From Sushuruta, the sage of the Ganges Valley, to Hippocrates, the Greek healer, the scalpel has been a faithful companion accompanying the surgeon, a sharp tool to relieve pain and a staff to destroy disease. More than 2,500 years later, has the scalpel fallen out of fashion? The scalpel in the traditional sense can be considered a product of the Cold War era, with thin, sharp blades that have become more resilient and sharper with advances in metallurgy. What’s more, the modern “electric knife” in the role of electricity not only has the role of cutting separation, but also has the role of hemostasis. However, the advent of the industrial and electrical age has changed the surgeon’s traditional cold-weapon era surgical approach. The traditional surgical approach has gradually been replaced by the minimally invasive surgical approach represented by lumpectomy, which is gaining popularity. The lumpectomy and lumpectomy instruments can be seen as a continuation of the surgeon’s eyes and hands, helping the surgeon to reduce unnecessary trauma to the patient while relieving the patient’s ailment. But technology goes beyond that. On July 11, 2000, the U.S. Food and Drug Administration (FDA) approved the da Vinci Surgical System, making it the first robotic system available for use in the operating room in the U.S. The advent of the age of intelligence is quietly affecting the way we operate. If lumpectomy and lumpectomy instruments are a continuation of the surgeon’s eye and a continuation of the hand, the da Vinci Surgical System is not only a continuation, but an enhancement of the surgeon’s eye (optical magnification of ten times the stereoscopic clear image) and an enhancement of the hand (7 degrees of freedom with a far greater range of motion than the human hand). This change has opened up a new concept of surgery – precision surgery. While traditional surgical methods are being replaced by minimally invasive surgical methods in more and more hospitals, precision surgery has come to us. We have successfully used the da Vinci Surgical System to perform precision surgery for lung cancer, precision surgery for esophageal cancer, precision surgery for mediastinal tumors, and more. The clear stereoscopic field of view allows us to identify finer blood vessels and nerves to reduce bleeding and injury, and the highly free robotic hand allows us to separate, cut and suture more carefully to improve the precision of surgical resection.
