[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) A negative pressure roller handle and treatment system can, through the built-in infrared temperature probe, accurately and real-time monitor the temperature change in the treatment area. During actual treatment, different skin types and treatment requirements have different temperature tolerances. This function enables medical staff to promptly understand the skin temperature situation. Once the temperature approaches the threshold that may cause skin damage, corresponding measures can be immediately taken, such as adjusting treatment parameters or pausing treatment, effectively avoiding adverse consequences such as scalding. At the same time, accurate temperature monitoring also helps to ensure the stability of the treatment effect, enabling the treatment to always be carried out in a suitable temperature environment, improving the treatment quality, and enhancing the safety and effectiveness of the treatment process.

[0014] (2) A negative pressure roller handle and treatment system can, through the pressure sensor, real-time monitor the pressure borne by the inhaled skin. Once the pressure exceeds the safe range, the negative pressure part will automatically adjust the air volume to restore the pressure to an appropriate level. This not only avoids skin damage caused by excessive pressure but also prevents motor jamming, reduces the risk of gear slippage of the shaft gear, reduction gear, and driving gear, lowers the equipment maintenance cost, and effectively ensures the smoothness of the treatment process and the service life of the equipment.

[0015] (3) A negative pressure roller handle and treatment system can intelligently and real-time adjust the radio frequency energy output according to the temperature in the treatment area. When the temperature rises, the radio frequency energy is automatically reduced to prevent skin damage due to overheating; when the temperature is low, the radio frequency energy is appropriately increased to ensure the treatment effect. This precise energy adjustment mechanism not only improves the safety of the treatment but also enables the radio frequency energy to better act on the deep skin tissue, promotes the generation of collagen and the tightening and lifting of the skin, enhances the treatment effect, and meets the personalized treatment needs of different patients.

[0016] (4) A negative pressure roller handle and treatment system, the infrared lamp board provides 940-nanometer infrared assisted treatment. Combined with other treatment functions, it further enhances the overall treatment effect, brings a more significant skin improvement experience to patients, and expands the treatment application range of the equipment.

[0017] (5) A negative pressure roller handle and treatment system, the sliding structure design of the button makes the operation of the equipment more simple and fast. Users only need to slide the button along the circular groove of the runway to lock and separate the treatment head from the handle body, reducing the operation difficulty of users, decreasing the possibility of operation errors, and improving the use convenience of the equipment and the user experience.

[0018] (6) A negative pressure roller handle and treatment system. The double locking point design of the treatment head and the handle body significantly enhances the stability and reliability of the device structure. During the use of the device, the locking parts on both sides drive the guide rod, slide and other components through the sliding of the button, thereby achieving a balanced locking of the treatment head and the handle body, ensuring that during the treatment process, even if it is subjected to external vibration or collision, the treatment head will not easily loosen or fall off. This not only ensures the continuity and safety of the treatment, but also reduces the situation of poor treatment effect caused by unstable connection. When the treatment head needs to be replaced, the double locking point design can easily and quickly realize the separation operation, which is convenient for the maintenance and replacement of parts of the equipment and improves the practicality of the equipment.

[0019] (7) A negative pressure roller handle and treatment system, wherein the rotating screen can rotate at multiple angles according to the user's usage habits and operation scenarios, making it convenient for the user to view device information and perform operations in different positions and postures. Whether the user is using the handheld device for treatment or placing the device in a specific position for use, the user can easily adjust the screen angle to obtain the best visual effect, thereby improving the convenience of operation.

[0020] (8) A negative pressure roller handle and treatment system. The roller structure brings better treatment and massage effects. The improved roller surface structure increases the contact area with the skin, making the skin more evenly stressed during treatment and the massage effect more obvious. The optimized gaps on the four sides of the roller prevent the skin from being sucked into the narrow gap and causing strangulation, thereby improving the safety of treatment.

[0021] (9) A negative pressure roller handle and treatment system, wherein the lower end of the radio frequency contact is provided with a V-shaped surface structure connected to the roller. The design of the V-shaped surface structure increases the contact area and contact stability between the radio frequency contact and the roller. Through the action of the compression spring, reliable contact can always be maintained. During the treatment process, stable radio frequency contact ensures stable transmission of radio frequency energy, avoiding energy loss and poor treatment effect caused by poor contact, which makes radio frequency treatment more accurate and efficient, and improves the success rate and stability of treatment.

[0022] (10) A negative pressure roller handle and treatment system, each treatment head is equipped with an identification board that stores a serial number and usage information. This information is read by a spring needle connected to the main control board. The device can automatically identify the model, number of uses, remaining life and other parameters of the treatment head. This helps medical staff to manage the equipment in a refined manner, understand the status of the treatment head in a timely manner, and reasonably arrange maintenance and replacement plans. At the same time, for different types of treatment heads, the device can automatically adjust the corresponding treatment parameters according to the identification information to ensure the accuracy and safety of the treatment, thereby improving the intelligence level and usage efficiency of the equipment.
