Description
Description LASER HAND PIECE
Technical Field
[I] The present invention relates to a laser hand piece, and in particular, to a laser hand piece, which makes a laser distributed and converted into a plurality of irradiation beams and irradiates them on a certain area so that an operation time can be reduced and a curative effect can be maximized.
Background Art [2] In general, a method employed for curing skin disorders includes an optical curing method using lasers, ultraviolet rays, intense pulsed lights (IPL), or the like. [3] Referring to the optical curing method using the laser, the laser (Light amplification by stimulated emission of radiation) is characterized in that it is a monochromatic and parallel light other than a usual solar light and has the same phase of wave. [4] That is, it has only one wavelength, which is different from the sun light, so that it is seen as one color such as a red or yellow color in accordance with its wavelength. [5] As such, the fact that the laser has only one wavelength is a very important variable for curing disorders. [6] That is, it becomes a basis for selectively destroying a target of interest (e.g., an abnormal blood vessel or pigment) without damaging other nomral skin tissues. [7] Referring to an interaction occurring when the laser is irradiated on the skin, the ray of the laser is absorbed into a specific maerial of the skin in accordance with the wavelength of the ray when the ray of the laser is irradiated on the skin. [8] Materials constituting the skin have respective properties of easily absorbing lights of specific wavelength, which are so called a chromophore. [9] For example, an ultrared light energy emitted from a carbonic acid gas laser is usually absorbed in water. [10] However, 70% of a human body is composed of water so that the irradiated laser energies are absorbed into any areas of the human body to generate a heat, which thus causes the tissue to be damaged.
[I I] Accordingly, the CO laser is used when the tissue needs to be nonspecifically destroyed.
[12] Lights having a wavelength of 532nm, 577nm, or 585nm are easily absorbed into red blood cells within a blood vessel. [13] A melanic pigment which is a cause of a fleckle or fleck is easily absorbed into lights having wavelengths of 532nm, 755nm, and 1064nm. [14] Accordingly, when such an interaction between the laser rays and the skin tissue is
utilized, it is possible to implement a selective photothermolysis cure which only destroys the target to be cured and hardly damages other tissues.
[15] Recently, treatment apparatuses using a laser are put into a market and are employed, which inlcude:
[16] a panel manipulation unit 100 having a key input portion for setting or selecting parameter values including a scan interval, and an oscillation switch for carrying out swtiching for outputting a laser beam;
[17] a laser generation unit 200 having a high voltage generation portion for generating a high voltage according to the switching of the oscillation switch, a laser oscillation portion for receiving the high voltage to oscillate the laser beam, a cooling portion for using a distilled water as a coolant for removing causes of output change in laser beam according to a change in temperature and breakage of a plasma tube due to an overheat of the laser oscillation portion, a collimation beam emitting portion for emitting a collimation beam for taking the collimation point of emitting the laser beam, and a beam separating portion for reflecting the collimation beam and transmitting the laser beam to propagate through the same path, and a portion of reflecting or refracting the transmitted laser beam;
[18] a central control unit 300 for processing input signals of the panel manipulation unit and outputting a super pulse scanning signal and a laser oscillation control signal of the laser by means of the signal processing; and
[19] a super pulse scan unit 400 having a scanner drive portion for outputting a drive signal by means of the super pulse scanning control signal, a step motor for generating a rotative force for adjusting a direction or an angle by means of the drive signal, and a mirror for reflecting the laser output from the refracting portion of which a direction or an angle can be adjusted for allowing the reflected laser to scan an operation area of interest by means of the super pulse.
[20] In this case, a hand piece which can be freely manipulated is mounted on a leading end of the refracting portion for finally emitting the laser beam.
[21] The hand piece is a terminal for selectively adjusting and outputting a width, an interval, and a wavelength of the laser pulse for curing disorders.
[22] The conventional hand piece is composed of a flash lamp 102 for allowing the laser to be output when a power is input and a reflecting mirror 101, so that a single laser beam 90 can be irradiated as shown in FIG. 2.
[23] Accordingly, in order to irradiate the laser beam over a large area of operation, an irradiation angle must be frequently changed by controlling the step motor and the mirror by means of the control unit, which caused the operation time to be lengthened.
[24] In addition, according to the conventional hand piece, the laser beam is output onto a single point only, which limits find adjustment of the focus diameter, so that a fine ir-
radiation point (i.e., dot) can not be easily formed, a long operation time is required for a large area of operation to be cured, and a scar remains. Disclosure of Invention
Technical Problem
[25] In order to solve the problems, it is an objective of the present invention to provide a laser hand piece, which distributes a single laser beam to form an irradiation portion composed of a plurality of fine irradiation points so that a minimum number of operations can be taken for a large area of oepration to be cured and an aftereffect such as a scar does not occur by means of the fine irradation points. Technical Solution
[26] One aspect of the present invention is to provide a laser hand piece which distributes a laser beam generated from a laser generation unit by a distribution apparatus to form an irradiation portion having a predetermined area.
[27] In addition, according to the present invention, the distribution apparatus includes: a main body having a lens receiving part within the main body, a support disposed at its lower portion, and connected to the laser generation unit; a primary lens disposed in the lens receiving part and diffusing the laser beams; a secondary lens diffracting and refracting the laser beam diffused by the primary lens to form a plurality of irradiation beams; and a tertiary lens aligned for irradiating the irradiation beam passed through the secondary lens to be irradiated onto an X-Y intersection to form a laser beam irradiation portion.
[28] In addition, according to the present invention, an air spraying portion capable of spraying an air is diposed on one side of the distribution apparatus.
Advantageous Effects
[29] According to the present invention as described above, unlike a single laser beam according to the prior art, the laser beam is distributed to form a plurality of fine irrdaition points having rectangle shapes, so that a minimum number of operations can be taken for a large area of oepration to be cured and an aftereffect such as a scar does not occur by means of the fine irradation points. Brief Description of the Drawings
[30] FIGS. 1 and 2 are diagrams according to the prior art wherein FIG. 1 is a diagram illustrating a configuration of a treatment apparatau using a laser and FIG. 2 is a diagram illustrating a conventional laser hand piece.
[31] FIG. 3 is a cross-sectional view of a laser hand piece in accordance with to the present invention.
[32] FIG. 4 is a diagram illustrating a laser beam portion formed by a laser hand piece in accordance with to the present invention.
Best Mode for Carrying Out the Invention
[33] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to accompanying drawings.
[34] The same constitutional elements will be given the same reference numerals in the description of the present invention, and the overlapping descirption will be omitted.
[35] FIG. 3 is a cross-sectional view of a laser hand piece in accordance with to the present invention, and FIG. 4 is a diagram illustrating a laser beam portion formed by a laser hand piece in accordance with to the present invention.
[36] As shown in FIG. 3, the laser hand piece A according to the present invention includes: a main body 2 having a lens receiving part 20 within the main body, a support 22 disposed at its lower portion, and connected to the laser generation unit 200; a primary lens 31 for diffusing the laser beams bl; a secondary lens 32 for diffracting and refracting the laser beam bl diffused by the primary lens 31 to form a plurality of irradiation beams b2; and a tertiary lens 33 aligned for irradiating the irradiation beam b2 passed through the secondary lens 32 to be irradiated onto an X-Y intersection to form a laser beam irradiation portion having a predetermined area b3.
[37] The main body 2 is a cylindrical body receiving the primary, secondary, tertiay lenses 31, 32, 33 and has an air hole 220 at the support.
[38] The primary lens 31 is a convex lens for diffusing the laser beam bl.
[39] The secondary lens 32 is composed of a plurality of convex pixel lenses, and diffracts and refracts the single laser beam bl which has passed through the primary lens 31 through the pixel lenses to form a plurality of irradiation beams b2.
[40] In addition, degrees of diffraction and refraction can be adjusted in accordance with a thickness of surface coating of the secondary lens 32.
[41] The number of the irradiation beams b2 may be determined while they pass through the secondary lens 32 if necessary, and the laser beam irradiation portion b3 must have a square shape so that the number of the irradiation beams is preferably set to 7 x 7 or 9 x 9.
[42] The tertiary lens 33 is typically a concave lens, which prevents the irradiation beams b2 passed through the secondary lens 32 from being deviated outside and makes the irradiation beams focused within the laser beam irradiation portion b3.
[43] That is, the laser beam irradiation portion b3 is most preferably square, and is configured to allow the irradiation beam b2 to be focused and irradiated toward the inside only, and is in particular configured to allow the irradiation beam b2 to be irradiated onto an X-Y intersection after the laser irradiation portion b3 is set for X-Y coordinate values.
[44] Operations of the hand piece configured as mentioned above will be described as
follows.
[45] Examples of the laser employed for the present inveniton include a CO laser having a wavelength of 10.6nm, a Nd YAG laser having a wavelength of 1320nm, a Nd YAG laser having a wavelength of 1064nm, and an Er YAG laser having a wavelength of 2940nm.
[46] In addition, irradation of the laser is selectively determined in consideration of a degree of laser penetration, an area, and a thermal damage in accordance with a doctor's prescription.
[47] The magnitude of the laser penetration depth mentioned above is as follows: Er
YaG laser (1064nm) > Nd YAG laser (1320nm) > CO laser (10.6nm).
[48] The laser beam bl generated from the laser generation unit is diffused to have a relatively large diameter while passing through the primary lens 31.
[49] The laser beam is then divided into a plurality of irradiation beams b2 through the pixel lens while passing through the secondary lens 32.
[50] The divided irradiation beams b2 have a laser irradiation portion b3 of a substantially square shape while passing through the tertiary lens 33.
[51] Accordingly, an operation can be taken on a relatively large area to be cured to shorten an operation time, and the laser can be output as divided irradiation beams so that a damage on an affected part can be reduced.
[52] In addition, an air spraying portion (not shown) for spraying an air is further disposed on one side of the main body 2 of the hand piece. That is, the air is sprayed at a proper pressture by the air spraying portion so that a smoke generated at the time of carrying out a laser operation can be removed to implement a more comfortable and accurate operation.
[53] The air spraying portion is composed of an air compressor and a nozzle coupled to the air compressor, which is well known in the art so that a description thereof will be omitted.
[54] While the invention has been described with reference to preferred embodiments as mentioned above, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by thef olio wing claims. Industrial Applicability
[55] According to the present invention as described above, unlike a single laser beam according to the prior art, the laser beam is distributed to form a plurality of fine irrdaition points having square shapes, so that a minimum number of operations can be taken for a large area of operation to be cured and an aftereffect such as a scar does not occur by means of the fine irradation points.
