Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a treatment head and treatment device. Background Technology

[0002] In most existing high-frequency therapy products, the treatment head automatically determines whether to start by detecting whether it is in contact with the skin treatment surface. The contact detection between the treatment head and the skin treatment surface is basically achieved by capacitive contact sensors or light-sensing sensors.

[0003] However, both methods have certain limitations. For example, when high-frequency treatment devices that simultaneously output ultrasound and radiofrequency energy are used for treatment, an ultrasound coupling agent (gel) needs to be coated on the treatment surface to conduct the ultrasound energy to the subcutaneous tissue, since the conduction of ultrasound energy requires a sound-conducting medium. However, treatment devices using capacitive contact sensors are prone to false sensing. The capacitive contact sensor is easily triggered when it comes into contact with the medical gel, causing the treatment head to start operating even when it is not in contact with the treatment surface. In dark or low-light environments, the light-sensing detection sensor may fail or have insufficient detection accuracy, and the treatment head cannot determine whether to start by detecting whether it is in contact with the treatment surface. Summary of the Invention

[0004] The main objective of this invention is to provide a treatment head and treatment device that improves the applicability and accuracy of skin contact detection.

[0005] To achieve the above objectives, the present invention provides a treatment head comprising:

[0006] Housing assembly;

[0007] An electrode structure is mounted on the end face of the housing assembly;

[0008] A deformation sensing element is mounted on the housing assembly, and the deformation sensing element is located on the side of the electrode structure closer to the housing assembly;

[0009] The electrode structure and the deformation sensing sheet are electrically connected to the control board. When the electrode structure presses the deformation sensing sheet and causes the deformation sensing sheet to deform, the control board detects the deformation of the deformation sensing sheet and controls the electrode structure to emit electrical energy according to the deformation of the deformation sensing sheet.

[0010] In one embodiment, the treatment head further includes an elastic element, at least a portion of which passes through the housing assembly. The elastic element is located between the electrode structure and the deformation sensing sheet, and is connected to both the electrode structure and the deformation sensing sheet.

[0011] In one embodiment, the housing assembly includes a first housing and a second housing, the elastic element is located between the first housing and the second housing, and the elastic element is at least partially penetrated through the first housing, the electrode structure is mounted on the side of the first housing away from the elastic element, and the deformation sensing sheet is mounted on the side of the second housing close to the elastic element.

[0012] In one embodiment, the elastic element includes a first protrusion structure that passes through the first housing and is in contact with the surface of the electrode structure.

[0013] In one embodiment, the elastic member further includes a second protrusion structure located on the side of the elastic member away from the first housing, and the second protrusion structure is in contact with the surface of the deformation sensing sheet.

[0014] In one embodiment, a clearance groove is provided on the end face of the first housing away from the second housing, and the elastic element is at least partially located in the clearance groove. The clearance groove is used to provide deformation space for the electrode structure, and the clearance groove gradually shrinks from the first housing to the second housing.

[0015] In one embodiment, the first housing is provided with a positioning protrusion structure, and the elastic member is provided with a positioning hole. The positioning protrusion structure is adapted to partially pass through the positioning hole to achieve positioning between the elastic member and the first housing.

[0016] In one embodiment, the first housing has a first opening, the second housing has a second opening, the second housing is at least partially inserted through the first opening, and the second opening is covered with a sound-permeable membrane to seal the second opening.

[0017] In one embodiment, the treatment head further includes an ultrasonic transducer mounted within the second housing and adapted to emit ultrasonic energy through the second opening.

[0018] The present invention also proposes a therapeutic device, which includes a therapeutic head as described above.

[0019] The technical solution of this invention includes a treatment head comprising a housing assembly, an electrode structure, and a deformation sensing plate. The electrode structure is mounted on the end face of the housing assembly; the deformation sensing plate is mounted on the housing assembly and located on the side of the electrode structure closer to the housing assembly. The electrode structure and the deformation sensing plate are electrically connected to a control board. When the electrode structure presses against the deformation sensing plate, causing deformation, the control board detects the deformation and controls the electrode structure to emit electrical energy based on this deformation. When the treatment head performs treatment, the electrode structure contacts the treatment surface of the skin and undergoes slight deformation due to compression. The electrode structure transmits this deformation to the deformation sensing plate. At this time, the control board, electrically connected to the deformation sensing plate, detects the deformation and controls the electrode structure to emit electrical energy, initiating treatment. Regardless of whether the treatment head performs stamping or sliding treatment, the control board can accurately determine whether the electrode structure is in contact with the treatment surface and control the working state of the electrode structure accordingly. The triggering method of this electrode structure is unaffected by ambient brightness or whether medical gel or other coatings are applied to the treatment surface, greatly improving the applicability and accuracy of contact detection between the treatment head and the treatment surface.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0036] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0037] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or" or "and / or" throughout the text includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0038] In related technologies, most existing high-frequency treatment products automatically determine whether to start by detecting whether the treatment head is in contact with the skin treatment surface. The contact detection of the treatment head with the skin treatment surface is basically achieved by capacitive contact sensors or light-sensing sensors.

[0039] However, both methods have certain limitations. For example, when high-frequency treatment devices that simultaneously output ultrasound and radiofrequency energy are used for treatment, an ultrasound coupling agent (gel) needs to be coated on the treatment surface to conduct the ultrasound energy to the subcutaneous tissue, since the conduction of ultrasound energy requires a sound-conducting medium. However, treatment devices using capacitive contact sensors are prone to false sensing. The capacitive contact sensor is easily triggered when it comes into contact with the medical gel, causing the treatment head to start operating even when it is not in contact with the treatment surface. In dark or low-light environments, the light-sensing detection sensor may fail or have insufficient detection accuracy, and the treatment head cannot determine whether to start by detecting whether it is in contact with the treatment surface.

[0040] Please refer to the reference. Figures 1 to 11 As shown, the present invention proposes a treatment head 100, which includes a housing assembly 1, an electrode structure 2, and a deformation sensing plate 3. The electrode structure 2 is mounted on the end face of the housing assembly 1; the deformation sensing plate 3 is mounted on the housing assembly 1 and is located on the side of the electrode structure 2 closer to the housing assembly 1; wherein, the electrode structure 2 and the deformation sensing plate 3 are electrically connected to a control board 4 respectively. When the electrode structure 2 presses the deformation sensing plate 3 and causes the deformation sensing plate 3 to deform, the control board 4 detects the deformation of the deformation sensing plate 3 and controls the electrode structure 2 to emit electrical energy according to the deformation of the deformation sensing plate 3.

[0041] In this embodiment, the electrode structure 2 is mounted on the end face of the housing assembly 1. When the treatment head 100 performs treatment, the electrode structure 2 contacts the treatment surface of the skin and undergoes slight deformation due to compression. The electrode structure 2 transmits this deformation to the deformation sensing plate 3. At this time, the control board 4, which is electrically connected to the deformation sensing plate 3, detects the deformation of the deformation sensing plate 3 and controls the electrode structure 2 to emit electrical energy, thus initiating treatment. Regardless of whether the treatment head 100 performs stamping or sliding treatment, the control board 4 can accurately determine whether the electrode structure 2 is in contact with the treatment surface and control the working state of the electrode structure 2 accordingly. This triggering method of the electrode structure 2 is not affected by the ambient brightness or whether the treatment surface is coated with medical gel or other coatings, greatly improving the applicability and accuracy of the contact detection between the treatment head 100 and the treatment surface. The electrode structure 2 and the deformation sensing plate 3 are separately configured, allowing for targeted replacement when one of them is damaged, thereby reducing replacement costs.

[0042] Understandably, the control board 4 is equipped with a control unit and a deformation detection unit or pressure detection unit. The control unit is used to control the working state of the electrode structure 2, and the deformation detection unit or pressure detection unit is used to detect the deformation or pressure of the deformation sensing element 3. When the deformation sensing element 3 deforms, the deformation detection unit or pressure detection unit detects the deformation or pressure of the deformation sensing element 3 and sends a relevant signal to the control unit. After receiving the signal, the control unit controls the electrode structure 2 to start working and emit electrical energy. The electrode structure 2 and the deformation sensing element 3 can be FPC structures, both of which have a certain elastic deformation capability.

[0043] Optionally, the deformation sensing element 3 and the electrode structure 2 can be located on the same side of the housing assembly 1 or on different sides of the housing assembly 1. When the deformation sensing element 3 and the electrode structure 2 are located on the same side of the housing assembly 1, they can be in direct contact to transmit deformation. When the deformation sensing element 3 and the electrode structure 2 are located on different sides of the housing assembly 1, they can transmit deformation through an intermediate connector.

[0044] In one embodiment of the present invention, such as Figures 2 to 4 As shown, the treatment head 100 also includes an elastic element 5, at least a portion of which is disposed through the housing assembly 1. The elastic element 5 is located between the electrode structure 2 and the deformation sensing sheet 3, and is connected to the electrode structure 2 and the deformation sensing sheet 3 respectively.

[0045] In this embodiment, the electrode structure 2 and the deformation sensing plate 3 transmit deformation through the elastic element 5. When the electrode structure 2 is compressed and deformed, it presses against the elastic element 5, which transmits the force to the deformation sensing plate 3, causing the plate to deform accordingly. This allows the electrode structure 2 and the deformation sensing plate 3 to be installed at different locations on the housing assembly 1, improving their installation adaptability and reducing the design and layout complexity of the internal structure of the treatment head 100.

[0046] Understandably, the elastic element 5 has a certain deformation capacity. The electrode structure 2 and the deformation sensing plate 3 are connected by the elastic element 5, which can prevent the electrode structure 2 and the deformation sensing plate 3 from being damaged during deformation due to the excessively hard material of the connecting part in the middle, thus preventing them from failing to work properly. Optionally, the elastic element 5 can be made of rubber, plastic, or spring-shaped metal, and no specific limitation is made here.

[0047] In one embodiment of the present invention, such as Figures 2 to 7 As shown, the housing assembly 1 includes a first housing 11 and a second housing 12. An elastic member 5 is located between the first housing 11 and the second housing 12, and the elastic member 5 is at least partially inserted through the first housing 11. An electrode structure 2 is installed on the side of the first housing 11 away from the elastic member 5, and a deformation sensing sheet 3 is installed on the side of the second housing 12 close to the elastic member 5.

[0048] In this embodiment, the first housing 11 and the second housing 12 serve as the mounting structure and support structure for the electrode structure 2 and the deformation sensing element 3, respectively. During assembly, the electrode structure 2 and the deformation sensing element 3 are located on opposite sides of the first housing 11. At least a portion of the elastic element 5 passes through the first housing 11 to connect with the electrode structure 2 and the deformation sensing element 3, respectively, transmitting the deformation of the electrode structure 2 to the deformation sensing element 3. The deformation sensing element 3 is positioned between the first housing 11 and the second housing 12. The first housing 11 protects the deformation sensing element 3 from external environmental corrosion, preventing it from shortening its service life. It also reduces the possibility of deformation of the deformation sensing element 3 caused by factors other than the deformation of the electrode structure 2, thereby improving the accuracy and reliability of the deformation sensing element 3 in sensing the deformation of the electrode structure 2.

[0049] In actual implementation, the electrode structure 2 is installed on the end face of the first housing 11 away from the second housing 12. The first housing 11 is sleeved on the outside of the second housing 12. The deformation sensing sheet 3 is installed on the end face of the second housing 12 close to the first housing 11. The first housing 11 can enclose and form a mounting cavity 119. The control board 4 and related electronic components can be installed in the mounting cavity 119.

[0050] In one embodiment, such as Figure 6 , Figure 8 , Figure 9 and Figure 10 As shown, the electrode structure 2 has a first connecting arm 21, and the first housing 11 has a notch 115 corresponding to the first connecting arm 21. The first connecting arm 21 passes through the notch 115 to connect with the control board 4 located inside the housing assembly 1, thereby realizing the electrical connection between the electrode structure 2 and the control board 4. The deformation sensing sheet 3 has a second connecting arm 31, which is used to connect with the control board 4 to realize the electrical connection between the deformation sensing sheet 3 and the control board 4.

[0051] Optionally, the elastic element 5 can be arranged in a ring or column shape. The first housing 11 has a through hole 112 corresponding to the elastic element 5, and at least a portion of the elastic element 5 passes through the through hole 112, which is not specifically limited here. The second housing 12 has a receiving groove 121 corresponding to the deformation sensing sheet 3. The deformation sensing sheet 3 is installed in the receiving groove 121, and the size of the receiving groove 121 matches the size of the deformation sensing sheet 3 to facilitate the positioning and installation of the deformation sensing sheet 3. The first housing 11 and the second housing 12 can be arranged separately or as a single unit. In this embodiment, the first housing 11 and the second housing 12 are arranged separately to facilitate the installation of the deformation sensing sheet 3.

[0052] In one embodiment of the present invention, such as Figure 3 , Figure 4 , Figure 10 and Figure 11 As shown, the elastic member 5 includes a first protrusion structure 51, which passes through the first housing 11 and is in contact with the surface of the electrode structure 2.

[0053] In this embodiment, the first protrusion 51 in the elastic element 5 is in contact with the electrode structure 2, so the elastic element 5 can specifically receive the deformation of the electrode structure 2 and more effectively transmit the deformation of the electrode structure 2 along the axial direction. When the electrode structure 2 abuts against the treatment surface, the electrode structure 2 is more prone to deformation, thereby making the deformation sensing sheet 3 more accurately detect the deformation and improving the accuracy of triggering the treatment head 100. It can be understood that the contact surface between the first protrusion 51 and the electrode structure 2 is planar to better fit the surface of the electrode structure 2, which is beneficial for accurately transmitting the deformation of the electrode structure 2.

[0054] In one embodiment of the present invention, such as Figure 3 , Figure 4 , Figure 10 and Figure 11 As shown, the elastic member 5 also includes a second protrusion structure 52, which is located on the side of the elastic member 5 away from the first housing 11, and the second protrusion structure 52 is in contact with the surface of the deformation sensing sheet 3.

[0055] In this embodiment, the second protrusion structure 52 in the elastic member 5 is attached to the deformation sensing sheet 3. When the electrode structure 2 compresses the elastic member 5, the elastic member 5 transmits force and deformation to the deformation sensing sheet 3 in the axial direction through the second protrusion structure 52, so that the deformation sensing sheet 3 can receive the deformation of the electrode structure 2 in a timely manner. It can be understood that the contact surface between the second protrusion structure 52 and the electrode structure 2 can be planar to better fit the surface of the deformation sensing sheet 3, which is beneficial to accurately transmit force and deformation to the deformation sensing sheet 3.

[0056] Optionally, the first protrusion structure 51 and the second protrusion structure 52 can be coaxially arranged to shorten the transmission path of the deformation of the elastic element 5, so that the elastic element 5 can quickly transmit deformation along the axial direction and improve the immediacy of the triggering of the treatment head 100. Optionally, the elastic element 5 can be arranged in a columnar shape, with the first protrusion structure 51 and the second protrusion structure 52 located at both ends of the elastic element 5, respectively.

[0057] In actual implementation, such as Figures 2 to 4 , Figure 10 and Figure 11 As shown, the elastic element 5 also includes a connecting ring 53. The first protruding structure 51 and the second protruding structure 52 are respectively connected to the front and back sides of the connecting ring 53. The elastic element 5 is connected to the first housing 11 through the connecting ring 53. Optionally, the elastic element 5 may only include the first protruding structure 51 and the connecting ring 53. The first protruding structure 51 is connected to one side of the connecting ring 53, and the connecting ring 53 abuts against the deformation sensing sheet 3, directly transmitting deformation to the deformation sensing sheet 3. No specific limitation is made here.

[0058] Understandably, when the first protruding structure 51 and the second protruding structure 52 are located on the front and back sides of the connecting ring 53, the connecting ring 53 is connected to the first housing 11 only through the surface excluding the surfaces covered by the first protruding structure 51 and the second protruding structure 52. The first protruding structure 51 and the second protruding structure 52 have no direct connection to the first housing 11, thus forming a cantilever structure with the connecting ring 53. When the electrode structure 2 does not deform, the elastic element 5 and the first housing 11 are relatively fixed in position. The first protruding structure 51 and the second protruding structure 52 only adhere to the electrode structure 2 and the deformation sensing plate 3 respectively without transmitting force or deformation. When the electrode structure 2 deforms, the first protruding structure 51 and the second protruding structure 52, along with the corresponding portion of the connecting ring 53, can flexibly deform to transmit the deformation of the electrode structure 2 to the deformation sensing plate 3. This cantilever structure deformation transmission method effectively improves the accuracy and immediacy of the deformation transmission by the elastic element 5. The elastic element 5 is connected to the first housing 11 via the connecting ring 53, which increases the connection area between the elastic element 5 and the first housing 11, improves the installation stability of the elastic element 5, and reduces the possibility of the treatment head 100 being falsely triggered due to deformation of the elastic element 5 under unexpected circumstances.

[0059] Optionally, the first protrusion structure 51, the connecting ring 53, and the second protrusion structure 52 can be integrally formed. The connecting ring 53 can be connected to the side of the first housing 11 near the electrode structure 2, or it can be connected to the side of the first housing 11 away from the electrode structure 2. For example, the connecting ring 53 can be connected to the side of the first housing 11 away from the electrode structure 2 by adhesive bonding or heat fusion.

[0060] Optionally, multiple first protrusion structures 51 can be provided. Correspondingly, multiple through holes 112 are also provided on the first housing 11 for the first protrusion structures 51 to pass through. Each first protrusion structure 51 passes through a through hole 112, and the second protrusion structure 52 is also provided in a one-to-one correspondence with the first protrusion structure 51.

[0061] In actual implementation, the end face of the second protrusion structure 52 can be tapered from the electrode structure 2 toward the deformation sensing sheet 3 to reduce the contact area between the second protrusion structure 52 and the deformation sensing sheet 3, increase the pressure on the deformation sensing sheet 3 when the elastic member 5 transmits deformation to the deformation sensing sheet 3, and at the same time, the deformation of the deformation sensing sheet 3 is more concentrated, thereby improving the sensitivity of the deformation sensing sheet 3 in receiving deformation.

[0062] In one embodiment of the present invention, such as Figure 5 , Figure 6 , Figure 10 and Figure 11 As shown, the end face of the first housing 11 away from the second housing 12 is provided with a relief groove 111. The elastic member 5 is at least partially located in the relief groove 111. The relief groove 111 is used to provide deformation space for the electrode structure 2. The relief groove 111 gradually shrinks from the first housing 11 to the second housing 12.

[0063] In this embodiment, the first housing 11 provides deformation space for the electrode structure 2 by providing a relief groove 111. When the electrode structure 2 is installed on the end face of the first housing 11, the electrode structure 2 covers the opening of the relief groove 111, and the covered part of the electrode structure 2 is in a suspended state and abuts against at least a portion of the elastic element 5 located in the relief groove 111. When the electrode structure 2 contacts the treatment surface of the skin and undergoes compression deformation, the electrode structure 2 deforms into the relief groove 111 to compress at least a portion of the elastic element 5 located in the relief groove 111, thereby transmitting the deformation to the deformation sensing plate 3. The relief groove 111 gradually contracts from the first housing 11 towards the second housing 12 to expand the area of ​​the suspended part of the electrode structure 2, ensuring that the electrode structure 2 can deform when in contact with the treatment surface, and simultaneously concentrating the deformation of the electrode structure 2 caused by compression towards the position of the elastic element 5. The elastic element 5 can receive the deformation of the electrode structure 2 in a timely manner and transmit the deformation to the deformation sensing plate 3.

[0064] In actual implementation, the through hole 112 on the first housing 11 through which the elastic element 5 passes is connected to the relief groove 111. The first protrusion 51 of the elastic element 5 passes through the through hole 112 and extends into the relief groove 111 to abut against the electrode structure 2. The through hole 112 is located in the middle of the relief groove 111, and the groove wall of the relief groove 111 is inclined from the groove opening to the through hole 112, thereby realizing the contraction setting of the relief groove 111. Optionally, the second housing 12 can be provided with a relief groove 122 corresponding to the deformation sensing plate 3. When the deformation sensing plate 3 is installed on the second housing 12, the deformation sensing plate 3 covers the groove opening of the relief groove 122, and the relief groove 122 provides deformation space for the deformation sensing plate 3.

[0065] Optionally, the end face of the first housing 11 may be provided with a placement groove 113 for mounting the electrode structure 2. The size of the placement groove 113 matches the size of the electrode structure 2 to facilitate the positioning and installation of the electrode structure 2. The electrode structure 2 can be adhered to the end face of the first housing 11 by adhesive. The end face of the first housing 11 may be provided with a groove 117. When the adhesive is adhered to the end face of the first housing 11, part of the adhesive will fill the groove 117, thereby increasing the adhesive area and allowing the adhesive to fully engage and adhere to the end face of the first housing 11, improving the adhesion between the adhesive and the end face of the first housing 11, and ensuring the firmness of the installation of the electrode structure 2.

[0066] In one embodiment of the present invention, such as Figures 3 to 6 As shown, the first housing 11 is provided with a positioning protrusion structure 114, and the elastic member 5 is provided with a positioning hole 531. The positioning protrusion structure 114 is adapted to partially pass through the positioning hole 531 to realize the positioning between the elastic member 5 and the first housing 11.

[0067] In this embodiment, the elastic element 5 is positioned by the positioning hole 531 and the positioning protrusion structure 114 of the first housing 11. During installation, the positioning protrusion structure 114 passes through the positioning hole 531 so that the elastic element 5 can be installed in place and the elastic element 5 can be accurately connected to the electrode structure 2 and the deformation sensing sheet 3.

[0068] In actual implementation, the first housing 11 is provided with a limiting ring groove 116 corresponding to the connecting ring 53. When installing the elastic member 5, the connecting ring 53 can be limited within the limiting ring groove 116, further realizing the positioning and installation of the elastic member 5 and the first housing 11. Optionally, the positioning hole 531 can be provided on the connecting ring 53, and the positioning protrusion structure 114 can be provided at the bottom of the limiting ring groove 116.

[0069] In one embodiment of the present invention, such as Figure 5 , Figure 6 , Figure 7 , Figure 10 and Figure 11As shown, the first housing 11 is provided with a first opening 118, and the second housing 12 is provided with a second opening 123. The second housing 12 is at least partially inserted into the first opening 118, and the second opening 123 is covered with a sound-permeable membrane 124 to achieve the sealing of the second opening 123.

[0070] In this embodiment, the first housing 11 has a first opening 118 through which a portion of the second housing 12 passes. The second housing 12 passing through the first opening 118 forms a second opening 123. The second opening 123 can be covered by an acoustic membrane 124 to close the second opening 123. The second housing 12 forms a closed space to protect the device located inside the second housing 12. At the same time, the second opening 123 can also serve as an acoustic window. An ultrasonic transducer 6 can be installed inside the second housing 12. The ultrasonic waves emitted by the ultrasonic transducer 6 can be transmitted to the treatment surface of the skin through the acoustic membrane 124. Optionally, the acoustic membrane 124 covers both the second opening 123 and the first opening 118.

[0071] In practice, the treatment head 100 also includes an ultrasonic transducer 6, which is installed inside the second housing 12 and is adapted to emit ultrasonic energy through the second opening 123. Thus, the treatment head 100 can perform ultrasonic treatment on the skin.

[0072] Optionally, the electrode structure 2 is arranged around the first opening 118. When the electrode structure 2 comes into contact with the treatment surface of the skin, the control board 4 can also control the working state of the ultrasonic transducer 6 according to whether the deformation sensing sheet 3 is deformed. When the deformation sensing sheet 3 is deformed, the control board 4 can control the ultrasonic transducer 6 and the electrode structure 2 to start working. In this way, the treatment head 100 can simultaneously perform ultrasonic treatment and radiofrequency treatment on the treatment surface of the skin.
