APPARATUS FOR AND METHOD OF LASER SURGERY OF HARD TISSUES

摘要

An apparatus (20) for ablating a target site (22) of a hard biological tissu e (24), such as enamel, dentine and bone tissue including a first radiation source (26) activatable of producing a first output (28) having a wavelength of between 1.5 and 6.5 microns; a second radiation source (27) activatable o f producing a second output (30) having a wavelength of between 9.0 and 10.6 microns; a delivering arrangement (32) for effecting coaxialy of the first (28), and second (30) outputs and for concurrently delivering the outputs to the target site (22); wherein the first (28) and the second (30) outputs are selected such that the concurrent delivery of the first (28), and second (30 ) outputs to the target site (22) ablates the hard tissue (24) at the target site (22).
