An endoscopic system and method for its operation are disclosed. The system comprises a light source, an endoscope with a distal light entrance surface, an image sensor capturing images through the light entrance surface and a rinsing device for providing a rinsing fluid flow for rinsing the light entrance surface, the method including the steps of receiving a sensor signal from a sensor detecting a user input starting a rinsing operation of the rinsing device, and, upon receipt of the sensor signal, changing an illumination mode of the light source from a first illumination mode to a second illumination mode and/or changing the video capture from a first video capture mode to a second video capture mode. The second illumination and/or video capture mask undesirable visual artifacts which can occur when collecting images with a rolling shutter sensors while performing a liquid flush of the light entrance surface.

Endoscope and endoscopic system

Endoscope, endoscopic system and method of operating the endoscopic system

A vent assembly configured to maintain predetermined positive and negative pressure differentials between gas within a compartment and the environment, such as a compartment defining an interior of an endoscope is provided. The vent assembly includes a first housing having an upper vent and a lower vent coupled to the compartment. A piston is movable from a closed position to a first position, and from the closed position to a second position. In the closed position the piston blocks the upper and lower vents. A positive pressure differential moves the piston so as to open the vent to allow gas to escape from the compartment. A negative pressure differential draws the piston from the closed position to a second position to allow gas to enter the compartment.

Vent assembly

A pressure control and leak test system for a medical instrument includes an upper housing, a valve member, and a vent opening arrangement. The upper housing includes a cavity for fluid communication with an interior of the medical instrument and an aperture in fluid communication with the cavity. The valve member includes a stem within the aperture and a cap section. The cap section includes a proximal-facing end with a bottom surface and a distal-facing end. The vent opening arrangement includes a first feature of the cap section and a second feature on the distal end of the upper housing. The valve member rotates relative to the housing causing the first feature and the second feature to seal the cap section with the housing in a first position and separate the cap section from the housing in a second position.

Pressure relief vent for sealed instruments

A pressure relief vent includes a vent enclosure, a connector, and a pressure relief arrangement. The vent enclosure defines a vent interior volume and the connector is operable to connect the vent enclosure to an instrument requiring pressure relief. The vent enclosure has a proximal end and a distal end, with the connector being located at the proximal end. The pressure relief arrangement is operable to remain in a closed condition in normal operation, but move from the closed condition to an open condition in response to a predefined pressure differential so as to release pressure from the instrument. A vent opening device may be included with the pressure relief vent and is operable to move the pressure relief arrangement to the open condition or open a separate passage through the vent enclosure to the atmosphere responsive to a manual operation applied at the vent enclosure distal end.
