Abstract:
1. A surgical laser device comprising: a source of laser radiation optically coupled to a radiation guide having a proximal end and a distal end, the radiation guide serving to conduct the laser radiation between the proximal end and the distal end; the proximal end of the radiation guide serving to receive the laser radiation from the source; the distal end comprising a thermo-optical tip having absorption in the range of 0.5 to 1 serving to at least partially absorb the laser radiation, heat the thermo-optical tip with the laser radiation to a temperature ranging from 800 K to 1500 K and emit heat radiation indicative of the temperature of the thermo-optical tip; means to conduct the heat radiation from the distal end to the proximal end; a detector optically coupled to the proximal end for receiving the heat radiation and generating an output signal indicative of the temperature of the thermo-optical tip; and means responsive to the output signal for real-time controlling the source of the laser radiation to maintain the temperature of the thermo-optical tip at a predetermined level between 800 K and 1500 K for cutting biological tissue and maintaining a coagulation zone around a cut.
