The present disclosure relates to an anti-burn RF electrode cartridge for skin care and treatment, and a handpiece for skin care and treatment comprising the same. The present disclosure relates to an anti-burn RF electrode cartridge for skin care and treatment that keeps the part, where an RF electrode is concentrated, away from the skin during a procedure by positioning the edge end of the RF electrode, and a handpiece for skin care and treatment including the anti-burn RF electrode cartridge.
In general, a handpiece with an RF electrode is a device that treats the skin and the tissues under the skin by heating them using the RF electrode (radio frequency).
Handpieces with an RF electrode are used to restore the skin by increasing the temperature of the skin after cryo fat reduction for obesity treatment and are used for skin treatment that generates contraction of collagen or causes a wound healing response by heating the skin or the tissues under the skin.
Recently, as the interest in skin care increases, handpieces with an RF electrode are used in various ways such as remodeling/resurfacing of the skin by inducing contraction of collagen in the lower derma or a wound healing response, removing of wrinkles, and treatment of sebaceous glands, adipose tissues of hair follicles, and spider veins.
A handpiece with an RF electrode includes an RF electrode cartridge including an RF electrode assembly to come in contact with the skin of a patient, and a handpiece body casing to which the RF electrode cartridge is separably coupled and that is connected to a control body.
Handpieces with an RF electrode are implemented in various patterns to fit to the types of skin treatment by controlling an electrical signal that is applied to an RF electrode on a surface of an RF electrode cartridge, thereby increasing the effect of corresponding skin treatment.
Accordingly, a relay for controlling an electrical signal that is applied to an RF electrode is disposed at a handpiece body casing.
An RF electrode cartridge is an expendable of which the number of times is set in advance, and is replaced when the preset available number of times is reached.
Further, since the relay disposed at a handpiece body casing is also an expendable of which the number of times is set in advance, when a handpiece body casing is also replaced when the number of times of the relay is reached.
Meanwhile,
That is, referring to
The RF electrode 1 has a characteristic that when an RF signal is applied, RF energy concentrates to the edge of the RF electrode, that is, the outer periphery of the RF electrode 1.
Accordingly, when an RF signal is generated through the RF electrode 1 with the tip 2 of the RF electrode cartridge for skin care and treatment in contact with the skin, the patient may get burned by the RF energy concentrating to the edge of the RF electrode, that is, the outer periphery of the RF electrode 1 during a procedure.
In particular, when the RF electrode 1 is in contact with the skin during a procedure, the edge of the RF electrode 1, that is, the part where the RF energy concentrates is spaced apart from the skin due to a curved surface of the skin, that is, the elasticity of the skin in many cases, and, in this case, there is a problem that the patient gets burned due to a spark.

It is exemplified that the RF electrode assembly 120 is integrally formed by plating on the bottom and the outer surface of the tip part 101.
It is exemplified that the contact electrode part 121 covering the entire bottom of the tip part 101 and the side electrode part 122 connected to the contact electrode part 121 and surrounding the outer surface of the tip part 101 are plating layers integrally formed by plating.
The RF electrode assembly 120 is formed as a plating layer, so it covers the entire bottom of the tip part 101 and can be easily formed in a shape surrounding the outer surface.
The end of the RF electrode assembly 120, that is, the edge of the RF electrode assembly 120, at which RF energy concentrates during a procedure in which the RF electrode assembly 120 generates an RF signal, faces up on the side of the tip part 101, so it is possible to prevent an accident that a patient gets burned due to the RF energy concentrating at the edge of the RF electrode assembly 120, that is, the outer periphery of the RF electrode assembly 120 during a procedure while generating an RF signal through the RF electrode assembly 120.
That is, the contact electrode part 121 of the RF electrode assembly 120 that is in contact with the skin during a procedure covers the entire bottom of the tip part 101 and the end of the RF electrode assembly 120, to which an RF signal is applied, is positioned to face up on the outer surface of the tip part 101, is spaced apart from the skin of a patient, and is not contact with the skin of the patient by the side electrode part 122 integrally formed with the contact electrode part 121 to surround the outer surface of the tip part 101, whereby it is possible to completely prevent an accident that the patient gets burned due to a spark that is generated when the contact with the skin is removed.
Meanwhile, the RF electrode assembly 120 further includes an insulating film member 123 that covers the entire surface of the contact electrode part 121 and covers at least a portion of the side contact part 122.
The insulating film member 123 prevents the RF electrode assembly 120 from directly coming in contact with the skin of a patient by covering the surface of the contact electrode part 121 supposed to come in contact with the skin.
The RF electrode assembly 120 is connected to an RF signal application wire part 101a for applying AC power on the outer surface of the tip part 101, that is, on the side electrode part 122.
The RF electrode assembly 120 receives AC power through the RF signal application wire part 101a connected to the side electrode part 122, thereby stably generating an RF signal to the surface of the contact electrode part 121 supposed to come in contact with the skin.

That is, when a practitioner holds the handpiece body casing 200 and presses the handpiece body casing 200 with the RF electrode assembly 120 in contact with the skin, the RF electrode cartridge 100 is pushed and presses and moves the cartridge coupling block 210 while moving to the handpiece body casing 200, and accordingly, the switch-mounting protrusion 116 presses the switch button 115a, whereby electrical power is applied to the RF electrode assembly 120.
Further, when the handpiece body casing 200 is not pressed, that is, a practitioner does not presses the handpiece body casing 200 with the RF electrode assembly 120 in contact with the skin, the cartridge coupling block 210 is moved to the initial position by the spring member 220 for a cartridge and the switch button 115a is also returned to the initial position by the elastic restoring force of the switch spring 115b, so electrical power supplied to the RF electrode assembly 120 is cut, whereby the operation of the RF electrode assembly 120 is stopped.
According to the handpiece for skin care and treatment of the present disclosure, electrical power is applied to the RF electrode assembly 120 only when a practitioner holds and presses the handpiece body casing 200 during a procedure, and when the practitioner removes the force pressing the handpiece body casing 200, electrical power supplied to the RF electrode assembly 120 is automatically cut by the elastic restoring force of a spring, whereby it is possible to accurately perform a procedure on a necessary part an accurate number of times and it is also possible to prevent accidents such as injury to the skin due to excessive stimulation during treatment.
The anti-burn RF electrode cartridge 100 for skin care and treatment according to the present disclosure and the handpiece for skin care and treatment including the anti-burn RF electrode cartridge perform a procedure while moving the RF electrode assembly 120 in close contact with the skin of a patient.
In this case, the tip part 101 of the RF electrode cartridge 100 freely tilts within 360 degrees around the ball joint part 140 such that the RF electrode assembly 120, that is, the contact electrode part 121 can keep in close contact with the skin.
Further, vibration by the vibration motor part further improves the treatment effect of a procedure by generating a massage effect on the skin.
Further, the spring member 220 for a cartridge elastically attenuates the pressing force that is applied by a practitioner and the elastic restoring force of the spring member 220 for a cartridge can further keep the RF electrode assembly 120 in close contact with the skin.
Since the edge end of the RF electrode assembly that is the part where RF energy concentrates during a procedure is positioned to face up on the outer surface of the tip part 101 such that the part where RF energy concentrates during a procedure is spaced apart from the skin, the present disclosure prevents an accident of generation of a spark between the edge end of the RF electrode and the skin during a procedure, thereby having an effect of preventing a patient from getting a burn on the skin during skin treatment that uses an RF signal and greatly improving safety during a procedure.
Since the RF electrode assembly 120 moves in close contact with the skin while freely tilting within 360 degrees around the ball joint part 140 during a procedure, an accident such as injury to skin tissues or a burn on the skin when the RF electrode assembly 120 is separated from the skin is prevented, thereby greatly improving safety during a procedure.
The present disclosure is not limited to the embodiments described above and may be modified in various ways without departing from the scope of the present disclosure and the modifications should be construed as being included in the present disclosure.
