It was expected to take three days, but the next day, Professor He's team completed the construction of the digital model of Fang Fa's whole lower limb ahead of schedule.

The distribution points of the alignment line, osteotomy line, and fixed needle of the left lower limb are optimized by the computer, and the data calculated by the model is edited into a form that can be implanted into the main body of the surgical robot

Professor He sent his students to send the data to Yang Ping with a mobile hard drive, and with this mobile hard drive, this complex operation would be fooled.

There is no Dimensity surgical robot in the Institute of Surgery for the time being, so Yang Ping arranged Fang Faquan's surgery to be done in the surgery center.

Sanbo Hospital currently has two Dimensity surgical robots, one in the trauma orthopedic department, and one in other orthopedic departments.

Yang Ping himself was ready to buy one, but a machine cost fifteen million and needed approval.

Dean Xia has already submitted to the above for approval, and the process has almost gone through.

Three Dimensity in one hospital, this is a big customer.

When Mr. Gu, the manager of Dimensity Surgical Robot in South China, heard that Yang Ping was in charge of surgery today, he also came to the operating room early, and Dimensity and Sanbo Hospital planned to establish a training center and asked Yang Ping to come forward as an instructor.

This is all caused by the previous Da Vinci dance and the painting of Dimensity, and the two videos are still circulating on the Internet.

In particular, your Da Vinci dance is really out of the ceiling controlled by surgical robots.

The four robotic arms wrap around each other in small glass bottles, but do not touch, creating a haunting dance.

Yang Ping came to the surgery center early, and many orthopedic surgeons heard that Yang Ping came to do the operation, and everyone tried their best to find time to come and observe.

I really want to see the magic operation of the surgical robot in Yang Ping's hands.

"Hello Professor Yang!"

"Hello Professor Yang!"

"Hello Professor Yang!"

At this time, it was the peak period for doctors to enter the operating room, and all the way through, the doctors who saw Yang Ping nodded and said hello.

They had already seen a notice on the hospital's intranet that Yang Ping had been successfully promoted to associate professor.

Such a young new attending physician has been continuously promoted to deputy chief physician and associate professor.

Even if it is a low-level job and a high hire, it is very good.

What a teenager!

"Professor Yang!" Director Tan and Manager Gu came out to greet them, one left and one right to accompany Yang Ping.

Although Tan Boyun is arrogant and has a bad temper, he is a person who believes in strength.

If you are really strong, he will be convinced.

Originally, Director Tan wanted to come to the stage as an assistant, but Song Zimo and Xu Zhiliang were ready to go on stage, and there was no place for him on the operating table.

In the multi-functional operating room of the Department of Trauma and Orthopedics, the "one-armed man" Dimensity surgical robot stands quietly next to it, and the optical tracking system, the main arm host, and the main control trolley are ready.

These three parts are equivalent to the eyes, hands, and brain of a surgical robot.

Its eyes can see through and its hands are very stable.

The optical tracking system is like a "clairing eye", which looks into the depths of the musculoskeletal and monitors every aspect of the operation in real time.

The robotic arm is the "stable hand" of the robot, with flexible movement and stable operation, which can achieve sub-millimeter accuracy. Its ends can be attached to a variety of instruments, such as drills, chainsaws, screwdrivers, guides, etc., which the robot relies on to complete the operation.

The main control computer system is equivalent to the brain of the robot, which conveys the doctor's ideas to the above two devices to help the doctor carry out accurate positioning and path planning.

The surgical robot can also track the patient's movement during the operation, and the robotic arm automatically compensates for the position difference to ensure that the surgical positioning path is consistent with the planned positioning path.

The fat man was going to give Fang Fa full anesthesia, and this guy seemed to be talking to Xiao Wu about something.

"This robot won't get out of control, will it?" Fang Faquan looked at the robot in the operating room, quite worried.

Hearing that Yang Ping was going to use a robot to operate on him, he also checked some information on the Internet, and saw a case of a robot running out of control, and his heart was a little empty.

"No, don't worry, in case it gets out of control, I'll pull the plug." The little five fingers point to the switch on the wall.

Fang Faquan is still not at ease: "Does the robot have a battery?" ”

He understands that if there is battery power, it is useless for you to pull the plug.

Xiao Wu comforted him again: "If you don't bring a battery, the power will be cut off as soon as you pull it out." ”

Zhang Lin saw that Fang Faquan was crooked, and said, "Fatty, push the medicine and let him sleep." ”

Fang Faquan was even more scared now: "Don't let me sleep, didn't you say half numb?" Only numb the lower body? ”

"Then relax and don't be so nervous, this robot has successfully performed hundreds of surgeries." The fat man comforted him.

Fang Faquan dared to sleep, if he fell asleep, the robot would run wild, and there would be no way to escape by himself.

"I'm telling you, you can sleep and the operation will be done, don't be so nervous, and the anesthetic I give you generally has sweet dreams, such as in a dream, a large group of beautiful women let you choose to be a wife." Zhang Lin persuaded him to push the anesthetic to save him blindness.

Fang Fa didn't do it at all: "I'm a real person, I don't like to daydream, and I'm not interested in you giving me the emperor in my dream." ”

The guy was shivering all the time, and his heart rate on the screen was over a hundred beats per minute.

The fat man gave a little sedative, and the heart rate slowly went down.

Yang Ping walked over and said to Fang Faquan: "Relax, the name of this robot is a robot, but it is not a robot, he is a remote-controlled surgical machine, and it is all under my control." ”

Fang Faquan always thought that this robot had autonomous thinking, just like in the movie, and killed people if they disagreed.

If it's just a remote control tool, then don't worry, after all, the control is in the hands of people.

"Professor Yang, what do you mean, this robot is completely in your hands?"

Fang Faquan asked.

Yang Ping nodded: "That's right, I manipulated it, and someone was watching it." ”

I had already told him about these things before the operation, but Fang Fa forgot all about them because he was nervous.

Yang Ping didn't need to wash his hands and sat in front of the operating table.

Song Zimo took Xu Zhiliang to wash his hands and go to the stage to disinfect the order, they are assistants, and the assistants are responsible for assembling instruments on the stage and assisting the robotic arm to complete the operation.

Everything is ready to go.

"Condoms, get condoms!"

Zhang Lin shouted at the itinerant nurse.

"What are you anxious about?"

The itinerant nurse is not a vegetarian either, and she directly confronts Zhang Lin.

In fact, the so-called robot is still far from the robot, at most it is a remote-controlled surgical machine, and one or several remote-controlled robotic arms replace the doctor's hand to operate the operation.

According to the X-ray perspective, the real-time reconstruction image obtained on the screen, such as the tibia, fibula, calcaneus, talus, etc., is clear and can be rotated to get the best angle.

Several positions where the needle is placed are marked by a blue origin, and the direction of needle insertion is a straight blue line.

The robotic arm clamps the drill bit with the fixed needle, the fixed needle appears on the screen, the robotic arm automatically aligns with the origin, and then adjusts the direction so that the direction of the needle overlaps the indicated line, the calibration is completed, and then it is firmly stabilized.

The drill bit rotates at high speed, and the fixed needle enters exactly according to the specified direction, and the needle insertion point, direction, and depth are all completed exactly according to the predetermined data.

Each needle is screwed in according to this fool's method.

In the second step, Song Zimo cut the skin at the location of the proposed osteotomy and used a retractor to open the part that revealed the osteotomy.

Xu Zhiliang replaced the instrument on the robotic arm with a miniature wibble saw, and then the saw blade appeared on the screen.

The left lower limb bone in the picture, the position of the osteotomy has been marked by the blue line, and the position, length and direction have reached the sub-millimeter level.

The saw blade finds its direction and starts automatic calibration, and after calibration, the robotic arm locks and starts the osteotomy according to a fixed route.

Again, each osteotomy is performed with great precision.

Under the control of Yang Ping, the robotic arm is like flowing clouds and rhythms.

Director Tan felt that there should be music here, so he asked:

"Would you like some music?"

Song Zimo also had the same thought: "The music sounds! ”

In the corner of the operating room, there is a set of stereos, connected to a computer.

Director Tan began to look for the songs in the music library folder on the computer.

"Never give up, this is for the critically ill."

Celine Dion's "My Heart Is Eternal, a Common Song in Cardiac Surgery."

Beggies' "Stay Alive, Trauma Orthopedics Signature Music."

Britney's "Baby One More Time, the song of obstetric induce, how to put it here.

"Come back soon, the song of the emergency department celebrating the success of the rescue."

Director Tan is also a tasteful person, the soundtrack can't be casual, what kind of tune do you use?

"This patient is nervous, Coldplay's Cure You!" Song Zimo is very familiar with the music in the operating room.

Director Tan finally found the song "Cure You, Music Plays in the Operating Room."

"What kind of music does Professor Yang like to listen to during surgery?" Director Tan felt that next time he should prepare in advance.

Song Zimo said: "Mountains and Flowing Water"

"Do you want to change it?" Director Tan asked.

Song Zimo told Director Tan: "No, this song is for the patient to listen to to relieve his nervousness." ”

Finally, Song Zimo and Xu Zhiliang completed the installation of the remaining external fixing frame, put on the fixing clamp, placed the connecting rod, and tightened the nut.

A complex complete orthopedic external fixator is installed.

In fact, the Dimensity robot only completes the key steps, and many steps still need to be completed manually.

Therefore, there is still a lot of room for improvement.

The whole operation was completed in more than ten minutes, the amount of bleeding was only less than 5 ml, and the nails and osteotomy were accurately placed to keep the stable structures such as the joint capsule and ligament intact.

These intact structures will be corrected along with the correction of the bones, as well as in accordance with the Irizalov principle.

Director Tan watched the operation process and had to admit that he had completed hundreds of surgeries, but he was still not as skilled as Yang Ping, and the gap was quite large.

The gap between veteran drivers and professional racers.

It was really enjoyable to watch Yang Ping do the surgery, and the robotic arm was under his control, really doing whatever he wanted, becoming an extension of the real doctor's hand.

No wonder, he can manipulate Dimensity's robotic arm to draw a diagram of human anatomy.

You can also control Leonardo da Vinci's four robotic arms to complete that hot dance in a small glass bottle.

The music still remembered, and Yang Ping came to the side of Fang Faquan's head.

"The operation is done!"

"Success, huh?"

Fang Faquan asked worriedly, it seems that it has just begun, and it is over? I don't feel anything.

"It was a great success!"

Director Tan took over.

The music kept playing, Fang Faquan felt very comfortable, and in his mind, he walked with healthy legs and took his beautiful wife back to his small mountain village.

Sensei is so angry!

The first is the latest.
