Description

[Technical Field]

[0001] The present invention relates to a therapeutic ultrasonic generator and an ultrasonic therapeutic handpiece including the same, and more particularly to a therapeutic ultrasonic generator and an ultrasonic therapeutic handpiece including the same that can reduce the size of the ultrasonic therapeutic handpiece by simplifying the structure that moves the focus of ultrasonic waves generated by an ultrasonic generator in a circular pattern on the same plane. [Background technology]

[0002] In recent years, as dietary habits have become more Westernized, obesity has rapidly increased and become the biggest cause of damage to the health and beauty of the nation. To treat this, various diet programs and ultrasonic obesity treatment devices have been developed and are widely used. High-intensity focused ultrasound (HIFU) obesity treatment technology was originally used for anti-cancer treatment, non-invasively destroying cancer cells by selectively coagulating internal organ tumors with high temperatures. Solta Medical in the US first developed equipment called Liposonix with HIFU for the treatment of abdominal obesity in humans. The process of fat destruction using HIFU (high intensity focused ultrasound) involves focusing concentrated ultrasound waves on a specific point on fat cells, causing the tissue temperature to instantly rise to 65-100°C, which destroys the tissue. Unlike other dermatological devices, such as lasers and RF devices, HIFU devices induce coagulation necrosis of fat by non-invasively concentrating HIFU energy on selected areas without causing any damage to the surface of the skin. The necrotic fat cells are then naturally eliminated by the body's repair mechanism. A known ultrasonic obesity treatment device is the "High-intensity focused ultrasound generating device for reducing subcutaneous fat layer" in Korean Patent Registration No. 10-1365946 (published on February 24, 2014). The "High-intensity focused ultrasound generating device for reducing subcutaneous fat layer" moves the transducer to the desired point in the X-axis and Y-axis directions, and then pivots around the axis to penetrate ultrasound into the skin. However, the "High-intensity focused ultrasound generating device for reducing subcutaneous fat layer" has a problem that when ultrasound is emitted, ultrasound is emitted in a curved (arc) shape due to the characteristics of the pivot drive, and the energy delivered to the skin decreases as it approaches the periphery, and the focal depth changes, resulting in an inconsistent treatment. To solve this problem, the applicant has proposed a structure for the "therapeutic ultrasound generator" of Korean Patent No. 1649899, ​​which includes a focus rotation unit that moves the focus of ultrasound generated by the ultrasound generator in a circular pattern on the same plane, thereby forming the focus of ultrasound in a circle with a constant radius at a uniform depth within the skin and applying energy uniformly within the radius, thereby improving treatment performance. However, the "therapeutic ultrasonic generator" of Korean Patent No. 1649899 has a structure in which multiple protruding members protruding at different heights contact the top surface of the ultrasonic generator, which not only limits how much it can be reduced in size, but also creates problems in that it is difficult to stably move the focus of the ultrasonic waves generated by the ultrasonic transducer in a circular pattern on the same plane. In addition, the "therapeutic ultrasonic generator" of Korean Patent No. 1649899 has a problem in that the ultrasonic generator rotates at an angle, so that the ultrasonic waves are generated at an angle and the focus is essentially formed on the skin in a diagonal direction. This makes it difficult for the strength of the ultrasonic waves transmitted to the skin, i.e., the output of the ultrasonic waves, to be transmitted to the skin uniformly, and it is difficult to increase the radius of the circle formed on a plane. In addition, the "therapeutic ultrasonic generator" of Korean Patent No. 1649899 has a structure in which multiple protruding members protruding at different heights come into contact with the top surface of the ultrasonic generator, and the ultrasonic generator is rotated in an inclined position, which not only makes the structure complex and increases manufacturing costs, but also creates a torsional moment, requiring a large load to rotate the ultrasonic generator. Summary of the Invention [Problem to be solved by the invention]

[0003] The object of the present invention is to provide a therapeutic ultrasonic generator and an ultrasonic therapeutic handpiece including the same that improve obesity treatment performance by moving the focus of ultrasonic waves in a circular pattern at a uniform depth within the skin to allow the ultrasonic waves to penetrate uniformly into the skin. Another object of the present invention is to provide a therapeutic ultrasonic generator and an ultrasonic therapeutic handpiece including the same, which can easily adjust the output of ultrasonic waves, increase the radius of focus movement, and minimize the load on the motor during operation by rotating the ultrasonic transducer at an eccentric position on a plane and moving the focus of ultrasonic waves in a circular pattern on the same plane. Another object of the present invention is to provide a therapeutic ultrasound generator and an ultrasonic therapeutic handpiece including the same, which can reduce the size of the ultrasonic therapeutic handpiece by simplifying the structure that moves the focus of ultrasound generated by the ultrasonic transducer unit in a circular pattern on the same plane, and which can perform ultrasonic therapy on localized areas of the patient's skin, such as under the eyes.

[0007] The present invention will now be described in further detail. A preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings as follows. Prior to a detailed description of the present invention, the terms and phrases used in the following specification and claims should not be interpreted in a limited manner to their ordinary or dictionary meanings. Therefore, it should be understood that the embodiment described in this specification and the configurations shown in the drawings are merely the most preferred embodiment of the present invention and do not represent the entire technical concept of the present invention. Therefore, it should be understood that there may be various equivalents and modifications that can replace them at the time of filing this application. FIG. 1 is a perspective view showing an embodiment of an ultrasonic treatment handpiece according to the present invention, and FIG. 2 is an exploded perspective view showing an embodiment of an ultrasonic treatment handpiece according to the present invention. 1 and 2, the ultrasonic treatment handpiece according to the present invention includes a main body housing part 100 to which the therapeutic ultrasonic generator according to the present invention is detachably coupled. One embodiment of the therapeutic ultrasonic generator according to the present invention includes a cartridge housing portion 200 in which an ultrasonic transducer portion 300 is located and which has a window portion 203 at the bottom through which ultrasonic waves pass. The therapeutic ultrasonic generator according to the present invention irradiates the skin with ultrasonic waves generated by the ultrasonic transducer unit 300 in the cartridge housing unit 200 by passing the ultrasonic waves through the window unit 203 located at the bottom of the cartridge housing unit 200, and is detachably connected to the main body housing unit 100 of the ultrasonic therapeutic handpiece according to the present invention. The ultrasonic treatment handpiece according to the present invention is connected to the control body 1000 by a handpiece cable body 1100, which includes a power cable, a medium supply line for circulating the medium within the cartridge housing part 200, and a medium discharge line. The handpiece cable body 1100 and the control body 1000 can be implemented by various modifications to known examples in known ultrasonic treatment devices, so further detailed description will be omitted. The ultrasonic transducer unit 300 has a preset number of uses, and when the number of uses of the ultrasonic transducer unit 300 of the therapeutic ultrasonic generator according to the present invention is reached, the ultrasonic transducer unit 300 is replaced with a new, unused unit. That is, the cartridge housing part 200 is detachably coupled to the main body housing part 100, and can be replaced after the ultrasonic transducer part 300 has been used a predetermined number of times. An embodiment of a therapeutic ultrasound generating device according to the present invention will be described in detail below. The main body housing portion 100 is provided with a cartridge locking device 101 that can be used to lock the cartridge housing portion 200 in place. The cartridge locking device 101 is elastically supported by a spring, and its wedge-shaped engaging portion engages with an engaging groove located inside the cartridge housing, thereby fixing the combined state of the cartridge housing portion 200. When pressed down, the engaging portion disengages from the engaging groove, allowing the cartridge housing portion 200 to be separated. The cartridge housing part 200 can be maintained in a coupled state with or separated from the main body housing part 100 by applying a known releasable locking structure other than the cartridge locking device 101, so further detailed description will be omitted. A handle 110 is located on one side of the main body housing 100 so that the practitioner can hold it with their hand. The handle portion 110 includes a handle connecting portion 111 that is bent and positioned on the upper side of the main body housing portion 100, and a handle main body 112 that is bent from the handle connecting portion 111 and positioned downward. The practitioner can grip the handle body 112, which is bent and extends downward from the handle connecting portion 111, and easily bring the window portion 203 of the cartridge housing portion 200 into close contact with the skin to perform treatment. The handle portion 110 has a shape that bends upward and then bends and extends downward, and is designed to be grasped by the downward extending portion, i.e., the handle body 112, which minimizes the load on the practitioner during treatment and allows the window portion 203 of the cartridge housing portion 200 to easily fit closely to the skin during treatment. Meanwhile, the therapeutic ultrasound generator according to the present invention includes a cartridge housing part 200 having a window part 203 at the bottom through which ultrasound can pass, and an ultrasound transducer part 300 located within the cartridge housing part 200 and generating ultrasound from the bottom side. The window portion 203 is made of a transparent or translucent material that transmits ultrasonic waves, and is made of a known material that transmits ultrasonic waves, so further detailed description will be omitted. The cartridge housing portion 200 includes an upper housing portion 201 detachably coupled to the main body housing portion 100 , and a housing sealing cap portion 202 detachably coupled to the lower side of the upper housing portion 201 . A window portion 203 is formed on the underside of the housing sealing cap portion 202 in a size that allows contact with the patient's skin to perform ultrasonic treatment. The cartridge housing portion 200 has a sealed structure and is filled with an ultrasonic wave transmitting medium. The ultrasonic wave transmitting medium is, for example, an insulating liquid, but the insulating liquid can be variously modified to a known insulating liquid that does not conduct electricity, so further detailed description will be omitted. The ultrasonic transmission medium not only serves to transmit ultrasonic waves but also to cool the patient's skin through the window portion 203 that comes into contact with the skin. A cartridge board part 201a that seals the inside of the cartridge housing part 200 is located at the top of the cartridge housing part 200, and a medium supply protrusion part 210 and a medium discharge protrusion part 220 are located protruding from the upper surface of the cartridge board part 201a to circulate the ultrasonic transmission medium. An eccentric shaft part 500 is provided on the upper surface of the ultrasonic transducer part 300 so as to stand eccentrically from the center of the body of the ultrasonic transducer part 300 and connected to the rotary motor part 400 . The eccentric shaft portion 500 is erected in the center of the cartridge housing portion 200 inside the cartridge housing portion 200, and its lower end portion is connected to the upper surface of the ultrasonic transducer portion 300 at an eccentric position. The eccentric shaft 500 has an upper end portion that protrudes from the upper surface of the cartridge board 201 a and is connected to the rotary motor 400 when the cartridge housing 200 is coupled to the main body housing 100 . The rotary motor unit 400 is connected to the eccentric shaft unit 500 and transmits a rotational force to the eccentric shaft unit 500 to rotate the ultrasonic transducer unit 300 around the eccentric shaft unit 500 . The ultrasonic transducer section 300 has a lower surface that emits ultrasonic waves and is positioned in a direction perpendicular to the window section 203, and emits ultrasonic waves from a direction perpendicular to the window section 203. The rotary motor section 400 is, for example, located inside the main body housing section 100, and although not shown, may be attached to the upper surface of the cartridge board section 201a. When the cartridge housing 200 is coupled to the lower part of the main body housing 100, a portion of the eccentric shaft 500 protruding from the upper surface of the cartridge board 201a is connected to the rotation motor 400. The rotary motor unit 400 is located within the main body housing unit 100, and when the cartridge housing unit 200 is attached to the lower part of the main body housing unit 100, it is connected to the eccentric shaft unit 500. Since the rotary motor unit 400 is not replaced together with the cartridge housing unit 200 when the ultrasonic transducer unit 300 reaches the end of its service life, costs can be reduced. Although not shown, the rotary motor unit 400 may be attached to the cartridge housing unit 200 and may have a structure that allows it to be replaced together with the cartridge housing unit 200 when the cartridge housing unit 200 is replaced depending on the service life of the ultrasonic transducer unit 300. The eccentric shaft portion 500 is positioned so as to protrude from the upper surface of the cartridge board portion 201a, but is positioned so as to be rotatable. The eccentric shaft portion 500 is rotatably positioned so as to pass through the cartridge board portion 201a, and can be realized using a known seal structure for sealing the rotating shaft, so a more detailed description will be omitted. The eccentric shaft portion 500 includes a connecting shaft portion 510 that protrudes from the upper portion of the cartridge housing portion 200 and is connected to the rotary motor portion 400, and the shaft of the rotary motor portion 400 is provided with a shaft adapter portion 410 into which the connecting shaft portion 510 is inserted and connected to the connecting shaft portion 510. The shaft adapter part 410 has a shaft insertion part that is open at the bottom side so that the connecting shaft part 510 can be inserted therein. The connecting shaft part 510 is a shaft with a polygonal cross section, and the shaft insertion part is, for example, a polygonal insertion groove part that corresponds to the connecting shaft part 510. The connecting shaft portion 510 is inserted into the polygonal insertion groove of the shaft insertion portion, and receives the rotational force of the rotary motor portion 400 to rotate. Inside the main body housing part 100, when the cartridge housing part 200 is coupled, there are located a supply pipe connection part (not shown) and a discharge pipe connection part (not shown) which connect the medium supply protrusion pipe part 210 and the medium discharge protrusion pipe part 220 to a medium circulation part (not shown) located in the control main body 1000 which controls the operation of the ultrasonic treatment handpiece. The control body 1000 can be implemented in various ways as a known ultrasonic treatment device including a control unit that controls the operation of an ultrasonic treatment handpiece and a medium circulation unit that circulates an ultrasonic transmission medium, so further detailed explanation will be omitted. Although not shown, the medium circulation unit may be variously modified into a known cooling water circulation structure including a medium storage tank, a medium supply line connecting the medium storage tank to the supply pipe connection unit 120, a medium discharge line connecting the medium storage tank to the discharge pipe connection unit 130, a valve located in the medium supply line, and a medium cooler located in the medium storage tank, and therefore further detailed description thereof will be omitted. The supply pipe connection portion (not shown) has a first protruding pipe insertion portion into which the medium supply protruding pipe portion 210 is inserted, and the discharge pipe connection portion (not shown) has a second protruding pipe insertion portion into which the medium discharge protruding pipe portion 220 is inserted. As an example, the medium supply protruding pipe section 210 is inserted into the first protruding pipe insertion section, and the flow path is opened and connected to the medium supply line section, and the medium discharge protruding pipe section 220 is inserted into the second protruding pipe insertion section, and the flow path is opened and connected to the medium discharge line section. It is clear that the medium supply protruding pipe portion 210 and the supply pipe connection portion (not shown), and the medium discharge protruding pipe portion 220 and the discharge pipe connection portion (not shown) can be implemented by various modifications to a known pipe connection structure that connects two pipes to each other and includes a valve that is opened when connected. When the cartridge housing part 200 is coupled to the main body housing part 100, the connecting shaft part 510 of the eccentric shaft part 500 is inserted into the shaft insertion part of the shaft adapter part 410, thereby connecting the eccentric shaft part 500 to the shaft 1 of the rotary motor part 400, the medium supply protrusion pipe 210 is inserted into the first protrusion pipe insertion part of the protrusion pipe connecting part 120, thereby connecting to the medium circulation part of the control main body 1000, and the medium discharge protrusion pipe part 220 is inserted into the second protrusion pipe insertion part of the discharge pipe connecting part 130, thereby connecting to the medium circulation part of the control main body 1000. In addition, a pair of first main power supply terminals 230 for supplying power to the ultrasonic transducer unit 300 is provided on the upper surface of the cartridge board unit 201a, and although not shown, the pair of first main power supply terminals 230 are connected to the main body housing unit 100, and a second main power supply terminal connected to the control main body 1000 by the handpiece cable body 1100 is located inside. The first main power supply terminal 230 is, for example, a protruding terminal that protrudes from the upper surface of the cartridge housing portion 200, i.e., the upper surface of the cartridge board portion 201a, and the second main power supply terminal is, for example, an insertable terminal into which the first main power supply terminal 230 can be inserted and connected. When the cartridge housing part 200 is coupled to the main body housing part 100, the pair of first main power supply terminals 230 are inserted into the pair of second main power supply terminals and connected to each other, and the ultrasonic transducer part 300 is connected to the control body 1000 via the handpiece cable body 1100, so that it can receive power from the control body 1000 and control its operation. On the other hand, FIG. 3 is a cross-sectional view showing one embodiment of a therapeutic ultrasonic generator according to the present invention, FIG. 4 is a cross-sectional view showing an enlarged view of part A in FIG. 3, and FIG. 5 is a partially enlarged bottom perspective view showing one embodiment of a therapeutic ultrasonic generator according to the present invention. An embodiment of a therapeutic ultrasound generating device according to the present invention will be described in further detail below with reference to FIGS. In one embodiment of the therapeutic ultrasonic generator according to the present invention, the ultrasonic transducer unit 300 is connected to the rotary motor unit 400 by an eccentric shaft unit 500 that is eccentric from the center of the body of the ultrasonic transducer unit 300 . When the ultrasonic transducer unit 300 rotates eccentrically around the eccentric shaft unit 500, the focus of the ultrasonic waves moves in a circle having a predetermined radius at the shaft center of the rotary motor unit 400. The ultrasonic transducer unit 300 is connected at an eccentric position to the eccentric shaft unit 500, which is rotated by the rotary motor unit 400, and rotates on a plane, so that the focus of the ultrasonic waves generated by the ultrasonic transducer unit 300 moves in a circle on the same plane. The ultrasonic transducer section 300 irradiates the window section 203 with ultrasonic waves from a direction perpendicular to the window section 203 . The ultrasonic wave generating surface of the ultrasonic transducer unit 300 is positioned parallel to the window unit 203 and irradiates ultrasonic waves in a direction perpendicular to the window unit 203. The ultrasonic transducer unit 300 rotates around an eccentric shaft unit 500 that is eccentric from the center of rotation of the rotary motor unit 400, causing the focus of the ultrasonic waves to move in a circle on a plane. In other words, the therapeutic ultrasound generator according to the present invention moves the ultrasound focus in a circle on the same plane at a predetermined radius while positioning the focus at a uniform depth within the skin, thereby forming the movement path of the focus in a circle on the plane, thereby enabling energy to be applied uniformly within the radius of the movement of the focus. In addition, in the therapeutic ultrasonic generator according to the present invention, the ultrasonic transducer unit 300 is rotated around the eccentric shaft unit 500 with the ultrasonic generating surface of the ultrasonic transducer unit 300 positioned alongside the window unit 203, so that the focal point movement path is formed as a circle on a plane, making it easy to adjust the ultrasonic output and selectively designing the focal point movement radius to be narrow or wide. Meanwhile, one embodiment of the therapeutic ultrasonic generator according to the present invention further includes a power supply protruding terminal part 600 that protrudes from the upper side of the ultrasonic transducer part 300 to supply power to the ultrasonic transducer part 300, and a power supply board part 700 that is located at a distance from the upper side of the ultrasonic transducer part 300 within the cartridge housing part 200 and to which the power supply protruding terminal part 600 is connected. A ring-shaped electrode pattern 710 is located on the lower surface of the power supply board 700 and is connected to the power supply by a power cable. When the ultrasonic transducer part 300 rotates around the eccentric shaft part 500, the power supply protruding terminal part 600 moves in a circle with its upper end side connected to the ring-shaped electrode pattern 710, thereby stably supplying power to the ultrasonic transducer part 300. The ring-shaped electrode pattern 710 is electrically connected to the first main power supply terminal 230 protruding from the upper surface of the cartridge board part 201a by a power cable via a terminal positioned through the power supply board part 700. As a result, when the cartridge housing part 200 is coupled to the main body housing part 100, the pair of first main power supply terminals 230 are inserted into the pair of second main power supply terminals and connected to each other, and the ring-shaped electrode pattern 710 is connected to the control main body 1000 via the handpiece cable body 1100 to receive power from the control main body 1000, and can stably supply power to the ultrasonic transducer part 300 via the power supply protruding terminal part 600. The power supply protruding terminal portion 600 is held in elastic contact with the ring-shaped electrode pattern 710, and when the ultrasonic transducer portion 300 rotates around the eccentric shaft portion 500, it moves in a circle while being stably connected to the ring-shaped electrode pattern 710. As an example, the power supply protruding terminal portion 600 includes a jig pin member 610 that is connected to the ring-shaped electrode pattern 710 and electrically connected to the ultrasonic transducer portion 300 by an electric wire, a pin insertion member 620 that is located on the upper surface of the ultrasonic transducer portion 300 and in which the jig pin member 610 is positioned so that it can move up and down, and a pin support spring member 630 that is located within the pin insertion member 620 and elastically supports the jig pin member 610. The jig pin member 610 is elastically supported by the pin support spring member 630 and the upper end side thereof contacts the ring-shaped electrode pattern 710 . When the ultrasonic transducer unit 300 rotates eccentrically around the eccentric shaft unit 500 by the rotary motor unit 400, the jig pin member 610 is elastically supported by the pin support spring member 630 and moves in a circle along the ring-shaped electrode pattern 710 with its upper end side in contact with the ring-shaped electrode pattern 710, thereby enabling stable power supply to the ultrasonic transducer unit 300. More specifically, the power supply protruding terminal portion 600 includes a cathode protruding terminal portion 600a and an anode protruding terminal portion 600b that are positioned at a distance different from the eccentric shaft portion 500, and the ring-shaped electrode pattern 710 includes a first electrode pattern 711 having a radius corresponding to the radius of rotation of the cathode protruding terminal portion 600a and a second electrode pattern 712 having a radius corresponding to the radius of rotation of the anode protruding terminal portion 600b. The cathode protruding terminal portion 600a and the anode protruding terminal portion 600b are in contact with two first electrode patterns 711 and two second electrode patterns 712 of different radii, respectively, and the jig pin member 610 is positioned in elastic contact therewith, and moves in a circle while in contact with the ring-shaped first electrode pattern 711 and the second electrode pattern 712, respectively, thereby enabling a stable supply of power to the ultrasonic transducer portion 300. Furthermore, since the ultrasonic transmission medium is an insulating liquid, even if the power supply protruding terminal portion 600 is exposed inside the cartridge housing portion 200, no short circuit occurs, and power can be stably supplied into the ultrasonic transducer portion 300 with the cathode protruding terminal portion 600a and the anode protruding terminal portion 600b connected to the two exposed ring-shaped electrode patterns 710, the first electrode pattern 711 and the second electrode pattern 712. In addition, one embodiment of the therapeutic ultrasound generator according to the present invention may further include a board position fixing board unit 800 located between the cartridge board unit 201a and the power supply board unit 700 to support the position of the power supply board unit 700, a plurality of first board fixing units 810 having both ends fixed to the cartridge board unit 201a and the board position fixing board unit 800 to support the position of the board position fixing board unit 800, and a plurality of second board fixing units 820 having both ends fixed to the board position fixing board unit 800 and the power supply board unit 700 to support the position of the power supply board 700. The eccentric shaft part 500 passes through the board position fixing board part 800 and the power supply board part 700 and is connected to the upper surface of the ultrasonic transducer part 300 at an eccentric position. The board unit 800 for fixing the board position is connected to the upper surface of the cartridge housing unit 200, i.e., the cartridge board unit 201a, by a plurality of first board fixing parts 810, thereby fixing its position, and the power supply board unit 700 is connected to the board unit 800 for fixing the board position by a plurality of second board fixing parts 820, thereby stably fixing its position. The plurality of first board fixing parts 810 and the plurality of second board fixing parts 820 are formed in a hollow tube shape, and a power cable connecting the ring-shaped electrode pattern 710 and the first main power supply terminal 230 can be wired inside. The power cable connecting the ring-shaped electrode pattern 710 and the first main power supply terminal 230 may be wired through the inside of the plurality of first board fixing parts 810 and the plurality of second board fixing parts 820 and may not be exposed to the outside. 6 is a partially enlarged view showing another embodiment of the therapeutic ultrasonic generator according to the present invention, which further includes an ultrasonic transducer moving unit 900 having an ultrasonic transducer unit 300 movably located at the bottom and an eccentric shaft unit 500 connected to the top. The ultrasonic transducer moving unit 900 moves the ultrasonic transducer unit 300 linearly in the circumferential direction from the center of rotation of the rotary motor unit 400 on its underside, and can adjust the rotation radius of the ultrasonic transducer unit 300 based on the center of rotation of the rotary motor unit 400. The power supply protruding terminal portion 600 is attached to the ultrasonic transducer moving portion 900, which is connected to the rotary motor portion 400 via the eccentric shaft portion 500, and the ultrasonic transducer portion 300 is located below it so that it can move horizontally in a straight line. The ultrasonic transducer unit 300 is moved linearly by the ultrasonic transducer moving unit 900, and the radius of rotation of the ultrasonic transducer unit 300 can be adjusted by the eccentric shaft unit 500. That is, in another embodiment of the therapeutic ultrasound generator according to the present invention, the radius of movement of the circular focus formed on the plane can be variably adjusted by moving the ultrasound transducer unit 300 bidirectionally in a linear direction on the plane passing through the eccentric shaft unit 500. In another embodiment of the therapeutic ultrasonic wave generating device according to the present invention, the moving radius of the focal point formed in a circular shape on a plane can be adjusted in various ways depending on the size of the treatment area or the therapeutic effect. The present invention applies energy uniformly to the treatment area by moving the ultrasound focus in a plane at a uniform depth within the skin, but by forming the ultrasound focus in a circle with a certain radius at a uniform depth within the skin, energy can be applied uniformly within the radius, improving treatment performance. The present invention makes it easy to adjust the output of ultrasound and further improve the therapeutic effect by rotating the ultrasound transducer unit 300 at an eccentric position on a plane and moving the focus of ultrasound in a circular pattern on the plane, and also increases the versatility of treatment by widening the radius range of the focus movement. In addition, the present invention simplifies the structure for moving the focus of ultrasonic waves generated by the ultrasonic transducer unit 300 in a circular pattern on the same plane, thereby minimizing the load on the motor and reducing manufacturing costs. The present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the gist of the present invention, and it is clear that these modifications are included in the configuration of the present invention.
