PURPOSE:To facilitate the incision work after bleeding by providing a laser light guiding means for transmitting laser light for bleeding stop and incision to a laser guide, and setting an apex angle of a conical shape of a laser chip to an angle for bringing a laser light for incision to total reflection and condensing it to about the adjacent part of the center line of the laser chip, allowing a laser light for bleeding stop to transmit through and diffusing it to a wider range than that of the laser light for incision. CONSTITUTION:A laser probe main body 1 is inserted into a medical treatment purpose part in advance, and a tip chip 6 is placed so as to be opposed to the part to be irradiated in a blood vessel. Subsequently, from infrared laser and ultraviolet laser oscillating devices 8, 9, a laser light for bleeding stop and a laser light for incision are emitted, and led into a laser guide 3 in the laser probe main body 1, and also, into the tip chip 6. An apex angle of the tip chip 6 is set to an angle for bringing the emitted laser light for incision to total reflection and condensing it to about the adjacent part of the center line of the tip chip 6, and also, allowing the laser light for bleeding stop to transmit through and diffusing it to a wider range than that of the laser light for incision. Therefore, bleeding stop and incision of a living body tissue A can be executed simultaneously, and even if bleeding is generated from the living body tissue A at the time of executing a medical treatment for incising the living body tissue A, the incision work after bleeding is facilitated. |
