The tissue thermal effect of electrosurgical unit (ESU) can cause eschar on the surface of pancreatic tissue, which has the effect of hemostasis and preventing pancreatic fistula. The electro-mechanical parameters of ESU have a significant effect on the function of eschar hemostasis and preventing pancreatic fistula, but there is still a lack of in-depth study on the law of its action. In this study, three key electro-mechanical parameters, i.e. power, acting time and diameter of electrode front end, were studied in the DESICCATE mode by using in vitro simulation test method, combined with burst pressure test of pancreatic duct and eschar morphology analysis. Based on the above, the interaction between power, acting time and diameter of electrode front end was obtained by response surface analysis and the electro-mechanical parameters with the best effect of pancreatic duct sealing. The results show that the burst pressure of the pancreatic duct is at the peak value when the power is 60 W, the burst pressure of the pancreatic duct is at the peak value when the acting time is 2.00 s, and the burst pressure of the pancreatic duct is at the peak value when the diameter of the front end of the electrode is 2.00 mm. The best electro-mechanical parameters in the DESICCATE mode are: the power of electric knife is 59.39 W, the action time is 2.18 s, and the diameter of electrode front end is 2.31 mm. In addition, the diameter of the electrode front end is an independent factor affecting the pancreatic duct sealing effect, the power and acting time of the ESU have significant synergistic effect on the pancreatic duct sealing.
