Big Doctor Live Room

Chapter 195
Chapter 195 I lost a hundred million
Unexpectedly, this Viking would also transform into a literary youth.

Chen Qun murmured silently in his heart, knowing that today's demonstration operation may only be a demonstration, not an operation.At least now in the operating room, it doesn't look like an operation is going to be performed.

No wonder the number of professors who came to attend lectures today is much less than the first two times.After all, at this stage, surgery is still the main content of surgical medicine, and minimally invasive surgery is still a supplementary part.Even if this kind of laser positioning surgery is a cutting-edge science, for most professors, it's just a matter of seeing it, and it doesn't improve their own surgical ability much.

Without demand, there is naturally no motivation.Chen Qun suddenly understood that most of the classrooms today were young doctors. Of course, it could not be ruled out that the hospital deliberately arranged for the younger generation to learn this technique, and the older generation would not have to compete for a seat here.

Professor Thomson's voice in the dark resounded through the entire auditorium as more colorful lines spread.

"Every stroke a painter draws, every note a musician draws, every symbol a mathematician writes, and every choice a student makes will trigger neurons to generate neurotransmission. Numerous neuron transmissions, combined in the brain, shape Different selves emerged one by one, which created the reason why we are human, and led to the emergence of thinking."

While speaking, countless colorful lines intertwined and entangled on the screen, like countless spider webs, densely filling the entire picture.The picture changes from large to small, and the lens gradually becomes farther away. The intertwined spider webs in front gradually take on the shape of a brain.Several different brain regions, also appearing in different colors.

"This is the three-dimensional picture of the connection and activity of brain neurons presented through modern technology, and it is also the basic principle of the stereotaxic laser ablation technology we are going to teach today. Perhaps some students have already realized that the technology used in this technology Stereotaxic is actually achieved by using our nuclear magnetic resonance technology."

While speaking, the lights in the lecture theater turned on, shining on the red-bearded professor in a white coat, like a wise man from the long river of history, and like an angel walking out of the Garden of Eden.

"Of course, this is slightly different from MRI, that is, we use newer algorithms and more professional imaging techniques to locate the target. Then we use the hot laser probe to display the image of neuron connections on the screen. , locate and target the deformed lesion, and then use laser to ablate and complete the operation.”

"It's just that this surgery is slightly different from other interventional surgeries. The trajectory of the laser must be precise, and there is no chance of repeating it. If there are only one or two tiny thrombus or the pathological deviation of the lesion, the surgery may be terminated immediately. The damage wasn't that great."

"But if you encounter some important nerve centers or important blood vessels, as long as there is a mistake, it will lead to more serious bleeding, epilepsy or brain death. Moreover, the structure of the brain is very similar to the blood, that is, the substances inside will There is a slight gap between the flow, its position and the place shown in the MRI. Sometimes, in order to ensure the smooth progress of the operation, we need to use imaging technology to target and locate the lesion.”

"But even if there are positioning images, there will be some errors. This requires rich experience in surgical neurosurgery to eliminate interference and perform surgery. This is also a problem that has arisen during the promotion of this technology, and there is no suitable one until now. The solution. Perhaps, the ancient oriental meridian theory can find a better revision plan for this technique."

When Chen Qun heard the last two sentences, he immediately gave a high evaluation to this red-bearded professor who was more like a pirate than a surgeon.

This Professor Thomson should be a pure scholar and medical scientist, so he can rationally evaluate the theory of Chinese medicine in China.But I'm afraid he will be disappointed. Even if there is a meridian theory, I'm afraid it can't solve the problem of material flow in the brain. More advanced technology is needed for precise positioning.

The other two shadowless lights lit up on the operating table, and a model that looked like a human brain appeared on the operating table.

Professor Thomson bowed slightly, explaining the reason regrettably.

"Originally, there was a demonstration patient, but it is a pity that the patient suddenly burst a cerebral blood vessel one day ago, and the rescue failed and died. There is no patient for the scheduled demonstration operation, so I have to temporarily demonstrate it with props. However, I We found a patient, but her brain lesion has not been fully described, and we still need a few days before we can formally perform a difficult operation for you here. At the same time, this operation will have this The inventor of the technology, my colleagues show it to you."

Hearing these words, Chen Qun understood Qi Hong's entanglement more and more.But even if Professor Thomson wanted to develop this new technology, he would do his best to provide Feng Qiuyun with the best surgery.This is also the only way for the development of modern medicine. Any operation is accumulated with human life.The only difference is the number of people.

"Insert the laser probe into the cooling duct for positioning and locking!"

Following the orders of the red-bearded pirate, the two assistants inserted a laser probe with the thickness of a hairspring in the interventional operation into a platform with a glass catheter [-] to [-] centimeters long.One end of the probe bent several arcs in the air, aiming at a fluorescent part of the brain model.

Almost at the same time, several large and small screens in the auditorium displayed the three-dimensional data of the positioning, as well as the frequency and power of the laser and the temperature of the cooling tube.

Chen Qun saw that the temperature on the laser tube was not high, and with a flash of green laser light penetrating into the cooling tube, the temperature suddenly became thirteen degrees Celsius acceptable to ordinary people.The green light spot irradiated the marked fluorescent position at once.

I saw that as the lens zoomed in, traces of almost invisible smoke and dust appeared on the fluorescent light, and disappeared before flying up, and the fluorescent light disappeared together.

Hey, foreigners are really not authentic. What he wants to know most is how to reduce the damage to the brain structure and nerves by the laser emitted by the probe?Whether it is to use a probe to penetrate deep into the cerebral cortex, or to use a laser to strike directly at a long distance, it will make a mess of the brain, especially in the face of some brain tumor lesions hidden deep under the cerebral cortex.

Chen Qun felt that there was absolutely no need for him to come and study this class.Two of his patient simulators were riddled with holes by him with lasers and died.This foreign professor must have some skills, but he hid them at this time.

He felt that he had lost a hundred million!

Chen Qun made a decisive decision, deliberately picked up the phone and took a look, then sneaked out of the lecture theater and rushed to the plastic surgery clinic as fast as possible.He has at least a dozen patients waiting for his operation.
