On the other hand, the RF electrode cartridge 100 for cosmetic skin treatment having a curved RF electrode according to the present invention has an RF electrode body 120 on the upper surface of the cartridge casing 110, that is, the upper surface of the second casing portion 200b. An electrode on/off switch 115 for turning on/off the electric power applied to ) is located.

The electrode on/off switch 115 includes a switch button 115a elastically supported by a switch spring 115b, so that the switch button 115a is pressed and applied to the RF electrode body 120 only when the electric power is applied. is turned on, and the electrical power is turned off when the pressed state of the switch button 115a is released.

In addition, inside the handpiece body casing 200, that is, inside the cartridge insertion portion 200b, when the cartridge coupling block 210 is pressed and moved, the electrode on-off switch 115 is pressed by pressing the protrusion 241 for pressing the switch is positioned to protrude.

The switch pressing protrusion 241 is placed in contact with the upper surface of the switch button 115a in a state in which the RF electrode cartridge 100 is coupled to the handpiece body casing 200.

More specifically, on the upper surface of the cartridge casing 110, that is, on the upper surface of the second casing portion 200b, a switch mounting protrusion 116 on which the electrode on/off switch 115 is located on the upper surface is positioned to protrude, and the cartridge is inserted. A protrusion inserting portion 240 into which the switch mounting protrusion 116 is inserted is positioned inside the portion 200b, and a protrusion for pressing a switch 241 protrudes from an upper surface of the protrusion inserting portion 240 .

The electrode on/off switch 115 is positioned so that the upper surface of the switch button 115a protrudes to the upper surface of the switch mounting protrusion 116 or is flush with the upper surface of the switch protrusion, and the RF electrode cartridge 100 is placed on the handpiece body casing ( 200), the switch mounting protrusion 116 is inserted into the protrusion insert 240, and the switch pressing protrusion 241 is placed in contact with the upper surface of the switch button 115a.

That is, when the operator holds the handpiece body casing 200 and presses the handpiece body casing 200 while the RF electrode body 120 is in close contact with the skin, the RF electrode cartridge 100 is pushed and the handpiece body casing 200 While moving to, the cartridge coupling block 210 is pressed and moved, and accordingly, the switch mounting protrusion 116 applies electric power to the RF electrode body 120 while pressing the switch button 115a.

In addition, if the handpiece body casing 200 is not pressed while the RF electrode body 120 is in contact with the skin, that is, if the operator does not press the handpiece body casing 200, the cartridge is coupled by the cartridge spring member 220 While the block 210 is moved to the original position, the switch button 115a also returns to the original position by the elastic restoring force of the switch spring 115b to cut off the electric power supplied to the RF electrode body 120, and accordingly, the RF electrode body ( 120) is also turned off.

In the handpiece for cosmetic skin treatment according to the present invention, electric power is applied to the RF electrode body 120 only while the operator holds and presses the handpiece body casing 200 during the procedure, and the operator presses the handpiece body casing 200 during the procedure. ) When the pressed force is released, the electric power applied to the RF electrode body 120 is automatically cut off by the elastic restoring force of the spring, so that the correct number of treatments can be performed in the required area, and skin damage due to excessive stimulation during treatment accidents can also be prevented.

The RF electrode cartridge 100 for skin cosmetic treatment having a curved RF electrode according to the present invention and the handpiece for skin cosmetic treatment having the same are operated while moving the RF electrode body 120 in close contact with the patient's skin. do.

At this time, the first casing portion 110a of the RF electrode cartridge 100 is freely tilted in a radius of 360 degrees around the ball joint portion 140 so that the RF electrode body 120 is continuously maintained in close contact with the skin. make it possible

In addition, by generating a massage effect on the skin through vibration by the vibration motor unit, a treatment effect according to the procedure is further induced.

In addition, the pressing force applied by the operator is elastically supported and buffered by the spring member 220 for the cartridge, and the elastic restoring force of the spring member 220 for the cartridge ensures that the RF electrode body 120 is in close contact with the skin. can be maintained.

In the present invention, the RF electrode body 120 is moved in close contact with the skin while being freely tilted in a radius of 360 degrees around the ball joint unit 140 during the procedure, so that the RF electrode body 120 is spaced apart from the skin, thereby reducing the damage of the skin tissue. It greatly improves safety during procedures by preventing accidents that cause damage or burns to the skin.

The present invention forms an RF electrode body that is in contact with the skin into a curved surface so that it can be effectively adhered to the skin even when pressed with a small force during the procedure, thereby improving the treatment effect, obtaining even and uniform treatment effects during skin treatment, and treatment It can minimize discomfort to critical patients and greatly improve satisfaction during the procedure.

In the present invention, the relay 190 for controlling the electrical signal applied to the RF electrode is placed on the RF electrode cartridge, and when the RF electrode cartridge is replaced, the relay 190, which is a consumable part, is also replaced to replace the handpiece body casing 200. Since it can be used without the handpiece body casing 200, it is possible to reduce the hassle and cost of replacing the handpiece body casing 200.

The present invention can minimize the pain generated during skin treatment and improve the treatment effect by providing a vibration motor.

In the present invention, electric power is applied to the RF electrode body 120 only when the RF electrode cartridge in contact with the skin is pressed, enabling safe and simple treatment and improving safety during treatment.
