level 3, 0.2/1000.] It can be used to anastomosis blood vessels, nerves, intestines and other organs. 】

Good guys, this surprise is one after another.

He also acquired a higher medical skill.

And it's also level three.

Anastomosis is derived from incision and suture. It is used extremely frequently in surgical procedures.

Zhou Can faintly realized that as long as the four basic medical skills of incision, suture, ligation, and hemostasis were practiced, the advanced medical skills obtained in the future would be directly at the same level as the corresponding basic medical skills.

The basic medical skill is level 5, and the advanced medical skill obtained will also be level 5.

That's pretty good.

It's like a shortcut that allows him to grow faster.

There are four major blood vessels in the tail of the white rat, and he carefully fits the remaining three blood vessels one by one.

Check that it is correct.

Untie the elastic line tied to the root of the rat's tail, and after passing the blood, none of the anastomosed blood vessels leak or block.

At the end of the rat's tail, when the blood supply was restored, the blood color was restored.

Not bad, all four blood vessels are unblocked.

Zhou Can breathed a long sigh of relief.

It stands to reason that the operation can be successfully completed at this point.

He looked at the time, and it took less than 1 hour in total. Now that I am handing in the papers, I guess I am also sitting and waiting stupidly. So in line with the principle of not wasting time, it was decided to try a rattail nerve anastomosis.

Since nerves are much thinner than blood vessels, and nerves are made up of countless nerve filaments.

This anastomosis is more than 10 times more difficult than vascular anastomosis.

A complete bundle of nerves is equivalent to a tube, and then hundreds or thousands of thin nerve filaments are inserted into it.

Nerve signals are transmitted through nerve filaments.

When this nerve is severed, in order for it to fully function, it is necessary to ensure that each nerve filament, down to the nanometer level, is aligned with the original.

You can imagine how difficult this is.

Zhou Can naturally doesn't have that level now.

As long as the severed nerve can roughly fit well, it is already very good.

As for how much nerve function can be restored, no one can say.

What he can do now is a more precise match.

Under the microscope, he struggled to do a nerve anastomosis.

Try to get the broken nerve back together.

Nerve cell death is non-renewable, and neuronal cells are permanent cells.

The neurological recovery of part of the function after anastomosis is due to the fact that the normal cells in the necrotic site will produce many synapses, and these synapses are in contact with each other, which has a better effect on the functional compensation of the necrotic site.

Zhou Can anastomosed the severed nerve, and then sutured the muscles and cortex at the severed tail.

The tail of the mouse is covered with small scales under the epidermis of the tail, which makes it difficult to suture to some extent. But it didn't bother him.

After the stitches were finished, he double-checked them.

The rat's heartbeat is stable, the wound is sutured flat, and it is ready to be rolled.

Zhou Can looked at the time, and it took a total of 80 minutes.

The speed of the operation is absolutely superb.

Normally, some people who suture horizontal dishes are estimated to be only enough to anastomosis the blood vessels of the rat's tail in 80 minutes.

"Examiner, I'm done."

Zhou Can raised his hand and handed over the paper.

The examiner looked, yo, it was this kid who was the first to hand in the paper.
