A nozzle device () comprises a plurality of multi-fluid nozzles () and a body () with a bore (). The bore () has a laser entrance () and a laser exit (). The nozzle device () 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 () of the bore () of the body () and exits the laser exit () of the bore () of the body (). The body () houses the multi-fluid nozzles () and the multi-fluid nozzles () are arranged around the laser exit () of the bore () of the body (). The nozzle device () 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 () is particularly suitable for a laser osteotomic device allowing to minimize collateral damages of the tissue when being cut or drilled.

Conditioning a laser-tissue contact surface

A photoablation device includes a laser source to propagate a focused laser beam with a beam waist, wherein a radius of the beam increases from the waist in a direction of propagation of the beam; an adjusting structure to adjust an intensity of the beam; a position detector to detect a position of the source in relation to the tissue; a positioning device to move the source in relation to the tissue; and a controller. The controller is to define a photoablation zone of the beam, wherein the zone ends in a cutting face located offset from the waist in the direction of propagation; adjust the intensity of the beam at the face of the zone using the adjusting structure; and move the beam towards the tissue by using the positioning device, wherein the position of the source detected by the position detector is evaluated.
