Abstract
Description
Technical Field
[0001] The present invention relates to a light irradiation device and a irradiation method for forming small holes in the skin by using light such as laser. Background Art
[0002] In order for drugs for skin disease treatment or skin beauty to be effectively absorbed into the skin, it is necessary to form small pores in the skin.
[0003] To create small holes in the skin, needles and lasers can be used.
[0004] Skin puncture with a needle requires a high level of proficiency on the part of the operator and may also induce severe pain.
[0005] Compared with general light, laser has the characteristics of linear transmission without dispersion and can achieve strong output in a short time with a single wave field. As mentioned above, laser is a non-ionized light that can achieve high output, has excellent monochromaticity and does not disperse. Therefore, when laser light is absorbed by skin tissue, it will cause deformation in the corresponding skin due to heating and photochemical changes. Summary of the invention
[0006] Technical issues to be solved
[0007] An object of the present invention is to provide a light irradiation device and a light irradiation method that target the upper dermis layer up to a depth of about 300 μm from the skin surface.
[0008] Means used to solve problems
[0009] The irradiation device of the present invention may include: a generating unit for generating a perforating light for forming a small hole in the skin; and an irradiating unit for irradiating the perforating light onto the skin; the irradiating unit may irradiate the perforating light multiple times with a target point set on the skin as the object.
[0010] The irradiation method of the present invention may include: a aiming step of aiming the irradiation light at the skin; a first irradiation step of irradiating a first target point among a plurality of target points existing in a set area formed based on the irradiation light with a perforating light for forming a small hole in the skin; and a second irradiation step of irradiating the perforating light to a second target point existing in the set area after completing the irradiation of the perforating light to the first target point.
[0011] The second irradiation step may be performed after all the first irradiation steps are completed.
[0012] In the first irradiation step, the first target point may be intermittently irradiated with the perforating light within a first set time.
[0013] In the irradiation method of the present invention, when irradiating perforating light to multiple target points existing in a set area formed based on the irradiation light irradiated to the skin, a first cycle action of irradiating the perforating light within a first time and then stopping irradiating the perforating light within a second time can be repeatedly performed a set number of times on the specific target points on the skin.
[0014] In the irradiation method of the present invention, after the first cycle operation is repeatedly executed the set number of times with the specific target point as the object, other target points existing in the set area may be automatically selected.
[0015] In the irradiation method of the present invention, the first cycle operation may be repeatedly performed a set number of times with respect to the selected other target points.
[0016] In the irradiation method of the present invention, the set area may be fixed until the first cycle operation is performed once or more for all of the plurality of target points existing in the set area.
[0017] The irradiation method of the present invention may include: a step of determining the period and energy of a first laser having a shorter period and stronger energy than a second laser targeting the lower dermis layer; and a step of irradiating the upper dermis layer with the first laser multiple times.
[0018] Effects of the Invention
[0019] By using the irradiation method and irradiation device of the present invention, the upper dermis layer which is difficult to achieve using conventional laser technology can be targeted.
[0020] The present invention can particularly utilize CO2 laser to induce heating and photochemical changes in the upper dermis layer formed at a depth of about 300 μm from the skin surface. Through the changes, small holes extending from the skin to the interior of the upper dermis layer can be formed. Through the holes, medical drugs or cosmetic drugs can penetrate into the interior of the upper dermis layer and be directly absorbed by the upper dermis layer or induce various effects.
[0021] In addition, through the irradiation device and irradiation method of the present invention, laser light with energy that may cause skin damage can be cut into multiple shorter segments and irradiated onto the skin, thereby alleviating various side effects.
[0022] The present invention can minimize thermal damage to surrounding tissues and cause deformation of the upper dermis or formation of small holes in the upper dermis by concentrating the energy transmitted to the target tissue, thereby causing almost no side effects such as burns and pain. In addition, compared with the conventional method of targeting the lower dermis, unnecessary skin irritation can be minimized, thereby significantly shortening the recovery period.

[0042] Furthermore, in this specification, detailed descriptions of well-known functions and configurations that may obscure the gist of the present invention will be omitted.
[0043] Figure 1 This is a perspective view illustrating the irradiation device of the present invention. Figure 2 This is a block diagram illustrating the irradiation device of the present invention.
[0044] The irradiation device of the present invention may include a cylindrical body 101, a generating unit 130 mounted on the body 101, an interface unit 109 mounted on the body 101, a trigger unit 110, an arm 103 rotatably connected to the body, and an irradiation unit 105 mounted on the end of the arm 103.
[0045] The main body 101 may be formed in various three-dimensional shapes such as a column, a box, etc., and a blank space for installing the generating unit 130 etc. may be formed inside the outer shell exposed to the outside.
[0046] The generating section 130 may generate perforating light for forming a small hole in the skin 90. As an example, the perforating light may include a carbon dioxide (CO2) laser or the like.
[0047] Carbon dioxide (CO2) laser is a typical gas laser that can oscillate in the infrared region near 9.2μm and 10.8μm by causing density inversion between the vibration energy levels of gaseous carbon dioxide. Invented in 1964 by Chandra Kuma Patel of Bell Laboratories in the United States, it has the advantage of being able to easily obtain several kW of output due to its high efficiency. Until now, CO2 lasers are still used in the industrial and medical fields as high-output lasers in the 9.4μm and 10.6μm regions.
[0048] The interface unit 109 is mounted on the main body 101 and can be exposed to the outside for naked eye observation or manual operation by the user. As an example, the interface unit 109 may include a touch screen for displaying various information and for generating various input signals by the user. As another example, the interface unit 109 may include a display screen for displaying various information and input components such as buttons for generating various input signals.
[0049] The trigger part 110 can generate a driving signal for driving the generating part 130 or the irradiating part 105 according to the operation of the user. The driving signal can control the generating part 130 or the irradiating part 105 to irradiate the perforating light to the skin. The trigger part 110 can be formed integrally with the interface part 109 or formed separately. As an example, the trigger part 110 can include a pedal operated by the user with a foot.
[0050] The arm 103 may be formed in a rod-like shape. When a plurality of arms 103 are provided, the plurality of arms 103 may be movably connected to each other via joints.
[0051] A waveguide or the like for guiding the punched light generated in the generating unit 130 to the end of the arm 103 may be formed in the arm 103 .
[0052] The irradiation unit 105 can irradiate the perforating light to the skin. The irradiation unit 105 can adjust the posture of the arm 103 so that the aiming line is directed toward the target skin.
[0053] In order to deform the skin of a specific target point portion, such as forming a small hole, by heating and photochemical changes, a comparative example of continuously irradiating perforating light for a long time can be assumed.
[0054] Conventional skin beauty or medical skin treatment targets the lower dermis of the skin. Therefore, perforation devices such as needles, injections, and lasers used to form small holes in the skin in order to guide various drugs existing outside the skin to the lower dermis mainly focus on forming small holes that penetrate into the lower dermis.
[0055] As an example, the comparative examples mentioned above target the lower dermis layer in order to cause stronger and deeper stimulation to the skin. However, it has been confirmed in recent papers and clinical trials that targeting the upper dermis layer is more effective for specific skin treatments and skin beauty.
[0056] The dermis of the skin is composed of two layers. The fibroblasts in the lower dermis (Reticular layer) produce collagen that causes scars in order to protect the skin, while the fibroblasts in the upper dermis (Papillary layer) are cells that can repair the skin without causing scars. Therefore, when the purpose of skin beauty is to target the upper dermis, it will be more effective.
[0057] However, it is still difficult to target the upper dermis by simply reducing the laser energy for continuous irradiation as described in the comparative example. This is because when the laser energy is reduced in the comparative example, it will lead to the problem that small holes cannot be formed in the skin. On the contrary, when the laser energy is increased to a level that can form small holes in the skin, it will lead to the problem that the small holes extend to the original target, that is, the lower dermis.
[0058] Therefore, a new solution is needed that can form small holes that do not invade the lower dermis but only extend to the upper dermis. For reference, the "upper dermis" described in this specification may refer to the papillary dermis, and the "lower dermis" may refer to the reticular dermis.
[0059] In order to form a small hole that does not invade the lower dermis layer but only extends to the upper dermis layer, the irradiation unit 105 of the present invention can irradiate the target point set on the skin with perforating light multiple times.
[0060] Figure 3 This is a schematic diagram illustrating a cross section of the skin.
[0061] The dermis exists below the epidermis (epidermis), and the dermis can be divided into the upper dermis (Papillary layer) located just below the epidermis and the lower dermis (Reticular layer) located just below the upper dermis.
[0062] The purpose of the irradiation device of the present invention is to form micro-pores extending from the outer side of the epidermis to a depth of less than 300 μm. Compared with the comparative embodiment, the irradiation part 105 of the present invention can form micro-pores with a depth of 300 μm by increasing the peak power and extending the pulse duration. By forming micro-pores, various drugs (effective substances) can be easily delivered to the upper dermis, and the thermal damage, side effects and pain induced in the process of forming micro-pores can be minimized.
[0063] The irradiation part 105 can form tiny holes using CO2 laser, activate fibroblasts through mechanical stimulation, thereby promoting the production of collagen and elastin, and induce skin regeneration by transferring heat energy to the skin. In addition, the 300μm deep holes formed by the irradiation part 105 can be used as a channel for transferring effective substances to fibroblasts in the upper dermis layer.
[0064] The irradiation unit 105 of the present invention may operate in a first mode of intermittently irradiating a specific target point on the skin with a perforating light.
[0065] The irradiation unit 105 may maintain the first mode without changing the specific target point until the specific target point is irradiated with the perforating light a set number of times through the first mode.
[0066] Figure 4 This is a schematic diagram illustrating the laser beam of a comparative example. Figure 5 This is a schematic diagram illustrating the perforation light beam of the present invention.
[0067] In order to form a small hole extending from the skin boundary to the lower dermis, it is assumed that the second laser 14 is continuously irradiated to a specific target point on the skin with a second amount of energy for a second set time e2. In this case, the second laser 14 can be equivalent to the comparative example.
[0068] The second laser 14 may include a CO2 laser that continuously irradiates without interruption for the second set time e2. The second laser 14 may form a small hole in the lower dermis layer extending to a depth of 1 to 2 mm.
[0069] like Figure 4 As shown in d1 in FIG. 1 , a large area of skin is damaged or burned by the second laser 14. Therefore, in the comparative embodiment, since the damaged skin area is large, there are problems such as strong pain inducing during the process of forming the small hole and a long recovery time.
[0070] The generator 130 can generate the first laser beam 104 having energy greater than or equal to the first energy within a range that medically ensures patient safety. The upper limit of the range that ensures patient safety can be defined as a limit value set medically to prevent burns.
[0071] The irradiation unit 105 may divide the first set time e1 into a plurality of first intervals f1 for irradiating the first laser 104 to a specific target point and a plurality of second intervals f2 for not irradiating any laser light, which are alternately arranged.
[0072] The irradiation unit 105 may aim at only one specific target point among the plurality of target points within the first set time e1.
[0073] The irradiation unit 105 may irradiate the specific target point with the first laser 104 in each first interval f1 of the first set time e1. At this time, the continuous duration (maintenance time) of the first laser 104 may be the same as the duration of the first interval f1. Because the second interval f2 appears immediately after the first interval f1, the continuous irradiation of the first laser 104 will be stopped, and the irradiation may be restarted in the next first interval f1.
[0074] The irradiation unit 105 may not irradiate the specific target point with the first laser beam 104 in each second interval f2 of the first set time e1. In the present invention, the process of irradiating the specific target point and not irradiating the perforating beam may be repeated a set number of times.
[0075] The first set time e1 may be 0.5 to 10 times the second set time e2.
[0076] The second interval f2 of the first set time e1 may be set to a time 5 to 15 times that of the first interval f1. In this case, the first interval f1 may be determined within a range of 15 μs or less. For example, the first interval f1 may be determined within a range of 1 ns to 15000 ns.
[0077] The first laser beam 104 irradiated from the irradiation unit 105 can form a small hole that reaches a boundary line between the lower dermis layer and the upper dermis layer.
[0078] At least one of the type of perforating light, the first set time e1, the number of times the perforating light is irradiated to the first target point within the first set time e1, the diameter of the perforating light, the energy of the perforating light, the distance between multiple target points in the set area, and the maintenance time of each perforating light irradiated to the first target point multiple times within the first set time e1 can be determined within the range before the depth of pore formation reaches the lower dermis from the skin surface.
[0079] As an example, the generating unit 130 may generate CO 2 laser light having a wavelength of 10.6 μm.
[0080] The irradiation unit 105 may irradiate the CO 2 laser in the first adjustment mode or the second adjustment mode.
[0081] Both the first adjustment mode and the second adjustment mode can be working modes in which CO2 laser is irradiated in the first interval f1 on the timeline and CO2 laser is stopped in the second interval f2. However, the first adjustment mode and the second adjustment mode may differ in the number of times the first interval f1 takes the specific target point as the object.
[0082] As an example, when defining a unit period for combining a first interval f1 and a second interval f2, different first numbers and second numbers may be set.
[0083] The first number may be the number of times the specific target point is continuously repeated as a unit cycle in the first adjustment mode. The second number may be the number of times the specific target point is continuously repeated as a unit cycle in the second adjustment mode. If other adjustment modes are further needed, a third adjustment mode with a third number different from the first number and the second number may be added.
[0084] The irradiation unit 105 may irradiate the CO 2 laser in accordance with any one of the first adjustment mode, the second adjustment mode, and the third adjustment mode. The selection of the first adjustment mode, the second adjustment mode, and the third adjustment mode may be performed through the interface unit 109 .
[0085] Through the first adjustment mode, the second adjustment mode and the third adjustment mode, the position of the end of the small hole can be adjusted within the range of the upper dermis layer. When the depth of the small hole formed by the first adjustment mode is the shallowest, the depth of the small hole formed by the third adjustment mode can be the deepest.
[0086] In the present invention, in which the first interval f1 and the second interval f2 are alternately arranged, the perforated light can be arranged as follows: Figure 5 The method shown in the figure irradiates a specific target point multiple times in a short period of time. Figure 5 As shown, the area d2 of the part damaged or burned by the perforating light can be greatly reduced.
[0087] Furthermore, from the perspective of a specific target point, the irradiation unit 105 irradiates the perforating light in the first interval f1 of the first set time e1, and does not irradiate the perforating light in the second interval f2. In other words, from the perspective of a specific target point, the second interval f2 may be equivalent to an idle interval in which the irradiation unit 105 does not operate.
[0088] In order to realize the high-speed skin treatment and the high-speed perforating light irradiation, a scheme may be provided in which the perforating light is irradiated to other target points by using the irradiation unit 105 in an idle state in the second interval f2 targeting a specific target point. In this embodiment, from the perspective of another target point, the perforating light may be irradiated in each second interval f2 of the first set time e1, and the perforating light may not be irradiated in each first interval f1.
[0089] As an example, the irradiation unit 105 may divide the first set time e1 in a manner that a plurality of first intervals f1 for irradiating the perforating light and a second interval for not irradiating the perforating light are alternately arranged. The irradiation unit 105 may irradiate the perforating light with the first target point on the skin as the object in each first interval f1 of the first set time e1. The irradiation unit 105 may irradiate the perforating light with the second target point on the skin as the object in each second interval f2 of the first set time e1 in which the perforating light is not irradiated to the first target point.
[0090] In this embodiment, the irradiation of the perforating light to at least two target points can be completed within the first set time e1.
[0091] Furthermore, in order to guide the user who uses the irradiation device to aim the irradiation part 105 at the treatment site of the skin, irradiation light may be used.
[0092] As an example, the irradiation unit 105 may irradiate irradiation light for indicating a target point to the skin. The irradiation light may be used for the purpose of visually targeting a specific position without causing irritation to the skin.
[0093] The user can use the irradiated light to intuitively confirm the current target skin area.
[0094] Based on the irradiation light, multiple target points arranged in a grid structure can be set in a set area on the skin. The multiple target points can be visually displayed on the skin by the irradiation light.
[0095] The irradiation unit 105 may operate in a first mode in which a specific target point within a set area is intermittently irradiated with a perforating light.
[0096] The irradiation unit 105 may operate in a second mode in which the aiming line of the perforating light is changed to another target point within the set area after completing the first mode for the specific target point.
[0097] After completing the second mode, the irradiation unit 105 may execute the first mode on other target points.
[0098] The setting area can be formed in the shape of a closed curve of various shapes. Figures 6 to 8 In FIG. 1 , setting areas a2 , a3 , and a4 having different shapes are illustrated.
[0099] Figure 6 This is a schematic diagram illustrating the first setting area. Figure 7 This is a schematic diagram illustrating the second setting area. Figure 8 This is a schematic diagram illustrating the third setting area.
[0100] The first setting area a2 can be Figure 6 The quadrilateral shape shown is formed.
[0101] The second setting area a3 can be Figure 7 The triangle shape shown is formed.
[0102] The third setting area a4 can be Figure 8 The circular shape shown is formed.
[0103] The area of each of the set regions a2, a3 and a4 may be several tens of times larger than the diameter of the target point a1. A plurality of target points a1 may be arranged in the set region.
[0104] The irradiation unit 105 may alternately execute the first mode and the second mode for a plurality of target points existing in a set area.
[0105] To form a small hole of a set depth, the irradiation unit 105 may perform the first mode and the second mode alternately again with multiple target points in the set area after completing the first mode for all target points in the set area.
[0106] In order to minimize skin damage, the irradiation unit 105 may alternately perform the first mode and the second mode on a plurality of target points existing in a set area.
[0107] At this time, after completing the first mode for all target points in the set area, the irradiation unit 105 may start again from the beginning with the set area as the target and alternately execute the first mode and the second mode with multiple target points as the target.
[0108] As another example, the irradiation unit 105 performs the first mode on other target points except the specific target point according to the second mode. Fig.10 As shown, the first mode can be re-executed for a specific target point at each set period T. In this embodiment, the first mode can be re-executed for a specific target point even before the first mode for all target points in the set area is completed. In the case described above, when the number of re-executions of the first mode for a specific target point meets the set value, the corresponding specific target point can be excluded from the re-execution object of the first mode.
[0109] The irradiation unit 105 may irradiate a plurality of target points formed in a set area on the skin with the perforating light.
[0110] The irradiation unit 105 may irradiate the individual target point with the perforating light for the first set time e1 and then irradiate the other target points.
[0111] When irradiating the individual target points with the first perforating beam, the irradiation unit 105 may irradiate the perforating beam intermittently.
[0112] Within the range of forming small holes in the upper dermis extending from the skin surface to a depth of 300 μm by intermittent irradiation of perforating light, at least one of the energy of the perforating light, the irradiation cycle of the perforating light, the number of irradiations of the perforating light and the first set time e1 can be determined.
[0113] The modes of irradiating the perforating light in the set area may include a first mode, a second mode, a third mode and a fourth mode.
[0114] The first mode may include irradiating from left to right and from top to bottom.
[0115] The second mode may include a manner of alternately performing a horizontal mode of irradiating row by row from left to right and a vertical mode of irradiating column by column from top to bottom.
[0116] The third mode may include a random manner of irradiating the perforating light.
[0117] The fourth mode may include a scattering method of selecting target points in a diffuse manner with the set target point as the center toward the periphery.
[0118] In addition, a method of sequentially irradiating multiple target points formed in a set area to relieve the patient's pain can be considered.
[0119] As an example, the irradiation unit 105 may set a plurality of target points within a set area on the skin.
[0120] The irradiation unit 105 may irradiate the perforation light while selecting a plurality of target points according to a first directivity. The first directivity may refer to an order of selecting the target points according to one of a first mode, a second mode, a third mode, and a fourth mode.
[0121] Fig. 9 This is a schematic diagram illustrating a plurality of target points formed in a set area.
[0122] When receiving a request to modify the first directivity through the input unit, the irradiation unit 105 may irradiate the perforating light while selecting a plurality of target points according to a second directivity having a tendency opposite to the first directivity.
[0123] The first directivity and the second directivity may have opposite tendencies to each other according to at least one of a distance difference based on the specific target point and an angle difference based on the center of the set area.
[0124] For example, in the first mode, after completing the first mode for the upper left target point, the first mode may be performed for the second target point from the leftmost side of the upper row.
[0125] When the patient expresses pain during the execution of the first mode, the user treating the patient may select a mode change menu through the interface unit 109. When the mode change menu is selected, the irradiation unit 105 may change the target point selection order to a second directivity different from the current first directivity.
[0126] The first directivity and the second directivity may have opposite tendencies in terms of distance or angle.
[0127] As an example, when the first directivity is a method of selecting target points from left to right, the second directivity can select the target point farthest from the current target point in the set area. When the second directivity of this embodiment is applied, the first mode for the target point at the lower right end can be executed after executing the first mode for the target point at the upper left end.
[0128] As an example, when the first directivity is a method of selecting target points in sequence from left to right, the second directivity may select a target point that is arranged at a point-symmetric position with respect to a target point that is shifted one grid from left to right. In this case, the reference of the point symmetry may be the center of the set area. In the case described above, when the second directivity is applied, after executing the first mode for the target point at the upper left end, the first mode for the target point that is the second left from the rightmost side in the lower row may be executed.
[0129] When receiving a request for re-modification of the first directivity through the input unit, the irradiation unit 105 may irradiate the perforating light while selecting a plurality of target points according to a third directivity corresponding to an average of the first directivity and the second directivity.
[0130] For example, when the user issues a modification request for the first directivity, due to the intervention of the second directivity, a target point that is 180 degrees rotated from the target point that should have been selected can be selected as the next execution object of the first mode based on the center of the set area. At this time, when the user issues a further modification request for the first directivity, a target point that is 90 degrees rotated from the target point that should have been selected can be selected as the next execution object of the first mode.
[0131] Fig.10 This is a schematic diagram illustrating the operation of the irradiation unit 105 .
[0132] It can be equipped with a trigger unit 110 that generates a driving signal for driving the generating unit 130 or the irradiating unit 105 according to the user's operation, and a locking unit that aims the irradiating unit 105 at a fixed position by limiting the movement of the arm 103 and the irradiating unit 105 when the trigger unit 110 is operated.
[0133] The lock portion may release the restriction on the movement of the arm 103 when the operation on the trigger portion 110 is released.
[0134] like Fig.10 As shown, the irradiation device of the present invention can execute the first mode for the target point ⑦ when the specific target point ⑦ is selected. At this time, the first mode can intermittently irradiate the perforating light, and the diameter of the corresponding perforating light can be about 0.2 mm.
[0135] In order to ensure that all of the multiple perforating lights intermittently irradiated accurately irradiate the target point ⑦, it is preferable to fix the irradiation unit 105 within the first set time e1 when the first mode is executed on the target point ⑦.
[0136] In this embodiment, when the trigger unit 110 for controlling the irradiation unit 105 to irradiate the perforating light is operated, the movement of the arm 103 can be restricted by means of the locking unit. Thus, in the present invention, since the movement of the irradiation unit 105 is restricted by the locking unit during the period when the perforating light is output from the irradiation unit 105, the target point ⑦ can be accurately aimed at by the irradiation unit 105 during the first mode period and a plurality of perforating lights can be irradiated to the target point ⑦.

[0138] Fig.11 The irradiation method shown in the figure may include an aiming step S510, a first irradiation step S520 and a second irradiation step S530.
[0139] In the aiming step S510, the irradiation light can be aimed into the skin. With the help of the action performed by the irradiation unit 105, the user can use the irradiation light to determine the skin position where the perforation light needs to be irradiated.
[0140] In the first irradiation step S520 , a perforation light for forming a small hole in the skin may be irradiated to a first target point among a plurality of target points existing in a set area formed based on the irradiation light.
[0141] In the second irradiation step S530 , after the perforation light is set for the first target point, the perforation light may be irradiated to the second target point existing in the set area, which may be performed by the irradiation unit 105 .
[0142] The second irradiation step may be performed after all of the first irradiation steps are completed.
[0143] In the first irradiation step, the perforating light may be intermittently irradiated with the first target point as an object within the first set time e1.
[0144] At least one of the type of perforating light, the first set time e1, the number of times the perforating light is irradiated to the first target point within the first set time e1, the diameter of the perforating light, the energy of the perforating light, the distance between multiple target points in the set area, and the maintenance time of each perforating light irradiated to the first target point multiple times within the first set time e1 can be determined within the range before the depth of pore formation reaches the lower dermis from the skin surface.
[0145] Through the irradiation device and irradiation method introduced in the above content, when irradiating perforating light to multiple target points within a set area formed based on the irradiation light irradiated to the skin, the irradiation unit 105 can repeatedly perform the first cycle action a set number of times with specific target points on the skin as the object.
[0146] At this time, the first cycle action can be Fig.10 The first cycle operation may be to irradiate the perforating light within a first time and then stop irradiating the perforating light within a second time. From another perspective, the first cycle operation may refer to the operation of the irradiation unit 105 within the unit cycle mentioned in the above content.
[0147] As an example, in Fig.10 The first cycle action is repeated 6 times starting from time point t1. The number of repetitions of the first cycle action is preferably 3 to 12 times.
[0148] After repeatedly executing the first cycle operation a set number of times with a specific target point as the target, the irradiation unit 105 may automatically select other target points existing in the set area.
[0149] The irradiation unit 105 may repeatedly perform the first cycle operation a set number of times on other selected target points.
[0150] The locking unit may fix the set area until the first cycle operation is performed once or more on all of the plurality of target points existing in the set area.
