In addition, the cartridge coupling block 210 is positioned such that the cartridge coupling block 210 is capable of being moved in the longitudinal direction of the handpiece body casing 200, and a spring member 220 for a cartridge configured to elastically support the cartridge coupling block 210 is positioned in the handpiece body casing 200.
The coolant circulation line part 200a may be a hose which is capable of being freely bent within the handpiece body casing 200 and which has a spare length equal to at least a movement distance of the RF electrode cartridge 100, or may be a hose which has a bellows structure and which is configured such that a length of the hose is capable of being adjusted within the handpiece body casing 200.
The spring member 220 for the cartridge is configured to elastically support the cartridge coupling block 210 to which the RF electrode cartridge 100 is coupled and which is capable of being moved, so that the spring member 220 for the cartridge serves to buffer a load applied to the patient when the RF electrode body 120 is pressed and is brought into close contact with the skin of the patient. Furthermore, the spring member 220 is configured to push the RF electrode cartridge 100 toward the skin of the patient with an elastic resilience force so that the RF electrode body 120 is more fully brought into close contact with the skin of the patient.
A cartridge movement guide part 230 configured to guide a rectilinear movement of the cartridge coupling block 210 is positioned in the handpiece body casing 200.
The cartridge movement guide part 230 may include a movement guide bar part 231 that is positioned such that the movement guide bar part 231 protrudes on the cartridge coupling block 210, and may include a movement guide block 232 which is positioned in the handpiece body casing 200 and through which the movement guide bar part 231 passes and the movement guide bar part 231 is movably coupled to the movement guide block 232.
In addition, as an example, the movement guide bar part 231 includes a plurality of movement guide bar parts 231, and at least one of the plurality of movement guide bar parts 231 is positioned through the spring member 220 for the cartridge, the spring member 220 being a coil spring.
That is, as an example, the spring member 220 for the cartridge is the coil spring, and the movement guide bar part 231 is positioned by penetrating the spring member 220 for the cartridge such that a first end portion of the movement guide bar part 231 is supported on the cartridge insertion part 200b and a second end portion of the movement guide bar part 231 is supported on the movement guide block 232, so that the spring member 220 for the cartridge elastically supports the rectilinear movements of the cartridge coupling block 210 and the RF electrode cartridge 100 coupled to the cartridge coupling block 210.
Meanwhile, in the RF electrode cartridge 100 including the relay for skin cosmetic treatment according to the present disclosure, an electrode on/off switch 115 configured to turn on/off electric power applied to the RF electrode body 120 is positioned on the upper surface of the cartridge casing 110. That is, the electrode on/off switch 115 is positioned on the upper surface of the second casing part 200b.
The electrode on/off switch 115 includes a switch button 115a elastically supported by a switch spring 115b, and has a structure in which electric power applied to the RF electrode body 120 is turned on only when the switch button 115a is pressed and pushed and the electric power is turned off when the switch button 115a is released from a pressed state.
In addition, in the inner portion of the handpiece body casing 200, which is the inner portion of the cartridge insertion part 200b, a protrusion part 241 for pressing a switch configured to press and push the electrode on/off switch 115 when the cartridge coupling block 210 is pushed and moved is positioned such that the protrusion part 241 for pressing the switch protrudes.
The protrusion part 241 for pressing the switch is positioned such that the protrusion part 241 for pressing the switch is in contact with an 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, which is the upper surface of the second casing part 200b, a switch mounting protrusion part 116 having an upper surface on which the electrode on/off switch is positioned is positioned such that the switch mounting protrusion part 116 protrudes. Furthermore, a protrusion insertion part 240 into which the switch mounting protrusion part 116 is inserted is positioned inside the cartridge insertion part 200b, and the protrusion part 241 for pressing the switch protrudes and is positioned in the protrusion insertion part 240 such that the protrusion part 241 for pressing the switch faces the switch mounting protrusion part 116.
The electrode on/off switch 115 is positioned such that the upper surface of the switch button 115a protrudes toward an upper surface of the switch mounting protrusion part 116 or the upper surface of the switch button 115a is in a plane with the upper surface of the switch mounting protrusion part 116. When the RF electrode cartridge 100 is coupled to the handpiece body casing 200, the switch mounting protrusion part 116 is inserted inside the protrusion insertion part 240, and the protrusion part 241 for pressing the switch is positioned such that the protrusion part 241 for pressing is in contact with the upper surface of the switch button 115a.
That is, in a state in which the operator holds the handpiece body casing 200 and the RF electrode body 120 is brought into close contact with the skin, when the operator pushes the handpiece body casing 200, the RF electrode cartridge 100 is pushed and is moved toward the handpiece body casing 200, and the cartridge coupling block 210 is pushed and moved, so that the switch mounting protrusion part 116 pushes the switch button 115a, thereby applying electric power to the RF electrode body 120.
In addition, in a state in which the RF electrode body 120 is brought into contact with the skin, when the handpiece body casing 200 is not pushed, which is when the operator does not push the handpiece body casing 200, the cartridge coupling block 210 is moved to the original position by the spring member 220 for the cartridge, and the switch button 115a is also returned to the original position by the elastic resilience force of the switch spring 115b, so that electric power applied to the RF electrode body 120 is blocked and the operation of the RF electrode body 120 is turned off.
In the handpiece for skin cosmetic treatment according to the present disclosure, electric power is applied to the RF electrode body 120 only when the operator holds and pushes the handpiece body casing 200 during the procedure. Furthermore, when the operator releases the force pushing the handpiece body casing 200 during the procedure, the electric power applied to the RF electrode body 120 is automatically blocked due to the elastic resilience force of the spring. Therefore, the procedure is capable of being accurately performed in the required area and the exact number of uses, and an accident such as skin damage due to excessive stimulation during the treatment is also capable of being prevented.
In the RF electrode cartridge 100 including the relay for skin cosmetic treatment according to the present disclosure and the handpiece including the RF electrode cartridge 100 for skin cosmetic treatment, the procedure is performed by moving the RF electrode body 120 while the RF electrode body 120 is brought into close contact with the skin of the patient.
At this time, the first casing part 110a of the RF electrode cartridge 100 is configured to be tilted freely at the 360-degree radius around the ball joint part 140, so that the RF the state in which the RF electrode body 120 is continuously in close contact with the skin may be maintained.
In addition, the massaging effect is generated on the skin by vibration caused by the vibration motor unit, thereby further inducing a treatment effect according to the procedure.
In addition, the pressing force caused by the operator is buffered by the elastic supporting of the spring member 220 for the cartridge, and the state in which the RF electrode part 120 is brought into close contact with the skin may be more reliably maintained due to the elastic resilience force of the spring member 220 for the cartridge.
In the present disclosure, during the procedure, since the RF electrode body 120 is tilted freely at the 360-degree radius around the ball joint part 140 and is moved while being brought into close contact with the skin, an accident in which the RF electrode body 120 is separated from the skin and a damage to the skin tissue or a burn to the skin occurs is prevented from occurring, so that safety during the procedure may be significantly increased.
In the present disclosure, the relay 190 that controls the electrical signal applied to the RF electrode is positioned in the RF electrode cartridge, so that the relay 190 that is the consumable part is replaced when the RF electrode cartridge is replaced. Therefore, the handpiece body casing 200 is capable of being used without being replaced, so that the hassle and the cost of replacing the handpiece body casing 200 may be reduced.
In the present disclosure, since the vibration motor unit is provided, the pain that occurs during the skin treatment may be minimized, and the treatment effect may be increased.
In the present disclosure, since electric power is applied to the RF electrode body 120 only when the RF electrode cartridge that is brought into contact with the skin is pressed, a safe and convenient treatment is capable of being realized, and safety during the treatment may be increased.
It is to be understood that the present disclosure is not limited to the above described embodiments but may be variously modified and embodied within the scope of the present disclosure without departing from the gist of the present disclosure.
