An animal experimental study on domestic robot-assisted microvasectomy for laparoscopic surgery
To explore the feasibility, effectiveness and safety of domestic endoscopic surgical robot system for vasectomy. METHODS: Twelve healthy SD male rats aged 3-4 months and weighing 350-450 g were selected and randomly assigned to the experimental group and the control group according to their weight compatibility by random number method, with 6 rats in each group. Robot-assisted technology was used in the experimental group, and vas deferens anastomosis was performed in the control group by microscope technology. The anastomotic operation time, intraoperative adverse events (broken thread, bent needle), and operator's operating experience were recorded in the two groups. Results: All operations were successfully completed, and the postoperative anastomotic patency rates in both groups were 100%. The experimental group needs to be connected, the operation time is longer, and the incidence of bent needles and broken lines during the operation is higher, but the postoperative evaluation of the operation experience by the operators is better than that of the control group. Conclusion: The domestic endoscopic surgical robot-assisted vasectomy anastomosis is safe, feasible and effective, and can significantly reduce the fatigue of traditional microsurgery.
