[0025] FIG. 1 is a schematic perspective view illustrating an example of a high-intensity focused ultrasound device according to an embodiment of the present invention, FIG. 2 is a side view of the high-intensity focused ultrasound device of FIG. 1, and FIG. 3 is a block diagram of the high-intensity focused ultrasound device of FIG. 1.

[0026] Referring to FIGS. 1 to 3, the high-intensity focused ultrasound device (60) of the present embodiment may include a handpiece (650), a control signal supply unit (621), and an ultrasound generating unit (623).

[0027] A handpiece (650) is configured to allow a user to hold a portion of it and perform a procedure directly, and to transmit and receive electrical signals. A cartridge (600) positioned toward the treatment target may be connected to the handpiece (650). The handpiece (650) may include an operation button (651) that controls the operation of the cartridge (600), and the electrical signal transmitted through the operation button (651) can control the oscillation of ultrasound.

[0028] The cartridge (600) can be detachably mounted on the handpiece (650). Depending on the type and purpose of the procedure, the user can detach the cartridge (600) and select and use an appropriate cartridge (600). When the cartridge (600) is mounted on the handpiece (650), it can be electrically connected to the handpiece (650) and can transmit and receive electrical signals to control the oscillation of ultrasound. The lower surface of the cartridge (600) can be positioned to face the treatment target, for example, to face the skin surface so that ultrasound can be irradiated and focused into the skin layer.

[0029] As an optional embodiment, the high-intensity focused ultrasound device (60) may include a separation button (1). The separation button (1) is intended to facilitate the separation of the handpiece (650) and the cartridge (600), for example, to separate the fixing parts of the handpiece (650) and the cartridge (600) to release the connection. The user can easily replace the cartridge (600) through the separation button (1) and perform precise and accurate procedures by changing the cartridge (600) according to the type of procedure, the degree of wear of the cartridge (600), the usage cycle of the cartridge (600), etc.

[0030] The control signal supply unit (621) can generate a control signal to control the oscillation of ultrasound. The control signal generated by the control signal supply unit (621) may be a signal for operating or controlling the operation of a high-intensity focused ultrasound device (60), including, for example, whether the ultrasound device (60) is operating, the number of operations, the operation time, etc. Additionally, the control signal may be a signal for controlling the oscillation of a specific ultrasound, including, for example, whether the ultrasound generator (623) is selectively operating, the depth of skin penetration of the ultrasound, frequency, amplitude, phase, etc.

[0031] The control signal supply unit (621) may be electrically connected to the handpiece (650) to supply power to the motor of the handpiece (650) or to transmit a control signal to the handpiece (650). For example, the control signal supply unit (621) may be located outside the handpiece (650) and may be wired to the handpiece (650) via a cable (662). As another example, the control signal supply unit (621) and the handpiece (650) may be wirelessly connected. As an example, the control signal supply unit (621) may be a main body including a control board that is connected to the handpiece (650) to supply power and transmit and receive electrical signals. As yet another example, the control signal supply unit (621) may be built inside the handpiece (650).

[0032] As an optional embodiment, the control signal supply unit (621) may include a high-frequency generator. The high-frequency generator may generate a high frequency required for driving the ultrasonic generator (623). The high frequency required for driving the ultrasonic generator (623) may be, for example, RF corresponding to the driving frequency at which the ultrasonic generator (623) can output ultrasound. The control signal supply unit (621) may control the output of the high frequency generated by the high-frequency generator. For example, the control board of the main body or handpiece (650) may control whether to output the high frequency, selective output of the high frequency, power, etc.

[0033] The ultrasonic generating unit (623) can generate ultrasonic waves corresponding to the high frequency generated by the high frequency generator. The ultrasonic generating unit (623) may include a transducer capable of converting electrical energy into physical energy. As an example, the transducer may be formed of a ceramic-based material.

[0034] Transducers may have the same or different driving frequencies. The driving frequency may be, for example, a frequency at which energy conversion is maximized, allowing the transducer to generate mechanical vibrations of maximum amplitude. The ultrasound generated by transducers having the same or different driving frequencies may be the same or different. The ultrasound may have different characteristics depending on the thickness, material, etc., of the transducer, and these characteristics may include, for example, frequency and the distance at which the focus is formed during the procedure.

[0035] When multiple transducers output the same ultrasound, they generate ultrasound with the same characteristics simultaneously or sequentially, which can improve the speed of the procedure and reduce the procedure time compared to using a single transducer.

[0036] When multiple transducers output different ultrasounds, various procedures can be performed by combining transducers with appropriate frequencies and penetration depths depending on the type, size, location, and tissue condition of the target.

[0037] The ultrasound generating unit (623) can be embedded inside the cartridge (600). The ultrasound generating unit (623) can output focused ultrasound toward the skin surface through the lower surface of the cartridge (600). By arranging multiple transducers with characteristics suitable for the procedure in a single cartridge (600), various ultrasounds can be output without exchanging the cartridge (600). This reduces the inconvenience of having to replace the cartridge (600) of the ultrasound device (60) for each procedure and improves the convenience and efficiency of the procedure.

[0038] The high-intensity focused ultrasound device (60) of the present embodiment may include a cartridge board (622). The cartridge board (622) may be embedded inside the cartridge (600). The control signal supply unit (621) and the cartridge board (622) may be electrically connected when the cartridge (600) is mounted on the handpiece (650), and may transmit and receive electrical signals.

[0039] The cartridge board (622) can transmit a control signal transmitted by the control signal supply unit (621) to the ultrasonic generator (623). The control signal may be a signal for operating or controlling the operation of the high-intensity focused ultrasound device (60) or a signal for controlling the oscillation of a specific ultrasound, for example, a signal for controlling whether the ultrasound device (60) is operating, the number of operations, the operating time, etc., or a signal for controlling the skin penetration depth, frequency, amplitude, phase, etc. of the ultrasound. Additionally, the cartridge board (622) can transmit a high frequency generated by the high frequency generator to the ultrasonic generator (623).

[0040] The cartridge board (622) can store transducer information of the ultrasonic generator (623). For example, the transducer information may include the frequency of the ultrasonic waves output by each transducer, skin penetration depth, usage information, lifespan, and other security information. The control signal supply unit (621) can receive transducer information from the cartridge board (622) and generate a control signal corresponding thereto. As a specific example, the high-frequency generator of the control signal supply unit (621) can generate a high frequency corresponding to the driving frequency of the transducer. The generated high frequency can be distributed to the ultrasonic generator (623) through the cartridge board (622), and the transducer of the ultrasonic generator (623) can output ultrasonic waves corresponding thereto.

[0041] For example, the cartridge board (622) can communicate with the control board of the main body or handpiece (650) to transmit information about the transducer, and the control board can control the RF output based on the transducer information.

[0042] Through the stored information of the cartridge board (622), the control signal supply unit (621) can generate a rapid and accurate control signal, and the ultrasound generator (623) can generate ultrasound of the corresponding characteristics to provide a fast procedure speed and improved procedure efficiency.

[0043] According to the present embodiment, an ultrasonic control unit (620) comprising a control signal supply unit (621), a cartridge board (622), and an ultrasonic generator (623) can generate and transmit a control signal to control the oscillation of ultrasonic waves, and can generate ultrasonic waves corresponding to this to control the output of ultrasonic waves.

[0044] FIG. 4 is a block diagram illustrating an optional embodiment of the ultrasonic control unit of FIG. 3.

[0045] Referring to FIG. 4, the control signal supply unit (221) of the ultrasonic control unit (220) according to the present embodiment may include a high-frequency generator (21), and the ultrasonic generating unit (223) may include a plurality of transducers (23). The transducers (23) can convert electrical energy into physical energy, and as an example, the transducers (23) may be formed of a ceramic-based material.

[0046] The high-frequency generator (21) can generate high frequency for driving the transducer (23). The high-frequency generator (21) may be provided in multiple units to generate high frequency for multiple transducers (23), and may generate multiple high frequencies. Multiple high frequencies can be transmitted to multiple transducers (23) through the cartridge board (222), and each transducer (23) can output ultrasonic waves.

[0047] By generating multiple high frequencies for multiple transducers (23), problems regarding the matching of transducer (23) characteristics and manufacturing can be resolved. The cost and time required to manufacture transducers (23) with matching driving frequencies and impedances can be reduced, and the probability of failure due to mismatch between the circuit and the transducer (23) can be lowered. The transducer (23) does not need to wait to receive a control signal through a switching circuit, and multiple transducers (23) can be driven simultaneously through multiple high frequencies, thereby shortening the procedure time.

[0048] According to the present embodiment, a plurality of transducers (23) can be arranged and controlled in a single cartridge to stably generate a plurality of various ultrasounds, and a procedure using ultrasounds having different frequencies and skin penetration depths can be efficiently performed by combining the transducers (23) in various ways.

[0049] FIG. 5 is a block diagram illustrating a variation of FIG. 4.

[0050] Referring to FIG. 5, a plurality of high-frequency generators (31) of the ultrasonic control unit (320) according to the present variation may correspond one-to-one with a plurality of transducers (33). A cartridge board (322) may be provided with a matching circuit (32) that corresponds one-to-one with the high-frequency generators (31) and the transducers (33). The cartridge board (322) may connect the transducers (33) and the high-frequency generators (31).

[0051] The cartridge board (322) can store and transmit information corresponding to the transducer (33). For example, the cartridge board (322) can store the frequency of the ultrasound output by each transducer (33), skin penetration depth, usage information, lifespan, and other security information. The control signal supply unit (321) can generate a control signal corresponding to the information received from the cartridge board (322), and as a specific example, the high-frequency generator (31) of the control signal supply unit (321) can generate RF corresponding to the driving frequency of the transducer (33). The generated high frequency can be distributed to the ultrasound generator (323) through the cartridge board (322), and the transducer (33) of the ultrasound generator (323) can output ultrasound corresponding to it.

[0052] For example, the cartridge board (322) can communicate with the control board of the main body or handpiece to transmit information of the transducer (33), and the control board can control the RF output based on the information of the transducer (33).

[0053] One high-frequency generator (31) can generate one high frequency for driving one matched transducer (33). The transducer (33) of the ultrasonic generator (323), which receives a control signal through the cartridge board (322), can output an ultrasonic wave having one characteristic.

[0054] The high frequency applied to each transducer (33) can be independently managed and controlled to control the transducers (33) individually, and the output ultrasound can be controlled accordingly. For example, the high frequency generator (31) can control the ultrasound oscillation of the transducers (33) by outputting the high frequency simultaneously, selectively, or sequentially. For each transducer (33), the number of driving cycles, driving time, intensity of the generated ultrasound, frequency, and focal depth of the transducer (33) can be controlled separately, and the transducer (33) can generate ultrasound with a frequency and output intensity optimized for the procedure. By generating ultrasound and using the same or different outputs, various procedures can be performed using a single cartridge, and the efficiency and convenience of the procedure can be improved.

[0055] In addition, the probability of various ultrasonic oscillation problems related to the characteristics of the transducer (33), such as heat generation in the circuit due to the difference in impedance between the input high frequency and the transducer (33), heat generation in the transducer (33), reduced efficiency of the procedure, and increased risk of burns to the patient, can be reduced, and the stability and reliability of the device can be improved.

[0056] Through a one-to-one matching method between the high-frequency generator (31) and the transducer (33), the circuit structure can be simplified, and fast operation and response speeds can be secured, while simultaneously generating ultrasonic waves with different frequencies stably. Even if a problem occurs in some circuits, only the corresponding circuit configured independently can be modified without affecting other circuits, and the stability of the entire circuit can be increased. In addition, the complex structure and failure problems of the switching circuit and speed limitations can be resolved, and the ultrasonic oscillation of multiple transducers (33) can be efficiently controlled.

[0057] Multiple transducers (33) can be arranged and controlled in a single cartridge to stably generate multiple different ultrasounds, and by combining the transducers (33) in various ways, procedures using ultrasounds with different frequencies and skin penetration depths can be efficiently performed.

[0058] Ultrasound of various characteristics can be output stably and quickly through a high-frequency generator (31) that corresponds one-to-one with the transducer (33). Ultrasound with different frequencies and focal depths can be generated using a single cartridge without replacing the cartridge, and various procedures can be performed.

[0059] FIG. 6 is a flowchart illustrating a method for controlling a high-intensity focused ultrasound device according to one embodiment of the present invention.

[0060] Referring to FIG. 6, the high-intensity focused ultrasound device control method of the present embodiment may include a control signal supply step (S10), a control signal transmission step (S20), and an ultrasound generation step (S30).

[0061] The control signal supply step (S10) can generate a control signal that controls the oscillation of ultrasound. The control signal may be a signal for operating or controlling the operation of a high-intensity focused ultrasound device, including, for example, whether the ultrasound device is operating, the number of operations, the operation time, etc. Additionally, the control signal may be a signal for controlling the oscillation of a specific ultrasound, including, for example, the skin penetration depth, frequency, amplitude, phase, etc.

[0062] The control signal can be transmitted to a high-intensity focused ultrasound device to generate ultrasound. The control signal can be transmitted via a wired connection through a cable or via a wireless connection.

[0063] The control signal generated through the control signal supply step (S10) can control the high-intensity focused ultrasound device and ultrasound oscillation and can generate ultrasound having various characteristics.

[0064] The control signal transmission step (S20) can transmit a control signal generated through the control signal supply step (S10). The control signal may be a signal for operating or controlling the operation of a high-intensity focused ultrasound device or a signal for controlling the oscillation of a specific ultrasound, for example, a signal for controlling whether the ultrasound device is operating, the number of operations, the operating time, etc., or a signal for controlling the skin penetration depth, frequency, amplitude, phase, etc. of the ultrasound.

[0065] Control signals can be transmitted by the cartridge board of the high-intensity focused ultrasound device, and the cartridge board can store and transmit / receive information necessary for ultrasound generation. For example, the cartridge board can store transducer information including the frequency of the ultrasound output by each transducer, skin penetration depth, usage information, lifespan, and other security information. The cartridge board can store frequency information necessary for driving the transducers and, based on this, can rapidly and accurately transmit control signals to control the high-intensity focused ultrasound device and the oscillation of ultrasound.

[0066] The control signal transmitted through the control signal transmission step (S20) can control the high-intensity focused ultrasound device and ultrasound oscillation and can generate ultrasound having various characteristics.

[0067] The ultrasonic generation step (S30) can generate ultrasonic waves corresponding to a control signal through an ultrasonic generation unit comprising one or more transducers. The transducer can convert electrical energy into physical energy and generate ultrasonic waves, and as an example, the transducer can be formed of a ceramic-based material.

[0068] The ultrasound generated by the transducer in the ultrasound generation step (S30) may be the same or different. The ultrasound may have different characteristics depending on the thickness, material, etc. of the transducer, and the characteristics may be, for example, frequency, the distance at which the focus is formed during the procedure, etc.

[0069] When multiple transducers output the same ultrasound, they generate ultrasound with the same characteristics simultaneously or sequentially, which can improve the speed of the procedure and reduce the procedure time compared to using a single transducer.

[0070] When multiple transducers output different ultrasound waves, various procedures can be performed by combining transducers with appropriate frequencies and penetration depths depending on the type, size, location, and tissue condition of the target. This reduces the inconvenience of having to replace the ultrasound device cartridge for every procedure and improves procedural convenience and efficiency.

[0071] Ultrasound with various characteristics can be generated through the ultrasound generation step (S30), and the generated ultrasound can be irradiated and focused into the skin layer.

[0072] Figure 7 is a flowchart illustrating a variation of Figure 6.

[0073] Referring to FIG. 7, the control signal supply step (S10) may include a high frequency generation step (S11).

[0074] The high-frequency generation step (S11) can generate a high frequency required for driving the ultrasonic generator. The high frequency required for driving the ultrasonic generator may be, for example, RF corresponding to the driving frequency for the ultrasonic output of the ultrasonic generator.

[0075] The high-frequency generation step (S11) can generate multiple high frequencies so as to correspond one-to-one with an ultrasonic generator including a transducer.

[0076] The problem of matching transducer characteristics and manufacturing issues can be resolved through multiple high frequencies generated via the high frequency generation step (S11). The cost and time required to manufacture transducers with matching driving frequencies and impedances can be reduced, and the probability of problems occurring, such as circuit overheating, transducer overheating, reduced procedure efficiency, and increased risk of burns to the patient caused by the difference in impedance between the input high frequency and the transducer, can be lowered. The transducer does not need to wait to receive a control signal through the switching circuit, and multiple high frequencies can drive multiple transducers simultaneously, thereby shortening the procedure time.

[0077] The high-frequency generation step (S11) can form a simple circuit and improve response and procedure speed by matching the high frequency with multiple transducers one-to-one.

[0078] By independently managing and controlling the high frequency applied to each transducer, the transducers can be controlled individually, and the output ultrasound can be controlled accordingly. For example, by controlling whether each transducer is driven, all or only some of the transducers can be driven, or they can be driven simultaneously or sequentially. Additionally, for each transducer, the number of times the transducer is driven, the driving time, the intensity, frequency, and focal depth of the generated ultrasound can be controlled separately.

[0079] The high frequency generated through the high frequency generation step (S11) can be distributed to the ultrasonic generator through the control signal transmission step (S20), and the transducer of the ultrasonic generator can output the corresponding ultrasonic through the ultrasonic generation step (S30).
