The Godfather of Surgery

Adjust it by 15 degrees to form a 75-degree angle with the nerve root. If it is too small, it will slide, but if it is too large, it cannot be placed.

The angle calculated by Yang Ping was not a rhetoric, but an accurate angle obtained by observing Su Nanchen's simulated puncture.

The system's super training program, the training of Yang Ping's composition ability, has improved his accuracy a lot, whether it is his brain or his hands. This accuracy is not only a mechanical measurement, but also has a delicate feeling.

How can it be so precise that it is punctured at a 75-degree angle to the nerve root, that is, it is adjusted 15 degrees from the vertical to the bottom? Su Nanchen was puzzled.

The accuracy of navigation can be accurate to a few tenths of a millimeter, but that is only theoretical accuracy. The three-dimensional reconstructed image itself will have a certain distortion, and the reference point is not 100% accurate.

Just like the effective range of a sniper rifle is two kilometers, it does not mean that it will definitely be able to hit the enemy within two kilometers. There are too many factors.

As long as it forms a 75-degree angle with the nerve root, it will definitely succeed. Yang Ping reminded again in a low voice, his tone affirmed.

Su Nanchen didn't have much confidence, so he couldn't be so precise.

He tried several more times, and either the needle tip slipped or the tube couldn't be placed.

Professor Su also saw the problem. The puncture needle is hard and the guide wire is elastic. If the direction is not optimal, the adhesion cannot be broken through. The required feel is no longer a human effort.

There is no need to be perfect. After the puncture is successful, the catheter is placed directly, and the drug is injected after 24 hours. The microcatheter and the surrounding nerve sheath will form a biological seal, and the possibility of leakage is very low! Professor Su asked Su Nanchen to end it as soon as possible. Operation.

You don't have to stick to 100, 80 is also a success.

If the puncture is successful, the catheter is placed directly, and the microcatheter is also left in the nerve root sheath, but the distance is very short, which may cause drug leakage, or the microcatheter may be withdrawn when the patient moves.

Although the odds are very low, the possibility exists.

Su Nanchen didn't want to give up, and wanted to fight for another 20 points to reach 100 points.

Not for himself, but for the patient, to be able to be one hundred, never ninety-nine, this is his philosophy.

Are you sure? Su Nanchen asked Yang Ping.

Yang Ping nodded.

The two had a brief conversation, exchanged glances, then turned around and exchanged positions back to back.

Su Nanchen let go, and Yang Ping took the handle of the puncture needle that was exposed outside the body.

There are two puncture needles, one thick, which is responsible for opening a tunnel in the bone tissue, and one thin, which enters from the sheath of the thick needle and is responsible for puncturing the nerve root sheath, and finally the microcatheter is sheathed with a guide wire Only through the hollow thin needle, into the nerve root sheath.

Yang Ping held the handle and twisted the fine needle in his hand to find the feeling. The dynamic three-dimensional anatomical map in his mind was presented, and the details were perfected little by little.

The needle in the hand, which also appears in the brain, has a more realistic relationship with nerve roots than navigation.

Adjust the direction of the fine needle, pierce the nerve root sheath at a 75-degree angle.

Su Nanchen handed over a microcatheter with a guide wire threaded through it and entered from a hollow needle, five millimeters, one centimeter, three centimeters, and entered smoothly without any bending.

This means that the guide wire and microcatheter have successfully broken through the adhesion, entered the nerve sheath, and penetrated three centimeters.

The balloon in the bony tunnel of the pedicle is inflated and the catheter is secured.

What Su Nanchen tried several times and failed to accomplish was actually completed by him at one time.

Professor Su nodded slightly, and looked at Yang Ping with admiration, and his love for talent suddenly rose.

The two turned around and exchanged positions again. Yang Ping returned the following actions to Su Nanchen. Su Nanchen slowly pulled out the fine needle and the thick needle for the puncture, and finally pulled out the guide wire, and the puncture was completed.

thanks!

I'm just helping you complete the fifteen-degree adjustment.

The two smiled at each other.

This friend is settled, Su Nanchen thought.

The external fixation catheter was connected to the analgesic pump, and the anesthetic was injected from the microcatheter into the nerve sheath of chest 2.

Ning Tianxiong, how are you feeling? Dr. Su asked the patient.

The patient is under local anesthesia and can converse consciously.

It doesn't hurt anymore! The patient was in a prone position, struggling to speak.

How is breathing, is it difficult? Dr. Su asked again.

It's been a little laborious to lie down. Ning Tianxiong cooperated very well.

Oxygen saturation, 100 percent! said the anesthesiologist who was helping with monitoring.

There is no respiratory depression, indicating that there is no leakage of the drug, the catheter has penetrated three centimeters, and no leakage will occur.

Supine position, observe for 15 minutes, no respiratory depression, and then return to the ward. Professor Su told Su Nanchen.

Yang Ping and Su Nanchen assisted the patient to turn over and turn into a supine position, and observed for fifteen minutes without respiratory depression.

An extremely difficult puncture was successfully completed by two young people, and it was perfect. The technical content of this puncture was equivalent to the decapitation of the special forces in the war, and it was all technical work.

It's past seven o'clock, Director Han is checking the time.

Director Zhao of the Medical Department instructed the internal restaurant to prepare meals. Professor Su did not plan to stay for dinner because of the time constraints.

Now he had changed his mind and stayed for dinner.

It's hard work, stay for a quick meal and go back. Director Han insisted.

Okay! Professor Su cheered.

Call Xiao Yang too! Su Jiao deliberately proposed.

Talented people respect and cherish talents more.

Several other directors also stayed to accompany Professor Su. After all, the dean of the first attached, the chairman of the department of orthopedics, and the future academicians, no matter who they are, all play an important role in the medical circle. This face cannot be refuted. work.

The dinner is set in the restaurant inside the cafeteria. Professor Su doesn't drink a drop of alcohol, and everyone doesn't drink alcohol. Some have to drive, and some have surgery at night.

In addition to Director Han, Director Tian, ​​Director Tan, Director Qin from the Spine Surgery Department of Sanbo Hospital, Director Gao from the Department of Sports Medicine, and Director Chang from the Department of Joint Surgery all came to accompany him.

Dean Xia and Dean Sun have all come here. The Dean of Attached One is a big man in the medical world and cannot be neglected. Besides, Dean Xia and Professor Su are in the same school, they used to work together, and they have a certain friendship.

Dean Xia and Dean Han accompanied him, Su Nanchen pulled Yang Ping to sit together, and the two of them had a lot to say about how the patient just now could accurately adjust the needle by 15 degrees from the vertical, and how to calculate this angle. of.

The dining table was divided into two circles, one for Su Nanchen and Yang Ping, and one for the others.

Su Nanchen and Yang Ping have been chatting in a low voice, and the discussions are all professional topics. They also add WeChat to each other, and others ignore the two young people.

Nan Chen, uncle is asking you something! Professor Su reminded Su Nanchen that there was Director Xia, Director Han and others in the room.

Nan Chen, come to play at home when you have time. Dean Xia said.

Dean Xia and Professor Su both graduated from Nandu Medical University, and they were still in the first term. Dean Xia was also transferred from the first year. When they were young, they both lived in the old dormitory of Nandu Medical University, when Su Nanchen was still in elementary school.

Dean Xia's daughter is about the same age as Su Nanchen. The two are classmates in elementary school, but Dean Xia's daughter has not studied medicine, but has studied law and works in the provincial justice department.

Okay, thank you Uncle Xia. Su Nanchen was generous and decent, then lifted the teapot, poured tea for the seniors, and raised a glass to everyone.

Dean Xia and Professor Su talked about the farm of the First Affiliated Hospital. The two discussed taking the time to visit. The conditions were tough before. , to make up for the shortage of living materials.

Later, this piece of land was never sold. In the hands of Professor Su, a large modern farm was built. Every year, the employees of the First Affiliated Hospital would be given some vegetables, fruits, etc., which was considered a welfare.

Yang Ping felt that this dinner was very easy and the harvest was great. He made a friend of Su Nanchen. Su Nanchen was very knowledgeable, but not proud. For a case, he humbly asked Yang Ping for every detail. give up. He doesn't have some of the arrogant vices of the second generation at all.

Contact more when you have time! After Su Nanchen left, she sent WeChat over.

Professor Su appreciates you very much, Xiao Yang! Director Han hummed a tune, very happy.

After the dinner, the two went to the Overseas Chinese Building to see Mr. Ning. He was smiling and comforting his daughter: Take it easy, don't make it so sad, life will end in the end, it's just the difference in time, and everyone can't escape.

Seeing Director Han and Yang Ping coming in, he was very happy: Thank you two, it's no longer painful, and there is no problem with breathing, I'm so grateful.

Pain is very troublesome to people and is the most unbearable symptom for patients. The World Health Organization has listed pain as the fifth vital sign after heart rate, respiration, blood pressure and body temperature.

Pain relief has become the basic right of patients and the duty and responsibility of medical staff.

Relaxed! Mr. Ning leaned against the head of the bed, holding a Visual Analogue Pain Scale in his hand. The muscles on his face were relaxed and there was no previous distortion.

Thank you all! Thank you Director Han, thank you Doctor Yang! Thank you, really! Miss Ning stood up and bowed.

Thank you, Professor Han! For your trouble! Mr. Ning shook hands with Director Han.

When shaking hands with Yang Ping, he said, Dr. Yang and Dr. Su helped me with the puncture. In the end, it seems that I have to correct the angle, fifteen degrees, and Dr. Yang did it.

I'm awake and have been listening. Mr. Ning explained with a smile.

Under local anesthesia, he was lying on the operating bed, listening to the doctor's conversation all the time, and was very clear about the operation process.

Thank you so much for letting me sit here and talk with a smile. Mr. Ning was in good spirits.

Well, go back to rest early after eating, and don't drink.

Before eating, Yang Ping and Xiao Su sent WeChat.

Xiao Su returned to WeChat, which she hadn't read just now.

Thanks for the reward of Yi Pillow Liang Sheng and Li Hentian! Thank you all!
