Referring to the drawings, the ultrasound generating device 20 according to an embodiment of the present invention may be a medical device that performs various procedures using High Intensity Focused Ultrasound (HIFU).

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

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

Thus, the ultrasound generating device 20 is configured to form the thermal lesions 12 in the dermal layer, fascia layer, or SMAS layer located at about 1.5 mm to 4.5 mm from the surface of the skin to perform face lifting or skin tightening tightening procedure or to perform the fat reduction or removal procedure by forming the thermal lesion 12 on the subcutaneous fat layer located approximately 6.0 mm to 15.0 mm from the skin surface.

The ultrasound generating apparatus 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 cartridge 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 control unit 440 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 4. The operator's command applied to the input unit 430 is transmitted to the controller 440, 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 ventilation hole 411 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 ultrasound generating device 20 according to the embodiment of the present invention is provided with the cartridge set 500 composed of the cartridges 510, 510-1, 510-2 having the same procedure type or procedure condition The cartridge is replaced with a new cartridge and mounted on the procedure handpiece 410 so that the entirety of the ultrasonic generator 20 is not newly purchased when the life of the transducer 514 is reached, It can be used continuously as a 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, and more preferably, within a range of 60.0 mm to 80.0 mm. It can be advantageous to shorten.

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

Meanwhile, in the ultrasonic generator 20 according to the embodiment of the present invention, the rotational force of the outside of the first to third cartridges 510, 510-1 and 510-2 is transmitted to the inside of the cartridge, The transducer 514 can be moved in a linear direction.

In one embodiment, the first cartridge 510 may include a rotational force applying unit 550, a transducing unit, and a transducer 514 provided within an area surrounded by the housing 512.

The rotational force applying unit 550 performs a function of receiving a rotational force provided from the outside of the housing 512. For example, a rotational force may be transmitted from the outer rotating portion 453, which performs rotational motion outside the housing 512, to the rotational force applying portion 550. Here, the rotation force applying unit 550 and the outer rotation unit 453 are not in direct contact with each other, but are disposed to face each other with the housing 512 interposed therebetween. The rotational force application unit 550 and the outer rotation unit 453 may be connected to each other by a magnetic force. For this purpose, the torque application portion 550 and the outer rotation portion 453 may be made of a magnetic material or may include a magnetic material. The area between the rotational force application part 550 and the outer rotation part 453 of the housing 512 is made of a nonmagnetic material so that the reduction of the magnetic coupling force between the rotation force application part 550 and the outer rotation part 453 is minimized . Of course, the entire housing 512 may be made of a nonmagnetic material, but it may be made of a magnetic material if it is not in the region between the rotational force applying portion 550 and the outer rotational portion 453.

In one embodiment, the rotational force applying unit 550 and the outer rotating unit 453 may be generally disc-shaped. This maximizes the magnetic coupling force between the rotational force applying unit 550 and the outer rotation unit 453 while occupying a minimum space and minimizing the frictional force.

The housing 512 is provided with a concave portion so that the rotational force applying portion 550 and a portion of the outside rotational portion 453 are inserted into the concave portion so that the rotational force applying portion 550 and the outside rotational portion 453 are stably supported So that it is possible to smoothly perform rotational motion.

A member such as a bearing may be provided between the rotation force applying unit 550 and the housing 512 and between the outer rotation unit 453 and the housing 512 so as to reduce the frictional force and smooth rotation.

In one embodiment, the outer rotation part 453 may be connected to the motor shaft 452 of the motor 450. [ The motor 450, the motor shaft 452, and the outer rotation part 453 may be provided on the procedure 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 contacts the procedure handpiece 410, 453 are positioned. 4, at least a part of the outer rotation part 453 protrudes outside the handpiece 410 and is inserted into the recess of the housing 512, so that the outer rotation part 453 and the rotation force application part 550 Can be maximized. Of course, although not shown, a method in which the surface of the housing 512, to which the rotational force applying unit 550 is contacted, protrudes in the direction of the outer rotation part 453 and the protruded part is inserted into the procedure handpiece 410 It is possible.

The converting unit is provided between the rotational force applying unit 550 and the transducer 514 and performs a function of converting the rotational motion of the rotational force applying unit 550 into linear motion and providing the rotational motion 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 rotational force applying portion 550. The other end of the cylindrical cam 541 is rotatably coupled to the housing 512. 4, a groove is provided 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 rotational force applying unit 550 receives the rotational force from the outside rotational unit 453 and performs the rotational motion, the cylindrical cam 541 can also perform rotational motion. 4 and the like illustrate a manner in which the cylindrical cam 541 and the rotational force applying unit 550 are formed as respective units and coupled to each other. However, it will be understood that the cylindrical cam 541 and the rotational force applying portion 550 may be integrally formed. However, since the rotational force applying unit 550 needs to be made of a magnetic material or magnetic material for magnetic connection with the outer rotation unit 453, it is not necessary to implement the cylindrical cam 541 with a magnetic material, It is advantageous to combine the cylindrical cam 541 and the rotational force applying part 550 with each other after implementing them with different materials. At this time, at least one locking protrusion is provided on the coupling portion between the cylindrical cam 541 and the rotational force applying portion 550 so that the rotational motion of the rotational force applying portion 550 can be transmitted to the cylindrical cam 541 effectively.

The 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 You can achieve a circle of one wheel. In this case, while the cylindrical cam 541 rotates 360 degrees, the feeding member 531 and the transducer 514 move linearly along the guide portion 533 and return to the original position, that is, perform a so-called linear reciprocating motion . At this time, the rotational speed of the cylindrical cam 541 can be adjusted in consideration of the linear reciprocating speed of the transducer 514, the rotational speed of the motor 450 can be adjusted, (Not shown) or the like between the rotating shaft 453 and the rotating shaft 453.

In another embodiment, the groove portion 541H provided on the surface of the cylindrical cam 541 may be formed to proceed only in 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. In the ultrasonic generator 20 according to the embodiment of the present invention, the rotation force application unit 550 and the outer rotation unit 453 are coupled by the magnetic force. Therefore, when the rotation direction is suddenly changed, The magnetic coupling between the outer rotating part 453 and the outer rotating part 453 can be momentarily disconnected. Therefore, the diameter and rotational speed of the cylindrical cam 541 can be determined in consideration of the linear reciprocating speed of the transducer 514 and the magnetic coupling force between the rotational force applying portion 550 and the outer rotational portion 453.

Meanwhile, the ultrasonic wave generating apparatus 20 according to an embodiment of the present invention may include position sensing means and control means. Here, the position sensing means senses the position of the ultrasonic wave generating unit, and the control means controls the ultrasonic wave generating operation using the result sensed by the position sensing means. For example, after the ultrasonic wave is generated in a state where the ultrasonic wave generator is at one position, the ultrasonic wave generator can be controlled not to generate ultrasonic waves in a state where the ultrasonic wave generator is not moved by a predetermined distance.

If the ultrasound generated by the ultrasound generating unit is HIFU, thermal lesions are formed in specific areas. If the lesions are overly continuous at the same position, there is a risk that the human tissue may be damaged. That is, if a thermal lesion is formed after a thermal lesion is formed in a specific region and the ultrasonic wave generation unit is not moved a certain distance, a certain point of the human tissue may be excessively stimulated, resulting in pain, bleeding, and injury. However, according to an embodiment of the present invention, if the ultrasonic wave generator is not moved beyond a predetermined distance immediately after the ultrasonic wave generator is generated, the ultrasonic wave generator can be operated so as not to generate ultrasonic waves. Here, the movement of the ultrasonic wave generator can be detected by the position sensing means described above. Based on the detection result, the control means controls the generation of ultrasonic waves by the ultrasonic wave generator, thereby reducing the risk that ultrasonic waves are excessively irradiated to specific positions It can be. The 'predetermined distance' may be appropriately determined according to the intensity of the ultrasonic wave generated in the ultrasonic wave generator, the size of the thermal lesion, the type of the tissue to be irradiated with the ultrasonic wave, and the like.

The ultrasonic wave generating unit includes the transducer 514 and the transferring member 531. Since the transducer 514 performs a linear motion in a state where the transducer 514 is coupled to the transferring member 531, It can perform its function by sensing the position of the transducer 514 or the transport means. Further, since the conveying unit performs linear motion in accordance with the rotation of the cylindrical cam 541, the position of the ultrasonic wave generator can be detected by sensing the degree of rotation of the cylindrical cam 541. [

In one embodiment, the position sensing means may comprise a magnet portion and a sensor, wherein the sensor may be a Hall sensor. The signal output from the sensor is changed in accordance with the positional relationship between the magnet portion and the hall sensor, and the relative positional relationship between the magnet portion and the sensor can be detected using this degree of change.

More specifically, the ultrasonic wave generating apparatus 20 according to an embodiment of the present invention may include a first magnet portion 541m provided in the cylindrical cam 541 and a first sensor S1 disposed opposite to the first magnet portion 541m. have. The first magnet portion 541m is provided at the other end of the cylindrical cam 541 so that the first sensor S1 is disposed at the first end of the cylindrical cam 541, It is desirable to be able to more accurately detect the position or movement of the magnet portion 541m. In the drawings, the first magnet portion 541m is illustrated as being provided in the cylindrical cam 541, but the first sensor may be provided in the cylindrical cam 541 as the case may be. Compared with the case where the first sensor is provided in the cylindrical cam 541 for performing rotational motion in transmitting the signal output from the first sensor to the controller 440, the housing 512 or the first frame 522 ) May be advantageous in simplifying the structure and improving the manufacturing efficiency.

Accordingly, the degree of rotation of the cylindrical cam 541 can be precisely measured, and as a result, the position of the ultrasonic wave generator can be determined.

The ultrasonic generator 20 according to another embodiment of the present invention may include a second magnet portion 531m provided in the ultrasonic wave generator and a second sensor S2 provided opposite to the second magnet portion 531m. 4 and the like illustrate the case where the second magnet portion 531m is provided in the transfer member 531. It is understood that the second magnet portion 531m may be provided in the transducer 514 There will be. Although the second magnet portion 531m is illustrated as being mounted on the transfer member 531 in the drawings, the second sensor may be provided on the transfer member 531 in some cases. Compared to the case where the first sensor is provided on the conveying member 531 for performing linear motion in transmitting the signal output from the second sensor to the controller 440, the housing 512 or the second frame 525 ) May be advantageous in simplifying the structure and improving the manufacturing efficiency.

Meanwhile, the second sensor S2 may be provided at a position opposite to the second magnet portion 531m. As described above, the transporting member 531 and the transducer 514 perform a linear reciprocating motion within the first cartridge 510, so that the movement range is limited. That is, only in a region between the position at which the transfer member 531 is farthest from the rotational force applying unit 550 and the position at which the transfer member 531 is closest to the rotational force applying unit 550, the transfer member 531 performs a linear reciprocating motion As a result of this. Here, the position at which the conveying member 531 is farthest away from the rotational force applying unit 550 is referred to as a first reference point, and the position of the conveying member 531 closest to the rotational force applying unit 550 may be regarded as a second reference point . In this case, the second sensor S2 may be provided at a position closest to the second magnet portion 531m when the transfer member 531 is located at the first reference point. In addition, the second sensor S2 may be provided at a position closest to the second magnet portion 531m when the transfer member 531 is located at the second reference point. Accordingly, the position sensing unit can accurately detect the position of the ultrasonic wave generator even at the turning point where the motion direction of the ultrasonic wave generator is switched. In addition, the instant when the linear motion of the ultrasonic wave generator starts and ends at one cycle can be precisely detected. That is, the initial position of the ultrasonic wave generator and the movement end position of the ultrasonic wave generator can be precisely detected.

In the system in which the rotational force is transmitted in a state where the rotational force applying unit 550 and the outside rotational unit 453 are not coupled due to direct contact but are connected by the magnetic force, the rotational motion of the outer rotational unit 453, The motion may not completely match. As a result, it may not be possible to precisely measure the position of the ultrasonic wave generator or to control the degree of movement of the ultrasonic wave generator simply by controlling or measuring the degree of rotation of the outer side rotary part 453. Therefore, unless there is a separate means for precisely grasping the position of the ultrasonic wave generator, there is a risk that the ultrasonic waves are excessively irradiated to a specific position as described above, causing various problems.

However, since the ultrasonic generator 20 according to an embodiment of the present invention includes the position sensing unit and the control unit described above, the position of the ultrasonic generator can be accurately grasped and reflected in the ultrasonic wave generation operation control. It becomes possible to remarkably reduce it.

Meanwhile, a separate frame or the like may be provided inside the housing 512 so that the first sensor S1, the second sensor S2, etc. may be fixed at appropriate positions. The first sensor S1 can be fixed to the first frame 522 provided in front of the cylindrical cam 541 and the second sensor 521 can be fixed to the second frame 525 provided on the side of the cylindrical cam 541 S2 can be fixed. Here, the axial projection 542 of the cylindrical cam 541 can also be inserted into the first frame 522 and fixed rotatably. In addition, a plurality of the first sensor S1 and the first magnet portion 541m may be provided so as to detect the rotation of the cylindrical cam 541 more accurately. The first terminal 512T1 connected to the first sensor S1 and the second terminal 512T2 connected to the second sensor S2 are exposed to the outside of the housing 512, The signals output from the first sensor S1 and the second sensor S2 may be transmitted to the controller 440 by contacting the first contact 410T1 and the second contact 410T2. The control unit 440 may be connected to the motor 450 to control the rotation of the motor 450 and the motor 450 may be fixed within the handpiece 410 through the third frame 415. [ have.

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 lesion is generated can approach the surface of the skin.

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. This fluid may also serve to cool 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 ultrasonic generator 20 according to the embodiment of the present invention, the rotational force applying unit 550 provided inside the cartridge is supplied with rotational force from the outside rotational unit 453 provided outside the cartridge, The transducer 514 can be linearly or linearly reciprocated. In addition, since the rotational force applying unit 550 and the outer rotation unit 453 can be connected by the magnetic force, the degree of sealing of the first cartridge 510 can be improved. That is, the ultrasonic wave generating apparatus 20 according to an embodiment of the present invention may be configured to transmit ultrasonic waves to the transducer 50 using the driving force externally of the first cartridge 510 without the components penetrating the outer wall of the first cartridge 510 or the housing 512, The ducer 514 can be moved linearly or linearly.

Therefore, the ultrasonic wave generating apparatus 20 according to the embodiment of the present invention is improved in the degree of sealing of the cartridge as compared with the case where a component for moving the transducer 514 through the outer wall of the cartridge or the housing 512 is required The replacement cycle of the cartridge can be prolonged and convenience in use and maintenance of the ultrasonic generator 20 can be improved. In addition, the ultrasonic generator 20 according to the embodiment of the present invention does not need to have any additional means for improving the degree of airtightness of the cartridge, and it is also possible to use the rotation force applying unit 550 and the converting unit Since the transducer 514 can be linearly or linearly reciprocated by a simplified structure, it is advantageous in downsizing the cartridge or the handpiece 410 and reducing the manufacturing cost.

The second cartridge 510-1 and the third cartridge 510-2 can also be implemented in a manner similar to that of the first cartridge 510. Therefore, It is omitted.
