A few days ago, the world's most advanced third-generation "Da Vinci" surgical robot arrived directly from Hubei from the United States, and successfully completed five operations on the same day. The four "arms" are flexible and move like octopus. The "finger" can change the operation mode according to the needs of the operation. It can be rotated 360 degrees and can penetrate into various parts of the human body. The "eye" three-dimensional imaging is unobstructed, and the microscopic blood vessels are clearly visible.
Only the "arm" can move flexibly, just like the octopus. The "finger" can change the operation mode according to the needs of the operation. It can be rotated 360 degrees and can penetrate into various parts of the human body. The "eye" three-dimensional imaging is unobstructed, and the microvascular enlargement is clearly visible... Recently, The world's most advanced third-generation "Da Vinci" surgical robot arrived directly from Hubei in the United States, and completed the first show in Wuhan Tongji and Xiehe hospitals. Five successful operations were completed on the same day.

The doctor just has to sit and control the robot
The two "Da Vinci" robots passed the customs at 10 pm on the 6th. They were lying in large containers and arrived in Hubei from the United States by air. The new owner of the robot is Tongji and Xiehe hospitals in Wuhan. At 10:40, the robot arrived at the hospital simultaneously.
Two hospital experts assembled robots overnight to prepare for the next day. "We are very excited and can't sleep at night." Professor Ye Zhangqun from the Department of Urology, Tongji Hospital, Wuhan, said that he had observed robotic surgery in the United States 13 years ago. His skill and skillful skills made him stunned. After returning home, he was China called for the introduction of robots first.
Wuhan Union Hospital experts vacated a special operating room to welcome the arrival of the "Da Vinci" robot, which has been busy until three in the morning. The robot parts were packed in 9 boxes, and after half an hour of loading and unloading, they reached the door of the operating room, and it took 5 hours to install and debug.
The robot was finally assembled overnight. When the huge machine stood in front of everyone waving four arms, all the experts present were conquered by it flexibly, looking forward to the first operation on the morning of the 7th.
At 8 o'clock on the 7th, the Changjiang Business Daily reporter walked into the operating room of Wuhan Union Hospital and witnessed the first "robot surgery" - cholecystectomy.
Ms. Cheng, who is lying in a hospital bed, is 41 years old. After abdominal pain, she was examined and found to have gallstones. She must be surgically removed. After anesthesia, the expert hit five small holes of 1 cm in his stomach, slowly injecting carbon dioxide, so that the abdomen was "softly" propped up by the gas, so that the robot operated more space and the doctor's vision was clearer.
The dean of the hospital, Wang Guobin, was the main knife. He placed two fingers in the “finger sleeve†in front of the console. The robot standing next to the operating table reached out through the small hole and quickly found the gallbladder. Under the operation, the "robot hand" peels off the adhesion tissue a little bit, and after separating the large blood vessels and organs, the gallbladder is removed, and the wound is hemostasis. The surgical resection time is less than half an hour.
At the same time, in Wuhan Tongji Hospital, the first beneficiary was Fang Wei (pseudonym), 65 years old, and Xiaochang, Hubei. A month ago, he was diagnosed with prostate cancer in Tongji Hospital. Due to the deep position of the prostate, ordinary laparoscopic surgery requires doctors to use a specially customized device for in-depth exploration and resection. Fang Wei heard the world's most advanced surgical robot - "Da Vinci The three generations will be introduced for the first time, so they decided to be the first to eat crabs.
At 8 o'clock on the 7th, Fang Hao officially entered the operating room. After the anesthesia is successful, the main knife expert sits on the console, and the already disinfected robot is waiting for the owner to issue a command. Just like the scene in the movie "Avatar", the expert operates the robot arm and begins surgery. One arm is a dedicated camera, which can be three-dimensional. Imaging, the remaining 3 arms can be free to change the "finger" required for surgery. For example, the scorpion, the electrocoagulation knife, the separator, the ultrasonic scalpel, etc. took only 80 minutes, and the operation of the sputum was successfully completed, and there was almost no bleeding during the operation.
Get a "driver's license" to start the robot
Wang Guobin said that the "Da Vinci" main surgery is not to say that it will replace the doctor in the future. Instead, the doctors who operate the machine are more strict.
According to Ye Zhangqun, the requirements for robot operation are very strict: firstly, you must go to Hong Kong for training, obtain a certificate to obtain a “driver's licenseâ€, and open a robot system requires a special card, and the card is an expert's information, including many years of operating experience. The hospital authorization committee recognizes and other qualifications.
At present, at Wuhan Union Hospital, four doctors and two nurses, including Dean Wang Guobin, got a license after studying in Hong Kong. The intelligent robot can only start after reading the chip card containing the doctor's qualification.
In addition, Tongji Hospital has also issued the most stringent surgeon qualifications. First, the surgery is graded, and the surgeons are graded. The expert ability database is used to automatically match the doctor's surgical qualifications. “In the end, the robot is a sophisticated tool. It is the assistant of the doctor, so the level of the doctor is particularly important," said Liao Jiazhi, vice president of the hospital.

What are the “super capabilities†of robots?
At the same time, the two major hospitals in Hubei introduced the world's most advanced "Da Vinci" robots. In terms of value, the two units totaled 40 million yuan. More importantly, it marks the surgical operation of Hubei into the "robot era."
What are the benefits that the robot will bring to the patient during surgery? How does the robot apply to medicine? Experts decipher the difference.
First used in military telemedicine
500 years ago, Da Vinci drew a robotic design, which is probably the oldest robot in the world. 500 years later, the robot named after him came to Hubei.
The Tongji Hospital of Wuhan Tongji Hospital introduced that the first to use robots was the US military and space agency. In order to prevent astronauts from getting sick in space and emergency surgery on the battlefield, they invented this telemedicine. This military technology has gradually been applied to the clinic, and has now developed into the "Da Vinci" third-generation robot.
The Da Vinci Surgical System is an advanced robotic platform. Unlike the conventional surgery performed by the surgeon, it is different from the operation of mechanized operation of the patient by computer presupposition. It is a real-time operation performed by the doctor in real time and the robot accurately mimics the human hand movement.
The Changjiang Business Daily reporter saw in the surgical space that with the doctor's finger operation on the console, the robot with four arms "Da Vinci" followed the dance, very cute.
Robot hand 360 degree flexible rotation
"The robot can make up for the shortage of manpower and operate 360 ​​degrees flexibly." Dean Wang Guobin said that the biggest advantage of "Da Vinci" is its flexible hand. The rotation of the hand and the range of motion are limited, but the "finger" of the robot can break through the limit that the human hand can't complete, realize 360-degree rotation, and arbitrarily change the operation posture in multiple dimensions in a limited space. This can be done with a scalpel, scissors, tweezers or needle holders for sutures to quickly complete cutting, electro-burning, knotting, etc., with precision and dexterity compared to human hands.
20 times 3D imaging precision protection
Surgery has evolved from open to laparoscopic surgery. The biggest advantage of the robot is that it can only be seen in many places by the doctor's eyes. The imaging of the robot is three-dimensional. At the same time, this three-dimensional imaging can be amplified by 5-10 times or even 20 times.
Wang Guobin said that ultra-clear three-dimensional imaging makes tissue, blood vessels and nerves more realistic. More importantly, in addition to breaking the human eye and manpower limitations, robotic robots and stabilizers can effectively prevent the possibility of jitter in human hands during traditional surgery. "Especially narrow anatomical areas, more patient protection" .
"Da Vinci" has a bigger advantage, that is, a small mouth. Conventional pancreatic tumor resection requires laparotomy, the wound is between 15 and 30 cm, and the wound of "Da Vinci" surgery is only about 1 cm.
Although the cost is about 40% more expensive than normal surgery, more patients are willing to choose new technology, “faster, less bleeding, less time, and better results.†Ye Zhangqun said that robotic operation can greatly reduce the physical labor of doctors. Let the doctor have better judgment.
The 10 citizens who participated in the observation at Tongji Hospital were amazed at the robots. University teacher Song said that the development of medical technology is more rapid, and the ordinary citizens have seen hope.
The "Da Vinci" robot is using a robotic arm to perform the operation. It consists of a surgeon's console, a bedside robotic arm system and an imaging system. It can “filter†the human hand to shake through the computer system, complete the movement beyond the physiological limits of the human hand, and minimize the surgical trauma.
