  • Gas recirculation system and method
    Patent number: 11583641
    Abstract: Gas recirculation systems for use in endoscopic surgical procedures including a gas recirculation pump are disclosed. The gas recirculation pump may work in conjunction with an insufflator used to inflate a patient's peritoneal cavity during surgery. The gas recirculation system may recirculate a high flow rate of gas from and to the patient while filtering particulate matter out of the gas and while maintaining an adequate moisture content in the gas. The gas recirculation pump may include a disposable pump cartridge releasably connected to a pump motor. A controller may detect a fault or safety condition in the gas recirculation system based on the load placed on the pump motor.
    Type: Grant
    Filed: October 14, 2019
    Date of Patent: February 21, 2023
    Assignee: NORTHGATE TECHNOLOGIES INC.
