6 to 10 are views for explaining an ultrasonic wave operation apparatus 2000 according to another embodiment of the present invention.

Referring to FIGS. 1 to 10, the ultrasonic treatment apparatus according to an embodiment of the present invention can spirally move the ultrasonic treatment unit on the driving planes PL. Accordingly, in the above-described embodiment, the procedure for the wider area can be performed more simply and quickly than in the case where the ultrasonic treatment unit performs the forward or backward movement.

Further, in the present embodiment, the helical movement of the ultrasonic treatment section can be realized on a plurality of drive planes. This makes it possible to effectively remove sweat glands located irregularly in distribution, depth and size from the skin surface.

In one embodiment, the first drive portion may include at least one of a first bevel gear 161, a second bevel gear 162, a drive pin 163, a drive pin guide 164, and a rotation guide 165 have.

The first bevel gear 161 may be rotated inside the cartridge housing 110 by receiving a rotational force from the outside of the cartridge housing 110. In this embodiment, For example, the rotational force of the second motor 135 mounted on the handpiece 200 may be transmitted to the first bevel gear 161 through the driving shaft 136 as illustrated in FIG. The second bevel gear 162 may be engaged with the first bevel gear 161 and rotated in accordance with the rotational movement of the first bevel gear 161. [ The rotation axis of the first bevel gear 161 may be referred to as a first rotation axis X1 and the rotation axis of the second bevel gear 162 may be referred to as a second rotation axis X2. The first rotation axis X1 may be perpendicular to the drive plane PL in which the ultrasonic treatment unit is helically moved. That is, the first rotation axis may be parallel to the normal line of the drive plane PL. The second rotation axis X2 may be parallel to the drive plane PL and the drive pin 163 may also be rotated about the second rotation axis X2. The relationship between the first rotation axis X1, the second rotation axis X2 and the drive plane PL is illustrated in Fig. 8, and the trajectory TRAJ of the ultrasonic wave therapy unit which is spirally formed on the drive plane PL can be understood .

In one embodiment, the driving pin guide 164 is an element in which the driving pin 163 is rotatably fixed, and is rotatable about the first rotation axis X1. A rotary guide 165 that rotates about the rotation axis of the first bevel gear 161 is provided and one side of the drive pin guide 164 is coupled to the rotation guide 165 to rotate the rotary guide 165 The driving pin guide 164 can be rotated around the first rotation axis X1. At this time, the driving pin 163 can be rotated about the second rotation axis X2 by the rotational force of the second bevel gear 162, and as a result, the transducer 151 moves in a direction away from the first rotation axis X1 Can be moved. At this time, when the rotation direction is changed, the transducer 151 may be moved in a direction to approach the first rotation axis X1. This operating principle can be easily understood from FIG. However, in FIG. 9, the linear movement distance of the transducer 151 relative to the rotation amount of the rotation about the first rotation axis X1 can be appropriately adjusted as necessary.

The rotation of the first bevel gear 161 is transmitted to the second bevel gear 162 so that the second bevel gear 162 is rotated and the drive pin guide 164 is rotated along the first rotation axis X1, As shown in Fig.

In one embodiment, the drive pin 163 may be provided with a second guide 172 and the second guide 172 may be coupled to an ultrasound therapy unit. Here, similarly to the above-described embodiment, the ultrasonic wave treatment unit may also include the first guide 152 and the transducer 151 in this embodiment.

In one embodiment, although not shown, the distance between the transducer 151 and the second guide 172 can be increased or decreased. Although not shown, the rotation guide 165 may be moved up or down along the first rotation axis. In this case, the depth of the thermal focus 10 can be adjusted even if the distance between the transducer 151 and the second guide 172 is not increased or decreased. Here, the rotation guide 165 itself may be moved up or down along the first rotation axis XL1, and the entire third guide part (180 of FIG. 6) for fixing the rotation guide 165 may be moved along the first rotation axis XL1, Or may be lowered in a direction parallel to the direction of the arrow.

In one embodiment, the rotational speed of the rotation guide 165 may be different from the rotational speed of the first bevel gear 161. The drive shaft 136 is inserted into the rotation guide 165 and coupled to the first bevel gear 161 so as to indirectly connect the drive shaft 136 and the rotation guide 165, To the rotation guide 165, as shown in FIG.

The ultrasonic wave operation apparatus 2000 according to an embodiment of the present invention may further include a second sensor unit 190. The second sensor unit 190 may sense the position and / or degree of rotation of the transducer 151. In one embodiment, the degree of rotation about the first rotation axis X1 through the second sensor unit 190 can be sensed. For example, the through hole 137 is provided in the drive shaft 136 for transmitting the rotational force of the second motor 135, and the light emitting portion 191 and the light receiving portion 192 are disposed on both sides of the drive shaft 136 Thereby sensing the rotation of the drive shaft 136. [0064]

In one embodiment, the position of the transducer 151 can be sensed through the second sensor portion 190. For example, at least one of the components (the first guide 152 and the second guide 172) moved with the transducer 151 is provided with a magnetic portion 196, and the handpiece 200 is provided with a hole A sensor 195 may be provided. Accordingly, the position of the transducer 151 can be more accurately detected and utilized for control.

The light emitting unit 191, the light receiving unit 192, the hall sensor 195 and the like may be provided in the handpiece and the magnetic force unit 196 may be provided inside the cartridge housing 110. The inside of the cartridge housing 110 must be filled with liquid for ultrasonic wave transmission and cooling of the transducer. The magnetic portion 196 can be realized by a normal magnet so that it can be in contact with the liquid, while the light emitting portion 191 ), The light-receiving unit 192 and the hall sensor 195 must be equipped with elements for power and signal transmission, so that separate waterproof measures are required if they are to be in contact with liquid. However, according to the embodiment of the present invention, since the light emitting unit 191, the light receiving unit 192, the hall sensor 195 and the like are provided in the handpiece 200, they are isolated from the liquid, . In one embodiment, the circuit board CB is provided inside the handpiece 200, and the light emitting portion 191, the light receiving portion 192, the hall sensor 195, and the like are disposed on the circuit board CB Manufacturing efficiency and space usability can be improved.

Referring to FIG. 10 and the like, the first guide 152-1 may be bent so that the distance between the transducer 151 and the first rotation axis X1 may be minimized. 9, the transducer 151 can be positioned between the second guide 172 and the first rotation axis X1, and the transducer 151 can be positioned between the second guide 172 and the first rotation axis X1, It is. Accordingly, the efficiency of the procedure can be improved since the transducer 151 can reach the vicinity of the center of the helical rotation in spite of the coupling relationship of the first and second bevel gears.

In general, if the distance between successive thermal focal points is excessively close, the risk of damaging the skin tissue is high, thereby forming thermal foci while maintaining a predetermined safety distance. That is, when the second shot is performed immediately after the first shot, there is a limit in reducing the distance between the thermal focus by the first shot and the thermal focus by the second shot. However, according to the present embodiment, since a predetermined time is required for the ultrasonic treatment unit to rotate 360 degrees, the interval between the spirals can be narrowed. As a result, the risk of damaging the skin tissue is reduced, The therapeutic efficacy can be improved.
