摘要：
FIELD: medicine.SUBSTANCE: in the presented device comprising a laser and a fibre-optic cable including an optic connector, a light guide with an optic core, an optic jacket and a protective polymeric jacket, an elongated diffuser with an optic core and an optic jacket, accommodating series an operational area, an optical area and a distal cone at the end, a protective cap made of an optically transparent inert material and having a cylindrical surface attached to the optic jacket in the operational area of the diffuser, and a heat-shrink protective tube on adjoining sections of the protective polymeric jacket of the light guide and the protective cap of the diffuser, covering the operational area of the diffuser. The surface of the optical area of the diffuser bears a spiral slot with a pitch distance not less than its width and no more than 1/2 lengths of the optical area of the diffuser. The slot depth smoothly increases towards the distal cone. The diffuser has a constant diameter in the operational area and an opening section of the optical area of the diffuser, a length of which makes at least 1/2 and no more than 3/4 of the length of the optical area of the diffuser, whereas in the other section of the optical area, the diffuser diameter monotonically decreases towards the distal cone. The distal cone diameter is equal to the lesser diameter of the diffuser a conical surface of the distal cone has an angle ranging within (38÷45)° in relation to the optical axis.EFFECT: device possesses high durability, safety and reliability.10 cl, 3 dwgИзобретение относится к медицинской технике, а более конкретно к устройствам для лазерного облучения сосудов и внутренних органов, которое вызывает изменение их стенок или образований на внутренней поверхности стенок под действием энергии лазерного излучения с определенной длиной волны.
