Objective To study the training effect of virtual simulation laparoscopic training system on the basic skills of endoscopic sinus surgery for practitioners with different clinical experiences. Methods A retrospective study was carried out by the training group of visiting surgeon

the hospitalized standardized training physician group and the five-year clinical undergraduate internist group. The laparoscopic training box and the virtual simulation laparoscopic training system were used to carry out microscopic examination of the grab items

ferrule

object transfer

Instrumental knotting and coagulation techniques

training 30 minutes a day for a total of 4 weeks

compared before and after training between the various groups and scores. Results Before the training

clinical undergraduate interns

grab items

ferrule

object transport

cut gauze

suture

instrument knotting and electrocoagulation compared with the clinical training of physicians and visiting surgeons have significant difference (P<0.05)

after 4 weeks of training

each participant training score in the training time and were higher than that before training (P<0.05). Simple skill operation such as grab items

ferrule

object transfer

cut gauze between each group no statistical difference (P＞0.05); complex skill operation suture

appliance knot and electro coagulation technology in the standardized training of doctors

clinical undergraduate interns group score better than visiting surgeons

there was statistically significant difference (P<0.05). Conclusion Virtual simulation of laparoscopic training system can improve the clinical skills of laparoscopic surgery for different levels of clinical training

it is worth popularizing in clinical teaching at all levels.
