Abstract
A system for facilitating insufflation and recirculation of fluid during a laparoscopic surgical procedure that includes a trocar, an insufflator for delivering insufflation fluid to the abdominal cavity of a patient through the trocar, a pump for delivering pressurized fluid to a supply plenum of the trocar through a supply line to create a fluid seal within the trocar and for receiving spent fluid from a return plenum of the trocar through a return line, a bypass line for connecting the supply line to the return line under certain pressure conditions, a back pressure control valve positioned within the bypass line and a dump valve in communication with the supply line for releasing pressurized fluid out of the system when an over-pressure condition is sensed.
