Patent ID: 7892167

Claim:
An endoscopy system comprising: a cannula housing an endoscope, an irrigation channel and an outflow channel formed respectively between the cannula and the endoscope, said irrigation channel and outflow channels being intended for transporting an irrigation fluid and outflow fluid, respectively, a coupling ring mounted around the cannula and provided with an irrigation coupling path in fluid communication with the irrigation channel and an outflow coupling path in fluid communication with the outflow channel, respectively, a connector mounted on the coupling ring and comprising an irrigation communication path in fluid communication with the irrigation coupling path and an outflow communication path in fluid communication with the outflow coupling path, respectively, wherein the connector comprises a first pressure sensor facing the irrigation communication path and the outflow communication path, respectively, for sensing the pressure in the irrigation and outflow communication paths, respectively, and wherein the coupling ring comprises a branch-off path in fluid communication with the irrigation channel and with the outflow channel, respectively, wherein the connector comprises a blind path in fluid communication with the branch-off path, and wherein the connector comprises a second pressure sensor facing the blind path for sensing the pressure in this blind path.
