A spare one.
Because when the battery runs out, the patient’s artificial heart will stop beating.
This limitation is too significant.
Currently, abroad, the best site for developing an artificial heart is considered the human thigh.
Extract the femoral artery and a large vein, using a series of techniques to induce fusion, proliferation, and changes.
However, this experiment violates several legal provisions regarding human rights, making it impossible to conduct on human bodies.
Perhaps there are instances, but only conducted secretly in laboratories.
Just like the once-popular cloning technology.
If this technology were applied medically, it would also address the issue of organ transplant shortages.
It’s also banned for the same legal violations.
Mankind has reached a stage today where many new technologies warrant deep exploration.
Li Jingsheng seriously pondered the reason for the proliferation of these three small blood vessels.
Could it be that neurological disorders triggered vascular proliferation?
Considering the patient’s left upper limb has a nine-centimeter segment of the radial nerve swollen, accompanied by nerve constriction, and even nearly complete rupture in one place, he concluded it must be a neurological disorder.
Not caused by vascular disease.
"It’s necessary to conduct a pathological examination on the patient!"
This time, without hesitation, having reached this point, he wanted to see what caused such severe nerve disorders in the patient.
The results came quickly.
Pathological examination revealed inflammatory cell infiltration dominated by lymphocytes into the nerves, along with vascular lumen narrowing and partial closure.
Nerve swelling accompanied by axonal thinning and a significant reduction in number.
Li Jingsheng understood why those three small blood vessels proliferated after reviewing the pathological results.
Because the vessels have a substitution mechanism.
It’s also a survival mechanism.
For instance, in some patients, when the heart’s major blood vessels become obstructed or narrowed, heart blood supply becomes an issue.
The body makes adjustments, and some small vessels connected to this major vessel slowly thicken, replacing much of the blood-supply function of this major vessel.
These patients may experience palpitations, shortness of breath, fatigue, etc.
When examined at the hospital, it may be revealed that ancestors’ blessings caused the major artery to become completely blocked. Normally, they would have had a heart attack or sudden death, but the surrounding vessels of this aorta saved their lives.
Although they struggled to thicken, they still couldn’t meet the aorta’s blood supply requirements.
But they can replace 60-70% of the aorta’s blood supply capability.
Thus, the patient only feels weak, with palpitations and shortness of breath, but won’t have cardiac arrest.
This patient’s radial nerve was damaged by inflammatory cells dominated by lymphocytes, causing surrounding vascular lumen to narrow and partially close, forcing those three small vessels to proliferate, bridging the diseased radial nerve for blood supply.
At this point, the cause is basically clear.
But a more detailed cause can’t be further investigated.
At least he lacked the conditions to continue probing.
Perhaps when future scientists conduct more in-depth research, they can discover why inflammatory cells dominated by lymphocytes damage nerves.
Just like the initial malignant tumors, these also fall under unknown diseases.
Li Jingsheng also classified this illness as an unknown disease.
His diagnosis noted that the left radial nerve showed hourglass-like lesions, suggesting surgical treatment.
Then he provided a surgical plan.
Submit the answer.
"Damn it, lost two points."
Zhong Hu slapped his thigh with an extremely frustrated expression.
"What the hell, Xiaoli, how are you three points higher than me?"
Zhong Hu saw on the big screen that his group jumped from over twenty rankings to fourth place. Tied first with the top three.
This team strategy’s advantage is as long as one person answers correctly, it counts.
Zhong Hu lost two points, either due to a missed diagnosis or an unnecessary excess examination.
In terms of Li Jingsheng scoring one point above the perfect score, it was an extra point.
