Chapter 391 The Painting of Tianji

The operation that Director Tan is doing is the posterior pedicle screw fixation of the cervical spine fracture.

After the exposure and decompression of the operation were completed, it was time for Yang Ping to use the Dimensity surgical robot to insert the pedicle screws.

Director Tan has completed more than 300 surgeries with the Dimensity robot, involving fractures of the spine, pelvis and limbs. His surgical experience is considered to be at the forefront of the country.

When Da Vinci performed laparoscopic surgery, he basically used several robotic arms to complete the entire operation. The assistant only helped to sterilize and lay out sheets, establish an approach, and replace instruments.

For orthopedic surgery, Dimensity 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 job is to assist Inserting screws, many other tasks still need assistants to do.

If Da Vinci is an upgraded laparoscopic system, Dimensity can be regarded as an upgraded navigation device.

The original navigation device can only provide image navigation, and the screw needs to be inserted by the main tool.

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

Because Dimensity has only one mechanical arm, the doctor gave it a nickname - the one-armed man.

Its greatest advantage is accurate and stable screw placement under real-time fluoroscopic navigation.

Posterior pedicle screw fixation for cervical vertebra fractures is already the most difficult and risky operation among Dimensity robotic surgeries.

In traditional surgery, when an inexperienced doctor inserts a cervical pedicle screw, a slight deviation may easily damage the vertebral artery or cervical spinal cord, causing serious consequences.

Using Dimensity robotic surgery, inserting screws is the same as launching missiles. It uses X-ray computer imaging technology for navigation. Under navigation, screws are inserted, and the accuracy can reach sub-millimeter level, and there will be no mistakes at all.

This reduces the role of experience in surgery, as experienced specialists, whether experienced or not, can place screws safely and accurately as long as they are familiar with the machine.

Therefore, robotic surgery lowers the threshold for screw placement and improves safety.

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 as early as 2015 that between 2000 and 2013, 144 patients died from robotic surgery. The reasons include "robot runaway", "short circuit fire", "parts falling into the human body" and so on.

Director Tan installed the open-circuit instrument for screw placement on the robotic arm, Yang Ping sat on the console, used the tracer to start image registration, and drew an indicator line through the midline of the pedicle, virtual screw image simulation After entering the pedicle screw, the entry point, direction, route and screw diameter and length are automatically calculated, the machine automatically completes the positioning, and the circuit opening device completes the precise opening. The fluoroscopic image of the machine shows that the path is perfect without any deviation. , replace the tool and screw for implanting the screw, and the robotic arm implants the screw into the cervical pedicle.

Without robot assistance, Yang Ping's surgery is like planting beans. With robot assistance, it is easier and more comfortable.

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

In a few minutes, the procedure was complete, and the 3D-reconstructed fluoroscopic images showed that each screw had not deviated, encased in the bony tissue of the pedicle.

Dimensity's operation is still not as good as Da Vinci's hot dance, and the operation of a robotic arm and no mutual cooperation is exciting.

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

Yang Ping had not done many robotic surgeries before. If it weren't for this competition, how would Manager Gu think of him.

Manager Gu is a middle-aged senior technician, entering the greasy period, with the shrewdness of all corners of the country. When he learned that Yang Ping was the best candidate to win the championship, he followed Yang Ping to see what he had. need.

He contacted everywhere and asked Yang Ping to perform a 5G surgery during the competition, at least a thousand kilometers away from remote control surgery, so as to show the strength of the Dimensity robot and cause a shocking effect in the competition.

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

Since the entire operation cannot be controlled, the safety cannot be guaranteed, which is unacceptable to Yang Ping.

Surgery, be careful.

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

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

draw letters? Too contempt for people.

Under the control of Yang Ping, the robotic arm began to paint, stroke by stroke, outlining it finely. Slowly, a beautiful picture of human skeleton appeared on the drawing board, and finally signed the name of Yang Ping.

Manager Gu is like a treasure, and the people next to him come to see it. He is afraid that others will damage the painting. This is an excellent publicity material. No matter where you go to exhibit equipment in the future, take this painting out. The strength of Dimensity , do not hesitate to put it on this painting.

Can surgical robots still paint? It was the first time everyone saw it.

Whether it's Da Vinci's hot dance or Dimensity's human skeleton map, Dean Xia is now very relieved that the winner of the Golden Knife Award is Sanbo.

"Are the game cases ready?"

Dean Xia asked with concern.

Director Han smiled and said, "Everything is ready."

"Choose the classic case. The one with the fracture of the cervical vertebra just now is not bad. As for the cost, the hospital will pay for the start-up of the surgical case." President Xia said, for the winner of the Golden Knife Award, there is no problem with paying this amount of money.

"I'm going to fight for it to set up a training center in your hospital? How about it?" Manager Gu was an eye-opener. He has followed many hospitals, and he has never seen such a skilled robot.

"Have you played before?" Manager Gu asked carefully.

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

Embarrassed, Manager Gu sorted out the sterile caps and masks. The 15 million high-tech, you said, is similar to a child's toy bulldozer.

Manager Gu thought about it for a while, and the reasoning is not rough. That's the 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 a high-end remote control toy, but it has a few more robotic arms, and the technical content is higher.

Even Manager Gu couldn't understand why a remote control toy was named a robot.

"Get a Dimensity training center in Sanbo? How about it?" Manager Gu got back to business.

Director Han, Director Tan, and Director Xia were all there, he asked tentatively.

Yang Ping thinks it is feasible. To operate the surgical robot well, it still needs to go through a certain period of formal training. He just talked about toys and it was just a joke.

Yang Ping is willing to do this to train others, improve their level, reduce the risk of surgery, and improve the safety of surgery.

"How? Set up a training center?" Dean Xia asked Yang Ping.

Director Tan was afraid of Yang Ping's rejection, so he answered for him first: "This is a good thing——"

Yang Ping also has this meaning: "Good thing!"

"Good thing! It's settled, you go to prepare, act wisely, don't procrastinate for a few months and can't get on the card." Dean Xia turned his head and said to Manager Gu.

"As soon as possible, as soon as possible!" Manager Gu said immediately.
