1. A device for irrigation and/or insufflation during endoscopic surgery or endoscopic procedures in a body cavity, comprisinga first fluid pump device in fluid connection with the body cavity via a fluid line, wherein the first fluid pump device is adapted to deliver a fluid to the body cavity,a second fluid pump device in fluid connection with the body cavity via a fluid line, wherein the second fluid pump device is adapted to move a fluid from the body cavity,a control unit connected to the first fluid pump device and/or the second fluid pump device,a blood pressure measuring device, connected to the control unit, wherein the blood pressure measuring device is adapted to measure a blood pressure, and deliver a blood pressure measurement signal,wherein the control unit is adapted to derive a control signal based on the signal from the blood pressure measuring device, wherein the control unit is further adapted to send the control signal to the first fluid pump device and/or the second fluid pump device,wherein the control signal is derived by processing the signal from the blood pressure measuring device by using a correlation factor stored in the device, wherein the correlation factor is dependent on the relationship between the blood pressure measurement signal and a perfusion pressure of the body cavity,wherein the first fluid pump device and/or the second fluid pump device is adapted to control the pressure in the body cavity based on said control signal received from the control unit.
