A nozzle device (1) comprises a plurality of multi-fluid nozzles (5) and a body (2) with a bore (8). The bore (8) has a laser entrance (82) and a laser exit (81). The nozzle device (1) is adapted to be mounted to a laser medical device such that a laser beam generated by the laser medical device enters the laser entrance (82) of the bore (8) of the body (2) and exits the laser exit (81) of the bore (8) of the body (2). The body (2) houses the multi-fluid nozzles (5) and the multi-fluid nozzles (5) are arranged around the laser exit (81) of the bore (8) of the body (2). The nozzle device (1) allows to conditioning a tissue at and near where it is cut or drilled by the laser beam of the laser medical device. Thus, the nozzle device (1) is particularly suitable for a laser osteotomic device allowing to minimize collateral damages of the tissue when being cut or drilled.
