Claim:
1. An endoscope lens cleaning apparatus for removing surgical debris from an objective lens of an endoscope, comprising: an elongated sheath including an endoscope lumen and an irrigation channel, each extending between an inlet end and an outlet end opposite the inlet end of the elongated sheath, wherein the outlet end defines a distal end of the endoscope lens cleaning apparatus, wherein at least one stand-off is formed within the elongated sheath along the outlet end, wherein the irrigation channel is configured parallel and adjoining to the endoscope lumen, wherein the irrigation channel is non-coaxial to the endoscope lumen, wherein the endoscope lumen and the irrigation channel are fluidly open to one another when the endoscope lumen is in an empty state, and wherein 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; and a connection assembly including a manifold housing forming a coupling port, an access port, and a fluid port, wherein the coupling port is configured to mate with the inlet end of the elongated sheath, and wherein the access port defines a proximal end of the endoscope lens cleaning apparatus, wherein an interior surface of the access port includes circumferential ridges configured to fluidly and frictionally seal against an endoscope insertion body of the endoscope; wherein an endoscope passageway extends between the coupling port and the access port and is configured to matingly axially align with the endoscope lumen of the elongated sheath when mated, wherein the endoscope passageway and endoscope lumen have a substantially equivalent diameter between the distal and proximal ends of the endoscope lens cleaning apparatus, wherein the proximal end is configured to terminate along the endoscope insertion body of the endoscope independent of a non-insertion portion of the endoscope, wherein a fluid passageway extends from the fluid port and includes a channel portion that is configured to matingly axially align and fluidly connect with the irrigation channel, and wherein the endoscope passageway and the fluid passageway are fluidly open to one another in the empty state and fluidly sealed from one another in the occupied state.
