Description

{DEVICE FOR APPLYING RADIO FREQUENCY ENERGY TO TISSUE}

The present invention relates to a high-frequency device for irradiating high-frequency energy to a woman's vagina or anus, and more specifically, to a high-frequency device for applying high-frequency energy to tissue by applying high-frequency to an electrode inserted into a woman's vagina or anus and penetrating or contacting the inner wall tissue, thereby applying deep heat to the inner wall of the vagina or anus and the tissue surrounding it, thereby inducing collagen remodeling and improving the elasticity of the vaginal or anal tissue.

Due to pregnancy, childbirth, and aging, women experience various changes in their vaginas, including the muscles surrounding the vagina, which is the organ connecting the vulva and the uterus, becoming more stretched, the uterus saggy, and the wrinkles in the vaginal mucosa disappearing.

Such changes in a woman's quality of life can significantly reduce sexual satisfaction in married life and, in severe cases, can lead to sexual dysfunction. In particular, when the vagina stretches and becomes exposed to the outside, it becomes vulnerable to infections from the outside, making it easy for various viruses, fungi, and bacteria to penetrate the vagina, which can lead to vaginitis and other infections.

In the case of the anus, various infections or anal diseases can occur due to the stretching of the internal tissues.

In order to resolve these female diseases or anal diseases, it is necessary to improve the tissues, such as strengthening or restoring the muscles inside the vagina or anus of women. Medical devices for this purpose include laser treatment devices and high-frequency treatment devices.

For example, in the case of improving the quality of a woman's vagina, a laser device for improving the quality of a woman's vagina is a structure that irradiates a laser to the inner wall of a woman's vagina to cause artificial burns, thereby inducing degeneration and regeneration of the vaginal tissue due to the burns, thereby strengthening or restoring the vaginal muscles. Prior art documents regarding such laser devices include Patent Publication No. 10-1363550 (Laser-based Vaginal Treatment Device), etc.

In addition, a high-frequency device for treating the vagina of a woman forms a high-frequency electrode surface on the outer surface of a rod-type body inserted into the vagina, places the electrode surface in contact with the vaginal wall, and applies high-frequency energy to the vaginal wall in contact with the electrode surface to cause an artificial burn and regenerate vaginal tissue in the process of the area naturally healing. Prior art documents regarding such a high-frequency device include Patent Publication No. 10-2016-0063784 (Vaginal Treatment Device Using High Frequency), etc.

However, since the vaginal wall contains a considerable number of capillaries, applying energy to the vaginal wall can cause significant bleeding, and the tissues inside the anus can also bleed. Therefore, a technology is needed that can apply energy to the tissues inside the vagina or anus while controlling such bleeding.

The specific details of a high-frequency device for applying high-frequency energy to a tissue according to the present invention will be described in more detail with reference to the drawings.

First, an example of a high-frequency device for applying high-frequency energy to a tissue according to one embodiment of the present invention will be described with reference to FIGS. 1 and 2.

FIG. 1 (a) is a drawing showing an example of the operation of a needle type electrode portion of a high-frequency device for applying high-frequency energy to tissue according to one embodiment of the present invention, and FIG. 1 (b) is a drawing showing an example of the operation of a contact electrode type electrode portion of a high-frequency device for applying high-frequency energy to tissue according to another embodiment of the present invention. And FIG. 2 is a block diagram showing a control system of a high-frequency device for applying high-frequency energy to tissue according to one embodiment of the present invention.

The high-frequency device for applying high-frequency energy to tissue according to the present invention applies high-frequency energy to tissue inside a woman's vagina or anus, that is, muscle tissue of the inner wall of the vagina or anus and tissue beneath the inner wall, to increase the elasticity of stretched or relaxed tissue.

Therefore, the high-frequency device for applying high-frequency energy to a tissue according to the present invention basically has a part that can be inserted into a woman's vagina or anus.

Although (a) and (b) of FIG. 1 illustrate a high-frequency device that applies high-frequency energy to the vaginal wall using a body inserted into the vagina, the high-frequency device according to the present invention includes a high-frequency device that applies high-frequency energy not only to the vagina but also to the inside of the anus.

As described above, the present invention comprises an insertion body as a part to be inserted into the vagina or the anus. Since the length of the vagina is usually longer than the length of the anus, the insertion body of a high-frequency device used in the vagina can be formed longer than the insertion body of a high-frequency device used in the anus.

That is, whether the present invention is implemented as a high-frequency device for applying high-frequency energy to a vagina or as a high-frequency device for applying high-frequency energy to anus, the basic configuration and operating principles may be substantially the same.

Accordingly, the basic configuration and operating principle of a high-frequency device for applying high-frequency energy to a vagina as illustrated in (a) and (b) of FIG. 1 can be substantially equally applied to a high-frequency device for the anus, although not separately illustrated in the drawings. Therefore, the following will primarily describe specific details of the present invention from the perspective of a high-frequency device for applying high-frequency energy to a vagina.

A high-frequency device according to one embodiment of the present invention includes an applicator (AP) that is inserted into the vagina of a subject to apply high-frequency energy, and a main body (not shown) that is connected to the applicator (AP) and supplies energy.

As illustrated in (a) and (b) of FIG. 1, an applicator (AP) of a high-frequency device according to one embodiment of the present invention comprises an insertion body (100) that is inserted into the vagina (V) of a subject, a rear end (120) at the rear end of the insertion body (100), and an electrode portion (142 or 144) that applies high-frequency energy by invading or contacting the tissue of the vaginal wall (W) at one side of the front end of the insertion body (100).

It is preferable that the above insertion body (100) be in a shape that can be inserted into the vagina (V), and the insertion body (100) may be implemented in a straight bar shape, but as shown in (a) and (b) of FIG. 1, it is easy to make the electrode part (142 or 144) of the insertion body (100) adhere to the vaginal wall (W) by implementing it in a curved shape.

A driving motor (not shown) capable of moving the electrode part may be provided internally at the rear end (120) of the insertion body (100).

Even when the present invention is implemented as a high-frequency device for applying high-frequency energy to the anus, it may have an insertion body of a shape that can be inserted into the anus, and its specific form may be different in shape and length, etc. from the insertion body for insertion into the vagina illustrated in (a) and (b) of FIG. 1, but it is the same in that the electrode portion is provided at the front end of the insertion body and is configured to be in close contact with the inner wall of the anus to apply high-frequency energy.

Meanwhile, the electrode part provided in the insertion body (100) as described above may be implemented as a needle electrode part (142) in the shape of a needle that can invade the vaginal wall (W) tissue as shown in (a) of FIG. 1, or may be implemented as a contact electrode part (144) that contacts the vaginal wall (W) tissue as shown in (b) of FIG. 1.

The needle electrode portion (142) as shown in (a) of Fig. 1 is provided inside the insertion body (100) and can be implemented in a configuration in which it can be protruded from the inside of the insertion body to the outside by the driving force of a driving motor (not shown) provided inside the rear end (120).

The needle electrode part (142) provided inside the insertion body (100) can be configured to move (movement by protruding and returning from the inside of the insertion body to the outside) by means of a driving shaft (not shown) of a driving motor and a driving force transmission means (not shown) connected thereto and transmitting the driving force of the driving shaft to the needle electrode part (142). The driving motor, driving shaft, driving force transmission means, etc. as described above are collectively referred to as a "driving part."

As shown in (b) of FIG. 1, the contact electrode part (144) is an electrode that comes into contact with the vaginal wall (W), so it does not have to be implemented in a configuration that moves to protrude from the inside of the insertion body (100) to the outside. However, more preferably, in order for the contact electrode part (144) shown in (b) of FIG. 1 to come into closer contact with the vaginal wall (W), it may be implemented in a configuration in which the contact electrode part (144) moves to protrude further into the vaginal wall (W) by the driving part as described above.

Meanwhile, an applicator (AP) as illustrated in (a) and (b) of FIG. 1 may be configured to be connected to a main body, although not illustrated in the drawing, and the main body may be equipped with various devices for driving and operating the applicator (AP), including a power supply unit for supplying power to the applicator (AP), a high-frequency generator for generating high-frequency energy, an input unit (a display and buttons or a touch panel) for allowing the practitioner to input, operate, and set various treatment parameters, and a control unit for controlling the power supply unit, the high-frequency generator, etc., and may be connected to an operation switch (for example, a foot switch that the practitioner can operate by stepping on it with his or her foot) for allowing the practitioner to control the operation of the applicator (AP), etc.

As shown in FIG. 2, the control unit (200), input unit (210), high-frequency oscillator unit (220), pulse generator unit (230), etc., can all be provided in a main body connected to the applicator, the driving unit (160) can be provided in the applicator, and the operation switch (250) can be provided connected to the main body.

The above input unit (210) is a part implemented as a touch panel or the like that allows the operator to input, manipulate, and set various treatment parameters, and the above high-frequency oscillation unit (220) is a component that generates a high-frequency electric signal to transmit high-frequency energy to an electrode unit (which may be a needle electrode unit or a contact electrode unit) provided in the insertion body of the applicator under the control of the control unit (200).

The above pulse generating unit (230) is a component that generates pulses having a set size and interval at a set number of times under the control of the control unit (200).

Accordingly, when the operator inputs and sets the output and application time of high-frequency energy for generating deep heat in the tissue of the vaginal wall through the input unit, and operates the operation switch while holding the applicator (AP) as shown in (a) of FIG. 1 and inserting the insertion body (100) into the vagina (V), the driving unit inside the applicator (AP) protrudes the needle electrode unit (142) so that the needle electrode unit (142) invades the vaginal wall (W), and the control unit controls the high-frequency oscillation unit according to the output and application time set by the operator to transmit high-frequency energy to the needle electrode unit (142), thereby generating deep heat (152) in the tissue of the vaginal wall (W).

Likewise, in the case illustrated in (b) of Fig. 1, when the insertion body (100) is inserted into the vagina (V) and the contact electrode part (144) is in close contact with the vaginal wall (W) and the operation switch is operated, the control part controls the high-frequency oscillation part according to the output and application time set by the operator, and high-frequency energy is transmitted to the contact electrode part (144) to generate deep heat (154) in the tissue of the vaginal wall (W).

At this time, bleeding may occur from the vaginal wall tissue due to invasion of the vaginal wall tissue by the needle electrode part, and to prevent this, the control part may cause energy for controlling bleeding of the vaginal wall (or anal wall) to be applied through the electrode part when the application of high-frequency energy for generating deep heat of the electrode part as described above is terminated.

That is, when the application time of the high-frequency energy for the above-described deep heat generation ends, the control unit controls the pulse generation unit so that a pulse having a preset output and a short time interval as an output capable of thermally coagulating the tissue of the vaginal wall (or the anal wall) is repeatedly applied to the tissue in contact with the electrode unit a preset number of times, thereby controlling bleeding in the tissue due to the above-described deep heat generation.

Changes in tissues as a result of applying high-frequency energy to the tissues of the vaginal or anal wall by the electrodes are shown in Fig. 3. Fig. 3 shows the degree of tissue change according to the magnitude of high-frequency energy applied to the tissues by the electrodes.

In Fig. 3, the change state (MH1) of the tissue according to the size of the high-frequency energy as the needle electrode part (142) applies high-frequency energy to the tissue of the vaginal wall (W), and the change state (MH2) of the tissue according to the size of the high-frequency energy as the contact electrode part (144) applies high-frequency energy to the tissue of the vaginal wall (W) are shown.

When an electrode applies high-frequency energy to a tissue, heat is generated in the tissue. The greater the magnitude of the high-frequency energy, the greater the heat generated in the tissue. As shown in Fig. 3, changes in the tissue appear in stages depending on the magnitude of the heat generated in the tissue according to the high-frequency energy.

As shown in Fig. 3, changes from H1 to H5 can occur depending on the size of heat generated in the tissue by high-frequency energy.

H1 is the heating stage where deep heat is generated in the tissue and can occur at a temperature of approximately 40 to 45℃. H2 occurs at a temperature of approximately 45 to 58℃ and is the protein denaturation stage.

H3 occurs at a temperature of about 60 to 80℃ and is the coagulation stage, H4 occurs at a temperature of over 100℃ and is the vaporization stage, and H5 occurs at a temperature of over 200℃ and is the carbonization stage.

When it reaches the vaporization state of H4 and the carbonization state of H5, the corresponding tissue becomes necrotic and is removed, and can be used mainly when ablating tumor cell tissue.

The control unit of the high-frequency device according to one embodiment of the present invention can control the high-frequency oscillation unit so that high-frequency energy is generated according to the output and application time set by the operator in an output range capable of generating deep heat, i.e., deep heat of stage H1 or stage H2 as shown in FIG. 3, in the tissue of the inner wall of the vagina through the electrode unit that has invaded or contacted the tissue of the inner wall of the vagina.

And, when the set application time of high-frequency energy that generates deep heat in the tissue ends, the control unit repeatedly applies a very short pulse with a high output capable of thermally coagulating the tissue a preset number of times, thereby thermally coagulating the tissue in contact with the electrode unit (thermal coagulation at stage H3 shown in Fig. 3), thereby preventing bleeding from occurring in the tissue through the thermal coagulation.

The output pattern of high-frequency energy applied to the vaginal wall or the anal wall through the electrode portion of the high-frequency device according to one embodiment of the present invention is as shown in FIG. 4.

FIG. 4 is a graph showing the output (vertical axis) versus the application time (horizontal axis) of high-frequency energy applied through an electrode portion of a high-frequency device according to one embodiment of the present invention.

As illustrated in FIG. 4, a high-frequency device according to one embodiment of the present invention applies high-frequency energy (TE) in a range that generates deep heat in the tissue of the vaginal wall or the anal wall through an electrode portion that penetrates or contacts the vaginal wall or the anal wall, and then applies a plurality of pulses of high-frequency energy (CA) for bleeding control in a range that generates thermal coagulation for controlling bleeding within the tissue, so that bleeding within the tissue due to the application of high-frequency energy can be prevented.

The control unit of the high-frequency device according to one embodiment of the present invention can control the high-frequency oscillation unit to generate high-frequency energy according to the output (Pa) and application time (ta) set by the operator in an output range capable of generating deep heat (stage H1 or H2 of FIG. 3) in the tissue as high-frequency energy (TE) for generating deep heat in the tissue of the vaginal wall or the anal wall.

And, when the application of high-frequency energy (TE) for generating deep heat in the tissue is terminated, the control unit can control the pulse generation unit so that a pulse having an output (Pp) capable of thermally coagulating (step H3 of FIG. 3) the tissue contacted with the electrode unit as energy (CA) for controlling bleeding is repeatedly applied a preset number of times.

As illustrated in FIG. 4, for high frequency energy (TE) for generating deep heat in a tissue, the control unit can apply high frequency energy to the tissue according to a selected output Pa and application time ta within a range of output and application time so as to generate heat in the range of 40°C to 45°C in the tissue of the vaginal wall or the anal wall.

For example, the operator may select and set the output and application time within a range of 0.1 W to 3 W and a time range of 500 ms to 10,000 ms as the range of high-frequency energy for generating deep heat in the tissue. That is, Pa may be an output selected within a range of 0.1 W to 3 W, and ta may be an application time selected within a time range of 500 ms to 10,000 ms.

When the application of high-frequency energy to the tissue is completed, a pulse of energy of a considerably high output (Pp) applied for a very short time (tp) is applied multiple times at a time interval of td to cause thermal coagulation in the tissue in contact with the electrode part so as to prevent bleeding from occurring in the tissue.

The application of short, strong, repetitive pulses that induce thermal coagulation may contribute more to tissue regeneration as well as bleeding control.

However, since the pulse energy (CA) as described above applies high output energy, it may cause excessive thermal damage to the tissue. Therefore, it is desirable to induce hemostasis without excessive thermal damage by making the application time very short.

For example, a pulse having a preset output (Pp) within the range of 5 W to 20 W and a preset application time (tp) within the range of 1 ms to 100 ms, which can coagulate tissue, can be repeatedly applied to the tissue in contact with the electrode portion multiple times at preset short time intervals (td).

Here, the number of repetitions of the pulses that cause thermal coagulation as described above may be applied at a number of repetitions of 2 to 10, preferably 3 to 5, because if the number of repetitions of the pulses is too small, the hemostatic effect may be reduced, and if the number of repetitions of the pulses is too large, thermal damage to the tissue may be excessive.

Additionally, the time interval (td) of each pulse can be set to be equal to or shorter than the pulse application time tp.

As described above, the application of pulse energy (CA) cannot be set through the input section of the main body, but can be set only in the factory mode, and the input section of the main body can be configured so that the operator can select and set only the parameters for high-frequency energy for generating deep heat in the tissue.

Meanwhile, a method for controlling a high-frequency device according to one embodiment of the present invention will be described with reference to FIG. 5.

The practitioner can select and set the output, application time, etc. of high-frequency energy for high-frequency treatment, which can generate deep heat in the tissue of the vaginal wall or the tissue of the anal wall (S100). At this time, the practitioner can select the output or application time of high frequency energy through the input unit of the main body.

When the insertion body of the applicator is inserted into the vagina or anus of the subject by the practitioner (S110), and the operation switch is operated by the practitioner in that state (S120), the driving unit is driven so that the electrode portion provided on one side of the insertion body can penetrate the needle into the vaginal or anal wall, or the contact electrode portion can be driven so that the contact electrode portion can contact the inner wall (S130).

And, high-frequency energy according to the output and application time set in the above step S100 can be applied to the vaginal wall or anal wall tissue through the electrode unit (S140). As a result of the application of such high-frequency energy, deep heat is generated in the vaginal wall or anal wall tissue.

Once the application of high frequency energy for generating deep heat as described above is completed (S150), a hemostatic effect can be induced by applying multiple pulses of high frequency energy for bleeding control with an output capable of generating thermal coagulation in the tissue (S160).

Here, the application of high frequency energy for deep heat generation at step S140 and the application of high frequency pulse energy at step S160 are as described above with reference to Fig. 4, so a detailed description will be omitted.

As described above, after the application of high-frequency energy to the area where the electrode part has invaded or contacted from step S130 to step S160 is completed (S170), the process from step S130 to step S160 can be repeated by operating the operation switch again at the next position while rotating the insertion body, and in this way, improvement can be made to the vaginal wall or anal wall tissue, and bleeding can be controlled by causing thermal coagulation through multiple short and strong pulses at the end of the application of high-frequency energy that generates deep heat.
