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. A unique means (22) to universally mount and rotate device (10) to adaptor (20) is provided, with clamping means (23) to stationarily position or lock one to the other at any angle or inclination. Features, such as a nozzle (25) to introduce nitrogen into the chamber (12) to cool the lens (26), scalloped edges (…
