Abstract: An autoclavable laser beam manipulator, made of non-corrosive materials forming its elements which in turn contribute to a novel construction for this instrument that is used with endoscopes of all kinds. Aircraft grade aluminum forms elements such as housing and piston. Laser grade uncoated molybdenum forms the mirrored element mounted on the piston and disposed within a chamber for the housing. Glass-filled DELRON material forms a member which contributes to the adjustment of location and position of the mirrored element to change the direction of laser beam egress from the device, thus controlling such direction.

Abstract: A gimbal assembly mounted in a housing, particularly in a laser beam manipulator, by which the change of direction for a reflected beam or the like is measured in a second of a degree-of-arc in motion. An element such as a specular one including a mirror is mounted within a gimbal ring subassembly, the compound or universal motion of which is actuated by a member such as a shaft that is operatively connected to a swivable member mounted in a structural frame member. Such operative connection provides for the same change in direction for the laser beam as the change of direction of movement for means controlling the swivel element. Or, the actuating member can be fixed to the swivel member by which the element moves in a direction opposite to the direction of movement for the controlling means (joystick). Means are provided to apply pressure to and on the swivel member to thereby ease or make difficult the manipulation of the joystick, depending on the desire of the operator.

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.

Abstract: A device (10) for directionally controlling a beam of light, particularly adaptable with a laser beam in surgical operations. The beam is focused in a chamber (10) by a lense (46) (one of a selectable number), passes through a passageway (16) through which the operator or surgeon observes the target area for the beam, and strikes a specular element or mirror (27) in a cavity (26) separated from the chamber (12) by the passageway (16). The disposition of the mirror (27) in the cavity eliminates vignette obstructions of such element that heretofore was disposed in the passageway in prior teachings. The beam reflects from the mirror (27) in the direction of the target. A unique joystick (28) is operatively connected to the mirror (27) to swivel same and thereby control the direction of the beam. The device (10) is mounted to an adaptor (20) for 360.degree. rotation thereabout.
