  • Patent number: 5203780
    Abstract: An apparatus and method for venting off a surgical laser smoke plume which is generated when body tissue is treated by an optical fiber lasering device, comprising an elongated hollow needle through which an optical fiber laser member extends for emitting a laser beam at the tip of the needle which is adjacent to the body tissue to be treated. A vent side arm has one end which is attached to the needle, and another end which is connected to a suction device, so that when body tissue is treated by the laser beam emitted at the needle tip, the resulting smoke plume that is created will be suctioned up into the channel between the optical fiber strand and the inner surface of the needle and out the vent side arm into the suction device. An O-ring is attached at the outer end of the needle so that any surgical laser smoke plume that is being suctioned out does not escape into the atmosphere or back to the laser generator, but also goes out the vent side arm and into the suction device.
