A trocar system, having a trocar, an optical channel extending coaxially in the trocar for receiving an optical unit, and a hollow transparent distal tip of the trocar, which can be observed from the interior by means of the optical unit, wherein at least one working channel is constructed in the wall of the trocar surrounding the optical channel, which channel extends continuously and axially parallel from the proximal end of the trocar into the distal tip and opens into an outlet opening in the region of the tip.
