Description

Technical Field

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

[0002] Radio frequency (RF) is a high-frequency alternating electromagnetic wave that falls between amplitude-modulated (AM) and frequency-modulated (FM) radio waves. Its energy exists and propagates in space in the form of electricity or magnetism (waves). Its frequency range is very wide, ranging from hundreds of kHz to hundreds of MHz.

[0003] The mechanism of radiofrequency heating primarily depends on the operating frequency of the radiofrequency device, delivering radiofrequency energy to the subcutaneous layer at least to the dermis depth: ionic currents are generated by the displacement of charged particles in an alternating electromagnetic field, or by the rotation of polar water molecules in an alternating electromagnetic field. Both phenomena interact with the affected particles and biological tissue, leading to volumetric dissipation of electromagnetic energy, thereby heating and raising the temperature of the biological tissue at the target depth. Common non-invasive radiofrequency therapy devices, when applied directly to the skin for radiofrequency heating, often struggle to maintain proper adhesion. Applying excessive pressure is also unsuitable for treating sensitive areas, such as the eye area, as it can cause discomfort or even damage to the eyeball.

[0004] However, the pressure of current treatment devices is usually controlled by physicians, which makes precise control impossible and can easily lead to discomfort or even injury for patients during treatment. Utility Model Content

[0005] The main purpose of this invention is to propose a treatment head and device that uses negative pressure, which aims to make the pressure of the treatment head easy to control during treatment, so as to reduce the discomfort of patients during treatment.

[0006] To achieve the above objectives, this utility model proposes a treatment head, the treatment head comprising:

[0007] case;

[0008] An electrode section is located at the end of the housing;

[0009] The housing is further provided with a negative pressure section, the outlet of which is located at the end of the housing and surrounds the electrode section; the negative pressure output from the outlet of the negative pressure section abuts against the end of the housing and keeps the electrode section and the treatment section in contact with each other.

[0010] In one embodiment, the electrode portion includes a treatment electrode and a frame made of an electrically insulating material, with the skin-facing end face of the treatment electrode exposed through the inner edge of the frame. When the negative pressure output from the outlet of the negative pressure portion keeps the electrode portion in contact with the treatment site, electromagnetic energy from the end face of the treatment electrode is delivered to the tissue via the skin surface.

[0011] In one embodiment, the housing is further provided with a cold spray section and a discharge section. The back side of the treatment electrode, which is disposed opposite to the end face, forms a cooling cavity. The cold spray section includes a delivery path for spraying cooling medium that communicates with the cooling cavity. The discharge section is connected to the cooling cavity and includes a discharge path that discharges the cooling medium that has gathered in the cooling cavity to the outside of the housing.

[0012] When the negative pressure output from the outlet of the negative pressure section keeps the electrode section and the treatment area in contact with each other, the cooling medium is gathered into the cooling cavity through the conveying path to cool the treatment electrode and indirectly cool the treatment area.

[0013] In one embodiment, the treatment head further includes a pressure sensor disposed at the end of the housing, for detecting the pressure applied to the electrode by the treatment site when the negative pressure output from the outlet of the negative pressure section adsorbs the treatment site and the electrode is in contact with the treatment site.

[0014] In one embodiment, the treatment head further includes a filter disposed in the negative pressure section for filtering air entering the negative pressure section through its outlet.

[0015] In one embodiment, the electrode portion is flush with the end face of the housing; or

[0016] The electrode portion is recessed into the end face of the housing.

[0017] This utility model also proposes a therapeutic device, the therapeutic device comprising:

[0018] Vacuum pump module;

[0019] The treatment head as described above; wherein the outlet of the vacuum pump module is connected to the inlet of the negative pressure section.

[0020] In one embodiment, the therapeutic device further includes a controller; the controller is electrically connected to the vacuum pump module, and the controller is used to acquire the pressure value detected by the pressure sensor and control the vacuum pump module to output a negative pressure value related to the pressure value.

[0021] In one embodiment, the vacuum pump module includes a vacuum pump and an electromagnetic proportional valve connected to the vacuum pump; the controller is further configured to compare the pressure value of the pressure sensor with a preset range and control the negative pressure range output by the electromagnetic proportional valve.

[0022] When the pressure value of the pressure sensor is within a preset first pressure range, the electromagnetic proportional valve is controlled to open at a preset fine opening degree related to the first pressure range.

[0023] When the pressure value of the pressure sensor is within a preset second pressure range, the electromagnetic proportional valve is controlled to open horizontally at a preset half-opening degree related to the second pressure range;

[0024] When the pressure value of the pressure sensor is within a preset third pressure range, the electromagnetic proportional valve is controlled to open horizontally to a preset full opening degree related to the third pressure range.

[0025] Wherein, the first pressure range is greater than the third pressure range, and the second pressure range is located between the first pressure range and the third pressure range.

[0026] In one embodiment, the controller controls the negative pressure value output by the vacuum pump module to be inversely proportional to the pressure value detected by the pressure sensor.

[0027] In one embodiment, the controller is further configured to set a minimum pressure threshold for the pressure sensor, and when the pressure value of the pressure sensor is equal to or less than the minimum pressure threshold, the controller controls the vacuum pump module to stop operating.

[0028] In one embodiment, the controller is further configured to acquire the pressure value of the treatment site applied by the electrode through the pressure sensor, and use the pressure value as the tolerance pressure value of the treatment site applied by the electrode. When the electrode applies to the treatment site again, the controller controls the negative pressure value output by the vacuum pump module so that the pressure value of the pressure sensor is less than or equal to the tolerance pressure value.

[0029] The technical solution of this utility model includes a treatment head comprising a housing for connection to a handle. During treatment, the end of the housing abuts against the treatment area, and the electrode portion located at the end of the housing contacts the treatment area, transmitting radiofrequency energy to the skin tissue to achieve the therapeutic effect. The housing also contains a negative pressure section for the flow of negative pressure airflow, and the outlet of the negative pressure section is also located at the end of the housing, surrounding the electrode portion. When the electrode portion contacts the treatment area, the negative pressure section applies negative pressure to the treatment area through the outlet, making the skin smoother and more tightly fitted to the electrode portion, enhancing the therapeutic effect of the radiofrequency energy. The inlet of the negative pressure section can be used to connect to a vacuum pump module built into the treatment device. The inlet of the negative pressure section is annularly arranged to ensure uniform force on the treatment area during treatment, thereby ensuring the therapeutic effect of the treatment head on the treatment area. Utilizing negative pressure adsorption to fix the skin during radiofrequency treatment allows for precise output of radiofrequency energy to the ideal subcutaneous treatment depth, ensuring the effectiveness of the radiofrequency treatment.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

If the specific posture changes, the directional indicators will also change accordingly.

Therefore, 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.

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 utility model.

[0040] Combined with reference Figure 1 and Figure 2 As shown, this utility model proposes a treatment head 100, which includes a housing 1, an electrode part 2, and a pressure sensor 22. The electrode part 2 is located at the end of the housing 1. The housing 1 is also provided with a negative pressure part 3. The outlet of the negative pressure part 3 is located at the end of the housing 1 and surrounds the electrode part 2. The negative pressure output from the outlet of the negative pressure part 3 adsorbs the treatment part against the end of the housing 1 to keep the electrode part 2 and the treatment part in contact with each other.

[0041] In one embodiment, the electrode portion 2 is flush with the end face of the housing 1, such as... Figure 1 As shown, when the outlet of the negative pressure section 3 defined by the end face of the housing 1 adsorbs the skin, it is flush with the electrode section 2; or the electrode section 2 is recessed in the end face of the housing 1 (not shown), and when the outlet of the negative pressure section 3 defined by the end face of the housing 1 draws the skin into the housing 1 and it is flush with the electrode section 2.

[0042] In some embodiments of this application, during treatment, the end of the housing 1 abuts against the treatment site, and the electrode portion 2 located at the end of the housing 1 contacts the treatment site, transmitting radiofrequency energy to the skin tissue to achieve the therapeutic effect. The housing 1 also includes a negative pressure section 3 through which negative pressure airflow can circulate. The outlet of the negative pressure section 3 is also located at the end of the housing 1, and the outlet of the negative pressure section 3 is arranged around the electrode portion 2. When the electrode portion 2 contacts the treatment site, the negative pressure section 3 applies negative pressure to the treatment site through the outlet, making the skin smoother and more tightly fitted to the electrode portion 2, thus enhancing the therapeutic effect of the radiofrequency energy. It is understood that the inlet of the negative pressure section 3 can be used to communicate with the vacuum pump module 7 built into the treatment device. The inlet of the negative pressure section 3 is arranged in a ring shape to ensure that the treatment site is subjected to uniform force during treatment, thereby ensuring the therapeutic effect of the treatment head 100 on the treatment site. When the negative pressure unit 3 applies negative pressure to the treatment site, the pressure sensor 22 located at the end of the housing 1 can detect the pressure applied to the end of the housing 1 by the treatment site in real time, so that the physician can accurately understand the contact pressure between the treatment head 100 and the treatment site and judge the pressure condition of the treatment site.

[0043] In embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the electrode part 2 includes a treatment electrode 21 and a frame 24 made of an electrically insulating material. The skin-facing end face of the treatment electrode 21 is exposed through the inner edge of the frame 24. When the negative pressure output from the outlet of the negative pressure part 3 keeps the electrode part 2 in contact with the treatment site, the electromagnetic energy from the end face of the treatment electrode 21 is delivered to the tissue through the skin surface.

[0044] In this embodiment, the electrode part 2 is disposed at the end of the treatment head and is a flexible electrode structure, including a treatment electrode 21 and a frame 24 made of an electrically insulating material. The end face of the treatment electrode 21 facing the skin is exposed through an opening at the inner edge of the frame 24. The negative pressure output from the outlet of the negative pressure part 3 keeps the electrode part in contact with the treatment site while delivering electromagnetic energy from the end face of the treatment electrode 21 through the skin to the tissue. The frame 24 provides stable support and fixation for the treatment electrode 21. The frame 24 is then covered with a thin film with good insulation and flexibility, such as a polyimide polymer film, which also prevents the treatment electrode 21 from directly contacting the skin, avoiding skin burns caused by overheating of the treatment electrode 21, and allowing energy to be more evenly distributed in the skin tissue.

[0045] The frame 24, treatment electrode 21, and polyimide polymer film are integrally molded and can further integrate sensors, such as pressure and temperature sensors. These sensors can promptly alert the user and adjust energy output when the temperature is abnormal, preventing overheating and skin damage. The pressure sensor can prevent skin damage caused by uneven contact between the treatment head and the skin or excessive pressure. The treatment electrode 21 can be a conductive layer, applied to an opening on the inner edge of the frame 24 with its surface exposed.

[0046] In the prior art, when the treatment head 100 and the handle are connected, the treatment electrode 21 is electrically connected to the control device inside the handle. The physician controls the force of the handle and treatment head 100 against the skin and sets different treatment parameters to adapt to different treatment needs.

[0047] In one embodiment, the treatment head further includes a pressure sensor 22, which is disposed at the end of the housing 1 and is used to detect the pressure applied to the electrode part 2 by the treatment part when the electrode part 2 is kept in contact with the treatment part.

[0048] Physicians can control the negative pressure output of the negative pressure unit 3 based on the pressure value detected by the pressure sensor 22, thereby controlling the pressure between the treatment site and the electrode unit 2 to adapt to different treatment needs, different treatment sites and individual differences of patients, and avoid excessive pressure causing discomfort or even damage to the treatment site of the patient, or insufficient pressure affecting the treatment effect.

[0049] Optionally, the pressure sensor 22 can be a high-precision miniature pressure sensor 22 to accurately detect the pressure on the electrode portion 2. In this embodiment, the pressure sensor 22 can be directly contacted with the treatment site to detect the pressure on the treatment site in real time during treatment. The pressure sensor 22 can be integrated into the electrode portion 2, and the pressure on the treatment site can be directly determined by detecting the pressure on the electrode portion 2.

[0050] In embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the housing 1 is also provided with a cold spray section 4 and a discharge section. The back side of the treatment electrode 21 forms a cooling cavity 42, wherein the back side and the end face are arranged opposite to each other. The cold spray section 4 includes a delivery path for spraying cooling medium that connects to the cooling cavity 42. The discharge section is connected to the cooling cavity 42 and includes a discharge path that discharges the cooling medium that gathers in the cooling cavity 42 to the outside of the housing 1.

[0051] In this process, the negative pressure output from the outlet of the negative pressure section 3 keeps the electrode section 2 and the treatment area in contact with each other, and the cooling medium is gathered into the cooling cavity 42 through the transport path to cool the treatment electrode 21 and indirectly cool the treatment area.

[0052] In this embodiment, during radiofrequency treatment, the cooling medium can pass through the cold spray section 4 to the cooling cavity 42 to cool the treatment electrode 21, thereby cooling the treatment site and preventing adverse reactions such as skin burns caused by excessive heat generated by radiofrequency energy.

[0053] Specifically, the main unit of the therapeutic device is equipped with a cold spray source. When the treatment head 100 is connected to the handle, the cold spray pipe inside the handle is connected to the inlet of the cold spray section 4 inside the treatment head 100. The cold spray source passes through the cold spray pipe inside the handle and reaches the back of the treatment electrode 21 of the treatment head 100. The cold spray source provides a stable flow of cooling medium to the cold spray section 4. Optionally, the cold spray section 4 is also equipped with a cooling channel 41 and a cooling cavity 42. The cooling channel 41 and the cooling cavity 42 form a transport path for the cooling medium. The cold spray source sprays the cooling medium into the cooling cavity 42 through the cooling channel 41, indirectly cooling the treatment area.

[0054] Optionally, the inlet of the cooling channel 41 is flared to facilitate the entry of the cooling medium, and the outlet of the cooling channel 41 is constricted to allow the cooling medium to enter the cooling cavity 42 in a mist form, thereby improving the cooling effect on the treatment site and preventing adverse reactions. Optionally, the cross-sectional area of ​​the cooling cavity 42 is larger than that of the cooling channel 41, so that the cooling medium gathered in the cooling cavity 42 fully contacts the back of the treatment electrode 21, ensuring the cooling effect on the treatment site.

[0055] In this embodiment, the discharge section can discharge the cooling medium that has accumulated in the cooling cavity 42, while new cooling medium flows in from the inlet of the cold spray section 4, thereby ensuring that there is a continuous low-temperature cooling medium in the cooling system to cool the treatment electrode 21 and maintain a suitable temperature at the treatment site.

[0056] Specifically, the inlet of the discharge section is connected to the cooling cavity 42, and the outlet of the discharge section is connected to the external environment, so as to discharge the cooled cooling medium from the treatment head 100. The delivery path of the discharge section can be formed by the assembly gap or reserved channel inside the treatment head 100.

[0057] Optionally, when the cooling cavity 42 is covered by the treatment electrode 21, the inlet of the discharge section is located in the cooling cavity 42. The cooling medium is sprayed from the outlet of the cooling channel 41, moves into the cooling cavity 42, and after being reacted by the treatment electrode 21, moves back into the inlet of the discharge section and is discharged from the outlet of the discharge section. Optionally, the inlet of the discharge section and the outlet of the cooling channel 41 are arranged parallel and spaced apart; the inlets of the discharge section include multiple inlets, and the outlets of the cooling channel 41 are located between the multiple inlets of the discharge section. Optionally, the electrode section 2 also includes a temperature sensor 23, which is used to detect the temperature of the treatment site. The cold spray source can control the flow rate of the cooling medium according to the temperature value detected by the temperature sensor 23 to keep the temperature of the treatment site within a preset range, avoiding excessively high or low temperatures of the treatment site, which could cause discomfort to the patient.

[0058] In embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the treatment head 100 also includes a filter 5, which is disposed in the negative pressure section 3 and is used to filter the air entering the negative pressure section 3 through the outlet of the negative pressure section 3.

[0059] In this embodiment, the filter 5 is provided to prevent impurities drawn in by negative pressure from entering the vacuum pump module 7 of the handle along the negative pressure section 3, thereby affecting the normal operation and service life of the vacuum pump module 7.

[0060] In actual implementation, the treatment head 100 also includes a connector 6, which is located inside the housing 1. The connector 6 provides mounting and support for the electrical connection structure of the treatment head 100, such as electrical contacts or electrical prongs. The connector 6 also has a snap-fit ​​structure or a screw hole. During the assembly of the treatment head 100 and the handle, the connector 6 achieves a mechanically detachable connection with the treatment head 100 through the snap-fit ​​structure or screw hole. The electrical connection structure of the treatment head 100 is also connected to the corresponding electrical connection structure of the handle to achieve electrical connection between the treatment head 100 and the handle. The cold spray section 4 and the negative pressure section 3 are also at least partially located on the connector 6. Thus, when the treatment head 100 and the handle are connected, the inlet of the cold spray section 4 and the inlet of the negative pressure section 3 are respectively connected to the cold spray pipe inside the handle and the vacuum pump module 7 inside the main unit to achieve pneumatic connection between the treatment head 100, the handle, and the main unit of the treatment device.

[0061] Specifically, the negative pressure section 3 is arranged in three sections, including a first section 31, a second section 32, and a third section 33. The first section 31 is disposed on the housing 1, the third section 33 is disposed on the connector 6, and the filter 5 is disposed in the second section 32. The two ends of the second section 32 are detachably connected to the first section 31 and the second section 32, respectively, so as to facilitate the connection or disconnection of the filter 5 from the negative pressure section 3. The end of the first section 31 away from the third section 33 is provided with the outlet of the negative pressure section 3, and the end of the third section 33 away from the first section 31 is provided with the inlet of the negative pressure section 3.

[0062] Optionally, the first segment 31 is integrally formed with the housing 1, and the third segment 33 is integrally formed with the connector 6. Optionally, the filter 5 is a filter sponge.

[0063] Optionally, the electrode portion 2 is flush with the end face of the housing 1, such as... Figure 1 As shown, when the outlet of the negative pressure section 3 defined by the end face of the housing 1 adsorbs the skin, it is flush with the electrode section 2. The negative pressure section 3 forms a negative pressure cavity 34 at the outlet end. The negative pressure cavity 34 is arranged in a ring shape so that the negative pressure can be evenly applied to the area around the treatment site to make the treatment site fit parallel to the electrode section 2, so as to ensure that the electromagnetic energy is delivered to the tissue at the target depth through the skin surface.

[0064] In an alternative embodiment, the electrode part 2 is recessed into the end face of the housing 1 (not shown). In this case, the outlet of the negative pressure part 3 defined by the end face of the housing 1 is a circular opening, which draws the entire treatment area into the housing 1 and flush with the electrode part 2, so that the negative pressure can be applied to the treatment area over a large area. The entire treatment area is confined within the negative pressure cavity 34, preventing the skin and the electrode part 2 from sliding against each other, so as to ensure that electromagnetic energy is delivered to the target tissue through the skin surface.

[0065] This utility model also proposes a therapeutic device, such as Figures 1 to 3 As shown, the therapeutic device includes a vacuum pump module 7, a treatment head 100, and a handle housed within the main unit. The specific structure of the treatment head 100 is as described in the above embodiments. Since this therapeutic device adopts all the technical solutions of all the above embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated upon here. The handle is equipped with a controller and is connected to the treatment head 100. The vacuum pump module 7 is connected to the inlet of the negative pressure section 3. The controller is electrically connected to the vacuum pump module 7 and is used to acquire the pressure value of the pressure sensor 22 and control the vacuum pump module 7 to output a negative pressure value related to the pressure value. In some embodiments, the handle can be detachably connected to the treatment head 100 via a snap-fit ​​structure or screws.

[0066] In this embodiment, the user can control the negative pressure value output by the vacuum pump module 7 via the controller. When the pressure sensor 22 detects that the pressure value between the electrode 2 and the treatment site is too low, the negative pressure value output by the vacuum pump module 7 can be increased by the controller, that is, the adsorption force between the outlet of the negative pressure section 3 and the skin can be increased, so that the treatment site fits the electrode 2 more tightly, thereby ensuring the treatment effect of the electrode 2. Conversely, when the pressure sensor 22 detects that the contact pressure between the electrode 2 and the treatment site is too high, the negative pressure value output by the vacuum pump module 7 can be decreased by the controller, that is, the adsorption force between the outlet of the negative pressure section 3 and the skin can be decreased, protecting the treatment site from damage and avoiding patient discomfort. The user can also input a preset value of the pressure detected by the pressure sensor 22 into the controller, and the controller can automatically adjust the negative pressure value output by the vacuum pump module 7 so that the pressure value of the pressure sensor 22 approaches and reaches the preset value.

[0067] It should be noted that the negative pressure value in this application refers to the difference between the atmospheric pressure at the outlet of the negative pressure section 3 and the absolute pressure at the outlet.

[0068] In actual implementation, the main unit of the treatment device is equipped with a display window and control buttons. The display window and control buttons are electrically connected to the controller. The display window is used to display the current working parameters of the treatment head 100, such as the pressure value of the pressure sensor 22, the negative pressure value output by the vacuum pump module 7, the output power of the electrode part 2, the temperature value of the temperature sensor 23, etc. The physician can adjust the working parameters of the treatment head 100 through the control buttons or the UI interface.

[0069] In some embodiments, the controller is also electrically connected to the cold spray source within the main unit of the therapeutic device and to the temperature sensor 23 of the electrode section 2. The user can control the operating power of the cold spray source through the controller to adjust the flow rate of the cooling medium in the cold spray section 4, thereby regulating the operating temperature of the electrode section 2. The temperature sensor 23 detects the operating temperature of the electrode section 2 in real time. The user can also input a preset value for the temperature detected by the temperature sensor 23 into the controller, which can automatically adjust the operating power of the cold spray source to ensure that the operating temperature of the temperature sensor 23 reaches the preset value.

[0070] In embodiments of this utility model, such as Figures 1 to 3As shown, the vacuum pump module 7 includes a vacuum pump 71 and an electromagnetic proportional valve 72 connected to the vacuum pump 71. The controller is also used to compare the pressure value of the pressure sensor 22 with a preset range and control the negative pressure range output by the electromagnetic proportional valve 72. When the pressure value of the pressure sensor 22 is within a preset first pressure range, the controller controls the electromagnetic proportional valve 72 to open horizontally at a preset fine opening degree related to the first pressure range. When the pressure value of the pressure sensor 22 is within a preset second pressure range, the controller controls the electromagnetic proportional valve 72 to open horizontally at a preset half opening degree related to the second pressure range. When the pressure value of the pressure sensor 22 is within a preset third pressure range, the controller controls the electromagnetic proportional valve 72 to open horizontally at a preset full opening degree related to the third pressure range. The first pressure range is greater than the third pressure range, and the second pressure range is located between the first and third pressure ranges.

[0071] In this embodiment, the output end of the vacuum pump 71 is connected to the negative pressure section 3, and the opening degree of the valve port connected to the negative pressure section 3 is adjusted by the electromagnetic proportional valve 72. The larger the opening degree of the electromagnetic proportional valve 72, the stronger the suction effect of the vacuum pump 71 on the airflow of the negative pressure section 3, resulting in a larger output negative pressure value and a greater resistance force between the treatment site and the end point during treatment. Conversely, the smaller the opening degree of the electromagnetic proportional valve 72, the weaker the suction effect of the vacuum pump 71 on the airflow of the negative pressure section 3, resulting in a smaller output negative pressure value and a smaller resistance force between the treatment site and the end point during treatment.

[0072] In this embodiment, the first pressure range, the second pressure range, and the third pressure range detected by the pressure sensor 22 can respectively correspond to the negative pressure values ​​output by the vacuum pump module 7 when the electromagnetic proportional valve 72 is in a fine opening horizontal position, a half opening horizontal position, and a full opening horizontal position.

[0073] Understandably, when a user inputs a preset pressure range into the controller, specifically a first pressure range, the controller automatically adjusts the negative pressure output of the vacuum pump module 7 to a first negative pressure range related to the first pressure range. This means the electromagnetic proportional valve 72 is open at a slight opening to maintain the pressure value of the pressure sensor 22 within the first pressure range during treatment. When the user inputs a pressure value lower than the first pressure range (a second pressure range), the controller automatically adjusts the negative pressure output of the vacuum pump module 7 to a second negative pressure range related to the second pressure range. This means the electromagnetic proportional valve 72 is open at a half-open level to maintain the pressure value of the pressure sensor 22 within the second pressure range during treatment. When the user inputs a pressure value lower than the second pressure range (a third pressure range), the controller controls the negative pressure output of the vacuum pump module 7 to be within the third negative pressure range. This means the electromagnetic proportional valve 72 is fully open to maintain the pressure value of the pressure sensor 22 within the third pressure range during treatment. Physicians can select a first, second, and third pressure range based on the patient's actual treatment area and needs. This ensures treatment effectiveness while reducing patient discomfort. For example, the pressure can be within the first range for abdominal treatment, the second range for facial treatment, and the third range for treatment around the eyes. In practice, the pressure range can be selected based on the user's experience with different pressure ranges for different treatment areas. A fourth preset range can also be set according to treatment requirements. When the pressure sensor 22 is within the fourth pressure range, the controller controls the vacuum pump module 7 to output a negative pressure within the fourth negative pressure range.

[0074] In practical implementation, the electromagnetic proportional valve 72 controls the valve opening degree through a built-in proportional electromagnet. The opening degree of the electromagnetic proportional valve 72 can be controlled through open-loop or closed-loop control. When the electromagnetic proportional valve 72 is controlled through open-loop, the controller controls the input current of the proportional electromagnet according to the preset input pressure value, thereby changing the electromagnetic force of the proportional electromagnet and causing it to displace, thus adjusting the valve opening degree accordingly. When the electromagnetic proportional valve 72 is controlled through closed-loop, the controller can adjust the input current of the proportional electromagnet based on the feedback from the detection value of the pressure sensor 22, causing the proportional electromagnet to displace until the detection value of the pressure sensor 22 is within the preset pressure range.

[0075] In another alternative embodiment of this utility model, such as Figures 1 to 3 As shown, the negative pressure value output by the controller-controlled vacuum pump module 7 is inversely proportional to the pressure value of the pressure sensor 22. Specifically, the greater the pressure value between the treatment head end face and the skin, the tighter the skin is adhered. At this time, the negative pressure value output by the controller-controlled vacuum pump module 7 is smaller, so as to reduce the adhesion force of the negative pressure part 3 to the skin.

[0076] In fact, the greater the negative pressure value output by the vacuum pump module 7, the greater the suction force applied to the skin treatment area, resulting in a higher pressure value from the pressure sensor 22. Conversely, the smaller the negative pressure value output by the vacuum pump module 7, the smaller the suction force on the treatment area, and the lower the pressure value from the pressure sensor 22.

[0077] In this embodiment, the negative pressure value output by the vacuum pump module 7 and the pressure value of the pressure sensor 22 have a one-to-one functional relationship. The functional relationship between the negative pressure value and the pressure value can be pre-input to the controller. Based on this relationship, the controller can automatically convert the preset pressure value into the negative pressure value output by the vacuum pump module 7, and then control the vacuum pump module 7 to output this negative pressure value, so that the pressure value of the pressure sensor 22 reaches the preset pressure value. In actual implementation, due to the influence of multiple factors such as the treatment site and the working environment, the relationship between the pressure value of the pressure sensor 22 and the negative pressure value output by the vacuum pump module 7 may not completely conform to the functional relationship pre-input to the controller. Therefore, the preset pressure value of the pressure sensor 22 is changed to a preset range, and correspondingly, the negative pressure value output by the vacuum pump module 7 is also changed to a negative pressure range, that is, the suction force of the vacuum pump module 7 is adjusted in stages.

[0078] In embodiments of this utility model, such as Figures 1 to 3 As shown, the controller is also used to set the minimum pressure threshold of the pressure sensor 22. When the pressure value of the pressure sensor 22 is equal to or less than the minimum pressure threshold, the controller controls the vacuum pump module 7 to stop running.

[0079] In this embodiment, as the treatment ends and the electrode 2 gradually moves away from the treatment site, the pressure value detected by the pressure sensor 22 gradually decreases. Therefore, by setting a minimum pressure threshold by the controller, it can be determined whether the treatment has ended. When the pressure value detected by the pressure sensor 22 is equal to or less than the minimum pressure threshold, it is determined that the electrode 2 has ended the treatment and moved away from the treatment site. At this time, the controller controls the vacuum pump module 7 to stop running in preparation for the next treatment. This avoids the negative pressure unit 3 directly applying excessive negative pressure to the treatment site during the next treatment, which could cause patient discomfort or damage to the treatment site. It also prevents the negative pressure unit 3 from adsorbing impurities.

[0080] Optionally, the controller can also be set with a maximum pressure threshold, i.e., the pressure value that the skin can tolerate. This can effectively prevent serious damage to the treatment site caused by excessive negative pressure output from the vacuum pump module 7. When the controller senses that the pressure value of the pressure sensor 22 reaches or exceeds the set maximum pressure threshold, the controller immediately stops the negative pressure output to protect the safety of the treatment site. It also provides timely warnings to the physician, allowing the physician to adjust the usage of the treatment head 100 or check for abnormalities during the treatment process.

[0081] In embodiments of this utility model, such as Figures 1 to 3 As shown, the controller is also used to obtain the pressure value of the treatment site where the electrode part 2 acts through the pressure sensor 22, and use the pressure value as the tolerance pressure value of the treatment site where the electrode part 2 acts. When the electrode part 2 acts on the treatment site again, the controller controls the negative pressure value output by the vacuum pump module 7 so that the pressure value of the pressure sensor 22 is less than or equal to the tolerance pressure value.

[0082] In this embodiment, when the electrode 2 is applied to the treatment site again, the controller controls the negative pressure output of the vacuum pump module 7, so that the pressure value of the pressure sensor 22 is less than or equal to the tolerance pressure value. This control method fully considers the differences in pressure tolerance of different treatment sites, as well as the changes in tolerance of the same treatment site at different treatment stages. By memorizing and referencing the tolerance pressure value, the pressure between the electrode 2 and the treatment site can be controlled more precisely, improving the safety and comfort of the treatment, reducing adverse reactions such as pain and skin damage caused by excessive pressure, and ensuring the effective use of radiofrequency energy, thereby improving the treatment effect.

[0083] In practice, different patients and different body parts have varying perceptions and tolerances to negative pressure. Before treatment, the physician can assess whether the current pressure value is within the tolerance range of a particular treatment area based on the characteristics of negative pressure adsorption, such as bruising on the skin surface or the patient's sensations (e.g., significant pain). The controller records the current pressure value detected by the pressure sensor 22 at that treatment area as the maximum pressure value (tolerance pressure value). When treating that area, the controller automatically uses this recorded tolerance pressure value as the threshold for the pressure sensor 22, preventing injury to the patient. Treatment areas can include the area around the eyes, neck, and abdomen.
