Chapter 126 Fifteen Degrees

Adjust it by 75 degrees to form a [-]-degree angle with the nerve root. If it is too small, it will slide, but if it is too large, it will not be possible to place a tube.

The angle calculated by Yang Ping is not just talking about it, but the precise angle obtained by observing Su Nanchen's simulated puncture.

The system's super training program has cultivated Yang Ping's composition ability, which has greatly improved the accuracy of his brain and hands. This kind of accuracy is not only a mechanical measurement, but also a delicate feeling.

How can it be so accurate to puncture at 75 degrees to the nerve root, that is, to adjust fifteen degrees downward from the vertical?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 100D reconstruction image itself will have certain distortion, and the reference point is not [-]% accurate.

Just like the effective range of a sniper rifle is 2000 meters, it does not mean that the enemy will definitely be able to hit the enemy within 2000 meters. There are too many influencing 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 affirmative.

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

He tried a few more times and either the needle tip slipped away or he couldn't insert the tube.

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 hand feeling is beyond human effort.

"There is no need to be perfect. After the puncture is successful, the catheter is placed directly, and the medicine is injected 24 hours later. 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 the operation as soon as possible.

You don't have to stick to [-] points, [-] points is also a kind of 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root sheath, but the distance left is very short, there is a possibility of drug leakage, and the microcatheter may be withdrawn when the patient moves.

Although very unlikely, the possibility exists.

Su Nanchen didn't want to give up, and wanted to fight for another [-] points to reach [-] points.

Not for himself, but for the patient, to be 99 percent, never [-], 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 over the handle of the puncture needle that was exposed outside his body.

There are two puncture needles, one is thick, which is responsible for opening a tunnel on the bone tissue, and the other is thin, which enters through the sheath of the thick needle and is responsible for puncturing the nerve root sheath, and finally the microcatheter is covered with a guide wire It passed through the hollow thin needle and entered the nerve root sheath.

Yang Ping held the handle and twirled 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 bit by bit.

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

Adjust the direction of the fine needle, and penetrate the nerve root sheath at an angle of 75 degrees.

Su Nanchen handed over the microcatheter, which was threaded with a guide wire, inserted through a hollow needle, five millimeters, one centimeter, three centimeters, and entered smoothly without any bend.

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 but failed to complete, was actually completed by him in one go.

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

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

"Thank you!"

"I'm just helping you with a fifteen-degree adjustment."

The two smiled at each other.

This friend is a deal, Su Nanchen thought.

The catheter is fixed outside the skin, connected to the analgesic pump, and the anesthetic is injected from the microcatheter into the nerve sheath of chest 2.

"Ning Tianxiong, how do you feel?" Doctor Su asked the patient.

The patient is under local anesthesia and can talk awake.

"It doesn't hurt anymore!" The patient was lying on his stomach, struggling to speak.

"How is your breathing? Is it difficult?" Dr. Su asked again.

"Lying on the stomach has always been a bit strenuous." Ning Tianxiong was very cooperative.

"Blood oxygen saturation, [-]%!" said the anesthesiologist who was helping to monitor.

There is no respiratory depression, which means that the drug has not leaked, and the catheter has penetrated three centimeters, so there will be no leakage.

"Supine position, observe for 15 minutes, if there is no respiratory depression, then send back to the ward." Professor Su told Su Nanchen.

Yang Ping and Su Nanchen assisted the patient to turn over to the supine position, observed for 15 minutes, and there was no respiratory depression.

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

It was past seven o'clock, and Director Han checked the time.

Director Zhao of the Medical Office ordered the internal restaurant to prepare meals. Professor Su did not plan to stay for dinner because of the tight schedule.

Now he changed his mind and stayed for dinner.

"Thank you for your hard work, stay for a light meal before going back." Director Han insisted.

"Okay!" Professor Su said happily.

"Call Xiao Yang too!" Sujiao made a special point.

Talented people respect and cherish talents more.

Several other directors also stayed with Professor Su. After all, the dean of the attached one, the chairman of the orthopedics department, and the future academicians, no matter what their status is, they all play an important role in the medical circle. work.

The dinner was held in the restaurant inside the cafeteria. Professor Su did not drink at all, and everyone did not drink. Some had to drive, and some had surgery at night.

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

Dean Xia and Dean Sun have all come here. The Dean of the First Attached School is a bigwig in the medical field 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 Director Han accompanied Su Nanchen and Yang Ping to sit together. The two of them couldn't finish talking about how the patient was able to accurately adjust the needle at fifteen degrees from the vertical, and how this angle was calculated. 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 low voices, discussing all professional topics, and adding WeChat to each other, and other people don't care about these two young people.

"Nanchen, Uncle asked you something!" Professor Su reminded, only then did Su Nanchen realize that Dean Xia, Director Han and others were present here.

"Nanchen, come and 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 class.

Dean Xia's daughter was about the same age as Su Nanchen, and they were classmates in elementary school, but Dean Xia's daughter did not study medicine, but studied law, and worked in the provincial judicial department.

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

Dean Xia and Professor Su talked about the farm of the First Affiliated Hospital, and the two discussed taking time to take a look. The conditions were difficult in the past, and the Affiliated Hospital set up a farm in the suburbs. Everyone took turns to work and grow some food, melons, fruits and vegetables. , to make up for the shortage of living materials.

Later, this piece of land was never sold, and in the hands of Professor Su, a modern large farm was built. Every year, some vegetables, melons and fruits were given to the staff of the First Affiliated Hospital as welfare.

Yang Ping felt that this meal was very easy and rewarding. He made a friend named Su Nanchen. Su Nanchen was knowledgeable but not proud. For a case, he humbly asked Yang Ping for every detail. give up.He doesn't have any of the arrogance of the second generation.

"Contact me when you have time!" After Su Nanchen left, he even sent a WeChat message.

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

After the dinner was over, the two went to the Overseas Chinese Building to see Mr. Ning, who was smiling and comforting his daughter: "Relax, don't make it so sad, life will end eventually, it's just a matter of time, everyone can't escape."

Seeing Director Han and Yang Ping coming in, he was very happy: "Thank you two, the pain is gone, and there is no problem with breathing. I am so grateful."

Pain bothers people very much 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.

Eliminating pain has become the basic right of patients and the obligation and responsibility of medical staff.

"It's comfortable!" Mr. Ning leaned against the head of the bed, holding a "Visual Analog Pain Rating Scale" in his hand, the muscles on his face were relaxed, without the previous distortion.

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

"Thank you, Professor Han! Don't worry!" Mr. Ning shook hands with Director Han.

When shaking hands with Yang Ping, he said: "Dr. Yang and Dr. Su helped me puncture, and finally it seems that the angle needs to be corrected, [-] degrees, and Dr. Yang operated it."

"I'm awake and listening all the time." Mr. Ning explained with a smile.

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

"Thank you very much for allowing me to sit here and talk with a smile." Mr. Ning was in good spirits.

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

Before eating, Yang Ping sent a WeChat message to Xiao Su.

I didn't read Xiao Su's WeChat just now.

　Thank you Yizhenliangsheng and Lihentian for your reward!Thank you all!
