godfather of surgery

Chapter 391 The painting of Tianji
The operation Director Tan is doing is the posterior pedicle screw fixation of the cervical spine fracture.

After the surgical exposure and decompression were completed, it was time for Yang Ping to use the Tianji surgical robot to place the pedicle screws.

Director Tan has completed more than [-] Tianji robotic surgeries, involving fractures of the spine, pelvis, and limbs. His surgical experience is considered to be at the forefront in the country.

Da Vinci performed laparoscopic surgery, basically using several robotic arms to complete the entire operation, and the assistants only helped with disinfection and laying of the sheets, establishment of access, and replacement of instruments and other auxiliary tasks.

For orthopedic surgery, Tianji cannot rely on this robotic arm to complete the entire operation. It only assists doctors in image registration, preoperative planning, automatic positioning, screw placement, and postoperative verification. Inserting the screws, many other tasks still need assistants to do.

If Da Vinci is an upgraded version of the laparoscopy system, Dimensity can be regarded as an upgraded version of the navigation device.

The original navigation equipment can only provide image navigation, and the screw needs to be inserted by the surgeon himself.

Now this navigation device not only provides navigation for the chief surgeon, but also remotely controls the robotic arm to insert screws.

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

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

Posterior pedicle screw fixation of cervical spine fractures is already the most difficult and risky surgery among the types of Tianji robotic surgery.

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

Using Tianji robot surgery, inserting screws is like launching missiles. It uses X-ray computer imaging technology for navigation. Under navigation, the accuracy of screw insertion can reach sub-millimeter level, and there will be no mistakes at all.

This reduces the role of experience in surgery. Whether it is an experienced expert or not, as long as he is familiar with the machine, he can insert the screw safely and accurately.

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, stating that between 2000 and 2013, 144 patients died in robotic surgery.The reasons include "robot runaway", "short circuit fire", "parts fall into the human body" and so on.

Director Tan installed the open-circuit device for placing the screws on the mechanical arm, Yang Ping sat on the console, and started image registration with the tracer, drawing an indicator line through the midline of the pedicle, and the 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 opening device completes the precise opening. The fluoroscopic image of the machine shows that the path is perfect and there is no deviation. Director Tan replaces the device , replace the tool and screw for implanting the screw, and the robotic arm implants the screw into the cervical pedicle.

Without robot assistance, this kind of operation Yang Ping is like planting beans, but with robot assistance, it is easier and more comfortable.

Director Tan was a little busy. He and Dr. Zhong kept changing instruments, and one after another pedicle screws were precisely implanted into the narrow cervical pedicles. The whole process was completed under navigation fluoroscopy.

In a few minutes, this surgical step was completed, and the [-]D reconstructed perspective image showed that each screw was not deviated and was wrapped by the bone tissue of the pedicle.

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

For this demonstration, Tianji Technical Specialist Manager Gu came to the operating room early to see if he could be of any help.

Yang Ping didn't do many robot surgeries before, if it wasn't for this competition, Manager Gu wouldn't think of him.

Manager Gu is a middle-aged senior technician, who has entered the greasy period, and has a shrewdness in the world. 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 have a 5G surgery during the competition, at least a distance of more than [-] kilometers for remote surgery, so that he could demonstrate the strength of the Tianji robot and create a shocking effect in the competition.

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

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

Be careful with surgery.

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 installed the pencil on the mechanical arm, holding the drawing board in his hand, and asked Yang Ping to write a few letters on it.

Draw letters?It's so contemptuous.

Under the control of Yang Ping, the robotic arm began to draw, one stroke at a time, delicately outlined, and slowly, a beautiful picture of human bones appeared on the drawing board, and finally signed Yang Ping's name.

Manager Gu felt as if he had found a treasure, and the people next to him came over to look at it. He was afraid that others would damage the painting. , no need to waste a word, just put it on this painting.

Can Surgical Robots Still Paint?It's the first time everyone sees it.

Whether it's Leonardo da Vinci's hot dance or Tianji's human skeleton atlas, Dean Xia is now very relieved that the winner of the Golden Knife Award must be San Bo.

"Is the match case ready?"

Dean Xia asked with concern.

Director Han said with a smile, "It's all ready."

"Choose the classic case. The one with the cervical vertebrae fracture just now is not bad. As for the cost, the hospital will pay for the start-up fee for the surgical case." Dean Xia said generously, for the Golden Knife Award champion, it is no problem to pay this money.

"I'll fight for it, 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 someone who is so proficient in playing with his own robot.

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

Seeing that he was always following, Yang Ping sent him off: "This thing is not difficult, it's similar to a child's toy bulldozer. You can get used to it after a few games."

Embarrassed, Manager Gu tidy up the sterile cap and mask, 500 million high-tech, you said it is similar to a child's toy bulldozer.

Manager Gu thought about it for a while, and the reasoning was 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 also a high-end remote-controlled toy, but with a few more robotic arms and a higher technical content.

Even Manager Gu couldn't figure out why it was named a robot for a remote control toy.

"How about setting up a Tianji training center in Sanbo?" Manager Gu returned to the subject.

Director Han, Director Tan and Dean Xia were all there, and 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 said that the toy was just a joke.

Yang Ping is willing to do this by training others, improving their level, reducing the risk of surgery, and improving the safety of surgery.

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

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

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

"Good thing! It's settled like that. You guys go to prepare and act quickly. Don't procrastinate for a few months and fail to get the card." Dean Xia turned to Manager Gu and said.

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