Abstract
An apparatus which transmits a laser beam to a target, such as an area of human tissue being treated. Delivery of the beam and its direction to the target area is controlled safely. The apparatus is operatively connected directly to an instrument, such as an endoscope or laryngoscope, which identifies and defines the target area. A joy-stick assembly provides control of the direction of the beam as it enters atmosphere from the apparatus, by manipulation of its lever which swivels its mirror from which the beam is reflected towards the target area. Means to block transmission of the beam from the apparatus to atmosphere is coupled with a fail-safe arrangement of elements whereby only when the mirror is in a proper swivelling position to reflect the beam to the target area is the beam emitted from the apparatus. An adjustable sliding lens system within the apparatus provides change of focus of the beam to effect a change in the plane of treating the target area.
