FIELD: medicine.
SUBSTANCE: invention relates to surgical instruments, applied for local freezing and destruction of isolated section of biological tissue and can be applied in general and pediatric surgery, oncology, dermatology, otolaryngology, gynecology and cosmetology. Inside cryonozzle with cold conductor-irradiator contains optic fibres, which are connected to source of laser irradiation and are brought to cryonozzle cold conductor with working ends. Cold conductor is made from optically transparent sapphire with one or several lengthy channels, in which optic fibres are placed.
EFFECT: increased efficiency of cryonozzle melting, as well as extension of possibilities of method of cryodestruction by transmission of laser irradiation directly into tissue for thermal impact and for fluorescent diagnostics.
