Systems and methods for conducting smoke evacuation during laparoscopic surgical procedures

An insufflation and smoke evacuation system for use during laparoscopic surgical procedures, comprising:

• a) an insufflation source;
• b) a pump for circulating pressurized gas within the system, the pump having a supply side and a suction side;
• c) a tri-lumen cannula having a proximal housing defining an inner bowl area and a longitudinal conduit extending distally from an exit at a distal end of the proximal housing, the proximal housing communicating with the insufflation source by way of an insufflation gas supply line and with the supply side of the pump by way of a pressurized gas supply line;
• and
• d) a single lumen cannula communicating with the suction side of the pump by way of a vacuum line, wherein a communication line extends between the inner bowl area of the tri-lumen cannula and the vacuum line, such that the proximal housing of the tri-lumen cannula has a first gas inflow path, a second gas inflow path, and a gas outflow path, wherein the first gas inflow path is associated with the insufflation gas supply line, the second gas inflow path is associated with the pressurized gas supply line and the gas outflow path is associated with the communication line that extends between the inner bowl area of the tri-lumen cannula and the vacuum line, wherein the gas outflow path extends radially from the proximal housing and is separate and distinct from the exit at the distal end of the proximal housing, and wherein the longitudinal conduit of the tri-lumen cannula is configured to be used as an access port for a laparoscope during laparoscopic surgical procedures, and the tri-lumen cannula and the single lumen cannula are configured to be arranged within an abdominal cavity such that when smoke is generated within the abdominal cavity during a laparoscopic surgical procedure, the smoke will exit the abdominal cavity through the single lumen cannula in an area located away from a distal end of the laparoscope so as not to impact visibility through the laparoscope.
