Abstract:
1. An apparatus for use with a treatment energy source in a dermatological treatment, the apparatus comprising: a handpiece including a handpiece casing; and a pivoting tip connected to the handpiece casing by a pivot axis, the pivoting tip including a planar element with a flat surface and an exit port on the flat surface for the treatment energy, a first roller element coupled with the planar element, and a second roller element coupled with the planar element, the planar element configured to receive treatment energy from the treatment energy source and to deliver the treatment energy from the exit port to a target region of the skin, the pivot axis located between the first roller element and the second roller element, the planar element configured to roll on the first roller element and the second roller element across a surface of the target region of skin, and the planar element configured to pivot relative to the handpiece casing about the pivot axis for adjusting to deviations in handpiece angle with respect to the surface of the target region of skin so that a portion of the pivoting tip maintains contact with the surface of the target region of skin.
