Abstract: Laparoscopic procedure used by surgeons comes under minimally invasive surgery to operate upon the abdominal cavity. The CO2 insufflator process is used to insufflate the abdominal cavity to enable safe and efficient surgical intervention. In most surgeries, the CO2 insufflator are repeatedly pumped into abdominal region to maintain intra-abdominal pressure due to various instrument exchange resulting in leakage. The improved forceps is a combination of a suction-irrigator, CO2 insufflator, and a dissector forceps. A more comprehensive CFD flow of CO2 gas, is numerically simulated in the present work for different driving mass flow rates. The results are investigated with the help of simulated contours. The new surgical forceps eliminates re-insertion of CO2 insufflator, dissector, and suction-irrigator by making multi-functional, can be reusable, non-toxic, corrosion-resistant, toughened, and cost-effective.
