Abstract

In laparoscopic surgeries, CO2 insufflation through a trocar system is required to fill the abdominal or pelvic cavity and provide a working space for the surgeon. The problem arises from the heat loss from the CO2 gas to the surroundings of the trocar since it results in a temperature difference between the entering CO2 and the temperature of the patient’s body, which results in fog formation on the camera lens, blocking the surgeon’s vision. This heat loss occurs by convection between the flowing fluid inside and outside the trocar and by conduction through the trocar’s cannula. The primary objective of this research is to investigate the heat loss of CO2 through the trocar cannula for different materials. These materials should meet specific requirements in order to be used in such surgery. The requirements are biocompatibility, transparency, eco-friendliness, and solid state. The selected materials are PET, PVDF, PEI, PEEK, and PC. Heat transfer and finite element analysis case studies were investigated to observe internal fluid flow behavior for velocity profile and temperature distribution. Then, a model was created and simulated on ANSYS workbench using proper boundary conditions that match real-life conditions. Comparative studies were done using ANSYS for the velocity profile, mean temperature distribution, axial temperature distribution, and radial temperature distribution of CO2. The simulated results showed that PVDF was the best material to be used in the composition of the trocar’s cannula since it resisted the most heat transfer, followed by PC, PET, PEEK, and PEI, respectively.
