The conductive needle body is divided into multiple radio frequency emission segments. The microneedles are inserted into the skin at different depths by an electric push rod and a transmission rod, forming a circuit for layered discharge and avoiding damage to the skin surface.
This technology enables layered radiofrequency treatment at different skin depths, avoiding damage to the surface skin and reducing production difficulty and cost.

The transmission rod 2 can move relative to the needle holder 5, and the needle holder 5 can move relative to the protective cover 9. The forty-nine layered microneedles 7 are vertically installed on the circuit board 6, and four conductive rods 4 are arranged on the back of the circuit board 6, which protrude out from the back of the protective cover 3 through the needle holder 5. The forty-nine layered microneedles 7 are arranged in seven columns and seven rows in array. Each column of negative needles 72 is located between two columns of positive needles 71. Forty-nine needle holes 901 are arranged on the protective cover 9, and the forty-nine needle holes 901 correspond to the forty-nine layered microneedles 7 one by one. The forty-nine layered microneedles 7 can all pass through the forty-nine needle holes 901. The four reset springs 8 are arranged around the forty-nine layered microneedles 7. One end of the four reset springs 8 is installed on the needle holder 5, and the other end of the four reset springs 8 abuts against the inner wall of the protective cover 9 when the layered microneedles 7 pass through the needle holes 901.
[0027] The motor push rod 1 can be purchased in the market to provide power for the forward and backward movement of the layered microneedles 7 and control the depth of the layered microneedles 7 inserted into the skin 10. The transmission rod 2 plays a transmission role. The protective shell is used to protect the internal parts and move relative to the layered microneedles 7. The conductive rod 4 is used to connect the positive and negative poles of the external power supply and transmit electric energy to the circuit board 6. The needle holder 5 is used to fix the circuit board 6 on the transmission rod 2 to increase the stress area. The circuit board 6 is used to distribute the forty-nine layered microneedles 7 and control the output power of the layered microneedles 7. The layered microneedles 7 can form a loop under the skin 10 to discharge and realize layered discharge in the skin 10, and can avoid damage to the surface of the skin 10. The reset spring 8 makes the layered microneedles 7 exit from the skin 10 and retract into the protective cover 9; the conductive rod 4 is used to connect the external power supply and transmit the power supply to the circuit board 6.
[0028] AsFigures 4-6 As shown in the figure, each positive needle 71 or negative needle 72 includes a conductive needle body, a needle insulation layer 702 and four insulation separation layers 704. The needle insulation layer 702 covers the rear part of the conductive needle body, and the needle insulation layer 702 divides the conductive needle body into a conductive needle end 701 and a treatment section. The conductive needle end 701 is located at the rear end of the conductive needle body, used for mounting on the circuit board 6 and enabling the circuit board 6 to supply power to the conductive needle body. The treatment section is located at the front end of the conductive needle body, and the most front end of the treatment section is the needle tip (also the RF emitting section 703). The four insulation separation layers 704 divide the treatment section into five RF emitting sections 703, and the length of the RF emitting section 703 is 0.4mm.
[0029] The conductive needle body is made of stainless steel, and its diameter is 0.15mm, which is the main body of the positive needle 71 or the negative needle 72, used for conducting electricity and piercing into the skin 10. The needle insulation layer 702 is used to insulate part of the conductive needle body, which can avoid burning the skin 10 when electrified. The length of the insulation separation layer 704 is 0.25mm, which is used to divide the treatment section into multiple RF emitting sections 703 to achieve layered transverse RF treatment in the skin 10, and when the insulation separation layer 704 is located on the surface of the skin 10, it can avoid the layered microneedle 7 from burning the skin 10 when electrified. The length of the RF emitting section 703 is 0.4mm, which is used for discharging in the skin 10 tissue.
[0030] Working principle explanation: as shown in the figure, Figure 7 According to the treatment depth requirement, the electric push rod 1 pushes the transmission rod 2 to pop out, the transmission rod 2 pushes the needle holder 5 to move outward relative to the protective cover 9, the layered microneedle 7 is pushed out from the protective cover 9 and pierced into the skin 10, and stops after being inserted into the skin 10 to the set depth. At this time, the insulation separation layer 704 or one or more sections of the needle insulation layer 702 are located on the surface of the skin 10, and the RF emitting section 703 cannot be in the skin 10, thereby avoiding the RF emitting section 703 from burning the skin 10 when electrified. The multiple RF emitting sections 703 of the positive needle 71 and the RF emitting sections 703 of the multiple negative needles 72 form a loop inside the skin 10 tissue to achieve layered discharge, realizing transverse RF treatment effect on different layers of the skin of the human body.
