Director Tan is undergoing surgery, and the cervical vertebrae fracture is fixed with pedicle nails after the fracture.

After the surgical exposure and decompression were completed, Yang Ping came to insert pedicle screws with the Dimensity surgical robot.

Dr. Tan has performed more than 300 Dimensity robotic surgeries, involving fractures of the spine, pelvis and limbs, and his surgical experience is among the best in the country.

Da Vinci did laparoscopic surgery, basically using several robotic arms to complete the entire operation, and the assistant only helped to sterilize the sheets, establish the access, replace the instruments and other auxiliary work.

However, Tianji does orthopedic surgery, and cannot rely on this robotic arm to complete the entire operation, it only assists doctors to complete procedures such as image registration, preoperative planning, automatic positioning, screw placement, and postoperative verification, that is, the main work is to assist in the placement of screws, and many other jobs still need assistants to do.

If Leonardo da Vinci is an upgraded laparoscopic system, the Dimensity can be seen as an upgraded navigation device.

The original navigation equipment can only provide image navigation, and the screws need to be inserted by the main tool itself.

Now this navigation device not only provides navigation for the main knife, but also can remotely control this robotic arm to insert screws.

Because the Dimensity only had one robotic arm, the doctor nicknamed it ---One-Armed Man.

Its biggest advantage is the precise and stable placement of screws under real-time perspective navigation.

Posterior pedicle nail fixation of cervical vertebrae fracture is the most difficult and risky operation in the Dimensity robotic surgery category.

In traditional surgery, when inexperienced doctors insert cervical pedicle screws, a slight deviation can easily damage the vertebral artery or cervical spinal cord, causing serious consequences.

With Dimensity robotic surgery, the placement of screws is the same as launching a missile, it uses X-ray computer imaging technology for navigation, and the placement of screws under navigation can reach the sub-millimeter level with no mistakes at all.

This reduces the role of experience in surgery, and whether or not you are an experienced specialist, you can safely and accurately insert the screws as long as you are familiar with the machine.

Therefore, robotic surgery lowers the threshold and improves safety by placing screws.

In addition to doing the work that the robotic arm cannot do, the assistant also has an important role, once the robotic arm is out of control, the assistant can make emergency treatment.

The U.S. Food and Drug Administration released data back in 2015 saying that between 2000 and 2013, 144 patients died in robotic surgery. The reasons include "robot rampage", "short circuit misfire", "parts falling into the human body" and so on.

Director Tan put the nail open-circuit instrument on the mechanical arm, Yang Ping sat on the console, and used the tracer to start image registration, an indication line through the midline of the pedicle was drawn, the virtual screw image simulated entering the pedicle nail, the entry point, direction, route and screw diameter length were automatically calculated, the machine automatically completed the positioning, the open-circuit instrument completed the accurate open circuit, the perspective image of the machine showed that the path was very perfect, there was no deviation, Director Tan replaced the instrument, and replaced the tool and screw for implanting the screw. The robotic arm implants the screws into the pedicle of the cervical vertebrae.

Without robot assistance, this kind of operation is like planting beans, and with robot assistance, it is more relaxed.

Director Tan was a little busy, he and Dr. Zhong kept changing the instruments, and one pedicle screw after another was accurately implanted into the narrow cervical pedicle, and the whole process was completed under the navigation perspective.

Within a few minutes, the surgical step was completed, and the 3D reconstructed fluoroscopic images showed that each screw did not deviate and was encased by the bone tissue of the pedicle.

Tianji's surgery is still not as good as the Da Vinci dance, and a robotic arm is not as exciting as the operation that cooperates with each other.

For this demonstration, Manager Gu, a technical specialist of Dimensity, came to the operating room early to see if he could help.

Yang Ping didn't do much robotic surgery before, if it weren't for this competition, where would Manager Gu think of him.

Manager Gu is a middle-aged senior technician, entering the greasy period, with the shrewdness of the rivers and lakes, when he learned that Yang Ping was the best candidate to win the championship, he followed Yang Ping to see what he needed.

He contacted everywhere to let Yang Ping come to a 5G operation during the competition, at least a distance of more than 1,000 kilometers of remote control surgery, so as to show the strength of the Dimensity robot and cause a shocking effect in the competition.

However, this plan was rejected by Yang Ping, because in the current orthopedic robotic surgery, the remote control robotic arm can only complete part of the steps, and many other steps still need to be done by doctors, so that he will lose control of the entire operation.

Since he can't control the entire operation, he can't guarantee safety, which Yang Ping can't accept.

Surgery is a thing, it's right to be careful.

In order to demonstrate Tianji's ability, Manager Gu brought pencils and drawing boards for training and performance.

After Director Tan completed the remaining steps of the operation, Manager Gu loaded the pencil into the robotic arm, held the drawing board in his hand, and asked Yang Ping to spend a few letters on it casually.

Draw letters? It's too contemptuous of people.

Under the control of Yang Ping, the mechanical arm began to paint, stroke by stroke, finely outlined, and slowly, a beautiful drawing of a human skeleton appeared on the drawing board, and finally signed Yang Ping's name.

Manager Gu got the treasure, the people next to him came to see, he was afraid that others would damage the painting, this is an excellent promotional material, no matter where to display the equipment in the future, take out this painting, Tianji's strength, no need to speak, on this painting.

Can surgical robots still paint? It's the first time you've seen it.

Whether it is Leonardo da Vinci's hot dance or Tianji's human skeleton atlas, Dean Xia is now relieved that the champion of the Golden Knife Award is none other than Sanbo.

"Are you ready for the game?"

Dean Xia asked with concern.

Director Han smiled and said, "It's all ready." ”

"The case is classic, the one with the cervical vertebra fracture just now is good, as for the cost, the start-up fee for the surgical case is out of the hospital." Dean Xia is magnificent, for the Golden Knife Award champion, it's no problem to pay this money.

"I'm going to fight for a training center in your hospital? What do you think? "Manager Gu is an eye-opener, I have been with many hospitals, and I have never seen anyone so skilled in playing with his own robots.

"Played before?" Manager Gu asked cautiously.

Yang Ping saw that he always followed and sent him away: "This thing is not difficult, it is similar to a child's toy bulldozer, and it will be familiar with it after a few games." ”

Embarrassed, Manager Gu sorted out the sterile caps and masks, fifteen million high-tech, you said it was similar to a child's toy bulldozer.

Manager Gu thought about it, the words are not rough, it is such a principle, this thing is a high-end remote control toy.

It's a bit of a misnomer to call it a robot.

The Da Vinci next door is not also a high-end toy with remote control, but it has a few more robotic arms and a higher technical content.

Obviously a remote-controlled toy, why it was named a robot, even Manager Gu couldn't figure it out.
