Since the temperature after the ultrasonic irradiation does not drop much at the point close to the return point, the processor 122 may control the time t during which the irradiation of ultrasonic energy output to P2-2 is maintained to be faster.

In addition, when the processor 122 moves from the first point (A) to the second point (B), the ultrasonic energy output to each odd-numbered irradiation position (P1-1, P1-3, ..., P1-17) It can be controlled so that the time (t) for which the irradiation is maintained and the intensity (E) of the ultrasonic energy are the same. Thereafter, when the processor 122 moves from the second point (B) to the first point (A), the ultrasonic waves output to each even-numbered irradiation position (P2-2, P2-4, ..., P2-16) The intensity (E) of the energy may be controlled to gradually increase, and the time (t) during which the irradiation of ultrasonic energy is maintained may be controlled to be gradually delayed.

In addition, when the processor 122 moves from the first point (A) to the second point (B), the ultrasonic energy output to each odd-numbered irradiation position (P1-1, P1-3, ..., P1-17) It is possible to control the intensity (E) of the to gradually decrease, and when moving from the second point (B) to the first point (A), each even-numbered irradiation position (P2-2, P2-4, …, P2-) 16), the intensity (E) of the ultrasonic energy output is controlled to gradually increase, so that the temperature does not rise above the reference level.

In addition, the processor 122 is configured for each odd-numbered irradiation position (P1-1, P1-3, ..., P1-17), and each even-numbered irradiation position (P2-2, P2-4, ..., P2-16). By controlling the time (t) for which the irradiation of the ultrasonic energy output to the ultrasonic energy is maintained at a fast interval, before the temperature is lowered, the temperature is raised again, thereby increasing the skin treatment effect.

When the second irradiation mode is activated, the apparatus 100 for controlling the movement of the ultrasonic generator can maximize the treatment effect while shortening the treatment time, and can prevent the risk of burns in advance.

FIG. 7 is a diagram illustrating an example of a movement process of an ultrasonic wave generator when a third irradiation mode among irradiation modes of the processor of FIG. 1 is activated.

Referring to FIG. 7 , in the specific irradiation mode determination step, it may be determined whether the third irradiation mode among the irradiation modes of the ultrasound generator 10 is selected and activated through the processor 122 ( S410 ).

In the ultrasonic irradiation position information output step, when the third irradiation mode of the ultrasonic generator 10 is activated through the processor 122, third ultrasonic irradiation position information corresponding to the third irradiation mode may be checked and output ( S420). The third ultrasound irradiation position information may be each position information for focusing the ultrasound of the ultrasound generator 10 .

The third ultrasonic irradiation position information may be information for outputting ultrasonic waves under the same conditions to the same irradiation position when the ultrasonic generator 10 reciprocates. Here, the condition may include at least one of a time period for which the irradiation of ultrasonic energy is maintained and an intensity of ultrasonic energy.

The third ultrasonic irradiation position information is to output ultrasonic waves to the respective irradiation positions (P1-1 to P1-17) when the ultrasonic generator 10 moves from the first point (A) to the second point (B) It may be information for Here, in step (a), a normal treatment may be performed with a treatment distance of d. For example, the normal operation distance d may be 25 mm.

In addition, the third ultrasonic irradiation position information is generated when the ultrasonic generator 10 moves from the second point (B) to the first point (A) or when moving from the first point (A) to the second point (B). , may be information for outputting ultrasound to each of the irradiation positions (P2-2 to P2-17) (P1-2 to P1-17). Here, steps (b) and (c) may not output ultrasonic waves to the irradiation positions P2-1 and P1-1 in order to prevent in-situ ultrasonic irradiation. In steps (b) and (c), a partial treatment may be performed with the treatment distance of d2, except for the treatment distance of d1. For example, the excluded treatment distance d1 is 1 mm to 2.5 mm, and the partial treatment distance d2 is d-d1, and may be 22.5 mm to 24 mm.

Here, the irradiation position of P2-2 is the same as the irradiation position of P1-16, and the irradiation position in the P2-2 -> P2-17 direction is the irradiation position in the P1-16 -> P1-1 direction, respectively. It may be in the same location.

In addition, the intensity (E) of the ultrasonic energy output to P1-1 to P1-17 and the intensity (E) of the ultrasonic energy output to P2-2 to P2-17 may be the same or different from each other.

In addition, the time (t) for which the irradiation of ultrasonic energy output to P1-1 to P1-17 is maintained and the time (t) for which the irradiation of ultrasonic energy output to P2-2 to P2-17 is maintained is equal to or , may be different from each other. For example, the time (t) during which the irradiation of ultrasonic energy output to P1-1 to P1-17 is maintained is faster than the time (t) during which the irradiation of ultrasonic energy output to P2-2 to P2-17 is maintained. or it may be late.

In the step of moving the ultrasonic generator, the ultrasonic generator 10 through the transfer unit 110 on the basis of the third ultrasonic irradiation position information output through the processor 122, each irradiation corresponding to the third ultrasonic irradiation position information. It can be moved to the positions (P1-1 to P1-17) (P2-2 to P2-17) (S430).

In the ultrasonic irradiation step, when moved to each irradiation position (P1-1 to P1-17) (P2-2 to P2-17) through the transfer unit 110, the skin ( The ultrasonic wave generator 10 may be controlled through the processor 122 to irradiate ultrasonic waves at intervals S) (S440).

Here, the ultrasonic focusing depth when the ultrasonic generator 10 moves from the first point (A) to the second point (B), and when moving from the second point (B) to the first point (A) may be different from each other. For example, the ultrasonic focus depth when the ultrasonic generator 10 moves from the first point (A) to the second point (B) is determined when the ultrasonic wave generator moves from the second point (B) to the first point (A). It can be deeper or shallower than the ultrasonic focus depth of

In addition, the processor 122 controls the intensity (E) of the ultrasonic energy output to P1-1 to P1-17 and the intensity (E) of the ultrasonic energy output to P2-2 to P2-17 to be the same or different from each other. can do.

In addition, the processor 122 is output to at least one of P2-1 and P2-2 in order not to generate an image at a point close to the return point when moving from the second point (B) to the first point (A). It is possible to control the intensity (E) of the ultrasonic energy to be weakened. Since the temperature after ultrasonic irradiation is not much lower at a point close to the return point, the processor 122 may control the intensity E of ultrasonic energy output to at least one of P2-1 and P2-2 to be weakened.

In addition, the processor 122 determines a time (t) for which the irradiation of ultrasonic energy output to P1-1 to P1-17 is maintained, and a time (t) for which the irradiation of ultrasonic energy output to P2-2 to P2-17 is maintained. ) can be controlled to be the same or different from each other. For example, the processor 122 determines a time (t) during which the irradiation of ultrasonic energy output to P1-1 to P1-17 is maintained, and a time during which irradiation of ultrasonic energy output to P2-2 to P2-17 is maintained. It can be controlled to be faster or slower than (t).

In addition, the processor 122 is output to at least one of P2-1 and P2-2 in order not to generate an image at a point close to the return point when moving from the second point (B) to the first point (A). It is possible to control so that the time (t) during which the irradiation of ultrasonic energy is maintained becomes faster. Since the temperature after the ultrasonic irradiation is not much lower at a point close to the return point, the processor 122 controls the time (t) during which the irradiation of ultrasonic energy output to at least one of P2-1 and P2-2 is maintained to be faster. can

In addition, when the processor 122 moves from the first point (A) to the second point (B), the time (t) and the intensity of the ultrasonic energy during which the irradiation of ultrasonic energy output to P1-1 to P1-17 is maintained (E) can be controlled to be the same. Thereafter, when the processor 122 moves from the second point (B) to the first point (A), the intensity (E) of the ultrasonic energy output to P2-1 to P2-17 may be controlled to gradually increase, and The time (t) during which the irradiation of ultrasonic energy is maintained may be controlled so that it becomes gradually delayed.

In addition, when the processor 122 moves from the first point (A) to the second point (B), the intensity (E) of the ultrasonic energy output to P1-1 to P1-17 may be controlled to gradually decrease, When moving from the second point (B) to the first point (A), the intensity (E) of the ultrasonic energy output to P2-2 to P2-17 is controlled to gradually increase, so that the temperature does not rise above the standard. have.

In addition, the processor 122 controls the time (t) during which the irradiation of ultrasonic energy output to P1-1 to P1-17, P2-2 to P2-17 is maintained at a quick interval, before the temperature is lowered, the temperature again By increasing the, it is possible to increase the skin treatment effect.

When the third irradiation mode is activated, the device 100 for controlling the movement of the ultrasonic generator can prevent the cartridge output from being concentrated at the starting point and the ending point during the reciprocating treatment, so that the treatment effect can be reduced while reducing the treatment time. It can be maximized, and the risk of burns can be prevented in advance.

Meanwhile, the irradiation mode of the processor 122 may be set to various other irradiation methods other than the above-described irradiation method.
