The invention concerns a surgical sprayer for physiological serum, designed to clean the surgical site, comprising a cannula (1) consisting of a passage supplying compressed air and a passage supplying physiological serum to the distal hub (4) serving as spray chamber and provided with an outlet for the resulting mixture, the proximal part of said cannula being connected to the conduits (2A, 3A) supplying air and serum coming from a remote source. The inventive sprayer is essentially characterised in that it comprises a handle (6) incorporating means (7 and 8), with gradual collapse for regulating the flow rates of air and serum and valve-type means (9) acting simultaneously on the air and serum passages so as not to modify the adjustments preset by the surgeon himself, during the surgical procedure. |
