Description

Technical Field

[0001] The present invention relates to an ultrasonic generator equipped with a rotating ultrasonic transducer and an ultrasonic treatment handpiece including the same, and particularly to an ultrasonic generator equipped with a rotating ultrasonic transducer that can move the focus of ultrasonic waves in a plane within the skin by moving while rotating the ultrasonic transducer at a constant radius, and an ultrasonic treatment handpiece including the same.

Background Art

[0002] Recently, as eating habits become Westernized, obesity has rapidly increased, becoming the most significant cause harming national health and beauty. To treat this, various diet programs and ultrasonic obesity treatment devices have been developed and widely used.

[0003] The high-intensity focused ultrasound (HIFU) obesity treatment technology was originally used for the purpose of anti-cancer treatment that selectively thermocoagulates tumors in internal organs non-invasively to destroy cancer cells. However, Solta Medical in the United States first developed a device called Liposonix with HIFU for the purpose of treating abdominal obesity in the human body.

[0004] In the process of fat destruction using HIFU (high intensity focused ultrasound), when the focused ultrasonic waves are concentrated at a certain location where fat cells are present, the temperature of the tissue instantaneously rises to 65°C to 100°C, thereby causing the tissue to be destroyed.

[0005] Unlike other dermatological equipment, such as laser and RF high-frequency equipment, the HIFU equipment non-invasively concentrates HIFU energy on a selected part without causing any damage to the surface of the skin, inducing coagulation necrosis of fat. The fat cells necrosed in this way are naturally removed by the repair mechanism of the damaged part in the body.

[0006] A known example of an ultrasonic obesity treatment device is the "High-Intensity Focused Ultrasound Generator for Reducing Subcutaneous Fat Layer," which is registered in Korean Patent No. 10-1365946 (published February 24, 2014).

[0007] The aforementioned "high-intensity focused ultrasound generator for reducing the subcutaneous fat layer" moves the transducer to the desired location in the X and Y axes, and then pivots it around the axes to allow the ultrasound to penetrate into the skin.

[0008] However, the aforementioned "high-intensity focused ultrasound generator for reducing the subcutaneous fat layer" has a problem in that, when ultrasound is delivered by pivot drive, due to the characteristics of pivot drive, the ultrasound is delivered in a curved (arc) shape, causing the energy delivered to the skin to decrease towards the periphery, changing the focal depth, and resulting in an inability to perform uniform treatment.

[0009] To solve these problems, the applicant has proposed a structure in which, in Korean Patent Registration No. 1649899, ​​"ultrasonic generator," the focus of the ultrasound generated by the ultrasound generation unit is moved in a circular motion on the same plane. This structure forms the focus of the ultrasound in a circular shape with a constant radius at a uniform depth within the skin, and applies energy uniformly and evenly within the radius to improve therapeutic performance.

[0010] However, the "ultrasonic generator" in Korean Patent Registration No. 1649899 has a structure in which multiple protruding members, each protruding at a different height, are in contact with the upper surface of the ultrasonic generating unit. This not only limits the reduction in size but also presents a problem in that it restricts the stable movement of the focal point of the ultrasonic waves generated by the ultrasonic transducer unit in a circular motion on the same plane.

[0011] Furthermore, the "ultrasonic generator" registered in Korean Patent No. 1649899 has the problem that, because the ultrasonic generating part is rotated while tilted, the ultrasound is generated at an angle, and the focal point is formed diagonally on the skin. As a result, the intensity of the ultrasound transmitted to the skin, i.e., the output of the ultrasound, is not transmitted uniformly to the skin, and it is difficult to increase the radius of the circle formed on the plane.

[0012] Furthermore, the "ultrasonic generator" registered in Korean Patent No. 1649899 has a structure in which multiple protruding members, each protruding at a different height, are in contact with the upper surface of the ultrasonic generator. Because the ultrasonic generator is rotated while tilted, the structure is complex and manufacturing costs are high. Moreover, there is a problem in that a torsional moment is generated, requiring a large load to rotate the ultrasonic generator.

[0013] Furthermore, Korean Patent Registration No. 10-1365946 (published February 24, 2014) "High-Intensity Focused Ultrasound Generator for Reducing Subcutaneous Fat Layer" and Korean Patent Registration No. 1649899 "Ultrasound Generator" each contain a single ultrasound transducer, which limits the depth to which the ultrasound focal point can reach to a single depth, thus limiting the effectiveness of ultrasound therapy or skin management, and making it difficult to determine the effectiveness of ultrasound therapy or skin management depending on the patient's skin condition. [Overview of the project] [Problems that the invention aims to solve]

[0014] The object of the present invention is to provide an ultrasonic generator equipped with a rotating ultrasonic transducer that can rotate the ultrasonic transducer while moving it at a constant radius, thereby rotating the focal point of the ultrasound within the skin while moving it in a planar direction, and an ultrasonic treatment handpiece including the same.

[0015] Another object of the present invention is to provide an ultrasonic generator equipped with a rotating ultrasonic transducer and an ultrasonic treatment handpiece including the same, which can rotate the ultrasonic transducer moving at a constant radius to prevent twisting of the power supply wires to the ultrasonic transducer.

[0016] Another object of the present invention is to provide an ultrasonic generator equipped with a rotating ultrasonic transducer that can move the focus of the ultrasound in a circular manner at a uniform depth in the skin, thereby allowing the ultrasound to penetrate the skin uniformly and evenly, and an ultrasonic treatment handpiece including the same. [Means for solving the problem]

[0017] To achieve the above objective, one embodiment of an ultrasonic generator equipped with a rotating ultrasonic transducer according to the present invention includes: a cartridge housing portion having a window portion on its lower surface that contacts the skin and through which ultrasonic waves pass; an ultrasonic transducer portion located within the cartridge housing portion that generates ultrasonic waves; a rotating mounting portion on which the ultrasonic transducer portion is rotatably mounted by axial coupling of the transducer rotation shaft, and which rotates within the cartridge housing portion at a predetermined radius to move the ultrasonic transducer portion in a circular motion; and a rotating motor portion that rotates a rotation shaft portion connected to the rotating mounting portion, wherein the ultrasonic transducer portion revolves around the rotation shaft portion and rotates on its own axis around the transducer rotation shaft during its revolving.

[0018] One embodiment of an ultrasonic generator equipped with a rotating ultrasonic transducer according to the present invention may further include a transducer rotation unit that rotates the ultrasonic transducer unit about the transducer rotation axis.

[0019] In the present invention, the transducer rotating section may include a power supply wire section that is electrically connected to the ultrasonic transducer section, supplies electrical power to the ultrasonic transducer section, and controls the operation of the ultrasonic transducer section.

[0020] In the present invention, the ultrasonic transducer unit may be connected to the power supply wire unit and rotate about the transducer rotation axis in a state where the connected portion is positioned facing a certain direction.

[0021] In the present invention, the power supply wire unit may have a telescopic wire or a power cable structure.

[0022] In the present invention, the power supply wire unit may be a spring coil wire portion wound in a spiral shape and elastically telescopic.

[0023] In the present invention, the transducer rotating unit may further include a rod portion for holding a coil that is erected and penetrates inside the spring coil wire portion.

[0024] In the present invention, the rotary mounting portion includes a mounting arm member whose upper end is connected to the rotary shaft portion and whose lower end is connected to the ultrasonic transducer unit by the transducer rotation axis, and the mounting arm member may be disposed obliquely.

[0025] In the present invention, the transducer rotation axis is located at an eccentric position separated from the center of the ultrasonic transducer unit, and the focal point of the ultrasonic wave may move circularly with the distance separated from the transducer rotation axis as the radius by the rotation of the ultrasonic transducer unit.

[0026] In the present invention, the ultrasonic transducer unit may include a plurality of ultrasonic transducers and a transducer mounting body portion on which the plurality of ultrasonic transducers are mounted and are rotatably coupled to the rotary mounting portion about the transducer rotation axis.

[0027] In the present invention, at least one of the plurality of ultrasonic transducers may have a different position where the focal point of the ultrasonic wave reaches.

[0028] In the present invention, the transducer rotating unit may include a transducer rotation motor that rotates the ultrasonic transducer unit.

Advantages of the Invention

[0029] In the present invention, since the ultrasonic transducer can be rotated while being moved at a constant radius to rotate the focal point of the ultrasonic wave in a planar manner within the skin, various treatment effects can be obtained.

[0030] Moreover, in the present invention, since the ultrasonic transducer that moves at a constant radius can be rotated to prevent the twisting of the electric wire that supplies power to the ultrasonic transducer, a stable electric power can be supplied to the ultrasonic transducer unit via the electric wire, and the effect of ensuring the operating stability is achieved.

[0031] Furthermore, in the present invention, the focal point of the ultrasonic wave is moved in a planar manner at a uniform depth within the skin to uniformly and equally apply energy to the treatment site. However, by forming the focal point of the ultrasonic wave in a circular shape having a constant radius at a uniform depth within the skin and uniformly and equally applying energy within the radius, the effect of improving the treatment performance is achieved.

[Modes for carrying out the invention]

[0033] The present invention will be described in more detail below.

[0034] Preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings as follows. Prior to the detailed description of the present invention, terms or words used in this specification and claims as described below should not be construed as being limited to their ordinary or lexicographical meanings. Therefore, the embodiments described herein and the configurations shown in the drawings are merely the most preferred embodiments of the present invention and do not represent the entire technical idea of ​​the present invention, and it should be understood that there are various equivalents and modifications that can substitute for them at the time of filing.

[0035] The present invention will be described in more detail below.

[0036] Preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings as follows. Prior to the detailed description of the present invention, terms or words used in this specification and claims as described below should not be construed as being limited to their ordinary or lexicographical meanings. Therefore, the embodiments described herein and the configurations shown in the drawings are merely the most preferred embodiments of the present invention and do not represent the entire technical idea of ​​the present invention, and it should be understood that there are various equivalents and modifications that can substitute for them at the time of filing.

[0037] Figure 1 is a perspective view showing one embodiment of the ultrasonic treatment handpiece according to the present invention, and Figure 2 is an exploded perspective view showing one embodiment of the ultrasonic treatment handpiece according to the present invention.

[0038] Referring to Figures 1 and 2, the ultrasonic therapy handpiece according to the present invention includes a cartridge housing 200 in which an ultrasonic transducer 300 is located, and a main body housing 100 to which an ultrasonic generator that passes ultrasonic waves through a window 203 located at the bottom of the cartridge housing 200 and irradiates the skin is detachably coupled.

[0039] The ultrasonic therapy handpiece according to the present invention is connected to a control unit 1000 via a handpiece cable body 1100 which includes a power cable and a medium supply line and a medium discharge line for circulating the medium within the cartridge housing 200. The handpiece cable body 1100 and the control unit 1000 can be modified and implemented in various forms of known ultrasonic therapy devices, so a more detailed explanation will be omitted.

[0040] The ultrasonic generator, i.e., the cartridge housing 200, is detachably connected to the main housing 100 and may be replaced after being used a predetermined number of times.

[0041] Furthermore, the ultrasonic generator includes embodiments of an ultrasonic generator equipped with a rotating ultrasonic transducer according to the present invention, which are described in detail below.

[0042] The main body housing 100 is equipped with a cartridge locking device 101 capable of locking and securing the cartridge housing 200. The cartridge locking device 101 is elastically supported by a spring, and its wedge-shaped locking portion engages with a locking groove on the inside of the cartridge housing 200 to fix the connected state of the cartridge housing 200. When pressed, the locking portion disengages from the locking groove, allowing the cartridge housing 200 to be separated.

[0043] Since the cartridge housing 200 can be maintained in a coupled state with the main housing 100 or separated by applying a known, releasable locking structure other than the cartridge locking device 101, a more detailed explanation will be omitted.

[0044] A handle portion 110, which can be grasped by the operator, is located on one side of the main body housing portion 100.

[0045] The handle portion 110 includes a handle connecting portion 111 that is positioned bent on the upper side of the main body housing portion 100, and a handle body 112 that is bent at the handle connecting portion 111 and positioned downward.

[0046] The practitioner can grasp the handle body 112, which bends at the handle connecting portion 111 and extends integrally downward, and easily bring the window portion 203 of the cartridge housing portion 200 into close contact with the skin to perform the procedure.

[0047] The handle portion 110 has a shape that bends upward and then curves downward, and is designed to be gripped by the downward-extending portion, i.e., the handle body 112, minimizing the load applied to the practitioner during treatment, and allowing the window portion 203 of the cartridge housing portion 200 to be easily brought into close contact with the skin during treatment.

[0048] On the other hand, the ultrasonic generating device equipped with a rotating ultrasonic transducer according to the present invention includes a cartridge housing portion 200 having a window portion 203 on its lower surface that comes into contact with the skin and through which ultrasonic waves pass, and an ultrasonic transducer portion 300 located inside the cartridge housing portion 200 that generates ultrasonic waves.

[0049] The window portion 203 is made of a transparent or translucent material that allows ultrasonic waves to pass through, and since it is made of a known material that allows ultrasonic waves to pass through, a more detailed explanation will be omitted.

[0050] The cartridge housing section 200 includes an upper housing section 201 that is detachably connected to the main housing section 100, and a housing sealing cap section 202 that is detachably connected to the lower side of the upper housing section 201.

[0051] A window portion 203 is formed on the lower surface of the housing sealing cap portion 202, with a size that allows for ultrasonic treatment to be performed in contact with the patient's skin.

[0052] The cartridge housing 200 has a sealed internal structure and is filled with an ultrasonic transmission medium.

[0053] The ultrasonic transmission medium is, for example, an insulating liquid, and since the insulating liquid can be modified in various ways in the form of a known insulating liquid that does not conduct electricity, a more detailed explanation will be omitted.

[0054] The ultrasonic transmission medium not only transmits ultrasound waves but also cools the patient's skin through the window portion 203 that comes into contact with the skin.

[0055] A cartridge board section 201a is located at the top of the cartridge housing section 200 to seal the inside of the cartridge housing section 200, and a medium supply protruding pipe section 210 and a medium discharge protruding pipe section 220 for circulating the ultrasonic transmission medium are positioned to protrude from the upper surface of the cartridge board section 201a.

[0056] For example, the rotary motor section 400 includes a rotary shaft section 420 mounted on the upper surface of the rotary mounting section 500, and the rotary shaft section 420 is mounted on the rotation center of the rotary mounting section 500 so as to protrude from the upper surface of the rotary mounting section 500, and has a structure that allows it to be detachably coupled to the rotary motor section 400.

[0057] Inside the cartridge housing 200, a rotatable mounting section 500, on which the ultrasonic transducer section 300 is rotatably mounted, is positioned so that it can move in a circular motion within a predetermined radius by rotating around a rotating shaft section 420 within the cartridge housing 200.

[0058] The rotating shaft portion 420 is positioned upright in the center of the cartridge housing portion 200 inside the cartridge housing portion 200, its lower end is connected to the rotating mounting portion 500 on which the ultrasonic transducer portion 300 is rotatably mounted, and a portion of its upper end is positioned to protrude from the upper surface of the cartridge board portion 201a and is connected to the rotating motor portion 400.

[0059] The rotating motor unit 400 is connected to the rotating shaft unit 420 and transmits rotational force to the rotating shaft unit 420, thereby rotating the rotating mounting unit 500, on which the ultrasonic transducer unit 300 is rotatably mounted, around the rotating shaft unit 420.

[0060] The ultrasonic transducer unit 300 is mounted on the rotary mounting unit 500 at an eccentric position, spaced apart from the rotation center of the rotary mounting unit 500, that is, from the rotation center to which the rotary shaft unit 420 is connected.

[0061] The rotating mounting section 500 may include a mounting arm member 510 that is connected to the center of rotation to which the rotating shaft section 420 is connected, that is, connected to the lower end side of the rotating shaft section 420, and positioned to move in a circular motion by rotating integrally with the rotating shaft section 420.

[0062] The ultrasonic transducer unit 300 is rotatably mounted on the end side of the mounting arm member 510 and rotatably mounted on the transducer rotation shaft 600a that protrudes vertically from the lower end of the mounting arm member 510.

[0063] A bearing is provided between the transducer rotation shaft 600a and the ultrasonic transducer section 300, allowing the ultrasonic transducer section 300 to rotate smoothly around the transducer rotation shaft 600a.

[0064] In summary, the ultrasonic transducer unit 300 is positioned at a distance from the rotation center of the rotating mounting unit 500, but is mounted on the rotating mounting unit 500 so as to be rotatable around the transducer rotation axis 600a, and rotates itself around the transducer rotation axis 600a while moving in a circular motion with a predetermined radius from the rotation center of the rotating mounting unit 500.

[0065] In other words, the ultrasonic transducer unit 300 revolves around the rotating shaft unit 420, and rotates on its own axis around the transducer rotating shaft 600a while revolving.

[0066] Furthermore, one embodiment of an ultrasonic generator equipped with a rotating ultrasonic transducer according to the present invention further includes a transducer rotation unit 600 that rotates the ultrasonic transducer unit 300, which is rotatably mounted on a rotating mounting unit 500, on its own.

[0067] The transducer rotating section 600 is electrically connected to the ultrasonic transducer section 300 and includes a power supply wire section 610 that supplies power to the ultrasonic transducer section 300 and controls the operation of the ultrasonic transducer section 300.

[0068] The power supply wire section 610 is connected to the ultrasonic transducer section 300, and is configured to rotate itself around the transducer rotation axis 600a when the rotating mounting section 500 rotates and the ultrasonic transducer section 300 moves in a circular motion with a predetermined radius.

[0069] The power supply wire section 610 has a sufficient length to remain connected to the ultrasonic transducer section 300 when the ultrasonic transducer section 300 moves in a circular motion with a predetermined radius.

[0070] Furthermore, since the power supply wire section 610 has a retractable wire or power cable structure, the tension of the wire or cable causes the ultrasonic transducer section 300 to rotate, that is, to rotate around the transducer rotation axis 600a.

[0071] In summary, the power supply wire section 610 has a wire or power cable structure that allows for elastic length adjustment, and the tension of the wire or cable causes the ultrasonic transducer section 300 to rotate, that is, to rotate around the transducer rotation axis 600a.

[0072] As an example, the power supply wire section 610 may be a spring coil wire section 611 that is wound in a spiral shape and is elastically expandable and contractible.

[0073] Alternatively, although not shown in the figures, the power supply wire section 610 may have a structure in which the wire or power cable is wound onto an elastically supported winding roll, and after being unwound from the winding roll, it may be wound onto the winding roll again by elastic force.

[0074] The power supply wire section 610 holds the ultrasonic transducer section 300 at the connection point, and when the ultrasonic transducer section 300 moves in a circular motion with a predetermined radius due to the rotation of the rotating mounting section 500, it is configured to rotate on its own around the transducer rotation axis 600a.

[0075] On the other hand, the ultrasonic transducer unit 300 has its lower surface, which emits the generated ultrasonic waves, positioned perpendicular to the window unit 203, that is, parallel to the window unit 203, and emits ultrasonic waves from a direction perpendicular to the window unit 203.

[0076] The ultrasonic transducer unit 300 is advantageous in terms of manufacturing and output measurement because it generates ultrasound perpendicular to the window unit 203 that comes into contact with the skin, and it can generate ultrasound while moving in a circular motion, and since no torsional moment is generated, it can be driven with a relatively small load.

[0077] The rotary motor section 400 is located inside the main body housing section 100, and when the cartridge housing section 200 is coupled to the lower part of the main body housing section 100, the rotary shaft section 420 is connected to the portion of the cartridge housing section 200 that protrudes upward, that is, the portion that protrudes from the upper surface of the cartridge board section 201a.

[0078] As an example, the rotary motor section 400 is located inside the main body housing section 100, and when the cartridge housing section 200 is coupled to the lower part of the main body housing section 100, it is connected to the rotary shaft section 420. Depending on the lifespan of the ultrasonic transducer section 300, replacement costs can be reduced when replacing the cartridge housing section 200.

[0079] Although not shown in the diagram, the rotary motor unit 400 may be mounted in the cartridge housing unit 200 and may be replaced together with the cartridge housing unit 200 when the ultrasonic transducer unit 300 is replaced due to its service life.

[0080] The rotating shaft portion 420 is rotatably positioned so as to protrude from the upper surface of the cartridge board portion 201a.

[0081] The rotating shaft portion 420 is rotatably positioned to penetrate the cartridge board portion 201a and can be implemented using a known sealing structure that seals the rotating shaft; therefore, a more detailed explanation will be omitted.

[0082] The rotating shaft portion 420 includes a connecting shaft portion 421 that protrudes from the upper part of the cartridge board portion 201a, i.e., the upper part of the cartridge housing portion 200, and is connected to the rotating motor portion 400. The shaft of the rotating motor portion 400 is provided with a shaft adapter portion 410 into which the connecting shaft portion 421 is inserted and connected to the connecting shaft portion 421.

[0083] For example, the shaft adapter portion 410 has a shaft insertion portion located on its lower side that is open to allow the connecting shaft portion 421 to be inserted inside. The connecting shaft portion 421 is a shaft having a polygonal cross-section, and the shaft insertion portion is a polygonal insertion groove portion corresponding to the connecting shaft portion 421.

[0084] Inside the main body housing 100, when the cartridge housing 200 is connected, there are supply pipe connection parts (not shown) and discharge pipe connection parts (not shown) that connect the medium supply protruding pipe 210 and the medium discharge protruding pipe 220 to a medium circulation unit (not shown) located inside the control body 1000 that controls the operation of the ultrasonic treatment handpiece.

[0085] The control unit 1000 can be modified in various ways in known ultrasonic therapy devices that include a control unit for controlling the operation of an ultrasonic therapy handpiece and a medium circulation unit for circulating an ultrasonic transmission medium, so a more detailed explanation will be omitted.

[0086] The medium circulation section, although not shown in the figures, is a known cooling water circulation structure that can be modified in various ways and includes a medium storage tank, a medium supply line section connecting the medium storage tank and a supply pipe connection section (not shown), a medium discharge line section connecting the medium storage tank and a discharge pipe connection section (not shown), a valve located in the medium supply line section, and a medium cooling section located in the medium storage tank. Therefore, a more detailed explanation will be omitted.

[0087] The supply pipe connection section (not shown) includes a first protruding pipe insertion section into which the medium supply protruding pipe section 210 is inserted, and the discharge pipe connection section (not shown) includes a second protruding pipe insertion section into which the medium discharge protruding pipe section 220 is inserted.

[0088] For example, the medium supply protruding pipe section 210 is inserted into the first protruding pipe insertion section and connected to the medium supply line section with the flow path open, and the medium discharge protruding pipe section 220 is inserted into the second protruding pipe insertion section and connected to the medium discharge line section with the flow path open.

[0089] The medium supply protruding pipe section 210 and the supply pipe connection section (not shown), and the medium discharge protruding pipe section 220 and the discharge pipe connection section (not shown) can be modified in various ways using a known pipe connection structure that connects two pipes to each other and includes a valve that is opened when the connection is made.

[0090] When the cartridge housing section 200 is connected to the main housing section 100, the connecting shaft section 421 of the rotating shaft section 420 is inserted into the shaft insertion section of the shaft adapter section 410, thereby connecting the rotating shaft section 420 and the shaft of the rotating motor section 400. The medium supply protruding pipe section 210 is inserted into the first protruding pipe insertion section of the supply pipe connection section (not shown) and connected to the medium circulation section of the control body 1000. The medium discharge protruding pipe section 220 is inserted into the second protruding pipe insertion section of the discharge pipe connection section (not shown) and connected to the medium circulation section of the control body 1000.

[0091] Furthermore, the upper surface of the cartridge housing 200, that is, the upper surface of the cartridge board 201a, is provided with a pair of first main power supply terminals 230 for supplying power to the ultrasonic transducer 300. Although not shown, the main body housing 100 is connected to a pair of first main power supply terminals 230, and a second main power supply terminal is located inside, which is connected to the control unit 1000 via a handpiece cable 1100.

[0092] For example, the first main power supply terminal 230 is a protruding terminal that protrudes from the upper surface of the cartridge housing portion 200, that is, from the upper surface of the cartridge board portion 201a, and the second main power supply terminal is an insertable terminal into which the first main power supply terminal 230 can be inserted and connected.

[0093] When the cartridge housing 200 is connected to the main housing 100, a pair of first main power supply terminals 230 are inserted into a pair of second main power supply terminals and connected to each other, and the ultrasonic transducer 300 is connected to the control unit 1000 via the handpiece cable 1100, and the operation can be controlled by receiving power from the control unit 1000.

[0094] On the other hand, Figure 3 is a cross-sectional view showing one embodiment of an ultrasonic generator equipped with a rotating ultrasonic transducer according to the present invention, and Figure 4 is a bottom view showing one embodiment of an ultrasonic generator equipped with a rotating ultrasonic transducer according to the present invention.

[0095] Referring to Figures 3 and 4, one embodiment of an ultrasonic generator equipped with a rotating ultrasonic transducer according to the present invention includes a shaft support plate portion 700 through which a rotating shaft portion 420 is positioned and which supports the rotation of the rotating shaft portion 420, and a plurality of support rod portions 800 which support the position of the shaft support plate portion 700, with one end fixed to the upper surface of the cartridge housing portion 200 and the lower end fixed to the shaft support plate portion 700.

[0096] The rotating shaft portion 420 is rotatably positioned to pass through the shaft support plate portion 700 and rotates stably at the center of the cartridge housing portion 200.

[0097] The shaft support plate portion 700 is fixed within the cartridge housing portion 200 by a plurality of support rod portions 800, and the support rod portions 800 stably support the position of the shaft support plate portion 700.

[0098] The rotating shaft portion 420 protrudes a portion from the lower side of the shaft support plate portion 700 and is connected to the rotating mounting portion 500.

[0099] The mounting arm member 510, which is the rotating mounting section 500, has its upper end connected to the rotating shaft section 420, and the ultrasonic transducer section 300 is rotatably positioned at its lower end.

[0100] The mounting arm member 510 is, for example, a rod-shaped object with a cylindrical or polygonal cross-section, and is positioned at an angle to prevent the power supply wire 610 from getting caught and twisted during circular movement with a predetermined radius.

[0101] The power supply wire section 610 is a spirally wound and elastically expandable spring coil wire section 611, and the transducer rotating section 600 further includes a coil holding rod section 620 that is positioned upright and penetrates the interior of the spring coil wire section 611.

[0102] The coil-holding rod portion 620 guides the spring coil wire portion 611 to be unwound sequentially from its lower end connected to the ultrasonic transducer portion 300 when the spring coil wire portion 611 is pulled and its length increases due to the movement of the ultrasonic transducer portion 300, and guides it to be wound again in the reverse order of how it was unwound when the spring coil wire portion 611 contracts again due to elastic force while extended due to the movement of the ultrasonic transducer portion 300.

[0103] The coil-holding rod portion 620 supports the position of the spring coil wire portion 611 as it is unwound and wound up while the ultrasonic transducer portion 300 moves in a circular motion on a plane, and maintains the coil shape of the spring coil wire portion 611 even when the spring coil wire portion 611 is repeatedly unwound and wound up.

[0104] The ultrasonic transducer unit 300 is connected to the power supply wire unit 610 for power supply and operation control. The ultrasonic transducer unit 300 moves in a circular motion on a plane with a predetermined radius by the rotation of the rotating shaft unit 420, emitting ultrasonic waves, so that the focal point of the emitted ultrasonic waves moves in a circular motion on the plane.

[0105] The ultrasonic transducer section 300 moves in a circular motion on a plane, pulling and unwinding the spring coil wire section 611. The elastic force generated by the spring coil wire section 611 at this time causes it to rotate around the transducer rotation axis 600a, so that the part to which the spring coil wire section 611 is connected always faces a certain direction, thereby preventing twisting of the spring coil wire section 611.

[0106] The ultrasonic transducer unit 300 moves in a circular motion on a plane, with a radius equal to the distance from the rotation center of the rotating mounting unit 500. As a result, the focal points of the ultrasonic waves generated by each ultrasonic transducer unit 300 move in a circular motion on the same plane.

[0107] The ultrasonic transducer unit 300 rotates around the rotation axis 420 so that the window unit 203 and the ultrasonic generating surface are aligned in a direction perpendicular to the window unit 203, that is, with the ultrasonic generating surface positioned horizontally, so that the focal point of the ultrasonic waves generated by the ultrasonic transducer unit 300 moves in a circular shape on the same plane.

[0108] In other words, the ultrasonic generator equipped with a rotating ultrasonic transducer according to the present invention can move the focal point of each ultrasonic wave generated by the ultrasonic transducer section 300 on the same plane with a predetermined radius while positioning it at a uniform depth within the skin, thereby forming a circular movement path on the plane, and further improving therapeutic performance by uniformly and evenly applying energy within the radius.

[0109] On the other hand, Figure 5 is a cross-sectional view showing another embodiment of the ultrasonic generator equipped with a rotating ultrasonic transducer according to the present invention, and Figure 6 is a bottom view showing another embodiment of the ultrasonic generator equipped with a rotating ultrasonic transducer according to the present invention.

[0110] Referring to Figures 5 and 6, the transducer rotation axis 600a, which is the rotation axis of the ultrasonic transducer unit 300, is located at an eccentric position with respect to the center of the ultrasonic transducer unit 300, that is, the focal point of the ultrasonic waves generated by the ultrasonic transducer unit 300. As the ultrasonic focal point moves in a circular motion due to the rotation of the ultrasonic transducer unit 300, the circularly formed ultrasonic focal point can move again on the same plane with a predetermined radius.

[0111] The ultrasonic transducer unit 300 moves in a circular motion on a plane, with a radius equal to the distance from the rotation center of the rotating mounting unit 500, due to the rotation of the rotating mounting unit 500. At this time, the ultrasonic transducer unit 300 is rotated by the transducer rotating unit 600.

[0112] The ultrasonic transducer section 300 moves in a circular motion with a predetermined radius due to the rotation of the rotating mounting section 500, and rotates around the transducer rotation axis 600a due to the elastic force of the spring coil wire section 611. However, since the transducer rotation axis 600a is eccentrically positioned with respect to the focal point of the ultrasound, it moves in a circular motion with a radius equal to the distance eccentrically from the focal point around the transducer rotation axis 600a.

[0113] Furthermore, the transducer rotating section 600 may further include a transducer rotating motor 630 located on the end side of the rotating mounting section 500, which rotates the ultrasonic transducer section 300.

[0114] The transducer rotary motor 630 can operate by receiving an electrical power supply via the power supply wire section 610, or by receiving an electrical power supply via a brush structure.

[0115] The transducer rotation motor 630 rotates the ultrasonic transducer section 300, which efficiently prevents twisting due to the circular movement of the ultrasonic transducer section 300 even with respect to the power supply wire section 610, which does not have an elastic structure. This allows the ultrasonic transducer section 300, which can rotate at an eccentric position around the focal point of the ultrasound, to rotate at a second radius.

[0116] In other words, when the ultrasonic transducer unit 300 moves in a circle of a predetermined radius due to the rotation of the rotating mounting unit 500, the focal point of the ultrasound moves in a circle of a first radius due to the rotation of the rotating mounting unit 500, and also moves in a circle of a second radius that is eccentric with respect to the transducer rotation axis 600a due to the rotation of the ultrasonic transducer unit 300.

[0117] Therefore, in another embodiment of the ultrasonic generator equipped with a rotating ultrasonic transducer according to the present invention, the focal point of the ultrasound can be moved in a circular motion on a plane with a large first radius while simultaneously moving in a circular motion on a plane with a small second radius, thereby ensuring versatility in ultrasonic therapy and enabling appropriate ultrasonic therapy according to the patient.

[0118] Furthermore, Figure 7 is a cross-sectional view showing yet another embodiment of the ultrasonic generator equipped with a rotating ultrasonic transducer according to the present invention, and Figure 8 is a bottom view showing yet another embodiment of the ultrasonic generator equipped with a rotating ultrasonic transducer according to the present invention.

[0119] The ultrasonic transducer unit 300 includes a plurality of ultrasonic transducers 310 and 320, and a transducer mounting body unit 330 to which the plurality of ultrasonic transducers 310 and 320 are mounted and which is rotatably coupled to the rotary mounting unit 500 around the transducer rotation axis 600a. By rotating the transducer mounting body unit 330 around the transducer rotation axis 600a, the plurality of ultrasonic transducers 310 and 320 can be moved in a circular motion with a radius at a distance from the rotation center of the rotary mounting unit 500 by the rotation of the rotary mounting unit 500, while the transducer mounting body unit 330 can be rotated, thereby moving each ultrasonic transducer in a circular motion with a radius at a distance from the transducer rotation axis 600a.

[0120] Multiple ultrasound transducers 310 and 320 can each have a structure that positions the ultrasound focal point at the same location, i.e., at the same depth. Alternatively, at least one of the multiple ultrasound transducers 310 and 320 can have a structure that positions the ultrasound focal point at a different location, i.e., at a different depth. Therefore, there are differences in the depth reached by the ultrasound focal point, allowing for therapeutic effects on the skin at various depths.

[0121] Furthermore, the transducer rotating section 600 may further include a transducer rotating motor 630 located on the end side of the rotating mounting section 500, which rotates the ultrasonic transducer section 300, i.e., the transducer mounting body section 330.

[0122] The transducer rotary motor 630 can operate by receiving an electrical power supply via the power supply wire section 610, or by receiving an electrical power supply via a brush structure.

[0123] The transducer rotation motor 630 rotates the transducer mounting body 330, which efficiently prevents twisting of the ultrasonic transducer section 300 due to circular movement, even for the power supply wire section 610 which does not have an elastic structure. By rotating the transducer mounting body 330 around the transducer rotation axis 600a, multiple ultrasonic transducers 310 and 320, whose centers are spaced apart from the transducer rotation axis 600a, are moved in a circular motion with a radius spaced apart from the transducer rotation axis 600a.

[0124] Multiple ultrasonic transducers 310 and 320 are mounted at eccentric positions on a rotating mounting unit 500, which is rotated by a rotating motor unit 400, and rotate on a plane. As a result, the focal points of the ultrasonic waves generated by the ultrasonic transducer unit 300 move in a circular pattern on the same plane.

[0125] Furthermore, since the centers of the multiple ultrasonic transducers 310 and 320 are positioned spaced apart from the transducer rotation axis 600a, and each has an eccentric structure that is spaced apart from the rotation center, the focal point of the ultrasound emitted from each ultrasonic transducer rotates around the transducer rotation axis 600a and moves in a circular motion.

[0126] In other words, each ultrasonic transducer 310, 320 moves in a circular motion with a radius equal to the distance from the rotation center of the rotating mounting part 500, and also moves in a circular motion with a radius equal to the distance from the transducer rotation axis 600a.

[0127] Furthermore, the focal point of the ultrasonic waves generated by each ultrasonic transducer 310 and 320 moves in a circular pattern with a radius equal to the distance from the rotation center of the rotating mounting unit 500, and also moves in a circular pattern with a radius equal to the distance from the transducer rotation axis 600a.

[0128] More specifically, the ultrasonic transducer section 300 includes a first ultrasonic transducer 310 and a second ultrasonic transducer 320. The transducer mounting body section 330 moves in a circular shape with a radius corresponding to the length of the rotating mounting section 500. The first ultrasonic transducer 310 moves along a circular shape with a radius corresponding to the length of the rotating mounting section 500, and also moves in a circular shape with a radius corresponding to a first distance from the transducer rotation axis 600a. The second ultrasonic transducer 320 moves along a circular shape with a radius corresponding to the length of the rotating mounting section 500, and also moves in a circular shape with a radius corresponding to a second distance from the transducer rotation axis 600a.

[0129] Therefore, the focal point of the first ultrasound emitted from the first ultrasonic transducer 310 moves in a circular motion with a radius equal to the distance from the rotation center of the rotating mounting part 500, and also moves in a circular motion with a radius equal to the first distance from the transducer rotation axis 600a.

[0130] Furthermore, the focal point of the second ultrasound emitted from the second ultrasonic transducer 320 moves in a circular motion with a radius equal to the distance from the rotation center of the rotating mounting unit 500, and also moves in a circular motion with a radius equal to the second distance from the transducer rotation axis 600a.

[0131] Therefore, in another embodiment of the ultrasonic generator equipped with a rotating ultrasonic transducer according to the present invention, the focal point of each ultrasonic wave emitted from a plurality of ultrasonic transducers 310, 320 can be moved in a circular motion on a plane with a large first radius and a small second radius, thereby ensuring diversity in ultrasonic therapy and enabling appropriate ultrasonic therapy according to the patient. Furthermore, if the focal depths of each ultrasonic wave differ from one another, even greater diversity in ultrasonic therapy can be ensured, thereby greatly improving patient satisfaction and effectiveness in treatment.

[0132] This invention allows for the rotation of an ultrasonic transducer while moving it with a constant radius, thereby rotating the focal point of the ultrasound within the skin while moving it in a planar direction, and thus enabling a variety of therapeutic effects.

[0133] Furthermore, the present invention prevents twisting of the power supply wires that provide power to an ultrasonic transducer by rotating the ultrasonic transducer, which moves with a constant radius. This ensures a stable supply of electrical power to the ultrasonic transducer unit 300 via the power supply wires, thereby guaranteeing stable operation.

[0134] Furthermore, while the present invention applies energy uniformly and evenly to the treatment site by moving the ultrasound focal point in a plane at a uniform depth within the skin, the treatment performance can be improved by forming the ultrasound focal point into a circle with a constant radius at a uniform depth within the skin and applying energy uniformly and evenly within that radius.

[0135] The present invention is not limited to the embodiments described above, and can be implemented with various modifications without departing from the spirit of the invention, and it should be made clear that such modifications are included in the configuration of the present invention.
