ABSTRACT
OBJECTIVES@#Surgical robot system has broken the limitation of traditional surgery and shown excellent performance in surgery, and has been widely used in minimally invasive treatment in most areas of surgery. This study aims to verify the basic performance of the domestic surgical robot system and the safety and effectiveness of the integrated bipolar electrocoagulation and ultrasonic knife.@*METHODS@#The basic performance of the domestic surgical robot system was evaluated by completing the square knot and surgical knot, vertical and horizontal perforation and right ring perforation and suture, as well as picking up beans. Compared with laparoscopy, the safety and effectiveness of the domestic surgical robot after integrated interconnection bipolar electrocoagulation and ultrasonic scalpel were evaluated by detecting the vascular closure performance and the degree of histopathological damage in animals.@*RESULTS@#Compared with freehand knotting, domestic robot knotting speed and circumference were slightly worse, but better than laparoscopic knotting. There was no statistical significance in the tension difference of the surgical knots among the 3 methods (P>0.05), but the tension of the square knots made by the freehand and the domestic surgical robot was greater than that of the laparoscopy (P<0.05). The space required for both the left and right forceps heads of knots was smaller than that of laparoscopy (P<0.001), which successfully completed the 4 quadrant suture tasks, and the time of picking up beans was significantly less than that of laparoscopy (P<0.05). There was no significant difference in the temperature of the liver tissue after the bipolar electrocoagulation between the interconnected domestic surgical robot and the laparoscopy (P>0.05), and the acute thermal injury was observed under the light microscope. The temperature of the liver tissue treated by the domestic robotic ultrasound knife was higher than that of the laparoscopic ultrasound knife (P<0.05).@*CONCLUSIONS@#Domestic surgical robots are obviously superior to laparoscopy in suturing, knotting, and moving objects, and domestic surgical robots' interconnect bipolar electrocoagulation and ultrasonic knife have achieved success in animal experiments, and hemostasis is considered to be safe and effective.
