Description

High-frequency treatment device that detects changes in the treatment area

[0001] The present invention relates to a high-frequency treatment device that detects changes in a treatment area.

[0002]

[0003] Recently, technologies for treating skin by modifying the tissue condition or improving tissue characteristics by providing energy to the skin using various energy sources have been widely applied.

[0004] Among these, in the case of a skin treatment device using RF high frequency, high frequency energy is provided to the skin surface, and whenever the direction of the high frequency current changes, molecules constituting the skin tissue vibrate and rub against each other, and the temperature of the skin tissue is increased through deep heat generated by rotational motion, twisting, or collisional motion, thereby reorganizing the collagen layer, thereby improving wrinkles and changing skin elasticity. This RF high frequency skin treatment technology has been disclosed in Korean Patent Publication No. 10-1451960 (application date: May 9, 2013, announcement date: November 3, 2014, hereinafter referred to as “prior art”).

[0005] This skin treatment technology using RF high frequency utilizes the principle of generating high temperature heat at the same point, so if multiple high frequency waves are outputted continuously to the same treatment area, the subject of the treatment may complain of a burning sensation, and in severe cases, burns may occur on the skin area. However, in the case of the conventional technology, there was no means to prevent multiple high frequency outputs from being provided to the same treatment area, so there was a problem in that it was difficult to prevent treatment accidents.

[0006]

[0007] The present invention aims to solve the above-described problem by providing a treatment area change detection type high-frequency treatment device that prevents the continuous provision of multiple high-frequency outputs to the same treatment area.

[0008]

[0009] A high-frequency treatment device for detecting a change in a treatment area according to one embodiment of the present invention comprises: a main body for controlling the supply of an electric signal; a handpiece including a stick-shaped body part electrically connected to the main body and at least two displacement measuring parts for detecting displacement of the body part; and a cartridge detachably coupled to the handpiece and for outputting a high frequency through an electric signal supplied from the main body through the handpiece; wherein the main body is characterized in that it controls the supply of an electric signal for generating a high frequency signal to the cartridge through the handpiece only when it is determined that a change in the treatment area has occurred from a previous high frequency-provided treatment area through the cartridge, based on a result of measuring the displacement of the body part through the at least two displacement-measuring information.

[0010] Here, the handpiece is characterized by including a body part that is provided in a stick shape to which the cartridge is coupled at one end, and is electrically connected to the main body through a cable to transmit an electric signal supplied from the main body to the cartridge coupled at one end; a first displacement measuring part that is located inside adjacent to one end of the body part and measures the occurrence of movement of one end of the body part; and a second displacement measuring part that is located inside adjacent to the other end of the body part and measures the occurrence of movement of the other end of the body part.

[0011] In addition, the main body is characterized by including a signal generating unit that generates an electric signal for high-frequency output of a cartridge coupled to the handpiece, and a control unit that controls the supply of the electric signal generated from the signal generating unit to the handpiece according to the measurement results of the first and second displacement measuring units.

[0012] And, the control unit is characterized in that, after providing high frequency to an arbitrary treatment area by supplying an electric signal generated from the signal generating unit to the cartridge coupled to the handpiece, only when it is determined through the displacement measurement results of the first and second displacement measuring units that the cartridge has left the treatment area, the control unit additionally supplies an electric signal generated from the signal generating unit to the cartridge coupled to the handpiece.

[0013] In addition, the first and second displacement measuring units are each characterized by being provided with one of an acceleration sensor and an angular velocity sensor or a combination of the two.

[0014]

[0015] The high-frequency treatment device for detecting a change in the treatment area according to the present invention has an effect of preventing the occurrence of treatment accidents by preventing high frequencies from being outputted continuously multiple times in the same treatment environment by controlling the high-frequency output of the cartridge coupled to the handpiece only when the treatment area has changed through the control unit of the main body checking whether the treatment area has changed through the displacement measurement result of the handpiece during the treatment process.

[0016] In addition, the high-frequency treatment device for detecting a change in the treatment area according to the present invention has first and second displacement measuring units positioned at both ends of the handpiece in the longitudinal direction, so that the control unit can determine, through the measurement results of the first and second displacement measuring units, whether a movement that can change the treatment area has occurred in the handpiece or whether a simple tilt has occurred without changing the treatment area, thereby enabling accurate detection of a change in the treatment area.

[0025]

[0026] FIG. 1 illustrates a treatment area change detection type high-frequency treatment device according to a preferred embodiment of the present invention, FIG. 2 partially illustrates a handpiece of a treatment area change detection type high-frequency treatment device according to a preferred embodiment of the present invention, and FIG. 3 is a diagram illustrating an example of treatment area change of a handpiece of a treatment area change detection type high-frequency treatment device according to a preferred embodiment of the present invention.

[0027] Referring to FIG. 1, a high-frequency treatment device (10) capable of detecting a change in treatment area according to a preferred embodiment of the present invention may include a main body (100), a handpiece (200), and a cartridge (300).

[0028] The main body (100) is electrically connected to the handpiece (200) to be described later via a cable, and can control the supply of an electric signal for high-frequency output of a cartridge (300) coupled to the handpiece (200), and may include a signal generation unit (110) that generates an electric signal for high-frequency output, and a control unit (120) that controls the supply of the electric signal of the signal generation unit (110). Here, the control unit (120) controls the signal generation unit (110) only when it is confirmed that a treatment area has been changed according to the purpose of the present invention, and supplies an electric signal for high-frequency output of the cartridge (300) coupled to the handpiece (200). This confirmation of the change in the treatment area by the control unit (120) is made through a displacement measurement result provided from the handpiece (200) to be described later.

[0029] Referring to FIG. 2, the handpiece (200) may include a stick-shaped body part (210) electrically connected to the main body (100), and first and second displacement measuring parts (220, 230) for detecting displacement of the body part. The body part (210) is provided in a stick shape with a cartridge (300) coupled to one end, and is electrically connected to the main body (100) via a cable so as to transmit an electric signal supplied from the main body (100) to the cartridge (300) coupled to one end. The first displacement measuring part (220) is located inside adjacent to one end of the body part (210), and can measure the occurrence of movement of one end of the body part (210). The second displacement measuring part (230) is located inside adjacent to the other end of the body part (210), and can measure the occurrence of movement of the other end of the body part (210). Here, both the first and second displacement measuring units (220, 230) may be provided as acceleration sensors or angular velocity sensors, or one may be provided as an acceleration sensor and the other as an angular velocity sensor. However, it is preferable that the first displacement measuring unit (230) disposed at one end of the handpiece (200) where the amount of angular change compared to the movement distance caused by the movement of the cartridge (300) that comes into contact with the treatment area is provided as an acceleration sensor, and the second displacement measuring unit (230) disposed at the other end of the handpiece (200) where the amount of angular change compared to the movement distance caused by the movement is large is provided as an angular velocity sensor.

[0030] Referring to FIGS. 2 and 3, in the case of a stick-shaped handpiece (200) having a cartridge (300) generally coupled to one end, when a practitioner, while holding the handpiece (200), brings the cartridge (300) into contact with a specific treatment area (t1) and then attempts to move it to another treatment area (t2), a certain level of movement occurs at both the one end and the other end to which the cartridge (300) is coupled, and in some cases, rotation may also occur. Accordingly, the first and second displacement measuring units (220, 230) measure the displacement occurrence at one end and the other end of the handpiece (200), respectively, and the displacement measurement results through the first and second displacement measuring units (220, 230) are provided to the control unit (120) of the main body (100), so that the control unit (120) checks whether a change in the actual treatment area has occurred according to the measurement results of each of the first and second displacement measuring units (220, 230). In addition, the handpiece (200) may further include an operation unit (240) that generates a request signal requesting a high-frequency output to the control unit (120) of the main body (100), and when the operator positions the cartridge (300) so that it touches the treatment area while holding the handpiece (200), high-frequency can be provided to the treatment area by operating the operation unit (240).

[0031] The cartridge (300) may be detachably coupled to the handpiece (200), output high frequency through an electric signal supplied from the main body (100) through the handpiece (200), and may include an output electrode (310) connected to the handpiece (200) and output high frequency through an electric signal supplied from the main body (100). Meanwhile, the cartridge (300) may further include a detection sensor (320) that detects whether there is contact with the treatment site in order to prevent high frequency from being output in a non-contact state with the treatment site. At this time, the detection sensor (320) may be provided as a pressure-sensitive sensor or a capacitive sensor. That is, the cartridge (300) is coupled to the handpiece (200), and outputs high frequency to the output electrode (310) through an electric signal provided from the main body (100) through the handpiece (200), and the detection result of whether the cartridge (300) has come into contact with the treatment area can be provided to the control unit (120) of the main body (100) through the handpiece (200).

[0032] Hereinafter, with reference to the attached drawings, a method for controlling high-frequency output through a control unit (120) of a high-frequency treatment device (10) for detecting a change in treatment area according to a preferred embodiment of the present invention will be described in detail.

[0033]

[0034] Fig. 4 is a diagram illustrating an example of detection of a change in the treatment area of ​​a high-frequency treatment device according to a preferred embodiment of the present invention. Fig. 4 (a) is a diagram illustrating high-frequency output control through a control unit (120) in a state where the treatment area to which the cartridge (300) comes into contact is not changed and the handpiece (200) is simply tilted, and Fig. 4 (b) is a diagram illustrating high-frequency output control through a control unit (120) in a state where the treatment area to which the cartridge (300) comes into contact is changed.

[0035] When a practitioner holding a handpiece (200) requests high-frequency output by manipulating the operating unit (240), the control unit (120) provides an electric signal for high-frequency output generated from the signal generating unit (110) to the output electrode (310) of the cartridge (300) only when it is confirmed that the cartridge (300) has contacted the treatment area through the detection result of the detection sensor (320) of the cartridge (300) without first checking whether the treatment area has changed. After the initial provision of high-frequency output in this way, the displacement measurement results of the first and second displacement measurement units (220, 230) are checked, and it is checked whether the measurement values ​​of the first and second displacement measurement units (220, 230) exceed a preset reference value, i.e., whether a movement greater than a certain level has occurred, and the high-frequency output is controlled by confirming that the cartridge (300) has contacted the treatment area as a result of the detection sensor (320). If, as in (a) of FIG. 4, there is almost no change in the treatment area and the handpiece (200) is simply tilted, the control unit (120) checks whether the cartridge (300) has come into contact with the treatment area through the detection result value (a3) ​​of the first detection sensor (320), and even if the measurement result value (a2) of the second displacement measurement unit (230) exceeds the reference value, it checks that the measurement result value (a1) of the first displacement measurement unit (220) is less than the reference value, and determines that there is almost no change in the area from the previous high-frequency provision area through the output electrode (310) of the cartridge (300), and controls the signal generation unit (110) not to provide an electric signal for high-frequency output to the output electrode (310) of the cartridge (300). At this time, so that the operator can also check the judgment result of the control unit (120), the main body (100) displays 'This is the same area as the previous treatment area. Please change the treatment area.'An output unit (130) including a display that outputs guidance text such as 'etc.' may be additionally configured, and the output unit (130) may be provided in a form in which additional notification means such as sound and lighting are combined. Meanwhile, as in (b) of FIG. 4, if a change in the treatment area has occurred, the control unit (120) checks whether the cartridge (300) has come into contact with the treatment area through the detection result value (a3) ​​of the initial detection sensor (320), and the control unit (120) determines that the measurement result values ​​of the first and second displacement measurement units (220, 230) all exceed the reference value, thereby determining that a change in the treatment area has occurred from the previous high-frequency provision area through the output electrode (310) of the cartridge (300), and controls the signal generation unit (110) so that an electric signal for high-frequency output is provided to the output electrode (310) of the cartridge (300).

[0036]

[0037] That is, the high-frequency treatment device for detecting a change in the treatment area according to the present invention has the effect of preventing the occurrence of treatment accidents by preventing high frequencies from being outputted continuously multiple times in the same treatment environment by controlling the high-frequency output of the cartridge coupled to the handpiece only when the treatment area has changed through the control unit of the main body checking whether the treatment area has changed through the displacement measurement result of the handpiece during the treatment process.

[0038] In addition, the high-frequency treatment device for detecting a change in the treatment area according to the present invention has first and second displacement measuring units positioned at both ends of the handpiece in the longitudinal direction, so that the control unit can determine, through the measurement results of the first and second displacement measuring units, whether a movement that can change the treatment area has occurred in the handpiece or whether a simple tilt has occurred without changing the treatment area, thereby enabling accurate detection of a change in the treatment area.
