Gas recirculation system and method

A medical system for use in an endoscopic surgical procedure, the system comprising:

• an insufflator configured to provide gas to a peritoneal cavity;
• an insufflation tube in fluid communication with the insufflator, wherein the insufflation tube is configured to be connectable to surgical equipment that is insertable into a peritoneal cavity;
• a gas recirculation system comprising:
• a pump comprising:
• a motor;
• and
• a pump cartridge coupled to the motor, wherein the pump cartridge includes a gas input connection and a gas output connection, wherein the pump cartridge is detachable from the motor, and wherein the pump cartridge is sealed such that a gas within the pump cartridge cannot contact the motor;
• a first tube in fluid communication with the gas input connection, wherein the first tube is configured to be connectable to surgical equipment that is insertable into a peritoneal cavity;
• and
• a second tube in fluid communication with the gas output connection, wherein the second tube is configured to be connectable to surgical equipment that is insertable into a peritoneal cavity;
• wherein the pump is configured to draw gas into the gas input connection from a peritoneal cavity through the first tube and to discharge gas out of the gas output connection and into a peritoneal cavity through the second tube;
• wherein the insufflator and the gas recirculation system are configured to recirculate gas from the peritoneal cavity and to maintain a pressure within the peritoneal cavity.
