Robot "doctor" walks into surgery room

As was born in science fiction, people are full of illusions about robots. Perhaps it is due to the vague definition of robots that gives people sufficient room for imagination and creation. Today, it has new skills, that is to help doctors complete the surgery. The first surgery performed in Zhejiang Province using the "Da Vinci" robot was completed on the morning of September 11th at the First Affiliated Hospital of Zhejiang University Medical College. Zheng Shusen, dean of the First Hospital of Zhejiang Medical University and an academician of the Chinese Academy of Engineering, operated the robot's four robotic arms to remove pancreatic tumors for a 60-year-old patient and took less than 2 hours.

At the beginning of the operation, the doctor first hit 4 small holes of soybean size in the patient's abdomen, and the robot's 3mm arm with a thickness of 8mm and a lens arm protruded into the patient from the small hole. At the operating platform on the other side of the operating room, the surgeon can see a three-dimensional image of the patient's abdominal cavity magnified 20 times. This high-resolution stereogram shows the patient's condition in real time. This field of vision cannot be obtained with ordinary surgery or endoscopic surgery.

The doctor manipulated the joystick back and forth and left and right, and the robotic arm began to look for the location of the tumor in the abdominal cavity of the patient. He ably cut out the tumor deeply buried under the fat and removed it. During this process, the vibration of the surgeon’s hands was completely filtered out, which translated into a robust and precise robotic arm action, which greatly improved the surgical precision and the surgical quality.

The robot's robot arm is equipped with a multi-functional medical tool that can rotate 360 ​​degrees to complete penetration, cutting, electric burning, knotting and other actions, even more flexible than human fingers. "For example, this scissors can condense blood while cutting the blood vessels, so the patient can bleed very little." The chief surgeon sits in front of the operating table and moves his hands to complete most of the work of a past laparoscopic surgery team. Three-quarters of manpower. After removal of the tumor, the robotic arm can also use a needle thread to suture the wound.

Zheng Shusen said that the use of "Da Vinci" robots to achieve a small wound and rapid recovery of patients can greatly shorten the postoperative hospital stay. Robots can be used in urology, gynecology, and other operations to show their skills. For example, in the small pelvis area, not only the space is small, but also a large number of sensitive nerve beams pass through. The operation of the human hand is extremely inconvenient, and the robot arm operates freely. It is understood that 85% of acute prostate surgery in the United States is currently completed by this robotic system.

What's even more exciting for medical workers is that the "Da Vinci" robot system uses "far-reaching" technology. As long as the network transmission rate is guaranteed, in the near future, doctors will be able to direct this station in the office of Hangzhou. Robots perform surgery on patients in remote areas.

According to reports, the "Da Vinci" surgical robot was developed by NASA and other institutions and is currently the most advanced minimally invasive surgical system. Since its introduction into clinical use in 2000, there have been more than 2,000 "Da Vinci" robots serving patients worldwide. By the end of last year, a total of 14 ** use "Da Vinci" robots in China, a total of 18 units.
