LASER ASSEMBLY Russian patent published in 2008 - IPC A61B18/26 

FIELD: medical equipment.

SUBSTANCE: laser assembly can be used in operative urology, for example, for curing benign hyperplasia of prostate and in lithotripsy for curing urolithiasis. Laser assembly has at least first laser radiator intended for lithotripsy of gallstones and second laser radiator intended for cutting and coagulation of tissues. First laser radiator is made for transform of radiation into second harmonica. It has laser resonator on base of Nd:YalO₃ crystal with modulation of Q-factor by shutter having damaged total internal reflection and with fiber-optic delay line. Laser radiator also has out-resonator radiation for transforming radiation into second harmonica of radiation at non-linear crystal to reach efficiency of transformation of 25% and higher. Second laser radiator has laser resonator on base of Nd:YAG crystal. Both radiators can be combined inside single laser assembly. Universal power source of pump lamps is used as well as integral control system and integral cooling system.

EFFECT: reduced cost of assembly; smaller sizes and weight.
