Description

Technical Field

[0001] The present disclosure relates to a cartridge for an ultrasonic irradiation device and a method thereof.

Background Art

[0002] Ultrasound means a wave having a frequency of 20 kHz or more and has the property of transmitting through water, so it is widely used in the medical field such as ultrasonic diagnostic devices and ultrasonic irradiation devices.

[0003] The utilization of ultrasound in the medical field is most typically represented by an ultrasonic imaging device that utilizes the properties of ultrasound to transmit and reflect. For example, there is a device that visualizes the time and intensity of reflection while ultrasound penetrates the human body and each organ to obtain a cross-sectional image of the human body.

[0004] In addition, there is a device that uses the heat generated by high-intensity focused ultrasound (HIFU) to burn and remove specific subcutaneous tissues such as tumors in the skin, or to induce degeneration and regeneration of skin tissues to produce effects such as skin beautification or skin shaping for wrinkle improvement.

[0005] In a conventional ultrasonic irradiation device, irradiation is performed with the transducer immersed in distilled water so that the transducer is not struck.

[0006] However, in the case of variations such as the evaporation state, remaining amount, and inclination state of distilled water, a conventional ultrasonic irradiation device has limitations in efficiently irradiating ultrasound, limitations in extending the life of the transducer, and limitations in preventing accidents caused by ultrasonic irradiation.

[0039] The operating principle and embodiments of this disclosure will be described below with reference to the attached drawings.

[0040] First, High-Intensity Focused Ultrasound (HIFU) technology uses the heat generated when high-intensity ultrasound is focused on a single point within the skin to burn specific subcutaneous tissues, such as tumors.

[0041] This works on a principle similar to using a magnifying glass to focus sunlight and start a fire. Because ultrasound easily penetrates body tissue, HIFU irradiation is performed in a completely non-invasive manner without the need for scalpels or needles. In other words, it is a method that burns and irradiates specific subcutaneous tissue, such as tumors, simply by bringing the patient's skin into close contact with the ultrasound generating surface. In addition to this, HIFU irradiation is currently being used for uterine fibroids, bone metastases, prostate cancer, breast cancer, pancreatic cancer, liver cancer, kidney cancer, and more.

[0042] This type of high-intensity focused ultrasound irradiation can be achieved using an ultrasound irradiation device. The ultrasound irradiation device can deliver ultrasound waves to the surface of the patient's skin.

[0056] Processor 122 is, Measuring instrument Connected to 110, and based on the measured impedance of the fluid, the corresponding ultrasonic energy, which has already been set according to the evaporation state of the fluid, is applied. Ultrasonic irradiator 130 can be controlled. Also, when at least one of the housing and handpiece is positioned within a pre-set irradiation limit angle according to the remaining amount of fluid, the processor 122 applies ultrasound corresponding to the irradiation limit angle. Ultrasonic irradiator It can also control 130. Furthermore, the processor 122 applies ultrasound corresponding to the irradiation limit angle when at least one of the housing and handpiece is positioned within a pre-set irradiation limit angle depending on the tilt angle. Ultrasonic irradiator It can also control 130. Furthermore, the processor 122 applies ultrasonic waves corresponding to the irradiation limit angle when at least one of the housing and handpiece is positioned within a pre-set irradiation limit angle according to the fluid level and inclination level.

[0057] Figure 2 is a flowchart illustrating an example of the ultrasonic wave generation method according to this disclosure. Figure 3 is a diagram illustrating an example of the process of measuring fluid impedance using the measurement steps in Figure 2.

[0058] As shown in Figures 2 and 3, the ultrasonic generation method may include a measurement step (S210) and a control step (S220).

[0059] The measurement steps are: Measuring instrument The impedance of the fluid L can be measured via 110 (S210). Here, Measuring instrument 110 is electrically connected to the PCB provided on the processor 122 and may include two impedance terminals 111a, 111b to measure the impedance of the fluid L. In this case, the housing 101 is Ultrasonic irradiator The transducer 131 can be configured to be immersed in the fluid L.

[0060] The control phase involves, via the processor 122, determining the evaporation state of the fluid L based on the measured impedance of the fluid L, determining the presence or absence of fluid in the transducer 131 based on the evaporation state, and, if fluid is present, applying ultrasonic energy. Ultrasonic irradiator It can control 130 (S220). On the other hand, processor 122 does not apply ultrasonic energy when no fluid is present. Ultrasonic irradiator The 130 can be controlled, and the notification means can also be controlled to indicate the absence of fluid via at least one of the notification means, an audio speaker and an LED.

[0061] Figure 4 is a flowchart illustrating another example of the ultrasonic generation method according to this disclosure. Figure 5 is a diagram illustrating, as an example, the process of setting the irradiation limit angle based on the fluid impedance at different depths using the measurement and control steps of Figure 4.

[0062] As shown in Figures 4 and 5, the ultrasonic generation method may include a measurement step (S410) and a control step (S420).

[0063] The measurement steps are: Measuring instrument The impedance can also be measured separately for each depth of the fluid L via 110 (S410). Here, Measuring instrument 110 is electrically connected to the PCB provided on the processor 122 and may include four impedance terminals 111c to 111f to measure impedance at different depths of fluid L. Measuring instrument 110 is electrically connected to the PCB provided on the processor 122 and may include a separate impedance terminal 111g to measure the impedance of the air layer A. In this case, the number of impedance terminals is not limited to five, and may be less than five or six or more.

[0064] The control phase determines the remaining amount of fluid L via the processor 122 based on at least one of the measured depth-specific impedances of the fluid L and the measured impedance of the air layer A, and applies ultrasonic waves corresponding to the irradiation limit angle when at least one of the housing 101 and the handpiece coupled to the housing 101 is positioned within the irradiation limit angle already set according to the remaining amount of fluid L. Ultrasonic irradiator It can also control 130 (S420).

[0065] For example, the processor 122 applies ultrasound corresponding to the first irradiation limit angle when the remaining amount of fluid L, determined by measurement of five impedance terminals 111c to 111g, is a pre-set first reference amount, and at least one of the housing 101 and the handpiece is located within a pre-set first irradiation limit angle according to the first reference amount. Ultrasonic irradiator It can control 130. Here, Ultrasonic irradiator 130 can irradiate the skin with ultrasound corresponding to the first irradiation limiting angle. At this time, the first irradiation limiting angle θ1 can be within a range where irradiation is possible up to 240°. Here, the processor 122 applies the ultrasound energy in steps to a previously set intensity. Ultrasonic irradiator It is also possible to control 130. In this case, the already set intensity can be at least one of the following: weak intensity, medium intensity, or strong intensity.

[0066] As another example, the processor 122 applies ultrasound corresponding to the second irradiation limit angle when the remaining amount of fluid L, as determined by measurements of the four impedance terminals 111c to 111f, is less than a first reference amount already set, and at least one of the housing 101 and the handpiece is located within a second irradiation limit angle already set according to the second reference amount. Ultrasonic irradiator It can control 130. Here, Ultrasonic irradiator130 can irradiate the skin with ultrasound corresponding to the second irradiation limiting angle. In this case, the second irradiation limiting angle θ2 can be within a range where irradiation is possible up to 180°. Here, the processor 122 applies the ultrasound energy in steps to a previously set intensity. Ultrasonic irradiator It is also possible to control 130. In this case, the already set intensity can be at least one of the following: weak intensity, medium intensity, or strong intensity.

[0067] As yet another example, the processor 122 applies ultrasound corresponding to the third irradiation limit angle when the remaining amount of fluid L, as determined by measurements of the three impedance terminals 111d~111f, is less than a already set second reference amount, and at least one of the housing 101 and the handpiece is located within a third irradiation limit angle already set according to the third reference amount. Ultrasonic irradiator It can control 130. Here, Ultrasonic irradiator 130 can irradiate the skin with ultrasound corresponding to the third irradiation limit angle. In this case, the third irradiation limit angle θ3 can be within a range where irradiation is possible up to 150°. Here, the processor 122 applies the ultrasound energy in steps to a previously set intensity. Ultrasonic irradiator It is also possible to control 130. In this case, the already set intensity can be at least one of the following: weak intensity, medium intensity, or strong intensity.

[0068] As another example, the processor 122 applies ultrasound corresponding to the fourth irradiation limit angle when the remaining amount of fluid L, as determined by measurements of two impedance terminals 111e and 111f, is less than a third reference amount already set, and at least one of the housing 101 and the handpiece is located within a fourth irradiation limit angle already set according to the fourth reference amount. Ultrasonic irradiator It can control 130. Here, Ultrasonic irradiator130 can irradiate the skin with ultrasound corresponding to the fourth irradiation limit angle. In this case, the fourth irradiation limit angle θ4 may be within a range where irradiation is possible up to 120°. Here, the processor 122 applies the ultrasound energy in steps to a previously set intensity. Ultrasonic irradiator It is also possible to control 130. In this case, the already set intensity can be at least one of the following: weak intensity, medium intensity, or strong intensity.

[0069] As yet another example, the processor 122 applies ultrasound corresponding to the fifth irradiation limit angle when the remaining amount of fluid L, as determined by measurement of one impedance terminal 111f, is less than a already set fourth reference amount, and at least one of the housing 101 and the handpiece is located within a fifth irradiation limit angle already set according to the fifth reference amount. Ultrasonic irradiator It can control 130. Here, Ultrasonic irradiator 130 can irradiate the skin with ultrasound corresponding to the fifth irradiation limit angle. In this case, the fifth irradiation limit angle θ5 may be within a range where irradiation is possible up to 90°. Here, the processor 122 applies the ultrasound energy in steps to a previously set intensity. Ultrasonic irradiator It is also possible to control 130. In this case, the already set intensity can be at least one of the following: weak intensity, medium intensity, or strong intensity.

[0070] On the other hand, the irradiation limiting angle is not limited to five angle conditions, but can be set in various ways depending on four or fewer angle conditions or six or more angle conditions.

[0071] Figure 6 is a flowchart illustrating the ultrasonic generation method according to this disclosure as another example. Figures 7 to 9 illustrate, as an example, the process of measuring the inclination angle of at least one of the housing and handpiece using the measurement steps in Figure 6.

[0072] As shown in Figures 6 to 9, the ultrasonic generation method may include a measurement step (S610) and a control step (S620).

[0073] The measurement steps are: Measuring instrument The tilt angle of at least one of the housing 101 and the handpiece 102 coupled to the housing 101 can also be measured via 110 (S610). Here, Measuring instrument The 110 may include an inertial measurement unit (IMU) to measure the angle of inclination.

[0074] For example, the inertial measurement device may be at least one of a gyro sensor and an accelerometer 111h. Here, as shown in Figure 7, the accelerometer 111h can be mounted on a PCB(P), and as shown in Figure 8, the PCB(P) can be provided in at least one of the following locations: inside the handpiece 102 and inside the housing 101. In this case, the accelerometer 111h can sense the X, Y, and Z axis directions of the handpiece 102 and the X, Y, and Z axis directions of the housing 101.

[0075] As shown in Figure 9, the acceleration sensor 111h can acquire acceleration data in the X, Y, and Z directions according to the angular position of the handpiece 102.

[0076] For example, the acceleration sensor 111h can acquire acceleration data for directions 1 through 8 of the X-axis, acceleration data for directions 1 through 8 of the Y-axis, and acceleration data for directions 1 through 8 of the Z-axis.

[0077] The control phase, via the processor 122, applies ultrasound corresponding to the irradiation limit angle when at least one of the housing 101 and handpiece 102 is positioned within a pre-set irradiation limit angle depending on the tilt angle. Ultrasonic irradiator It can also control 130 (S620).

[0078] As an example, the processor 122 applies ultrasound corresponding to the sixth irradiation limit angle when at least one of the housing 101 and the handpiece 102 is positioned within a sixth irradiation limit angle that has already been set according to the tilt angle. Ultrasonic irradiator It can control 130. Here, Ultrasonic irradiator 130 can irradiate the skin with ultrasound corresponding to the sixth irradiation limit angle. In this case, the sixth irradiation limit angle may be a range in which irradiation is possible up to 240°, a range in which irradiation is possible up to 180°, a range in which irradiation is possible up to 150°, a range in which irradiation is possible up to 120°, or a range in which irradiation is possible up to 90°. Here, the processor 122 applies the ultrasound energy in steps to an already set intensity. Ultrasonic irradiator It is also possible to control 130. In this case, the already set intensity can be at least one of the following: weak intensity, medium intensity, or strong intensity.

[0079] For example, if the measured tilt angle is 180° and the sixth irradiation limit angle is set to a range up to 180°, the processor 122 will apply the already set ultrasound because the angle falls within the 180° range. Ultrasonic irradiator It can control 130.

[0080] As another example, if the measured tilt angle is 200° and the sixth irradiation limit angle is set to a range up to 240°, then the processor 122 will apply the already set ultrasound because the angle falls within the 240° range. Ultrasonic irradiator It can control 130.

[0081] As another example, if the measured tilt angle is 250° and the sixth irradiation limit angle is set to a range up to 240°, the processor 122 will not apply ultrasound because the angle is outside the 240° range. Ultrasonic irradiator It can control 130. On the other hand, the irradiation limiting angle is not limited to three angle conditions, but can be set in various ways according to two or fewer angle conditions or four or more angle conditions.

[0082] Figure 10 is a flowchart illustrating yet another example of the ultrasonic generation method according to this disclosure. Figures 11 to 13 illustrate, as an example, the process of measuring at least one of the distilled water level and inclination level according to the measurement steps in Figure 10.

[0083] As shown in Figures 11 to 13, the ultrasonic generation method may include a measurement step (S1110) and a control step (S1120).

[0084] The measurement steps are: Measuring instrument It is also possible to measure at least one of the fluid level and incline level of the fluid L via 110 (S1110). Here, Measuring instrument The 110 may include a plurality of water level sensors 111k1 to 111k10 of the same depth, provided on both sides inside the housing 101 to measure at least one of the water level and inclination level of the fluid L. Here, the plurality of water level sensors 111k1 to 111k10 of the same depth can be provided on both sides inside the housing 101 at equal intervals from each other. In this case, the number of the plurality of water level sensors of the same depth is not limited to 10, but may be 8 or less, or 12 or more.

[0085] For example, as shown in Figure 11, the first water level sensor 111k1 and the sixth water level sensor 111k6 can be installed in the same position on both sides of the upper interior of the housing 101, and the second water level sensor 111k2 and the seventh water level sensor 111k7 can be installed in the same position on both sides of the upper interior of the housing 101, and at a lower position than the first water level sensor 111k1 and the sixth water level sensor 111k6.

[0086] Furthermore, the third water level sensor 111k3 and the eighth water level sensor 111k8 can be provided at the same position on both sides of the upper interior of the housing 101, and can be provided at a lower position than the second water level sensor 111k2 and the seventh water level sensor 111k7. The fourth water level sensor 111k4 and the ninth water level sensor 111k9 can be provided at the same position on both sides of the upper interior of the housing 101, and can be provided at a lower position than the third water level sensor 111k3 and the eighth water level sensor 111k8.

[0087] Furthermore, the fifth water level sensor 111k5 and the tenth water level sensor 111k10 are provided at the same position on both sides of the upper interior of the housing 101, and can be positioned lower than the positions of the fourth water level sensor 111k4 and the ninth water level sensor 111k9.

[0088] The control phase, via the processor 122, applies ultrasonic waves corresponding to the irradiation limit angle when at least one of the housing 101 and the handpiece coupled to the housing 101 is positioned within an irradiation limit angle already set according to the fluid level and inclination level of the fluid L. Ultrasonic irradiator It can also control 130.

[0089] For example, as shown in Figure 12, the processor 122 senses the water level and inclination of the fluid L via the 4th, 5th, 8th, 9th, and 10th water level sensors (111k4, 111k5, 111k8, 111k9, and 111k10), and when at least one of the housing 101 and the handpiece is positioned within a 7th irradiation limit angle that has already been set according to the fluid level and inclination level, it applies ultrasonic waves corresponding to the 7th irradiation limit angle. Ultrasonic irradiator It can control 130. Here, Ultrasonic irradiator 130 can irradiate the skin with ultrasound corresponding to the seventh irradiation limit angle. In this case, the seventh irradiation limit angle may be a range in which irradiation is possible up to 240°, a range in which irradiation is possible up to 180°, a range in which irradiation is possible up to 150°, a range in which irradiation is possible up to 120°, or a range in which irradiation is possible up to 90°. Here, the processor 122 applies the ultrasound energy in steps to an already set intensity. Ultrasonic irradiator It is also possible to control 130. In this case, the already set intensity can be at least one of the following: weak intensity, medium intensity, or strong intensity.

[0090] As another example, as shown in Figure 13, the processor 122 senses the fluid level and inclination of the fluid L via the 5th to 10th water level sensors 111k5 to 111k10, and when at least one of the housing 101 and the handpiece is located within an 8th irradiation limit angle that is narrower than the 7th irradiation limit angle already set according to the fluid level and inclination level, it applies ultrasonic waves corresponding to the 8th irradiation limit angle. Ultrasonic irradiator It can control 130. Here, Ultrasonic irradiator 130 can irradiate the skin with ultrasound corresponding to the eighth irradiation limit angle. In this case, the eighth irradiation limit angle may be a range in which irradiation is possible up to 240°, a range in which irradiation is possible up to 180°, a range in which irradiation is possible up to 150°, a range in which irradiation is possible up to 120°, or a range in which irradiation is possible up to 90°. Here, the processor 122 applies the ultrasound energy in steps to an already set intensity. Ultrasonic irradiator It is also possible to control 130. In this case, the already set intensity can be at least one of the following: weak intensity, medium intensity, or strong intensity.
