Chapter 18: Acquired Two Advanced Medical Skills
Each person received a live white mouse.
"The operation will take two hours. Let's begin."
Following the examiner's order, fifty candidates immediately began to anesthetize the white rat.
Then fix it to the wax plate.
Prepare all the instruments needed for the operation, arrange them according to personal usage, and start performing thoracotomy on the white mouse.
After Zhou Can fixed the white mouse, he held the lancet, selected the appropriate position, and slowly cut open.
All surgical steps need to be completed alone, without an assistant.
This undoubtedly increases the difficulty of the operation.
The third-level incision was very comfortable, perfectly avoiding the large blood vessels. The cutting depth of the knife was just right, without damaging any organs.
"Wow, why is the bleeding so severe?"
Zhou Can almost thought that he had cut an artery, and saw blood spurting out.
It gave him a big scare.
Rapid electrocoagulation to stop bleeding.
One bleeding point, two, three...
It took less than eleven seconds, and he stopped all the thirteen bleeding points.
The efficiency of the third-level hemostasis is amazing.
Every detail is accurate.
Of course, there are many ways to stop bleeding, such as clamping the blood vessels with hemostatic forceps, or ligating and anastomosing the broken blood vessels.
The blood vessels of mice are very small.
Since electrocoagulation can be used to stop bleeding, Zhou Can would naturally not go to such trouble to show off his medical skills.
"The bleeding is so severe, it's probably another trap set by the examiner."
Zhou Can raised his head and looked at the examiner, and sure enough, there was a sly smile on his face.
Pit B.
He cursed inwardly and turned to check on the other 49 candidates.
Many candidates were operating in a frenzy.
Someone's face was splattered with blood, but he didn't even bother to wipe it off.
It seemed that something had been done to each of the mice, causing them to bleed ten times faster than normal.
If the hemostasis technique is not good enough, the mouse may die from excessive blood loss right after the chest is opened.
Zhou Can felt relieved.
Fortunately, my hemostasis skills have been improved to the mid-level level for residents.
This is the only way to deal with it calmly.
After opening the chest cavity, the liver, lungs, heart and other internal organs were all exposed in his surgical field of view.
First find the large blood vessels at the root of the left lung and ligate them at the proximal end.
This is to prevent massive bleeding when the left lung is removed.
Then carefully separate the left lung from the surrounding tissues bit by bit.
[Congratulations on obtaining the separation skill. Current experience value: Level 3, 0.2/1000. It can be used to separate adhesions between tissues in the body.]
Dissection is an advanced medical technique based on anatomy.
Its application scenarios are very wide.
For example, when removing a tumor, the tumor is separated from normal body tissue. Or when performing surgery on some special parts of the body, a body organ needs to be moved away first, which also requires separation.
Separating necrotic tissue from the patient requires separation surgery.
The sudden addition of an advanced medical skill made Zhou Can feel both pleasantly surprised and unexpected.
"As soon as I got it, it was level three?"
Aren’t other medical skills all at level one when they first start?
After a little thought, Zhou Can understood what was going on.
Dissection is derived from incision.
His incision is currently level three, so the separation will be level three as soon as it comes out.
Each time you practice medical skills on a living prop, you gain 0.2 experience points.
So the current experience value is level three, 0.2/1000.
Finally figured it out.
Now that the left lung had been successfully separated from the surrounding tissue, he decisively removed it.
Fortunately, the main blood vessels were ligated in advance.
Otherwise, with the amount of blood in the white mouse, it would probably spray out all the blood in its body in less than ten seconds.
It's much simpler now.
Just perform electrocoagulation to stop bleeding on those small blood vessels.
The total amount of bleeding was very small.
The wound is then cleaned, and after checking that everything is correct, the subcutaneous tissue is sutured and the chest cavity is closed.
The entire left lung resection operation was completed neatly and efficiently.
After closing the chest cavity, he began the second operation.
First, use elastic thread to tighten the base of the tail, then cut off the tail, and then start vascular anastomosis with the help of a microscope.
There are four major vessels that require anastomosis.
This is an extremely delicate project.
The sewing needle is thinner than a hair.
The operation is extremely difficult.
Even though his suturing and ligation skills were all level three, it still took him a lot of effort to finally anastomose the first blood vessel.
[Congratulations on obtaining the anastomosis technique. Current experience value: Level 3, 0.2/1000. It can be used to anastomose blood vessels, nerves, intestines and other organs.]
Wow, there are surprises one after another.
He also acquired an advanced medical skill .
And it’s also level three.
Anastomosis is derived from incision and suturing and is used very frequently in surgical operations.
Zhou Can vaguely realized that as long as he mastered the four basic medical skills of incision, suturing, ligation and hemostasis, the advanced medical skills he would acquire in the future would be directly on the same level as the corresponding basic medical skills.
The basic medical skills are level five, and the advanced medical skills acquired will also be level five.
This is very good.
It is equivalent to a shortcut that allows him to grow faster.
There are four main blood vessels in the rat's tail. He carefully sutured the remaining three blood vessels one by one.
Checked and found nothing wrong.
After untying the elastic cord tied at the base of the rat's tail and passing blood, none of the anastomosed blood vessels leaked or were blocked.
The end near the rat's tail regained its color after blood supply was restored.
Not bad, all four blood vessels are unobstructed.
Zhou Can let out a long sigh.
In theory, the operation can be successfully completed at this stage.
He looked at the time and it took less than an hour. If he handed in the paper now, he would probably just sit there and wait. So in order not to waste time, he decided to try a rat coccygeal nerve anastomosis.
Because nerves are much thinner than blood vessels, and nerves are composed of countless nerve filaments.
This anastomosis is more than ten times more difficult than vascular anastomosis.
A complete nerve bundle is equivalent to a tube, with hundreds or thousands of thin nerve filaments inserted inside.
Nerve signals are transmitted through neurofilaments.
When this nerve is severed, in order to fully restore its function, it is necessary to ensure that each nanometer-thin nerve filament is aligned with the original one.
You can imagine how difficult this is.
Zhou Can is naturally not at that level now.
As long as the severed nerves can be roughly reconnected, it would be very good.
As to how much neurological function can be restored, no one can say for sure.
All he can do now is to make a more precise match.
Under the microscope, he performed nerve anastomosis with difficulty.
Trying to reconnect the severed nerves .
Nerve cell death is irreversible; neurons are permanent cells.
The nerves after anastomosis
Zhou Can sutured the severed nerves and then sutured the muscles and cortex at the severed tail.
The mouse's tail was covered with rows of tiny scales under its epidermis, which made the suturing more difficult to a certain extent. But it was not a problem for him.
After the stitching was completed, he checked it carefully.
The mouse's heartbeat was stable, the wound was sutured smoothly, and it was ready to be handed in.
Zhou Can looked at the time and it took a total of 80 minutes.
The speed of this operation can definitely be described as lightning fast.
Normally, for some people with poor suturing skills, 80 minutes would probably be enough to only suturing the blood vessels of a rat’s tail.
"Examiner, I'm done."
Zhou Can raised his hand and handed in the paper.
The examiner took a look and was surprised to see that this boy was the first to hand in his paper.
