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.
