1. An endoscope comprising: a tip part, the tip part including:
a housing having a proximal end, a front end opposite the proximal end, a circumferential wall extending from the front end to the proximal end, a front wall, and a nozzle, the circumferential wall and the front wall defining an interior spacing of the housing;
a vision sensor positioned in the housing; and
a camera window positioned at the front end of the housing;
wherein the housing further comprises, extending proximally from a proximal surface of the front wall, a gas channel and a liquid channel, the gas channel sized and shaped to receive a distal end of a gas tube and the liquid channel sized and shaped to receive a distal end of a liquid tube,
wherein the nozzle comprises a nozzle roof positioned distally of the gas channel and the liquid channel, the nozzle roof defining a nozzle outlet,
wherein the gas channel, the liquid channel, the nozzle outlet and the camera window are aligned such that a plane parallel to a longitudinal dimension of the distal tip traverses the gas channel, the liquid channel, the nozzle outlet and the camera window, and
wherein the nozzle roof is sized and shaped to cause a gas and a liquid discharged through the distal ends of the gas tube and the liquid tube to impinge on, and be redirected by, the nozzle roof through the nozzle outlet toward the camera window along the plane.
