Abstract
A phototherapy device has a phototherapy handpiece, an optical fiber attached to the phototherapy handpiece, and a laser phototherapy light source. The phototherapy handpiece, has a handpiece body that defines an interior region and has an outer surface which defines a foot of the phototherapy handpiece, an optical fiber drive assembly disposed at least partially within the interior region of the handpiece body has an optical fiber attachment portion that is movable relative to the handpiece body. The optical fiber drive assembly includes a driving component which causes the attachment portion to move relative to the handpiece body, and a damping component which resists the motion of the optical fiber attachment portion such that the optical fiber attachment portion attains a substantially constant speed motion relative to the handpiece body.
