A heat radiation fan 18 is also arranged in the handle 1, and a heat radiation hole 19 is arranged on the outer wall of the handle 1 close to the heat radiation fan 18.

The host 3 is further internally provided with a pressure sensor 32 and a pressure relief valve 34, the pressure sensor 32 and the pressure relief valve 34 are respectively connected with the negative pressure pipeline, and pressure data of the pressure sensor 32 is displayed on the display panel 31, so that the pushing action of the linear driver 11 and the pushing depth of the radio frequency microneedle device 21 can be conveniently determined through the data. If a button switch is arranged on the handle to control the linear driver to push out the needle, on one hand, a doctor can have one more button pressing action during each cycle of treatment, and one treatment basically needs hundreds of cycles, and on the other hand, the doctor holds the handle by hands and then presses the button by one finger, so that the microneedle handle can slightly shake, microneedles inserted into the skin are stirred in the skin, and pain is caused. Therefore, the radio frequency micro-needle handle device liberates the hands of a doctor clinically and facilitates better treatment work.

In addition, a reset spring 22 is installed inside the microneedle electrode 2, two reset springs 22 are provided and installed on two sides of the radio frequency microneedle device 21, and the microneedle electrode 2 is elastically connected with the radio frequency microneedle device 21 through the reset springs 22.

After the micro-needle is pushed back to the initial position, the needle tip can retract inside the shell, so that the phenomenon that the needle pricks the skin by misoperation during non-treatment to cause cross infection is prevented; on the other hand, the device has the function of protecting the needle tip of the microneedle, and prevents the needle tip from being knocked out of the barb, so that the pain of the patient during treatment is improved.

The working end of the microneedle electrode 2 is provided with a negative pressure cavity which is of a closed loop type, such as a circular type or a loop type or a square frame type. The handle 1 is internally provided with a negative pressure pipeline communicated with the negative pressure cavity, the host machine 3 is internally provided with a negative pressure pump 33, and the input end of the negative pressure pump 33 is connected with the negative pressure pipeline. The negative pressure pump 33 operates to suck up the gas in the negative pressure chamber, thereby sucking up the skin. The negative pressure adsorption has the effect that the skin wrapped around the inner folds can be pulled flat through the negative pressure cavity, so that the matrix microneedles are conveniently penetrated, the penetrating depth meets the preset value, and a good treatment effect is obtained. In addition, the micro-needle in the radio frequency micro-needle device 21 is an insulating needle, the surface of the needle body is insulated, and only the needle point is connected with a power supply, so that the surface layer is protected and is not burnt by heat.

As a preferable scheme, specifically, a negative pressure groove 23 is formed at the periphery of the working end of the microneedle electrode 2, a negative pressure cavity is formed inside the negative pressure groove 23, and the negative pressure groove 23 is of a closed ring type, so that when the microneedle stimulates the skin, the periphery of the portion of the skin to be stimulated is adsorbed, the epidermis of the skin is flattened, and the microneedle can penetrate the skin uniformly.

Further, the negative pressure groove 23 has a frame-like structure at the end of the microneedle electrode 2, and the section of the negative pressure groove 23 is any one of U-shaped, V-shaped, and semicircular, so that the suction effect can be achieved.

The negative pressure + the friction force between the skin and the negative pressure groove is larger than the force of the skin for resisting bending deformation, so that the skin can be sucked tightly, and the calculation formula is as follows:

F＝C*(p*L+μ*p*L*cos(α/2)-12EI*(π-α)/L3)

wherein, the circumference of the center line of the C-shaped annular negative pressure groove; p-negative pressure; l-negative pressure groove width; mu-coefficient of friction between skin and negative pressure sink; alpha-negative pressure groove included angle; EI-skin bending stiffness.

When F is larger than 0, the skin can be sucked tightly, and the larger the F is, the larger the adsorption force value is. On the premise of satisfying the above formula, the smaller the negative pressure value is, the better the comfort level of skin adsorption is, and the less the amount of bleeding is sucked out when the micro needle is pierced.

When the method is implemented, the notch of the negative pressure groove 23 is provided with an opening angle of 3-45 degrees, and the width of the negative pressure groove can be 1-5mm according to actual needs. The purpose of the opening angle setting is to reduce the negative pressure value of negative pressure adsorption under the condition of not influencing the effect of adsorbing and tightly sucking the skin. Reducing the negative pressure can improve the comfort of skin adsorption (the greater the negative pressure, the more severe the pain), while the smaller the negative pressure can reduce the amount of bleeding that the skin experiences when the micropores are punctured. The width of the negative pressure groove 23 is set according to actual needs during microneedle therapy because the thickness of the dermis layer of the skin at different positions is different, and the negative pressure is different during adsorption.

In specific implementation, a connecting part 14 is arranged on the outer wall of the side of the handle 1 close to the microneedle electrode 2, and a negative pressure pipe joint 15 is arranged inside the connecting part 14. The negative pressure pipe joint 15 is of an L-shaped structure or is a straight pipe which is obliquely installed, so that a negative pressure pipeline is conveniently led into the handle from the outside of the handle 1, and the handle device is convenient to hold and carry due to the fact that the handle device is integrated.

The input end of the negative pressure pipe joint 15 is connected with the negative pressure cavity through the first air pipe 24, the output end of the negative pressure pipe joint 15 is connected with the negative pressure pump 33 through the second air pipe 36, and the first air pipe 24 and the second air pipe 36 are hoses and form a negative pressure pipeline. When the first air conveying pipe 24 and the second air conveying pipe 36 are installed, the first air conveying pipe and the second air conveying pipe are in the form of hose cover hard rubber joints, the disassembly is convenient, disposable replacement consumables can be made conveniently, and cross infection among patients is avoided.

The first air pipe 24 is provided with a hydrophobic vent valve 25, the hydrophobic vent valve 25 is a hydrophobic automatic exhaust valve, and the connection between the hydrophobic vent valve and the first air pipe 24 also adopts a hose sleeve hard rubber joint mode and has a structure convenient to disassemble. The negative pressure pipeline contains the disposable hydrophobic vent valve 25, the skin punctured by the micro-needle can be sucked in the negative pressure adsorption process, micro blood flows out, the hydrophobic vent valve 25 can prevent the blood from being sucked into the negative pressure pump to damage the negative pressure pump, and meanwhile, cross infection among patients is avoided.

The specific working process of the radio frequency microneedle handle device is as follows: after the main machine 3 is connected with a power supply, the linear driver 11 in the handle 1 automatically finds a zero point by the micro switch 13 and stops at the zero point for waiting for an instruction. During treatment, the handle 1 is vertically placed on the surface of skin, the end face of the microneedle electrode 2 is tightly attached to the skin, the negative pressure pump 33 in the host 1 is connected to the U-shaped negative pressure groove 23 of the microneedle electrode 2 through the second air conveying pipe 36, the negative pressure pipe joint 15, the hydrophobic air permeable valve 25 and the first air conveying pipe 24, and the skin in a treatment area is adsorbed into the U-shaped groove 23 and fixed through negative pressure adsorption, so that the skin in the treatment area is tightly attached to the end face of the microneedle electrode 2. When the pressure sensor 32 in the host 3 detects that the negative pressure value reaches a preset value, the linear driver 11 is triggered to push a set distance outwards (or the switch key 16 is manually pressed to send a push instruction to the linear driver 11), and the push rod 12 transmits motion to the radio frequency micro-needle device 21, so that the micro-needles in the radio frequency micro-needle device 21 penetrate into the skin after being withdrawn. After the puncture is finished, the end of the micro needle point reaches the target tissue, the radio frequency power supply in the host 3 releases radio frequency energy through the radio frequency micro needle device 21, and acts on the target tissue for a preset time, so that the target tissue is reversibly damaged. After the radio frequency energy output is finished, the pressure release valve 34 is opened, the negative pressure value in the U-shaped groove 23 is removed, the linear driver 11 drives the push rod 12 to recover, the radio frequency microneedle device 21 retracts into the inner cavity of the microneedle electrode 2 under the action of the return spring 22, and at the moment, a treatment cycle is finished.

The treatment principle of the radio-frequency microneedle handle device is as follows: by combining the insulating micro-needle and the radio frequency technology, radio frequency energy precisely acts on target tissues through the tip end of the micro-needle, reversible thermal damage is generated only on the dermis layer, and thermal damage to the epidermis is avoided. The dermis layer is heated to an ideal temperature through radio frequency, reversible damage is generated on the dermis layer, and collagen and elastin in the skin are stimulated to be recombined and regenerated, so that the purposes of tightening the skin and reducing wrinkles are achieved.
