A method of laser shock-wave treatment of pa-thological tissue in the treatment of degenera-tive diseases of the vagina and vulva

Currently, in gynecological practice, if necessary for medical reasons of destruction of pathological tissues the most successful methods used are thermal effects. For these purposes, generally use high-energy CO2 lasers, mechanism of action of which is to convert absorbed in a biotissue of laser energy into heat. Heating of biological tissue depends on the power and time of laser ex-posure. The degree of heating affects the depth of thermal degradation of biological tissue. However, when the laser thermal de-gradation there is the risk of increased bleeding when removing extensive foci of pathology with marked proliferation of the glandular epithelium. This marked also the frequent recurrence of the disease on the already deformed after laser coagulation of the vulva. The paper discusses the implementation mechanism of shock wave destructive effects on biological tissue with minimal thermal component, which provides a more effective treatment with minimal postoperative complications. The novelty of the method lies in the impact on surface structures of the biological tissue of elastic waves generated by explosions of fine particles with a large number of micro-pores filled with free water. When the absorption of laser radiation water filling the micropores of the particles is heated simultaneously with the particles. Upon reaching the temperature where the saturation vapor pressure of water exceeds the strength of the particles, the latter are destroyed. The process of destruction is explosive in nature.

This paper describes an algorithm for the treatment of degenerative diseases of the integumentary tissues using laser shock wave destructive impact with the use of laser radiation at a wavelength of 0.97 µm. The results of histological studies of the method on model objects, which used the skin of the vulva of minipigs, confirming the effectiveness of shock-wave impact.
