Abstract
Abstract Apparatus for laser therapy is designed for therapeutic and surgical action of laser emission upon tissue in clinical practice, as well as for wide application in a variety of medical and biological experiments. The apparatus comprises one or several lasers, a light guide to transmit the laser emission from a laser head to a particular point in the operation area, as well as a focusing barrel and/or a flexible light guide providing a means for irradiating or dissecting the tissue. The apparatus is provided, in accordance with the invention, with a scanning device featuring a focusing barrel and a flexible light guide and comprising at least two platforms for transverse and longitudinal travel in a horizontal plane with reflecting elements placed thereupon to permit transmission of the laser beam along the optical axis of the focusing barrel or the flexible guide, thus making it possible to combine in one apparatus irradiation by powerful laser emission and continuous laser emission for dissection of tissue in surgery.
