Method and apparatus for laser induced thermo-acoustical streaming of liquid

摘要

A laser induced thermo-acoustical system has a waveguide for propagating laser radiation to an absorbing layer of a tip. The tip has an absorbing layer serving to absorb the laser radiation propagating through the waveguide. The absorbing layer has such an absorption coefficient that upon absorbing the laser radiation the absorbing layer heats up to boil a quantity of a liquid when the tip is surrounded by the liquid. A laser induced thermo-acoustical method calls for providing a waveguide for propagating laser radiation to the absorbing layer of the tip to be at least partially absorbed by the absorbing layer and to boil a quantity of the liquid surrounding the tip and generating the stream of liquid. The laser induced thermo-acoustical streaming of the liquid is used, in particular, for the treatment of a root canal and periodontal pockets.
