The above and other objectives, features, and other advantages of the present disclosure will be more clearly understood from the following detailed description when taken in conjunction with the accompanying drawings. However, the disclosure may be embodied in different forms without being limited to the embodiments set forth herein.

Hereinafter, the term “RF treatment device” covers all devices for treating humans as well as animals such as mammals. The treatment device may include various devices that transmit RF energy for the purpose of improving the condition of a lesion or tissue. Although a device for treating a skin lesion will be mainly described in the following embodiment, the present disclosure is not limited thereto. That is, it is to be understood that the treatment device may be applied to various devices that transmit RF energy to various affected areas, including a device for surgically treating internal organ lesions.

Hereinafter, the term “treatment” refers to remodeling in which RF energy is transmitted to tissue including collagen to change the state of the tissue into at least one of coagulation or ablation, and may be treatment for at least one of wrinkles, tone and textural changes, scars and acne scarring, sagging mucosa, overall rejuvenation, hyperhidrosis, laxity, lifting, tightening, and fat reduction for skin tissue, for example.
Hereinafter, an RF treatment device and a control method of the RF treatment device according to an embodiment of the present disclosure will be described with reference to the drawings.
As shown in
An RF generator 111 (see
A switch 101 for adjusting the operation of the treatment device, e.g., the operation of turning on or off a power supply, and a display unit 102 for displaying various pieces of information including the operation of the treatment device may be included on the outer surface of the body 100. Such a display unit 102 may be formed of a touch screen to display various pieces of information, and may be configured such that a user may directly set treatment contents through the display unit 102.
The handpiece 200 is connected to the body via a connector 300. The connector 300 may transmit power or a control signal required to operate various devices of the handpiece 200 from the body 100. Furthermore, the connector 300 may transmit the RF energy from the RF generator 111 to the handpiece 200. To this end, the connector 300 may be formed of a cable including various signal lines and power lines, or may have a bent structure to be easily bent by a user's manipulation.
As shown in
A handpiece operating part 230 and a handpiece display part 220 may be provided on an outer surface of the body part 210. The handpiece operating part 230 may be configured to control the on/off of the handpiece 200 or the intensity of the RF energy transmitted through the needle 250. The display unit 220 of the handpiece may display various pieces of information required in a setting mode or during treatment to a user. Thus, a user may perform treatment by operating the operating part 230 with the handpiece 200 being held by his or her hand, and simultaneously check treatment contents easily through the display unit 220.
The above-described connector 300 is connected to a rear end of the body part 210, and the rolling member 240 is coupled to a front end of the body part 210. To this end, as shown in
The first support arm 211 rotatably supports one side of the rolling member 240, while the second support arm 212 rotatably supports the other side of the rolling member 240. The first support arm 211 and the second support arm 212 support a horizontal central axis (not shown) of the rolling member 240 to allow the rolling member 240 to be stably rotated.
A signal line and a power line electrically connected to the rolling member 240 may be provided in the first support arm 211 and/or the second support arm 212 so that the RF energy transmitted through the connector 300 and the body 100 may be transmitted to the rolling member 240 through at least one of the first support arm 211 and the second support arm 212, and information collected from the rolling member 240 is transmitted through at least one of the first support arm 211 and the second support arm 212 to the body 100.
At least one of the first support arm 211 and the second support arm 212 includes a coupling element 212a.
The coupling element 212a serves to maintain electrical connection with the signal line and the power line of the first support arm 211 and/or second support arm 212 even when the rolling member 240 is rotating. To this end, the coupling element 212a may include a brush element that maintains the electrical connection of a stationary part and a movable part.
As shown in
The plurality of needles 250 may extend radially from the horizontal central axis of the rolling member 240. The plurality of needles 250 may be formed of a conductive material to receive and release the RF energy transmitted through the rolling member 240. A part of a surface of each needle excluding its front end may be formed of an insulating material to prevent the RF energy from being transmitted to the tissue. Thereby, each needle is configured such that a part of the front end thereof serves as an electrode, and the RF energy is transmitted to the tissue only through the front end. Thus, it is possible to selectively transmit the RF energy to a part at which the end of the needle is located during treatment.
The rolling member 240 may be configured such that the plurality of needles 250 is divided into a plurality of needle groups, and RF energy is independently transmitted to each needle group. Each needle group may include a few or tens of needles 250. According to an embodiment, at least some of the needle groups may include one needle 250. According to an embodiment, the needle groups may be divided on the basis of a row that is perpendicular to the forward and/or backward movement direction of the rolling member 240.
To this end, the rolling member 240 may include an electric circuit in which the plurality of needles 250 is divided into the plurality of needle groups and is electrically connected in a matrix form. The electric circuit is electrically connected to the coupling element 212a of the first support arm 211 and/or the second support arm 212 to receive the RF energy transmitted through the first support arm 211 and/or the second support arm 212 to the rolling member 240 and thereby transmit the RF energy to at least some of the plurality of needles 250.
Preferably, the rolling member 240 is manufactured to be separable from the body part 210. In this case, the rolling member 240 is configured to be disposable, so that the rolling member is separated from the body part 210 and then is discarded after the RF treatment is performed for one patient. When the RF treatment is performed on another patient, a new rolling member 240 may be coupled to the body part 210.
As shown in
As the rolling member 240 rotates while coming into close contact with the surface of the skin D, the needle 250 is sequentially inserted into the skin D and then is removed from the skin D. This process is repeated.
The RF energy is released from the front end of the needle 250 inserted into the skin D, and the RF energy is transmitted to the interior of the tissue at a treatment location Z, so that treatment is performed. Since a location where the needle 250 is inserted varies as the rolling member 240 moves forwards or backwards, the treatment location Z is correspondingly moved.
Although
As shown in
The skin impedance measurement unit 400 is configured to monitor the state information of the tissue corresponding to the treatment location Z during treatment.
The skin impedance measurement unit 400 may be provided on a path to which the RF energy is transmitted, and may be configured to measure the impedance of the path to which the RF energy is transmitted after passing through the tissue. The skin impedance measurement unit 400 may be provided on an RF transfer path in the handpiece 200, and may be provided on an RF transfer path in the body.
The skin impedance measurement unit 400 may monitor an impedance value by causing a separate test current to flow through the plurality of needles 250, and may monitor an impedance value measured while the RF energy is transmitted. Since the measured impedance varies depending on the characteristics of a patient or a change in skin condition, this impedance may be interpreted as ‘skin impedance’ for convenience.
The information measured by the skin impedance measurement unit 400 is information related to the skin impedance. This may be an impedance value of the treatment location Z in the needle 250 is inserted, and may be information for inferring the impedance of the treatment location Z.
Meanwhile, since the information measured by the skin impedance measurement unit 400 is acquired through the needle 250 inserted into the skin, it is possible to confirm the needle 250 inserted into the skin among the plurality of needles 250 on the basis of the measured information. The rolling member 240 may be controlled to receive information about the needle 250 inserted into the skin from the skin impedance measurement unit 400 and to transmit the RF energy to only the needle 250 inserted into the skin. When the plurality of needles 250 is divided into the plurality of needle groups, control may be performed such that the RF energy is transmitted to only the needle group including the needle 250 inserted into the skin.
Thereby, since the RF energy is transmitted to only the needle 250 inserted into the skin D and the RF energy is not transmitted to the needle 250 that is not inserted into the skin D but is exposed, it is possible to prevent a user or a patient from getting unexpected electric shocks caused by the needle 250 that is not inserted into the skin D but is exposed, during treatment.
The speed measurement unit 500 is configured to monitor information related to the moving speed of the handpiece 200 and/or the rolling member 240.
The speed measurement unit 500 may be configured to detect the moving speed of the handpiece 200, or to detect the rotating speed or the moving speed of the rolling member 240. For example, the speed measurement unit 500 may include an acceleration sensor provided in the body part 210 of the handpiece 200 to detect the moving speed of the handpiece 200. Alternatively, an encoder, a tachometer for measuring RPM in an optical manner or a Keyphasor may be provided in the front end of the body part 210 of the handpiece 200 to detect the rotating speed of the rolling member 240. They are merely examples of the speed measurement unit 500, and the present disclosure is not limited thereto. Various configurations capable of detecting the moving speed of the handpiece 200 or detecting the rotating speed or the moving speed of the rolling member 240 may be used as the speed measurement unit 500.
Information measured by the speed measurement unit 500 may be information related to speed (the moving speed of the handpiece 200, the rotating speed of the rolling member 240, and the moving speed of the rolling member 240). This may be a speed value, and may be information for inferring speed.
The RF control unit 300 receives information related to the skin impedance from the skin impedance measurement unit 400, and receives information related to the speed from the speed measurement unit 500. Further, the RF control unit may control the RF generator 111 on the basis of information transmitted from the skin impedance measurement unit 400 and the speed measurement unit 500 to adjust the on/off operation of the RF pulse and the parameter of the RF pulse.
The RF control unit 300 controls the RF generator 111 on the basis of information transmitted from the skin impedance measurement unit 400. Since the skin impedance varies depending on a patient or a body region and a change occurs in skin tissue of the treatment location Z during the RF treatment, the skin impedance is also changed during the RF treatment. Even if the same RF energy is applied, a therapeutic effect realized in the tissue of the treatment location Z varies depending on the impedance of the treatment location Z.
Thus, for optimal RF treatment, RF energy optimized for the impedance of the treatment location Z should be applied. Since the RF control unit 300 receives the information, related to the impedance of the treatment location Z into which the needle 250 is inserted, in real time and controls the output of the RF energy in response to the received information, it is possible to achieve the optimal RF treatment for the treatment location Z.
The RF control unit 300 controls the RF generator 111 on the basis of the information related to the speed from the speed measurement unit 500.
In order to provide appropriate therapeutic effect for the treatment location Z, the RF energy that is equal to or more than a predetermined level should be applied to the tissue of the treatment location Z. However, due to a difference in speed at which the handpiece 200 is operated (the rolling member 240 slides on a skin surface) depending on a user, the handpiece 200 may be operated at a speed that is higher or lower than an expected speed in a step of manufacturing the RF treatment device 1. In this case, sufficient therapeutic effect may not be realized, or RF energy more than necessary may be applied to the treatment location Z, thus possibly causing side effects such as burns.
To this end, the RF control unit 300 may receive the information related to the speed from the speed measurement unit 500, may control the RF generator 111 to increase the output of the RF energy when the received information corresponds to a state in which the speed of the handpiece 200 and/or the rolling member 240 is higher than a reference speed (a preset value), and may control the RF generator 111 to decrease the output of the RF energy when the received information corresponds to a state in which the speed of the handpiece 200 and/or the rolling member 240 is lower than the reference speed.
The RF control unit 300 may control the RF generator 111 so that the increased amount/decreased amount of the output of the RF energy is proportional to a difference between the speed of the handpiece 200 and/or the rolling member 240 and the reference speed.
Thereby, even if a user performs the treatment while rotating the rolling member 240 at a speed higher than that expected by a manufacturer of the RF treatment device 1, sufficient RF energy may be applied to the treatment location Z because the RF control unit 300 increases the output of the RF energy. In contrast, even if a user performs the treatment while rotating the rolling member 240 at a speed lower than that expected by a manufacturer of the RF treatment device 1, excessive RF energy may be prevented from being applied to the treatment location Z because the RF control unit 300 decreases the output of the RF energy.
Although the RF control unit 300 may be provided on the body 100, it may be provided on the handpiece 200 according to an embodiment.
The RF treatment device 1 according to an embodiment of the present disclosure may further include a monitoring unit that monitors the temperature of tissue or monitors at least one of various pieces of information required for treatment, such as the contact of the handpiece or the pressed state. In this case, the RF control unit 300 may receive information monitored from the monitoring unit and may control the RF control unit 300 on the basis of the received information, thus controlling the output of the RF energy.
According to an embodiment, the monitoring unit may include the skin impedance measurement unit 400.
Furthermore, the RF treatment device 1 according to an embodiment of the present disclosure may further include a setting unit that allows a user to set treatment contents. The setting unit may be composed of the above-described display unit 102 and/or a switch, and may perform a setting operation in a manner of displaying various options to a user through the display unit 102 and selecting a displayed option by the user.
Furthermore, the RF treatment device 1 according to an embodiment of the present disclosure may further include a memory unit in which various data is stored, and may perform a control operation by storing information required for controlling the RF treatment device in the memory unit or reading data stored in the memory unit.
Hereinafter, a method of controlling the RF treatment device according to an embodiment of the present disclosure will be described.
As shown in
In the needle inserting step S11, a user holds the handpiece 200, puts the rolling member 240 on a skin surface of a patient's treatment site to come into close contact therewith, and then inserts some of the plurality of needles 250 into the skin D. As soon as the initial needle 250 is inserted into the skin D, the handpiece 200 may be moved to cause the rolling member 240 to slide on the skin surface.
In the RF-energy transmitting step S11, the RF generator 111 generates the RF energy, and the body 100 transmits the generated RF energy through the connector 300 to the handpiece 200. The RF energy transmitted to the handpiece 200 is transmitted through the first support arm 211 and/or the second support arm 212 to the rolling member 240, and the rolling member 240 transmits the RF energy to at least some of the plurality of needles 250.
When the RF energy is first transmitted to the rolling member 240, the rolling member 240 may transmit the RF energy to all of the plurality of needles 250. This may be intended to identify the location of the needle 250 inserted into the skin and to measure the skin impedance. In this case, the needle inserting step S11 may be performed subsequent to the RF-energy transmitting step S12.
In the case of measuring the skin impedance using the RF energy, the RF-energy transmitting step S12 should precede the skin-impedance measuring step S13 that will be described later. However, when the skin impedance measurement unit 400 monitors the impedance value by causing a separate test current to flow through the plurality of needles 250, the RF-energy transmitting step S12 may be performed subsequent to the RF-energy controlling step S15 that will be described later.
In the skin-impedance measuring step S13, the skin impedance measurement unit 400 acquires information related to the impedance of the treatment location Z into which the needle 250 is inserted. Further, the needle 250 inserted into the treatment location Z may be sensed on the basis of several pieces of impedance information measured from the plurality of needles 250.
In the speed-measuring step S14, the speed measurement unit 500 acquires information related to the speed (the moving speed of the handpiece 200, the rotating speed of the rolling member 240, and the moving speed of the rolling member 240).
In the RF-energy controlling step S15, the RF control unit 300 receives information related to the skin impedance from the skin impedance measurement unit 400, and receives information related to the speed from the speed measurement unit 500 to control the RF generator 111 on the basis of the received information, thus adjusting the on/off operation of the RF pulse and the parameter of the RF pulse.
The RF control unit 300 may be configured to receive information from each of the skin impedance measurement unit 400 and the speed measurement unit 500 in real time and thereby control the RF generator 111.
Since specific examples of the configuration where the RF control unit 300 controls the RF generator 111 on the basis of information transmitted from each of the skin impedance measurement unit 400 and the speed measurement unit 500 have been described above, a detailed description thereof will be omitted herein.
The RF generator 111 may generate the RF energy by the configuration controlled in the RF-energy controlling step S15, and the RF-energy transmitting step S12 may be performed again. That is, the RF control unit 300 feedback controls the RF generator 111 in response to the information transmitted from the skin impedance measurement unit 400 and the speed measurement unit 500 in real time, thus allowing the RF energy optimal for treatment to be transmitted to the tissue of the treatment location Z, in response to a change in skin impedance and a change in speed of the handpiece 200 and/or the rolling member 240.
In the rolling-member controlling step S16, the rolling member 240 is controlled to transmit the RF energy to only the needle 250 inserted into the skin, which is identified in the skin-impedance measuring step S13. In the case of including the electric circuit in which the plurality of needles 250 is electrically connected in a matrix form in the rolling member 240, the electric circuit is controlled to transmit the RF energy to only the needle 250 inserted into the skin. In the case of including the electric circuit in which the plurality of needles 250 is divided into a plurality of needle groups and then is electrically connected, the electric circuit is controlled to transmit the RF energy to only a needle group including the needles 250 inserted into the skin.
Thereby, since the RF energy is transmitted to only the needle 250 inserted into the skin D and the RF energy is not transmitted to the needle 250 that is not inserted into the skin D but is exposed, it is possible to prevent a user or a patient from getting unexpected electric shocks caused by the needle 250 that is not inserted into the skin D but is exposed, during treatment.
As a user moves the handpiece 200 forwards or backwards, the needle 250 inserted into the skin D of the patient is changed, and simultaneously the treatment location Z is also changed. Thus, steps S12 to S16 are repeatedly performed to cause the RF energy suitable for the treatment location Z to be transmitted.
As described above, since the RF treatment device 1 and the control method of the RF treatment device according to an embodiment of the present disclosure control the RF energy in response to the speed of the handpiece 200 and/or the rolling member 240, the appropriate RF energy is applied to the tissue of the treatment location Z even if the speed of moving the handpiece 200 varies depending on a user.
Furthermore, in the RF treatment device 1 and the control method of the RF treatment device according to an embodiment of the present disclosure, the RF energy is transmitted to only the needle 250 inserted into the skin D and the RF energy is not transmitted to the needle 250 that is not inserted into the skin D but is exposed, so that it is possible to prevent a user or a patient from getting unexpected electric shocks caused by the needle 250 that is not inserted into the skin D but is exposed, during treatment.
Hereinbefore, the description has been focused on the treatment device that transmits the RF energy to the skin tissue to perform treatment. However, this is merely illustrative, but may be applied to a treatment device for treating tissues other than the skin tissue. Furthermore, the present disclosure may be applied to various treatment devices of performing treatment by transmitting energy such as RF, laser, or ultrasonic waves, as well as the treatment device of performing treatment by transmitting RF energy, and may be applied to various treatment devices of performing treatment by transmitting a therapeutic substance (e.g. medication, anesthetics, stem cells, etc.).
Although the description has focused on the treatment device composed of the body and the handpiece, the present disclosure may be applied to a treatment device formed of a single handpiece module without being limited thereto.
It is evident to those skilled in the art that the present disclosure may be materialized in other specific forms without departing from the essential characteristics of the present disclosure. Accordingly, the detailed description should not be construed as being limitative from all aspects, but should be construed as being illustrative. The scope of the present disclosure should be determined by reasonable analysis of the attached claims, and all changes within the equivalent range of the present disclosure are included in the scope of the present disclosure.
