The present invention provides a phase-controlled high-energy focusing ultrasonic intelligent therapeutic device used in surgery. The phase-controlled high-energy focusing ultrasonic intelligent therapeutic device comprises the following components: a computer, a B-ultrasonic machine, a probe rotating device, a focusing power ultrasonic transmitter and a three-dimensional mechanical motion digital control signal generator. The focusing power ultrasonic transmitter is also installed with a spherical universal joint and a flexible shaft. The universal joint is installed on the upper end of ultrasonic transmitter. The soft shaft transverses the spherical universal joint. One end of the soft shaft is connected with a spherical universal movement digital control signal source which controls the rotation of spherical universal joint. The spherical universal movement digital control signal source is connected with the computer. The three-dimensional mechanical motion digital control signal generator is connected with a spherical universal joint of focusing power ultrasonic transmitter. The therapeutic device can better regulate the dose of ultrasonic and has an irradiation effect better than that of extracorporeal irradiation.
