On June 3, 2020, the first da Vinci robot weight reduction surgery in Guangdong was successfully completed in our hospital, which plays a significant role in the development of surgery. “Is the surgery safe?” The safety of bariatric surgery has always been a key concern for many consultants, and at the same time the medical community has been dedicated to the technical research of surgery, in order to make it safer and more efficient. Among them, the advent of the da Vinci robot has brought surgery to a new level. The medical world has entered a new minimally invasive era. In traditional surgery, the surgeon must hold the instruments himself and do the surgery beside the patient, which requires a high degree of concentration throughout the entire procedure and leads to physical and mental exhaustion after one surgery. This is why we always emphasize the experience and skill of the lead surgeon, as these factors are directly linked to the safety of the surgery and the incidence of post-operative complications. In contrast, the addition of the da Vinci robot allows the operating surgeon to leave the operating table and simply go above a console to control the robot arm to complete the entire surgical procedure. What are the advantages of da Vinci robotic surgery? 1. Clearer imaging Compared with most traditional laparoscopes, which have a two-dimensional visual lens with small magnification, the da Vinci robot’s “eye” has a high-resolution three-dimensional visual lens with 10 times magnification. In bariatric surgery, it not only enables the surgeon to observe the abdominal cavity and stomach structure more clearly, but also greatly improves the precision of the surgical process, such as the judgment of the cutting edge and fine operations like suturing and knotting.2. The da Vinci robotic surgeon’s console allows for more flexible separation and suturing of the stomach and intestines in a small abdominal space during bariatric surgery, making it easier to perform complex surgical maneuvers that are difficult to perform with traditional laparoscopic bariatric instruments. 3. operations. The control handle filters out subtle tremors in the surgeon’s hand, increasing the stability of the operation, making it more delicate and safer than traditional laparoscopic bariatric surgery, and helping to perform complex surgical maneuvers that are difficult to perform with traditional laparoscopic surgical instruments. Although the da Vinci robot has the advantages of low bleeding, inconspicuous trauma port, fast post-operative recovery and high surgical safety, the premise is that the main surgeon is required to operate it, so the key to bringing out the advantages of the da Vinci robot also lies in whether the main surgeon’s skills and experience are good enough. Compared with traditional surgery, doctors will be uncomfortable when they first start. However, with the increase in the number of surgeries and the accumulation of practical experience, the surgeon can control and correct the jitter caused by the surgeon’s excessive auxiliary movements in real time, and reduce the operating errors, which requires a very high degree of operating skills.
