Ultrasonic apparatus for thermotherapy with variable frequency for suppressing cavitation

An ultrasonic diagnosis apparatus for raising tissue temperature for hypothermic treatments, including an ultrasonic source for generating an ultrasonic treatment wave and a driving means for driving the ultrasonic source such that a frequency of the ultrasonic treatment wave generated by the ultrasonic source changes with time. The frequency of the ultrasonic treatment wave is changed along the time axis. By this change in frequency, some bubbles formed by cavitation as a result of the ultrasonic treatment wave are divided, and some bubbles are collapsed and therefore eliminated. Side effect cavitation and spread of a thermal degeneration area is suppressed, and thermal degeneration can be accurately induced in a desired area, thereby realizing a reliable, safe ultrasonic thermotherapy. Since cavitation is positively suppressed, the total treatment period can be shortened because cavitation would otherwise interfere with and slow down the thermal degeneration process. Therefore, treatment throughput can be improved as compared with a case in which cavitation is left to naturally break and disappear.

Synthesizing array for three-dimensional sound field specification

A non-invasive, synthesizing array of "N" reciprocal transducers is driven by "N" linearly independent inputs for three-dimensional sound field specification at "N" locations either within, or on, an isotropic or anisotropic acoustic/elastodynamic medium. Towards these ends, the impulse response, or Dyadic Green's Function Matrix, characteristic of the medium is determined, and the desired sound field response at "N" locations either within, or on, the surface of the medium is specified. This results in a system of "N" equations, which can be solved to obtain the "N" linearly independent inputs required to create the "N" desired, three-dimensional sound field responses. This permits precise focusing and spatial manipulation of sound intensity, as well as amplitude control within a specific volume or region of convergence within, or on, the medium.

Device and cartridge for hifu skincare

The present invention relates to a portable HIFU skin care device. The portable HIFU skin care device (1) of the present invention is divided into three portions. Firstly, a main body (100) has a rechargeable battery embedded therein, a power button and a step button installed therein for adjusting the intensity of an ultrasonic wave, and a display for displaying the operation states of the device, including the number of shots. In addition, a cartridge (200) is used by being mounted on a head part of the main body (100) and has a HIFU transducer embedded therein. A cradle (300) has a charging part which is installed therein, is capable of charging by being connected with the cartridge (200) and an adaptor, accommodates the main body (100) through a placement groove while the cartridge (200) is mounted to the main body (100), includes a UV lamp for disinfecting the head part of the cartridge (200) when accommodating the main body (100), and charges an internal battery of the main body (100). In an operation state, while the HIFU transducer is linearly moved for each one shot by a piezoelectric motor, a plurality of ultrasonic waves are emitted so as to form a plurality of ultrasonic focal point regions on an object, thereby achieving a skin care effect. In the present invention, the piezoelectric motor (216) is particularly installed inside the cartridge (200).
