Title:
LASER THERAPEUTIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2006/030622
Kind Code:
A1
Abstract:
A laser therapeutic device capable of applying a laser beam uniformly and accurately only to a location to be treated with little thermal damage to normal tissues surrounding a lesion to be treated. The device comprises a laser oscillator (1) for generating a laser beam (30), a beam expander (10) for expanding the beam size of the laser beam (30) emitted from the laser oscillator (1), a laser scanning means (12) for scanning in an appropriate pattern the laser beam (30) incident via the beam expander (10), a condensing means (16) for finely narrowing down the laser beam (30) scanned by the laser scanning means (12), and an irradiation control means (6) for changing the irradiation time of the laser beam (30) finely condensed by the condensing means (16). A laser beam finely narrowed down is applied over the entire scanning area to enable a necessary amount to be applied effectively to only a location to be treated.
