Each person received a live white mouse.
"Surgery time is two hours, begin now."
With the examiners' command, all fifty examinees immediately began to anesthetize the white mice.
Then they fixed them onto the wax plates.
They prepared all the surgical instruments needed, arranged them according to personal habits, and began the chest-opening surgery on the white mice.
After Zhou Can secured the white mouse, he held a scalpel, selected an appropriate incision site, and slowly cut open.
All surgical steps had to be completed alone, without any assistants.
This undoubtedly increased the difficulty of the surgery.
Level 3 Incision Skill is great; it perfectly avoided major blood vessels. The depth of the cut with the knife was just right, not damaging any organs.
"Wow, how can the bleeding be so severe?"
Zhou Can nearly thought he had cut the arterial blood vessels, seeing blood spritzing out profusely.
It gave him quite a scare.
He rapidly cauterized to stop the bleeding.
One bleeding point, two, three...
In less than eleven seconds, he stopped all thirteen bleeding points.
The efficiency of Level 3 Hemostasis Skill was exhilarating.
Accurate with every point.
Of course, there are many methods of stopping bleeding, such as clamping the vessel with a hemostatic forceps, or performing ligation or anastomosis on severed vessels – all are possible.
The white mouse's blood vessels are very small.
If electric cauterization can stop the bleeding, Zhou Can would naturally not bring trouble upon himself just to show off medical techniques.
"Such furious bleeding, mostly another pitfall set by the examiners."
Zhou Can looked up at the examiners and, as expected, saw a sly smile on their faces.
Pitfall B.
He cursed silently and turned to check the situation of the other 49 examinees.
Many examinees were operating in a flustered manner.
Some of them got blood splashed on their faces, unable to even bother wiping it off.
It seems that every white mouse had been tampered with; the speed of bleeding was ten times normal.
If one's Hemostasis Skill was a little weak, it's very possible that the mouse would die from excessive blood loss shortly after the chest was opened.
Zhou Can felt relieved.
Luckily, the Hemostasis Skill had been elevated to a mid-level Resident Doctor's standard.
This allowed him to handle the situation calmly.
After opening the chest cavity, organs such as the liver, lungs, and heart were all exposed to his surgical view.
First, located the major blood vessel at the root of the left lung and tied it near the proximal heart end.
This was to prevent massive bleeding when removing the left lung.
Then he carefully separated the left lung from the surrounding tissues, little by little.
[Congratulations, you have obtained the Separation Skill, current Experience Points, Level 3, 0.2/1000. Can be used to separate adhesions between various body tissues.]
The Separation Skill is an Advanced Medical Skill established on the basis of anatomy.
Its application scenarios are broad.
For instance, when removing tumors, separating the tumor from normal body tissues. Or in surgeries at some special sites, it's necessary to move certain body organs aside, which also requires the Separation Skill.
Separating necrotic tissue from a patient is also inseparable from the Separation Skill.
The sudden acquisition of an Advanced Medical Skill caused Zhou Can both surprise and astonishment.
"Just obtained and it's Level 3?"
Aren't other medical skills starting from Level 1?
After a bit of contemplation, Zhou Can figured out what was going on.
The Separation Skill was derived from the Incision Skill.
His Incision Skill is currently Level 3, hence the Separation Skill came out immediately at Level 3.
Practice a medical skill once on a live prop to increase Experience Points by 0.2.
That's why the current Experience Points are Level 3, 0.2/1000.
He finally understood.
Now that the left lung was successfully separated from the surrounding tissues, he decisively removed it.
Fortunately, he had pre-tied the main vessels.
Otherwise, with the small amount of blood in the white mouse, it probably wouldn't take ten seconds to completely drain its blood.
At this moment, it became much simpler.
All that needed to be done was to cauterize those small blood vessels for hemostasis.
The total blood loss was minimal.
Then, after cleaning the wound and ensuring there were no errors, the subcutaneous tissue was sutured, and the thoracic cavity closed.
The entire left lung resection surgery was completed smoothly and decisively.
After closing the thoracic cavity, he began the second surgery.
First, he used an elastic band to tightly wrap around the base of the tail, then cut off the rat's tail, and with the help of a microscope, he began vascular anastomosis.
There were four main blood vessels to be anastomosed.
This was an extremely delicate process.
The sutures were thinner than hair strands.
The difficulty of the operation was extremely high.
Even though Zhou Can's Suturing Skill and Ligation Skill were both Level 3, it still took a great deal of effort to finally complete the anastomosis of the first blood vessel.
[Congratulations, you have acquired the Anastomosis skill, current Experience Points, Level 3, 0.2/1000. It can be used to anastomose blood vessels, nerves, intestines, and other organs.]
What a nice surprise, one after another!
He had acquired another Advanced Medical Skill.
And it was also Level 3.
Anastomosis is derived from Incision and Suturing. It is used very frequently in surgical operations.
Zhou Can vaguely realized that as long as he practiced the four basic medical skills of incision, suturing, ligation, and hemostasis well, the advanced medical skills acquired in the future would directly match the level of the corresponding basic skills.
If the basic medical skill is Level 5, then the acquired Advanced Medical Skill would also be Level 5.
This was quite good.
It was akin to a shortcut that would allow him to grow faster.
There were a total of four main blood vessels in the rat's tail, and he carefully anastomosed the remaining three vessels one by one.
Upon examination, there were no errors.
Releasing the elastic band wrapped around the base of the tail, and after the resumption of blood flow, the anastomosed blood vessels exhibited no leak or obstruction.
At the end closer to the tail, the re-supply of blood brought back its color.
Not bad, all four blood vessels were fully patent.
Zhou Can let out a long breath of relief.
Normally, the surgery would be considered successfully completed at this point.
He looked at the time; it had been less than 1 hour in total. Submitting now would probably mean just sitting around waiting foolishly. Therefore, adhering to the principle of not wasting time, he decided to attempt a rat tail nerve anastomosis.
Because nerves are much finer than blood vessels, and a nerve consists of countless nerve fibers.
The difficulty of this anastomosis was more than tenfold higher than that of vascular anastomosis.
A complete nerve bundle is like a tube, with hundreds to thousands of fine nerve fibers inside.
The nerve signals are transmitted through these nerve fibers.
When this nerve is severed, in order to fully restore its function, it must ensure that each of the nanometer-sized fine nerve fibers is aligned with its original position.
As one can imagine, the difficulty is immense.
Zhou Can naturally didn't have that level of skill yet.
If he could perform a general anastomosis of the severed nerve, that would already be quite impressive.
As for how much nerve function could be restored, no one could say for certain.
All he could do now was to perform a more accurate anastomosis.
Under the microscope, he painstakingly performed the nerve anastomosis.
He strove to reconnect the severed nerve.
Nerve cells are non-regenerable upon death; neuronal cells are permanent cells.
The fact that an anastomosed nerve can regain some function is due to the fact that the normal cells in the necrotic region produce many synapses. These synapses contact each other and serve to compensate well for the function of the necrotic region.
Zhou Can completed the anastomosis of the severed nerve, then proceeded to suture the muscles and skin at the stump of the tail.
The underside of the rat's tail was covered with rows of tiny scales, which added a certain degree of difficulty to the suturing process. However, it didn't stump him.
After suturing, he carefully checked everything over.
The rat's heartbeat was stable, the sutured wound was smooth, and it was time to submit his work.
Zhou Can checked the time; the total procedure took 80 minutes.
The speed of the surgery was definitely remarkable.
Ordinarily, for someone with lower suturing skills, 80 minutes would probably only be enough to anastomose the blood vessels of the rat tail.
"Examiner, I've finished."
Zhou Can raised his hand to submit his work.
The examiner looked over and thought, oh, it's this young man finishing first again.
