Chapter 195 loss of 100 million

I didn't expect that this Viking would change into a literary youth.

Chen Qun silently make complaints about the demonstration surgery today. I am afraid that I can only demonstrate and operate without demonstrating the demonstration operation today. At least now in the operating room, it doesn't look like an operation.

No wonder there are fewer professors here today than the first two. After all, at this stage, surgery is still the main content of surgery, 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, the most important thing is to have a look, which will not improve their own surgical ability.

Without demand, there is no motivation. Chen Qun understood that most of today's classrooms are due to young doctors. Of course, the hospital has deliberately arranged for the younger generation to learn this technology, while the older generation does not have to compete here.

In the dark, Professor Thomson's voice once again with the spread of more colorful lines, resounding throughout the classroom.

"Every stroke a painter draws, every note a musician plays, every symbol a mathematician writes, every choice a student makes will trigger neurons to produce neurotransmission. Innumerable neurons transmit and unite in the brain to create different selves, which makes us human and leads to the emergence of thinking. "

Speaking, countless colorful lines intertwined on the screen, such as numerous spider webs, densely filling the whole picture. And the picture changes from big to small, the lens gradually becomes far away, and the spider webs intertwined in front of it gradually take on the shape of a brain. Several different brain regions also show different colors.

"This is the three-dimensional picture of brain neurons interacting with each other through modern science and technology. It is also the basic principle of stereotactic laser ablation technology that we are going to teach today. Maybe some students have reflected that the stereo positioning used in this technology is actually achieved by using our NMR technology. "

As he spoke, the light of the classroom lit up and shone on the red bearded professor in a white coat, just like a wise man from the long river of history and an angel from the garden of Eden.

"Of course, this is slightly different from NMR, that is, we use newer algorithms and more professional development technology to locate the target. Then we use the thermal laser probe to locate and target the abnormal lesion on the neuron connection image displayed on the screen, and then use the laser to conduct ablation and complete the operation. "

"It's just that this procedure is a little different from other interventional procedures. That is, the laser trajectory must be accurate, and there is no chance to come back. If only one or two tiny thrombi or diseased parts deviate from the track, the operation may be terminated immediately, and the damage is not so big. "

"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. What's more, there is a very similar place between the brain structure and the blood, that is, the material inside will flow, and its position is slightly different from that shown in the MRI. Sometimes, in order to ensure the smooth operation, we need to apply imaging technology to target the lesion

"But even if there are positioning images, there will be some errors. This requires a wealth of experience in surgical neurosurgery, to eliminate interference, surgery. This is also a problem in the promotion process of this technology, and there is no suitable solution up to now. Perhaps, the ancient meridian theory of the East can find a better revision scheme for this technique. "

When Chen Qun heard the last two sentences, he spoke highly of Professor red beard, who was more like a pirate than a surgeon.

This professor Thomson should be a pure scholar and medical expert, so he can rationally evaluate the theory of traditional Chinese medicine in China. But I'm afraid it will disappoint him. Even with the theory of meridians, I'm afraid it can't solve the problem of material flow in the brain. In order to accurately locate, more advanced technology is needed.

Another two shadowless lights are on in the operating table, and a model of human brain appears on the operating table.

With a slight bow, Professor Thomson explained the reason with regret.

"Originally, there was a demonstration patient, but unfortunately, the patient died of a sudden cerebral vascular burst one day ago. There were no patients for the scheduled demonstration operation, so we had to use props to demonstrate it for the time being. However, I found another patient whose brain lesions have not yet been completely described. It will take us a few days before we can formally perform a highly difficult operation here. At the same time, this operation will be the inventor of this technology, and my colleagues will show you. "

Hearing these words, Chen Qun understood Qi Hong's entanglement more and more. However, even if Professor Thomson wants to develop this new technology, he will try his best to provide the best operation for Feng Qiuyun. 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!"

As the red bearded pirates gave orders, two assistants inserted a laser probe with the thickness of hairspring into a flat platform with a 40 cm long glass catheter. One end of the probe, bent several radians in the air, was aimed at a fluorescent part of the brain model.

Almost at the same time, several large and small screens on the ladder classroom showed the three-dimensional data of positioning, as well as the frequency and power of the laser and the temperature of the cooling duct.

Chen Qun saw that the temperature on the laser tube was not high. With a bright green laser, it penetrated into the cooling tube, and the temperature suddenly became 13 degrees centigrade acceptable to ordinary people. The green light spot is shining on the marked fluorescence position.

As the lens zoomed in, there was a trace of smoke on the fluorescence, which could hardly be seen. Before flying, the smoke disappeared, and the fluorescence also disappeared.

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

Chen Qun felt that there was no need for him to come and study this class. Two of his simulated patients were riddled with wounds and finally died. The foreign professor must have some skills, but he hid them at this time.

He felt a loss of 100 million yuan!

Chen Qun made a quick decision, deliberately picked up the phone and took a look at it. Then he sneaked out of the classroom and rushed to the plastic surgery center as fast as he could. He has at least a dozen patients waiting for his operation.
