Description

Technical Field

[0001] This application relates to the fields of medical devices and medical aesthetics, specifically to an ultrasonic treatment head and an ultrasonic beauty device containing the same. Background Technology

[0002] Current medical aesthetics utilizes ultrasonic energy to precisely heat the epidermis, dermis, superficial fat layer, and SMAS fascia layer. This concentrates heat energy at the treatment site, stimulating collagen regeneration and restructuring, resulting in rapid skin tightening. The heat from ultrasonic energy causes the receiving tissues to tighten, shrinking aged collagen and further stimulating collagen proliferation and restructuring, thus repairing the skin. Such products are widely accepted by the medical aesthetics community. The ultrasonic transducer, which emits ultrasonic energy, is the core component of these beauty products. Improving the efficiency and intelligence of ultrasonic transducers is a continuous pursuit in research and development.

[0003] Currently, in the treatment process of such medical aesthetic products, the operator holds a handheld device equipped with an ultrasonic transducer and moves it across the area to be treated to achieve skin repair. These traditional products can only emit pulses according to pre-set parameters, and the ultrasonic output energy is fixed. However, everyone's skin condition, and even the skin condition of different areas on the same person's face, is different. Users need highly specialized medical aesthetic skills to assess the patient's age and skin condition, and then manually adjust the device parameters to meet the needs of each individual patient.

[0004] Setting equipment parameters based on the operator's assessment of the patient's skin condition poses several significant risks: First, the qualifications of operators in the market vary greatly. A qualified operator will tailor a suitable treatment plan and energy level based on the patient's age, skin condition, and skin tolerance to ensure more effective treatment without damaging the skin. Second, the treatment time for the same area is crucial for energy distribution within the skin tissue. However, if the operator is inexperienced, too short a time will not achieve the desired therapeutic effect, while too long a time may lead to excessive energy accumulation, causing safety risks such as skin redness, stinging, facial nerve damage, facial stiffness, and other serious medical accidents.

[0005] Based on this, a therapeutic ultrasound transducer and an imaging ultrasound transducer can be integrated into the ultrasound treatment head. On the one hand, the treatment area is scanned and detected, and on the other hand, the treatment parameters of the therapeutic ultrasound transducer are automatically adjusted by analyzing the scan results. However, the ultrasonic energy of the therapeutic ultrasound transducer is very high, accompanied by high heat generation, which leads to a decrease in the output acoustic power and efficiency of the transducer. In addition, the ultrasonic energy reflected by the skin is still very high, which can damage the imaging ultrasound transducer, requiring the replacement of the imaging ultrasound transducer, thus greatly increasing the cost of equipment use.

[0006] Therefore, it is necessary to provide an improved ultrasound treatment head to solve the aforementioned problems existing in the prior art. Summary of the Invention

[0007] In view of this, the present application provides an ultrasonic treatment head and an ultrasonic beauty device containing the same, which can solve the problems of excessive reliance on operator experience, damage to the imaging ultrasonic transducer caused by high reflected energy, and poor heat dissipation of the transducer in the prior art. The technical solution is as follows: The first aspect of this application provides an ultrasonic treatment head, including a housing, within which a therapeutic ultrasonic transducer and an imaging ultrasonic transducer are disposed. It also includes a position drive assembly connected to the image ultrasonic transducer drive to change the position of the image ultrasonic transducer in the housing, thereby switching the image ultrasonic transducer between a working position and a safe position. When the imaging ultrasound transducer is in the working position, the therapeutic ultrasound transducer is in the off state, the imaging ultrasound transducer is in the on state, and the imaging ultrasound transducer is located at the center of the therapeutic ultrasound transducer to scan and detect the skin area. When the imaging ultrasound transducer is in a safe position, the imaging ultrasound transducer is in a closed state, and the therapeutic ultrasound transducer is in a closed state, so as to dynamically adjust the treatment parameters according to the scanning detection results, and the imaging ultrasound transducer is located outside the energy range of the ultrasound reflected by the therapeutic ultrasound transducer.

[0008] Preferably, the working position and the safe position are distributed along the axial direction of the housing.

[0009] Furthermore, the position drive assembly includes an internal bracket positioned axially along the housing, a transducer bracket for fixedly mounting the imaging ultrasound transducer, and an axial driver fixedly connected to the transducer bracket to drive the imaging ultrasound transducer to move along the axial direction between the working position and the safe position within the internal bracket.

[0010] Preferably, the axial actuator includes at least one of the following: a telescopic cylinder, a motor-screw-guide rod assembly, and a motor-telescopic rod.

[0011] Preferably, the outer wall of the transducer bracket side is designed with a groove, and a shock-absorbing rubber ring is installed in the groove.

[0012] Preferably, the working position and the safe position are distributed along a planar path within the housing.

[0013] Furthermore, the position drive assembly includes a transducer bracket for fixedly mounting the imaging ultrasound transducer and a planar actuator fixedly connected to the transducer bracket to drive the imaging ultrasound transducer to move along the planar path between the working position and the safe position.

[0014] Preferably, the planar actuator includes at least one of a telescopic cylinder, a motor, and an electric push rod.

[0015] Preferably, the planar path is an arc-shaped path, the planar driver is a motor, and the output shaft of the motor is fixedly connected to the end of the transducer bracket. Under the rotational drive of the motor output shaft, the transducer bracket drives the imaging ultrasound transducer to switch between the working position and the safe position along the arc-shaped path.

[0016] Furthermore, the ultrasound transducer also includes an acoustic lens, which is mounted on the surface of the imaging ultrasound transducer or disposed between the working position and the skin; the acoustic lens can transmit ultrasound waves at the working frequency of the imaging ultrasound transducer, but cannot transmit ultrasound waves at the working frequency of the therapeutic ultrasound transducer.

[0017] Furthermore, the ultrasonic transducer also includes a heat dissipation assembly.

[0018] Preferably, the heat dissipation assembly includes an inlet pipe and an outlet pipe sealed to the housing, and a liquid guiding cavity disposed within the housing. The height of the liquid guiding cavity along the axial direction is greater than or equal to the height of the therapeutic ultrasound transducer along the axial direction from the top to the bottom. At least one side of the liquid guiding cavity is provided with a chamber seal.

[0019] A second aspect of this application provides an ultrasonic beauty device, comprising: The ultrasonic treatment head described in any one of the first to eleventh embodiments above; The host is electrically connected to both the imaging ultrasound transducer and the therapeutic ultrasound transducer, thereby calculating and analyzing the data results of the imaging ultrasound transducer scanning and detecting in different regions and automatically adjusting the emission parameters of the therapeutic ultrasound transducer for the corresponding regions.

[0020] Preferably, the ultrasonic beauty device further includes a display system, which is electrically connected to the image ultrasonic transducer to output visualized detection results.

[0021] A third aspect of this application provides another ultrasonic beauty device, including: The ultrasonic treatment head described in the twelfth embodiment above; The host is electrically connected to both the imaging ultrasound transducer and the therapeutic ultrasound transducer, thereby calculating and analyzing the data results of the imaging ultrasound transducer scanning and detecting in different regions and automatically adjusting the emission parameters of the therapeutic ultrasound transducer for the corresponding regions.

[0022] A cooling circulation system includes a refrigerator and a circulation pump. The outlet of the refrigerator is fluidly connected to the inlet of the circulation pump, the outlet of the circulation pump is fluidly connected to the inlet pipe, and the outlet pipe is fluidly connected to the inlet of the refrigerator.

[0023] Preferably, the ultrasonic beauty device further includes a display system, which is electrically connected to the image ultrasonic transducer to output visualized detection results.

[0024] Compared with the prior art, the beneficial effects that at least one technical solution adopted in the embodiments of this specification can achieve include at least: First, this invention integrates both an imaging ultrasound transducer and a therapeutic ultrasound transducer in the ultrasound treatment head. The imaging ultrasound transducer feeds back the skin health status data detected by scanning in different areas to the host unit. After calculation and analysis, it can automatically adjust the emission parameters (such as emission power / emission frequency) of the therapeutic ultrasound transducer for different areas. Therefore, personalized ultrasound treatment plans can be obtained for different individuals and different locations, avoiding the treatment risks caused by over-reliance on the operator's experience, and allowing ordinary patients to perform cosmetic treatments at home.

[0025] Secondly, by selectively opening and closing the imaging ultrasound transducer and the therapeutic ultrasound transducer, the present invention avoids mutual interference between the two signals. At the same time, by setting a position drive assembly, the imaging ultrasound transducer can switch between the working position and the safe position in the axial or plane, which can effectively reduce the damage to the imaging ultrasound transducer caused by the reflected energy of the therapeutic ultrasound transducer and greatly reduce the cost of using the device.

[0026] Third, the present invention has a groove designed on the outer wall of the side of the transducer bracket, and a shock-absorbing rubber ring is installed in the groove. The shock-absorbing rubber ring is made of elastic material. When the therapeutic ultrasound transducer is working, the shock-absorbing rubber ring can effectively isolate the vibration generated by the therapeutic ultrasound transducer, thereby protecting the imaging ultrasound transducer.

[0027] Fourth, another important aspect of this invention is that by providing an acoustic lens on the surface of the imaging ultrasound transducer or between the working position and the skin, the acoustic lens can transmit ultrasound waves at the working frequency of the imaging ultrasound transducer, but blocks ultrasound waves at the working frequency of the therapeutic ultrasound transducer, thereby further preventing damage to the imaging ultrasound transducer from the energy of the therapeutic ultrasound transducer.

[0028] Fifth, by setting up a heat dissipation assembly and a cooling circulation system, the present invention ensures that the height of the liquid guiding cavity is greater than or equal to the height of the therapeutic ultrasound transducer along the axial direction from the top to the bottom. This allows the therapeutic ultrasound transducer to be completely immersed in the liquid guiding cavity. Under the action of the circulation pump and the refrigerator, the heat-conducting fluid used for heat conduction is continuously circulated, pumping the cooled heat-conducting fluid into the liquid guiding cavity to complete the heat exchange with the therapeutic ultrasound transducer, which greatly improves the heat dissipation efficiency of the therapeutic ultrasound transducer.

[0032] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0033] The following specific examples illustrate the implementation of this application. Those skilled in the art can easily understand other advantages and effects of this application from the content disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. This application can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this application. It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0034] It should be noted that the terms "first," "second," etc., used in the specification, claims, and drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. The terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. Furthermore, the term "proximal" refers to the end of the ultrasound treatment head closer to the operator, while "distal" refers to the end of the ultrasound treatment head closer to the user.

[0035] Figure 1The diagram shown is a structural schematic of the first embodiment of the ultrasonic treatment head of the present invention. The ultrasonic treatment head 1 includes a shell 11, and a therapeutic ultrasonic transducer 12 and an imaging ultrasonic transducer 13 are provided inside the shell 11. When the imaging ultrasonic transducer 13 is in the working position, it is concentrically arranged with the therapeutic ultrasonic transducer 12, and the imaging ultrasonic transducer 13 is basically located at the center 121 of the therapeutic ultrasonic transducer 12. In the existing technology, the ultrasonic energy of the therapeutic ultrasound transducer 12 is very high, with an intensity range of 0.1 W / cm² to 3.0 W / cm² in continuous wave mode, while the ultrasonic energy of the imaging ultrasound transducer 13 is very low, with an intensity range of only 0.001 W / cm² to 0.5 W / cm². The typical working intensity of therapeutic ultrasound is tens to thousands of times or even higher than that of diagnostic ultrasound. Diagnostic ultrasound transducers are precision instruments designed to receive extremely weak echoes. Their core is a piezoelectric ceramic wafer (such as PZT). When faced with the high-intensity energy reflected back by therapeutic ultrasound, they are easily damaged due to piezoelectric material overload and depolarization, thermal damage, mechanical damage caused by cavitation effect and acoustic radiation force, and circuit overload. The imaging ultrasound transducer must be replaced, which greatly increases the cost of equipment use.

[0036] To overcome the aforementioned technical deficiencies, this embodiment further includes a position drive assembly 14. This position drive assembly 14 can be driven and connected to the image ultrasound transducer 13 to change the position of the image ultrasound transducer 13 within the housing 11, thereby switching the image ultrasound transducer 13 between a working position and a safe position. Specifically, in this embodiment, the position drive assembly 14 includes an internal support 141 axially positioned within the housing 11 and a transducer support 142 for fixedly mounting the image ultrasound transducer 13. The transducer support 142 can drive the image ultrasound transducer 13 to slide along the axial guide axis formed by the internal support 141. The internal support 141 defines the working position 141a and the safe position 141b of the image ultrasound transducer 13. Figure 2a As shown, when the imaging ultrasound transducer 13 is in the working position 141a, the therapeutic ultrasound transducer 12 is in the off state, and the imaging ultrasound transducer 13 is in the on state. The transducer support 142 is basically located at the distal end 1411 of the internal support 141, which satisfies the transmission and reception distance of the imaging ultrasound, thereby enabling a comprehensive scan of the skin area. Figure 2bAs shown, when the imaging ultrasound transducer 13 is in the safe position 141b, the therapeutic ultrasound transducer 12 is in the open state, and the imaging ultrasound transducer 13 is in the closed state. The transducer support 142 slides to the proximal end 1412 of the inner support 141. Since the imaging ultrasound transducer 13, which has reached the safe position 141b, is far away from the therapeutic ultrasound transducer 12, the damage of the reflected energy 12a of the therapeutic ultrasound transducer 12 to the imaging ultrasound transducer 13 can be effectively reduced, which greatly reduces the cost of using the device.

[0037] Alternatively, to prevent the transducer bracket 142 from detaching from the inner bracket 141 during movement, necessary limiting mechanisms (not released) may be provided on the inner bracket 141 at the working position 141a and / or the safety position 141b.

[0038] In some preferred embodiments, the outer wall of the transducer bracket 142 may also be designed with a groove 1421, in which a shock-absorbing rubber ring 1422 is installed. The rubber ring is made of an elastic material, including but not limited to natural rubber, nitrile rubber, neoprene rubber, EPDM rubber, silicone rubber, fluororubber, polyurethane rubber, and thermoplastic elastomer. When the therapeutic ultrasound transducer 12 is working, the shock-absorbing rubber ring 1422 can effectively isolate the vibration generated by the therapeutic ultrasound transducer 12, thereby protecting the imaging ultrasound transducer 13.

[0039] To precisely move the transducer bracket 142 to the working position 141a and the safe position 141b, the position drive assembly 14 further includes an axial drive 143 fixedly connected to the transducer bracket 142 to drive the transducer bracket 142 to move between the working position 141a and the safe position 141b within the inner bracket 141. The axial drive 143 includes, but is not limited to, a telescopic cylinder, a motor-screw-guide rod assembly, and a motor-telescopic rod; however, those skilled in the art should understand that any axial drive 143 capable of driving the transducer bracket 142 to move axially should be included within the scope of protection of this invention. Figure 3The diagram shown is a perspective view of a preferred axial actuator of the present invention. The axial actuator 143 includes a drive motor 1431, a motor bracket 1432, a drive screw 1433, a guide rod 1434, a push rod connector 1435, and a transducer connecting rod 1436. The drive motor 1431 is fixedly connected to the motor bracket 1432, which is preferably a U-shaped bracket. The drive screw 1433 and the guide rod 1434 are both mounted between the two arms of the U-shaped bracket. One end of the drive screw 1433 is fixedly connected to the output shaft of the drive motor 1431. The push rod connector 1435 rotates along the axial direction under the rotation drive of the output shaft. The push rod connector 1435 is screwed to the drive screw 1433 through the threaded hole 1435a, sleeved with the guide rod 1434 through the guide hole 1435b, and fixedly connected to one end of the transducer connecting rod 1436 through the locking hole 1435c. In order to improve the stability of the transducer connecting rod 1436 during movement, a snap ring 1437 can be added at the locking hole 1436 to lock the transducer connecting rod 1436. The other end of the transducer connecting rod 1436 is fixedly connected to the transducer bracket 142. During use, when the imaging ultrasound transducer 13 needs to move upward to the safe position 141b, the drive motor 1431 rotates forward, driving the drive screw 1433 to rotate forward. The push rod connector 1435 moves upward due to the guidance of the guide rod 1434, and then drives the bottom imaging ultrasound transducer 13 to move upward through the transducer connecting rod 1436. Conversely, if the imaging ultrasound transducer 13 needs to move downward to the working position 141a, the drive motor 1431 simply reverses direction. This embodiment uses a motor-screw-guide rod assembly type axial driver 143, which can convert the rotational motion of the drive motor 1431 into the linear motion of the drive screw 1433 within the limited space inside the housing 11, realizing the axial up-and-down movement of the imaging ultrasound transducer 13, thereby preventing damage to the imaging ultrasound transducer 13 while satisfying a smaller radial area. It should be understood that this driving method is only a preferred embodiment. All position driving assemblies that can achieve axial driving are included in the inventive concept of this invention. The specific structure of this preferred embodiment should not be construed as limiting the scope of protection of the independent claims.

[0040] To further reduce the damage rate of the aforementioned imaging ultrasound transducer, such as Figure 4As shown, in this embodiment, a novel composite material acoustic lens 131 can be preferably fixedly installed on the surface of the imaging ultrasound transducer 13 or at the distal end 1411 of the working position of the internal support 141. The acoustic lens 131 can transmit ultrasound waves of a specific frequency emitted by the imaging ultrasound transducer and reflected back through the skin, but cannot transmit ultrasound waves of the working frequency of the therapeutic ultrasound transducer 12. This can prevent the energy of the therapeutic ultrasound transducer 12 from damaging the imaging ultrasound transducer 13. The material of the acoustic lens 131 includes, but is not limited to, silicone rubber-based composite materials, specially formulated polyurethane composite materials, and phonon crystals / metamaterials.

[0041] The operation of therapeutic ultrasound transducers is accompanied by high heat generation, which leads to a decrease in the transducer's output acoustic power and efficiency. To overcome these technical shortcomings, such as... Figure 5 As shown, the ultrasonic treatment head of this embodiment can further be provided with a heat dissipation assembly 15 inside the housing. The heat dissipation assembly 15 includes an inlet pipe 151 and an outlet pipe 152 sealed and connected to the outer housing 11, and a liquid guiding cavity 153 disposed inside the housing and in fluid communication with both the inlet pipe 151 and the outlet pipe 152. The height of the liquid guiding cavity 153 along the axial direction is greater than or equal to the height of the therapeutic ultrasonic transducer 12 along the axial direction from the top to the bottom, thereby immersing the entire therapeutic ultrasonic transducer 12 in the coolant in the liquid guiding cavity 153, thus protecting the therapeutic ultrasonic transducer. 12. To achieve the most adequate cooling and ensure that the output power meets the treatment requirements; in order to prevent the coolant from flowing out of the liquid guiding cavity 153 and damaging the circuit board and other electrical components inside the housing, at least one side of the liquid guiding cavity 153 is preferably provided with a chamber seal 1531. In this embodiment, the chamber seal 1531 is provided at the top of the liquid guiding cavity 153, but this arrangement is only a preferred example. The chamber seal 1531 can be provided on any one or more sides of the liquid guiding cavity 153 as needed by those skilled in the art, provided that the sealing requirements are met.

[0042] Figures 6a-6cThe diagram shown is a structural schematic of a second embodiment of the ultrasonic treatment head of the present invention. Unlike the first embodiment, where the working position and the safe position are distributed along the axial direction of the internal support, in this embodiment, the working position and the safe position are distributed along a radial plane within the outer shell. Correspondingly, the position drive assembly 14 includes a transducer bracket 142 for fixedly mounting the imaging ultrasonic transducer 13, and a planar actuator 144 fixedly connected to the transducer bracket 142 to drive the imaging ultrasonic transducer 13 to move along the radial plane between the working position and the safe position. The planar actuator 144 includes, but is not limited to, a telescopic cylinder, a motor, and an electric push rod; however, those skilled in the art should understand that any planar actuator 144 capable of driving the transducer bracket 142 to move along the radial plane should be included within the protection scope of the present invention. In this embodiment, the planar driver 144 includes a drive motor 1431 and a motor bracket. The drive motor 1431 is fixedly connected to the motor bracket, and the output shaft of the drive motor 1431 is fixedly connected to a rotating shaft. The rotating shaft is fixedly connected to a transducer bracket 142. Under the drive of the drive motor 1431, the transducer bracket 142 performs radial planar circular motion within the housing 11 about the rotating shaft as its center. Figure 6b As shown, when the imaging ultrasound transducer 13 is in the working position 141a, the therapeutic ultrasound transducer 12 is in the off state. The drive motor 1431 rotates the transducer support 142 to the center region of the therapeutic ultrasound transducer 12 and keeps the imaging ultrasound transducer 13 in the on state, scanning the skin area. Figure 6c As shown, after scanning is completed, the imaging ultrasound transducer 13 switches to the off state. The drive motor 1431 rotates the transducer bracket 142 clockwise or counterclockwise to move it away from the central area of ​​the therapeutic ultrasound transducer 12 and reach a safe position 141b. At this time, the therapeutic ultrasound transducer 12 switches to the on state. At this safe position 141b, the imaging ultrasound transducer 13 cannot receive the high-energy ultrasound waves emitted and reflected by the therapeutic ultrasound transducer 12, thereby protecting the imaging ultrasound transducer 13. This embodiment uses a radial planar circular motion position drive assembly that can directly realize the displacement of the imaging ultrasound transducer 13 in the plane using the rotational motion of the drive itself, without the need for additional structural conversion. The structure is simple and highly reliable. However, it should be understood that this drive method is only a preferred embodiment. Any position drive assembly that can realize radial planar driving action, such as linear reciprocating drive, is included in the inventive concept of this invention. The specific structure of this preferred embodiment should not be construed as limiting the scope of protection of the independent claims.

[0043] In a second aspect, the present invention also provides an ultrasonic beauty device, such as... Figure 7As shown, the ultrasonic beauty device 2 includes: the ultrasonic treatment head 1 described in any embodiment of the first aspect above; The host unit 21 is electrically connected to both the imaging ultrasound transducer 13 and the therapeutic ultrasound transducer 12. This allows the host unit to calculate and analyze the data from the imaging ultrasound transducer 13 scanning different regions and automatically adjust the emission parameters of the therapeutic ultrasound transducer 12 for those different regions. Preferably, the ultrasound beauty device also includes a display system 22, which is electrically connected to the imaging ultrasound transducer via the host unit 21 to output visualized detection results.

[0044] Preferably, the ultrasonic beauty device 2 of the present invention may further be equipped with a cooling circulation system 23. The cooling circulation system 23 includes a refrigerator 231 and a circulation pump 232. The outlet of the refrigerator 231 is fluidly connected to the inlet of the circulation pump 232, the outlet of the circulation pump 232 is fluidly connected to the inlet pipe 151, and the outlet pipe 152 is fluidly connected to the inlet of the refrigerator 231. The cooling circulation system 23 of this embodiment can fully dissipate heat from the therapeutic ultrasonic transducer 12. Within the fluid-conducting cavity 153, a heat-conducting fluid is filled between the therapeutic ultrasound transducer 12 and the chamber seal 1531. Driven by the circulation pump 232, this heat-conducting fluid enters the fluid-conducting cavity 153 from the inlet pipe 151 and absorbs the heat generated by the operation of the therapeutic ultrasound transducer 12. After absorbing heat, the heat-conducting fluid flows out from the outlet pipe 152 and is cooled at the refrigerator 231 before re-entering the system through the inlet pipe 151 for recycling. This completes the sufficient cooling of the therapeutic ultrasound transducer 12, ensuring its ultrasound emission efficiency.

[0045] The ultrasonic beauty device of this invention is used in two steps: Step 1, the operator holds the ultrasonic treatment head of this invention and scans the skin area of ​​the patient to be treated. At this time, the imaging ultrasonic transducer 13 is in the working position 141a. During the scanning process, the treatment ultrasonic transducer 12 is in the off state, while the imaging ultrasonic transducer 13 is in the on state. The imaging ultrasonic transducer 13 can accurately detect the scanned skin area and output the visual detection results to the display system 22. Step 2, after the scanning is completed, the device host 21 automatically sets the transmission power, number of excitations, and other key parameters of the treatment ultrasonic transducer 12 based on the detection results. The operator performs precise treatment on the patient based on these parameters. At this time, the imaging ultrasonic transducer 13 is in the safe position 141b. Based on the accurate detection results of the imaging ultrasonic transducer 13, each patient can receive a personalized treatment plan corresponding to their own skin treatment, thereby avoiding poor treatment results or serious medical accidents such as skin redness, stinging, facial nerve damage, and facial stiffness caused by insufficient operator experience or misjudgment. After treatment, the operator can use the detection function of the imaging ultrasound transducer 13 to perform another detection to ensure that the treatment effect meets expectations.
