    Patent number: 4185633
    Abstract: Biological tissue is dissected by means of a mechanical cutting instrument, while the coagulation of the walls of the incision is effected simultaneously with the dissection by means of a laser beam, for which a laser beam spot is formed in the immediate proximity to the cutting instrument's cutting edge. An apparatus for the realization of this method combines a mechanical cutting instrument made preferably of a material transparent to laser emission, and a structure for the formation of a laser beam spot in the immediate proximity to the cutting instrument's cutting edge. In the preferred embodiment the cutting instrument itself provides for the formation of the spot close to the cutting edge.
