Abstract:
1. A laser device comprising at least one laser energy source generating a laser beam: a housing from which the laser beam emits; a support structure attached to the housing such that a patient can be scanned by the laser beam without moving the housing; and a scanning head connected to the housing that directs the laser beam into any location forward of the scanning head, wherein the scanning head comprises: a) a reciprocating pushrod having a tapered leading edge and aligned along a central axis; b) a main drive gear aligned along the central axis and through which the pushrod extends; c) a rocker carriage aligned along the central axis, positioned to cooperate with the leading edge of the pushrod, and connected to the main drive gear such that the rocker carriage rotates as the main drive gear rotates, wherein the rocker carriage comprises a transverse axle, an optical element rotatably attached to a transverse axle, and a spring clip biasing the optical element against the leading edge of the pushrod; d) a beveled cam abutting the pushrod, the beveled cam driven by a second drive motor to cause the pushrod to reciprocate and thereby rotate the optical element about the transverse axle; and e) a minor drive gear mated to the main drive gear and driven by a first drive motor to cause the main drive gear and attached rocker carriage to rotate about the central axis.
