Changsha, April 4 (reporter Yang Xiye) This morning, the Third Xiangya Hospital of Central South University announced in Changsha that the hospital was the first in China to carry out the surgical repair of gastric puncture and appendix surgery in China, which markedChina’smilestones of surgical robots. The independent innovation of a domestic surgical robot has broken the global monopoly of surgical robot technology.
Zhu Sunhong, associate dean of the Third Xiangya Hospital of Central South University, introduced that on March 26th, March 31st and April 2nd, the hospital had performed operations on two male patients and one female patient respectively. One of the men admitted to hospital was diagnosed as gastric perforation with diffuse peritonitis and the other two were appendicitis. After ethical review and informed consent, the hospital underwent "laparoscopic exploration + robot assisted gastric perforation repair" and "laparoscopic exploration + robot assisted appendectomy" under general anesthesia. The patient's condition remained stable after surgery. Two male patients recovered well.
The robotic surgical system is an "endoscopic surgical instrument control system" consisting of a doctor's console, a robotic arm system, and a 3D imaging system. During the operation, the doctor operates on the console and observes the operation. The system transmits the doctor's movement signal to the robot arm through the “remote control” and translates it into a synchronous and real action of the robot in the patient's body to complete the surgery.
Reducing the patient's surgical trauma has always been an important goal of modern medicine. In the 1980s, the application of laparoscopy opened the era of "minimally invasive" surgery. However, laparoscopy has its limitations. For example, the limited angle of rotation of surgical instruments has caused some surgical blind spots and can only be provided surgeons with two-dimensional surgical vision and so on. These factors limit the expansion of laparoscopic techniques to more complex surgical procedures. Surgical robots were born in the early 21st century to advance surgery to the "third generation."
According to experts, compared with the first-generation laparotomy and the second-generation minimally invasive surgery, robotic surgery has more advantages. First, it looks directly at three-dimensional high-definition images, making the surgical vision more clear; second, the simulation wrist has 7 degrees of freedom, which will greatly improve the precision and accuracy of the surgical operation; third, the surgical operator can adopt a sitting posture, which is conducive to complete a long, complicated operation. Surgical robotic surgery will become the new direction of development in the field of minimally invasive surgery and the preferred method for surgical treatment of diseases
