<p>A surgical instrument (1) utilizing a laser beam is frequently used to obtain an incision (15) through gasification or vaporisation. This gasification and vaporisation is usually extremely injurious to the person operating the instrument (1). The object of the present invention is to draw off as much of said vaporisation and gasification as possible. In practise this is achieved by providing the radiation end (3) of the instrument (1) with a conical sleeve (7) connected to a suction arrangement (11-13) so that the beam is surrounded from the centre and outwards by a suction effect.</p> |
