Also provided is a method for producing a spray cone (58) of a medical irrigation liquid (18), in particular using a spraying device according to one of Claims 1 to 16, in which the irrigation liquid (18) is pushed through a plurality of openings in a nozzle (24, 52) and the irrigation liquid jets thus produced are shot towards one another at such a flow rate and at such an angle that the irrigation liquid jets atomise in front of the nozzle (24, 52) and form a spray cone (58).1/2 38 36 34 30 26 9 15 14 12 10 9 8 1 2 4 6 24 3 2 2 2 922 18 9 Figure 1
