Referring to the drawings, a skin care device 20 according to an exemplary embodiment of the present invention includes a skin care device 20 using ultrasound, a xenon lamp, a high frequency LED, an IPL, a laser, The procedure can be performed. In one embodiment, the skin beauty treatment device 20 may be a medical device that performs various procedures using focused ultrasound. Here, the focused ultrasound may include both High Intensity Focused Ultrasound (HIFU) and Low Intensity Focused Ultrasound (LIFU).

In one embodiment, the skin-beauty treatment device 20 can perform two or more different procedures. For example, the skin cosmetic treatment device 20 may perform non-invasive face lifting or skin tightening procedures, and reduction or removal of non-invasive subcutaneous fat layers.

The high-intensity focused ultrasound (hereinafter referred to as 'HIFU') may be for focusing the ultrasound at one focus to form a thermal focus point 12. This thermal focus 12 may be a thermal focus at a high temperature of about 60 캜 or more.

Accordingly, the skin cosmetic treatment apparatus 20 may be configured to form the thermal focus 12 on a dermal layer, a fascia layer, or a SMAS layer located approximately 1.5 to 4.5 mm from the surface of the skin to perform face lifting or skin tightening skin tightening procedure or to perform the fat reduction or removal procedure by forming the thermal focus 12 on the subcutaneous fat layer located at about 6.0 mm to 15.0 mm from the skin surface.

The skin care device 20 according to an embodiment of the present invention may include a handpiece 410 and a cartridge set 500 and may further include a cradle 600 . Here, the handpiece assembly 400 including the handpiece 410 and the cartridges 510, 510-1 and 510-2 may be referred to as a handpiece assembly 400. [

At this time, the treatment handpiece 410 is for irradiating the HIFU to the treatment subject, and may be provided in a hand-held form for the convenience of user's operation. For example, the procedure handpiece 410 may be configured to allow a practitioner to conveniently hold the procedure handpiece 410.

In one embodiment, the treatment handpiece 410 may include a display unit 420 for providing information related to the procedure to a practitioner (not shown), and includes an input unit 430 for receiving a predetermined command from a practitioner . Although the display unit 420 and the input unit 430 are illustrated separately in FIG. 1 and the like, the input unit 430 may include a display unit 420 and an input unit 430 ) May be made integral.

The display unit 420 and the input unit 430 may be connected to the control unit 440 illustrated in Figure 3. An instruction of the operator applied to the input unit 430 is transmitted to the controller 440, Can be operated or controlled.

In one embodiment, the power supply unit 460 may be provided inside the procedure handpiece 410. In this case, a separate cable or the like for supplying external power is not required to be connected to the procedure handpiece 410, The convenience of various procedures using the surgical instrument 410 can be improved. The power supply unit 460 may be implemented as a secondary battery such as a lithium ion battery or may be implemented so that the power supply unit 460 may be charged when the procedure handpiece 410 is mounted on the cradle 600 have. Meanwhile, the vent 415 may function to circulate air inside the procedure handpiece 410 to alleviate the overheating phenomenon of the procedure handpiece 410 and the cartridge.

Next, the cartridge set 500 may mean a set composed of a plurality of cartridges. As an example, the cartridge set 500 may include first to third cartridges 510, 510-1 and 510-2 of the same or similar type or condition of operation. Each of the first to third cartridges 510, 510-1 and 510-2 can be detachably attached to the procedure handpiece 410. For example, the functions of the first cartridge 510, the second cartridge 510-1, and the third cartridge 510-2 are divided according to the skin, the obesity state, or the operation site of the subject, Conditions such as the irradiation intensity and the depth may be the same or similar. In this case, the user can replace the old cartridge having a used life with a new cartridge while using the first to third cartridges 510, 510-1 and 510-2.

As described above, the skin beauty treatment device 20 according to the embodiment of the present invention includes the cartridge set 500 composed of the cartridges 510, 510-1, 510-2 having the same treatment type or treatment condition It is possible to replace the cartridge with a new cartridge and attach it to the procedure handpiece 410 so as to purchase the entire skin beauty treatment device 20 when the life of the transducer 514 is reached But can be used continuously as a cartridge replacement method.

As another example, the cartridge set 500 may include first to third cartridges 510, 510-1, and 510-2 that are different from each other in terms of a procedure type or a procedure condition. Each of the first to third cartridges 510, 510-1 and 510-2 can be detachably attached to the procedure handpiece 410. For example, the functions of the first cartridge 510, the second cartridge 510-1, and the third cartridge 510-2 are divided according to the skin, the obesity state, or the operation site of the subject, Conditions such as intensity and depth of irradiation may be different.

More specifically, each of the first to third cartridges 510, 510-1 and 510-2 has a transitional section 514 provided therein so as to have a procedure interval of approximately 40.0 mm to 100.0 mm. . At this time, the transducer 514 may irradiate the HIFU while moving within the range. On the other hand, when the transverse direction moving range of the transducer 514 is less than 40.0 mm, the operation area can be small and the operation time can be extremely long. The transducer 514 is set to irradiate the HIFU to a certain depth, and the subcutaneous fat layer is bent in both directions with respect to the human navel. Therefore, when the transverse direction of the transducer 514 exceeds 100.0 mm , The initial HIFU irradiance depth and the final HIFU irradiance depth for the subcutaneous fat layer may vary. As a result, the risk of HIFU exposure to areas outside the subcutaneous fat layer can be very high. Therefore, it is preferable that the transducer 514 is set so that it can be moved back and forth within a range of approximately 40.0 mm to 100.0 mm, more preferably within a range of 60.0 mm to 80.0 mm. .

As described above, the skin-beauty treatment apparatus 20 according to the embodiment of the present invention includes the cartridge set 500 composed of the cartridges 510, 510-1, 510-2 having different treatment types or treatment conditions A cartridge suitable for the type of treatment or the treatment condition is selected and mounted on the treatment handpiece 410, so that a customized treatment for each patient can be performed.

Herein, the skin care device according to one embodiment of the present invention will be described with reference to a case where a transducer 514 that generates ultrasonic waves or high-intensity focused ultrasonic waves is provided as a treatment unit, but the present invention is not limited thereto. That is, the treatment unit provided in the skin cosmetic treatment apparatus according to an embodiment of the present invention may be a treatment unit provided with a xenon lamp, a high frequency irradiator, an LED illuminator, an IPL irradiator, a laser generator, or the like in addition to an ultrasonic generator, Can be implemented.

Meanwhile, in the skin beauty treatment device 20 according to an embodiment of the present invention, the rotational force outside the first to third cartridges 510, 510-1 and 510-2 is transmitted to the inside of the cartridge, So that the transducer 514 can be moved in a linear direction.

In one embodiment, the first cartridge 510 may include a transducer 514 and a transducer disposed within an area surrounded by the housing 512, (550).

The first rotation part 550 performs a function of receiving a rotation force provided from the outside of the housing 512. In one embodiment, the first rotation part 550 operates in such a manner that rotational force is transmitted from the second rotation part 453 to the first rotation part 550 . The second rotation part 453 may be connected to a driver. In an embodiment, the motor 450 may be used as a driver. As shown in the figure, the second rotation part 453 may be connected to the second rotation part 453 through a motor shaft 452 or the like And may be connected to the motor 450. The motor 450, the motor shaft 452, and the second rotating portion 453 may be provided on the handpiece 410. Referring to FIG. 2, the first cartridge 510 may be coupled to the procedure handpiece 410. At this time, a portion of the first cartridge 510, which is in contact with the procedure handpiece 410, (453) can be located.

The first rotating portion 550 and the second rotating portion 453 are in direct contact with each other and the rotational force is transmitted from the second rotating portion 453 to the first rotating portion 550, Lt; / RTI > Here, the surfaces where the first rotating portion 550 and the second rotating portion 453 are in contact with each other may be referred to as a first surface and a second surface, respectively.

In one embodiment, the first rotating part 550 and the second rotating part 453 may be generally disc-shaped, and the first surface may be provided with concave and convex parts, that is, concave and convex parts. In addition, the second surface may be provided with a concave portion and a convex portion to be symmetrical with respect to the first surface. Accordingly, even when the cartridges can be replaced, the rotational force generated in the procedure handpiece 410 can be accurately transmitted to the cartridges 510, 510-1 and 510-2.

If the ultrasonic wave generated by the ultrasonic wave generator such as the transducer 514 is HIFU, a thermal focus is formed at a specific portion. If the thermal focus is excessively maintained at the same position, . That is, if a thermal focal point is formed in a state in which the ultrasonic wave generating part is not moved a certain distance after the thermal focus is formed in a specific part, the specific point of the human body may be excessively stimulated and pain, bleeding or injury may occur. However, according to the embodiment of the present invention, since the rotational motion of the second rotating part 453 is accurately transmitted to the first rotating part 550, the degree of movement of the ultrasonic wave generating part can be adjusted by adjusting the degree of rotation of the motor 450 Can be precisely controlled. Therefore, the above-described dangerousness and the like due to the overlapping irradiation of the ultrasonic waves at the same position can be remarkably reduced.

Here, as shown in FIG. 4 and the like, the concave portion may have a shape that becomes deeper and wider as it goes from the rotation axis of the first rotation portion 550 to the outer circumference of the first rotation portion 550. The convex portion may be formed in a triangular pyramid shape. The concave portion and the convex portion may be radially arranged around the rotational axis of the first rotating portion 550. The concave portion and the convex portion provided on the second surface of the second rotating portion 453 may also be symmetrical to the concave portion and the convex portion of the first rotating portion 550.

Accordingly, the first rotation part 550 and the second rotation part 453 can be in intimate contact with each other, and as a result, the power loss during the transmission of the rotational force can be reduced. In a state in which the positions of the concave and convex portions of the first rotating portion 550 and the concave and convex portions of the second rotating portion 453 are not arranged so as to correspond to each other, Even if the process of coupling the first cartridge 510 to the procedure handpiece 410 proceeds in a miss-aligned state in which the relative positions of the first and second surfaces are adjusted during the course of the process, The fitting process of the lumbar part and the convex part can be performed naturally. In addition, when the second rotation part 453 starts to rotate, the relative positions of the first and second surfaces are adjusted and coupling between the first rotation part 550 and the second rotation part 453 is automatically performed It is possible. That is, the convex portion of the second surface is inserted into the concave portion of the first surface, and the convex portion of the first surface is inserted into the concave portion of the second surface. Also, even if the second rotation unit is not rotated, the first rotation unit may be rotated so that the irregularities of the first surface and the irregularities of the second surface are interdigitated and positioned correctly. This process is called self-aligned ). As described above, the skin beauty treatment device 20 according to an embodiment of the present invention can easily mount the cartridges 510, 510-1, 510-2 to the procedure handpiece 410, And the second rotation part 453 can be tightly coupled.

The converting unit is provided between the first rotating unit 550 and the transducer 514 and performs a function of converting the rotational motion of the first rotating unit 550 into linear motion and providing the same to the transducer 514. Accordingly, the transducer 514 can be moved in the linear direction within the first cartridge 510. [

In one embodiment, the conversion unit may include a main section for performing rotational motion and a follower for performing linear motion. A groove portion 541H is spirally formed on the surface of a cylindrical cam 541 in the shape of a cylinder to form a ridge by performing rotational motion and a protrusion 532 inserted into the groove portion 541H of the cylindrical cam 541, The conveying member 531 having the guide portion 533 is moved in a linear direction along the guide portion 533 so that the follower can be formed. Although not shown, the projecting portion may be formed in a spiral shape on the surface of the cylindrical cam 541, and the main moving segment and the follower may be combined in such a manner that the groove on which the projecting portion is inserted is provided in the transferring member 531.

The transducer 514 is fixed to the conveying member 531 so that the transducer 514 can be moved in a linear direction together with the conveying member 531 in accordance with the linear movement of the conveying member 531. [ Here, the transducer 514 and the feeding member 531 may be collectively referred to as an ultrasonic wave generating unit.

In one embodiment, one end of the cylindrical cam 541 is connected to the first rotating portion 550. The other end of the cylindrical cam 541 may be rotatably coupled to the housing 512. 3, a groove is formed in the housing 512 and an axial projection 542 is provided at the other end of the cylindrical cam 541 to insert the axial projection 542 into the groove, (541) can be rotatably coupled to the housing (512). Accordingly, when the first rotation part 550 receives rotational force from the second rotation part 453 and performs rotational motion, the cylindrical cam 541 can also perform rotational motion.

In one embodiment, the rotational axis of the cylindrical cam 541 and the rotational axis of the first rotational part 550 may be positioned in a straight line. Also, the rotation axis of the first rotation part 550 and the rotation axis of the second rotation part 453 may be positioned on a straight line. Accordingly, the rotational force of the motor can be efficiently transmitted to the cylindrical cam 541, but occupies a minimum space, which is advantageous for downsizing.

In one embodiment, the groove portion 541H provided on the surface of the cylindrical cam 541 may be formed to proceed in only one direction. In this case, the conveying member 531 and the transducer 514 can perform the forward movement or the backward movement in accordance with the rotation direction of the cylindrical cam 541. For example, when the cylindrical cam 541 is rotated in the clockwise direction, the feeding member 531 and the transducer 514 are advanced. When the cylindrical cam 541 is rotated counterclockwise, the feeding member 531 and the transducer 514 ) Can go backwards.

A groove portion 541H provided on the surface of the cylindrical cam 541 starts from one side of the cylindrical cam 541 and returns to one end of the cylindrical cam 541 via the other side of the cylindrical cam 541 It can also be a circle of one wheel. In this case, the conveying member 531 and the transducer 514 advance along the guide portion 533 while the cylindrical cam 541 rotates 360 degrees, and then perform a linear movement in which the return is made to the original position, that is, a so- can do. At this time, the rotational speed of the cylindrical cam 541 may be adjusted in consideration of the linear reciprocating speed of the transducer 514, the rotational speed of the motor 450 may be adjusted, And a gear (not shown) or the like between the gear 453 and the output shaft 453.

In one embodiment, a transmissive member may be provided in the direction in which the ultrasonic waves generated in the transducer 514 of the first cartridge 510 pass. At this time, the transmission member may be a first window 512w made of a material capable of smoothly transmitting ultrasonic waves.

In another embodiment, a protective cap 570 coupled to the exterior of the first cartridge 510 may be provided. Here, in the protective cap 570, a second window 571 made of a material capable of smoothly transmitting ultrasonic waves may be provided in the direction in which the ultrasonic waves pass.

The protection cap 570 can prevent the first window 512w from being damaged or contaminated. That is, if the first window 512w is damaged, the first cartridge 510 must be repaired or discarded. However, if the second window 571 of the protection cap 570 is damaged, only the protection cap 570 is replaced So that the life of the cartridge can be prolonged.

Further, by varying the thickness of the protective cap 570, the irradiation depth of the ultrasonic waves can be adjusted. That is, in the case of using the protective cap 570 which is thicker than in the case of using the thin protective cap 570, the depth at which the thermal focus is generated can be brought close to the skin surface.

Meanwhile, the empty space inside the first cartridge 510 can be filled with the fluid L. The fluid L serves as a kind of medium for smoothly transmitting the ultrasonic waves generated from the transducer 514 to the outside of the first cartridge 510. Further, the fluid L may perform a function of cooling the transducer 514. For example, the transducer 514 may generate an exothermic phenomenon in the process of generating ultrasonic waves, and the exothermic phenomenon may be mitigated by the fluid.

Therefore, at least the area from the transmitting member of the first cartridge 510 to the transducer 514 needs to be filled with the above-described fluid L. [ In addition, while the first cartridge 510 is being coupled to the procedure handpiece 410 and is being contacted with the body of the subject, the transmission member of the first cartridge 510 may not always be oriented vertically downward have. Therefore, it is preferable to determine the filling amount of the fluid L in consideration of the inclination range of the direction in which the transducer 514 is directed during the procedure. Of course, it is also possible to fill the empty space inside the first cartridge 510 with the above-mentioned fluid L filled.

Meanwhile, when the fluid L is filled in the first cartridge 510, the fluid leakage period or the like of the fluid L may vary depending on the degree of airtightness in the first cartridge 510. For example, when the degree of sealing is low, the fluid L in the first cartridge 510 can be reduced as time elapses. In this case, there may arise a problem that the fluid L needs to be replenished or the first cartridge 510 itself needs to be replaced. However, in the skin beauty treatment device 20 according to the embodiment of the present invention, the first rotation part 550 provided inside the cartridge is supplied with rotational force from the second rotation part 453 provided outside the cartridge, The degree of loss of the fluid L can be reduced since the received torque can be converted through the conversion unit and the transducer 514 can be linearly or linearly reciprocated.

Meanwhile, the housing 512 may include a plurality of frames. 3 and 4, the first frame 521 and the second frame 522 may be provided between the first rotation part 550 and one end of the cylindrical cam 541 in one embodiment. In addition, a third frame 523 may be provided on the other end side of the cylindrical cam 541.

A second axial projection 542b is provided at one end of the cylindrical cam 541 and is rotatably inserted into the first frame 521. A third axial projection 542a is provided at the other end of the cylindrical cam 541 So that the cylindrical cam 541 can be supported by being pivotally inserted into the third frame 523. [ Both ends of the guide portion 533 may be inserted into the first frame 521 and the third frame 523, respectively.

In one embodiment, a part of the first rotation part 550 may be rotatably inserted into the second frame 522. [ Here, a portion inserted into the second frame 522 may be referred to as a first axial projection 551. The first rotating part 550 is connected to the cylindrical cam 541 via the first shaft protrusion 551 and the second shaft protrusion 542b so that the cylindrical cam 541 rotates along with the rotation of the first rotating part 550, Can be rotated. On the other hand, between the second shaft projection 542b and the first frame 521, between the first frame 521 and the second frame 521, between the second frame 522 and the first shaft projection 551, The member 552 may be provided to minimize the leakage of the fluid L described above.

3, the fourth frame 524 may be provided above the cylindrical cam 541. The fourth frame 524 may be provided in the first cartridge 510, And the circuit board 590 can be positioned above the fourth frame 524. [ That is, the area enclosed by the first through fourth frames 521, 522, 523, and 524 and the area where the circuit board 590 is located can be separated within the first cartridge 510, 590 can be disposed inside the first cartridge 510 without being in contact with the above-described fluid L. [ The circuit board 590 may be inserted into the socket 470 or the like provided in the procedure handpiece 410 in the process of coupling the first cartridge 510 to the procedure handpiece 410, The socket 470 may be connected to the control unit 440 or the like.
