High Frequency Therapy Sytem with Safety Function and Operating Method

The present invention relates to a radiofrequency treatment system having a safety function and a method of operating the same. More particularly, the present invention relates to a function of suppressing unnecessary pain of a patient due to a radiation error of a radiofrequency voltage and reducing burden on a medical practitioner. It relates to a radiofrequency treatment system provided and a method of operation thereof.

Human skin tissue is composed of the epidermis and the subcutaneous tissue below it, the epidermal layer having a stratum corneum acts as a biological barrier to the environment, the melanin cells that determine the skin color is present in the base layer. In addition, the lower subcutaneous tissue maintains the structure of the skin by the extracellular protein collagen serves as a support. Collagen is synthesized by fibroblasts and is a protein in which three polypeptides form a helix.

When injured, the body activates a complex remedy, of which fibroblasts are present under the skin and are activated to temporarily enter the extra cellular matrix (ECM) to cover the wound as soon as possible. Secrete. As fibroblasts slowly move around the matrix, attracting fibers to recombine the matrix, making the matrix more rigid, and because of the growth factors contained in the matrix that were initially soft, the fibroblasts expressed contractile proteins by the growth factors, At some point, the fibroblasts stop moving and turn into strong contractile cells, such as popeye, that settle in the matrix and attract the wound edges, resulting in scarring or uneven surface of the skin.

At this time, the collagen fibrous tissue is heated by a predetermined energy source, degeneration of physical properties of the protein matrix occurs at a specific temperature, molecular binding of the matrix is broken, and the condition of the skin is evened, and also the collagen layer is removed. Activation can restore the elasticity of the skin.

By using the above principle, conventionally by cooling the skin surface for wrinkle removal and lifting of the skin, by irradiating energy such as laser, light or high frequency to the lower subcutaneous tissue, by raising the temperature of the subcutaneous tissue A method for remodeling an organization is presented.

In particular, the high frequency current causes very little ionic motion because the vibration width is very short when energizing human tissue, and does not cause electrochemical reaction or electrolysis. When high-frequency electrical energy is applied to the tissues, the molecules constituting the tissues vibrate and rub against each other whenever the direction of current changes, thereby generating bioheat. In addition, the high frequency, unlike other current forms, does not stimulate the sensory and motor nerves, does not cause discomfort or muscle contraction in the human body, there is an advantage that can generate heat energy, this heat energy also enhances the function of the cell It may induce additional effects of increasing blood flow.

In dermatology treatment, high frequency is widely used in various fields such as acne treatment, wrinkle lifting, scar treatment by acne, injection of skin fillers and the like.

However, in the conventional high frequency treatment system for skin treatment, whether the probe is correctly inserted into the affected part of the patient when the doctor performs the high frequency treatment on the patient depends only on the experience and subjective judgment of the doctor.

Hereinafter, the present invention will be described in more detail with reference to Examples. These embodiments are only for illustrating the present invention, and the scope of rights of the present invention is not limited by these embodiments.

Figure 1 shows the configuration of a radio frequency treatment system according to an embodiment of the present invention, Figure 2 shows an equivalent circuit when the radio frequency treatment system according to the present embodiment is applied to a patient, Figure 3 A flowchart illustrating a method of operating a radiofrequency therapy system according to an embodiment. Referring to this embodiment will be described as follows.

As shown in FIG. 1, the radio frequency treatment system according to the present embodiment includes a control unit 110 for controlling an operation of the radiofrequency treatment system; A high frequency generator 120 generating a high frequency voltage under the control of the controller 110; A probe 130 connected to one electrode of the high frequency generator 120; A conductive plate 140 connected to the other electrode of the high frequency generator 120; A resistor (R10) installed between the conductive plate 140 and the ground; When the high frequency voltage is applied through the probe 130 and the conductive plate 140, the detection unit 150 detects a voltage of the node A10 between the conductive plate 140 and the resistor R10 and provides it to the controller 110. ; And a switching unit 160 installed on a path between the node A10 and the control unit 110.

The operation and operation of this embodiment configured as described above will be described in detail with reference to FIGS. 1 to 3.

In general, the human body can be said to be a conductor that can flow current and has a constant impedance component. Therefore, as shown in FIG. 1, when the conductive plate 140 of the radio frequency treatment system is in contact with the back of the patient, the probe 130 is inserted into the skin of the patient, particularly the affected part, and then a high frequency voltage is applied. In addition, the human body of the patient acts as an impedance component so that a high frequency current flows through the human body. Figure 2 shows an equivalent circuit diagram between the radiofrequency treatment system and the human body when applying a high frequency to the human body of the patient. Typically, when the high frequency voltage of 5 ~ 10V, 1MHz, the human body acts as an impedance of about 50 Hz, this embodiment uses this property, which will be described below.

As shown in FIG. 3, first, the high frequency generator 120 under the control of the controller 110 applies the first high frequency voltage to the human body 200 through the probe 130 and the conductive plate 140 (S301). ). As the first high frequency voltage, a high frequency voltage of 5 to 10 V and 0.8 to 1.2 MHz (preferably 1 MHz) is used. At this time, if the probe 130 is correctly or correctly inserted into the affected part of the patient, the human body of the patient serves as the impedance Z10 of about 50 kHz as described above to form the equivalent circuit of FIG. .

Next, the detector 150 detects the voltage of the node A10 (S302). In this case, since the switching unit 160 is turned on, the detector 150 may detect the voltage of the node A10. As described above, if the probe 130 is correctly inserted into the affected part, the human body 200 has an impedance Z10 of about 50 Hz, so that the voltage of the node A10 is approximately the impedance Z10 and the resistance R10. The voltage divided voltage is formed by this.

Next, the controller 110 determines whether the voltage of the node A10 is equal to or greater than a preset reference voltage (S303), and if so, through the step S304, a high frequency shot mode for generating a high frequency voltage. If not, complete the operation. In other words, if the probe 130 is not correctly inserted into the affected part of the patient, since the circuit path through the impedance Z10 of FIG. 2 will not be generated, the voltage of the node A10 is almost grounded. Will be equal to the voltage of However, if the probe 130 is correctly inserted into the affected part of the patient, since the circuit path through the impedance Z10 of FIG. 2 will be generated, the voltage of the node A10 is approximately equal to the impedance Z10. It will be the voltage divided by the resistor R10. Accordingly, the controller 110 determines whether the probe 130 is correctly inserted into the affected part by checking whether the magnitude of the voltage of the node A10 detected by the detector 150 is equal to or greater than a preset reference voltage. can do. The resistance value of the resistor R10 may be freely selected by the user according to the system, and the reference voltage may also be changed according to the system.

Next, when the voltage of the node A10 is equal to or greater than the reference voltage, the controller 110 opens the switching unit 160 before entering the high frequency shot mode (S304). The reason is that the high frequency voltage applied for the high frequency treatment is typically about 40 to 100V, which is much higher than the first high frequency voltage and no longer needs to detect the voltage of the node A10, thus opening the corresponding path. It is to.

Subsequently, the controller 110 enters a high frequency shot mode for generating a high frequency voltage (S305). The high frequency shot mode refers to a mode in which a high frequency voltage for treatment is applied. In this mode, a high frequency for treatment is applied when a doctor operates a footswitch for applying high frequency. In this case, the high frequency shot mode includes a main shot and at least one sub shot or a side shot. The main shot is the first shot to apply a high frequency voltage during the high frequency shot mode, and is a shot that plays a main role in treating inflammation such as skin lesions. The auxiliary shot is a shot for applying a high frequency voltage at least once after the main shot, and serves to stabilize the affected area treated by the main shot. A high frequency voltage of 40V to 100V is typically applied as the auxiliary shot, and the output of the high frequency voltage of the main shot is 10 to 40V higher than that of the high frequency voltage of the auxiliary shot.

Next, when the high frequency shot mode is completed (S306), the controller 110 turns on the switching unit (160) (S307). That is, when the high frequency shot mode is completed and the probe 130 is separated from the affected part, the system is prepared again to resume the step S301 by turning on the switching unit 160 again.

On the other hand, in the present embodiment, the probe 130 includes a setting button (not shown) for setting the high frequency shot mode, which is intended to increase user convenience.

As described above, the radiofrequency treatment system having a safety function and a method of operating the same according to the present invention allow the radiofrequency voltage to be applied only when the probe is correctly inserted into the affected part of the patient in the radiofrequency treatment system, thereby causing a radiation error of the radiofrequency voltage during the radiofrequency treatment. It can suppress unnecessary pain of the patient and reduce the burden on the practitioner.
