The operation that Director Tan is performing is posterior pedicle screw fixation of cervical spine fracture.
After the surgical exposure, decompression, etc. were completed, it was time for Yang Ping to use the Tianji surgical robot to insert the pedicle screws.
Director Tan has completed more than 300 Tianji robotic surgeries, involving fractures of the spine, pelvis and limbs. His surgical experience is 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 with sterilizing the drapes, establishing the approach, changing instruments and other auxiliary work.
When Tianji performs orthopedic surgery, it cannot rely on this robotic arm to complete the entire operation. It only assists the doctor in completing image registration, preoperative planning, automatic positioning, screw placement, postoperative verification and other procedures. That is, the main job is to assist
Inserting screws and many other tasks still require assistants.
If Da Vinci is an upgraded laparoscopic system, Dimensity can be regarded as an upgraded navigation device.
The original navigation equipment can only provide image navigation, and the screws need to be inserted by the surgeon himself.
Now this navigation device not only provides navigation for the surgeon, but can also remotely control the robotic arm to insert screws.
Because Tianji only has one robotic arm, the doctor gave it a nickname---The One-Armed Man.
Its greatest 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 operation among Tianji robotic surgeries.
In traditional surgery, when inexperienced doctors insert cervical pedicle screws, slight deviations can easily damage the vertebral artery or cervical spinal cord, causing serious consequences.
Using Tianji robotic surgery, inserting screws is like launching a missile. It uses X-ray computer imaging technology for navigation. The accuracy of inserting screws under navigation can reach the sub-millimeter level, and there will be no mistakes at all.
This reduces the role of experience in surgery. Regardless of whether you are an experienced expert or not, as long as you are familiar with the machine, you can place screws safely and accurately.
Therefore, robotic surgery lowers the threshold for inserting screws and improves safety.
In addition to doing work that the robotic arm cannot do, the assistant also has an important role. Once the robotic arm loses control, the assistant can provide emergency treatment.
As early as 2015, the U.S. Food and Drug Administration released data stating that between 2000 and 2013, 144 patients died during robot surgery. The reasons include "robot runaway", "short circuit misfire", and "parts"
Fall into the human body" etc.
Director Tan installed the screw-opening instrument on the robotic arm. Yang Ping sat on the console and used the tracer to start image registration. An indicator line was drawn through the midline of the pedicle, and the virtual screw image was simulated.
When entering the pedicle screw, the entry point, direction, route and screw diameter and length are automatically calculated. The machine automatically completes the positioning. The opening instrument completes precise opening. The machine's perspective image shows that the path is perfect and there is no deviation. Director Tan replaces the instrument.
, replace the screw implanting tools and screws, and the robotic arm implants the screws into the cervical pedicle.
Without robot assistance, this kind of surgery would be 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 instruments, and one pedicle screw after another was accurately implanted into the narrow cervical pedicle. The whole process was completed under navigation fluoroscopy.
Within a few minutes, this surgical step was completed, and the three-dimensional reconstructed fluoroscopic image showed that each screw had not deviated and was wrapped by the bone tissue of the vertebral pedicle.
Tianji's surgery is still not as entertaining as Da Vinci's Dance, and a robotic arm does not have the excitement of coordinated operations.
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 had not performed many robotic surgeries before. If it hadn't been for this competition, Manager Gu would never have thought of him.
Manager Gu is a middle-aged senior technician who has entered the greasy stage and has a shrewd mind. When he learned that Yang Ping was the best candidate to win the championship, he followed Yang Ping to see what he had in store.
Requirements.
He contacted everyone and asked Yang Ping to use a 5G surgery to remotely control the surgery at least a thousand kilometers away during the competition. Only in this way could he demonstrate the strength of Tianji Robot and create a shocking effect in the competition.
However, this plan was rejected by Yang Ping, because in the current orthopedic robotic surgery, the remote-controlled robotic arm can only complete part of the steps, and many other steps still need to be done by the doctor, so that he will lose control of the entire surgery.
Since he cannot control the entire operation, he cannot guarantee safety, which Yang Ping cannot accept.
You have to be careful when it comes to surgery.
In order to demonstrate Tianji's abilities, Manager Gu brought pencils and drawing boards used for training and performance.
After Director Tan completed the remaining steps of the operation, Manager Gu installed the pencil on the robotic arm, held the drawing board in his hand, and asked Yang Ping to write a few letters on it.
Drawing letters? That’s so disrespectful.
Under the control of Yang Ping, the robotic arm began to draw, stroke by stroke, and outline it carefully. Slowly, a beautiful picture of human skeleton appeared on the drawing board, and finally Yang Ping's name was signed.
Manager Gu felt like he had found a treasure. The people nearby came over to look at it. He was afraid that others would damage the painting. This was an excellent promotional material. No matter where he went to display equipment in the future, he would take out this painting and Tianji's strength would show.
, no need to waste words, just put it in this painting.
Can a surgical robot also paint? This is the first time everyone has seen it.
Whether it's Da Vinci's dance or Tianji's human skeleton atlas, Dean Xia is now very confident that the winner of the Golden Knife Award is none other than Sanbo.
"Are the competition cases ready?"
Dean Xia asked with concern.
Director Han said with a smile: "Everything is ready."
"Choose classic cases, the one with cervical vertebra fracture just now is good. As for the cost, the hospital will pay for the start-up fee for surgical cases." Dean Xia was grand. For the Golden Knife Award winner, there is no problem in paying this amount.
"I'm going to fight for it and set up a training center in your hospital? How about it?" Manager Gu was an eye-opener. He has worked with many hospitals, but he has never seen anyone who is so proficient in using their own robots.
"Have you played before?" Manager Gu asked carefully.
Seeing that he always followed, Yang Ping dismissed him: "This thing is not difficult. It is similar to a child's toy bulldozer. You will get familiar with it after playing with it for a few times."
Embarrassed, Manager Gu sorted out the sterile caps and masks. Fifteen million of high-tech stuff, you said, it’s similar to a child’s toy bulldozer.
Manager Gu thought about it for a while, whether it was rough or not, that's the principle. This thing is a high-end remote control toy.
To call it a robot is a bit unworthy of the name.
The Leonardo da Vinci next door is not only a high-end remote control toy, it just has a few more robotic arms and is a bit more technical.
Even Manager Gu couldn't figure out why a remote-controlled toy was called a robot.
"How about setting up a Tianji training center in Sanbo?" Manager Gu got back to business.
Director Han, Director Tan and Dean Xia were all there, he asked tentatively.
Yang Ping thinks it is feasible. To operate a surgical robot well, it still needs a certain period of formal training. He just said toys as a joke.
Yang Ping is happy to train others, improve their skills, reduce surgical risks, and improve surgical safety.
"How about? Set up a training center?" Dean Xia asked Yang Ping.
Director Tan was afraid that Yang Ping would refuse him, so he answered for him first: "This is a good thing---"
Yang Ping also means this: "Good thing!"
"Good thing! It's settled. You go prepare, act quickly, and don't delay for several months without being able to get your license plated." Dean Xia turned to Manager Gu and said.
"As soon as possible, as soon as possible!" Manager Gu said immediately.
