Abstract

FIELD: medical engineering. SUBSTANCE: device has pulsating laser, focussing system, guidance system and unit for placing skin surface to be perforated, into the laser radiation focus zone between the focussing system and its focal plane 1.5-8 mm distant from the focal plane. Focussing system focal length, diameter of laser beam focused on the skin surface and laser radiation power density on the skin surface are to be calculated from formulas shown in the invention application. EFFECT: reduced pain felt during operation.
