METHOD FOR PERFORMING AN OPTO-THERMO-MECHANICAL ACTION ON A BIOLOGICAL TISSUE AND DEVICE FOR CARRYING OUT SAID ACTION

摘要

The invention relates to a method for performing an opto-thermo-mechanical action on a biological tissue and to a device for carrying out said action. The inventive method consists in irradiating a biological tissue area by a modulated radiation which is spatially formed according to a specified law within an optical wavelength range having predetermined parameters and associated with a simultaneous thermal and mechanical action performed on said area (8), measuring, simultaneously with said irradiation of the biological tissue area, a spatial distribution of physico-chemical and geometrical characteristics in the area of a direct optical action and in an immediate proximity thereto with the aid of a test and diagnostic system (4), matching the parameters of the spatial formation and modulation of the optical radiation therebetween and with the biological tissue characteristics by means of a data processing unit (7) and in sending a control signal to a unit (2) for controlling the optical radiation power and the time modulation thereof, to a unit (3) for transferring optical radiation and forming the spatial distribution thereof on the surface and in the volume of the biological tissue (8) with the aid of said data processing unit. The optical radiation parameters are adjusted according to the control signals of the test and diagnostic system (4) during irradiating according to continuously measured characteristics of the spatial distribution of physico-chemical and geometrical characteristics in the area of the direct action performed on the biological tissue and beyond it.
