Description

Technical Field

[0001] The present invention relates to a therapeutic ultrasonic generating device and an ultrasonic therapeutic handpiece including the same, and more particularly, to an invention of a therapeutic ultrasonic generating device and an ultrasonic therapeutic handpiece including the same, which simplifies the structure so that the focus of the ultrasonic wave of the ultrasonic generating part moves in a circle on the same plane and can miniaturize the size of the ultrasonic therapeutic handpiece. Background Art

[0002] Recently, the Westernization of eating habits has led to a rapid increase in the number of obese people, which has become the biggest cause of harm to national health and beauty. For treatment, various weight loss programs and ultrasonic obesity treatment devices have been developed and widely used.

[0003] High-intensity focused ultrasound (HIFU) obesity treatment technology was originally intended to be a non-invasive and selective anti-cancer treatment that destroys cancer cells by causing internal organ tumors to coagulate at high temperatures. However, Solta Medical in the United States has developed a device called Liposonix that uses HIFU for the first time for the purpose of treating abdominal obesity in the human body.

[0004] The process of fat destruction using HIFU (high intensity focused ultrasound) is that if the integrated ultrasound is focused on a specific location of the fat cells, the temperature of the tissue will instantly rise to 65℃~100℃, causing tissue destruction.

[0005] HIFU equipment is different from other dermatological equipment such as laser and RF high-frequency equipment. Without damaging the skin surface, HIFU energy is concentrated on the non-invasive selected part to induce coagulation necrosis of fat. In this way, necrotic fat cells will be naturally removed through the body's damaged part repair mechanism.

[0006] A known ultrasonic obesity treatment device is Korean registered patent No. 10-1365946 (published on February 24, 2014) "High-intensity focused ultrasonic wave generating device for reducing subcutaneous fat layer".

[0007] According to the "high-intensity focused ultrasound generating device for reducing subcutaneous fat layer", after the transducer is moved to the desired location along the X-axis and Y-axis directions, it is pivotally driven around the axis to allow ultrasound to penetrate into the skin.

[0008] However, the problem with the "high-intensity focused ultrasound generating device for reducing the subcutaneous fat layer" is that when ultrasound is provided, due to the characteristics of the pivot drive, the ultrasound is provided in a curved surface (arc), so the closer to the periphery, the smaller the energy provided to the skin, the focal depth is changed, and uniform treatment cannot be performed.

[0009] In order to solve these problems, the applicant proposed the following structure in Korean registered patent No. 1649899 "Therapeutic ultrasonic wave generating device", including a focus rotating moving part that makes the ultrasonic focus of the ultrasonic wave generating part move in a circle on the same plane, so that the focus of the ultrasonic wave is formed into a circle with a certain radius at a uniform depth in the skin, and energy is evenly applied within the radius to improve the therapeutic performance.

[0010] However, the problem with Korean registered patent No. 1649899 "Therapeutic Ultrasonic Wave Generator" is that it has limitations in reducing the size due to the structure in which multiple protruding parts protruding at different heights are in contact with the top of the ultrasonic wave generating part, and it has limitations in stably moving the focus of the ultrasonic wave of the ultrasonic transducer part in a circle on the same plane.

[0011] Furthermore, a problem with Korean registered patent No. 1649899 "Therapeutic Ultrasonic Wave Generator" is that since the ultrasonic wave generator rotates in a tilted state and generates ultrasonic waves in an oblique direction, the focus is actually formed on the skin in an oblique direction. Therefore, the intensity of the ultrasonic wave transmitted to the skin, that is, the output of the ultrasonic wave is difficult to be transmitted to the skin evenly, and it is difficult to increase the radius of the circle formed on the plane.

[0012] Furthermore, the problem with Korean registered patent No. 1649899 "Therapeutic Ultrasonic Generator" is that, due to the use of a structure in which multiple protruding parts protruding at different heights contact the top of the ultrasonic generating part, the ultrasonic generating part rotates in an inclined state, making the structure complicated. Not only does it require a lot of manufacturing costs, but it also generates torque, and a large load is required to rotate the ultrasonic generating part. Summary of the invention

[0015] Another object of the present invention is to provide a therapeutic ultrasonic generating device and an ultrasonic therapeutic head including the same, so that the ultrasonic transducer part can rotate at an eccentric position on the plane, and the focus of the ultrasonic wave can be moved in a circle on the same plane, so that the output of the ultrasonic wave can be easily adjusted, the moving radius of the focus can be increased, and the motor load during driving can be minimized.

[0091] in addition, Figure 3 is a cross-sectional view showing an embodiment of the therapeutic ultrasonic wave generating device of the present invention, Figure 4 It is enlarged to show Figure 3 A cross-sectional view of part A, Figure 5 It is a partially enlarged bottom perspective view showing one embodiment of the therapeutic ultrasonic wave generating device of the present invention.

[0092] Reference below Figures 2 to 5 , an embodiment of the therapeutic ultrasonic wave generating device of the present invention is described in more detail.

[0093] In one embodiment of the therapeutic ultrasonic wave generating device of the present invention, the ultrasonic transducer unit 300 is connected to the rotary motor unit 400 via an eccentric shaft unit 500 eccentric from the center of the main body of the ultrasonic transducer unit 300 .

[0094] When the ultrasonic transducer unit 300 rotates in an eccentric state with the eccentric shaft unit 500 as the center, the focus of the ultrasonic wave moves along a circle having a predetermined radius from the shaft center of the rotary motor unit 400 .

[0095] The ultrasonic transducer unit 300 is connected to the eccentric shaft unit 500 rotated by the rotary motor unit 400 at an eccentric position and rotates on a plane, whereby the focus of the ultrasonic wave generated by the ultrasonic transducer unit 300 moves in a circle on the same plane.

[0096] The ultrasonic transducer section 300 irradiates the window section 203 with ultrasonic waves in a direction perpendicular to the window section 203 .

[0097] The ultrasonic generating surface of the ultrasonic transducer unit 300 is parallel to the window unit 203, and irradiates ultrasonic waves in a direction perpendicular to the window unit 203, rotating around an eccentric shaft unit 500 eccentric from the rotation center of the rotating motor unit 400, so that the focus of the ultrasonic waves moves in a circle on the plane.

[0098] That is, according to the therapeutic ultrasonic wave generating device of the present invention, the focus of the ultrasonic wave is located at a uniform depth in the skin, and is moved in a circle on the same plane with a preset radius, so that the moving path of the focus forms a circle on the plane, and energy can be evenly applied within the moving radius of the focus.

[0099] Furthermore, according to the therapeutic ultrasonic generating device of the present invention, when the ultrasonic generating surface of the ultrasonic transducer portion 300 is aligned with the window portion 203, the ultrasonic transducer portion 300 is rotated around the eccentric shaft portion 500 so that the moving path of the focus forms a circle on the plane, thereby making it easy to adjust the output of the ultrasonic wave, and the moving radius of the focus can be selectively designed to be narrow or wide.

[0100] In addition, according to an embodiment of the therapeutic ultrasonic generating device of the present invention, it also includes: a protruding terminal portion 600 for power supply, which protrudes toward the upper side of the ultrasonic transducer portion 300 to supply power to the ultrasonic transducer portion 300; a substrate portion 700 for power supply, which is located in the box shell portion 200 at a position separated from the upper part of the ultrasonic transducer portion 300 and is connected to the protruding terminal portion 600 for power supply.

[0101] On the lower surface of the power supply substrate 700 , there is a ring-shaped annular electrode pattern 710 to which power is applied by connection with a power cable.

[0102] When the ultrasonic transducer unit 300 rotates around the eccentric shaft unit 500 , the power supply protruding terminal unit 600 moves in a circle with the upper end side connected to the annular electrode pattern 710 , and power is stably supplied to the ultrasonic transducer unit 300 .

[0103] The annular electrode pattern 710 is electrically connected to the first main power supply terminal 230 protruding from the upper surface of the case plate portion 201 a through a power cable via a terminal provided through the power supply substrate portion 700 .

[0104] Therefore, when the main body shell part 100 is combined with the box shell part 200, the annular electrode pattern 710 is connected to each other by inserting a pair of first main power supply terminals 230 into a pair of second main power supply terminals, and is connected to the control body 1000 through the head cable body 1100, receives power from the control body 1000, and stably supplies power to the ultrasonic transducer part 300 through the power supply protruding terminal part 600.

[0105] The power supply protruding terminal portion 600 maintains a state of elastically contacting the annular electrode pattern 710 , and moves in a circle while being stably connected to the annular electrode pattern 710 when the ultrasonic transducer portion 300 rotates around the eccentric shaft portion 500 .

[0106] As an example, the protruding terminal portion 600 for power supply includes: a clamp pin component 610, which is connected to the annular electrode pattern 710 and is electrically connected to the ultrasonic transducer portion 300 through an electric wire; a pin insertion component 620, which is located on the upper surface of the ultrasonic transducer portion 300 and on which the clamp pin component 610 is movable up and down; and a pin supporting spring component 630, which is located in the pin insertion component 620 and elastically supports the clamp pin component 610.

[0111] Furthermore, the medium for ultrasonic transmission is an insulating liquid, and even if the protruding terminal portion 600 for power supply is exposed inside the box shell portion 200, a short circuit will not occur. When the two exposed annular electrode patterns 710, namely the first electrode pattern 711 and the second electrode pattern 712, are connected to the cathode protruding terminal portion 600a and the anode protruding terminal portion 600b, power can be stably supplied to the ultrasonic transducer portion 300.

[0113] The eccentric shaft portion 500 passes through the substrate position fixing plate portion 800 and the power supply substrate portion 700 , and is connected to the upper surface of the ultrasonic transducer portion 300 at an eccentric position.

[0116] The power cable connecting the annular electrode pattern 710 and the first main power supply terminal 230 is arranged through the inside of the plurality of first board fixing parts 810 and the plurality of second board fixing parts 820 so as not to be exposed to the outside.

[0117] Figure 6 is a partial enlarged view showing another embodiment of the therapeutic ultrasonic wave generating device of the present invention, Figure 6 According to other embodiments of the therapeutic ultrasonic wave generating device of the present invention, the ultrasonic transducer moving part 900 is further included, wherein the ultrasonic transducer part 300 is movably located at the lower part and the upper part is connected to the eccentric shaft part 500.

[0118] The ultrasonic transducer moving unit 900 linearly moves the ultrasonic transducer unit 300 in a circumferential direction from the rotation center of the rotary motor unit 400 on the lower surface, thereby adjusting the rotation radius of the ultrasonic transducer unit 300 based on the rotation center of the rotary motor unit 400 .

[0120] The ultrasonic transducer unit 300 linearly moves by the ultrasonic transducer moving unit 900 , and the rotation radius of the eccentric shaft unit 500 is adjusted by the rotation.

[0121] That is, according to other embodiments of the therapeutic ultrasonic wave generating device of the present invention, the ultrasonic transducer unit 300 is bidirectionally moved in a straight line direction on a plane passing through the eccentric shaft unit 500, and the moving radius of the focus formed into a circle on the plane can be variously adjusted.

[0122] According to other embodiments of the therapeutic ultrasonic wave generating device of the present invention, the moving radius of the focus formed in a circular shape on a plane can be variously adjusted according to the size of the treatment site or the treatment effect.

[0123] According to the present invention, the focus of ultrasound waves is moved in a plane at a uniform depth in the skin, and energy is applied uniformly to the treatment site. The focus of ultrasound waves is formed into a circle with a certain radius at a uniform depth in the skin, and energy is applied uniformly within the radius, thereby improving the treatment performance.

[0124] According to the present invention, the ultrasonic transducer part 300 is rotated at an eccentric position on the plane, and the focus of the ultrasonic wave is moved in a circle on the plane, which makes it easy to adjust the output of the ultrasonic wave, can improve the treatment effect, can expand the moving radius range of the focus, and increase the versatility of the treatment.

[0125] Furthermore, according to the present invention, the structure of moving the focus of the ultrasonic wave generated by the ultrasonic transducer unit 300 in a circle on the same plane is simplified, so that the load of the motor is minimized and the manufacturing cost is saved.

[0126] The present invention is not limited to the above-described embodiments, and the present invention can be implemented in various modified forms without departing from the gist of the present invention, which are also included in the configuration of the present invention.
