METHOD FOR CERVIX, VAGINA AND VULVA DYSTROPHIC DISEASES TREATMENT BY SHOCKWAVE METHOD AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2017 - IPC A61B18/26 

FIELD: medicine.

SUBSTANCE: tissue with pathological changes is coated with fine particles of carbon dye. The coating is exposed to pulsed laser radiation. At the beginning of radiation, laser irradiation pulse power is set lower than the value expected for this threshold pathology. The repetition frequency of acoustic pulses generated by a surface thermal microexplosion and absorbing the laser emission of carbon dye particles is determined. It is compared to the laser pulses frequency. Laser pulses power is sequentially increased to a value at which the acoustic pulse frequency becomes equal to the repetition frequency of laser pulses. Irradiation is performed with this pulse power value. The device includes a laser operating in a pulse-periodic mode of laser radiation generation, a laser radiation operating parameters control unit, a laser radiation parameters measuring unit and an indication unit. It additionally contains an acoustic microphone, a selectable band-pass filter for a maximum range of 5-7 kHz, microphone signal amplifier and a two-input coincidence circuit, all connected in series. One of the coincidence circuit inputs is connected to the microphone signal amplifier output, the second icoincidence circuit input is connected to the laser pulses repetition driving frequency generator output, and output - to the laser radiation operating parameters control unit input and the indication unit.

EFFECT: increased efficiency of treatment and reduced probability of postoperative recurrence and scar development processes through implementation of objective selection and monitoring of the adequacy of defined laser radiation parameters, providing the process of shock wave destruction.
