An endoscope lens cleaning apparatus used for removing surgical debris from an objective lens of an endoscope. The endoscope lens cleaning apparatus includes an elongated sheath and a connection assembly. The elongated sheath includes an endoscope lumen and an irrigation channel, configured in parallel and adjoining, each extending between an inlet end and an outlet end. At least one stand-off is formed within the elongated sheath along the outlet end. The endoscope lumen and the irrigation channel are fluidly open to one another when the endoscope lumen is in an empty state and the irrigation channel is fluidly sealed from the endoscope lumen between the at least one stand-off and the inlet end when the endoscope lumen is in an occupied state. A fluid passageway extends from a fluid port of the connection assembly and is configured to align and fluidly connected with the irrigation channel.
