Description

TECHNICAL FIELD

[0001] The present application relates to a therapeutic ultrasound generating device and an ultrasound treatment handpiece including the same, and more particularly, to a therapeutic ultrasound generating device and an ultrasound treatment handpiece including the same, which can reduce the size of an ultrasound treatment handpiece by simplifying a structure in which a focal point of ultrasound generated by an ultrasound generating portion moves in a circular shape on the same plane. BACKGROUND

[0002] Recently, as eating habits are westernized, obesity is rapidly increasing, which has become a major cause of damage to the health and image of the nation, and in order to treat obesity, various slimming programs and ultrasound obesity treatment devices have emerged and are widely used.

[0003] High Intensity Focused Ultrasound (HIFU) obesity treatment technology was initially used for anti-cancer treatment for selectively hyperthermally coagulating cysts of internal organs in a non-invasive form to destroy cancer cells, but Solta Medical first developed a Liposonix device installed with HIFU for the purpose of treating abdominal obesity.

[0004] The process of destroying fat using HIFU is to destroy tissue when the temperature of the tissue instantaneously rises to 65 to 100°C when ultrasound is directly focused on a certain position of fat cells.

[0005] The HIFU device, unlike other dermatological devices such as laser and RF high frequency devices, does not cause damage to the skin surface, and focuses HIFU energy on a selected site in a non-invasive form to induce coagulation necrosis of fat. The necrotic fat cells are naturally removed by the body's own damage recovery mechanism.

[0006] A known ultrasound obesity treatment device is Korean Patent No. 10-1365946 (published on February 24, 2014) "High Intensity Focused Ultrasound Generating Device for Reducing Subcutaneous Fat Layer".

[0007] The "High Intensity Focused Ultrasound Generating Device for Reducing Subcutaneous Fat Layer" pivots around the shaft by moving the transducer to an arbitrary position in the X-axis and Y-axis directions, thereby allowing ultrasound to penetrate into the inside of the skin.

[0008] However, the 'high intensity focused ultrasound generating device for reducing subcutaneous fat layer' provides the ultrasound wave in a curved surface (circular arc) shape based on the pivoting characteristics, and thus the energy provided to the skin is less as it is closer to the periphery, and the focal point depth is changed, thereby having a problem of uneven treatment.

[0009] To solve the above problems, the applicant proposed a structure in Korean Patent No. 1649899 'ultrasonic wave generating device for treatment' which includes a focal point rotating movement part that moves the focal point of the ultrasound generated by the ultrasound generating part in a circular shape on the same plane, and the movement part forms a circle having a certain radius at a certain depth in the skin by moving the focal point of the ultrasound, and uniformly applies energy within the radius, thereby improving the treatment effect.

[0010] However, Korean Patent No. 1649899 'ultrasonic wave generating device for treatment' is a structure in which a plurality of protruding parts protruding at different heights are in contact with the upper surface of the ultrasound generating part, but the device has limitations in reducing the size and stably moving the focal point of the ultrasound generated by the ultrasound transducer in a circular shape on the same plane. SUMMARY

DETAILED DESCRIPTION

[0047] Hereinafter, the present application will be described in further detail.

[0048] The preferred embodiments of the present application will be described in detail with reference to the accompanying drawings. Before the present application is disclosed and described in detail below, it is to be understood that the application described herein and defined by the claims and their equivalents will not be limited to the terminology or wordings used in the specification. Therefore, the embodiments described in the present specification and the components illustrated in the drawings are merely the best preferred embodiments of the present application and do not represent all technical ideas of the present application. Accordingly, various equivalents and modifications of the present application, which can be substituted for the embodiments described in the present specification and the components illustrated in the drawings, are possible.

[0049] Figure 1 is a perspective view of a handpiece for ultrasonic treatment according to an embodiment of the present application. Figure 2 is an exploded perspective view of a handpiece for ultrasonic treatment according to an embodiment of the present application. Figure 3 is a sectional view of an ultrasonic treatment device according to an embodiment of the present application.

[0050] ReferenceFigures 1 to 2 The handpiece for ultrasonic treatment according to the present application includes a cartridge housing portion 200 in which an ultrasonic transducer 300 is arranged inside, and a main body housing portion 100 to which the cartridge housing portion 200 is detachably coupled.

[0051] It is noted that the handpiece for ultrasonic treatment according to the present application is connected to the control main body 1000 through a handpiece cable 1100 including a power cable, a medium supply line and a medium discharge line for circulating a medium inside the cartridge housing portion 200, and the handpiece cable and the control main body can be variously modified and implemented as known examples in known ultrasonic treatment apparatuses, the detailed description of which is omitted herein.

[0052] The cartridge lock 101 is located in the main body housing portion 100, and is used to catch and fix the cartridge housing portion 200. The cartridge lock 101 is elastically supported by a spring, and a wedge-shaped stopper is caught in a stopper groove located inside the cartridge housing, thereby fixing the coupling state of the cartridge housing portion 200. When pressed, the stopper is released from the stopper groove, thereby enabling the cartridge housing portion 200 to be separated.

[0053] It is noted that the cartridge housing portion 200 can maintain the coupled state with the main body housing portion 100 or be separated by using a known releasable locking structure other than the cartridge lock 101, the detailed description of which is omitted herein.

[0054] The handle portion 110 is located at one side of the main body housing portion 100, and can be held by a practitioner with a hand.

[0055] The handle portion 110 includes a handle coupling portion 111 which is curvedly formed toward the upper side of the main body housing portion 100, and a handle body 112 which is formed in an arc from the handle coupling portion 111 and is arranged downward.

[0056] The handle body 112 is formed in an arc from the handle coupling portion 111 and is integrally extended downward, so that the practitioner can easily perform treatment after holding the handle body 112 with a hand and easily attaching the window portion 203 of the cartridge housing portion 200 to the skin.

[0057] The handle portion 110 is designed to have a shape curved toward the upper side and extended downward in an arc, so as to hold the portion extended downward, i.e., the handle body 112, thereby minimizing the load received by the practitioner during treatment, and enabling the window portion 203 of the cartridge housing portion 200 to be easily attached to the skin for treatment.

[0058] Further, the therapeutic ultrasound wave generating apparatus according to the present application includes a case housing portion 200 having a window portion 203 for transmitting ultrasound waves formed in a lower portion thereof, and an ultrasound wave transducer 300 positioned inside the case housing portion 200 and generating ultrasound waves toward a lower portion side.

[0059] Note that the window portion 203 is made of a transparent or translucent material that can transmit ultrasound waves, i.e., a known material that can transmit ultrasound waves, and thus detailed description thereof is omitted.

[0060] The case housing portion 200 includes an upper housing portion 201 that is detachably coupled to the body housing portion 100, and a tapered housing portion 202 positioned on a lower portion side of the upper housing portion 201 and having a tapered shape in which a diameter gradually decreases toward a lower portion side.

[0061] The case housing portion 200 includes the cylindrical upper housing portion 201 and the tapered tapered housing portion 202 having a tapered shape in which a diameter gradually decreases toward a lower portion side, thereby being able to sufficiently secure a space for disposing a driving portion that rotates the ultrasound wave transducer 300 inside, and being able to smoothly contact a very small portion by reducing an area of a lower surface of the tapered housing portion 202 that contacts the skin.

[0062] The window portion 203 is positioned on a lower surface of the tapered housing portion, and has a size that contacts a very small portion of the patient's skin such as an eye fundus and performs an ultrasound wave treatment.

[0063] The inside of the case housing portion 200 has a closed structure, and is filled with an ultrasound wave transmission medium.

[0064] Note that, as an example, the ultrasound wave transmission medium can be water, and various known ultrasound wave transmission media can be used in addition thereto.

[0065] The ultrasound wave transmission medium not only has a function of transmitting ultrasound waves but also has a function of cooling the patient's skin through the window portion 203 that contacts the skin.

[0066] A medium supply protruding pipe portion 210 and a medium discharge protruding pipe portion 220 for circulating the ultrasound wave transmission medium protrude on an upper surface of the case housing portion 200.

[0067] Further, an inclined block portion 400 having an inclined surface on a lower surface thereof is positioned inside the case housing portion 200 and is rotated based on a rotation motor 500.

[0068] The inclined block portion 400 has a block-shaped rotation shaft portion 410 protruding thereon, and the block-shaped rotation shaft portion 410 is detachably connected to a shaft of the rotation motor 500 on an upper portion thereof.

[0069] The rotary motor 500 is located inside the body housing portion 100, and the block-shaped rotary shaft portion 410 is arranged so as to be exposed on the upper surface thereof or protrude from the upper portion of the cartridge housing portion 200 so as to be connectable to the rotary motor 500 inside the body housing portion 100.

[0070] Note that the block-shaped rotary shaft portion 410 is rotatably located on the upper surface of the cartridge housing portion, and a known sealing structure capable of sealing the rotary shaft can be employed, and detailed description thereof is omitted herein.

[0071] The block-shaped rotary shaft portion 410 has a connecting shaft portion 411 protruding toward the upper surface of the cartridge housing portion 200, and the shaft of the rotary motor 500 has a shaft adapter 510 that is connected to the block-shaped rotary shaft portion 410 by inserting the connecting shaft portion 411 inside the shaft adapter 510.

[0072] The shaft insertion portion is located in the shaft adapter 510, and the shaft insertion portion is open toward the lower portion side so as to allow the connecting shaft portion 411 to be inserted inside the shaft insertion portion, and the connecting shaft portion 411 is a shaft having a polygonal cross section, and as an example, the shaft insertion portion is an insertion groove portion having a polygonal shape corresponding to the connecting shaft portion 411.

[0073] The supply pipe connecting portion 120 and the discharge pipe connecting portion 130 are located inside the body housing portion 100, and when the cartridge housing portion 200 is combined, the medium supply protruding pipe portion 210 and the medium discharge protruding pipe portion 220 are connected to a medium circulation portion (not shown) located inside a control body 1000 for controlling the operation of the ultrasonic treatment handpiece.

[0074] Note that the control body 1000 can be variously modified and implemented in a known ultrasonic treatment device including a control portion for controlling the operation of the ultrasonic treatment handpiece and a medium circulation portion for circulating the medium for ultrasonic wave transmission, and detailed description thereof is omitted herein.

[0075] Note that although not shown, the medium circulation portion can be variously modified and implemented as a known cooling water circulation structure including a medium storage tank, a medium supply line portion for connecting the medium storage tank to the supply pipe connecting portion 120, a medium discharge line portion for connecting the medium storage tank to the discharge pipe connecting portion 130, a gate valve located in the medium supply line, a medium cooling portion located in the medium storage tank, and the like, and detailed description thereof is omitted herein.

[0076] The supply pipe connecting portion 120 has a first protruding pipe insertion portion for inserting the medium supply protruding pipe portion 210, and the discharge pipe connecting portion 130 has a second protruding pipe insertion portion for inserting the medium supply protruding pipe portion 210.

[0077] As an example, the medium supply protruding tube portion 210 is inserted into the inner side of the first protruding tube insertion portion, thereby opening the flow path and connecting to the medium supply line portion. The medium discharge protruding tube portion 220 is inserted into the inner side of the second protruding tube insertion portion, thereby opening the flow path and connecting to the medium discharge line portion.

[0078] It should be noted that the protruding tube portion 210 for medium supply and the supply pipe connecting portion 120; the protruding tube portion 220 for medium discharge and the discharge pipe connecting portion 130 can be variously deformed and implemented as a known pipe connection structure, which includes a gate valve for connecting two pipes and is open when connected.

[0079] In addition, the therapeutic ultrasonic generating device according to the present invention also includes a temperature sensing sensor part 230 for sensing the temperature of the ultrasonic transmission medium in the box outer shell 200, and the temperature sensing sensor part includes a first sensor connection terminal part 231 protruding from the upper surface of the box outer shell 200 and used to connect to the control body 1000.

[0080] The second sensor connection terminal 140 is located inside the main housing 100 and connects the temperature sensing sensor 230 to the control unit 1000 by connecting to the first sensor connection terminal 231. The terminal insertion portion is located in the second sensor connection terminal 140 and is inserted into the terminal insertion portion.

[0081] As an example, the first sensor connection terminal portion 231 is inserted into the inner side of the terminal insertion portion and is connected to the control portion of the control body 1000 through the second sensor connection terminal portion 140 .

[0082] When the cartridge housing 200 is coupled to the main body housing 100, the connecting shaft portion 411 of the block-shaped rotating shaft portion 410 is inserted into the shaft insertion portion of the shaft adapter 510, thereby connecting the block-shaped rotating shaft portion 410 to the shaft of the rotating motor. The medium supply protruding tube portion 210 is inserted into the first protruding tube insertion portion of the supply tube connection portion 120 and connected to the medium circulation portion of the control body 1000. The medium discharge protruding tube portion 220 is inserted into the second protruding tube insertion portion of the discharge tube connection portion 130 and connected to the medium circulation portion of the control body 1000. Furthermore, the temperature sensing sensor portion 230 is connected to the control unit of the control body 1000 by inserting the first sensor connection terminal portion 231 into the interior of the second sensor connection terminal portion 140.

[0083] In addition, the tilting block portion 400 has a block-shaped rotating shaft portion 410 protruding from the center thereof, so that it is rotatably located inside the box shell portion 200, and an inclined surface is arranged on the bottom.

[0084] The inclined block 400 supports the upper surface of the ultrasonic transducer 300 with the inclined surface of the lower surface portion, thereby maintaining the inclined state of the ultrasonic transducer 300.

[0085] The spherical joint portion 420 protrudes at the center of the inclined block 400, and the ultrasonic transducer 300 is rotatably coupled to the spherical joint portion 420.

[0086] The spherical joint portion 420 includes a spherical body 421 rotatably inserted into the upper side of the ultrasonic transducer 300, and a spherical support shaft 422 protruding from the upper portion of the spherical body 421 and connected to the inclined block 400.

[0087] The upper end of the spherical support shaft 422 is fixed to the center of the inclined block 400, and the ultrasonic transducer 300 is continuously inclined in all directions by 360 degrees based on the rotation of the inclined block 400 with the spherical body 421 as the center.

[0088] A plurality of support ball members 430 protrude from the lower surface portion of the inclined block 400, and support the upper surface of the ultrasonic transducer 300 while rotating. A portion of the support ball members 430 is rotatably inserted into the inside of the inclined block 400, and the remaining portion protrudes and supports the upper surface of the ultrasonic transducer 300.

[0089] The plurality of support ball members 430 protrude at the same height toward the lower surface portion of the inclined block 400, and the ultrasonic transducer 300 is inclined at the same angle as the inclined surface. In the inclined state of the ultrasonic transducer 300, all of the support ball members 430 are in contact with and support the upper surface of the ultrasonic transducer 300.

[0090] The ultrasonic transducer 300 is coupled to the spherical body 421, and is supported and inclined in a state in which the upper surface thereof is in contact with the plurality of support ball members 430.

[0091] The plurality of support ball members 430 are arranged at a distance from the center of the inclined block 400 and at the same pitch in the circumferential direction, i.e., radially from the center of the inclined block 400, thereby stably supporting the upper surface of the ultrasonic transducer 300 that is continuously inclined in all directions by 360 degrees.

[0092] If the inclined block 400 is rotated by the rotation motor 500, the ultrasonic transducer 300 is continuously inclined in all directions by 360 degrees based on the rotated inclined block 400.

[0093] In addition, the therapeutic ultrasonic wave generating apparatus according to an embodiment of the present application can miniaturize the structure for allowing the ultrasonic transducer 300 to continuously tilt in 360 degrees in all directions by the tilt block 400 and the support ball member 430 formed on the lower surface of the tilt block 400.

[0094] The therapeutic ultrasonic wave generating apparatus according to an embodiment of the present application can further include a torsion bar member 600 having one end connected to the ultrasonic transducer 300 and the other end connected to the case housing 200.

[0095] The torsion bar member 600 can absorb the vibration generated when the ultrasonic transducer 300 continuously tilts in 360 degrees in all directions, thereby securing the operational stability of the ultrasonic transducer 300.

[0096] Since the torsion bar member 600 absorbs the vibration generated when the ultrasonic transducer 300 continuously tilts in 360 degrees in all directions, the operational stability of the ultrasonic transducer 300 can be secured even when the structure for allowing the ultrasonic transducer 300 to continuously tilt in 360 degrees in all directions is miniaturized.

[0097] If the structure is miniaturized, the radius of the ultrasonic transducer 300 continuously tilting in 360 degrees in all directions becomes small, and the ultrasonic transducer 300 is frequently subjected to impact at a short cycle, thereby generating vibration. The torsion bar member 600 absorbs the impact generated when the ultrasonic transducer 300 continuously tilts in 360 degrees in all directions at a short radius by torsional elasticity, and thus the ultrasonic transducer 300 can stably move when continuously tilting in 360 degrees in all directions, so that the focal point of the ultrasonic wave is circular on the same plane.

[0098] The torsion bar member 600 includes a first mounting portion 610 mounted on the ultrasonic transducer 300, a second mounting portion 620 mounted on the inner side surface of the case housing 200, and a torsion spring portion 630 having both end portions connected to the first mounting portion 610 and the second mounting portion 620, respectively.

[0099] The torsion spring portion 630 is formed to have at least one of a meandering portion or a bending portion, thereby absorbing the impact by torsional elasticity.

[0100] As an example, the torsion spring portion 630 can be formed in an S shape, a C shape, or the like, and have a length capable of absorbing the impact generated when the ultrasonic transducer 300 continuously tilts in 360 degrees in all directions at the same angle with reference to the rotational center axis direction.

[0101] The torsion bar member 600 can be provided in plural, and as an example, a pair of the torsion bar members 600 can be formed on opposite sides of the ultrasonic transducer 300.

[0102] The torsion bar member 600 is provided in a pair of opposite positions, thereby further ensuring the stability of the operation of the ultrasonic transducer 300.

[0103] Figure 4 is a working example of the therapeutic ultrasonic generating apparatus according to the present application. Referring to Figure 3 and Figure 4 The ultrasonic transducer 300 is in a rotatably coupled state with the spherical body 421 of the ball joint, contacts and is supported by the plurality of support ball members 430 protruding from the inclined surface of the inclined block portion 400, and is inclined at the same angle as the inclination of the inclined surface.

[0104] In this state, if the inclined block portion 400 is rotated based on the rotary motor 500, the ultrasonic transducer 300 is continuously inclined in 360 degrees in all directions with the spherical body 421 as the center, and at this time, the focal point of the ultrasonic waves generated by the ultrasonic transducer 300 moves in a circular shape on the same plane.

[0105] Further, the torsion bar member 600 elastically absorbs the vibration generated when the ultrasonic transducer 300 is continuously inclined in 360 degrees in all directions by being twisted, thereby enabling the focal point of the ultrasonic waves to move in a circular shape and stably on the same plane.

[0106] That is, the ultrasonic transducer 300 is continuously inclined in 360 degrees in all directions with the spherical body 421 as the center, thereby enabling the focal point to stably move in a circular shape on the same plane.

[0107] The therapeutic ultrasonic generating apparatus according to the present application enables the focal point of the ultrasonic waves to form a circle having a certain radius at the same depth inside the skin, and further enables energy to be uniformly applied within the radius, thereby improving the treatment effect.

[0111] On the contrary, as shown in (b) of FIG. 1, the ultrasound transducer 300 of the embodiment of the present application irradiates ultrasound waves to the skin in a tilted state, and the focal point C is formed in the skin at the reference depth M in a tilted state, and when compared with the comparative example of the present application shown in (a) of FIG. 1, the height of the focal point is reduced, and the focal point is more concentrated at the reference depth M, so that a converging effect is generated. Figure 5 Figure 5 When compared with the comparative example of the present application shown in (a) of FIG. 1, the height of the focal point is reduced, and the focal point is more concentrated at the reference depth M, so that a converging effect is generated.

[0112] That is, the therapeutic ultrasound generating apparatus according to the present application can greatly improve the skin treatment effect by the focal point converging effect by making the ultrasound transducer 300 continuously tilt in 360 degrees in all directions, making the ultrasound focal point C form a circle in a tilted state, and moving on the same plane, so that the focal point is more concentrated at the reference depth M.
