[0002] Recently, with the growing interest in skin aesthetics, various procedures and medical devices are being developed to prevent skin aging, improve wrinkles, and maintain elasticity. However, procedures and devices such as micro-needle rollers and laser treatments are invasive methods that inflict physical damage on the skin. Due to issues such as pain, bleeding, downtime, and safety concerns, an increasing number of people are feeling aversion to treatments using invasive devices.

[0003] Accordingly, High-Intensity Focused Ultrasound (HIFU) devices, which treat using ultrasound without direct incisions in the skin, are attracting attention. HIFU devices utilize high-intensity focused ultrasound to accurately deliver energy to deep layers of the skin, thereby providing non-invasive skin improvement effects. However, since HIFU devices contain various internal components, they require complex design and manufacturing processes, such as component placement, electrical connections, waterproofing, and precision assembly; therefore, technology capable of ensuring the performance and stability of HIFU devices is required.

[0004] Embodiments of the present invention provide a method for controlling a high-intensity focused ultrasound device with improved procedure speed and convenience, and enhanced procedure efficiency and stability. Additionally, the invention provides a high-intensity focused ultrasound device with improved alignment accuracy of a cartridge module and a method for manufacturing a high-intensity focused ultrasound device.

[0005] However, the technical problems that the present invention aims to solve are not limited to those described above, and other unmentioned problems can be clearly understood by those skilled in the art from the description of the invention below.

[0007] According to embodiments of the present invention, the manufacturing process of the cartridge module can be simplified to reduce module assembly time, and manufacturing convenience and assembly accuracy can be improved. In addition, it is possible to control the oscillation of ultrasound having various characteristics and provide fast operation and response speeds.

[0066] In the following embodiments, the x-axis, y-axis, and z-axis are not limited to three axes in an orthogonal coordinate system and can be interpreted in a broader sense that includes them. For example, the x-axis, y-axis, and z-axis may be orthogonal to each other, but they may also refer to different directions that are not orthogonal to each other.

[0067] Where an embodiment can be implemented differently, a specific process sequence may be performed differently from the order described. For example, two processes described consecutively may be performed substantially simultaneously or proceed in the reverse order of the description.

[0068] 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.

[0069] Referring to FIGS. 1 to 3, the high-intensity focused ultrasound device (60) of the present embodiment may include a main body (650), a control signal supply unit (621), and an ultrasound generating unit (623).

[0070] The main body (650) is configured to allow a user to hold a portion of it and perform a procedure directly, and may be formed to transmit and receive electrical signals. A cartridge (600) positioned to face the procedure target may be connected to the main body (650). The main body (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) may control the oscillation of ultrasound.

[0071] The cartridge (600) can be detachably mounted on the main body (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 main body (650), it can be electrically connected to the main body (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 target of the procedure, for example, so that ultrasound can be irradiated and focused onto the skin layer.

[0072] In one embodiment, the high-intensity focused ultrasound device (60) may include a separation button (1). The separation button (1) is intended to facilitate separation of the main body (650) and the cartridge (600), and may, for example, be used to separate the fixing parts of the main body (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 age of the cartridge (600), the usage cycle of the cartridge (600), etc.

[0073] 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.

[0074] The control signal supply unit (621) may be electrically connected to the main body (650) to supply power to the motor of the main body (650) or to transmit a control signal to the main body (650). For example, the control signal supply unit (621) may be located outside the main body (650) and may be wired to the main body (650) via a connecting line (662). As another example, the control signal supply unit (621) and the main body (650) may be wirelessly connected. As an example, the control signal supply unit (621) may be a device including a control board that is connected to the main body (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 main body (650).

[0075] In one 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 (650) may control whether to output the high frequency, selective output of the high frequency, power, etc.

[0076] 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.

[0077] 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.

[0078] 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.

[0079] 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.

[0080] 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.

[0081] 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 main body (650), and may transmit and receive electrical signals.

[0082] 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).

[0083] 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.

[0084] For example, the cartridge board (622) can communicate with the control board of the main body (650) to transmit information about the transducer, and the control board can control the RF output based on the transducer information.

[0085] 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.

[0086] 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.

[0087] FIG. 4 is a block diagram illustrating an embodiment of the ultrasonic control unit of FIG. 3.

[0088] 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.

[0089] 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.

[0090] 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.

[0091] 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.

[0092] FIG. 5 is a block diagram illustrating a variation of FIG. 4.

[0093] 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).

[0094] 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.

[0095] For example, the cartridge board (322) can communicate with the control board of the main body to transmit information of the transducer (33), and the control board can control the RF output based on the information of the transducer (33).

[0096] 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.

[0097] 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.

[0098] 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.

[0099] 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.

[0100] 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.

[0101] 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.

[0102] FIG. 6 is a perspective view schematically illustrating another example of a high-intensity focused ultrasound device, FIG. 7 is a side view of the high-intensity focused ultrasound device of FIG. 6, and FIG. 8 is a block diagram of the high-intensity focused ultrasound device of FIG. 6.

[0103] Referring to FIGS. 6 to 8, the high-intensity focused ultrasound device (2060) may include a cartridge (2600) comprising a main body (2650) and a cartridge module (2610).

[0104] The ultrasonic device (2060) can be applied by modifying the aforementioned embodiments and variations within the same or similar range, and a detailed description thereof is omitted. Below, the description focuses on the configuration or features that are distinct from the aforementioned embodiments and variations.

[0105] The main body (2650) may include a motor (2652) and may be formed to transmit and receive electrical signals. An electrical signal transmitted to the main body (2650) can operate the motor (2652). Depending on the operation of the motor (2652), the moving part (2617) of the cartridge module (2610) may move back and forth along the moving rail (2615).

[0106] A moving part (2617) that moves along a moving rail (2615) fixed to a moving rail support (2614) may be located at the top of the cartridge module (2610). The moving part (2617) may move in a reciprocating sliding motion by a motor (2652).

[0107] The cartridge module (2610) may further include a bellows. The bellows may contract or expand according to the movement of the moving part (2617) and may be waterproof to prevent the ultrasonic transmission medium from coming out of the cartridge (2600).

[0108] At the bottom of the cartridge module (2610), one or more transducers (2640) that generate focused ultrasound and at least one transducer housing (2630) that accommodates the transducers (2640) may be located.

[0109] An ultrasonic transmission film may be attached to the area where the cartridge (2600) comes into contact with the skin. The focused ultrasound generated by the transducer (2640) may be irradiated into the skin layer through the ultrasonic transmission film on the lower surface of the cartridge (2600).

[0110] The high-intensity focused ultrasound device (2060) of the present embodiment may further include a control module (2660).

[0111] The control module (2660) may be for operating or manipulating the high-intensity focused ultrasound device (2060) by transmitting an electrical signal that controls the driving of the motor (2652) and the output of the high-intensity focused ultrasound. Additionally, the control module (2660) may be for providing power to the high-intensity focused ultrasound device (2060).

[0112] In one embodiment, the control module (2660) may provide and display information related to the procedure. The information related to the procedure may be, for example, the power status, number of operations, operation time, operation frequency, skin penetration depth, etc. of the high-intensity focused ultrasound device (2060).

[0113] The control module (2660) may be electrically connected to the main body (2650). For example, the control module (2660) may be connected to the main body (2650) via an external connection line (2662), and as another example, the control module (2660) and the main body (2650) may be wirelessly connected. As yet another example, the control module (2660) may be located within the main body (2650) to transmit and receive electrical signals.

[0114] The electrical signal of the control module (2660) can be transmitted to the motor (2652) of the main body (2650) and the transducer (2640) of the cartridge (2600). The control module (2660) can control the driving of the motor (2652) and the output of ultrasonic waves through the transducer (2640), and can, for example, control the rotation of the motor (2652), whether one or more transducers (2640) are selectively operated, the operating frequency, the number of operations, the operating time, etc.

[0115] A transducer (2640) that receives an electrical signal can output focused ultrasound toward the skin surface through the lower surface of the cartridge (2600). In one embodiment, the electrical signal may be transmitted to a plurality of transducers (2640) and may be a signal for frequency generation and identical or different ultrasound output of the plurality of transducers (2640).

[0116] FIG. 9 is a diagram illustrating an embodiment of a transducer of the high-intensity focused ultrasound device of FIG. 6.

[0117] Referring to FIG. 9, the transducer (2640') according to the present embodiment may be in the form of a circle with both ends cut parallel to each other. For example, it may be a bridge-type transducer (2640') in which both ends of a circle-type transducer (2640') are cut equally.

[0118] When multiple transducers (2640') and transducer housings are placed in a single cartridge, the size of the cartridge increases, making it difficult to adhere to the skin surface of the patient, which may result in a problem where the reach distance of the focused ultrasound is shortened. The high-intensity focused ultrasound device of this embodiment can solve the problem of increased cartridge volume and weight by reducing the skin contact surface and the size of the cartridge. In addition, by maximizing the adhesion to the skin, the possibility of skin damage such as burns or scratches can be reduced, thereby improving safety and the precision of the procedure.

[0119] At this time, the size and shape of the transducer (2640') can be designed considering performance such as ultrasonic output strength. For example, the transducer (2640') according to the present embodiment may be a small bridge-type transducer (2640') in which both ends of a small one-type transducer (2640') are cut equally, and the diameter of the small one-type transducer (2640') may be 50% of the diameter of the existing one-type transducer (2640').

[0120] By changing or miniaturizing the size and shape of the transducer (2640'), multiple transducers (2640') and transducer housings can be placed in a single cartridge, and space efficiency can be increased to solve the problems of increased volume and weight and tightness of the high-intensity focused ultrasound device including the cartridge.

[0121] FIG. 10 is a drawing illustrating an example of a cartridge module, and FIG. 11 is a perspective view of FIG. 10.

[0122] Referring to FIGS. 10 and 11, the high-intensity focused ultrasound device according to the present embodiment may include a cartridge comprising a cartridge module (2210) and may further include a main body, although not illustrated. The main body may be applied in various forms, for example, the main body of the aforementioned embodiment or a modified example may be applied.

[0123] A moving rail support (2214), a moving rail (2215), and a moving part (2217) that slides along the moving rail (2215) may be located at the top of the cartridge module (2210).

[0124] The movable rail (2215) can be fixed by the movable rail support (2214), and the movable part (2217) can move back and forth by being constrained at one end to the movable rail (2215). The bellows (2212) can contract or expand according to the movement of the movable part (2217) and may be waterproof to prevent the ultrasonic transmission medium from coming out of the cartridge.

[0125] At the bottom of the cartridge module (2210), one or more transducers and at least one transducer housing (2230) for accommodating the transducers may be positioned so as to face the treatment target.

[0126] The transducer may have a concave shape facing the skin surface and can form a thermal focus by focusing ultrasound to a spaced-apart location. As an example, the transducer may be formed of a ceramic-based material.

[0127] The transducer housing (2230) may have a curvature corresponding to the transducer having a concave shape. The transducer can perform a procedure by focusing and irradiating ultrasound toward the skin surface through the transducer housing (2230) and the lower surface of the cartridge.

[0128] The cartridge module (2210) according to the present embodiment may include a housing plate (2221). One side of the housing plate (2221) may be coupled to a transducer housing (2230), and the other side may be coupled to a moving part (2217). The housing plate (2221) coupled to the moving part (2217) may slide back and forth according to the movement of the moving part (2217), and the transducer housing (2230) coupled to the housing plate (2221) may slide back and forth according to the movement of the housing plate (2221).

[0129] At this time, the housing plate (2221) can be combined with a plurality of transducer housings (2230a, 230b, 230c), and the plurality of transducer housings (2230a, 230b, 230c) can slide back and forth together as the housing plate (2221) moves.

[0130] A transducer housed in a transducer housing (2230) can irradiate focused ultrasound while moving together with a housing plate (2221) and a transducer housing (2230) that move according to the movement of a moving part (2217). The transducer may have a treatment range according to the range of movement of the moving part (2217), and the treatment range may be adjusted according to the type of treatment, target size, shape, frequency of ultrasound, skin penetration depth, etc.

[0131] FIG. 12 is a cross-sectional view illustrating one embodiment of the transducer housing of FIG. 10.

[0132] Referring to FIG. 12, the transducer housing (330) can accommodate a transducer (340) that generates focused ultrasound, and as an example, the transducer (340) can be formed of a ceramic-based material. The transducer (340) can be fixed to the transducer housing (330) and can be sealed to the transducer housing (330) for waterproofing. Additionally, the transducer (340) can be electrically connected to a PCB (341) mounted on the top of the transducer housing (330) for driving.

[0133] The transducer housing (330) according to the present embodiment may include a housing coupling part (343) that can be coupled with a housing plate. The transducer housing (330) and the housing plate may be coupled in various ways, and the transducer housing (330) may be detachably attached to the housing plate. The transducer housing (330) coupled through the housing coupling part (343) can maintain a stable state without shaking or change of position even during a procedure or when moving along a moving rail, and can be easily detached without damaging the parts when necessary.

[0134] For example, the housing coupling portion (343) may be a detachable structure that fastens the transducer housing (330) into a groove formed in the housing plate. As a specific example, the transducer housing (330) may include a locking portion formed with a protruding outer surface, and the housing plate may include a locking groove.

[0135] For example, the hook portion may be in the form of a hook formed to secure the transducer housing (330) to the inner side of the hook groove of the housing plate. The hook can be coupled to the housing plate in a fitting manner, thereby allowing the transducer housing (330) to be coupled to the hook groove of the housing plate and secured without shaking during the procedure, and can be easily detached as needed.

[0136] In addition to this, various physical coupling methods can be used to maintain and separate the coupling of the transducer housing (330) and the housing plate through a coupling means.

[0137] The user can select a transducer (340) having characteristics suitable for the treatment area or purpose and attach it to the cartridge module via the transducer housing (330). For example, by combining a transducer housing (330) that accommodates a transducer (340) having a thickness corresponding to the required frequency and coupling it to the cartridge module, focused ultrasound with a desired frequency, skin penetration depth, and intensity can be generated.

[0138] By arranging multiple transducers (340) and transducer housings (330) having various characteristics in a cartridge and cartridge module of limited size, various procedures can be performed with a single cartridge, and convenience and efficiency of the procedure can be improved. The size and shape of the transducers (340) and transducer housings (330) can be changed or miniaturized to allow multiple units to be arranged in the cartridge module, and space efficiency can be increased to solve the problems of increased volume and weight, and tight fit of the high-intensity focused ultrasound device including the cartridge.

[0139] The high-intensity focused ultrasound device of the present embodiment can perform various procedures by detachably coupling various types of transducer housings (330) to the cartridge module. The cartridge may be equipped with various types of transducers having specific frequencies and penetration depths, and the convenience and efficiency of performing various procedures can be improved by using a single cartridge without the need to replace the cartridge for each procedure.

[0140] FIG. 13 is a schematic diagram illustrating one embodiment of the transducer housing of the cartridge module of FIG. 10.

[0141] Referring to FIG. 13, a plurality of transducer housings (430a, 430b, 430c) may have the same fastening structure. The user can combine the transducer housings (430) in various ways according to the purpose of the procedure and can attach and detach them to the housing plate (421) through the housing coupling part (443). Depending on the combination of the transducer housings (430), a user-customized cartridge can be manufactured so that various procedures can be performed using a single cartridge, and the speed and convenience of the procedure can be improved.

[0142] When multiple transducer housings (430a, 430b, 430c) are arranged, the procedure time can be shortened by the number of transducer housings (430). The transducers housed in the transducer housings (430) can form more thermal focus per unit time or per unit of procedure, and the procedure speed can be improved compared to a procedure using a single transducer.

[0143] Additionally, a transducer housing (430) equipped with transducers having different thicknesses and materials can be combined and operated simultaneously or partially to perform the procedure. Multiple transducers can irradiate ultrasound with different frequencies or skin penetration depths simultaneously or sequentially. By arranging multiple transducers with various characteristics required for the procedure, various procedures can be performed without exchanging cartridges, and convenience of the procedure can be improved.

[0144] Multiple transducer housings (430a, 430b, 430c) may be arranged at different positions within the cartridge, and the arrangement structure may vary depending on the intensity and depth of the ultrasound being irradiated, the treatment site, and the purpose. The number and arrangement of the transducer housings (430) are not limited to the structure shown in the drawing and can be changed as needed.

[0145] According to the present embodiment, the size and shape of the transducer and the transducer housing (430) can be changed or miniaturized to allow for the placement of multiple units, and space efficiency can be increased to solve the problems of increased volume and weight and tightness of the high-intensity focused ultrasound device including the cartridge.

[0146] FIG. 14 is a drawing illustrating a modified example of FIG. 13, and FIG. 15 is a cross-sectional view illustrating a cross- section of the transducer housing of FIG. 14.

[0147] Referring to FIGS. 14 and 15, the transducer (540) may be received and fixed in the transducer housing (530), and as an example, the transducer (540) may be formed of a ceramic-based material. The transducer (540) may be sealed and coupled to the transducer housing (530) for waterproofing and may be electrically connected to a PCB (541) mounted on the top of the transducer housing (530).

[0148] At this time, the heights of the multiple transducer housings (530a, 530b, 530c) may be the same or different. The transducer (540) is housed in the transducer housing (530) having the same or different heights and can irradiate focused ultrasound having the same or different focal lengths. By changing the height of the transducer housing (530), the focal length of the ultrasound penetrating the skin can be controlled, and a precise and accurate procedure can be performed on a specific desired layer.

[0149] Even if the thickness and material of the transducer (540) housed in the transducer housing (530) are the same and the focal length is the same, the focal length to the skin surface may differ depending on the height of the transducer housing (530). For example, if the height of the transducer housing (530) increases, the depth of the ultrasound procedure may become deeper, and if the height decreases, the depth of the ultrasound procedure may become shallower.

[0150] Through a transducer housing (530) having different heights, treatment can be performed simultaneously on skin layers with different treatment depths, for example, treatment can be performed simultaneously on shallow and deep layers under the skin. As a specific example, ultrasound can be applied simultaneously to multiple skin layers, such as the epidermis and dermis, the epidermis and fascia, or the dermis and fascia, thereby shortening treatment time and improving treatment efficiency.

[0151] The high-intensity focused ultrasound device according to the present modification combines transducer housings (530) of different heights and arranges multiple transducer housings (530) in a single cartridge module, thereby enabling easy irradiation of skin layers at different depths simultaneously or at different times. Additionally, complex components for controlling ultrasound depth can be reduced or eliminated, allowing for the easy implementation of a compact and lightweight type of high-intensity focused ultrasound device. Furthermore, by controlling various ultrasound depths differently without exchanging cartridges, the convenience of the procedure and the effect of reducing the procedure time can be enhanced.

[0152] The high-intensity focused ultrasound device according to the present modification combines transducer housings (530) having various heights and attaches them to a housing plate (521) via a housing coupling part (543), thereby adjusting the distance at which the cartridge module is separated from the skin surface and providing a focal length having characteristics optimized for the procedure. At this time, the height of the transducer housing (530) can be determined by considering the focal length generated by the transducer (540), the purpose of the procedure, and safety. For example, the height of the transducer housing (530) can be determined so that the ultrasound irradiation depth is 1.5 mm to 4.5 mm.

[0153] When transducer housings (530) of various heights are mixed, if the height of some transducer housings (530) is below a certain height, a problem may occur in which the ultrasound emitted from the transducer (540) is not focused to the skin. Conversely, if the height of some transducer housings (530) exceeds a certain height, difficulty may occur in the cartridge module and the lower surface of the cartridge adhering to the skin.

[0154] Accordingly, this embodiment can provide a high-intensity focused ultrasound device with improved convenience and safety for the procedure by controlling the height of the transducer housing (530) so that ultrasound optimized for the procedure can be irradiated.

[0155] Meanwhile, the focused ultrasound generated by the multiple transducers (540) may be the same or different. For example, the characteristics of the focused ultrasound may vary depending on the thickness, material, etc. of the transducer (540), and the characteristics of the focused ultrasound may include the driving frequency and the distance at which the focus is formed during the procedure. By having the multiple transducers (540) output ultrasound with various characteristics, procedures using ultrasound of various frequencies and skin penetration depths can be performed without the hassle of replacing cartridges.

[0156] In one embodiment, a high-intensity focused ultrasound device includes a cartridge board, and a plurality of transducers (540) can be controlled individually. For example, a high-frequency generator (RF generator) may be connected to each of the plurality of transducers (540), and the cartridge board may control the transducers (540) to operate simultaneously or partially by distributing the high frequency generated from the high-frequency generator to each of the plurality of transducers (540).

[0157] This allows for a reduction in the cost required to manufacture a transducer (540) with matching frequency and impedance, and reduces the probability of failure caused by mismatch between the circuit and the transducer. Additionally, the transducer (540) does not need to receive control signals sequentially or through a switching circuit, thereby simplifying the circuit. By controlling the transducers (540) individually, transducers (540) with different characteristics can be placed in a single cartridge while ensuring fast operation and response speed.

[0158] Multiple transducers (540) and transducer housings (530) may be arranged at different positions within the cartridge, and the arrangement structure may vary depending on the intensity and depth of the ultrasound being irradiated, the treatment site, and the purpose. Additionally, the number and arrangement of transducer housings (530) are not limited to the structure shown in the drawing and can be changed as needed.

[0159] FIG. 16 is a diagram illustrating a modified example of the array structure of a transducer housing of a high-intensity focused ultrasound device.

[0160] Referring to FIG. 16, the high-intensity focused ultrasound device may include a plurality of transducer housings. Although not illustrated, the ultrasound device of the present embodiment may include a main body and a cartridge, and the main body and cartridge may be applied in various forms, for example, the main body and cartridge module of the above-described embodiment may be applied.

[0161] Multiple transducer housings may be arranged in a cartridge module to have various arrangement structures. For example, the transducer housings may have a serial arrangement structure in which they are arranged in a line along the same direction as the movement direction of the moving part that slides along a moving rail. As another example, the transducer housings may be arranged in a line along a direction different from the movement direction of the moving part, specifically, they may have a parallel arrangement structure in which they are arranged in a line along a direction perpendicular to the movement direction of the moving part. Additionally, the transducer housings may be arranged in a mixed arrangement along the same or different directions as the movement direction of the moving part.

[0162] The transducer housing can have various arrangement structures by changing the position of the housing plate and can provide various cartridges suitable for the procedure. Users can manufacture customized cartridges by replacing, exchanging, or removing the positioned transducer housing according to the scope and purpose of the procedure. Since the position and interval of ultrasound irradiation can be changed, cartridge replacement can be minimized, and the speed and convenience of the procedure can be improved by simultaneously irradiating ultrasound with the same or different frequencies and penetration depths.

[0163] In addition, the transducer housing can be rotated. By changing the angles of the housing plate and the transducer housing and rotating them, the position and spacing of the output focused ultrasound can be changed, and the precision of the procedure can be improved.

[0164] The spacing between the focal points of the focused ultrasound generated by the transducer can be adjusted according to the rotation angle of the transducer housing. In this case, the rotation angle of the transducer housing can be determined by comprehensively considering the diameter of the focal points generated by the transducer, the distance between focal points, the purpose of the procedure, safety, the size and location of the target, and the tissue condition.

[0165] For example, if the focal interval exceeds a certain interval, the distance between the ultrasound waves irradiated onto the skin widens, which can significantly reduce the effectiveness of the treatment. Conversely, if the focal interval falls short of a certain interval, overlapping ultrasound waves are excessively irradiated, which can cause skin damage.

[0166] That is, a high-intensity focused ultrasound device can be provided that can maximize the treatment effect without causing damage by forming a dense thermal focus by rotating or arranging multiple transducer housings in various ways.

[0167] In one embodiment, the height of the placed transducer housing may be the same or different. Additionally, the thickness and material of the transducer housed in the placed transducer housing may be the same or different, and the ultrasound output by the transducer may be the same or different.

[0168] In addition, by changing or miniaturizing the size and shape of the transducer and transducer housing, multiple units can be placed in the cartridge module, and by increasing space efficiency, the problems of increased volume and weight, as well as close contact, of the high-intensity focused ultrasound device including the cartridge can be resolved. By placing multiple transducers with characteristics suitable for the type, site, and purpose of the procedure in a single cartridge, ultrasound of various characteristics can be output without exchanging the cartridge, allowing the procedure to be performed efficiently.

[0169] In addition to this, multiple transducer housings may have various arrangement structures. The shape and arrangement structure of the transducer housings, including the size, height, and number of the transducer housings, are not limited to those depicted in the drawings above, and the transducer housings may have various arrangement structures as long as they can be coupled to a cartridge module to provide the same or different frequencies and penetration depths.

[0170] FIG. 17 is a drawing illustrating another example of a cartridge module, FIG. 18 is a perspective view of the module housing of FIG. 17, FIG. 19 is a view of the module housing of FIG. 18 from the left, FIG. 20 is a view of the module housing of FIG. 18 from the right, FIG. 21 is a view of the module housing of FIG. 18 from the front, and FIG. 22 is a view of the module housing of FIG. 18 from the rear.

[0171] Referring to FIGS. 17 through 22, the cartridge module (6100) may be placed in a region inside the cartridge. The cartridge module (6100) may include a module housing (6120), a drive shaft (6130), a moving part (6140), and a transducer (6161).

[0172] The module housing (6120) may be intended to structurally support the cartridge module (6100) or to protect internal components contained in the cartridge module (6100). The module housing (6120) may provide a support surface or a receiving space so that the drive shaft (6130), the moving part (6140), and the transducer (6161) can be stably positioned within the cartridge internal space. The module housing (6120) may be formed as a single unit or may be in the form of multiple combined members.

[0173] The drive shaft (6130) can guide the movement path of the transducer (6161). In one embodiment, one end of the drive shaft (6130) can be connected to a motor (6190). The drive shaft (6130) can transmit the driving force of the motor (6190) to other parts of the ultrasonic device, and, for example, the moving part (6140) and the transducer housing (6160) can move by receiving power from the drive shaft (6130).

[0174] The moving part (6140) can connect the drive shaft (6130) and the transducer housing (6160). One side of the moving part (6140) can be connected to the drive shaft (6130), and the other side can be connected to the transducer housing (6160). The moving part (6140) can receive power from the drive shaft (6130), and specifically, can move by receiving the driving force of the motor (6190).

[0175] In one embodiment, the moving part (6140) can move linearly along the longitudinal direction of the drive shaft (6130). The transducer housing (6160) coupled with the moving part (6140) can move together with the movement of the moving part (6140). The transducer (6161) housed in the transducer housing (6160) can move together with the movement of the transducer housing (6160). The transducer (6161) can have various treatment ranges depending on the range of motion of the moving part (6140), and the range in which ultrasound is irradiated can be adjusted according to the type of treatment, target size, shape, frequency of ultrasound, skin penetration depth, etc.

[0176] In one embodiment, the transducer (6161) may include a concave shape facing toward the skin surface. The transducer (6161) can form a thermal focus to focus ultrasound to a spaced-apart location.

[0177] The transducer housing (6160) can accommodate a transducer (6161). The transducer housing (6160) may have a curvature corresponding to the transducer (6161) having a concave shape. The transducer housing (6160) may be positioned to face the treatment target. Specifically, the transducer housing (6160) may face the lower part of the cartridge to output ultrasound to the outside of the ultrasound device. The transducer (6161) is positioned within the transducer housing (6160) to perform the treatment by focusing and irradiating ultrasound toward the skin surface.

[0178] In one embodiment, one end of the moving part (6140) may be connected to a housing plate (6150). At least one transducer housing (6160) may be disposed on the housing plate (6150). The transducer housing (6160) and the housing plate (6150) may be joined in various ways, such as by protrusion fastening, fitting, interlocking, or bolt connection.

[0179] In one embodiment, the transducer housing (6160) may be detachable from the housing plate (6150). The transducer housing (6160) may be separated from the moving part (6140) via the housing plate (6150) without damaging the parts. The user may detach the transducer housing (6160) coupled to the housing plate (6150) and select and replace the transducer (6161) required for the procedure. A detailed explanation thereof will be provided later.

[0180] In one embodiment, the module housing (6120) may include a first housing (6121), a second housing (6122), and a third housing (6123). The second housing (6122) may be opposite to the first housing (6121). The third housing (6123) may be arranged in a direction intersecting the first housing (6121) and the second housing (6122).

[0181] The drive shaft (6130) may be positioned between the first housing (6121) and the second housing (6122). The moving part (6140) is coupled to the drive shaft (6130) and may move between the first housing (6121) and the second housing (6122). The distance between the first housing (6121) and the second housing (6122) may be the range of movement of the transducer (6161) and may be the range of treatment where ultrasound is irradiated from the high-intensity focused ultrasound device.

[0182] The positions of the first housing (6121) and the second housing (6122) can define the starting and ending points of the movement path of the moving part (6140), and the distance between the first housing (6121) and the second housing (6122) can be the treatment area and treatment range where ultrasound is irradiated. For example, the position of the first housing (6121) can be the maximum forward position of the transducer (6161), and the position of the second housing (6122) can be the maximum backward position of the transducer (6161). The transducer (6161) can have various treatment ranges depending on the distance between the first housing (6121) and the second housing (6122), and the treatment range can be adjusted according to the type of treatment, target size, shape, frequency, skin penetration depth, etc.

[0183] In one embodiment, the first housing (6121) and the second housing (6122) can each be coupled to both ends of the drive shaft (6130). The first housing (6121) and the second housing (6122) can structurally support the drive shaft (6130) so that the drive shaft (6130) does not bend or twist. The drive shaft (6130) can be fixed by the housings facing each other to maintain a stable alignment state. The drive shaft (6130) can be constrained by the first housing (6121) and the second housing (6122) to maintain stable axis alignment and provide a linear motion path for the moving part (6140). Through this, vibrations caused by the repetitive movement of the moving part (6140), deformation, damage, and wear of the drive shaft (6130) can be reduced, and the accuracy of the procedure can be improved by maintaining the focal position precisely. The coupling structure of the drive shaft (6130) and the module housing (6120) can be varied, for example, the drive shaft (6130) and the first housing (6121) and the second housing (6122) can be coupled through a snap coupling, a screw coupling, etc.

[0184] In one embodiment, the first housing (6121) and the second housing (6122) may each include a first penetration (6131) formed to allow at least one region of the drive shaft (6130) to pass through. The first penetration (6131) may be an opening formed to allow the drive shaft (6130) to pass through the module housing (6120). The drive shaft (6130) may be inserted into the first penetration (6131) and positioned between the first housing (6121) and the second housing (6122).

[0185] The first penetration (6131) can be implemented in various shapes and can be formed in a shape corresponding to the outer shape of the drive shaft (6130). For example, the first penetration (6131) may include a circular opening formed to correspond to the column-shaped drive shaft (6130).

[0186] The first penetration part (6131) can uniformly wrap around and support the surface of the drive shaft (6130) and reduce the stress concentrated on the drive shaft (6130). The load acting on the drive shaft (6130) can be transmitted to and distributed to the module housing (6120) through the first penetration part (6131). Through this, the detachment, vibration, and eccentricity of the drive shaft (6130) are effectively suppressed, and focus stability and surgical precision can be improved.

[0187] In one embodiment, the cartridge module (6100) may include a transfer member (6170) positioned parallel to the drive shaft (6130). The transfer member (6170) may assist in the movement of the moving part (6140). The transfer member (6170) may be positioned between the drive shaft (6130) and the transducer housing (6160) to support a portion of the load of the moving part (6140). The transfer member (6170) may guide the movement path of the moving part (6140) which moves linearly back and forth together with the drive shaft (6130). For example, the transfer member (6170) may be a column-shaped auxiliary shaft, and the moving part (6140) may move back and forth sliding along the longitudinal direction of the drive shaft (6130) and the transfer member (6170). The transfer member (6170) may be a cylindrical support member made of stainless steel.

[0188] In one embodiment, the transfer member (6170) may be positioned between the first housing (6121) and the second housing (6122). One end of the transfer member (6170) may be connected to the first housing (6121), and the other end may be connected to the second housing (6122). The first housing (6121) and the second housing (6122) may structurally support the transfer member (6170) so that the transfer member (6170) does not bend or twist. The transfer member (6170) may be fixed by the housings facing each other to stably maintain an alignment state. The transfer member (6170) may be restrained by the first housing (6121) and the second housing (6122) and may suppress shaking or rotation that occurs during the movement of the moving part (6140). The coupling structure of the carrier (6170) and the module housing (6120) can be varied, for example, the carrier (6170), the first housing (6121), and the second housing (6122) can be coupled through a snap coupling, a screw coupling, etc.

[0189] In one embodiment, the first housing (6121) and the second housing (6122) may each include a second penetration (6171) formed to allow at least one area of ​​the carrier (6170) to pass through. The second penetration (6171) may be an opening formed to allow the carrier (6170) to pass through the module housing (6120). The carrier (6170) may be inserted into the second penetration (6171) and positioned between the first housing (6121) and the second housing (6122). The second penetration (6171) may be implemented in various shapes and may be formed in a shape corresponding to the external shape of the carrier (6170). For example, the second penetration (6171) may include a circular opening formed to correspond to a column-shaped carrier (6170).

[0190] The second penetration part (6171) can uniformly wrap around and support the surface of the transfer member (6170) and reduce the stress concentrated on the transfer member (6170). The load acting on the transfer member (6170) can be transmitted to and distributed to the module housing (6120) through the second penetration part (6171). Through this, the detachment, vibration, and eccentricity of the transfer member (6170) are effectively suppressed, and focus stability and surgical precision can be improved.

[0192] The third housing (6123) may be positioned in a direction intersecting the first housing (6121) and the second housing (6122). For example, the third housing (6123) may be positioned in a direction perpendicular to the first housing (6121) and the second housing (6122).

[0193] In one embodiment, the third housing (6123) may be positioned to be in contact with at least a portion of the first housing (6121) and the second housing (6122).

The cartridge module (6100) can be secured at various locations inside the cartridge, such as the upper, lower, and side portions.

[0197] In one embodiment, the cartridge module (6100) may be detachable from the cartridge. The user can easily separate the cartridge module (6100) from the cartridge by releasing the coupling structure of the coupling part (6124). This allows for inspection and repair of the cartridge module (6100) without disassembling the entire ultrasonic device, and enables the rapid replacement of a damaged or degraded cartridge module (6100).

[0198] As a specific example, the third housing (6123) may be positioned above the cartridge based on the direction in which the cartridge is mounted on the main body, and the coupling part (6124) may be positioned in the third housing (6123) to secure the cartridge module (6100) to the upper inner surface of the cartridge. The user can easily assemble or disassemble the cartridge module (6100) through the coupling part (6124) positioned in the third housing (6123), and the convenience of maintenance and replacement of the cartridge module (6100) can be improved.

[0199] The drawing illustrates an embodiment in which a screw fastening coupling hole is formed in the third housing (6123) as an example of a coupling part (6124), but the method of coupling between the cartridge module (6100) and the cartridge and the location of the coupling part (6124) are not limited thereto.

For example, the second fixing member (7173) may be disposed on the inner surface where the first housing (7121) and the second housing (7122) face each other, or on the outer surface of each housing.

[0205] The second fixing member (7173) can restrict the axial movement of the carrier (7170) near the second penetration part (7171) and stably support the carrier (7170). As an example, the second fixing member (7173) may be a fixing ring mounted in the joint area between the carrier (7170) and the second penetration part (7171). The fixing ring may be fastened or fitted into a fixing groove formed on the outer surface of the carrier (7170) to prevent the carrier (7170) from coming off.

[0206] In one embodiment, the coupling part (7124) may be disposed in the third housing (7123). The third housing (7123) may be disposed on the upper side of the cartridge opposite to the lower side of the cartridge where the ultrasound is output. The coupling part (7124) can fix the cartridge module (7100) to the upper inner surface of the cartridge. The coupling part (7124) can stably fix the cartridge module (7100) inside the cartridge without interfering with the movement of the moving part (7140) or the ultrasonic irradiation of the transducer (7161).

[0207] The third housing (7123) may be positioned in a direction intersecting the first housing (7121) and the second housing (7122), for example, in a direction perpendicular to the first housing (7121) and the second housing (7122).

The protruding area may provide an area where the third housing (7123) and the cartridge can be coupled. For example, the coupling portion (7124) may be placed in the protruding area of ​​the third housing (7123) to stably secure the cartridge module (7100) inside the cartridge without hindering the movement of the drive shaft (7130) and the moving portion (7140).

[0209] FIG. 26 is a drawing showing a part of a cartridge module, and FIG. 27 is an enlarged drawing of a part of the moving part of FIG. 26.

[0210] Referring to FIGS. 26 and 27, the moving part (1340) may include a first hole (1341) and a second hole (1342).

[0211] In one embodiment, the first hole (1341) may be an opening formed so that the drive shaft (1330) can pass through the moving part (1340). The drive shaft (1330) may be inserted and fitted into the first hole (1341), and the moving part (1340) may come into contact with the drive shaft (1330) through the inner surface of the first hole (1341).

[0212] The moving part (1340) can uniformly wrap around and support the surface of the drive shaft (1330) through the first hole (1341). The first hole (1341) can increase the contact area with the drive shaft (1330), and the moving part (1340) can move stably along the longitudinal direction of the drive shaft (1330) without shaking or detaching.

[0213] The first hole (1341) can stably support the drive shaft (1330) by increasing the contact area with the surface of the drive shaft (1330), for example, the thread (1331) of the drive shaft (1330), and the backlash of the motor is reduced, thereby increasing the movement of the moving part (1340) and the precision of the procedure of the ultrasonic device.

[0214] In one embodiment, the drive shaft (1330) may include a screw thread (1331) arranged along its outer surface, and may include a screw groove (1332) formed on the inner surface of the first hole (1341) that corresponds to the screw thread (1331) of the drive shaft (1330). One end of the drive shaft (1330) may be connected to a motor, and the motor may rotate the drive shaft (1330) to drive the moving part (1340). The screw thread (1331) may be coupled with the screw groove (1332), and the rotational force of the motor may be converted into linear motion of the moving part (1340) along the drive shaft (1330) and transmitted. Through this, the moving part (1340) and the drive shaft (1330) can be stably coupled, and the moving part (1340) can maintain a constant movement path, thereby improving the precision of the focus position and irradiation direction of the ultrasound.

[0215] In one embodiment, the second hole (1342) may be an opening formed to allow the carrier (1370) to pass through the moving part (1340). The carrier (1370) may be inserted and fitted into the second hole (1342), and the moving part (1340) may come into contact with the carrier (1370) through the inner surface of the second hole (1342). The second hole (1342) may be implemented in various shapes and may be formed in a shape corresponding to the outer shape of the carrier (1370). For example, the second hole (1342) may include a circular opening formed to correspond to a column-shaped carrier (1370).

[0216] The moving part (1340) can uniformly wrap around and support the surface of the carrier (1370) through the second hole (1342). The second hole (1342) can increase the contact area with the carrier (1370), and the moving part (1340) can move stably along the longitudinal direction of the carrier (1370) without shaking or detaching.

[0217] The moving part (1340) can move linearly along the drive shaft (1330), and the housing plate (1350) and transducer housing (1360) connected to the moving part (1340) can move together with the moving part (1340).

[0218] A plurality of transducer housings (1360) may be disposed on the housing plate (1350). The transducer housings (1360) may have various arrangement structures, and, for example, the aforementioned embodiments or variations may be applied within the same or similar range, and a specific description thereof is omitted.

[0219] A method for manufacturing a high-intensity focused ultrasound device according to one embodiment of the present invention may include the steps of preparing a main body formed to transmit and receive electrical signals, preparing a cartridge including a cartridge module, arranging the cartridge to be connected to the main body, and combining the cartridge and the main body. For convenience of explanation, the following description will be explained with reference to FIGS. 17 and 18.

[0220] The step of preparing the main body may be a step of preparing a main body having an internal space capable of accommodating a connector and other electrical components connected to a motor (6190), a transducer (6161), a sensor, etc.

[0221] The step of preparing the cartridge may be a step of preparing a cartridge equipped with a cartridge module (6100) including a transducer (6161).

[0222] The step of combining the cartridge and the main body may be a step of electrically connecting the cartridge and the main body by mounting the cartridge onto the main body. For example, the terminal portion of the cartridge may be connected to the electrode of the main body to transmit and receive electrical signals for controlling the oscillation of ultrasound.

[0223] The main body can control the oscillation of ultrasound by transmitting and receiving electrical signals, and the cartridge module (6100) may include a module housing (6120), a drive shaft (6130), a transducer (6161), and a moving part (6140), which is identical or similar to the above-described embodiment, so a specific description thereof is omitted.

[0224] As an embodiment, the step of preparing a cartridge may include the step of placing the cartridge module (6100) in a region inside the cartridge so that the cartridge module (6100) faces the treatment target. The cartridge module (6100) may be placed in the cartridge so that the transducer (6161) faces the treatment target.

[0225] In one embodiment, the module housing (6120) may include a coupling part (6124) that secures the cartridge module (6100) to a part of the cartridge.

[0226] The cartridge module (6100) can be inserted into the cartridge in an externally combined or assembled state, and can be fixed inside the cartridge through the coupling part (6124). This simplifies the cartridge manufacturing process and improves the alignment accuracy of the cartridge module (6100) within the cartridge. For example, a user can insert a module housing (6120) combined with a drive shaft (6130), a moving part (6140), a transducer (6161), etc. into the cartridge and assemble it to stably place the cartridge module (6100) inside the cartridge.

[0227] The coupling portion (6124) can implement various coupling structures between the cartridge module (6100) and the cartridge. For example, the coupling portion (6124) can secure the cartridge module (6100) to the cartridge through various coupling methods such as protrusion fastening, insertion, interlocking, and bolt connection. The cartridge module (6100) can be secured at various locations inside the cartridge, such as the upper, lower, and side portions.

[0228] In one embodiment, the cartridge module (6100) may be detachable from the cartridge. The user can easily separate the cartridge module (6100) from the cartridge by releasing the coupling structure of the coupling part (6124). This allows for inspection and repair of the cartridge module (6100) without disassembling the entire ultrasonic device, and enables the rapid replacement of a damaged or degraded cartridge module (6100).

[0229] The cartridge module (6100) can be easily fixed inside the cartridge through the coupling part (6124), and the cartridge module (6100) can be fixed in an accurate position even in a complex internal structure including, for example, a plurality of sensors or transducers (6161).

[0230] The cartridge module (6100) can be positioned at a fixed location to reduce interference between the moving part (6140), the transducer (6161), and other internal parts, and can precisely maintain the movement path of the moving part (6140) and the ultrasonic irradiation direction of the transducer (6161).

[0231] The module housing (6120) of the cartridge module (6100) may be formed as a single unit or may be in the form of multiple combined members. Additionally, members such as the drive shaft (6130), moving part (6140), and transporter (6170) may be combined with the module housing (6120) or other members in various ways, and may be assembled, for example, through bonding, screws, fittings, penetrations, fastening members, etc. The user can easily manufacture an ultrasonic device by inserting and combining the cartridge module (6100), in which each member is assembled, into a cartridge in module units.

[0232] The manufacturing method of the present embodiment can save time required for internal joining processes, such as bonding processes for joining between each component, and improve the precision of the mechanism assembly, thereby improving the productivity of the manufacturing process of the cartridge module (6100) and the ultrasonic device. Through the joining part (6124), the cartridge module (6100) can be easily disassembled from the cartridge or assembled inside the cartridge, and the convenience of maintenance and replacement of the cartridge module (6100) can be improved.

[0233] FIG. 28 is a flowchart illustrating a method for controlling a high-intensity focused ultrasound device according to one embodiment of the present invention.

[0234] Referring to FIG. 28, 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).

[0235] 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.

[0236] 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.

[0237] 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.

[0238] 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.

[0239] 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.

[0240] 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.

[0241] 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.

[0242] 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.

[0243] 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.

[0244] 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.

[0245] 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.

[0246] FIG. 29 is a flowchart illustrating a variation of FIG. 28.

[0247] Referring to FIG. 29, the control signal supply step (S10) may include a high frequency generation step (S11).

[0248] 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.

[0249] 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.

[0250] 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.

[0251] 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.

[0252] 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.

[0253] 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).

[0254] As such, the present invention has been described with reference to the embodiments illustrated in the drawings, but this is merely illustrative, and those skilled in the art will understand that various modifications and equivalent alternative embodiments are possible therefrom. Accordingly, the true technical scope of protection of the present invention should be determined by the technical spirit of the appended claims.
