An endoscopic instrument is provided comprising a shaft having an endoscope optical system arranged therein, which has a distal front face. The instrument also comprises a working element arranged in the shaft. The shaft provides for the supply of an irrigation fluid. Flow-influencing means are provided, such that the irrigation fluid reaches in front of the front face of the endoscope optical system and can eliminate contaminations, which obstruct the view through the endoscope optics.
