| 摘要 |
This ultrasonic treatment device is provided with: a therapeutic ultrasound irradiation unit (3) that irradiates a biological tissue (S) with focused ultrasonic waves (U1) and heats the vicinity of the focal point (F) of the focused ultrasonic waves (U1), said point being located in a deep portion of the biological tissue (S), to a temperature at or above the thermal denaturation temperature of the biological tissue (S); and a preheating energy irradiation unit (4) that irradiates the biological tissue (S) with energy waves (U2) and heats the vicinity of the focal point (F) to a temperature that is less than the thermal denaturation temperature. The preheating energy irradiation unit (4) irradiates the biological tissue with energy waves (U2) that do not exert a heating effect on the biological tissue (S) located between the therapeutic ultrasound irradiation unit (3) and the focal point (F). |
