The latest website: "Professor Chu, what kind of inspections do you have to do before surgery?" Zhou Guohui asked.

"Use SIGNA; 3.0T MRI to scan the head before surgery, import the scanned images into the preoperative planning system, and use the surgical planning system to plan the surgical target. There is no special preparation. The key point is the selection of target coordinates."

Zhou Guohui knows what Chu Zhixi said, but in neurosurgery operations, things that are far from the slightest error often happen. Humans do not have much research on the brain, and neurosurgery was a forbidden area decades ago.

The research on the brain has been developed rapidly in the last 2 or 30 years.

What Chu Zhixi said is simple, but the operation is not the case. She vaguely passed the most difficult step, but Zhou Guohui did not ask carefully, but focused on Chu Zhixi's operation.

"First use 2% lidocaine to perform local anesthesia on the patient, install a standard Leksell stereotactic head frame, and perform a head CT scan after fixation. The scanned images are fused into the preoperative planning system to calculate the target parameters. My brother is now doing part of it. The job is to modify the preoperative planning system to automatically determine the coordinates of the target point."

"..." Zhou Guohui knew that his guess was correct.

What Chu Zhixi said is very simple, vegetative awakening and even later Alzheimer's disease can be calculated with a computer. When mature, there is no need for manual operation at all, and the computer can complete it accurately.

This is already similar to the black technology of the future world.

"Assuming that the coordinates of the target point have been selected, we come to surgery. The new system will specify the needle insertion route, so just operate it. In fact, my brother said that the robot is better to operate, because the robot only follows a fixed procedure, and there is no self-awareness. The chance of a problem is much smaller."

"However, there seems to be no discussion on this aspect of the current domestic physician law. It is difficult to amend the physician law... My brother said it is difficult, and we have to wait for academic acceptance and social acceptance. Optimistically, it will be at least 10 years from now."

"Make a straight or curved incision of about 4-5cm on the scalp along the path of the puncture point. I prefer the curved incision, but it is recommended that you choose a slightly longer straight incision when operating."

Watching Chu Zhixi fix the head with the Leksell stereotactic head frame and then modify the positioning, Zhou Guohui knows that the angle of the Leksell stereotactic head frame is the result of calculation, and a little error will cause fatal injuries.

Chu Zhixi's operation is very stable and gentle.

Leksell stereotactic head frame fixed the head without repeatedly adjusting the angle and direction. Then he took the scalpel and made an arc-shaped incision on the model.

After blunt separation, electric heating to stop the bleeding, the anatomy level was clear, and the skull was quickly reached.

"After exposing the patient's skull, drill a 14mm bone hole in the skull. You need to understand this step, and you need to understand the feel." Chu Zhixi said.

"Is it a sense of emptiness?"

"Well, it's like doing a cerebrospinal fluid puncture. It feels like a puncture. Our hospital has a 3D printed model, so you can practice it again and again if you have time. This step must be sure to be foolproof. wall."

"..." Zhou Guohui heard Chu Zhixi's description again and again.

This tone of speech is not like what Chu Zhixi said, but rather like Wu Mian's way of speaking. It is estimated that when Wu Mian taught Chu Zhixi to perform the operation, he told her so and asked her to be cautious.

"Professor Chu, how many cases have you mastered after doing?" Zhou Guohui asked.

"Does it feel? I have mastered it after one case. My brother said that I am a girl and have a natural instinct." Chu Zhixi said casually.

"..."

"That was a white mouse for experiment, a special electric drill, it felt very clear, felt the pressure change, and then stopped. But I see it is very difficult for others to do this step, I don't know how other people feel, very Is it simple?"

Simplicity... It turns out that Professor Chu said that the simplicity is the truth, and Zhou Guohui is a little at a loss.

"Then it is to cut the patient's meninges and make a 2mm incision after electrocoagulation in the cerebral cortex." Chu Zhixi did not stop, but did it step by step.

Cut open the meninges and see the vivid brain. In Zhou Guohui's view, this is not a model at all, it is simply a real operation.

But when his gaze swept to the operating table, the operating table was empty, with only a head on the head frame, but no body.

"Slowly implant the puncture needle according to the coordinates. The trajectory of the puncture needle is fixed. The entire puncture process only needs to be punctured slowly along the established track. Director Zhou, isn't it easy?" Chu Zhixi pulled out after the puncture was completed. Out of the needle core, he said.

simple? Simple wool!

Implant electrodes and perform external electrical stimulation. Because it is only surgical training, there is no body, so doing this step will stop. Next, let's look at the patient's reaction, nerve reflexes, and so on, but there are no steps.

"Under normal circumstances, when external electrical stimulation is performed, we can see that the patient's symptoms such as tremor, stiffness, and slowness of movement will be significantly improved. After the test results are completed, we need to remove the puncture needle, leave the electrode in the skull, and then suture the incision. The first phase was successfully completed."

"How to do the second stage?" Zhou Guohui asked.

"The second stage is the implantation of the pulse generator. This stage is also relatively simple, but because our extension cord needs to be passed through the subcutaneous tunnel, it will be more painful if we choose to complete it under local anesthesia, so at this stage we will Finished under Ma."

"Wait!" Zhou Guohui discovered a problem he hadn't noticed.

"What's wrong, Director Zhou?"

"The first stage was completed under local anesthesia?" Zhou Guohui asked.

"Yes." Chu Zhixi said naturally, "The patient is awake at this stage and can clearly feel the effect of the implanted electrode. Some fine-tuning is done by the patient's response."

"For example..."

Chu Zhixi talked a lot, UU reading www. There are some examples on uukanshu.com that Zhou Guohui has never heard of. But he still couldn't accept the setting of local anesthesia and craniotomy, it was too cruel!

"Professor Chu, what should I do if the patient is scared and disturbed?" Zhou Guohui asked.

"Emmmmmm..." Chu Zhixi was taken aback, and said with some distress, "This is indeed the most difficult step."

Zhou Guohui looked at Chu Zhixi, waiting for her explanation.

But when Chu Zhixi said this, it was as if he had forgotten about it and started sewing.

"Professor Chu, how did you solve it?" Zhou Guohui asked.

"I haven't encountered it before." Chu Zhixi said, "Every time I do deep brain stimulation, my brother gives the patient shallow hypnosis, and the operation goes well."

"..."

That's it, you tell me the operation is easy? Zhou Guohui couldn't laugh or cry.
