  • Laser scalpel
    Publication number: 20020128637
    Abstract: A laser scalpel for cutting biological tissue. The laser scalpel includes a suctioning device with a suction channel which is arranged parallel to a laser fiber. The suction channel protrudes beyond the end of the laser fiber, and the protruding portion of the suction channel includes a suction opening in the wall of the suction channel facing the laser beam. The suction opening is thus oriented towards the laser beam which exits from the distal end of the laser fiber. This prevents the suction channel from becoming blocked.
