Abstract
An therapeutic laser device that incorporates a scanning head to direct low level laser light into a treatment zone that can have any desired shape or energy distribution within a hemisphere forward of the scanning head. The device enables laser light of different pulse widths, different beam shapes and different energy distributions to be applied externally to a patient's body.
Claims2
A laser device comprising:
- a) at least one laser energy source for generating a laser beam;
- b) a wand from which the laser beam emits, the wand being capable of being retained in a hand of a user and freely moved relative to the surface of the skin of a patient;
- and
- c) a scanning head attached to the wand for receiving the laser beam and for directing the laser beam to a desired location wherein the scanning head comprises a spindle mounted for rotation on a hollow shaft, an optical element mounted on the spindle and rotatable in a plane perpendicular to a plane of rotation of the spindle, a cam slidably mounted on the spindle and rotatable with the spindle, and a hinged arm joining the cam to the optical element such that sliding motion of the cam on the spindle causes rotation of the single optical element relative to the spindle.

A therapeutic laser device comprising:
- a) a laser energy source generating a laser beam;
- b) a wand from which the laser beams emit, the wand having an interior cavity and being capable of being retained in the hand of a user and freely moved relative to the surface of the skin of the patient;
- c) a scanning head mounted in the interior cavity of the wand for receiving the laser beam and for directing the laser beam into a desired location, the scanning head comprising a spindle mounted for rotation on a hollow shaft, an optical element mounted on the spindle and rotatable in a plane perpendicular to the plane of rotation with the spindle, a cam slidably mounted on the spindle and rotatable with the spindle, and a hinged arm joining the cam to the optical element such that sliding motion of the cam on the spindle causes rotation of the optical element relative to the spindle;
- and
- d) a control circuit for controlling the scanning head to direct the laser beam to form a desired shape.
