After the power-on ceremony, Professor Xu Shidong, director of the First Ward of Thoracic Surgery, Cancer Hospital affiliated to Harbin Medical University, performed lung tumor resection for a patient with Da Vinci robot.
Mr. Liu, 57, accidentally found a nodule of 14 mm on his right lung during physical examination. After examination, it was diagnosed as an early lung tumor and needed surgery. "I just heard that the hospital introduced surgical robots, but I was lucky to be the first beneficiary," Mr. Liu said happily.
During the operation, Professor Xu Shidong only opened three keyhole-sized surgical holes and 1 3 cm auxiliary surgical holes in the patient's chest, and put the robot's arm into the chest. The three-dimensional image of the human chest formed by the camera is enlarged 10- 15 times. Professor Xu sits on the console and operates through the joystick, using a robot operating instrument that is more flexible than the wrist.
According to Professor Xu Shidong, Leonardo da Vinci's robotic surgery system integrates many high technologies. Surgeons no longer operate surgical instruments in person, but observe and control the three-dimensional endoscopic surgery picture on the console far away from the operating table. The system converts the techniques and methods operated by doctors into data information, which is transmitted to the manipulator after processing, and then the manipulator operates according to the instructions.
"Simply put, it is the surgeon's surgical thinking and specific operations, which are completed by robots." Professor Xu Shidong introduced. The robot has four mechanical arms, and the robot hand can run flexibly in a space of 540 degrees, which is three times the range of the human hand, especially in a narrow anatomical area. Moreover, the surgical robot system has a stabilizer, which can automatically filter out the jitter of human hands, avoid the accident of scratching nerves and blood vessels due to hand jitter during surgery, make the operation safer and more thorough, and break through the limitations of human hands.
The lens arm of the robot has a built-in 3D camera, which can enter the human body, display the real three-dimensional structure in the body, and enlarge the surgical field of vision by 10- 15 times, breaking through the limitation of human eyes. Compared with traditional surgery, robot surgery can achieve accurate minimally invasive, less trauma, small incision, less intraoperative bleeding, and reduce postoperative infections and complications.
According to reports, the Cancer Hospital affiliated to Harbin Medical University introduced the first fourth-generation Da Vinci surgical robot in China. Not only can two surgeons exchange control instruments and communicate during the operation, but also experienced da Vinci surgeons can simulate synchronous tape to teach novice doctors.
According to Qu Guofan, president of the Cancer Hospital of Harbin Medical University, the hospital will organize professional backbones to go abroad for training, popularize robotic surgery in thoracic surgery, gastrointestinal surgery, gynecology, urology and other fields, so as to benefit more patients and gradually build a regional and even national robotic surgery training platform and teaching demonstration center.
