Abstract

Provided is a 4th generation linear-focused-type high-intensity focused ultrasound system using 4th generation linear-focused-type high-intensity focused ultrasound (HIFU) in which an element array plate is formed in two stages and may be selectively used depending on a specific part of the human body. When the system is used for a deep area or a thin area depending on a specific part of the human body, a first stage and a second stage are selectively used, or the first stage and the second stage are used at the same time for intensive irradiation.

A 4th generation linear-focused-type high-intensity focused ultrasound system comprising:

a handpiece unit (100) comprising a left handpiece (110) and a right handpiece (120) provided outside a main body (700), and an element array plate (130) configured such that a plurality of piezoelectric elements is arranged thereon and disposed in the right handpiece;
and
a controller (200), a first high-intensity focused ultrasound operator (310), a second high-intensity focused ultrasound operator (320), a power supply (400), a mounting unit (500), and a display unit (600) provided in the main body (700), wherein:
the controller (200) controls operation of a high voltage generator (510) to generate high voltage to generate ultrasound when parameters are input by a user through a touch input unit (620), and the high voltage is transmitted to the piezoelectric elements of the handpiece unit (100) to generate the ultrasound;
the power supply (400) comprises a noise filter (410) and an SMPS (420), AC 200 V power is supplied and transmitted to the SMPS (420) through the noise filter (410), the power supplied to the SMPS (420) is converted to DC 24 V/12 V/5 V through an internal constant voltage circuit, and is output and supplied as driving powers of the controller (200), the display unit (LCD) (600), and respective parts, and some power is supplied to the high voltage generator (510) of the mounting unit (500);
the mounting unit (500) comprises the high voltage generator (510), a handpiece out (520), and a foot switch (530), and the handpiece unit (100) is mounted outside the mounting unit (500) so that the ultrasound generated by the main body is transmitted to a human body;
the display unit (600) comprises a display (610) and the touch input unit (620) on a front surface of the main body (700), and when the parameters are input by the user through the touch input unit (620), transmits the parameters to the controller (200), and displays data received from the controller (200) on the display (610);
the handpiece unit (100) is designed compactly to have a U-shaped concave inner surface to increase output performance, 350 piezoelectric elements are arranged in a two-layer structure with two rows in front and rear areas on the inner surface, and the piezoelectric elements are designed to form a focus at a maximum of 60 mm from a surface of focused ultrasound oscillated from a U-shaped structure of 65-70 R, if high voltage (5 kV-6 kV) pulses are applied to the piezoelectric elements for a short time (0.7-2 μs);
and
the controller (200) controls high voltage (6˜7 kV) pulses to be applied to the piezoelectric elements for a short time (0.7˜2 μs) so that the ultrasound rapidly increases and then exponentially decreases and then negative pressure occurs for a short time so as to generate high-intensity focused ultrasound (HIFU).
