Abstract

A high-intensity focused ultrasound is configured such that a disposable separable cartridge is attached to and detached from the ultrasound device, so that a practitioner, i.e. a doctor, can obtain coordinates of a skin tissue of a subject using a scanner of an ultrasonic transducer and locate an accurate procedure point in real time. A procedure can be performed on the accurate procedure point of the skin tissue without repeated procedures.

Claims

1. A high-intensity focused ultrasound device comprising a hand piece comprising a hand piece body electrically connected to a freely movable body through a wire and a separable cartridge disposably coupled to the hand piece body,

wherein the hand piece body comprises:

a laser beam generator fractionally transferring energy to facilitate synthesis of collagen;

an ultrasonic transducer receiving electrical energy impedance-matched through a frequency generation process and a power amplification process to convert the received electrical energy into high-intensity focused ultrasound and irradiate the high-intensity focused ultrasound or receiving the reflected ultrasound;

an X-Y reflecting mirror undergoing a forward/backward movement and a tilting movement inside the hand piece body to sequentially form HIFU foci in a single row, in a plurality of rows, or in a circular row;

a cooling device supplying a cooling gas to the separable cartridge; and

a zoom-in device zooming in an image generated by reflected ultrasound,

wherein the separable cartridge comprises;

a cooling passage injecting a cooling gas, allowing the cooling gas to flow through a bottom surface of the separable cartridge, and lowering temperature; and

a transparent transmittance member supporting the cooling passage and coming into close contact with a skin tissue such that a laser beam and high-intensity focused ultrasound contact a portion of skin, and

wherein the movable body comprises;

a controller comprising an ultrasonic transducer-module controlling a frequency generation process and a power amplification process of the ultrasonic transducer, and power, a frequency, a duty cycle, a focus size, and a pulse repetition frequency, a reflecting mirror control module controlling the forward/backward movement and the tilting movement according to an X-axis and an Y-axis of the X-Y reflecting mirror, a cooling module lowering a temperature of the cooling device when a retreatment is performed, a coordinate module receiving information on converted coordinates through the ultrasonic transducer and locating a site currently treated, and a zoom-in module performing control to zoom in to the image generated by the reflected ultrasound;

a monitor unit comprising an indicator indicating information related to a procedure of a practitioner and a touch screen through which the practitioner operates or controls the high-intensity focused ultrasound generation device; and

a power supply supplying high-intensity focused ultrasound power.

2. The high-intensity focused ultrasound device of claim 1, wherein the controller further comprises:

a scanner locating a shape and a treatment position of the site currently treated, by receiving reflected ultrasound through the ultrasonic transducer; and

a cooling device driving unit lowering the temperature of the cooling device when a retreatment is performed on the site currently treated.

3. The high-intensity focused ultrasound device of claim 1, wherein the hand piece body further comprises a coordinate sensor,

wherein the coordinates sensor calculates coordinates of the HIFU foci concentrated in the single row, in the plurality of rows, or in the circular row to pass through the transparent transmittance member, and increases an amount of the cooling gas supplied to prevent a burn hazard when coordinates of newly concentrated HIFU foci match the calculated coordinates of the HIFU foci.

4. The high-intensity focused ultrasound device of claim 1, wherein the hand piece body further comprises a temperature sensor, and the controller receives a temperature measured by the temperature sensor in real time, determines in real time whether a temperature of the cooling gas is within an appropriate operation temperature range, and controls the temperature of the cooling device.

5. The high-intensity focused ultrasound device of claim 1, wherein the transparent transmittance member comprises a pair of ultrasound windows transmitting ultrasound disposed with respect to a laser beam window transmitting a laser beam or two pairs of ultrasound windows disposed in a cross shape with respect to the laser window.

6. The high-intensity focused ultrasound device of claim 2, wherein the hand piece body further comprises a coordinate sensor,

wherein the coordinates sensor calculates coordinates of the HIFU foci concentrated in the single row, in the plurality of rows, or in the circular row to pass through the transparent transmittance member, and increases an amount of the cooling gas supplied to prevent a burn hazard when coordinates of newly concentrated HIFU foci match the calculated coordinates of the HIFU foci.
